U.S. Reinstates Iran Sanctions After Shipping Attacks Resume in Strait of Hormuz

President Trump reinstated sanctions on Iranian oil and reimposed the U.S. blockade of Iranian ports after Iranian forces resumed attacks on shipping in the Strait of Hormuz. The nearly five-month conflict has included two earlier ceasefires that failed to restore free passage through the waterway. The memorandum of understanding signed about a month ago was declared void by the United States.

Background on the Agreement The memorandum allowed Iran to make arrangements for safe passage of commercial vessels with no charge for the first 60 days and required Iran to conduct talks with Oman on future administration of the strait. U.S. officials had viewed the document as restoring unobstructed passage, while Iranian officials interpreted it as preserving their control and the option to impose fees after the initial period.

The United States has stated it will control the strait and may seek a 20 percent fee on shipping. Iranian forces have continued limited disruption using threats and projectiles. Domestic political support for continued military involvement remains limited, and officials have not announced further steps.
