Iran has effectively shut down the Strait of Hormuz, a critical maritime chokepoint between Iran and Oman. The blockade has stranded approximately 20,000 seafarers in the Persian Gulf, severely disrupting global oil flows through a strait that handles about 21% of the world's oil transit.
The United States has responded with a counter-blockade, seizing Iranian oil tankers and enforcing strict sanctions. Iran's oil storage is near capacity, adding economic pressure on the country.
Market indicators suggest increasing instability. The probability of a US blockade lift announcement by May 31 has dropped to 40.5%, down from 44% a day earlier and 63% a week ago. Vessel traffic normalization remains unlikely in the near term.
Key developments to monitor include diplomatic engagements involving the US, Iran, and potential mediators like Pakistan, as well as any changes in military posturing by CENTCOM or Iranian forces.
