Multilateral Bayesian Scenarios: A Geopolitical Strategic Analysis
Abstract
The joint United States–Israeli military operation codenamed Operation Epic Fury / Roaring Lion, launched on 28 February 2026, and Iran's subsequent retaliatory strikes on Gulf energy infrastructure on 2 March 2026 have precipitated the most severe geopolitical energy shock since the 1990 Gulf War. Within a single trading session on 2 March, Brent crude surged intraday to $82.37 per barrel—its highest level since January 2025—before settling approximately 8.6 percent higher at $79.14. European wholesale natural gas prices simultaneously rose as much as 54 percent after QatarEnergy, the world's largest LNG producer, announced a full halt to liquefied natural gas production following Iranian drone strikes on its Ras Laffan and Mesaieed facilities. This paper applies a Bayesian multilateral game-theoretic framework to assess the systemic consequences of what we term the 'Double-Choke' event—the simultaneous disruption of Saudi Arabia's Ras Tanura refinery and Qatar's Ras Laffan LNG complex—and identifies three plausible strategic trajectories to 2030, ranging from a contained US-led resolution to a structurally bifurcated global energy order or, in the tail scenario, systemic global contagion.
I. The Precipitating Event: Operation Epic Fury and Iranian Retaliation
I.i. The US–Israeli Strike Campaign (28 February – 2 March 2026)
On the morning of 28 February 2026, Israel and the United States launched a coordinated joint military campaign against Iran—codenamed Operation Roaring Lion by the Israel Defense Forces and Operation Epic Fury by the US Department of War. The strikes targeted Iran's senior leadership, nuclear programme, ballistic missile infrastructure, and key military facilities across Tehran, Isfahan, Qom, Karaj, and Kermanshah. Supreme Leader Ayatollah Ali Khamenei, 86, was killed by an Israeli strike at his compound; simultaneously, the IRGC commander, Iran's Defence Minister, and the Secretary of the Supreme National Security Council, Ali Larijani were among the senior figures killed. Iran's state media confirmed Khamenei's death on 1 March and declared 40 days of national mourning. President Masoud Pezeshkian vowed revenge.
The scale and coordination of the operation reflected a qualitative escalation beyond the 12-day Israel–Iran war of June 2025, in which both parties had engaged in more limited symbolic exchanges. The stated objectives of Epic Fury—regime change alongside nuclear disarmament—signal a deliberate departure from earlier containment logic and introduce a prolonged period of structural uncertainty that markets have only partially priced in.
I.ii. Iranian Retaliatory Strikes: The Double-Choke (1–2 March 2026)
Iran's response to the killing of Khamenei was both rapid and strategically calibrated. Beginning on 1 March, the Islamic Revolutionary Guard Corps launched dozens of drones and ballistic missiles across the Persian Gulf, targeting US military bases in Jordan, Kuwait, Bahrain, Qatar, Iraq, Saudi Arabia, and the UAE, as well as civilian aviation infrastructure including airports in Kuwait and Dubai. Six US service members were confirmed killed by 2 March; the Iranian death toll from US–Israeli strikes reached at least 555 civilians and combatants as of the same date.
The targeting of Gulf energy infrastructure on 2 March represented the most consequential phase of the Iranian retaliation. Two distinct nodes—previously treated as informal 'red lines' by regional powers—were simultaneously struck for the first time in the conflict's history:
Ras Tanura, Saudi Arabia
Saudi Aramco's Ras Tanura complex, home to one of the world's largest oil refineries with a throughput capacity of 550,000 barrels per day (b/d), was targeted by Iranian drones on the morning of 2 March. Saudi Arabia's defence forces intercepted two drones; however, debris from the interceptions triggered a fire at the facility. Aramco halted all operations as a precautionary measure. Gasoil futures spiked on the closure. Torbjorn Soltvedt, principal Middle East analyst at Verisk Maplecroft, assessed that the attack—the first Iranian strike on the Gulf's energy infrastructure to result in reported disruption—'has Gulf energy infrastructure now squarely in Iran's sights' and is 'likely to move Saudi Arabia and neighbouring Gulf states closer to joining US and Israeli military operations against Iran.' The halt at Ras Tanura follows a disruption the previous week at the nearby Juaymah liquefied petroleum gas terminal, one of the world's largest exporters of natural gas liquids, compounding supply anxieties.
