JUST IN: During a March 31 briefing, President Donald Trump dissolved the foundational guarantee of the post-1945 energy order. “We’ll be leaving very soon,” he said. “What happens in the Strait, we’ll have nothing to do with.” He estimated two to three weeks. He added that if France or any country wants oil, “they’ll go right up through the Strait and they’ll be able to fend for themselves.” He said the strait will reopen “automatically” once the US leaves. Then the S&P 500 closed up 2.9 percent, its largest daily gain since spring 2025.
The market celebrated. Understand what it celebrated. Since 1945, the United States has guaranteed freedom of navigation through Hormuz. The Fifth Fleet, the carrier rotations, the basing agreements with Bahrain, Qatar, and the UAE, all exist for this purpose. The implicit promise that 20 percent of the world’s oil would flow without interruption through a 39-kilometre channel has underwritten every energy contract and every GDP forecast for eight decades. In 33 seconds, the president withdrew the promise. Equities rallied.
The strait was open on February 27. Operation Epic Fury closed it on February 28. Traffic collapsed 95 percent. Oil hit $107. Insurance surged 1,000 percent. The IRGC built a toll system, collected yuan, and banned American ships from the waterway American taxpayers spent 80 years guaranteeing. Now the president who ordered the strikes is telling the world the crisis is not his problem. He started the fire, sold the water, told the neighbours to buy American fuel, and is leaving the building while the fire burns.
This is not the first time Trump has used exit rhetoric as leverage. “Fire and fury” on North Korea led to summits. Mexico tariff threats led to concessions. Soleimani was real but limited. The pattern fits: threaten escalation through April 6 while signalling departure. Assets remain forward. Abraham Lincoln strike group in the Arabian Sea. Three LCS in the Gulf. Marine units staged. No drawdown orders issued. The rhetoric says exit. The fleet says stay.
But here is what makes this time structurally different from every previous Trump bluff. In North Korea, the status quo ante was preserved. No war, no change. In Mexico, tariffs were withdrawn. The baseline held. In each case, the pre-threat equilibrium was restored. This time, the pre-threat baseline is permanently gone. The strait was open before the war. It is closed now. If Trump exits in two to three weeks without reopening it, the baseline has permanently shifted. The US will have launched the most expensive military operation since Iraq, achieved every conventional objective, and left the waterway in worse condition than it found it. The bluff pattern has always restored equilibrium. This would be the first time it destroys it.
Ghalibaf said it from the other side: “The enemy has now set its operational ambition to opening a strait that was open before the war began.” Trump and Ghalibaf agree on the facts. They agree the strait was open. They agree it is closed. They disagree only on who owns the consequence. And in 33 seconds, Trump answered: nobody does.
The guarantee is withdrawn. The strait is still closed. The market went up. That is the epitaph of Pax Americana’s energy doctrine, written in a press briefing and priced in by closing bell.
