From the International Monetary Fund's IMFblog, June 11:
The US dollar continues to cede ground to nontraditional currencies in
global foreign exchange reserves, but it remains the preeminent reserve
currency
Dollar dominance—the outsized role of the US dollar in the world economy—has been brought into focus recently as the robustness of the US economy, tighter monetary policy and heightened geopolitical risk have contributed to a higher greenback valuation. At the same time, economic fragmentation and the potential reorganization of global economic and financial activity into separate, nonoverlapping blocs could encourage some countries to use and hold other international and reserve currencies.
Recent data from the IMF’s Currency Composition of Official Foreign Exchange Reserves (COFER) point to an ongoing gradual decline in the dollar’s share of allocated foreign reserves of central banks and governments. Strikingly, the reduced role of the US dollar over the last two decades has not been matched by increases in the shares of the other “big four” currencies—the euro, yen, and pound. Rather, it has been accompanied by a rise in the share of what we have called nontraditional reserve currencies, including the Australian dollar, Canadian dollar, Chinese renminbi, South Korean won, Singaporean dollar, and the Nordic currencies. The most recent data extend this trend, which we had pointed out in an earlier IMF paper and blog.
These nontraditional reserve currencies are attractive to reserve managers because they provide diversification and relatively attractive yields, and because they have become increasingly easy to buy, sell and hold with the development of new digital financial technologies (such as automatic market-making and automated liquidity management systems).
This recent trend is all the more striking given the dollar’s strength, which indicates that private investors have moved into dollar-denominated assets. Or so it would appear from the change in relative prices. At the same time, this observation is a reminder that exchange rate fluctuations can have an independent impact on the currency composition of central bank reserve portfolios. Changes in the relative values of different government securities, reflecting movements in interest rates, can similarly have an impact, although this effect will tend to be smaller, insofar as major currency bond yields generally move together. In any event, these valuation effects only reinforce the overall trend. Taking a longer view, over the last two decades, the fact that the value of the US dollar has been broadly unchanged, while the US dollar’s share of global reserves has declined, indicates that central banks have indeed been shifting gradually away from the dollar.
At the same time, statistical tests do not indicate an accelerating decline in the dollar’s reserve share, contrary to claims that US financial sanctions have accelerated movement away from the greenback. To be sure, it is possible, as some have argued, that the same countries that are seeking to move away from holding dollars for geopolitical reasons do not report information on the composition of their reserve portfolios to COFER. Note, however, that the 149 reporting economies make up as much as 93 percent of global FX reserves. In other words, non-reporters are only a very small share of global reserves.
One nontraditional reserve currency gaining market share is the Chinese renminbi, whose gains match a quarter of the decline in the dollar’s share. The Chinese government has been advancing policies on multiple fronts to promote renminbi internationalization, including the development of a cross-border payment system, the extension of swap lines, and piloting a central bank digital currency....
