The Strait of Hormuz crisis has moved from a military flashpoint to a direct shipping emergency. The United Nations’ maritime agency says vessels should avoid transiting the waterway until safety conditions return, after renewed U.S.-Iran fighting and reported attacks on merchant ships pushed traffic in one of the world’s most important energy corridors toward another near-standstill.
UN News reported that International Maritime Organization Secretary-General Arsenio Dominguez said all transit through the Strait should be avoided “until the necessary safety conditions are in place.” The IMO also said the evacuation of stranded seafarers would remain on hold for security reasons.
According to the UN report, 136 ships and roughly 2,900 seafarers have been evacuated so far. The warning followed alleged attacks on three merchant ships that were transiting Hormuz despite a June 17 truce framework between Washington and Tehran.
Why Hormuz Is Back at the Center of the Crisis
Hormuz is the narrow passage between the Persian Gulf and the Gulf of Oman, and it carries about one-fifth of global oil and gas supplies. Before the war, the UN said around 130 commercial ships moved through it each day. Any sustained disruption quickly becomes a global energy and insurance problem, not just a regional military one.
The latest flare-up has also put the June memorandum of understanding under heavy strain. That agreement called for a halt to military operations, 60 days of negotiations, a final settlement on Iran’s nuclear program, sanctions relief, and the reopening of Hormuz to shipping. The reported tanker attacks and the new warnings from maritime authorities suggest that the shipping piece of the deal is now one of its weakest points.
Diplomacy Is Still Moving, but the Ceasefire Is Not
CBS News reported Friday that President Donald Trump said the United States had agreed to keep talking with Iran, while also reiterating that the ceasefire is “over.” CBS also cited sources saying the U.S. and Iran remain in active indirect conversations through Qatari mediators.
Those talks are now happening against the backdrop of fresh U.S. strikes, Iranian retaliation, and competing claims over who controls passage through Hormuz. CBS reported that Iran’s Revolutionary Guard Corps fired on three commercial vessels in Omani territorial waters and has sought to charge ships fees for using the lane, a move Washington rejects.
The Bigger Risk
The immediate danger is to crews and ships still near the waterway. The broader danger is that Hormuz becomes a bargaining chip while the ceasefire framework collapses around it.
The Guardian reported earlier this week that the U.S. struck dozens of targets around the strait after the tanker incidents, while Iran argued that vessels should use routes it approves. That dispute over control of the lane is now colliding with the UN maritime warning to stay away entirely.
For now, the new development is simple and serious: the crisis is no longer just about whether Washington and Tehran can keep talking. It is about whether one of the world’s busiest energy chokepoints is safe enough for ships to use at all.
