President Trump announced on Truth Social Sunday morning that the US Navy will impose an immediate blockade on all shipping through the Strait of Hormuz. The order came hours after Vice President JD Vance left Islamabad without a deal, ending 21 hours of face-to-face negotiations with Iranian officials.
"Effective immediately, US Navy will BLOCKADE any and all ships," Trump wrote. He ordered the Navy to intercept any vessel that had paid transit tolls to Iran during the ceasefire and to begin destroying the sea mines Iran planted across the strait in March.
Why the talks failed
The negotiations collapsed over two core issues. Iran demanded that any deal recognize its right to control shipping through the strait, including the collection of fees from passing vessels. Washington refused. On the nuclear front, American negotiators demanded Iran give up its enriched uranium stockpile. Tehran called that a non-starter.
Vance said the US delegation left behind what he described as a "final and best offer," leaving a narrow window for diplomacy. The 14-day ceasefire agreed on April 8 remains technically in effect until April 22, though the blockade order casts serious doubt on whether it can hold.
Market reaction
Futures markets are closed for the weekend, but traders are bracing for a sharp move higher when CME and ICE trading resumes Sunday evening. Both benchmarks closed Friday at $96.57 (WTI) and $95.20 (Brent). Goldman Sachs has warned that Brent could average $120 per barrel through Q3 if the strait remains closed.
What it means
Trump's order transforms the Hormuz situation from an Iranian blockade into a contested military zone where both navies are actively interdicting shipping. The directive to destroy mines adds an active combat dimension that could trigger further escalation. Traders are bracing for a volatile week ahead.
