Iran’s Revolutionary Guards claim to have seized a U.S. underwater vehicle in the Strait of Hormuz
Question
Iran’s Revolutionary Guards claim to have seized a U.S. underwater vehicle in the Strait of Hormuz
Direct answer
The disputed claim raises uncertainty around U.S.-Iran maritime surveillance and can increase the risk premium in crude, tanker freight and war-risk insurance without establishing that a U.S. asset was actually lost.

| Asset | Exposure and channel | Direction | Evidence |
