LONDON, July 10 — The shift is subtle but seismic. Eighty years after John Maynard Keynes helped design the post-war economic order, his ghost is haunting a very different financial system. The British economist, who died in 1946, led the UK delegation at the 1944 Bretton Woods Conference.
There, he proposed a radical alternative to the dollar-centric system that ultimately prevailed. His idea: a new international currency called the “bancor,” designed specifically for clearing international trade imbalances.
It never saw the light of day. Instead, the US delegation, led by Harry Dexter White, successfully pushed for a system anchored by the US dollar, convertible to gold. That arrangement made the dollar the world’s primary reserve currency.
It’s a structure that still shapes global finance today. Keynes’s loss at Bretton Woods was a defining moment.
His bancor proposal would have created a mechanism for clearing international trade imbalances. The dollar system that replaced it placed the US dollar at the center. What’s changing is the context.
The Bretton Woods system that Keynes helped create, even if not in his preferred form, established the International Monetary Fund and the World Bank. Both institutions remain central to global economic governance. The trend underneath is a quiet intellectual revival.
Keynes’s “General Theory of Employment, Interest and Money,” published in 1936, advocated for government intervention to manage economic cycles. That thinking shaped post-war policy across the West.
Keynes died in 1946, just as the Bretton Woods system began operating. He never saw the dollar hegemony his bancor proposal was designed to avoid. But his core insight endures.
Keynes argued that managing aggregate demand and avoiding deflationary spirals was essential for economic stability. That principle remains embedded in the DNA of the IMF, the World Bank, and the economic policies of most developed nations.
The irony is sharp. The system that defeated Keynes’s bancor proposal is now the system under pressure. The dollar’s role as the world’s primary reserve currency, formalized at Bretton Woods, is being questioned.
The IMF and the World Bank, both born from the same conference, are now grappling with challenges. The institutions he helped create are adapting, slowly, to a world where the US dollar’s supremacy is no longer taken for granted. What to watch next: whether the bancor idea, or something like it, gets a second life.
The concept of a neutral international settlement currency has been revived in various forms. None have gained traction.
But the underlying logic remains compelling: a system that forces both surplus and deficit countries to adjust, rather than placing all the burden on the deficit side. Keynes lost that argument in 1944. The system that won instead — dollar hegemony backed by gold convertibility — lasted barely three decades before the gold link was severed.
The dollar has remained dominant since, but the cracks are visible. The shift is this: the post-war order Keynes helped build, even as a runner-up, is showing its age.
The question is not whether it will change, but what will replace it. And whether the next system will learn from the one Keynes proposed, but never saw implemented.
