THE U.S.–CANADA TRADE WAR AT A STRATEGIC CROSSROADS


A Bayesian Game-Theoretic Assessment of Economic Coercion, Provincial and Federal Strategy, and the Future of the North American Order 


Prepared for the Council of the Federation


Farid Novin












First Draft — Situation Report — August 29, 2026



Executive Assessment

The Canada–United States trade conflict has moved into a qualitatively different phase. What began in early 2025 as a dispute over emergency-powers tariffs has become, by the fall of 2026, a structural bargaining contest over sovereignty, economic dependence, industrial geography, and the future institutional architecture of North American integration. For the premiers and territorial leaders who make up the Council of the Federation, the conflict is no longer a federal file to be monitored from a distance. It now touches provincial procurement, interprovincial trade barriers, energy corridors, automotive employment, and the fiscal room available to every jurisdiction represented at this table.

The immediate economic shock should not be exaggerated. The tariffs now in force touch a meaningful but bounded share of Canadian exports rather than the whole of the Canadian economy: independent bank estimates place the directly affected trade at roughly five percent of Canadian exports to the United States, on the order of four-tenths of one percent of Canadian GDP. But the strategic risk is considerably larger than this first-round figure suggests, because the conflict is no longer a single tariff dispute. It is a repeated, multi-front game being fought simultaneously through litigation, retaliation, provincial procurement policy, energy strategy, and public sentiment on both sides of the border.

The central Bayesian conclusion of this assessment is unchanged from earlier drafts, but it now rests on firmer legal and political ground: the probability that the current tariff confrontation is eventually negotiated down remains substantial, while the probability that it permanently changes Canada's strategic posture toward the United States is considerably higher. Ottawa and the provinces are no longer simply negotiating tariff schedules. Canada, as a federation, is beginning to operate from a revised prior in which the United States can no longer be treated as an automatically predictable economic partner. That is the meaning behind Prime Minister Carney's description of this moment as a "rupture."

I. Chronology: How the Conflict Reached This Point

A precise chronology matters for this Council because the legal basis of the tariffs now in force is materially different from the tariffs Canada faced through most of 2025, a distinction with direct consequences for how durable, and how challengeable, the current measures are.

Beginning February 1, 2025, the first Trump administration tariff wave against Canada was imposed under the International Emergency Economic Powers Act, citing fentanyl trafficking and border security as the triggering emergencies. Canada retaliated in kind through 2025, while roughly 85 percent of Canada–U.S. trade continued to move tariff-free under CUSMA exemptions. That entire legal edifice was then struck down. On February 20, 2026, the U.S. Supreme Court ruled 6–3 in Learning Resources, Inc. v. Trump that IEEPA does not authorize the President to impose tariffs at all, a decision authored by Chief Justice Roberts holding that the statute's grant of authority to "regulate importation" does not include a power to tax. Within hours, the administration pivoted to Section 122 of the Trade Act of 1974, imposing a ten percent global surcharge with a CUSMA exemption; Canadian non-compliant goods saw their rate fall from 35 percent to 10 percent, and IEEPA tariff collection formally ceased at midnight on February 24, 2026.

That reprieve proved temporary. On July 20, 2026, President Trump signed three proclamations invoking Section 338 of the Tariff Act of 1930 — a provision no U.S. president had ever previously used — to impose 50 percent tariffs on Canadian goods in the dairy, alcoholic beverage, and motor vehicle sectors, on the theory that provincial and federal measures in each of those sectors discriminate against U.S. exporters. Crucially, these tariffs apply even to CUSMA-compliant goods and carry no expiry date. After a short administrative suspension, they took effect August 22, 2026, covering close to twenty billion U.S. dollars of Canadian goods across several hundred tariff lines, including machinery, electronics, textiles, wood products, cement, and furniture, well beyond the three sectors nominally at issue.

Canada's response followed within days. After negotiations broke down over the preceding weekend — Ottawa has stated plainly that Washington asked for too much and offered too little — Prime Minister Carney announced on August 22 that Canada would match the new U.S. measures dollar-for-dollar. The Department of Finance confirmed on August 25 a package of C$27.6 billion (roughly US$19.9 billion) in counter-tariffs, ranging from 15 to 50 percent, covering close to 700 U.S. product categories, effective September 8, 2026 — the Tuesday after Labour Day. The package is paired with a Canada Strong Diversification Fund, administered through the federal Strategic Response Fund, and a reported C$7.5 billion in direct support for affected workers and businesses. The conflict then expanded further: President Trump has separately threatened to raise tariffs on Canadian automobiles, trucks, and automotive parts to 50 percent, with a possible effective date of January 1, 2027.

II. The Legal Architecture of the Current Tariffs — and Why It Matters for the Provinces

This is the most consequential correction to earlier drafts of this assessment, and it changes the strategic calculus for every jurisdiction at this table. The tariffs Canada is now contending with are not the broad, single-source emergency measures of 2025. They are narrower, sector-specific, and legally untested.

Section 338 permits the President to impose duties where a foreign country is found to discriminate against U.S. commerce relative to other trading partners. It has never before been invoked in the near century since its enactment, and legal analysts on both sides of the border have flagged genuine open questions: whether the more specific and more recent Section 301 framework has effectively superseded Section 338's use for this purpose, and whether the International Trade Commission was required to investigate before any proclamation could issue. Litigation before the U.S. Court of International Trade is widely anticipated. This means the current 50 percent sectoral tariffs sit on considerably less stable legal footing than either side's public rhetoric suggests — a fact the Council should weight heavily in judging how long the present measures are likely to persist in their current form.

The layered result is a more complex tariff stack than in 2025. Canadian steel, aluminum, and copper remain subject to Section 232 tariffs at 50 percent, now running in parallel with, rather than displaced by, the Section 338 measures. A separate Section 301 forced-labour proceeding, concluded in July 2026, added a 10 percent tariff on Canadian goods not entered duty-free under CUSMA, layered on top of Section 338 where both apply. And Section 122's 10 percent global surcharge, imposed after the IEEPA ruling, itself lapsed on July 24, 2026, adding a further moving part. For the provinces, the practical implication is that the tariff environment premiers must plan around is not one number but several overlapping regimes, each resting on a different — and in the case of Section 338, largely unprecedented — statutory foundation, each independently exposed to litigation, and each capable of being modified, exempted, or escalated on separate timelines. This argues for provincial economic contingency planning that is scenario-based rather than built around a single assumed tariff rate.

III. The Council's Own Record: What Premiers Have Already Signalled

This Council does not need to be introduced to the stakes. At the July 21–23, 2026 summer meeting in Charlottetown, premiers met both virtually and in person with the Prime Minister specifically because of the escalating tariff threat, and the meeting communiqué placed Canada–U.S. relations, sovereignty and national security, and internal trade liberalization on the same agenda as healthcare and affordability — a sequencing that itself signals how directly this Council now treats the trade file as core provincial business.

