## Prediction

Within 7 days, at least one additional harassment or low-level attack on commercial shipping near the Strait of Hormuz—possibly via drone fly-by, limpet mine, or suspicious boarding—is likely, plausibly conducted by Iranian-linked proxies to increase pressure without overt IRGC attribution. The objective will be to raise costs for Western-aligned economies and demonstrate the credibility of Iran’s threat to 'change geography of war' after US drone operations and tanker incidents. This will widen the perceived war-risk zone beyond a single strike and incentivize calls for naval escort regimes. Confirmation would be new UKMTO or insurer advisories reporting a 'suspicious approach' or minor damage event with suspected Iranian nexus; denial would be a full week of incident-free transit and IRGC signaling focused solely on defense.

## Drivers

- Tanker hit by projectile in Hormuz and follow-on tanker strike alert
- IRGC threat to expand geography of war if US strikes again
- Iran’s historical use of plausible-deniability attacks on shipping
- Heightened gray-zone trend in Middle Eastern maritime tensions
