The fragile U.S.-Iran ceasefire is unraveling further this week after a new round of tanker attacks in the Strait of Hormuz prompted President Trump to declare the truce "over" and warn of additional strikes, while Iranian officials insist Tehran will not relinquish what it calls its authority over the strategic waterway.

What Sparked the Latest Flare-Up

The escalation began on July 7, when three commercial tankers, including the Qatari-flagged LNG carrier Al-Rekayyat, were struck near Oman's coast while transiting the Strait of Hormuz. Britain's Maritime Trade Operations center confirmed a tanker was hit by a projectile off the coast of Oman in the southern part of the strait, and sources told Reuters it was struck by an Iranian missile, which caused a fire in the engine room. A separate vessel was also reportedly hit by a drone in what may have been a third attack on commercial shipping that day.

In response, President Trump surprised NATO leaders he was meeting with in Turkey when he ordered a series of retaliatory strikes on Iran and revoked a license that had allowed Tehran to sell oil on the world market. Days later, U.S. Central Command said it launched a barrage of strikes hitting over 80 Iranian targets with precision munitions, including air defense systems, command and control networks, coastal radar sites, anti-ship missile capabilities, and more than 60 Revolutionary Guard small boats in and near the strait.

Trump Warns of More to Come

Speaking from Ankara, where he is attending a NATO summit, Trump made clear the U.S. response isn't finished. He threatened to launch another "big attack" on Iran and warned the U.S. Navy could reimpose the naval blockade of the Strait of Hormuz that had been lifted after last month's memorandum of understanding. Asked whether more strikes were coming, Trump told reporters, "there's not a thing they can do about it," adding, "the answer is probably."

Trump also escalated his rhetoric toward Iran's oil infrastructure directly. He confirmed U.S. forces struck Kharg Island — which handles roughly 90% of Iran's crude exports — overnight, while sparing its oil facilities, and floated the idea that the U.S. could take over the island entirely. In a Truth Social post referencing the tanker attacks, Trump warned, "If it happens again, it will get much worse!" Vice President JD Vance echoed the warning, telling reporters on July 8 that "if Iran tries to close the strait down, there's going to be a response."

Iran's Position: It Won't Give Up Control of the Strait

Iranian officials have responded defiantly, framing their actions as enforcement of the terms of the ceasefire agreement rather than aggression. Tehran has insisted it will not give up control over the Strait of Hormuz waterway even as U.S. attacks and the withdrawal of Iran's sanctions waivers threaten the fragile truce. The dispute centers on Article 5 of the memorandum of understanding, which states Iran will make efforts for the safe passage of commercial vessels through the strait — language Iranian officials argue gives Tehran authority to manage traffic, while the U.S. maintains it only obligates Iran not to impede transit.

Iranian parliamentary spokesman Ebrahim Azizi captured Tehran's stance bluntly, writing online that officials should "recognise the new and Iranian order in the Strait of Hormuz" as the only acceptable path forward. Iran's Revolutionary Guards said in the prior week that they were taking measures to control traffic in the strait and that violating vessels would be dealt with more firmly than before. Meanwhile, Iran's Deputy Foreign Minister accused Trump of weakness rather than strength, saying his renewed threats amounted to "an admission of the failure of a policy built on brute force, sanctions, and threats for years, which could not bring the Iranian nation to its knees."

Regional Fallout and Shipping Disruption

The renewed attacks have had immediate humanitarian and logistical consequences. The United Nations' International Maritime Organization paused efforts to evacuate stranded sailors through the strait after a vessel was hit by a projectile, with the agency's Secretary General saying seafarer safety "remains paramount" and that the evacuation plan would stay on hold until safety could be confirmed. Gulf states have largely rallied behind the U.S. and against Iran's actions — Kuwait objected strongly to Iranian strikes on its territory, saying they undermined regional de-escalation efforts, while Qatar and Saudi Arabia have condemned the tanker attacks as violations of international maritime law.

Why It Matters for Global Oil Markets

The Strait of Hormuz remains the world's most consequential energy chokepoint, with roughly a fifth of the world's oil supply passing through it. Every attack, threat, or blockade rumor sends immediate ripples through crude prices, and the current standoff shows no sign of a durable resolution. Notably, despite the conflict, Iran has reportedly been earning nearly double its usual oil revenue during the war, as strikes have so far failed to fully halt its energy exports even as global prices rise — a dynamic that complicates U.S. efforts to use economic pressure as leverage.

With both sides trading threats and neither showing willingness to back down publicly, analysts warn the coming days will be critical in determining whether the memorandum of understanding can be salvaged — or whether the Strait of Hormuz standoff tips into a broader, more sustained conflict.
