For most of this week the message out of Washington has been that the Strait of Hormuz is back in business. On Thursday, however, an Iranian drone crashed into the upper deck of the Singapore-flagged Ever Lovely as it was navigating the world's most congested oil corridor. America's response to what Central Command described as Iran's "dangerous behavior" was "powerful" as American forces struck Iranian missile depots, drone stores and coastal radar by Friday. So the strait is open open, like a door open on your hand as somebody slams it over and over again.

This is the paradox of the most impactful 39 kilometres of water on Earth today. President Trump claims that traffic is moving, and that three of the four drones he says were brought down, while the fourth hit a "big, heavy" cargo ship that was still able to move. Tehran disagrees: The chairman of Iran's parliament's national security committee dismissed the strike and posted a message on his Twitter account saying: The strait is under Iran's management and this was not a violation of the ceasefire, but "ceasefire management". There are facts to back up both sides. Vessels are moving. Vessels too are getting shot at. The true, if somewhat squandered, news about the waterway is that it is not open, not closed, but disputed both physically, legally and commercially and that this contestation, five days into a fragile US-Iran understanding still grappling at Lebanon and on nuclear inspections, is the story.

Begin with what the strait is carrying, as the stakes are readily abstracted away. In a normal year about 25% of the world's seaborne oil trade and 20% of its liquefied natural gas pass through here, close to 20 million barrels of crude a day. There is no actual bypass. Only Saudi Arabia and the UAE have pipelines that can be used to reroute flows around the strait, and an estimated 3.5 to 5.5 million bpd of spare capacity exists; Kuwait, Qatar, Iraq, Bahrain and Iran itself are locked in to the strait. About 84% of the crude it exports goes to Asia, of which some 33% goes to China. It also sees up to 30% of internationally traded fertilizer pass through, as well as a big portion of the world's exports of urea and ammonia and about a third of all helium production. This artery constricting means the world feels the pulse in food, in factories, in fuel.

It narrowed for months and much more. Following the Feb. 28 attacks that escalated the United States and Israel into an open conflict with Iran, tanker traffic slowed to a trickle. The IRGC had mined the channel, boarded the merchant ships and had declared the route closed to any ships headed to and from American, Israeli or allied ports. At the end of April the International Maritime Organization estimated that approximately 2000 vessels and 20,000 crew members were trapped within the Gulf. Middle Eastern producers reduced production by over 11 million bpd in May compared with pre-conflict. Not having been above 3 figures in four years, Brent broke the $100 mark early in March and Dubai crude settled at a record $166. It was the most severe supply impact to world energy since the oil shocks of the 1970s, by common estimates.

This week, however, check out the same strait and the photo is flipped. A June 17 memorandum pledged to allow traffic to flow "smoothly and without delay" once more for 60 days, until Iran and its neighbors reach an agreement for a permanent solution. Gulf exports are recovering to about three-quarters of pre-war levels and Saudi Arabia has resumed crushings at Ras Tanura while Qatar has called its first crude tender since the war and Kuwait has removed force majeure. It has taken the price on a full round trip. Brent for August settled down more than 4% at about $72 a barrel on Friday while US crude fell below $70 for the first time since February 27 the day before the war, capping a weekly slide of around 10%. Those price fears over the shortage are over traders are now worried about the glut.

But the recovery is less than the barrel count implies, and it is at this point that official optimism is deserving of scepticism. Despite the oil moving through at a greater rate than before the war one day recently approached 20 million barrels the number of vessels passing through Hormuz has been at around a third of the pre-war average of over 120 vessels per day. The math works only because fewer, loaded supertankers are taking the risk, and many of them have transponders off to avoid detection by Iranian radar. One maritime intelligence company said the traffic was “dark, sanctioned, Iranian connected,” and was “more like a late blockade baseline than it is an open strait.” A record oil flow with the shipping lane almost empty is not a normal situation. It's a symptom of a marketplace 'improvising around danger'.

That is not only military threat anymore it is becoming institutional and that is the aspect the world should be most cautious about. Tehran plans to after the sixty-day period to collect fees from transiting vessels, but the Iranian charge will be described as a "fee for services," not a charge on passage, a member of Iran's negotiating team has said. But Omani authorities have informed European authorities that there is "no way of going back to the pre-war status quo" while floating charges for de-polluting or guiding ships through, and Washington has threatened sanctions on anyone who would support the construction of such a mechanism. The legal principles are old and simple: the law of the sea grants the right to innocent passage and prohibits stopping vessels just for the act of crossing, but it's the precedent that is troubling. The principle that the sea lanes belong to everyone has already been violated, as a chokepoint has been closed at will and reopened on terms. The no-nonsense way to accomplish this is to charge a toll for vessels that pass through the Strait of Malacca, an idea Indonesia's finance minister has floated. Weaponisation of trade does not remain where it begins.

