LONDON, July 8 — The future of the dollar as the world’s primary reserve currency is not in imminent peril, but the foundations of its dominance are being tested by forces that have gathered momentum quietly over the past decade. The salient point from the International Monetary Fund’s 2022 assessment is that the dollar’s share of global reserves could decline further, yet it remains dominant for the foreseeable future.
That judgement still frames the debate as policymakers and central bankers weigh the risks of a gradual erosion versus a sudden collapse. At the centre of this discussion sits the IMF’s Special Drawing Right, or SDR.
This is not a currency in the traditional sense but a supplementary foreign exchange reserve asset, a basket that currently holds the dollar, the euro, the yen, the pound sterling and the renminbi. For all the noise about de-dollarisation, the SDR remains a relatively obscure instrument in global finance. But if the IMF were to expand its role, the SDR could become a more significant player in the international monetary system.
The dollar’s advantages are not trivial. The United States economy remains the world’s largest, with a gross domestic product of $25.5 trillion in 2022.
That scale matters, but it is the depth and liquidity of US financial markets that give the dollar its structural edge. The rule of law and the credibility of American institutions, notably the Federal Reserve’s independence, provide a level of predictability that few alternatives can match. Then there are network effects.
The dollar is dominant not simply because it is the largest economy’s currency, but because it is the currency everyone else uses. That self-reinforcing dynamic — the more people use it, the more useful it becomes — is difficult to dislodge.
Digital challengers
China has been the most explicit in seeking alternatives. Its digital renminbi, the e-CNY, was launched in pilot programmes in 2020. The technology could, in theory, facilitate cross-border payments that bypass the dollar-based clearing system entirely.
That is the ambition, at least. For all the noise about the e-CNY’s potential, its actual adoption beyond China’s borders remains limited.
The renminbi’s share of global reserves, though growing, is still modest. The currency is not fully convertible, and China’s capital account remains tightly controlled. Those are not trivial impediments.
A sudden loss of reserve status for the dollar is unlikely. The more plausible scenario, as the IMF’s work suggests, is a gradual erosion — a slow shift that could accelerate if the US fiscal position weakens materially or if alternative currencies gain sufficient trust from central banks and market participants.
What to watch
The key indicators to track are not dramatic. They are the quarterly reserve composition data from the IMF, the pace of bilateral swap arrangements between central banks, and the development of cross-border payment infrastructure outside the dollar system. None of these alone signals a tipping point. Taken together, they suggest a world in which the dollar’s dominance is no longer taken for granted, even if it remains, for the moment, unassailable.