The positions staked out in Charlottetown remain the reference points for this draft. Ontario Premier Doug Ford argued that Canada holds meaningful leverage through potash and oil exports and should be prepared to use it rather than continuing to absorb costs unilaterally. Manitoba Premier Wab Kinew observed that the escalation to tariffs on CUSMA-compliant goods had the effect of unifying Canada's premiers around a common external position. British Columbia Premier David Eby maintained that no agreement is preferable to a bad one, arguing that Canada's posture of resisting concessions made purely to close a deal has been vindicated over time. Prime Minister Carney, for his part, has repeatedly framed the federal-provincial relationship on this file as a "Team Canada" approach and has credited premiers with unlocking natural-resource and infrastructure projects that strengthen Canada's negotiating position.

The Council should treat this existing alignment as an asset to be preserved rather than a starting point to be renegotiated. As discussed in Section VII below, federal-provincial cohesion is itself a strategic variable in this conflict, and Washington has incentive to search for daylight between Ottawa and individual provinces, or between provinces with divergent sectoral exposure.

IV. The Fundamental Bayesian Game

The conflict is best modelled as a repeated bargaining game under incomplete information. The United States possesses greater aggregate economic power; Canada carries greater dependence on the U.S. market as a share of its own economy. But Canada holds several high-value strategic choke points — energy, electricity, critical minerals, agricultural commodities, metals, transportation infrastructure, integrated manufacturing, geographic proximity, and Arctic and Atlantic-to-Pacific corridors — that give it disproportionate leverage in specific sectors even where its aggregate bargaining power is weaker.

The game operates on three interacting levels. At the level of tariff bargaining, Washington raises tariffs, Canada retaliates, and Washington then decides whether to escalate further or return to the table. At the level of domestic political bargaining, President Trump must simultaneously satisfy protectionist constituencies, industrial workers, energy interests, inflation-sensitive consumers, border-state industries, and Republican legislators facing the 2026 midterms, while Prime Minister Carney must satisfy Ontario manufacturing, Alberta energy, Quebec industry, western agriculture, organized labour, consumers, and — critically for this Council — thirteen provincial and territorial governments with materially different sectoral exposure to the conflict. At the level of strategic restructuring, both federal governments must decide whether the relationship should eventually return to its pre-2025 equilibrium or whether a new North American arrangement should be built in its place.

This third level is the most consequential, and it is where provincial choices — on procurement, on interprovincial trade barriers, on energy infrastructure, on inbound investment screening — will do as much to shape the outcome as anything negotiated in Washington or Ottawa.

V. Canada's Changing Prior — and a Political Dimension the Council Should Not Discount

For decades, Canada's implicit operating assumption was that the United States might be a difficult and occasionally protectionist partner, but that the underlying North American economic architecture would remain fundamentally stable. That prior is being actively revised. The operating assumption increasingly informing federal and provincial planning is that the United States is willing to use market access itself as an instrument of coercion, and that Canadian economic dependence therefore constitutes a genuine strategic vulnerability rather than merely a commercial inconvenience.

This shift is not confined to elite policy circles; it is now a documented feature of Canadian public sentiment, and the Council should treat that sentiment as a strategic asset that increases Ottawa's credibility in sustained retaliation — while also recognizing its fragility. Reporting in late August 2026 disclosed leaked remarks by U.S. Vice President JD Vance disparaging Prime Minister Carney's negotiating posture at a private function, alongside continued references by President Trump to Canada as a "51st state" and a public suggestion that Lake Ontario be renamed. Wilbur Ross, who led U.S.–Canada trade negotiations during the first Trump administration, told reporters this week that the present round is materially harder to resolve than prior rounds precisely because Canadian public opinion has hardened against the United States on a scale he had not previously seen, and that any renewed initiative would likely have to originate from the Canadian side because the current administration is unlikely to move first.

Two implications follow for this Council. First, the erosion of Canadian goodwill toward the United States gives federal and provincial governments more political room to sustain retaliatory measures than would otherwise be available — a genuine asset in the bargaining game described above. Second, that same sentiment is a wasting asset if the conflict drags on long enough to generate acute cost-of-living pain in individual provinces; the Council's messaging and support programs should be calibrated with that time horizon in mind, particularly in jurisdictions with above-average exposure to affected sectors.

VI. The Automobile Sector: The Most Dangerous Node

Automotive trade remains the single most dangerous flashpoint in this conflict, and the record now available makes the mechanism more precise than earlier drafts could establish. The Section 338 motor-vehicle proclamation itself documents that U.S. vehicle exports to Canada fell by roughly 22 percent — from approximately US$25.9 billion to approximately US$20.3 billion — over the year following Canada's 2025 surtax on U.S.-origin vehicles, with Mexican, Japanese, South Korean, and German imports filling the resulting gap in the Canadian market. That figure is itself evidence for the strategic-interdependence thesis this assessment has advanced throughout: punitive measures in an integrated production system tend to redirect market share to third countries rather than simply reallocating it between the two disputants.

More than 200,000 Canadians work directly in the automotive sector, and roughly 500,000 depend on it directly or indirectly. The threatened escalation to 50 percent tariffs on Canadian vehicles, trucks, and parts, potentially effective January 1, 2027, would strike an integrated production system in which components cross the border repeatedly before a finished vehicle is sold. This creates a genuine dilemma for Washington: the more aggressively it targets Canadian automotive production, the more it risks disrupting the American automotive production with which Canadian output is interwoven. That is classic strategic interdependence, and it is the primary reason this assessment continues to regard a negotiated carve-out for integrated automotive supply chains as more likely than a full-scale automotive tariff war, even under the more escalatory scenarios below.

VII. Federal-Provincial Cohesion as a Strategic Asset

Canadian federal cohesion is itself a strategic variable in this conflict, and the Council should understand its own unity as a bargaining chip Washington cannot easily neutralize so long as it holds. If Washington can identify or exploit divergence between Ottawa and Alberta, between Ottawa and Ontario, or between provinces with differing sectoral exposure to the tariffs, Canada's aggregate bargaining power declines correspondingly. The federal government's continued emphasis on a Team Canada approach, and its efforts through 2026 to accelerate interprovincial trade liberalization and joint infrastructure investment, should accordingly be read as substantive components of Canada's external bargaining position rather than as domestic political rhetoric incidental to the trade file.

Alberta occupies a particular position in this equation. The federal government has placed sustained emphasis on keeping Alberta within a fully engaged Confederation and on developing the province's potential as an energy and agricultural powerhouse. Given the live question of Alberta's own relationship to federal energy and equalization policy, the Council has a direct interest in ensuring that provincial-federal disputes on those files do not become, or appear to become, exploitable seams in Canada's external negotiating position. The premiers' own Charlottetown discussions — where energy leverage was raised explicitly by Premier Ford — suggest the Council already understands this dynamic; the recommendation here is to formalize it.

