The ceasefire declared only 24 hours ago and oil is already plummeting below $90 and missile fire is being fired over the gulf. The situation changed overnight and very few people were prepared for it.

Somewhere over the Strait of Hormuz, some time after midnight, local time, an AH-64 Apache crashed. Both pilots escaped; in a remarkable first, by an unmanned 24-foot vessel instead of a crewed rescue helicopter. That's just one of the reasons why you know this waterway has become more militarized since February. The bigger story, however, has nothing to do with the rescue, or even the helicopter. It's who that Apache opened up in the hours that followed, and what it might unravel in the days ahead.

In less than 24 hours, the United States made so-called "self-defense strikes" on Iranian air defense installations, radar sites and ground control stations near the strait, which it said were "proportional. In response, Iran, via the Islamic Revolutionary Guard Corps, attacked U.S. military bases in Bahrain, Kuwait, and Jordan, including the F-35 hangars at the Al-Azraq airbase. Jordan managed to intercept five Iranian missiles. Kuwait rushed to fortify its air defenses. Air raid sirens began blaring throughout Bahrain. This was a very noisy night for a war that was supposedly on hold.

Washington has long been brooding about a full-scale deal with Tehran to settle the conflict, open up the Hormuz strait, and in principle slow down Iran's nuclear program in return for easing sanctions. Trump himself had indicated just a day prior to the helicopter incident that a deal was "two or three days" away. Trump told reporters Monday there was "a good chance" of something imminent, despite some Iranian ballistic missile fire and Israeli counterfire, which rattled the just-restored ceasefire. He persuaded oil markets to believe him and that's why Brent sank below $90 per barrel for the first time since mid-April.

Then down came the Apache, and the logic of deal making ran headlong into the logic of deterrence. In a phone interview with The Wall Street Journal, Trump initially dismissed the incident, saying it was "not a big deal" because the pilot was "fine. However, he was later convinced by Defence Secretary Pete Hegseth and General Dan Caine that not to do so would signal something completely different. So in went the strikes proportional to help the conversation flow, forceful to please the hawks, and baffling to keep everyone guessing about what comes next.

The economic situation that often goes under the geopolitical radar. The Strait of Hormuz was shipping some 20 million barrels a day in total (crude, condensate and LNG) until the war erupted on February 28, accounting for some 20 percent of the world's oil supply. In its June 9 report, the U.S. Energy Information Administration reported that the strait has been effectively closed to normal commercial traffic for more than three months. The average price of Brent crude in May was $107 per barrel, which was $10 below its April level but still well above prices of pre-war days. At the current rate of drawdown, OECD oil inventories will fall to their lowest level since 2003 by December.

Meanwhile, demand for oil on the global market has been hit unexpectedly. The EIA now projects that demand will decline by 1.1 million b/d in 2026, a sharp turnaround from the previous forecast of demand rising by 1.2 million b/d in February. But in Asia, where the impact of the shutdown has been most acute, data is not always available what is available indicates that the impact of the demand destruction is worse than the initial models had assumed. India's import bill has increased to a huge amount. Both Japan and South Korea, which are high-consumers of Gulf crude, have been competing for other supplies from Africa and the Americas at a high price. Assuming Hormuz reopened tomorrow, U.S. Energy Secretary Chris Wright said on Tuesday it would take “many months” to get flows back to normal.

Global oil demand impact: 2026 forecast revisions (million b/d change)

This analysis was derived from U.S. Energy Information Administration data on the June 9, 2026, Short-Term Energy Outlook (STEO).

If we do the bombing, a lot of people are going to be killed, who wants to be responsible for doing that? I don't, but you'll not have the strait open for months either. Donald Trump, Monday evening, hours before the USA ordered strikes on Iran.

Escalation nobody wanted (but everyone half-expected)

But Iran's foreign ministry was forthright Tuesday, claiming the strait of Hormuz was not international waters but "common" to Iran and Oman, and that any foreign military moves near Iranian territory "are at constant risk. That framing matters. It marks Tehran's attitude that the downing of the helicopter was not aggression but a proper reaction to an unwelcome military presence, and that while this may sound provocative in Washington, it resonates in the region's non-aligned bloc. But the Arab League's condemnation of Iran's later attacks on Kuwait, Bahrain and Jordan was uncompromising and immediate, and Tehran's policy has been to isolate itself from its neighbors as it has played out this conflict.

