For roughly five hundred years, the global trading system has been underwritten by Western naval power. By David Hilton at XYZ.

The Portuguese opened the ocean routes in the fifteenth century. The Dutch and the British turned those routes into commercial highways. In the twentieth century, the United States Navy inherited the task of keeping the oceans open.

Global capitalism was never simply a matter of markets and finance. It was also a matter of security.

Merchants will ship goods across oceans only if they believe those goods will arrive safely. That belief depends on naval patrols, international law, and an intricate web of maritime insurance markets centred historically in London.

Trade, in other words, requires both protection and trust. For centuries, the Western maritime powers provided both. …

Periods of open maritime trade have been the exception, not the rule:

Since World War II at least, the Western world has lived inside the illusion that global integration is permanent. Goods flow effortlessly across oceans. Supply chains stretch thousands of kilometres without serious interruption. Distance itself seems to have been conquered.

Cheap energy and secure sea lanes created that illusion.

Yet history offers a more sobering perspective. Large trade networks have collapsed before. The Bronze Age trading system disintegrated around 1200 BC. The Roman Mediterranean fractured in late antiquity. The Silk Road periodically vanished for centuries when political and military conditions made long-distance commerce too dangerous. …

Iran’s attacks on Gulf oil infrastructure and its effective closure of Hormuz represent more than a regional escalation. They mark a signal event in the slow unravelling of the economic order that has shaped the modern world.

Collapse is slow at first:

The consequences will not appear overnight. Civilisational systems rarely collapse in a single dramatic moment. Instead, they begin to strain. Prices rise. Supply chains falter. Governments scramble to stabilise markets that were once taken for granted. …

For the past half century, the industrial world has lived within a system built on cheap energy, secure sea lanes, and a financial architecture tied closely to the global oil trade. That system produced extraordinary prosperity, but it also created an illusion of permanence.

Now the foundations are beginning to crack.

Modern civilisation likes to imagine that its problems are primarily political or technological. Yet the deeper structures of history are often logistical. Empires rise when they master the movement of energy and goods across distance. They falter when those flows become uncertain.

The tankers burning in the Persian Gulf are therefore more than images of regional conflict. They’re a planetary blood clot blocking the most important coronal artery of our civilisation.
