President Donald Trump (R-FL) has retreated from a proposal to impose tolls on vessels transiting the Strait of Hormuz [1, 2].

The proposal threatened to disrupt one of the world's most critical maritime chokepoints, where a significant portion of global oil supplies pass between Oman and Iran [1, 2].

Reports from April 2026 indicated the administration considered a fee of approximately 20 percent of a ship’s cargo value [3]. The plan was intended to generate revenue and increase pressure on Iran [1, 4]. However, the move faced immediate pushback from international allies, including the United Kingdom [4].

Legal experts and diplomats said the proposal was illegal under international maritime law [4]. The financial implications of the toll were substantial; industry analysis suggested the fee could more than double the cost of transporting oil from the Gulf to Europe [3].

Despite the initial planning, the administration backed down from the threat to levy the tolls [4]. The shift follows a period of volatility regarding how the U.S. manages the narrow waterway [2, 4].

The proposed toll would have been 20 percent of a ship’s cargo value.

This episode highlights the tension between the administration's desire to use economic leverage against Iran and the constraints of international maritime law. By attempting to monetize the Strait of Hormuz, the U.S. risked alienating key European allies and triggering a spike in global energy prices, demonstrating the limits of unilateral economic pressure in critical shipping lanes.
