## Prediction

Within 30 days, the pattern of drone shootdowns, tanker incidents, and naval close encounters in and around the Strait of Hormuz is likely to harden into a semi-routinized gray-zone confrontation between Iran and the US and its partners. Both sides will continue to test each other with ISR overflights, electronic harassment, and selective boardings or seizures of vessels tied to sanction targets, seeking leverage without crossing into declared war. Commercial operators will be forced to adapt with convoying, routing adjustments, and heavy reliance on naval escorts, institutionalizing higher cost structures. Confirmation would be a steady cadence of non-fatal incidents, advisories, and limited tit-for-tat actions over the month; denial would be a formal deconfliction agreement or a sudden, large-scale clash that breaks the gray-zone pattern.

## Drivers

- IRGC downing of US MQ-1 over Hormuz
- Multiple tanker strikes and escalating warnings on Hormuz risk
- Emerging trend of 'Iran–U.S.–Israel contest hardens around Strait of Hormuz drone warfare'
- Historical 2019–2020 pattern of sustained but managed Gulf incidents
