The Strait of Hormuz and the Cost of Concentration

The Strait of Hormuz is the narrow exit from the Gulf to the open sea, and an outsized share of the world’s energy leaves through it. For most of the year it is invisible — a line on a chart that goods pass without comment. The weeks when it stops being invisible are the ones that matter, because the strait does not have to close to make itself felt.

A rise in tension is enough. War-risk cover is repriced, some owners slow down or wait for clarity, a few reroute the long way round, and vessel capacity tightens across the region. None of that requires a single ship to be turned back — and very little of it stays confined to oil.

The cost travels through channels that have nothing to do with the cargo in question. Insurance is the fastest: a higher war-risk premium lands on every hull in the area within days. Routing is next — diverting around the Cape of Good Hope adds weeks of sailing, which pulls ships out of rotation, tightens space on the lanes that remain, and lifts rates well beyond the Gulf.

That is the uncomfortable feature of a chokepoint. Freight, fuel and insurance are priced globally, so a firm inherits the disruption whether or not its own goods ever touch the strait. The exposure is not a line on a map; it is in the rate card.

The real subject, then, is not Hormuz. It is concentration. Any network that rests on a single passage — or a single route, a single supplier, a single origin for a category — inherits that point’s worst day. The strait is simply the most visible version of a rule that applies everywhere goods move.

What answers it is optionality held in advance: more than one origin for the categories that can bear it, buffer inventory positioned ahead of the crossings that matter, and routings mapped before they are needed rather than during the scramble. FMC’s footprint — 31 facilities across 26 markets — is organised around keeping more than one path open into each market, not around finding the single cheapest one and hoping it stays clear. Optionality is not free; it trades a little efficiency in calm weeks for room to move in the hard ones.

Narrow water is a permanent feature of the map, not a passing crisis. There will always be a strait, a canal or a pass that concentrates a disproportionate share of the world’s trade into a few miles. The firms that come through those weeks intact are the ones that priced the risk in before it arrived — not the ones that discovered it in the rate card.

The map has always had its narrow places; the advantage lies in never depending on a single one.