Ras Laffan Industrial City and Mesaieed, Qatar
Qatar's Defence Ministry confirmed that two Iranian drones struck Qatari energy facilities on 2 March: one targeting a water tank at a power plant in Mesaieed and the other hitting an energy facility within Ras Laffan Industrial City belonging to QatarEnergy. There were no human casualties. QatarEnergy, the world's largest LNG producer accounting for approximately 20 percent of global LNG supply, subsequently issued a formal statement announcing the cessation of all LNG and associated products production. The company operates 14 LNG trains with a combined annual production capacity of 77 million tonnes. Almost all of this output is exported through the Strait of Hormuz. European benchmark Dutch TTF gas prices rose 52–54 percent within hours of the announcement; Asian LNG spot prices jumped approximately 39 percent. Qatar's Foreign Ministry spokesperson stated that the country was 'not engaging with Iran at the moment' and that such attacks 'could not remain unanswered.'
II. Real-Time Market Impact: 2 March 2026
The Islamic Revolutionary Guard Corps (IRGC) has formally declared the Strait of Hormuz closed and threatened to ignite any vessel attempting transit. In strictly physical terms, the Strait has not been hermetically sealed; vessel-tracking data as of 2 March indicate limited traffic continues to move through the corridor. Yet this distinction is analytically secondary. The combination of electronic interference, confirmed attacks on at least four tankers — including one fatality — and the rapid withdrawal of major commercial operators and insurers has produced what is best described as a de facto closure through uninsurability.
Maritime war-risk premiums have surged to six-year highs, rendering transit economically prohibitive for operators lacking explicit sovereign guarantees. In practical effect, market mechanisms — rather than naval blockades — have suppressed throughput. Kpler’s geopolitical analysis team characterised the development as “a real supply disruption, not a risk premium event — physical barrels are being affected across crude, products, LPG, and LNG simultaneously.” This distinction is critical. The episode has moved beyond speculative pricing behaviour into measurable physical constraint across multiple hydrocarbon categories.
On 1 March, International Energy Agency (IEA) Executive Director Fatih Birol confirmed that the agency was “in touch with major producers in the Middle East,” signalling potential coordination of strategic petroleum reserve releases. Simultaneously, OPEC+ announced a production increase of 206,000 barrels per day for April. In structural terms, however, this increment is marginal relative to the scale of disrupted flows.
More importantly, a substantial portion of nominal Gulf spare capacity remains geographically constrained. Even if upstream production increases are technically feasible, export pathways are not. Saudi Arabia’s East-West Pipeline (capacity approximately 7 million b/d) and the UAE’s Fujairah export route provide partial circumvention of Hormuz, yet terminal infrastructure at Jeddah and related Red Sea facilities limits effective sustained throughput well below volumes normally transiting the Strait. Thus, spare capacity is not synonymous with deliverable capacity. The bottleneck is logistical rather than geological.
II.I. Real-Time Market Impact: 2 March 2026
Market reactions on 2 March confirm that investors and traders interpret the situation as a material supply shock rather than a transient geopolitical headline.
Brent crude, which closed the preceding Friday at $72.87 per barrel, surged intraday to $82.37 before settling in the $79.14–79.45 range — an increase of approximately 8.6–9 percent relative to pre-crisis levels. West Texas Intermediate (WTI), which had been trading near $67, climbed to an intraday high of $75.33 before closing between $72.07 and $72.74, reflecting gains of roughly 7.5–8.4 percent.
The natural gas response was dramatically more pronounced. Europe’s TTF benchmark surged by approximately 52–54 percent relative to baseline levels, while Asian LNG spot prices rose roughly 39 percent. US gasoline futures reached $2.496 per gallon intraday, representing gains in the 4.9–9.1 percent range.
This divergence between oil and gas pricing is analytically revealing. The roughly 8–9 percent oil price response contrasts sharply with the 52–54 percent spike in European gas. The explanation lies in structural dependency. European and Asian gas markets have become heavily reliant on Qatari LNG flows — a reliance that deepened deliberately after European consumers reduced exposure to Russian pipeline gas following the 2022 invasion of Ukraine. The strategic substitution of dependency has therefore generated a new chokepoint vulnerability concentrated at Hormuz.
