Iran’s Islamic Revolutionary Guard Corps seized two container ships in the Strait of Hormuz on Wednesday, less than 24 hours after President Donald Trump announced an indefinite extension of the U.S.-Iran ceasefire to allow peace talks to continue. The move marks a sharp escalation in tensions despite diplomatic efforts to de-escalate the conflict that began in late February.
The seizures occurred shortly after Trump declared the ceasefire would be extended so negotiations could proceed, according to multiple verified reports. Iran’s Revolutionary Guard Navy stated in a statement carried by state media that it had seized the ships for what it claimed were maritime violations and transferred them to Iranian shores. CNBC could not independently verify the claim.
U.K. Maritime authorities had earlier reported that two ships were attacked in the Strait of Hormuz, with Iranian media later indicating a third vessel had also been targeted. The United Kingdom Maritime Trade Operations (UKMTO) center said a vessel reported being fired upon about 8 nautical miles off the coast of Iran at 8:38 a.m. London time (3:38 a.m. ET).
The Strait of Hormuz remains a critical global chokepoint, typically transiting roughly one-fifth of the world’s oil and gas supplies. However, commercial shipping traffic has been severely disrupted since the war began, with hardly any ships traversing the waterway in recent weeks.
Both the United States and Iran have claimed the strait is now “completely open,” but serious questions persist about when traffic will return to pre-war levels. On Friday, Iranian Foreign Minister Abbas Araghchi announced a deal regarding the strait, stating that passage for all commercial vessels was declared completely open for the remaining period of the ceasefire on the coordinated route already announced by Iran’s Ports and Maritime Organisation. Trump echoed the sentiment, though he acknowledged the U.S. Blockade of Iran’s ports remains in place.
Financial markets reacted swiftly to the earlier announcement of openness, with oil prices dropping about 9% and U.S. Crude trading at levels not seen since the initial days of the war. Brent crude futures with June delivery traded 0.5% higher at $99.03 per barrel on Wednesday, paring gains after briefly surpassing $100. U.S. West Texas Intermediate futures with June delivery traded up 0.5% at $90.13.
The White House said Trump remained “satisfied” with the naval blockade despite Iran’s actions, underscoring the divergence between Washington’s diplomatic posture and Tehran’s military response. Iran has insisted that lifting the U.S. Blockade is a prerequisite for meaningful negotiations, although Washington has maintained the blockade as leverage.
Diplomatic efforts to revive talks have faced repeated setbacks, including Iran’s earlier demand that Israel halt military operations in Lebanon before agreeing to strait access. An agreement between Israel and Lebanon eventually allowed Iran’s foreign minister to announce the new deal, but the latest seizures suggest Tehran may be using military pressure to strengthen its negotiating position.
Analysts warn that the pattern of ceasefire extensions followed by Iranian military actions risks undermining confidence in the negotiation process. The U.S. Has framed the ceasefire extension as a opportunity for dialogue, but Iran’s seizure of vessels indicates it may be testing the limits of American patience.
The situation remains fluid, with no immediate indication of when or if the seized vessels will be released. Maritime security experts continue to monitor the Strait closely, as any further disruption could have significant implications for global energy markets.
