OPEC+ raised production by 220,000 barrels per day in response to the supply disruption caused by the conflict. The increase is a rounding error against the scale of the problem. Approximately 20% of the world's traded oil — roughly 17–18 million barrels per day — transits the Strait of Hormuz. The IRGC broadcast on VHF Channel 16 that "no ships may pass" , and vessel traffic through the strait has fallen 70% . The additional barrels cannot reach buyers if the waterway they must pass through is closed.
Brent Crude opened at $82.37 following the initial strikes (ID:108) and has since traded in the $77–80 range — a contained response that prices a short-duration disruption. Goldman Sachs has forecast a peak of $110 per barrel; JP Morgan projects $120–130 if the conflict is prolonged and has raised its US recession probability estimate to 35% (ID:111). The gap between current prices and those forecasts measures the market's bet that the strait reopens within days. If it does not, the repricing will be abrupt.
The US Strategic Petroleum Reserve holds approximately 415 million barrels. At current US consumption of roughly 20 million barrels per day, the SPR covers approximately three weeks if no other source were available. It is designed to smooth temporary disruptions, not to substitute for a prolonged closure of the world's most important oil chokepoint. The six major container shipping lines — CMA CGM, Hapag-Lloyd, Maersk, Nippon Yusen, Mitsui, and Kawasaki Kisen — have already halted all Gulf transits (ID:123). Until they resume, OPEC+ production quotas are an abstraction.