The intraday overshoot in Brent to $82.37, followed by retracement toward ~$79, reflects a classic “fear spike” dynamic. Initial panic pricing was partially tempered as markets absorbed OPEC+’s announced production increase and began assessing whether pipeline alternatives and reserve releases could mitigate the disruption. Yet forward guidance from major financial institutions underscores the fragility of that stabilisation.
Analysts at Barclays warned that a prolonged disruption could push Brent above $100 per barrel. UBS indicated that in a systemic crisis scenario, Brent spot prices could exceed $120. Citi placed its near-term trading range in the $80–90 corridor. Jamie Dimon, CEO of JPMorgan Chase, described the shock as manageable if short-lived but qualitatively “different” if protracted. JPMorgan’s commodities desk separately estimated that a three- to four-week squeeze on Strait traffic could compel Gulf producers to curtail upstream output, thereby driving Brent decisively above $100.
In sum, markets are pricing not merely disruption risk but duration risk. Oil reflects a constrained but partially reroutable system. Gas reflects a concentrated dependency with fewer short-term substitution pathways. The present configuration thus exposes a structural asymmetry: diversification away from Russian pipeline gas reduced one strategic vulnerability while intensifying another at the Hormuz chokepoint.
III. Geopolitical Consequences by Key Actor
III.i. The United States: Strategic Overstretch and Domestic Political Fragility
Operation Epic Fury has exposed the United States to a classic 'costs of success' dilemma. The killing of Khamenei and the decapitation of the IRGC high command achieve declared US–Israeli strategic objectives, but they do not resolve the core energy security challenge they have created. President Trump, speaking at the White House on 2 March, signalled that US strikes on Iran would continue and that the conflict was expected to last 'weeks but could become a prolonged battle.' This guidance directly sustained elevated oil prices through the trading session.
Domestically, each $1 increase in crude oil translates to approximately a 2.5 cent rise in retail gasoline prices. The sustained price surge risks breaching the psychologically significant $4.50/gallon threshold that historical polling associates with sharp declines in presidential approval. With midterm elections in November 2026, a prolonged energy shock functions as a regressive 'tax hike' on the American voter. Congressional dynamics may force a shift towards more isolationist foreign policy framing, even as the military campaign continues. Additionally, the deployment of carrier strike groups and naval assets to the Gulf creates a genuine capacity question regarding simultaneous deterrence commitments in the Indo-Pacific.
III.ii. Europe: The LNG Existential Crisis
Europe's energy security architecture, painstakingly reconstructed after the 2022 Russian gas crisis, has been exposed as critically fragile. The continent's pivot to Qatari LNG—with Qatar accounting for a significant share of EU imports—now represents a single-node dependency of the same structural type as the Nordstream pipeline reliance it was designed to replace. With gas storage at approximately 30 percent of capacity following winter drawdowns, and the Ras Laffan facility offline with no declared timeline for resumption, the risk of energy rationing in Germany and Italy by late 2026 is material. A 52–54 percent intraday TTF spike directly threatens the viability of energy-intensive manufacturing. The social cohesion risks are considerable: high energy prices have historically been the most reliable predictor of European populist electoral momentum.
III.iii. China, Japan, and India: The Asian Vulnerability
China imports approximately 80 percent of its oil through the Strait of Hormuz; Japan and South Korea together account for a large share of global LNG imports from the same corridor. Kpler data indicate that roughly three-quarters of Strait-transiting exports flow to China, India, Japan, and South Korea. China retains an estimated 90 days of strategic petroleum reserves, insufficient to sustain its manufacturing sector indefinitely. Beijing's strategic choice—between mediating a de-escalation that could constrain its Iranian relationships or providing indirect support to Iran to restore transit—will be determinative for the medium-term scenario pathway. India faces acute near-term fiscal exposure: a sustained oil price above $90/bbl for one quarter is projected to widen India's fiscal deficit by approximately 1.2 percent of GDP. Both India and China are assessing immediate pivots toward Russian crude as an alternative supply source.
