## Prediction

Within seven days, Iran is likely to intensify harassment of commercial shipping and attempt de facto constraints on traffic through the Strait of Hormuz, short of openly mining the strait. Actions could include boarding attempts, UAV overflights, close IRGCN passes, and selective slowdowns or diversions framed as inspection or security measures. This will force the US and allied navies to commit additional escorts and ISR assets, raising collision and engagement risks and potentially leading East Asian importers to publicly press for de-escalation. Confirmation would be multiple reported boarding or diversion incidents and NOTAMs or NAVTEX warnings; disconfirmation would be sustained normal traffic patterns and verified Iranian orders instructing naval units to avoid foreign-flag vessels.

## Drivers

- Trump describing US naval blockade as completely shutting off Iranian trade
- Iran’s 'steel wall' blockade rhetoric indicating contested maritime control narrative
- US strike on tanker off Oman heightening perceived maritime threat
- Historical Iranian pattern of tanker seizures and harassment during crises