VIII. Energy: Canada's Most Powerful and Most Dangerous Instrument

Canada continues to sell roughly 90 percent of its oil exports to the United States, according to figures cited by Trans Mountain's own leadership, which is precisely why diversification of export capacity has become an urgent strategic objective rather than a discretionary one. Canada's energy leverage is asymmetric in a specific way: withholding or taxing energy exports can inflict real cost on the United States, but it can inflict comparable or greater cost on Canada itself given the present lack of alternative export infrastructure. This is why an export levy, which preserves physical flows while shifting part of the economic burden onto U.S. purchasers and refiners, is likely to prove strategically superior to an outright supply reduction, should the Council or Ottawa ever consider using energy as a direct instrument of retaliation.

This dynamic has already begun to reshape the economics of west-coast pipeline expansion. Trans Mountain has argued publicly that the U.S. dispute strengthens the commercial and strategic case for expanding Canada's capacity to move oil to Asian markets. A Canada with greater Pacific energy access, expanded critical-mineral export and processing capacity, deeper European and Indo-Pacific trade relationships, and materially reduced dependence on a single export corridor would possess substantially greater bargaining power in any future negotiation with Washington. The trade war may therefore be inadvertently accelerating precisely the strategic diversification that economic coercion was intended to prevent — an outcome the Council should actively reinforce through provincial permitting, procurement, and infrastructure-investment decisions.

IX. Economic Seriousness: Real but Not Yet Systemic

Canada's second-quarter 2026 GDP grew at an annualized rate of roughly 3.3 percent, with exports up 3.6 percent and business investment recovering, providing a genuine — if temporary — cushion against the immediate shock of the August tariff escalation. That figure should not be read as evidence that the tariffs are without cost; the second-quarter data substantially predates the July 20 Section 338 proclamations and the August 22 escalation. The more relevant question for provincial fiscal planning is not whether the economy grew in the second quarter, but whether investment, employment, and export volumes can be sustained if the current tariff regime persists through 2027 without resolution.

The federal countermeasures package announced August 25 — C$27.6 billion in matching tariffs, a C$7.5 billion support envelope for affected workers and businesses, and the Canada Strong Diversification Fund routed through the Strategic Response Fund — represents the principal federal fiscal response available to provinces as they design complementary support of their own. Several provinces and territories have already moved independently on procurement restrictions, alcohol delisting, and toll adjustments targeting U.S. commercial traffic; the Council has an interest in monitoring these measures for consistency, since a patchwork of uncoordinated provincial retaliation risks both diluting the intended economic signal to Washington and creating friction with CUSMA obligations that Ottawa alone is positioned to manage.

X. The Monetary Policy Constraint

The Bank of Canada faces a genuine dilemma that limits how much macroeconomic relief provinces can expect from federal monetary policy. Trade restrictions weaken aggregate demand, which would ordinarily argue for a lower policy rate; but tariffs also raise input costs, which argues for caution on inflation grounds. A late-August survey of economists found consensus expectations that the Bank would hold its policy rate at 2.25 percent, with inflation running near the upper end of its target range and considerable uncertainty attached to the trade outlook. The practical implication for the Council is that provinces should not assume federal monetary accommodation will meaningfully offset tariff-related fiscal pressure in the near term; the mild stagflationary configuration now emerging — softer external demand alongside firmer import costs — constrains the Bank's room to manoeuvre in either direction.

XI. Strategic Scenarios, 2026–2028

Scenario A — Negotiated De-escalation (estimated probability: approximately 40 percent)

Both governments conclude that continued escalation produces diminishing political returns. Washington narrows or removes selected Section 338 measures, Canada reduces matching retaliation, and a modified CUSMA-adjacent framework emerges. This remains the single most likely individual outcome, though it would not restore the pre-2025 equilibrium in full.

Scenario B — Managed Trade War (estimated probability: approximately 35 percent)

Tariffs remain in force, but both sides avoid the most destructive escalatory steps. Automotive supply chains receive negotiated exemptions or phased treatment; energy continues flowing; negotiations resume intermittently without a comprehensive settlement. This could become the durable "new normal" for the relationship, and the Council should plan its medium-term fiscal and industrial strategy around this scenario as the base case.

Scenario C — Escalation into Structural Decoupling (estimated probability: approximately 20 percent)

Washington expands the tariff regime, most likely by carrying through on the threatened 50 percent automotive tariff; Canada retaliates against politically salient U.S. exports; energy becomes an active instrument in the bargaining game; investment migrates away from U.S.-dependent Canadian production; and Canada accelerates European and Indo-Pacific diversification in earnest. This would be economically costly in the near term but strategically transformative over a longer horizon.

Scenario D — Political Shock (estimated probability: approximately 5 percent)

A major discontinuous event — a severe recession, a dramatic electoral result, a leadership crisis on either side, or an extraordinary further escalation — changes the game abruptly. Low probability, potentially high consequence, and not meaningfully plannable in advance beyond maintaining fiscal and institutional resilience.

The four scenarios above, and the deliberate preservation of an off-ramp in each, reflect this uncertainty directly: rather than betting solely on the modal outcome, this assessment treats the possibility of a structural break as itself uninsurable within a single prior, and hedges accordingly.

XII. The 2026 U.S. Midterms as a Bayesian Signal

An important clarification belongs in this draft: the 2026 midterm elections cannot themselves produce a change in the U.S. presidency. They determine control of Congress; the next presidential election is in November 2028. The midterms nevertheless matter as an information event. If Republicans suffer significant losses, congressional incentives to distance the party from tariff-driven damage to manufacturing, agriculture, and consumer prices increase, and Canada's posterior probability that Washington will eventually moderate its trade strategy should rise accordingly. A strong Republican midterm performance would have the opposite effect, strengthening the administration's bargaining credibility and requiring Canada to revise its expectations of continued pressure upward.

Even a favourable midterm outcome for Democrats, however, would not by itself restore the pre-2025 relationship, and a Democratic presidential victory in 2028 — currently an open strategic possibility rather than a base-case assumption — would inherit a materially altered starting point: reshaped supply chains, expanded Canadian trade diversification, hardened Canadian public sentiment, and a more protectionist American electorate generally. The probability of a complete return to the old relationship is accordingly much lower than the probability of a genuinely improved but structurally different one.

XIII. The Deepest Finding: A Bayesian Learning Process Under Knightian Pressure

The most consequential long-run effect of this conflict may not be tariff revenue or any single quarter's GDP print. It is a Bayesian learning process, on both sides, in the De Finetti–Savage sense: each retaliatory measure, court ruling, and electoral signal is treated as an exchangeable draw, licensing an underlying belief about Washington's "type" that should, if the process is genuinely stationary, concentrate over time. Canada is learning to hold a more diffuse prior over what was once treated as bounded commercial risk — economic dependence on a single partner is being repriced as a source of deeper, harder-to-quantify geopolitical exposure. The United States is learning that economic coercion against Canada generates retaliation capable of damaging integrated American industries, particularly automotive manufacturing. Businesses on both sides of the border are learning that CUSMA protection is not, on its own, sufficient to guarantee long-term certainty, since Section 338 tariffs apply even to CUSMA-compliant goods. And provincial governments are learning — through the Section 338 proclamations, which explicitly cite provincial alcohol and procurement measures as triggering conduct — that their own policy choices are now direct inputs into a bilateral bargaining game, not purely domestic matters.

