Wanting Out Is Not Getting Out

Part two of three. Part one showed why both sides need the war to end. This one is about the distance between needing it and having it.

On July 7, two tankers were hit in the Strait of Hormuz. One was a gas carrier, and the first reports said it was at risk of catching fire. Qatar said Iran had done it. It was not the first time in the young life of the peace deal. A tanker was struck in late June, and on July 4 four more were turned back into the Gulf by an Iranian Revolutionary Guard warning over the radio, ships to pass only on Iran’s terms and Iran’s route.

Every one of those days came after the framework agreement, after the United States Treasury reopened the door for Iranian oil, after American and Iranian negotiators sat in Doha and called the talks positive. On paper, the war was ending. On the water, a projectile could still find a hull, and kept finding one.

Part one of this series explained why the oil market is right that Washington and Tehran both need this war over. This part is about the harder half of the sentence. Needing a war to end and ending one are different problems, and the gap between them is not diplomatic. It is physical, it is strategic, and it is measurable. The reason the oil price and the shipping lane disagree is that they are looking at two different things, and the shipping lane is looking at the part a signature cannot touch.

Mines don’t read agreements

Start with the thing sitting on the seabed.

Sometime in the spring, according to United States Central Command, Iran seeded the Strait of Hormuz with naval mines. In April, the US Navy began the slow work of clearing them, sending destroyers through and dragging sonar-equipped drones across the bottom. The scale of that job is the tell. By an analysis in the Naval Institute’s Proceedings, opening the strait to two-way oil traffic means clearing two channels, each about 2,000 yards wide, across roughly 200 square miles of seabed. And the Navy is doing it short-handed. It retired its last four dedicated minesweeping ships from the region in September, leaving a thin substitute of other vessels to cover the gap.

Here is the point that the oil market, reading statements from a trading desk, cannot price. A mine does not know there is a deal. It was placed by a government that may now sincerely want peace, and it will sit there, live, until a diver or a drone removes it one by one, no matter what anyone signs. The intent that laid it has moved on. The threat has not.

Game theorists have a name for this, and it is the second gear of this series. They call it the commitment problem. A deal can fail even when no one is lying, because a promise made today cannot bind the world of tomorrow. Two parties can mean every word of a peace and still be unable to deliver it, because the thing that has to change is not their intention but a thousand separate hands, and no signature reaches all of them at once. The mines are the commitment problem you can photograph. So is the man with the radio. Tehran’s negotiators can sign in Doha and mean it, and a Revolutionary Guard commander in a fast boat off Bandar Abbas can still turn four tankers around the same week, because the peace has not yet reached him, and may not for a while.

Two conversations about the same strait

Picture a husband and wife at the end of a long day. He asks what is for dinner. She says her mother is coming Sunday. Both are talking, both make sense, and they are having two completely different conversations. The oil market and the insurance market are doing the same thing over the Strait of Hormuz.

The oil futures market answers one question: will the barrels flow? Remember that futures are contracts about a future date, so the price everyone quotes is a bet on tomorrow’s supply, and at reading supply it is the finest instrument ever built. It has looked at the deal and ruled the war over. But whether one ship crosses one strait without hitting a mine nobody has found yet is a different question, and the oil market is out of its depth on it. Charlie Munger spent fifty years telling investors to notice exactly this, the moment a question leaves the field you actually know. Naval mines are not a supply-and-demand field.

That question belongs to the people who do nothing else: the marine war-risk underwriters, who insure one hull for one crossing. Whether a ship comes home is the only thing they price, and they are not standing down. Two markets, two questions, two answers. The oil market knows whether the world will be short of oil. The underwriters know whether this ship, this week, survives the water. Only one of those questions is about the strait, and the strait is all water.

You can watch the split inside a single number. Oil has its own fear gauge, the price traders pay for protection against a wild swing, and it spiked above 120 in March at the war’s peak. By early July it had fallen back to around 40, most of the way down, but not home, because before the war it sat near 30. Even the oil market, in the part of itself that quietly buys insurance, is still paying up for the chance that this goes wrong.

The recovery is the Navy’s, not the market’s

There is one more thing the transit numbers hide, and naming it corrects an easy misreading.

Traffic through the strait has come back, and the headline version of that recovery reads as confidence returning. Look closer and it is something else. A majority of the transits since the spring have run dark, with transponders switched off, roughly 57 percent by the count of the analytics firm Vortexa, peaking near 65 percent in May. The instinct is to assume this is the sanctioned shadow fleet, the operators who never cared about the rules. It is not, mostly. Much of that dark tonnage is ordinary Gulf crude, Saudi and Emirati and Iraqi barrels, run by mainstream companies that have simply adopted the shadow fleet’s habit of going invisible, because invisible feels safer when the water is mined.

And the ships that are moving are moving under guard. The recovery leans on the United States Navy escorting traffic through, which is a quieter fact than it sounds. Economists call the effect moral hazard: when someone else absorbs the downside of a risk, you take more of it than you otherwise would. Tankers are transiting not because the strait is safe but because the Navy is standing between them and the consequence of it not being safe. Pull the escorts, and the calculation changes overnight. The traffic count is not measuring how safe the water is. It is measuring how much cover the world’s most powerful navy is willing to provide, for now.

The question this leaves

So the disagreement resolves into something sharper than a mood. The oil price measures intent, and on intent it is right: both sides want out. The insurers, the freight desks, the ships going dark and the Navy shepherding them measure execution, and on execution the verdict is not in, because mines are still in the water and a commander with a radio is still writing his own rules.

Two markets are looking at the same strait. One is pricing the deal. The other is pricing the distance between the deal and the water. That distance has a price, quoted every day, in a market older than either government. That is the last part of this story.
