The fragile US-Iran ceasefire signed just weeks ago is unraveling. On Monday, Washington and Tehran each claimed control of the Strait of Hormuz after a weekend of strikes, missile alerts, and retaliatory attacks across the Persian Gulf [1]. The escalation has thrust the world’s most important energy chokepoint back into the center of a conflict that had already killed thousands and triggered a historic oil shock.
The immediate trigger was Iran’s strike on a Cyprus-flagged container ship, the MV GFS Galaxy, as it transited the strait off the coast of Oman on Sunday [4]. The US Central Command (CENTCOM) responded with a wave of strikes it described as aimed at “degrading” Iran’s ability to threaten shipping, hitting dozens of targets including air-defense systems, coastal radar sites, missile and drone capabilities, and small boats [1][2]. Hours earlier, the US had struck some 140 Iranian military sites in a far heavier round of attacks than in previous exchanges over the past week [1]. President Donald Trump told NBC’s “Meet the Press,” “We bombed the hell out of them last night” [1].
Iran answered in kind. The Islamic Revolutionary Guard Corps (IRGC), which controls Iran’s ballistic missile arsenal, launched missile and drone attacks against US bases and American-aligned hosts across the region, including Bahrain, Kuwait, Jordan, Qatar, and the United Arab Emirates [1][2]. Qatar, a key mediator in the ceasefire talks, had not been attacked since April; the UAE had not been targeted since May [2]. In Jordan, the military said it shot down four Iranian missiles with no casualties or damage [1]. Bahrain, home to the US Navy’s 5th Fleet, sounded missile-alert sirens three times on Monday [1]. Iranian state media reported at least one person killed and four injured in southwestern Iran [2].
Both sides are now asserting sovereignty over the strait. CENTCOM declared, “The Strait of Hormuz is a vital maritime corridor for global trade. Iran does not control it” [1]. The IRGC rejected that claim, calling the waterway “our territory” and vowing not to allow “a rogue and child-killing army from the other side of the world” to interfere [1]. Iran’s Persian Gulf Strait Authority warned that vessels using unauthorized routes would not be covered by safe-passage guarantees [4]. Tehran has effectively declared the strait closed; Washington insists it remains open [2].
The confrontation comes barely a month after the two sides signed a 14-point memorandum of understanding on June 17, brokered largely by Pakistan and Qatar, that was supposed to halt military operations on all fronts, lift the US naval blockade, and open the strait [3]. Under that interim deal, Washington and Tehran were given 60 days to resolve the thorniest remaining issue: Iran’s stockpile of highly enriched uranium and its atomic program [3]. Instead of moving toward those talks, the parties are now roughly halfway through that window and trading fire.
UN Secretary-General António Guterres warned that “a return to full-scale hostilities would have catastrophic consequences” [1]. His concern is grounded in the strait’s outsized economic role. In peacetime, roughly one-fifth of globally traded crude oil and liquefied natural gas passes through the narrow waterway, and about 130 vessels transited daily before the war began [1][4]. Since Tehran effectively closed the strait after the US and Israel launched strikes on February 28, shipping has collapsed. Maritime intelligence platform Windward tracked just six crossings between 18:00 GMT Thursday and 06:00 GMT Friday, down from 18–22 daily crossings earlier this month; nine crossings were recorded in the following 12-hour window, four of them Iranian-flagged [4].
Markets reacted immediately. Brent crude futures for September delivery rose more than 4 percent to $79.26 a barrel as of 05:00 GMT on Monday, the highest since June 22 [4]. US-traded crude also climbed 4.3 percent to $74.50 [2]. Major Asian stock markets fell, with Japan’s Nikkei 225 down more than 2 percent and South Korea’s Kospi plunging more than 8 percent [4]. The price surge is modest compared with the war’s earlier peaks—Brent briefly topped $120 a barrel in late April—but it signals that traders no longer believe the June deal guarantees stability [1][4].
Analysts are divided on whether the latest spike will persist. Mukesh Sahdev, founder of XAnalysts, expects Brent to remain in the upper $70s through August and September amid geopolitical uncertainty, with occasional spikes [4]. Fabien Yip of IG noted that oil’s return toward pre-war levels in June reflected a “best-case outcome” priced into the fragile arrangement, and last week’s re-escalation “exposes how fragile that assumption was” [4]. Still, Yip and others argue a repeat of the April spike is unlikely because demand remains sluggish and OPEC+ output increases and stranded-tanker releases are adding supply to an already oversupplied market [4].
Diplomatically, the picture is murky. Trump suggested last week that the interim deal was “over,” but also said talks would continue [1][2]. Mediators including Pakistan, Qatar, and Egypt are still trying to revive the process [1]. Pakistan’s foreign minister spoke by phone with Iran’s top diplomat on Sunday and urged de-escalation on both sides [1]. Oman, long an interlocutor between Tehran and the West, summoned an Iranian diplomat to protest the attack on shipping in its waters [1]. Yet Iran’s new supreme leader, Ayatollah Mojtaba Khamenei—who succeeded his father after the latter was killed in the war’s opening strikes—vowed in his first statement since the funeral that Iranians would avenge the killing [1].
The deeper problem is that the June deal left the most consequential questions unresolved. Iran retains a ballistic missile arsenal and enough highly enriched uranium to build several nuclear weapons if it chose to do so [3]. The US wants that uranium removed; Iran insists on keeping it [3]. Israel, which joined the US in launching the war on February 28 and has pressed its own campaign against Hezbollah in Lebanon, did not immediately comment on the interim agreement and has repeatedly acted in ways that nearly derailed the talks [3]. With the strait now a live battlespace again, the 60-day negotiating window risks becoming a countdown to wider war rather than a path to peace.
For the rest of the world, the lesson is stark: a single waterway still holds extraordinary leverage over global energy prices, inflation, and maritime security. The US and Iran may both claim control of the Strait of Hormuz this morning, but neither has demonstrated the ability to keep it reliably open or closed. Until one of them does, volatility is the only certainty.