This convergence is not guaranteed. It presumes the underlying process is exchangeable — that Washington's actions are noisy draws around some stable disposition rather than evidence of a genuine structural break in American trade policy. If the latter is true, the representation theorem's convergence guarantee does not hold, and Canada's posterior may fail to concentrate at all, or concentrate on the wrong parameter. That possibility is itself the strategic risk this report has emphasized throughout: not that Canada updates the wrong way, but that there may be nothing stationary left to learn.

XIV. Strategic Implications Specifically for the Council of the Federation

Canada's optimal collective strategy is neither unconditional accommodation nor maximal retaliation; it is selective, coordinated pressure combined with accelerated diversification, and provinces have direct instruments available on each front. This Council should consider:

  • Maintaining a unified public position with Ottawa, recognizing that visible federal-provincial or interprovincial division is the single most exploitable seam in Canada's bargaining position.

  • Coordinating provincial procurement and retaliatory measures (alcohol delisting, contract restrictions, toll adjustments) through the Council rather than unilaterally, to avoid diluting their intended signal or creating avoidable CUSMA friction.

  • Accelerating the removal of remaining interprovincial trade barriers, both as a direct economic offset to lost U.S. market access and as a demonstration of Canadian economic seriousness to outside observers.

  • Treating energy and critical-mineral infrastructure — west-coast export capacity, interprovincial transmission, critical-mineral processing — as shared national-security infrastructure warranting expedited joint federal-provincial permitting.

  • Calibrating provincial worker and business support programs to a multi-year time horizon, given that Section 338's legal durability is genuinely uncertain and litigation timelines at the Court of International Trade are unlikely to resolve the underlying dispute quickly.

  • Preserving, rather than foreclosing, an eventual off-ramp for Washington — avoiding rhetoric that frames the objective as defeating the United States rather than changing its calculation of the costs of coercion.

XV. Strategic Implications for Ottawa and Washington

For the federal government, the logic set out above argues for maintaining targeted, reciprocal countermeasures rather than indiscriminate escalation; protecting the most deeply integrated supply chains, above all automotive, from unnecessary disruption; keeping energy flowing absent an extreme strategic provocation; and using CUSMA and available international legal mechanisms wherever they offer genuine leverage.

For Washington, the strategic logic is symmetric. If the underlying objective is genuine economic security rather than short-term political signalling, an open-ended tariff war with Canada is difficult to justify on its own terms: Canada supplies the United States with energy, metals, agricultural products, electricity, industrial inputs, and critical minerals that a more adversarial relationship would put at risk. The distinction between legitimate, narrowly targeted sectoral disputes and the systemic erosion of North American economic integration is one the administration has not yet drawn with any clarity, and the unprecedented, legally untested character of the Section 338 authority now in use raises the odds that courts, rather than negotiators, ultimately force that distinction to be made.

XVI. Conclusion: Is This a Serious Problem?

Yes — but the most serious problem is not the current tariff bill, and it is not any single number in this report. It is the erosion of predictability itself. For seventy years, North American economic integration rested on the shared expectation that political disagreement would not fundamentally sever commercial interdependence. That expectation has weakened, and the evidence canvassed in this draft — from the unprecedented use of Section 338, to the documented hardening of Canadian public sentiment, to premiers' own public statements on leverage and unity — indicates the weakening is now a settled fact of the relationship rather than a temporary condition to be waited out.

At the same time, Washington is discovering that superior aggregate economic power does not translate automatically into unlimited coercive power over an integrated trading partner, particularly in automotive manufacturing and energy. The result is a genuine Bayesian strategic transition: the United States is testing whether Canada will update toward accommodation, and Canada — provinces very much included — is testing whether the United States will update toward restraint. The central strategic lesson for this Council is that Washington may be able to impose tariffs on Canada more easily than Canada can impose comparable costs on the United States, but it cannot impose those tariffs without altering Canada's future strategic preferences, including the preferences of the provinces and territories represented at this table. Canada may be absorbing greater short-run economic cost while gaining greater long-run strategic autonomy — and how deliberately, and how unitedly, that autonomy is built over the next twelve to twenty-four months is now substantially in this Council's own hands.

Discipline, Not a Decision 


A Bayesian/Game-Theoretic Reading of Kevin Warsh's Jackson Hole Address, the Corrected Empirical Record, and a 2026–2030 Reaction-Function Framework 


Revised and expanded analysis — August 28, 2026




Preface to the Revision

The version of this paper prepared before Chairman Warsh delivered his remarks anticipated, correctly, that he would resist conventional forward guidance while still communicating a great deal about his priorities. What the earlier draft could not know is precisely how he chose to resolve that tension, because he chose to resolve it more starkly than anticipated: rather than replacing calendar guidance with an implicit reaction function, Warsh explicitly declined to offer one, telling the audience at the Kansas City Fed's Jackson Hole Economic Policy Symposium that a published rule for policy "works better in theory than in practice," and that the Federal Reserve's models are not yet reliable enough to bind the Committee to one. His own formulation was that he stands "committed to a discipline, not to a decision."

This revision corrects that record, incorporates the market's and the data's response through the close of trading on August 28, 2026, and reframes the whole argument in explicitly Bayesian and game-theoretic terms, including a formal reaction-function framework spanning Warsh's term through 2030 and probability-weighted scenarios for inflation, the September 15–16 Federal Open Market Committee decision, Treasury yields, and the dollar. All data below are drawn from the Federal Reserve, the Bureau of Economic Analysis, the Bureau of Labor Statistics, the U.S. Treasury, and contemporaneous wire and financial reporting, cited by source and date throughout, with full references at the end.


I. What Warsh Actually Said: The Corrected Record

Warsh's address, titled "In Our Time" and delivered at 10:00 a.m. Eastern time on Friday, August 28, at the Kansas City Fed's symposium in Moran, Wyoming, was his first appearance at Jackson Hole as chair, and only his second major public statement on monetary policy since the Federal Open Market Committee's July 28–29 meeting, at which the Committee held its target range at 3.50 to 3.75 percent over three dissents in favor of a quarter-point increase — the first instance of three same-direction dissents on the Committee in roughly a decade (CNBC, Kiplinger).

Two features of the speech matter most for the analysis that follows. First, Warsh explicitly rejected both forward guidance and a published reaction function, arguing that a rule-based commitment to a specific interest-rate path "works better in theory than in practice" because the Fed's understanding of the economy's underlying structure is still incomplete. He framed this not as evasion but as candor about the limits of the Committee's models, while promising that he and his colleagues will work over his term to "construct more reliable models and more robust rules to guide policy decisions" (CNBC, Bond Buyer). Second, and in some tension with that restraint, Warsh was unambiguous about his diagnosis of the current conjuncture: inflation is too high, the labor market is at full employment, and financial conditions are not restrictive. On inflation specifically, he stated that "while this summer's PCE and CPI readings were better than expected, they do not tell me that underlying trends have meaningfully improved," and that "we must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do" (CNBC). He separately said he "would be hard pressed to describe broad financial conditions as restrictive" (Bond Buyer).