The Asian LNG shock (+39% in spot prices) is qualitatively distinct from previous disruption episodes in that it represents a simultaneous loss of production (Ras Laffan shutdown) and transit (Hormuz de facto closure), rather than one or the other. This compound disruption severely limits the short-term effectiveness of existing LNG re-routing arrangements.
III.iv. Russia: Structural Beneficiary
Russia is the sole major power whose strategic position has been unambiguously improved by the March 2 events. Elevated energy prices generate direct fiscal revenue from Urals crude sales, which are now trading at a substantial premium relative to recent months. The diversion of Western strategic attention and military assets toward the Gulf reduces the credibility and bandwidth of NATO's support commitments to Ukraine. As of 2 March, Russia had already conducted 217 strikes against Ukrainian grid infrastructure this year; the strategic distraction in the Gulf may accelerate Moscow's timeline for offensive operations. For Chinese and Indian buyers who seek to reduce Hormuz-corridor exposure, Russian crude becomes the natural alternative—a dynamic that further insulates Moscow from Western sanctions.
IV. Bayesian Scenario Analysis: Strategic Trajectories to 2030
This scenario framework conceptualises the present US–Iran–China strategic interplay as a Bayesian incomplete-information game, whereby each principal actor forms probabilistic beliefs about the resolve, capability, and likely responses of the others. The likelihoods assigned below are calibrated as of 2 March 2026 and incorporate observed market and geopolitical signals — notably heightened crude price volatility, elevated insurance costs on tanker transits through the Strait of Hormuz, and persistent military tension following the death of Iran’s Supreme Leader — but remain subject to rapid revision as battlefield and diplomatic developments unfold. Current commodity markets have already reflected such risk premia: Brent crude has been trading above US $80/barrel with brief volatility spikes, and traders are increasingly pricing the risk of extended supply disruption through the key chokepoint at Hormuz. Such dynamics feed through to broader inflation expectations and macroeconomic indicators globally.
Scenario A: The Iron Squeeze — Probability: 45 %
Under this scenario, the United States achieves a decisive degradation of Iran’s Islamic Revolutionary Guard Corps (IRGC) maritime capability within a 30–45 day window. A combination of targeted naval operations and sustained air/naval pressure forces Iran’s residual leadership — now struggling with internal legitimacy challenges following the succession contest post-Khamenei — to accept a de facto ceasefire. Strategic communication channels engage Omani and Swiss intermediaries to manage indirect negotiations, thereby diffusing some face-saving aspects for Tehran while preventing further escalation.
Commercial energy flows through the Strait of Hormuz resume by the second quarter of 2026 under heavy US naval escort and elevated insurance premia, which reflect persistent insecurity despite restored passage. Secondary pipeline routes — notably Saudi Arabia’s East–West Pipeline and the UAE’s Fujairah crude export infrastructure — absorb incremental flows during the transition, mitigating but not eliminating shortages. Global markets, having priced in significant risk premia, experience elevated inflation through 2026 in energy and transport prices, with gradual normalisation as spare capacity rebalances markets.
Within this outcome, the US retains primacy as the Gulf’s security guarantor, albeit at a marked fiscal and reputational cost. The episode accelerates structural diversification efforts across major consuming regions — particularly in Europe and Asia — but does not instantly dismantle the US dollar’s central role in energy pricing; rather, that role is preserved even as participants incrementally hedge away from sole dollar denomination in longer-term contracts. European gas prices, notably at key benchmarks, are structurally elevated relative to pre-crisis levels even after initial shock absorption, reflecting both risk premia and supply chain adjustments.
Scenario B: The Great Divergence — Probability: 35 %
A prolonged contestation of the Strait of Hormuz beyond 60 days anchors this scenario. Iranian succession dynamics produce a hardline interim governing council that refuses de-escalation absent substantive concessions from Washington. US efforts to impose a military or diplomatic settlement stall, and China capitalises on strategic openings by negotiating a “Safe Passage” corridor with the interim Iranian authorities. This corridor is denominated in yuan and supported by selective Chinese naval signalling and escort operations, which reflect Beijing’s broader regional security interests and its sensitivity to domestic manufacturing pressures tied to energy imports.
