US Threatens Sanctions on Shipping Firms That Pay Iran Tolls

May 2, 2026 — The US government issued a stark warning to international shipping companies on Friday: pay tolls to Iran for passage through the Strait of Hormuz, and face American sanctions. The threat marks a further escalation in US-Iran tensions.

According to BBC reports, the US Secretary of State stated in a declaration that any shipping company paying “tolls” or similar fees to the Iranian regime could be placed on a sanctions list. The Strait of Hormuz is one of the world's most critical oil transit routes, with approximately one-fifth of global oil supplies passing through it.

Meanwhile, President Donald Trump expressed dissatisfaction with Iran's latest peace proposal. CBS News live updates showed Trump saying he was “not excited” by Iran's new offer, suggesting the proposal falls short of Washington's core demands.

Hormuz Strait Tensions Escalate

Iran has been attempting to pressure the international community by imposing “tolls” on vessels transiting the Strait of Hormuz. The move has drawn strong opposition from the US and its allies, who consider it a violation of international law.

A statement from the US Treasury noted that paying such fees to Iran equates to funding Iranian military activities. The White House National Security Council said the US would “take all necessary measures” to protect freedom of international navigation.

Impact on Global Shipping

Shipping industry analysts warn that the US sanctions threat could have ripple effects across global supply chains. Major shipping companies including Maersk, Mediterranean Shipping Company (MSC), and COSCO all rely on the Strait of Hormuz for energy transport.

“This puts shipping companies in a difficult position,” said a maritime lawyer who wished to remain anonymous. “They risk either violating Iranian regulations or facing US sanctions.”

Background on Iran Situation

The Iran war has now reached the 60-day mark, with congressional debate over war authorization intensifying. Trump wrote to Congress stating that, due to a ceasefire agreement, hostilities with Iran have “terminated” and thus do not require congressional authorization. However, this claim has been questioned by lawmakers from both parties.

The New York Times reported that as the Iran war enters its 60th day, Republican frustration with Trump is growing in Congress.
