President Donald Trump issued a stern warning to Iran on Thursday, demanding it stop any efforts to impose tolls on ships passing through the Strait of Hormuz. In a social media post, Trump stated, "There are reports that Iran is charging fees to tankers going through the Hormuz Strait. They better not be and, if they are, they better stop now!"

The admonition comes just two days after a fragile ceasefire took effect between the United States and Iran, following a month-long conflict that began on February 28 when U.S. and Israeli forces struck Iranian targets. Iran retaliated with attacks on Israel and U.S. bases in Gulf states. The ceasefire stipulated the complete, immediate, and safe reopening of the strait, a vital chokepoint for roughly 20% of global oil and liquefied natural gas shipments.

Despite the agreement, ship traffic through the strait remains at less than 10% of normal levels. Hundreds of tankers are backed up, stranding nearly 20,000 mariners in the Persian Gulf, as Iran asserts control by directing vessels to stay in its territorial waters. Reports indicate Iran plans to charge fees, potentially $1 per barrel payable in cryptocurrency, to allow passage.

Iranian officials, including a spokesperson for the Oil, Gas and Petrochemical Products Exporters' Union, Hamid Hosseini, confirmed demands for such payments during the two-week ceasefire period. Supreme Leader Ayatollah Seyyed Mojtaba Hosseini Khamenei stated that management of the strait will enter a "new stage," emphasizing Iran's victory in the war and its intent to protect its rights while seeking compensation.

Trump added that oil would soon flow "with or without the help of Iran," underscoring U.S. resolve. He has previously threatened severe consequences, including strikes on Iranian infrastructure, if the strait remained closed, and even floated U.S. tolls or a joint venture as alternatives.

The standoff has exacerbated global energy disruptions, with oil prices hovering near $100 per barrel, well above pre-war levels. Western leaders have rejected any toll payments, viewing them as a violation of free navigation norms. Defense Secretary Pete Hegseth has signaled U.S. readiness to ensure passage if needed.

As tensions simmer, the focus remains on whether Iran complies or risks escalating the ceasefire's fragility. The Strait handles about 25% of seaborne oil trade, making unrestricted access critical for global markets.
