3 reasons we don't see a credible threat to U.S. dollar leadership

U.S. economic growth has proved resilient over the past five years, while overseas growth has lagged. Robust domestic expansion and elevated interest rates have pushed the U.S. dollar index above its 20-year average,* although trade policy uncertainty has recently weighed on the currency’s momentum.

There have also been headlines around the BRIC (Brazil, Russia, India, China) economies seeking to create a competing currency and calling for de-dollarization, particularly in oil and commodity trading. While headlines like these emerge every so often, we continue to see the U.S. dollar maintaining its role as the preeminent reserve currency to the world.

Some marginal declines in dollar trade could occur. But an outright demise of the dollar does not seem credible for three key reasons:

1. The U.S. dollar still accounts for the majority of global reserves.

The U.S. dollar dominates foreign exchange reserves, which are assets held by global central banks in foreign currencies. These reserves are often used for trade payments or to support a currency if needed.

The percentage of reserves held in U.S. dollars has moderated over the past few decades, as the U.S. economy accounts for a somewhat smaller share of global activity. However, the dollar remains the most held currency by far, comprising nearly 60% of global reserves. The euro, which is the next largest currency held in reserves, makes up about 20% of reserves.

The remaining currency reserves are relatively small in comparison. For example, the Chinese renminbi makes up only 2.2% of global reserves as of 2024.

2. Global trade, including oil trade, is still largely conducted in dollars.

The Federal Reserve estimates that between 1999 and 2019, the dollar accounted for 96% of trades in North America, 74% in the Asia-Pacific region, and 79% for the rest of the world. The only region where trade was not dominated by the U.S. dollar was Europe, where the euro remained the preferred trade currency.

In addition, global oil trade, which accounts for about 10% of overall trade, is still largely conducted in U.S. dollars. While the dollar may become less of a force here, this sector remains a relatively small part of overall trade and may still use the U.S. dollar in some transactions.

3. The U.S. dollar is backed by deep, liquid and regulated financial markets.

Perhaps a key reason the U.S. dollar has been the dominant currency globally is the strength and stability of the U.S. economy, as well as the deep and liquid financial markets the U.S. offers.

The U.S. has by far the largest bond and stock markets globally. Importantly, the financial markets are highly regulated and offer borrowers and lenders access to a large set of counterparties. Overall, the U.S. is still the world’s largest economy with the deepest capital markets.

There are no realistic alternatives to replace the dollar anytime soon. The euro has faced political risk in the past, and the renminbi has significant capital flow restrictions from the Chinese government.

These factors have allowed the U.S. dollar to maintain its dominant position in international trade and finance. In our view, the dollar will continue to do so for the foreseeable future.

The bottom line

While headlines around the U.S. dollar may raise questions or concerns for investors, we continue to see no credible threat to its leadership position globally. The dollar’s value may fluctuate relative to other currencies, driven by factors such as central bank interest rate policy, inflation regime and economic growth. But these are within the norm of financial market volatility.

During times of turbulence, such as with the pandemic or more recent inflation concerns, we have seen investors move foreign currency into the U.S. dollar as a flight to safety. This points to continued investor confidence in the stability of the dollar into the future.

Action for investors

We would not recommend any portfolio shifts based on fears around the U.S. dollar. But we continue to recommend investors consider diversifying their portfolios with exposure to markets and currencies outside the U.S. This includes international equities and bonds, and sectors with global exposure such as industrials and energy. All of these could provide diversification to U.S. dollar exposure.

Historically, international equities tend to perform well when the dollar is weaker against other currencies. Conversely, U.S. investments typically outperform when the dollar is stronger, as the chart below illustrates.

The rise in the dollar over the past decade has weighed on international returns, but this year’s trade disruptions and new fiscal stimulus abroad have acted as catalysts for improved relative returns. Therefore, an appropriate international allocation is likely to benefit from any dollar softness, which could occur as U.S. inflation approaches the Fed’s 2% target or global growth rebounds.

In the first half of 2025, international equities (as measured by the MSCI World ex USA Index) delivered a total return of 20%, compared with just 6% for the S&P 500. Despite this strong performance, they continue to trade at a substantial discount to U.S. equities. This valuation gap suggests global indexes may have room to perform well going forward, especially if further softening of the U.S. dollar provides additional support.
