US orders Hormuz blockade
The United States has ordered a naval blockade of maritime traffic entering and exiting Iranian ports, a significant escalation of naval operations around the Strait of Hormuz. Markets reacted immediately, with reports saying oil prices pushed above $100 a barrel as traders priced shipping and energy disruption risk into markets. (insidenova.com / indianexpress.com)
President Donald Trump said on April 12 that the United States Navy would begin blockading ships entering or leaving Iranian ports through the Strait of Hormuz after U.S.-Iran talks in Pakistan collapsed. (cnbc.com) U.S. Central Command said the operation starts Monday, April 13, at 10 a.m. Eastern time and applies to vessels of all nations entering or departing Iranian ports, while ships sailing between non-Iranian ports can still transit the strait. (pbs.org) Trump also said the Navy would intercept vessels that paid Iran tolls for safe passage, and he tied the move to failed ceasefire talks in Islamabad over Iran’s nuclear program. (politico.com) The Strait of Hormuz is the narrow sea lane between Iran and Oman that carries about 20 million barrels a day of crude oil and petroleum products, making it one of the world’s busiest energy chokepoints. (iea.org) The U.S. Energy Information Administration said oil flows through the strait averaged about 20% of global petroleum liquids consumption in 2024, and the agency said few alternative routes exist if traffic is disrupted. (eia.gov) Oil traders reacted before the blockade took effect. Brent crude and West Texas Intermediate both jumped above $100 a barrel in early Monday trading as markets priced in supply and shipping risk. (energynow.com) Iran’s Revolutionary Guards said military vessels approaching the strait would be treated as a ceasefire breach, underscoring the risk that a shipping enforcement mission could turn into direct naval confrontation. (energynow.com) The move follows a two-week crisis in which Iran had restricted traffic through Hormuz and Washington had demanded a full reopening while negotiators tried to turn a battlefield pause into a broader settlement. (abcnews.go.com) What happens next depends on enforcement at sea: whether commercial shippers avoid Iranian ports, whether insurers raise rates again, and whether Iran tests the blockade with its own naval or proxy forces.
