Will the U.S. Dollar Be Dethroned? (2024)

There has been speculation lately that the U.S. dollar is on the verge of a major decline and might even lose its status as the world's major reserve currency. "De-dollarization," or the movement away from using the U.S. dollar as the primary currency of exchange in global trade and investment, has become a hot topic in financial publications. It appears to stem from news that China is beginning to use the yuan in commodity trades with a handful of trading partners, and Brazil and Argentina are exploring the potential for a common currency. Extrapolating these trends, the argument is that demand for dollars will fall, sending its value steeply lower.

Our view is that this argument is overblown. A long-term trend toward diversification of currencies in global financial transactions and trade may develop, but it's a big leap from dollar dominance to de-dollarization.

While the dollar has declined over the past six months, it remains close to a 10-year high versus currencies of countries with which the U.S. trades. It also remains the primary currency used for trade and financial transactions in the global economy. The size of the recent non-dollar transactions that have raised alarm are very small. Trade in yuan accounted for less than 2% of global trade in 2022.

There are few signs that major foreign holders are poised to suddenly shift away from U.S. dollars and there are few other currencies that could take its place as a reserve currency. In our view, a gradual move to a global economy with a less-dominant dollar is possible over time, but we don't see the dollar losing its reserve currency status.

There are several ways to measure changes in the level of the dollar. We generally look at indices that compare the dollar's value to the values of a broad range of currencies, weighted according to the value of their trade with the U.S. By most measures the dollar has fallen by about 8% to 10% in both real and nominal terms since late last year.

As you can see in the chart below, during the past decade, the dollar has been propelled higher by relatively high U.S. interest rates compared to other major countries, strong capital inflows, and its status as a safe haven in times of turmoil. Its value increased by 1.4 times from its 2011 low to its peak in 2022 in real terms (that is, adjusted for inflation).

A reserve currency needs to be freely convertible and have deep and liquid bond markets to be considered safe for foreign central banks to hold. Central banks need to know that their money is easily and readily available when needed, particularly in times of stress. The U.S., with a large, open, and liquid market for Treasury securities, fits that role. That's why when the COVID crisis hit the global economy, the U.S. Federal Reserve expanded its swap lines with foreign central banks to enable access to dollars for countries that were struggling to access dollars for trade and debt payments.

While other major countries' markets have these qualities, the size and openness of the U.S. market is difficult to match. Europe's bond markets are more fragmented than the U.S. market although a movement toward euro-denominated sovereign debt issuance would provide a stronger base for it as an attractive alternative. Japan's bond market is closely controlled by its central bank, which owns the bulk of its government debt. China has capital controls, and its currency isn't even freely convertible. Giving up capital controls would mean that the government would relinquish control over investment flows and leave the currency susceptible to decline if domestic investors moved their money elsewhere.

Over the next six to 12 months, we see room for a moderate cyclical decline in the dollar. The main driver is likely to be a greater convergence of interest rates in the major economies as the U.S. Federal Reserve nears the end of its rate hiking cycle while other central banks continue to tighten policy. The European Central Bank and Bank of England appear on track to keep hiking rates due to persistently high inflation. The Bank of Japan may loosen its yield curve control policy, allowing bond yields to move up, which would likely mean less demand for U.S. dollar-denominated assets by Japanese investors. We view these developments as the most significant risk to the dollar's strength in 2023 and 2024.

Longer-term, movement to a multi-currency global economy is possible and could have benefits, particularly for emerging-market countries where moves in the dollar can have big effects on economic growth. However, it would require some major structural changes in many regions—such as reducing barriers to trade and investment, along with strengthening protections for investors. These changes take time and political will.

Although we don't see a major bear market in the dollar developing soon, we do believe that investors can benefit over the long run from global diversification. Diversification works best when economic cycles diverge, which may happen later this year if U.S. economic growth slows relative to expansions in other countries. With U.S. interest rates likely to peak in the next few months, returns in global bond markets may improve. The current yield on the Bloomberg Global Aggregate ex-USD index is 2.8%, compared to the Bloomberg US Aggregate Bond Index yield of 4.4%. That yield gap still favors U.S. bond investments, but it is narrow enough to be offset by a modest drop in the dollar.

Overall, a further easing in the dollar's strength over the course of 2023 could be an opportunity for investors to diversify globally, but we don't see it portending a major structural change in the world currency order.
