Trump's 'guardian' fee: How much would supertanker have to pay to cross Hormuz

Adding to transit cost uncertainty, US President Donald Trump has proposed imposing a 20% reimbursement or toll on cargoes that are transported through the Strait of Hormuz. Traditionally, vessels have enjoyed free passage through the Strait of Hormuz under international maritime law, which generally prohibits coastal states from charging ships simply for exercising their right of transit. Unlike man-made canals such as the Suez and Panama, which are sovereign infrastructure and levy substantial transit tolls, most natural international waterways - including the Strait of Hormuz, Strait of Malacca, Taiwan Strait, Strait of Gibraltar and Cape of Good Hope—generally do not charge transit fees, although some collect payments for specific services such as pilotage, tug assistance or navigational support.Also Read | Lights out: How Iran quietly moved millions of barrels through Hormuz under America's nose However, during the recent US-Iran conflict, Iran imposed ad hoc charges on some vessels.
