## Prediction

In the next 24 hours, Brent and WTI benchmarks are likely to rise by roughly 3–7% as markets fully price in the US-declared total blockade of Iranian ports and confirmed mine presence in Hormuz. Even without an actual closure of the strait, insurance premia, freight rates, and risk hedging activity will drive a higher geopolitical risk premium. Traders will also factor in additional risk from drones near UAE nuclear and power infrastructure. Price gains could be partially capped by expectations of SPR flexibility and non-Iranian OPEC+ spare capacity, but the net move will be upward.

## Drivers

- CENTCOM confirmation of 89 commercial vessels redirected from Iranian ports under a 'total blockade'
- US intelligence detection of at least 10 naval mines in the Strait of Hormuz
- Warnings that Hormuz tensions raise global oil transit risk premium
- New US 'Economic Fury' sanctions tightening enforcement on Iranian crude exports
