How much longer can the United States rely on the US dollar to dominate the global financial system, and what happens when the cracks finally start to show? In this week's Debunking Economics podcast, Phil Dobbie and Professor Steve Keen travel back to the 1944 Bretton Woods conference to revisit John Maynard Keynes's ultimate lost argument. Steve details how Keynes's visionary proposal for a global clearing union and an international currency—the Bancor—was explicitly designed to penalise both hoarding surplus nations and debt-ridden deficit nations, spreading wealth to developing countries and preventing destructive "beggar-thy-neighbour" tariff wars. By rejecting Keynes's framework in favour of institutionalised US dollar hegemony, the modern global economy has instead trapped itself in a cycle of systemic trade imbalances and ballooning private debt. Tune in to explore why today's aggressive tariff landscapes are exposing the structural fragility of the greenback, whether Alternative Modern Monetary Theory (MMT) baseline assumptions are entirely wrong about trade, and what a chaotic shift away from the world's primary reserve currency means for global stability.
