The toll of a chokepoint

The Hill reports that Vice President Vance has described "some progress" in negotiations between Iran and Oman over the Strait of Hormuz — the critical waterway that has become, in his words, "a key sticking point" in broader talks. One welcomes any progress. But the phrase "hangs in balance" should concentrate minds, because what hangs with it is not merely a diplomatic headline but a measurable charge levied on every economy that depends on energy moving by sea — which is to say, nearly all of them.

I was not present at the birth of global petroleum markets, nor can I speak to the precise engineering of modern oil futures or the mechanics by which a Hormuz disruption ripples through supply chains I never lived to see. What I can say, with some confidence earned at Bretton Woods, is that international commerce does not sustain itself by accident. It rests on architecture — on treaties, on agreed passages, on the implicit guarantee that goods contracted today will arrive tomorrow. When that architecture is placed in jeopardy, the uncertainty alone is enough to suppress investment and push up costs, long before a single tanker is actually turned back.

This is the point that short-run negotiators so reliably miss: the cost of a bad or incomplete settlement is not paid at the signing table. It is paid in the elevated oil price embedded in every flight ticket, every manufactured good, every heated home across importing nations — and it is paid most heavily by those least able to absorb it. I argued, after Versailles, that a punitive settlement whose economic logic was never honestly examined would generate consequences its architects could not foresee. I do not say the Iran situation is Versailles; that would be a false analogy. I say only that the habit of mind is the same: reach a political agreement, declare victory, and leave the macroeconomic arithmetic to sort itself out. It never does.

The animal spirits problem compounds this. Investment decisions in energy infrastructure, in shipping, in refining capacity — all of these require a horizon of reasonable confidence. A Strait that "hangs in balance" is a Strait that cannot anchor long-term capital commitments. The uncertainty premium is real and it is costly, even if it never shows up in the headline diplomatic dispatch. Keynes's insight — that confidence is not a luxury decoration on the economy but a structural input to it — applies here as plainly as it does to any domestic slump.

What, then, is the policy that is actually buildable? The Oman channel is precisely the kind of multilateral mediation that international architecture was designed to provide: a third party with credibility, a defined process, and a stake in the outcome. That it is happening at all is encouraging (this is inference on my part, not direct knowledge of the talks' substance). The imperative is to ensure that any agreement reached is durable — underwritten by enough parties, with enough economic interdependence at stake, that the temptation to reopen it at the next moment of domestic political pressure is genuinely costly to resist. A settlement that is politically convenient today but economically fragile tomorrow is not a settlement; it is a deferred disruption. The world's traders, its workers, and its consumers deserve better accounting than that.
