Closed, and Still Flowing

Back in March, with Brent up roughly 40% and Hormuz declared shut, the comparison everyone reached for was 1973. We argued it was the wrong map. Oil intensity has more than halved since then, the US is now the world's swing LNG exporter, and a shock that would have crippled the 1970s economy lands very differently today. Three months of data are in. Here's how it actually played out.

The headline number that matters isn't the price of Brent. It's the gap between what Iran announces and what the tankers actually do. On June 17 the US and Iran signed a 14-point memorandum: a 60-day toll-free ceasefire, mines cleared, the US blockade lifted, sanctions waivers for Iranian exports. Three days later Iran's IRGC re-declared the strait closed over Israeli strikes in Lebanon. Both things are now true at once: a military closure and a diplomatic reopening, running side by side, while supertankers go dark and then switch their transponders back on.

A chokepoint only matters if someone is actually willing to choke. So far, no one with oil to sell has been.

Who actually won the shock?

This is the part the panic missed. A New York Times analysis of shipping through early May found the biggest beneficiaries weren't in the Gulf at all. The United States picked up around $50B in extra export revenue; Russia added more than $15B. The Gulf producers that couldn't bypass the strait — Iraq, Kuwait, Qatar, the UAE — lost revenue. Iran, which controls access to the waterway, gained. The crisis didn't destroy supply so much as redistribute the rent, away from the exporters sitting behind the chokepoint and toward everyone selling around it.

• Roughly a quarter of the world's seaborne crude normally moves through Hormuz
• Kpler logged ~20 tankers in a single day last week — the most since June 2, but still below the prewar 100-plus daily
• The central channel remains mined; mine-clearing is a ceasefire term, not a finished fact
• After the 60-day toll-free window, Iran wants talks with Oman and the Gulf states on who administers — and tolls — the strait

The $200-a-barrel scenario that traders floated in March never arrived. What did arrive is subtler and probably more durable: a war premium that didn't vanish but relocated — into insurance rates, into freight, into the unresolved question of who controls the toll booth once the ceasefire clock runs out. The strait can be "closed" and full at the same time. That contradiction, not the price spike, is the real story of 2026.
