The U.S. blockade on Iran has reshaped maritime dynamics in the Strait of Hormuz, ending a roughly six-week period during which Iranian oil tankers operated with relative freedom.

The strait is a critical lifeline for Iran’s economy, with around 1.9 million barrels of crude oil passing through it daily, while annual trade flowing عبره exceeds $100 billion.

Iran relies on Gulf ports for more than 90% of its external trade, generating estimated annual revenues of about $110 billion.

Estimates suggest the blockade could inflict direct losses exceeding $400 million per day, due to disruptions at key ports including Bandar Abbas, Imam Khomeini, Kharg, and Asaluyeh.

Bandar Abbas, Iran’s largest port, alone accounts for roughly 55% of the country’s maritime trade, making it one of the hardest hit by the blockade’s impact.