Western capitals were skeptical of the IRGC's assertion that it removed 21 targets, four of which were an F-35 hangar. The initial U.S. assessment indicates that almost all Iranian missiles and drones were destroyed and no immediate damage to U.S. personnel occurred. This is a militarily reassuring fact and it has diplomatic implications. Iran displayed intent and reach. Washington showed defensive skills. That "swipe" wasn't technically a "win" for either side in any obvious way that's why the deal-making can, in theory, continue.

The Netanyahu Calculus and the Zamir Signal

As the U.S.-Iran exchange was all the news the next day, something else was going on in Israel. During a visit to troops at a military exercise, IDF Chief of Staff Eyal Zamir told them outright that the strikes Israel had carried out on Iran on Monday were "preparation for a much more significant and severe blow. The IDF has a "state of immediate readiness" to return to full scale fighting, he added. This wasn't the routine military jargon. Netanyahu, however, was said to have agreed a much more ambitious strike plan, which was ultimately scrapped after Trump reportedly delivered an ultimatum that Israel would be "on its own" if it went ahead with the strike.

It is a tension that is good to sit with. The U.S. at the same time prevented its closest partner in the region from getting out of hand, struck Iran itself for the helicopter and is, in principle, still seeking a nuclear deal. Iran's parliament speaker, Mohammad Bagher Ghalibaf, a hardliner who has always been more inclined to confrontation than compromise, had previously threatened Tehran would "switch to what we speak best" if Washington broke any negotiated commitment. But what will be deemed a violation and who will be able to enforce it is exactly the sort of grey area that sparks escalations of ceasefire violations and open wars.

The greater issue with "Proportional"

The grammar of this war is odd: messages of commitment, but not escalation. The word "proportional" has been featured in nearly all CENTCOM statements since February. But proportionality is at work here, doing a tremendous job. It's a military doctrine, a diplomatic signal, a domestic political message, and even an insurance policy against being sucked further into a conflict that no one's economy can afford.

If the war continues, OECD oil stocks are likely to reach their lowest level since 2003 by year-end, the EIA says. It's not an abstraction. It's heating fuel supplies for the Northern Hemisphere winter, manufacturing disruptions in Germany and South Korea, and aviation fuel surcharges, which add to airfare inflation, and petrochemical feedstock shortages, which impact plastics, pharmaceuticals and fertilizers. This week's events were on top of a downward revision of 0.8 percentage points already made by the IMF for growth in the world in 2026. The world economy is far from being able to tolerate $107 oil, or the potential return to open fighting that might see prices move back to $115 or more.

Meanwhile, a compromise upon Iran's nuclear programme, the litmus test at the end of this tunnel, is very hard to come by. Washington has called on Tehran to hand over its stockpile of highly enriched uranium, which is suspected of having been stored in underground facilities and partially destroyed in U.S. airstrikes last June that last 12 days. Iran outright rejects and is requesting sanctions relief and access to its frozen assets even before an agreement is finalised. Iran has offered only a promise to dilute, not to transfer, its uranium stockpile, and that is a huge shift from the state of the talks a year ago, but still may not satisfy critics in Washington, the New York Times reported on Wednesday. If it fails to resolve the nuclear issue for any real length of time, this war will have been bought in large part with military and economic expense for much less than advertised.

Ceasefire optimism cannot sustain the world's oil markets. diplomacy eventually provides a real deal or the pretence of having one becomes too expensive to maintain.

What Happens Next

On Wednesday, Iran's foreign minister, Abbas Araghchi, issued a warning to the world: "Leave our region if you want to be safe. A number of times, the speaker of Iran's parliament has spoken of "other fluencies" as a code word for military action. The IRGC has stated that it has achieved 70% success rate in its strikes despite the U.S. estimates of almost complete interception. Both stories are for the domestic audience. Both are only partial truths. What they share is a resolve to prove that the presence of the U.S. military in the Gulf is not cost free.

The Arab League's unequivocal criticism of Iranian attacks on Kuwait, Bahrain and Jordan is a telling sign: Tehran's regional isolation is growing as its proxies in Yemen and Lebanon are still being deployed. The Gulf monarchies are highly vulnerable to another disruption of the Hormuz, with their export revenues, financial system liquidity, and even their social contracts with potentially restless populations all relying on the resumption of flows. That puts them, by proxy Washington, in a position to prod both sides toward a real deal, not endless choreography of calibrated strikes.

According to all reports, the Apache crash Tuesday morning over the strait in the darkness was a routine patrol. Two pilots got wet. They were recovered with a drone. Trump shared a post on Truth Social. Then the entire tenuous balance of ceasefire, deal making, and controlled escalation wobbled, if it didn't outright tilt over. Whether this architecture holds or the next proportional response is not the one that holds will be the question that the coming 72 hours will answer.