Warsh grounded that judgment in figures he cited directly: personal consumption expenditures (PCE) inflation running at 3.7 percent over the past twelve months and at a 4.1 percent annualized pace over the past six months — a marked acceleration in the underlying trend relative to the trailing-year figure — against a 2 percent objective he repeatedly called "a firm, fixed target" (Benzinga, Bloomberg). He also devoted a substantial section of the speech, under the heading "Preparing for Future Policy Conjunctures," to artificial intelligence, describing business capital expenditure in equipment and intangibles as growing at roughly 9 percent over the past four quarters — its fastest pace since 2021 — with more than half of that growth attributable to the AI buildout; S&P 500 profits up more than 20 percent over the past year; corporate credit spreads near the low end of their historical range with strong issuance; and annualized token sales at the two leading AI labs exceeding $100 billion, up more than 500 percent in a year (Federal Reserve, Euronews, Decrypt).

The upshot is that the earlier draft's characterization of Warsh as having replaced calendar guidance with a "highly recognizable policy reaction function" overstated what he did. He did not commit to a rule. What he offered instead was closer to what game theorists would call a stated preference ordering without a committed strategy: a clear statement of what outcome he wants (inflation convincingly returning to 2 percent), combined with a refusal to specify the policy function that maps future data realizations into future rate decisions. That combination — clear objective, opaque function — is the single most important structural fact about the Warsh Fed, and it is the organizing problem for the rest of this analysis.


II. The Market's Answer: Warsh Cannot Escape the Reaction-Function Problem by Declining to State One

The market treated the speech as decisively hawkish despite Warsh's explicit refusal to guide. According to CME Group's FedWatch tool, the probability traders assigned to a 25-basis-point hike at the September 15–16 meeting jumped from roughly 34–35 percent on Thursday, August 27, to approximately 57.5 percent by Friday's close — essentially a coin flip that tilts toward tightening (CNBC). Prediction markets moved even further: Polymarket odds of a 2026 rate hike rose to as high as 69 percent, up from the mid-50s the day before, while Kalshi traders assigned roughly 48 percent odds to a September hike specifically (Benzinga, CNBC). The policy-sensitive two-year Treasury yield rose approximately 8 to 9 basis points to about 4.31–4.32 percent, its highest level since late July, while yields further out the curve were comparatively little changed — evidence, discussed further below, that the market repriced near-term policy rather than the long-run inflation regime (CNBC, Benzinga, Investing.com). The U.S. Dollar Index gained roughly 0.4 to 0.5 percent to around 99.50, putting the dollar on pace for a weekly gain of nearly 1 percent that erased the prior week's "debasement trade" losses (FXStreet, Investing.com). Equities were more ambivalent: the S&P 500 slipped modestly on the day even as it closed out a positive week overall, a sign that investors absorbed the hawkish signal without a disorderly repricing of risk assets (CNBC).

This is the empirical core of the paradox this paper is built around, and the corrected record sharpens rather than dissolves it. Warsh said, in substance, that he will not tell markets his reaction function because the Fed's models are not good enough to bind him to one. Markets responded by constructing a reaction function for him anyway, inferring from his inflation diagnosis and his "work to do" language that a September hike is now more likely than not priced at even money. In Bayesian language, Warsh supplied a strong signal about his prior beliefs — that the current data represent adverse news relative to the Fed's inflation objective — without supplying the likelihood function that would map future data into a specific policy response. Markets filled that gap themselves, using their own model of Warsh's reaction function, which is precisely the "hall-of-mirrors" dynamic Warsh has warned against: the Fed's words shape market prices, and those prices will now be read by the Fed, and by outside observers, as if they were an independent read on the economy, when a meaningful share of the move is mechanically downstream of the chairman's own rhetoric.

The strategic logic here is closer to a signaling game than to conventional forward guidance. Warsh's speech functions as a costly signal of type — a hawkish policymaker revealing information about his own preferences and tolerance for inflation risk — without committing to an action rule contingent on future states of the world. Markets, as rational Bayesian receivers, updated their posterior over Warsh's type (more hawkish than previously priced) and, absent an explicit reaction function, substituted the modal type-consistent action (a hike) as their best guess of what a hawkish Warsh does when data are ambiguous. That substitution is exactly what a game-theoretic treatment would predict when a principal reveals type but withholds strategy: the agents she is signaling to will impute the strategy most consistent with the revealed type. Warsh's stated goal of a "quieter" Fed is, on this reading, unlikely to be achieved by withholding reaction functions alone, because market participants will construct and price an inferred reaction function regardless of whether the Fed publishes one. The chairman's own words on this point—describing his approach as a "discipline, not a decision"—capture the intended posture, but the market's job is to price decisions, and it will use whatever discipline it can observe as a proxy for the decision rule.


III. The Corrected Data Record Through August 28, 2026

On inflation, the July Personal Consumption Expenditures report, released by the Bureau of Economic Analysis on August 26, showed headline PCE inflation at 3.7 percent year over year and core PCE (excluding food and energy) at 3.3 percent, both firmer than consensus expected; the monthly core reading has now printed 3.3, 3.4, 3.3, and 3.3 percent in April through July, which is the four-month stall in underlying disinflation that Warsh's six-month annualized 4.1 percent figure was designed to highlight (Bureau of Economic Analysis; Yahoo Finance/BEA data). The July Consumer Price Index, released by the Bureau of Labor Statistics on August 12, showed headline CPI up 3.4 percent year over year and core CPI up 2.5 percent, both a tenth of a point softer than June, with shelter accounting for roughly two-thirds of the monthly increase and energy prices volatile amid the ongoing Middle East conflict (Bureau of Labor Statistics; CNBC; NBC News).

On employment, the July jobs report showed nonfarm payrolls declining by 23,000 — a sharp reversal from the roughly 34,000 average monthly gain over the prior year — while the unemployment rate held at 4.1 percent (Bureau of Labor Statistics; Wichita Liberty/BEA-BLS synthesis). A separate annual benchmark revision to the payroll count, timed to coincide with the run-up to Jackson Hole, registered a further modest downward adjustment to the level of employment, reinforcing the sense among several FOMC participants that labor-market momentum has cooled even as the unemployment rate itself remains low (FXStreet, "Forex Today"). Warsh's own reading, delivered in the speech, was that the labor market remains "consistent with full employment," even as he called the inflation side of the mandate "more concerning" — an explicit statement of asymmetric concern across the dual mandate that matters for the reaction-function reconstruction in Section VI (Investing.com).

