Iran-Linked Maritime Campaign to Normalize as Persistent Low-Intensity Threat to Gulf Shipping
Theater: Strait of Hormuz
Time horizon: 30d

Moderate confidence (71%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Across the next month, Iran and its regional proxies are likely to maintain a pattern of sporadic but strategically timed threats, boardings, or strikes against vessels linked to adversarial states in and around the Strait of Hormuz and the Red Sea. This will entrench a chronic low-intensity threat environment that keeps shipping costs high and compels long-term naval deployments by the U.S., UK, and key regional allies. While full closure of Hormuz remains unlikely, the persistent risk will function as an economic pressure valve in Tehran’s confrontation with Washington. Confirmation would be at least several additional incidents or attempted attacks plus continued elevated naval presence and advisories.
