Houthi Wildcard: Dual Chokepoint Disruption and the $130 Oil Threshold
MiroFish simulation of 20 AI agents assigns 42% probability to Brent crude hitting $130-145 if Houthis activate dual Hormuz-Red Sea chokepoint disruption.
Executive Summary
The Strait of Hormuz is already half-shut. The Red Sea has been a combat zone for over two years. What the market has not fully priced is the Houthi wildcard: a deliberate, coordinated activation of both chokepoints simultaneously, timed to the ongoing US-Israel-Iran conflict.
A 20-agent MiroFish simulation run on March 28, 2026 puts the probability of that scenario at 42% -- with Brent crude settling between $130 and $145 per barrel. The weighted expected oil price across all four scenarios is approximately $122/bbl. Consensus among military-modeled agents: 73% assessed that the US lacks sufficient carrier capacity to fight a coherent two-front maritime war.
That finding deserves more attention than it is getting.

Background and Context
The Strait of Hormuz handles roughly 20% of global oil flow and about 25% of liquefied natural gas traded internationally. The 2026 Hormuz crisis, triggered after US and Israeli strikes killed Iran's supreme leader in early March, has already been described by Wikipedia as "the largest disruption to the energy supply since the 1970s energy crisis."
Simultaneously, Houthi forces in Yemen have maintained asymmetric attacks on Red Sea shipping since November 2023. By March 2026, the Bab al-Mandeb Strait -- the southern chokepoint connecting the Red Sea to the Gulf of Aden -- has seen multiple attacks per week. BP, Shell, and Trafigura suspended Red Sea transits entirely over a year ago. Most traffic still uses the Cape of Good Hope route, adding 10-14 days of transit and substantial cost.
The strategic picture: two of the world's five critical oil chokepoints are simultaneously under threat. Neither is fully closed. Both are partially degraded. And the Houthis, whose leadership has publicly declared they are "monitoring developments and will know when is the suitable time to move," have not yet committed their full asymmetric capacity.
That is the wildcard the simulation was designed to stress-test.
Reuters reported on March 27 that analysts see Brent ranging between $100 and $190 under sustained supply disruption, averaging around $134. Our simulation arrived independently at $122 weighted mean -- slightly more conservative, but the distribution shape is similar.
Methodology
Platform: MiroFish multi-agent simulation infrastructure
Simulation ID: sim_8aa1f8cb728e
Project: proj_aa1d237b9547
Graph: mirofish_134c353e712e4d53
Agents: 20
Rounds completed: 35 of 40 (out-of-memory event at round 19; force-restart succeeded)
Run date: 2026-03-28, 18:00-18:25 MYT
Report: report_a56d0f4f93e9
The simulation assigned agent roles across military strategy, energy markets, geopolitics, and regional diplomacy. Each agent operates independently with access to the same base information set, then negotiates positions through structured debate rounds. Consensus emerges from convergence or documented disagreement. No agent can override another's assessment -- the simulation captures genuine disagreement where it exists.
The core question posed: If Houthi forces actively coordinate with Iran to disrupt both Hormuz and Bab al-Mandeb, what is the probability distribution across escalation outcomes, and what does each imply for oil price over a 30-day horizon?
Agent debate structure. Military agents converged first; economic agents showed the widest disagreement range.
Key Findings
Scenario A: Multi-Front Escalation -- 42% Probability, Brent $130-145
The leading scenario. Houthis activate anti-ship missile and drone campaigns against Bab al-Mandeb at scale, simultaneously with ongoing Hormuz tanker harassment. The US, already managing carrier deployments across the Persian Gulf, cannot adequately suppress both fronts. Saudi Arabia increases Red Sea defensive posture but does not re-enter Yemen militarily.
Oil markets treat dual chokepoint degradation as a structural supply shock rather than a temporary spike. The 51% of agents who assessed Brent hitting $130+ within 30 days were concentrated in this scenario.
Scenario B: Calibrated Stalemate -- 31% Probability, Brent $110-125
Houthis escalate rhetoric but limit kinetic action to below a threshold that would trigger full US military retaliation. They extract political and financial concessions from Iran in exchange for restraint. The market remains risk-elevated but not in shock mode. Brent stays in the $110-125 range as SPR releases and alternative routing absorb partial pressure.
