Six Months Into the Blockade, Both Sides Were Wrong and Neither One Has an Exit

Iran closed the Strait of Hormuz expecting a global economic crisis. It did not come. Washington answered with a blockade expecting Tehran to fold. It did not fold. Crude sits below $100 and nobody has a way out.

Key Points

Six months ago Iran shut the Strait of Hormuz, bottling up roughly one-fifth of the world’s crude oil supply, on the theory it would force an end to the war on its terms.
It did not trigger a worldwide economic crisis. Crude has oscillated between $80 and $90 a barrel and closed Friday at $91.48 — still below $100.
Washington’s blockade of Iranian ports, imposed in April and reimposed in July after a reopening agreement collapsed, has not changed Iran’s behavior or sparked a popular uprising.
Vali Nasr of Johns Hopkins, a former State Department official: ‘The assumptions of both sides have not come true, and both of them also do not have an exit.’
Prediction markets currently imply about 6% odds that Kharg Island leaves Iranian control by year-end and about 14% odds of a U.S. invasion before 2027 — the crowd is pricing a grind, not a resolution.

The U.S. ability to maintain the naval blockade for many more months is described as uncertain. So is Iran’s ability to sustain the closure.

In one line: Two governments each made a confident forecast about the other and both were wrong — which is the ordinary condition of forecasting, at national scale.

Six months ago Iran closed the Strait of Hormuz and bottled up about a fifth of the world’s crude oil supply. The reasoning was straightforward: choke the artery, trigger a global economic crisis, force Washington to end the war on Iranian terms. It was a confident forecast made by serious people with far better information than any of us have. It was wrong. The crisis did not arrive, crude has spent most of the period oscillating between $80 and $90 a barrel, and President Trump was not forced to end anything.

So Washington made its own confident forecast. A naval blockade of Iranian ports, imposed in April, lifted briefly under a memorandum on reopening the waterway, then reimposed in July when that collapsed. The theory: economic pressure changes behavior. Six months on, it has not changed Iran’s behavior, has not produced a popular uprising against the Islamic Republic, and has not reopened the strait to free navigation.

The quote worth keeping

Vali Nasr, a professor of Middle East studies at Johns Hopkins and a former State Department official involved in informal contacts with Iran, gave the Journal the line that sums it up: ‘The assumptions of both sides have not come true, and both of them also do not have an exit.’ Iran’s leverage over the strait is slowly eroding under the U.S. military campaign — one energy analyst quoted in the piece observes that the Iranians simply are not able to shut it all down. But Tehran retains ways of escalating a protracted conflict, and the American ability to hold a naval blockade for many more months is described as uncertain.

The prediction markets are pricing exactly that stalemate. As of this weekend they imply roughly 6% odds that Kharg Island — Iran’s main oil export terminal — leaves Iranian control by the end of the year, and about 14% odds that the United States invades before 2027. Read those two numbers together and the crowd is not betting on escalation or resolution. It is betting on a grind.

Why an unresolved conflict is a different problem

A resolved conflict, in either direction, is something a portfolio can absorb. Prices reset and life continues. An unresolved one is harder, because it keeps a premium in the system indefinitely without ever telling you how long. That is precisely what is showing up in American fuel prices: diesel set an all-time record this week at $5.85 a gallon while crude sits at $91, because the constraint has moved from the barrel to the refining and shipping of it. The disruption is not in the commodity everyone watches. It is downstream of it.

For a household, none of this is actionable as a trade, and it should not be treated as one. It is actionable as a budgeting fact. Fuel, freight and anything that moves on a truck carry a cost that is now six months old and shows no scheduled expiry. When people ask whether they should do something about the Middle East in their 401(k), the honest answer is almost always no — but the honest answer about the household cash-flow statement is frequently yes.

The wider lesson is the one both capitals just learned in public. Two governments with satellite intelligence and career analysts each made a confident forecast about the other and both were wrong. It is worth remembering that the next time a plan depends on knowing what happens next. Plans that survive are built to work across several outcomes, not to be right about one. Bring the statement and we will look at which kind yours is.

What It Means For Your Portfolio

Hold — the energy exposure is a margin fact, not a forecast

An unresolved conflict is harder to own than a resolved one, because it keeps a premium in prices with no expiry date attached. Six months in, the constraint has migrated from crude, which is priced at $91, to refined fuel, which set a record this week. That distinction is where the actual economics live.

General planning principles, not advice for anyone in particular: geopolitics almost never justifies changing a retirement allocation, and almost always justifies revisiting a household budget. Fuel and freight costs feed into groceries, deliveries and anything trucked, and a cash-flow plan built on last year’s numbers is quietly out of date.

The book’s energy exposure is held rather than added to here. The reasoning is deliberate: the refining spread is a war premium, and war premiums end — on a date nobody controls. Position sizes reflect that the thesis has a genuine bear case, which is why the weights are modest rather than expressive.
