US Blockade and Hormuz Closure: Core Event
President Donald Trump instructed aides to prepare for an extended naval blockade of Iranian ports while Iran kept the Strait of Hormuz closed. The dual blockade has driven Brent crude above $117 a barrel and West Texas Intermediate near $105, marking the highest levels since the conflict began in late February.
Background & Context
The war started on 28 February with coordinated U.S.–Israeli strikes on Iran. Tehran responded by sealing the Hormuz Strait, which carries roughly 20 % of global oil and gas shipments. The United States imposed a “semi-porous” blockade of Iranian ports on 13 April. A cease-fire was declared on 7 April, but diplomatic talks have remained deadlocked.
