Donald Trump said Monday that the U.S. is reinstating a blockade of Iran in the Strait of Hormuz [1].

The move targets one of the world's most critical oil transit chokepoints. By asserting control over the waterway, the U.S. seeks to exert economic and military pressure on Tehran during a period of escalating regional tensions [2].

Trump said the U.S. will act as the guardian of the Strait of Hormuz to ensure safe passage [3]. As part of this new maritime strategy, the U.S. will charge commercial ships a 20% fee [4] for safe passage through the narrow waterway between Oman and Iran [5].

This decision follows a series of heavy exchanges of fire between U.S. and Iranian forces [6]. Recent military activity included U.S. airstrikes on Iran after Tehran targeted Gulf states [7]. Both nations have asserted control over the strait as the conflict intensifies [8].

The blockade aims to restrict Iranian activity while providing a security umbrella for commercial traffic. However, the imposition of a fee on global shipping is an unconventional approach to maritime security, one that may impact global energy prices and shipping insurance rates.

U.S. officials have not yet detailed the mechanism for collecting the passage fees or how the funds will be allocated. The announcement comes as the U.S. military maintains a high state of readiness in the Persian Gulf to counter potential Iranian naval provocations [2].

The reinstatement of the blockade and the introduction of a passage fee signal a shift toward an aggressive 'security-for-hire' model in a strategic chokepoint. By monetizing safe passage, the U.S. is not only attempting to isolate Iran financially but is also asserting a level of sovereign control over international waters that could provoke further legal and military challenges from both Iran and global shipping conglomerates.
