President Donald Trump proposed reinstating a blockade of the Strait of Hormuz and imposing a 20% toll [1] on all ships transiting the waterway.

The move targets Iran following attacks on shipping and aims to generate revenue. However, analysts warn the strategy could destabilize global energy markets and fail to secure the cooperation of international allies.

The Strait of Hormuz, located between the Persian Gulf and the Gulf of Oman, serves as a critical chokepoint for global oil exports. By implementing a transit fee, the administration intends to exert economic pressure on the Iranian government. This plan follows regional conflicts that began in mid-2026 [1].

Market reactions to the proposal were immediate. A veteran oil trader said crude prices were hovering just above $100 a barrel [2] as the market reacted to the proposed toll.

Critics argue that the blockade may not achieve its primary goal of forcing a diplomatic breakthrough. A fellow at Israel's Institute for National Security Studies said, "There is little reason to believe that a blockade would force Iranian capitulation" [3].

Opponents of the plan suggest that the move lacks the necessary support from allies to be effective. Without a coalition, the U.S. may find itself managing a volatile maritime environment alone—potentially driving oil prices higher for domestic consumers.

The proposal comes as the administration seeks more leverage in dealing with Iran. Some analysts suggest that the move is an attempt to disrupt Iranian shipping and revenue streams, though they caution that the risk of a wider conflict remains high [3].

"There is little reason to believe that a blockade would force Iranian capitulation."

The proposed toll and blockade represent a shift toward aggressive economic warfare in one of the world's most sensitive maritime corridors. Because the Strait of Hormuz is vital for global energy security, any disruption or added cost to shipping typically results in immediate price increases for crude oil. This creates a tension between the administration's goal of pressuring Iran and the economic necessity of maintaining stable energy costs globally.