Global energy markets bifurcate structurally in response. OPEC+ spare capacity rerouted through non-Hormuz channels — including pipelines bypassing the chokepoint and incremental Norwegian and Gulf of Mexico output — remains insufficient to fully offset lost flows, leading to persistent supply deficits, especially for refined products and intermediate fuels. The result is a durably weakened role for the US dollar as the sole pricing currency for energy trade, as alternative pricing arrangements denominated in non-dollar units gain traction within Eurasian supply networks..
The WTI–Brent spread widens permanently, driven by differing regional access constraints and risk premia, while Europe faces a multi-year trajectory of elevated gas prices and an acceleration of forced deindustrialisation in energy-intensive sectors. A new Eurasian energy architecture anchored by Chinese demand and Russian/Central Asian supplies operates in parallel to the Atlantic order, incomplete but highly resilient to disruptions anchored at Hormuz. In this environment, geopolitical alignments shift, with energy security strategies increasingly region specific and decoupled from a unified global pricing regime.
Scenario C: Global Contagion — Probability: 20 %
In this most adverse trajectory, economic desperation and sustained energy scarcity trigger cascading domestic political crises across Europe and South/Southeast Asia. Countries heavily dependent on oil and liquefied natural gas (LNG) shipments via Hormuz — which account for roughly one-fifth of global LPG and LNG trade — confront acute shortages as insurance premia and trading constraints reduce effective flows even absent formal blockade measures. The resulting energy price spikes feed directly into consumer price indices and industrial cost structures, triggering both inflation and output contractions.
Iran’s post-Khamenei disarray is compounded by proxy conflict proliferation, including renewed escalation by allied militias such as Hezbollah, further fracturing regional governance. China, interpreting the simultaneous degradation of US naval bandwidth and European political cohesion as a closing window of opportunity, initiates assertive manoeuvres in the Taiwan Strait, thereby opening a multi-theatre conflict involving major powers.
The global economic order, as practised since 1990, collapses under the weight of these compounded shocks. Integrated supply chains unravel, displaced in favour of regional autarky in energy and manufacturing as nations prioritise secure domestic provision over global trade efficiency. The resulting geopolitical equilibrium is one of structured multipolar confrontation, with discrete blocs defined by security assurances and energy access rather than unified through a US-led order.
Note: These scenario probabilities sum to 100 % and reflect the authors’ Bayesian priors as of 2 March 2026, incorporating the latest market signals, conflict dynamics, and strategic calculations observed in energy markets and geopolitical behaviour. They remain subject to rapid revision in response to shifts in battlefield realities, diplomatic breakthroughs, or sudden energy market realignments.
V. Critical Risk Assessments
V.i. The Uninsurability Problem
The most underappreciated near-term risk is not the physical closure of the Strait but its functional closure through the collapse of maritime insurance. Insurance premiums have reached six-year highs; private war risk underwriters have already begun declining Gulf-corridor coverage. Without state-backed guarantees from G7 governments, commercial tanker operators cannot secure coverage and will not transit regardless of military presence. This dynamic—market failure rather than military failure—can persist long after kinetic security conditions have nominally improved, and it affects the effectiveness of Saudi and UAE pipeline route alternatives in capturing diverted flows.
V.ii. Iranian Succession Uncertainty
The killing of Khamenei introduces a profound and analytically novel uncertainty. Unlike prior Middle Eastern regimes that collapsed upon leadership removal, Iran's governance structure is institutionalised and decentralised. The Islamic Revolutionary Guard Corps retains organisational coherence, though its top command has been decimated. The succession process—formally governed by the Assembly of Experts—may produce a more pragmatic figure, a hardliner consolidating around military institutions, or a prolonged factional paralysis. Each outcome implies a materially different de-escalation pathway. Markets and policymakers should not assume that regime change translates automatically into energy market stabilisation: the interregnum itself is a period of maximum strategic risk.
V.iii. The Taiwan/Ukraine Escalation Nexus
The strategic distraction calculus is real and time-sensitive. Beijing's assessment of US naval bandwidth is being continuously revised as carrier strike group deployments are publicised. The six US service members already killed in Iranian retaliatory strikes indicate that the conflict has moved beyond proxy engagement. Russia's ongoing grid strikes in Ukraine are consistent with a deliberate attempt to capitalise on reduced Western focus. The probability of a Taiwan escalation attempt rises non-linearly if the Gulf conflict extends beyond 60 days and appears to consume a second carrier group. This nexus—Gulf, Taiwan, Ukraine—represents the tail risk that transforms Scenario A into Scenario C.
