Trump Threatens U.S. Seizure of Iran's Kharg Island and Oil Infrastructure

Impact verdict

Medium impact. Loss pathway: Kharg Island concentrates ~90% of Iranian crude oil exports. Any actual US military action would imply war risk premium movement across the Persian/Arabian Gulf, mass evacuation of insured energy personnel, potential physical damage to a globally critical asset, and political risk/expropriation exposure for foreign oil company interests. Knock-on retaliatory strikes against Gulf shipping or Saudi/UAE infrastructure could broaden the loss footprint into marine hull, marine cargo and energy onshore books. The President's subsequent reversal of the threat partially offsets the signal but creates volatility around the underwriter assumption set. Severity remains at MEDIUM under the deterministic London Market impact gate: a plausible loss pathway exists but no confirmed insured loss, no port/waterway/airspace closure, no vessel total loss and no market pricing/capacity action has been reported.