On financial conditions, Warsh's own remarks — not the earlier draft's secondhand characterization — are the best evidence: he told the audience that corporate credit spreads are "near the low end of their historical averages" with strong issuance volumes, that business capital expenditure in equipment and intangibles is growing near a five-year high, and that S&P 500 profit margins are "quite elevated, relative to history" (Federal Reserve transcript). Those are Warsh's own words, not an outside inference, and they support his conclusion that policy is not obviously restrictive by the normal channels through which monetary tightening is supposed to bite.

On the fiscal side, the Treasury's regular August refunding, announced by the Department earlier in the month, will raise $125 billion through new three-year, ten-year, and thirty-year issuance — $58 billion, $42 billion, and $25 billion respectively — to refund roughly $96.3 billion of maturing debt, raising about $28.7 billion in new cash (U.S. Department of the Treasury). More consequential for the fiscal-monetary interaction this paper emphasizes was a surprise announcement on August 19: Treasury Secretary Scott Bessent said the Department would at least double the size of its buyback operations in longer-dated nominal coupon securities — the 10-to-20-year and 20-to-30-year sectors — from a $2 billion to a $4 billion maximum per operation, beginning September 9 and running through the November 4 refunding (U.S. Department of the Treasury; CNBC; Council on Foreign Relations). Treasury officials have also indicated Bessent could draw on a Treasury General Account that has been built up to roughly $950 billion to fund a larger buyback program if he judges conditions warrant it (CNBC). Reuters and CNBC reporting both describe this as an unusual departure from Treasury's long-standing "regular and predictable" issuance doctrine, prompted by a multi-week "buyers' strike" in the long end of the curve; the initial announcement briefly pushed the ten-year yield down 5.7 basis points and the thirty-year down 9 basis points before skepticism about Bessent's actual firepower reasserted itself (CNBC).

On energy and geopolitics, the conflict between the United States, Israel, and Iran remains the through-line affecting the inflation data Warsh is reading. Brent crude has risen more than 38 percent in 2026 amid recurring disruption to transit through the Strait of Hormuz, with national average U.S. gasoline prices oscillating in the $4.00-to-$4.10-per-gallon range over the summer (CNBC/AAA data; TradingEconomics). The July FOMC minutes record that "developments over the intermeeting period were influenced by the conflict in the Middle East," that oil prices rose as a result, but that "inflation compensation moved little in response to higher oil prices" — evidence the Committee itself has already begun using to distinguish a supply-side energy shock from a more troubling de-anchoring of inflation expectations (Federal Reserve, FOMC Minutes, July 28–29, 2026).


IV. The Forward-Guidance Paradox, Restated

The original critique of Warsh — that his rejection of forward guidance was itself a form of forward guidance — required amendment once his actual remarks were available, but the underlying insight survives in a sharper form. Warsh did not, as the earlier draft assumed, construct an implicit rule. He constructed something game theorists would recognize as a partially separating signal: enough information to reveal that his type is hawkish relative to market expectations, but not enough to specify the mapping from future data to future action. The paradox is therefore not that his silence was itself guidance — it demonstrably was not, in the narrow sense of specifying a rule — but that his silence was informationally indistinguishable from guidance in its market effect, because markets do not require an explicit rule to trade a hawkish signal; they only require a credible update to their estimate of the chairman's reaction function, which his tone, his selective statistics, and his "work to do" language supplied in abundance.

This distinction matters for how the framework should be built going forward. A model of "Warsh forward guidance" that treats his speech as announcing a rule would be a category error; what should instead be modeled is Warsh as a Bayesian type whose preferences are becoming better known to the market with each communication, while his policy function — the mapping from data to decisions — remains deliberately unspecified and is instead inferred, meeting by meeting, from incoming data and from the chairman's evolving rhetoric. That is a fundamentally different — and, in an important sense, more honest — way to run a central bank than either Powell-era "data dependence" rhetoric or classical Taylor-rule commitment. But it is not obviously more stabilizing, because it pushes the burden of constructing the reaction function onto the market itself, which will do so noisily and with its own behavioral biases, including a tendency to overweight the most recent, most quotable line from the chairman.


V. The Lucas Critique, Applied to Central-Bank Communication Itself

Warsh's own instinct — that publishing a rule invites a form of the Lucas critique, in which private agents adapt their behavior to the announced rule and thereby undermine the historical relationships the rule was built on — is defensible in principle. Historical estimates of the relationship between the federal funds rate and inflation outcomes were generated under a regime of increasingly explicit forward guidance; there is no guarantee those relationships are stable if the Fed reverts to a discretionary regime, or vice versa. But Warsh's proposed solution — discretion without a stated rule — does not escape the deeper problem, because market expectations do not require an official rule to form; they only require data and communication, both of which Warsh continues to supply liberally. The practical question this paper's framework must answer is therefore not guidance versus no guidance, but how the Fed can supply enough structure to keep market-inferred reaction functions anchored to fundamentals, rather than to the volatility of the chairman's most recent public appearance.


VI. A Formal Reaction-Function Reconstruction, 2026–2030

Because Warsh has declined to publish a rule, any reaction function attributed to him is necessarily a reconstruction from revealed preference rather than a stated commitment, and it should be treated as a probabilistic model of his behavior rather than a description of Fed policy. Four structural features of the reconstructed function can be read directly out of the evidence in Sections I through III, described here in words rather than as an explicit formula, consistent with this paper's standing convention of avoiding mathematical notation.

First, Warsh weights the inflation leg of the dual mandate more heavily than the employment leg at the current juncture, and has said so explicitly by calling inflation "more concerning" while describing the labor market as consistent with full employment. A reconstructed Warsh function should therefore treat further softening in payrolls as a much weaker trigger for easing than persistent core PCE readings above roughly 3 percent would be as a trigger for tightening — an asymmetric, inflation-dominant reaction function, at least for as long as unemployment stays near its current low level.

Second, Warsh privileges the level and trend of underlying, rather than headline, inflation, and has revealed a preference for six-month annualized core measures — hence his choice to cite the 4.1 percent six-month PCE figure rather than the more favorable twelve-month reading — as the metric most likely to move him toward tightening. A reconstructed function should weight the most recent two to three months of core data more heavily than the trailing-twelve-month comparison the earlier draft of this paper implicitly used.

Third, Warsh treats financial-conditions looseness — tight credit spreads, strong equity performance, robust capital expenditure — as evidence that the current policy rate is not doing much restraining work, independent of what the federal funds rate itself is doing. This is consistent with a policymaker who would be willing to raise rates even without further inflation deterioration, on the theory that the existing rate has simply not been transmitted into tighter conditions. A reconstructed function should therefore include a financial-conditions term that can push toward tightening even when the inflation and employment data are merely stable rather than worsening.