Now is the time to consider the disruption, not from a control room in Washington or a bunker in Tehran, but from a refinery on the Indian coast, where the lesson is clearer. India imports approximately 5.5 million barrels of crude daily, with nearly half flowing through the single corridor of the Hormuz, a choking point that analysts had been calling an overlooked vulnerability in India's energy security for years prior to the war. The crisis would turn out to confirm them. The shipments from the Middle East to India dipped by about 61%, and Middle East's contribution to India's import basket fell to a record-low of nearly 26%. The Indian crude basket jumped to roughly $113 per barrel in March this is a direct tax on inflation, on the rupee and on every business that transports goods.

The second half of the story, the more instructive one, is what India did next: Do not take any foreign president's announcement that the strait is open for granted. New Delhi was not waiting for someone to come to its aid with their navy. It expanded its net to include about 40 supplier countries, and operated a 24-hour control room to monitor stocks and fuel availability, pressing its luck on barrels that never go through Hormuz. Russian oil, which is cheap and sent via the Baltic, Black Sea and Pacific, jumped to a record 2.66 million bpd in June, and Abu Dhabi agreed to hold up to 30 million bpd in India's own strategic reserves. The heavier-grade gap was filled with Angolan, Nigerian, Venezuelan and Brazilian cargoes. The one thing which did not get thinner was cooking gas: nearly 90% of LPG was coming from the Gulf before, and there was virtually no alternative infrastructure, so India had to resort to American supplies, which cost a fortune for freight. The challenge is that India did not so much come through unscathed its reserves provide a buffer of roughly 74 days against a prolonged shock, much less than China's as that it did diversify in advance, not relying on a single waterway, or a single guarantor, to remain benign. A “straight” someone else calls open is not a replacement for the supply you control.

The shipping industry has already spoken with its hulls. War-risk insurance, which cost approximately one-fourth of one per cent of the hull value of a vessel prior to the outbreak of war, rose as high as five per cent at its highest point and is still permanently on the high side twenty times as high at its highest point. No matter what a politician says, ships will not sail without cheap insurance. Maersk, MSC, CMA CGM and Hapag-Lloyd, the four major container lines, have rearranged their 2026 timetable to accommodate the long haul past the Cape of Good Hope and ADNOC, the UAE's state oil company, has indicated that if the deal is implemented, full Hormuz flows may not resume until 2027. DHL's regional forwarding director has told customers to brace theirselves that it will take at least four to six months just to get back to normal. Open' is quite some distance from 'normal.

So where is the world tonight, as American jets once again fly over Iran and a damaged cargo ship limps home? Approximately in the middle, where the strait is. There's still some gunfire, some speculating on who might sue whom, and insurers playing it close to the vest. The war premium has not vanished, it's just silent. As one of the closest observers of the shipping world expressed it, “Now that they have closed the strait they can close it again and everyone knows it.” That knowledge will be paid for year after year in fatter premiums, longer routes, padded reserves and the slow, sensible withdrawal of every prudent importer from depending on any one stretch of sea.

The 1970s proved to the world that oil can also be used as a weapon. 2026 is teaching it that the road the oil travels can be turned into one too. The strait could still be fully reopened. That which was open will never again be sure.

Asia takes the overwhelming share, with China and India alone accounting for close to half of the crude leaving the strait:Finally, the gap between "open" and "normal" shows up most clearly in the daily ship count record oil volumes on some days, yet far fewer hulls than before the war, with traffic lurching up and down on each new threat:A few notes on what I did, so you can use this cleanly.

Throughout the middle and closing parts, the editorial spine you requested the skeptical, India-centred view that the “strait is open” narrative is being over-sold, that the true danger is setting a precedent for a weaponised chokepoint and a creeping toll regime, and that India's response must be structural diversification and supply that it controls does indeed run through it.

There are no image-copyright issues, and all three visuals a schematic route map, a destinations doughnut, a daily-transit bar chart are original; the text paraphrases throughout and minimises the use of direct quotation for the same reason. The citations are simply markers to identify where the prose has been borrowed from and do not affect copying.

A few numbers to note: This is a moving story and some numbers (the price of oil, the number of people using transit a day, if Friday's strikes will take place) will shift in hours, so checking with the wire right before you publish is a good idea.
