## Prediction

Over the next 24 hours, confirmation of multiple Iranian tankers turning back and CENTCOM’s report of 118 vessels redirected will help drive Brent and Dubai crude prices up by roughly 5–10% as traders reassess the severity and duration of the de facto blockade. Physical buyers in Asia, particularly China and India, will scramble for alternative cargos from Iraq, Saudi Arabia, and Russia, temporarily inflating regional differentials and freight rates. This will increase political pressure on Washington over gasoline prices and on OPEC+ members to adjust quotas. A sharp rise in flat prices and Persian Gulf freight plus widening Iran-related discounts would confirm this; a coordinated US–Gulf statement signaling imminent easing of enforcement would temper the move.

## Drivers

- CENTCOM confirmation of 118 commercial vessels redirected and 5 disabled
- Reports of four NITC crude tankers (~7 mbbl) forced back to port
- Emerging trend of Hormuz crisis driving fragmented, insecure energy system
