The debate over the dollar’s future has settled into two familiar camps. One side predicts an accelerating collapse as BRICS nations and sanctioned economies build alternatives to the US-dominated financial system. The other insists the currency is simply too deeply embedded in global trade and finance to be displaced, regardless of political turbulence. Both positions share the same weakness: they treat the question as if it has no historical precedent. It does. Sterling’s long, punctuated, institutionally managed decline from global dominance offers the most instructive available template — and it is not particularly reassuring for the dollar’s long-term defenders.
Britain accounted for roughly 30 percent of global trade in the latter half of the nineteenth century, and approximately 60 percent of world trade was invoiced and settled in sterling at the peak of that era. By any reasonable measure, Britain’s hard power peaked somewhere between the Napoleonic and Boer Wars. Yet sterling was not definitively surpassed by the dollar until the immediate postwar years, and retained a meaningful global role well into the 1970s. From peak dominance to genuine displacement took approximately a century. The decline was not smooth or gradual. It was punctuated by crises of global consequence — the collapse of the gold standard in 1931, a forced reset of the Bretton Woods monetary system in 1949, and the complete unraveling of Bretton Woods in 1968, followed by the IMF bailout of Britain itself in 1976.
The “No Alternative” Argument Has Been Made Before
The most common defense of dollar permanence — that no viable alternative exists — rests on an assumption that sterling’s history directly contradicts. Sterling was not displaced by a single superior successor. Throughout its nineteenth-century dominance, it faced serious rivals in the French franc and German mark. In the interwar years, the dollar and sterling were close competitors rather than clear incumbent and challenger. Dominance has never required the absence of alternatives. It has required that a currency serve as the unit of account for the world’s safest and most liquid assets — and safety arises through scale and credibility, not through any inherent structural barrier to competition.
The euro already accounts for a larger share of global trade invoicing than the dollar when measured on a pure transaction basis, largely reflecting the scale of intra-Eurozone commerce. It holds a stable 20 percent share of global foreign exchange reserves, even as the dollar’s share has fallen from nearly 75 percent to below 60 percent over the past quarter-century. China and the Eurozone are larger trading partners than the United States for the majority of the world’s economies. Neither the euro nor the renminbi needs to replicate the dollar’s full institutional depth to claim a significantly larger share of a multipolar reserve system.
The Signals Already Visible
The dollar’s behavior during the two most geopolitically significant stress events of the past year — the “Liberation Day” tariff announcement and the Greenland sovereignty dispute — produced a pattern that surprised many financial analysts. In both episodes, US equities fell, bond yields rose, and the dollar depreciated simultaneously. That combination — normally associated with emerging market stress events rather than with the world’s reserve currency — bears the hallmarks of an asset under structural rather than cyclical pressure.
The dollar’s strengthening following the attack on Iran reflects the United States’ position as a major energy exporter — a relatively mechanical response to oil price dynamics rather than evidence of enduring reserve status. A currency that rises when energy prices spike because the US sells oil is not demonstrating the same kind of safe-haven demand that caused capital to flow into dollar assets during the 2008 financial crisis or the early months of the COVID-19 pandemic.
Sterling’s century of managed decline was sustained by one structural reality above all others: the vast accumulation of sterling balances during and after the war meant that rapid liquidation would have destroyed asset values globally, making it in no one’s immediate interest to accelerate the transition. The same logic applies to dollar assets today — trillions of dollars in US Treasury holdings distributed across sovereign wealth funds, central bank reserves, and private institutional portfolios make a sudden exit structurally catastrophic for the holders themselves. The dollar will not fall quickly. But sterling did not fall quickly either, and by 2001 a pound that had once bought nearly five dollars could no longer buy two. The forces are structural, the direction is visible, and the timeline, measured in decades rather than months, should offer cold comfort to those who mistake slowness for permanence.