Fourth, and this is the most novel feature relative to the pre-Warsh Fed, artificial intelligence enters the reconstructed function as a source of genuine two-sided uncertainty about the economy's noninflationary growth capacity rather than as a straightforward hawkish or dovish input. Warsh's own language — describing AI as a potential "new factor of production" whose productivity effects the Fed "cannot answer yet" — suggests he is deliberately keeping this variable out of the near-term reaction function while a new Fed task force on productivity and jobs examines it, with findings not expected before year-end and explicitly stated to have no bearing on near-term decisions (Euronews).

Extending this reconstruction across Warsh's likely term — a chairmanship that began in May 2026 and would run, on the standard four-year term, into 2030 — requires treating the four features above as reasonably stable priors about Warsh's type, updated meeting by meeting as new data arrive, rather than as a fixed rule. The most defensible forward-looking statement is therefore not a prediction of specific rate levels through 2030, but a statement about the character of the regime: a Fed that will remain inflation-dominant in its revealed weighting for as long as unemployment stays in the low fours, that will resist publishing a rule even as its five internal task forces (on communications, balance-sheet policy, data, productivity and jobs, and inflation frameworks) report out through late 2026 and into 2027, and that will treat each Jackson Hole address, each FOMC statement, and each significant Warsh public appearance as a fresh, freshly-informative signal about his evolving reaction function rather than as confirmation of a previously announced path — precisely because he has foreclosed the latter.


VII. Probability-Weighted Scenarios: The September 2026 FOMC Decision

Treating the September 15–16 meeting as the first live test of the reconstructed reaction function, three scenarios can be assigned rough, evidence-consistent probability weights as of August 28, 2026, understanding that these weights will move with each subsequent data release, most importantly the August employment report and the August CPI report, due September 11, just days before the meeting.

The modal scenario, carrying perhaps 45 to 55 percent weight given the roughly 57.5 percent CME-implied probability of some hike but the absence of any Warsh commitment, is a 25-basis-point increase to a 3.75-to-4.00 percent target range, delivered alongside an unusually candid Summary of Economic Projections given that September is one of the Fed's four dot-plot meetings. This outcome is most likely if the August employment report shows stabilization rather than further deterioration and if August CPI or the incoming core PCE trend fails to show the deceleration Warsh said he has not yet seen. A second scenario, carrying perhaps 35 to 40 percent weight, is a hold at 3.50 to 3.75 percent accompanied by an explicitly hawkish statement and dot plot signaling a high probability of tightening at the October or December meeting — in effect, the Committee using the statement language rather than the rate itself to manage expectations, consistent with Warsh's general preference for judgment over pre-commitment. This scenario becomes more likely if the labor-market data deteriorate further, giving the more dovish members of the Committee, several of whom dissented toward easing earlier in the cycle before the Iran-related energy shock complicated that view, more room to argue for patience. A third, low-probability scenario, weighted at perhaps 10 to 15 percent, is a hold with no clear hawkish signal, which would most likely follow either a sharp downside surprise in employment or a ceasefire-driven collapse in oil prices materially undercutting the inflation case Warsh built his speech around; given the fragile, on-and-off character of the Iran conflict, an abrupt de-escalation cannot be ruled out and would materially soften the near-term inflation read Warsh emphasized (Federal Reserve, FOMC Minutes; CNBC).


VIII. Probability-Weighted Scenarios: Inflation Through Year-End

On core PCE inflation, the most probable path over the next two prints, carrying a weight of roughly 50 percent, is continued stagnation in the 3.2-to-3.4 percent range, consistent with the flat four-month run already observed and with an energy shock that is real but, per the July FOMC minutes, not yet visibly bleeding into inflation compensation. A second scenario, weighted at roughly 25 to 30 percent, is a further modest acceleration toward or above 3.5 percent, most likely to occur if the six-month annualized trend Warsh emphasized proves to be the leading indicator rather than a statistical artifact, or if a renewed escalation in the Iran conflict pushes oil and gasoline prices materially higher than the already-elevated levels observed through the summer. A third, more optimistic scenario, weighted at roughly 20 to 25 percent, is a resumption of disinflation toward 3.0 percent by year-end, most plausible if shelter costs — which have accounted for roughly two-thirds of recent monthly CPI gains — continue to ease as they showed some signs of doing in the July CPI report, and if energy prices stabilize or retreat on a durable, rather than temporary, reduction in Middle East tensions.


IX. Probability-Weighted Scenarios: Treasury Yields and the Dollar

For the two-year Treasury yield, now trading near 4.31 to 4.32 percent, the most probable near-term path, weighted at roughly 50 percent, is a range-bound drift between roughly 4.20 and 4.45 percent through the September meeting, with the outcome of that meeting itself the dominant catalyst for a breakout in either direction. A hawkish September outcome — either an actual hike or an explicitly hawkish hold — would be consistent with a push toward or above 4.50 percent, a scenario this paper weights at roughly 30 percent given the market's already-substantial repricing since Friday. A dovish surprise, weighted at roughly 20 percent, would likely pull the two-year back toward 4.00 to 4.10 percent. Longer-dated yields are governed by a more genuinely two-sided process, because the ten-year and thirty-year sectors are now simultaneously exposed to Warsh's inflation signaling and to Bessent's buyback program, whose first operations begin September 9. Because the two forces point in different directions — hawkish Fed signaling pushes long yields up through higher expected short rates and inflation compensation, while larger Treasury buybacks push long yields down through reduced net supply and improved liquidity — the most probable outcome for the ten-year, weighted at perhaps 45 percent, is a comparatively contained trading range relative to the more volatile two-year sector, with the two forces substantially offsetting one another through the fall. A scenario in which Bessent's buybacks prove insufficient relative to financing needs, allowing the fiscal-supply effect to dominate and push the ten-year higher despite the offsetting purchases, carries perhaps 30 percent weight, consistent with Evercore ISI's public skepticism that the buyback program, at $4 billion per operation against roughly $5.5 trillion in outstanding 20- and 30-year debt, has the scale to durably move the market (CNBC). A scenario in which the buyback program, potentially reinforced by draws on the nearly $950 billion Treasury General Account, meaningfully compresses term premium carries the remaining roughly 25 percent weight.

For the dollar, now at a two-week high near 99.50 on the Dollar Index after Friday's roughly half-percentage-point gain, the modal scenario, weighted at roughly 45 percent, is continued firmness into September as the market keeps a hawkish Fed repriced, particularly if the European Central Bank proceeds with a widely-expected September rate increase of its own — which would partially offset dollar strength through relative-rate channels — and if the Bank of England remains constrained by weaker growth expectations (FXStreet, Yahoo Finance). A scenario in which the dollar gives back a substantial share of Friday's gains, weighted at roughly 30 percent, would most likely follow either a September hold or data between now and the meeting that undercut the inflation narrative. A tail scenario, weighted at roughly 25 percent, involves a return of the "debasement trade" — the broad skepticism about U.S. fiscal sustainability and Fed independence that pressured the dollar and lifted gold in the week before Jackson Hole — reasserting itself if Bessent's fiscal interventions are read by markets as evidence of Treasury pressure on the Fed rather than as ordinary debt management, a risk this paper's fiscal-dominance discussion in Section X treats as understated in the original draft.


