Is the U.S. dollar at a turning point? A sharp decline late last year has left many wondering if the greenback’s decade-long bull run is coming to an end.

A continuing downward trend would be welcome news for investors in international bonds and equities, whose total returns have been eroded by currency translation effects. And, in many ways, a correction is overdue. From its trough in 2011 to the recent peak in late 2022, the U.S. dollar rose 45% against J.P. Morgan‘s inflation-adjusted broad-based basket of developed and emerging market currencies. This has left it overvalued against most major and emerging markets (EM) currencies on a purchasing power parity (PPP) basis.

But these metrics suggest the dollar has been overvalued for quite some time, and valuation alone has not been enough to bring it back down. For a longer term decline to set in, there must be one or more catalysts. These are a few we are watching that could influence the direction of the dollar.

1. Interest rate differential between the U.S. and Europe is narrowing

In the pre-COVID era, interest rates were low in all the major economies. Nevertheless, rates in the U.S. were higher than those in Europe, Japan and other developed markets. That was the primary factor propelling the U.S. dollar higher against most currencies. Investors around the world could earn higher interest rates while enjoying safe haven status. High forward interest rates also meant investors could buy bonds denominated in the euro and the yen, hedge them into U.S. dollars and earn a higher interest rate (carry).

The U.S. dollar is significantly above long-term average

Chart shows the monthly real, or inflation-adjusted, value of the dollar since March 1980 and a 10-year moving average of the real broad effective exchange rate over the same period. The U.S. dollar index was 107 in March 1980. The index reached its lowest point of 93 in August 2011 and rose to a cycle peak of 132 in November 2022. The March 2023 value is 125. The dollar index has been running above its long-term average since 2015 and by an increasing margin until November’s peak.

Sources: Capital Group, J.P. Morgan. Data as of March 31, 2023. The real broad effective exchange rate measures the value of the U.S. dollar against a group of developed and emerging market currencies and adjusts for inflation using the U.S. Consumer Price Index (CPI). CPI is a commonly used measure of inflation that measures the average change over time in the prices paid by consumers for a basket of goods and services.

Several factors supported comparatively higher U.S. nominal and real interest rates: a hawkish Federal Reserve more determined to raise interest rates than the European Central Bank (ECB), the Bank of England (BOE) or the Bank of Japan (BOJ), plus a strong and productive U.S. economy and higher inflation.

Now this picture is changing, especially relative to the euro. The swift collapse of three U.S. regional banks — Silicon Valley Bank, Signature Bank and Silvergate Bank — has led bond markets to lower expectations for both the terminal federal funds rate and U.S. Treasuries across the yield curve. Meanwhile, European bond yields could still move higher as the ECB stays on its rate-hiking path should inflation pressures persist.

It’s also been interesting to see that in the most recent episode of market volatility attributable to the banking sector, the dollar has hovered in a range of 92 to 94 cents to the euro. Swift action by the Federal Reserve to provide dollar liquidity via swap lines with other central banks provided support to the U.S. currency. (Swap lines are agreements between two central banks to exchange currencies. They allow a central bank to obtain foreign currency from the central bank that issues it and distribute it to commercial banks in their country.)

Overall we expect the differential between U.S. interest rates and those in Europe to narrow. This could remove some support for the dollar, which was trading around 92 cents to the euro as of March 31.

One reason for a potential narrowing: The ECB started hiking later than the Fed. After raising rates by 250 basis points (bps) last year, the ECB probably has further to go if it wants to bring inflation closer to its 2% target. Meanwhile, the Fed may be closer to pausing, or potentially cutting rates, than it had anticipated before the U.S. bank failures. Markets expect the rate gap to decrease by about 90 bps (from around 1.8% to 0.9%) by the end of the year.

Meanwhile, the BOE increased its policy rate by nearly 425 bps, putting U.K. nominal and real interest rates closer to the U.S. than either the ECB or the BOJ. Its actions helped lift the pound 15% against the U.S. dollar after U.K. government turmoil forced it to an all-time low in September 2022. What happens next to the pound sterling will likely depend more on potential further rate hikes than any other variable. At this point, the BOE seems less aggressive than the ECB or the Fed.

