The 2026 US-Israel-Iran war, which began with strikes on February 28 targeting Iranian leadership and facilities, led Iran to disrupt shipping through the Strait of Hormuz—a critical chokepoint for ~20% of global oil flows—causing sharp oil price volatility (rises of 6-7% on closure fears, drops of 9-12% on temporary reopenings). A fragile two-week ceasefire (initiated early April) is nearing expiration amid ongoing US naval blockade of Iranian ports, recent US seizure of an Iranian-flagged vessel, and Iranian threats to re-close the strait, with stop-start shipping and uncertainty over full oil flow restoration. This has driven surges in energy/fertilizer prices, US gas price impacts, and global food security concerns.
Actors: United States, Iran, Israel · Regions: Middle East, Strait of Hormuz, Persian Gulf · Sectors: Energy, Oil and Gas, Shipping, Fertilizers, Agriculture · Policy instruments: naval blockade, strait closure/threats, airstrikes, ship seizures

Scenarios
| Name | Probability | Description | Key Trigger | Timeline Weeks |
|---|---|---|---|---|
| Ceasefire Collapse and Full Strait Closure | 0.35 | The fragile ceasefire expires without extension as Iran responds to the US naval blockade and vessel seizure by fully mining or blockading the Strait of Hormuz. US and Israeli forces conduct limited strikes on Iranian naval assets and missile sites in the Gulf, while Iran launches asymmetric attacks on shipping and Gulf oil infrastructure. Oil flows drop by over 15% for several weeks, triggering emergency releases from strategic reserves by the US, Europe, and Asia. | Iranian announcement or observable mining/attacks closing the Strait of Hormuz combined with rejection of ceasefire extension. | 2 |
| Negotiated Extension and Partial Reopening | 0.30 | Behind-the-scenes diplomacy involving Qatar, Oman, and backchannel US-Iran talks leads to a 4-6 week ceasefire extension. Iran agrees to limited de-mining and safe passage guarantees in exchange for eased US sanctions on select oil exports and reduced naval presence. Shipping resumes at 70-80% capacity with international monitoring, while Israel maintains pressure but avoids new major strikes. | Public statements from US or Iranian officials signaling willingness for ceasefire extension, accompanied by visible reduction in naval tensions or increased diplomatic shuttling. | 3 |
| Muddling Through with Intermittent Disruptions | 0.20 | The ceasefire is neither fully renewed nor dramatically broken; instead, both sides engage in tit-for-tat actions (limited Iranian harassment of shipping, continued US inspections/blockade elements). The Strait experiences stop-start flows with periodic short closures lasting days. Neither side escalates to major kinetic operations due to mutual economic pain and third-party mediation efforts. | Continued pattern of short-term shipping interruptions without full closure or major military incidents, alongside vague diplomatic statements maintaining ambiguity. | 6 |
| Rapid De-escalation via Multilateral Deal | 0.10 | Unexpected breakthrough occurs through Chinese or European-mediated talks, where Iran commits to keeping the Strait open in exchange for phased sanctions relief and security guarantees regarding Israeli strikes. The US eases its blockade significantly, and a more formal monitoring mechanism (possibly involving neutral parties) is established. Oil flows return close to pre-crisis levels quickly. | Announcement of a new multilateral agreement or verifiable large-scale reopening of the Strait with reduced military posturing from all sides. | 5 |
| Controlled US-Led Escalation to Regime Pressure | 0.05 | The US, backed by Israel, intensifies targeted operations against Iranian Revolutionary Guard naval and missile capabilities while avoiding full invasion. Iran retaliates asymmetrically but suffers significant degradation of its Hormuz disruption ability. The conflict shifts from strait closure to broader pressure on the Iranian regime, with Gulf Arab states quietly supporting the US position. | Observable increase in US/Israeli strikes on Iranian military targets in the Gulf region coupled with statements framing the goal as long-term regime containment rather than immediate ceasefire. | 8 |
