Glob­al­i­sa­tion

The men who rebuilt the world economy after 1945 were haunted by what had just happened. They had watched the 1930s slide from economic nationalism into autarky into war, and they drew a sharp lesson: openness left to the mercy of national politics would tear itself apart again unless it was held together by rules. The order they designed was globalisation with a seatbelt — deliberately managed, deliberately partial.

The blueprint was drawn largely at Bretton Woods in 1944, where delegates from forty-four nations agreed a system of fixed but adjustable exchange rates anchored to the dollar, and created the International Monetary Fund and what became the World Bank to backstop it. Trade was handled separately, through the General Agreement on Tariffs and Trade signed in 1947, which brought tariffs down in successive negotiating rounds over the following decades. The whole architecture was designed to let goods flow more freely while giving governments room to protect employment at home — an arrangement one scholar later called embedded liberalism.

The third wave, from the 1980s onward, went further and faster than anything before it, and it is the one we actually lived through. Two forces drove it. One was political: the fall of the Berlin Wall in 1989, the opening of China's economy under Deng Xiaoping, and India's reforms in 1991 brought billions of people who had sat outside the trading system suddenly inside it. The club became something much closer to the whole world. The other force was technological and, oddly, very physical.

That force was the shipping container — a plain steel box, standardised in the 1960s, that turned out to matter more than almost any policy. Before it, loading a ship was slow, expensive manual labour that could eat a large share of a cargo's value. Afterwards, cranes moved sealed boxes between ship, train and truck in minutes, and the cost of moving goods across the world fell to something close to trivial. Combined with cheap communications, this made it viable to break production apart and scatter it — design in California, components in Korea, assembly in China — into what we now call global supply chains.

Step back from the four waves and a pattern comes into focus that cuts against how we usually think. We tend to treat globalisation as a natural law, a one-way ratchet of technology forever tightening the world — as if openness were simply the default state that history keeps returning to once the interruptions clear. The record says otherwise. Integration has advanced when a dominant power and a reigning set of ideas made openness pay, and it has retreated when the politics turned. It is not weather. It is a choice, made and unmade.

That reframing matters because it changes how we read the present. The evidence for a fourth turn is now hard to dismiss. Trade as a share of the world economy stopped rising after the 2008 financial crisis and has drifted sideways since — the long climb simply stalled. The pandemic taught governments that lean, globe-spanning supply chains were also brittle ones, and the words reshoring, friend-shoring and economic security migrated from think tanks into official policy. Tariffs, once the villain of the 1930s story, are back as a mainstream instrument, wielded now by the country that spent seventy years championing openness.

Keynes's Londoner of 1913 believed his interconnected world was permanent, ordinary, unremarkable — the settled condition of a civilised age. Within five years it lay in pieces, and it took most of the century to rebuild something comparable. The lesson embedded in that vanished summer is not that openness is fragile in some sentimental sense, but that it has always rested on foundations that are political before they are technological. Ships and cables and steel boxes lowered the cost of connection; they never guaranteed that anyone would choose to stay connected.