The dollar follows real rates

From the start of 2021 to early November 2022, the real yield difference rose from 0.1 percent to 1.9 percent, and the dollar index rose from 118 to 137. Both have declined since November. As of March 29, 2023, the real yield difference is 1.2 percent and the dollar index is 128.

The 10-year real rate differential measures the difference in inflation-adjusted interest rates between the U.S. and a developed market group consisting of Germany, Japan and the U.K. The broad U.S. dollar index is an effective exchange rate that measures the value of the U.S. dollar against a group of developed and emerging market currencies.

2. Economic outlook across various markets and countries is improving

Growth prospects for China, Europe, Japan and emerging markets are looking brighter. Just a few months ago, China’s economy was hampered by the government’s zero-COVID policy, Europe was facing a potential winter energy crisis, Japan’s economy unexpectedly contracted in the third quarter and the risk of a global recession loomed over emerging markets.

China’s sooner-than-expected economic reopening improves 2023 growth prospects for the country as well as the rest of the global economy. After years of being trapped at home, many Chinese consumers have the savings and demand to fuel spending. Measures of consumer activity and manufacturing already show signs of improvement. China’s government has been providing billions of dollars to shore up its ailing property market and also appears closer to wrapping up reforms for private sector technology companies.

2023 global growth outlook improves

Economic growth projections improved in the January update. Projected real GDP growth for the world went from 2.7 percent in October to 2.9 percent in January. U.S. projections went from 1.0 percent to 1.4 percent. Euro-area projections went from 0.5 percent to 0.7 percent. Japan projections went from 1.6 percent to 1.8 percent. Emerging and developing markets projections went from 3.7 percent to 4.0 percent. China projections went from 4.4 percent to 5.2 percent.

European economic data show reduced risks of a deep recession, as forward-looking manufacturing and service sector Purchasing Managers’ Index (PMI) data point to better conditions. The sharp reversal in energy prices due to a warm winter is helping manufacturers and consumers.

Japan’s economy is also proving to be resilient. Consumer demand is holding up despite higher inflation. The service sector shows signs of improving, the labour market remains tight and manufacturing should get support from China’s recovery. Corporate investment may also be improving.

3. Portfolio flows may begin to support the euro

In recent years the ECB’s negative interest rate policy and quantitative easing measures kept foreign investors away, but those policies look set to change. If policy rates between the ECB and the Fed narrow as expected, another driver of euro weakness and dollar support is likely to dissipate.

Europeans have been buying far more foreign bonds than international investors have been buying into Europe. As a result, the five-year moving average for net bond flows in Europe has been negative since 2014. While it’s hard to pinpoint, a majority of outflows likely went to the U.S., given the market’s liquidity and size.

Chart shows eurozone bond purchases abroad (outflows) and foreign purchases of eurozone bonds (inflows). In December 2008, the five-year moving average of net bond flows showed inflows exceeded outflows by 400 million euros. Starting in 2014, the five-year moving average of net bond flows showed outflows exceeding inflows. Net bond outflows were nearly 2 trillion euros at the beginning of 2022, and 1.4 trillion euros as of December 31, 2022.

Sources: Capital Group, Haver Analytics. Data as of December 31, 2022. Outflows = eurozone bond purchases abroad. Inflows = foreign purchases of eurozone bonds. Data start date is December 2008.

Meanwhile, the carry advantage between the U.S. and the eurozone is becoming less compelling. When the Fed aggressively hiked rates before the ECB, an attractive carry opportunity arose. Even after the cost of hedging currency risk, using euro-denominated assets to buy dollar assets was attractive. However, that hedged trade is becoming less profitable, which should reduce euro selling and flows into the dollar.

4. A rising Japanese yen: possible but fragile

The Bank of Japan’s extreme monetary policies have long kept the yen from appreciating against the dollar. The BOJ has implemented yield curve control (YCC) — pegging 10-year government bond yields near zero rate — as well as negative interest rates and massive quantitative easing to pump inflation closer to its 2% target.

