## Prediction

Within the next 24 hours, Iranian forces are likely to intensify non-lethal harassment of commercial shipping and US/Gulf naval assets around the Strait of Hormuz—using fast boats, drones, and electronic interference—without yet launching mass-casualty strikes. Shipping companies, Gulf states, and US naval forces will face higher operational risk and routing delays, but most tankers already in the Gulf will not be physically disabled. This pattern would harden the perception of a de facto blockade while Iran tests red lines and coalition rules of engagement, feeding a higher risk premium into oil and LNG without triggering immediate full-scale conflict. Confirmation would include AIS spoofing incidents, close passes by IRGCN craft, or drones over transiting tankers; a contrarian outcome would be an unexpected quieting of IRGCN activity due to backchannel pressure from China or Oman.

## Drivers

- Iran’s public declaration that Hormuz is blocked until conditions are met
- Shift to an ‘offensive’ doctrine signaling more coercive behavior
- Ongoing US–Iran multi-domain confrontation and blockade-war trajectory
