The Office of Foreign Assets Control has warned global shipping companies that they could face sanctions if they make payments to Iran in exchange for safe passage through the strategically vital Strait of Hormuz, escalating pressure amid ongoing geopolitical tensions.
In an advisory, the US agency said both American and non-American entities risk punitive action if they engage in financial transactions with Iran linked to maritime transit. The warning specifically targets what officials described as a “tollbooth” system, under which vessels were reportedly charged fees to navigate alternative routes near Iran’s coastline.
The development follows months of disruption in the strait, after Iran curtailed regular shipping traffic during heightened conflict involving the United States and Israel earlier this year. While limited vessel movement has since resumed, access has remained restricted and conditional.
In response to Iran’s actions, the United States imposed a naval blockade on April 13, preventing Iranian oil tankers from exiting the region. The United States Central Command said that at least 45 commercial vessels have been instructed to turn back since the blockade took effect.
The Strait of Hormuz, a critical artery for global energy supplies, handles a significant share of the world’s seaborne oil trade. Any disruption or escalation in the region is closely watched by shipping markets, energy traders, and governments worldwide.
