## Prediction

Over the next 7 days, Iran is likely to implement a de facto partial blockade of the Strait of Hormuz via stepped‑up boardings, drone overflights, close‑approach fast boats, and intermittent missile/drone tests, while stopping short of mining or physically blocking the strait. Traffic of US‑allied and Israeli‑linked vessels will face higher harassment and delays than neutral or Asian‑flagged ships. This strategy allows Tehran to demonstrate capability and resolve, spike energy prices, and pressure Washington and Israel without triggering an immediate multinational kinetic response. Confirmation would be multiple documented harassment incidents and delays plus Iranian media framing them as “control of transit”; denial would be either a near‑normal traffic pattern or an outright mining/closure attempt.

## Drivers

- Iran’s explicit threat to completely close Hormuz and Bab el‑Mandeb
- Emerging trend: US–Iran confrontation as managed multi‑domain coercion around Hormuz
- Recent shootdown of US drone and missile exchanges
- Pattern of past IRGC harassment of tankers under elevated tensions
