Theater: Strait of Hormuz
Time horizon: 7d

Low-moderate confidence (55%)
Risk direction: escalatory · Impact: CRITICAL
Executive summary
Over the coming week, the combination of Trump’s threats to “hit Iran very hard” and IRGC insistence on keeping Hormuz shut makes a limited naval or air skirmish around the strait increasingly likely—such as warning shots, drone shootdowns, or disabling fire against small craft. U.S. naval forces will intensify presence operations to assert freedom of navigation, while Iran probes red lines with fast-attack boats and coastal missiles. Even a short, localized incident would trigger immediate spike in energy prices, calls for convoy protection, and renewed debate over war powers in Washington and allied capitals. Confirmation would be mutual claims of hostile acts at sea; denial would involve both sides quietly…