X. Fiscal Dominance and the Treasury-Fed Interface, Updated

The original draft's distinction between Treasury debt issuance and central-bank money creation remains analytically correct and worth preserving: Bessent's operations do not mechanically expand the money supply in the way the earlier, cruder critique implied. But the empirical record through August 28 makes the fiscal-monetary interaction considerably more concrete and more urgent than the original draft's abstract treatment suggested. Bessent's decision to announce a surprise doubling of long-bond buybacks on August 19 — bypassing the normal quarterly refunding channel for such changes, according to Treasury officials themselves — and his acknowledgment on CNBC that operations could run even larger than the new stated minimum, both signal an activist Treasury willing to intervene directly in the long end of the curve at the same time the Fed chair is signaling tighter near-term policy (CNBC). Citi's own commentary ahead of the Jackson Hole speech explicitly flagged that investors would be watching "whether his views would align with those of Treasury Secretary Scott Bessent," and that greater apparent coordination could itself compress long-term yield volatility — precisely the kind of signal a Bayesian market participant should treat as information about the joint fiscal-monetary regime, not simply about the Fed in isolation (yournews.com/Citi commentary).

This is the clearest evidence yet that the fiscal-dominance risk this paper's framework must price is not a distant, hypothetical concern but an active, live dynamic: a Treasury running a near-$1 trillion cash buffer and an enlarged buyback program, operating alongside a Fed chair who has explicitly declined to coordinate his communications with the Treasury's own signals — Seeking Alpha's pre-speech commentary noted analysts did not expect Warsh to comment on Bessent's buyback plans at all, for fear of appearing "political" (Seeking Alpha) — is a textbook setting for the market to misread a debt-management signal as a monetary signal, or vice versa, exactly the confusion Section IX's yield-scenario analysis above is built to price around rather than assume away.



XI. AI as a Genuine Two-Sided Bayesian Variable

Warsh's own numbers substantially strengthen, rather than merely restate, the AI section of this paper's original analysis. A four-quarter capital-expenditure growth rate of roughly 9 percent, the fastest since 2021 and more than half attributable to AI infrastructure; S&P 500 profit growth above 20 percent; and annualized AI token sales at the two largest labs exceeding $100 billion, up over 500 percent in a year, together describe an investment boom of a scale that plausibly does shift the economy's noninflationary growth capacity, exactly as the productivity-shock hypothesis in the original framework proposed (Federal Reserve; Decrypt; Euronews). But the same data are equally consistent with the asset-price-boom hypothesis: concentrated gains, a single chipmaker's ability to both supply and finance a large share of its own customer base, and reporting that a large majority of generative-AI companies remain commercially unsuccessful even as capital continues to pour into the sector, all point toward the possibility that today's elevated profit margins and tight credit spreads partly reflect speculative enthusiasm rather than realized productivity gains (Decrypt). Warsh's own posture — creating a dedicated task force on productivity and jobs, explicitly stating its findings will not affect near-term policy, and continuing to "watch the change in growth rates, the second derivative" of both capital expenditure and earnings — is itself consistent with a policymaker treating this as a genuinely unresolved Bayesian hypothesis rather than a settled input, which is the correct posture and one this paper's framework should adopt as well, resisting the temptation to resolve the AI question in either direction before the evidence supports doing so.


XII. Energy, Iran, and the Second-Round Inflation Question

The Iran-Israel-U.S. conflict remains the paper's most important recurring geopolitical variable and continues to complicate the inflation read at the center of Warsh's speech. Brent crude's more than 38 percent rise in 2026, driven by recurring disruption to Strait of Hormuz transit, and national gasoline prices that have oscillated near $4.00 to $4.10 per gallon through the summer, are the proximate cause of the energy volatility embedded in both the CPI and PCE releases discussed above (CNBC/AAA; TradingEconomics; NBC News). The July FOMC minutes' explicit finding that inflation compensation "moved little" despite the oil-price increase is the single most important piece of evidence available to the Committee that this remains, for now, a first-round supply shock rather than a second-round de-anchoring of expectations — precisely the distinction this paper's Bayesian framework treats as the central open question for energy-driven inflation (Federal Reserve, FOMC Minutes). The appropriate policy variable, as in the original draft, remains the probability that the energy shock becomes embedded in wage- and price-setting behavior rather than the oil price itself, and the July minutes' finding is evidence — not yet conclusive, but genuinely informative — that this probability remains low as of late July, a reading the Committee will need to revisit before September 16 given the conflict's continued, unresolved character.


XIII. Final Assessment

The corrected record sharpens rather than resolves the central tension this paper set out to examine. Kevin Warsh did not, as initially reported and analyzed, construct an implicit reaction function to replace explicit forward guidance. He explicitly declined to construct one at all, on the stated grounds that the Fed's models remain too unreliable to bind the Committee to a rule, while nonetheless communicating an unmistakable diagnosis — inflation too high, labor market fully employed, financial conditions too loose — that markets have priced with nearly as much conviction as if he had announced a rule outright. The gap between what Warsh intended to communicate and what markets extracted from his remarks is itself the most important data point in this analysis, because it demonstrates that a central bank cannot escape the burden of managing expectations simply by declining to publish a formal reaction function. Markets will construct one regardless, from whatever signal is available, and the quality of that market-constructed function — whether it tracks the Fed's true, still-undisclosed priorities or diverges from them — is now substantially outside the Fed's direct control.

Four structural features of the Warsh Fed, reconstructed here from revealed preference rather than stated commitment, should anchor expectations through the remainder of his term: an inflation-dominant weighting of the dual mandate for as long as unemployment stays low; a preference for near-term, six-month annualized core inflation measures over trailing-twelve-month comparisons; a willingness to treat loose financial conditions as an independent argument for tightening; and a deliberately unresolved, two-sided treatment of artificial intelligence as a productivity variable that could shift the neutral rate in either direction. Layered onto this reconstructed monetary reaction function is an increasingly assertive fiscal actor — a Treasury Secretary now conducting surprise interventions in the long end of the Treasury curve with a nearly $1 trillion cash buffer behind him — whose signals markets must learn to separate from the Fed's own, and an unresolved geopolitical energy shock whose second-round inflation consequences remain, on the best evidence available through July, contained but not resolved.

The September 15–16 FOMC meeting is therefore best understood not as a single up-or-down test of Warsh's credibility, but as the first of what will be a long sequence of Bayesian updates, in which each employment report, each inflation print, each Bessent buyback operation, and each subsequent Warsh public appearance further refines — without ever fully revealing — the reaction function this paper has attempted to reconstruct. The discipline Warsh has committed to is real. Whether it produces better decisions than the forward guidance it replaces will not be knowable from this speech alone. It will be knowable only from the pattern of decisions the Committee actually makes as 2026 gives way to 2027, and as the five internal task forces Warsh has commissioned report their findings into a policy framework that, as of August 28, 2026, remains explicitly and deliberately unfinished.