Scenario C: Forced Ceasefire -- 18% Probability, Brent $85-100
Diplomatic intervention -- most likely Gulf-mediated with Qatari involvement -- produces a ceasefire framework within 2-3 weeks. Houthis stand down in exchange for security guarantees and Yemen reconstruction commitments. Hormuz partially reopens. Markets rapidly reprice toward pre-conflict levels. This is the scenario the market is arguably most eager to believe, which the simulation flags as a reason to discount it.
Scenario D: Total Regional War -- 9% Probability, Brent $150+
Houthis launch coordinated attacks on Saudi Aramco infrastructure as well as maritime chokepoints. Iran activates proxy networks in Iraq and Lebanon in parallel. US commits to full maritime suppression campaign, triggering direct Iranian countermeasures. Full Hormuz closure and Red Sea denial together. This is the fat-tail scenario -- low probability but potentially structurally repricing global energy markets for years.
Probability-weighted oil price distribution. The $130+ tail carries more weight than current market pricing implies.
Market Implications
The consensus $122/bbl is not priced in. Brent was at approximately $92 on March 11, 2026 per CNBC. Even at its elevated post-conflict levels, the market is not fully discounting the Houthi activation probability.
Saudi Arabia is the swing variable the simulation identified most confidently. A Saudi re-entry into Yemen -- which agents assessed as approximately 30% likely if Houthis attack Aramco infrastructure -- changes the calculus entirely. It either accelerates Scenario C (ceasefire pressure) or escalates toward Scenario D depending on Iranian response.
Insurance and shipping rates lead physical prices by days. If Houthi activity escalates at Bab al-Mandeb, tanker war-risk premiums will spike before Brent moves. This is the earliest tradeable signal.
US carrier capacity is the binding constraint, not will. The Washington Institute has flagged the carrier gap issue: the US simultaneously managing the Persian Gulf and Red Sea theaters stretches carrier strike group deployment cycles. Our simulation's 73% military-agent consensus on this constraint aligns with public analysis. The Houthis understand this arithmetic.
Second-Order Effects
Cape of Good Hope saturation. If Red Sea routing becomes untenable again at scale, Cape routing absorbs the overflow. But that route is already congested from the 2024-2025 Red Sea crisis. Cape transit costs would spike further, adding inflationary pressure to European energy imports specifically.
LNG markets compound the oil shock. Hormuz handles 25% of global LNG trade. A dual chokepoint scenario hits natural gas simultaneously with oil. European gas prices, which had stabilized somewhat, face renewed pressure at precisely the wrong seasonal moment.
Emerging market currency pressure. Oil-importing emerging markets -- particularly South and Southeast Asia -- face dual pressure from higher import costs and dollar strengthening as commodity stress drives safe-haven flows. The simulation did not model currency markets explicitly, but the energy shock transmission is direct.
OPEC+ cohesion breaks under price pressure. At $130+, OPEC members face divergent incentives. Saudi Arabia wants price stability and regional security. Russia wants maximum revenue. UAE has pipeline alternatives that let it partially route around Hormuz. Coordination fractures.
Risk Assessment
What would invalidate the 42% multi-front escalation finding:
-
Rapid ceasefire in the US-Iran conflict. If the main war de-escalates, Houthi leverage evaporates and their calculus shifts toward negotiation.
-
Houthi internal fracture. Multiple Houthi factions have different relationships with Iran. A split between hardliners wanting full activation and pragmatists could suppress coordinated action.
-
US surge of additional naval assets. Deploying a third carrier strike group to the region would close the capacity gap agents identified. Force projection changes the deterrence equation.
-
Saudi-Houthi back-channel deal. Historical precedent exists. If Saudi Arabia offers credible incentives, Houthi restraint at Bab al-Mandeb becomes rational.
The 9% total-regional-war scenario is the asymmetric risk that most deserves monitoring. Low probability, but if it materializes, the simulation has no historical price anchor to use. $150+ Brent is a floor in that scenario, not a ceiling.

Conclusion
The market is treating the Houthi threat as a contingency. The simulation suggests it is closer to a base case.
A Houthi leader told Reuters they are "monitoring developments and will know when is the suitable time to move." That is not a group signaling restraint. That is a group with an asymmetric weapon, watching for the optimal moment to deploy it.
The dual chokepoint scenario -- both Hormuz and Bab al-Mandeb simultaneously degraded -- is a 42% probability event according to 20 independent AI agents running 35 debate rounds. That is not a tail risk. That is a coin flip with a $130+ oil outcome on one side.
If you want to understand why commodity traders should be watching Saudi Arabia's posture toward Yemen rather than the Hormuz headlines, that is your answer.
