On 19 July 2019, IRGC Navy fast boats and a helicopter seized the British-flagged tanker Stena Impero as it transited the Strait of Hormuz, forcing it to Bandar Abbas with its twenty-three crew aboard. The seizure was widely read as retaliation: two weeks earlier, on 4 July, Royal Marines had detained the Iranian tanker Grace 1 (later renamed Adrian Darya 1) off Gibraltar on suspicion of carrying oil to Syria in breach of EU sanctions.
The Stena Impero was held for roughly two months, its crew confined aboard, before its release in late September 2019. The episode came amid the unraveling of the 2015 nuclear deal after the US withdrawal in 2018, and a summer of tanker incidents — including limpet-mine attacks near the Gulf of Oman in May and June that Washington attributed to Iran. It showed how quickly the world's most important oil chokepoint can become an instrument of state leverage.
