On April 17, 2026, President Trump posted on Truth Social that “Iran has just announced that the ‘Strait of Iran’ is fully open and ready for full passage. Thank you!”
Two things about that post. First, it’s called the Strait of Hormuz. It has been called the Strait of Hormuz for centuries. It is one of the most strategically important waterways on the planet. The president of the United States — the man who started a war over this waterway — called it the “Strait of Iran.” He later corrected himself, but the original post stood long enough for the entire world to see it.
Second, the announcement he was celebrating — Iran’s opening of the strait to commercial vessels — collapsed within 24 hours.
What Actually Happened
On the morning of April 17, Iranian Foreign Minister Abbas Araghchi announced on X that “the passage for all commercial vessels through Strait of Hormuz is declared completely open for the remaining period of ceasefire, on the coordinated route as already announced by Ports and Maritime Organisation of the Islamic Republic of Iran.”
Markets reacted instantly. Brent crude crashed over 10% to $88.73 a barrel. West Texas Intermediate fell 10.8% to $84.44. It was the biggest single-day drop in oil prices in six weeks.
Earlier in the week, WTI had been trading above $105 a barrel. The Hormuz announcement wiped out weeks of war premium in a single session. But the underlying situation hadn’t changed: the U.S. naval blockade of Iranian ports remained in effect, the Iran ceasefire was set to expire April 21, and neither side had agreed to a deal.
Trump followed up on Truth Social, clarifying (this time using the correct name) that the U.S. blockade on Iranian shipping would “remain in full force and effect as it pertains to Iran only, until such time as our transaction with Iran is 100% complete.” In other words: the strait is “fully open” unless you’re Iran.
Iran’s Response: Re-Close Everything
By April 18, Iran reversed course. Iran’s military leadership announced that it had regained control of the Strait of Hormuz in response to the continued U.S. naval blockade. Tehran said the U.S. had violated the spirit of the ceasefire by refusing to lift restrictions on Iranian ports.
It didn’t stop at words. The Indian-flagged VLCC Sanmar Herald was attacked by Iranian gunfire from two boats in the Strait of Hormuz, despite having received prior clearance to pass. A container ship reported damage from a rocket attack off the coast of Oman.
Iran’s message was unmistakable: if the U.S. blockade stays, the strait stays closed. And they’re willing to fire on ships to enforce it.
Trump’s Response From Air Force One
On the flight back to Washington Friday night, Trump was asked what happens if the ceasefire expires without a deal. His answer: “Maybe I won’t extend it. So, you have a blockade and unfortunately, we’ll have to start dropping bombs again.”
He then added, “I think it’s going to happen,” referring to a deal. Which is what he’s been saying for weeks. The ceasefire expires Wednesday.
The Pattern
This is the same cycle that has played out since the war started on February 28: Trump claims progress that doesn’t exist, markets react, reality reasserts itself, and the underlying situation gets worse. He said the war was “very close to over” on April 15. He claimed China agreed to a deal that China never confirmed. Now he declared the strait “fully open” and it was re-closed within hours.
The president is treating the largest energy crisis since 1973 like a Truth Social content strategy. The strait is not open. The blockade continues. Ships are being attacked. And the ceasefire expires in four days.
