Nontraditional Reserve Currencies on the Rise

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.
