U.S. President Donald Trump said the outcome of events in the Strait of Hormuz could cause oil prices to drop "down like a rock".

Control and accessibility of the waterway are critical to global energy security because the strait serves as the primary oil-transit route between Iran and Oman. Any shift in the status of this passage directly impacts the cost of crude oil for consumers worldwide.

Trump said the United States could charge ships for passage through the waterway. He linked the status of the strait to global energy markets, saying a positive outcome would be "extremely good" for oil prices [1].

The volatility of the region has already manifested in sharp market swings. Brent crude oil prices rose past $110 per barrel after Iran announced the Strait of Hormuz was closed [3]. This spike highlighted the fragility of the supply chain when the waterway is obstructed.

Market trends shifted again on Friday when oil prices plunged following a statement from Iran’s foreign minister that the Strait of Hormuz was completely open [2]. The sudden availability of the route led to a significant price drop, though a specific figure for the plunge was not provided [2].

Trump's comments regarding passage fees come as the administration monitors the geopolitical stability of the region. The proposal to monetize the security or administration of the strait represents a shift in how the U.S. might approach the management of international waters in high-tension zones.

The administration continues to weigh the relationship between regional diplomacy, and the stability of energy costs. Trump said that the current trajectory of events in the strait remains a primary driver for the future of global oil pricing [1].

Oil prices could drop "down like a rock".

The Strait of Hormuz is one of the world's most strategic chokepoints; any disruption there creates immediate global inflation through energy costs. By suggesting the U.S. could charge for passage, the administration is signaling a move toward treating maritime security as a paid service or a diplomatic lever, while simultaneously attempting to influence oil prices through geopolitical pressure.
