The ledger nobody is reading at the table

The Hill reports that Iran has shared a seven-day plan with the United States to end the present hostilities, reopen the Strait of Hormuz, and restart some form of diplomatic engagement. I do not know the precise terms — I was not present at those conversations, and I lived long before this confrontation took its current shape — but the structure of the problem is one I recognise in my bones. It is the structure of every negotiation in which short-run political imperatives pull both parties away from the long-run arithmetic that will judge them.

The Strait of Hormuz is not merely a navigational question. It is, by most credible reckoning (and here I defer to the engineering details of modern energy markets, which are beyond my direct knowledge), among the most consequential chokepoints in the world's oil supply chain. When it is closed or credibly threatened, the cost does not fall neatly on the parties to the dispute. It diffuses outward — into the energy bills of households in countries that have no vote in the matter, into the input costs of manufacturers already operating on thin margins, into the confidence of investors who cannot price a war premium with any precision. This is the very nature of a disruption to international trade: the innocent bystander absorbs the externality.

I have written before — in another context, another century — about the economic consequences of political settlements made in haste or in anger. The lesson of Versailles was not that one must be lenient with adversaries; it was that a settlement whose terms cannot be met will not, in fact, be met, and that the resulting instability costs more than the original grievance was ever worth. I offer no opinion on the justice of the present quarrel between the United States and Iran, which involves questions of military security and political legitimacy that are not mine to adjudicate. What I will say is this: a seven-day plan, if it is genuine, is at minimum a recognition by one party that the cost of closure is unsustainable. That recognition is the beginning of rational negotiation, not the end of it.

The macroeconomic danger here is a familiar one. An energy price shock of sufficient magnitude and duration is a supply-side contraction that no central bank can easily offset and no fiscal authority can fully replace. It raises costs across the productive economy, compresses real incomes, and — crucially — it depresses the animal spirits of investors at precisely the moment when sustained private investment is most needed. Uncertainty, I have always argued, is not a neutral condition. It is itself a drag. When the chief executive of any enterprise cannot price their energy inputs six months forward, they do not invest; they wait. And when enough of them wait, the aggregate consequence is a slowdown that feels inevitable but was, in truth, a choice made in a negotiating room.

The right policy inference — and here I speak from disposition, not from knowledge of the specific terms on the table — is that the reopening of the Strait should be treated as a matter of international economic architecture, not merely bilateral diplomacy. The costs of its closure are collective; the institutions best placed to guarantee its openness should therefore be collective. Whether the 2026 institutional landscape can support such a framework, I genuinely do not know; the multilateral machinery built at Bretton Woods has evolved in ways I can only infer. But the principle holds: when the externalities of a bilateral dispute are global, the solution architecture must reach beyond the two parties at the table. The alternative — leaving the world's energy supply to the contingencies of a seven-day plan agreed under military pressure — is not a settlement. It is a postponement, and postponements have their own price.
