The American strategy in Iran was meant to be simple: apply pressure, choke the regime, force concessions, reopen the Strait of Hormuz, and then declare victory before the bill arrived. The bill has arrived. Brent crude has surged above $126 a barrel, reaching a wartime record, after reports that Donald Trump is to be briefed on new military options against Iran. The market has understood what Washington still refuses to say plainly: the war has not been contained, the blockade has not solved the crisis, and the illusion of controlled escalation is collapsing. The Strait of Hormuz remains effectively closed. The United States blocks Iranian-linked vessels. Iran blocks almost everyone else. What was presented as leverage has become paralysis. One-fifth of the world’s oil and LNG flows have been trapped inside a geopolitical experiment designed by people who confused coercion with strategy.

The result is painfully clear. Energy prices are rising, inflation risks are returning, shipping routes are broken, and the world economy is being asked to finance a policy that has failed to deliver either peace or passage. Trump now insists that the blockade is “more effective than bombing”. Perhaps. But effective at what? It has not forced Iran to accept a nuclear deal. It has not reopened Hormuz. It has not reassured allies. It has not protected consumers. It has instead created a perfect machine for global stagflation: higher energy prices, lower confidence, weaker growth and rising political anger.

The proposed next step, short, powerful strikes against Iranian infrastructure, is even more dangerous. It suggests that Washington is trying to escape the failure of pressure by adding more pressure, as if the first dose had not already poisoned the system. Hypersonic missiles, seized tankers, and threats of renewed attacks may impress television audiences. They do not reopen maritime corridors. They do not rebuild trust. They do not make insurers comfortable, crews willing, or traders calm.

For the rest of the world, the danger is immediate. Asia faces the sharpest shock, as the largest importer of Gulf energy. Europe faces renewed inflation just as growth stalls. Emerging markets face weaker currencies, higher import bills and tighter monetary conditions. Food prices may rise due to fertiliser shortages. Airlines are cutting capacity. Petrochemical producers are reducing output. The oil shock is no longer an abstract market movement; it is now affecting transport, agriculture, manufacturing, and household budgets. The United States may believe it can absorb the shock better than others because it produces oil. That is only half true. America may export more crude, but American consumers still buy petrol, American companies still use diesel and jet fuel, and American bond markets still react to inflation. A prolonged energy shock would make Fed policy even more difficult, forcing rates to stay higher for longer precisely when growth begins to weaken.

This is the strategic irony. By trying to break Iran economically, Washington risks exporting inflation to its allies, instability to emerging markets and recession risk to itself. Iran, meanwhile, does not need to win conventionally. It only needs to keep Hormuz uncertain. A few gunboats, a few threats, a few delayed transits, and the global economy does the rest. This is asymmetric warfare at its most efficient: small instruments, enormous consequences. The failure of the US strategy is not that it lacked force. It is that it mistook force for an end-state. It is assumed that pressure will automatically lead to capitulation. Instead, pressure has produced resistance, maritime chaos, and an increasingly hostage world economy. The next escalation may still come. The military options are being prepared. The rhetoric is hardening. The oil market is already voting. But the real lesson is already visible: a blockade that cannot reopen Hormuz is not a solution. It is merely another form of closure. And the longer it lasts, the more the rest of the world will pay for Washington’s inability to distinguish strategy from spectacle.