VI. Recommended Policy Responses
VI.i. G7 War Risk Insurance Facility
The most immediate and highest-leverage intervention available to G7 governments is the establishment of a state-backed war risk insurance pool for Gulf-corridor tanker traffic. Private insurers have effectively exited the market; without public-sector underwriting, pipeline route alternatives and strategic reserve releases cannot fully substitute for Strait transit volumes. A coordinated G7 facility—modelled on the post-9/11 aviation insurance backstop—should be activated within 72 hours of any declared intent to maintain commercial shipping lanes.
VI.ii. Coordinated Strategic Reserve Release
A coordinated IEA-led release of at least 60 million barrels from G7 strategic petroleum reserves would address both the physical supply gap and the psychological price spiral. The IEA director's engagement with Gulf producers on 1 March signals readiness to act; the OPEC+ April production increase of 206,000 b/d provides a fig-leaf of market cooperation. However, visible oil inventories globally stood at approximately 74 days of demand as of the onset of the crisis—near historical median—which means the buffer is adequate only for a short-duration disruption. A release should be announced preemptively, not reactively, to maximise its price-dampening effect.
VI.iii. Diplomatic Backchannel Architecture
The Omani and Swiss foreign ministries have historically served as the most effective backchannel conduits between Washington and Tehran. Their activation should be pursued in parallel with kinetic operations, not sequentially. The precedent of the June 2025 nuclear talks—in which Shamkhani had indicated that 'an immediate agreement [was] within reach'—suggests that elements of Iran's political system retained a transactional orientation even before the 28 February strikes. Post-Khamenei, identifying the relevant interlocutors and establishing their authority to negotiate is the paramount diplomatic task. Any framework should include explicit 'Energy Neutrality' guarantees—a mutual commitment not to target energy infrastructure—as a confidence-building precondition to broader de-escalation.
VI.iv. Energy Sovereignty Measures for G7 Partners
Over the medium term, the crisis validates the strategic logic of treating LNG and crude oil as national security assets rather than spot-market commodities. The US Permian Basin and Norwegian Continental Shelf should be directed, through emergency procurement agreements, to prioritise supplies to G7 partners. The European Commission should activate its emergency gas coordination mechanism and establish intergovernmental offtake agreements with alternative LNG suppliers (Australia, US Gulf Coast) to reduce structural dependence on Qatari volumes. These measures will not resolve the immediate crisis but are essential to preventing Scenario B from becoming self-fulfilling through European political fragmentation.
VII. Conclusion
The events of 28 February–2 March 2026 constitute a threshold rupture in the post-Cold War energy architecture. The simultaneous disablement of Ras Tanura and Ras Laffan—the world's two most critical single-node energy processing facilities—and the functional closure of the Strait of Hormuz through a collapse of commercial insurance represent a qualitatively different order of shock than prior Middle Eastern disruptions. The killing of Supreme Leader Khamenei removes the principal figure around whose decision-making Iranian foreign policy had cohered for 35 years, introducing a succession uncertainty that makes even the negotiated de-escalation scenario (Scenario A) highly contingent. The probability that the global economy has already entered recession territory—conditional on disruptions persisting beyond 21 days—is material. The probability that this energy shock becomes the catalyst for a broader multi-theatre confrontation is no longer trivially small.
Sound policy requires simultaneous action on four tracks: military (ensuring escalation dominance while avoiding widening), diplomatic (engaging residual Iranian interlocutors before hardliners consolidate), market (insurance backstop, reserve release), and structural (emergency G7 energy solidarity agreements). Failure on any one of these tracks will substantially elevate the probability of transitioning from Scenario A to Scenario B or C. The 14-day window referenced in this paper's introduction is not rhetorical: it corresponds to the operational timeline at which insurance market withdrawal, just-in-time supply chain disruptions, and European gas storage dynamics begin to produce irreversible economic damage.
