    The road to dollar dominance

    The title of world’s dominant currency isn’t like a grand slam trophy or a world wrestling title: it doesn’t change hands that often. It usually changes hands once every few centuries, and even then there’s a bit of overlap where waning and nascent currencies coexist as dominant forces. In seventeenth century Europe, the Netherlands was dominant, partly thanks to innovation of silver-coin-backed bank notes – florin – circulating alongside actual coins –guilder. The sixteenth century was all about Spanish pieces of eight, while the British pound sterling was unshakeable between the Napoleonic Wars to the start of WWI. By this metric, the current dominant currency, the USD, is in late middle age.

    How did the USD come to dominate? A breathtaking postwar run. At Bretton Woods, New Hampshire, in 1944, world leaders created a post-war system of fixed exchange rates, where currencies were pegged to specific values rather than floating freely in markets. The system placed the strong USD at its centre and obliged other countries to fix their exchange rates to the dollar, giving the USD extraordinary privilege as the global anchor currency. In 1950, the US economy accounted for a wildly high 36 percent of global GDP – a staggering concentration of economic power.

    Today, the USD is the lingua franca of global trade markets. And as the world has globalized, the impact of what it means to be the dominant currency has grown ever more outsized. No-one in Japan cared much about Dutch florins in the seventeenth century, but the Japanese are extremely interested in how the USD performs in the present day.

    Network effects ensure international currency usage becomes a monopoly: it would be chaotic to use all 150+ world currencies, so many naturally fall by the wayside. About 90 percent of international currency transactions involve USD on one side or another because it’s simply cheaper to use the dollar as a vehicle currency – rather than converting yen to euros directly, banks route through dollars for better liquidity and lower costs. Almost 60 percent of foreign exchange reserves – the stockpiles of currencies that central banks hold for international transactions and crisis management – are held in USD. International goods and assets are often priced in USD, with roughly 80 percent of oil priced in dollars.