Signs of stronger inflation may finally be here. Japan’s core consumer price index, which excludes fresh food, rose 4.2% year over year in January. And some companies appear to be complying with BOJ Governor Haruhiko Kuroda’s call for wage increases above the rate of inflation.

If the BOJ believes inflation can stay around 2%, it will have cover to gradually unwind some of its policies. In a surprise move last December, the central bank loosened its YCC policy slightly, and we expect it to make a similar announcement this year.

Allowing 10-year yields to rise should support the yen. Trading around ¥133 to the dollar, it is among the most undervalued currencies, according to our currency analyst Jens Søndergaard’s valuation model. Even slightly higher domestic rates would incrementally reduce Japanese dollar demand.

In addition, an increase in Japanese interest rates and potential volatility from BOJ policy uncertainty could make carry trades more expensive. However, the interest rate differential between the yen and the dollar also depends on Fed action. If stubborn inflation pressures force the Fed to raise rates beyond current expectations, the yen could remain depressed.

5. Emerging markets are further along the curve on monetary policy

When inflation picked up in 2021, emerging market (EM) central banks responded quickly and aggressively. Latin American central banks led the charge. Brazil’s central bank started hiking rates in March 2021 and took its policy rate from 2.00% to the current 13.75%. Eastern European central banks picked up their pace after Russia’s invasion of Ukraine. And the spike in energy prices last year led some Asian central banks to increase rates.

EM central banks raised rates aggressively

Chart shows central bank policy rates for select emerging markets and the U.S. Since the end of 2020, key emerging market central banks have increased rates above the U.S. Federal Reserve. From the end of 2020 through March 2023, the fed funds rate increased 475 basis points to 5.00 percent. One hundred basis points equals one percentage point. Among emerging markets, Brazil raised rates 1175 basis points to 13.75 percent. Chile raised rates 1075 basis points to 11.25 percent. Colombia raised rates 1125 basis points to 13.00 percent. Czech Republic raised rates 675 basis points to 7.00 percent. Hungary raised rates 1240 basis points to 13.00 percent. Mexico raised rates 700 basis points to 11.25 percent. Peru raised rates 750 basis points to 7.75 percent. Poland raised rates 665 basis points 6.75 percent. Romania raised rates 550 basis points to 7.00 percent.

High interest rates in nominal and real terms have been supportive of EM currencies, which have attracted investors looking for income. The Brazilian real and Mexican peso were among the few currencies that strengthened against the U.S. dollar last year. In addition to attractive nominal and real yields, macroeconomic conditions have improved. The tilt toward more positive fundamentals is likely to continue overriding political risk concerns in those countries for now.

In many Asian economies, a combination of attractive interest rates, improving growth prospects and strong macroeconomic fundamentals are supportive of currencies.

China’s economic reopening should broadly boost Asian growth. In Southeast Asia, we believe the Thai baht is becoming more compelling as increased tourism drives up economic growth rates and foreign flows. A rebound in commodity exports from Indonesia to China may benefit the Indonesian rupiah.

The Korean won also appears to be undervalued. Exports to China will likely rebound, and Korea’s financial position could get stronger. As a large energy importer, Korea faced a severe headwind from last year’s jump in prices — hurting businesses and consumers — but the drag should lessen significantly this year.

Further support to EM currencies could come when the Fed stops raising rates. In that case, EM central banks may find it easier to lower their policy rates, especially if inflation keeps easing or growth softens. That said, the rate differential between many emerging markets and the U.S. will likely remain attractive, providing a potential tailwind to EM currencies.

What are the risks to this view?

If the global economy weakens more than expected as the full impact of monetary tightening makes its way through the system, the U.S. dollar could find support given its status as a safe haven currency. This would likely delay a repricing of the dollar to its fair value.

A long-term U.S. dollar decline also requires Europe, Japan, China and other emerging markets to show substantial improvement in economic fundamentals, including gains in productivity and economic reforms favoring free enterprise and capital investments. Over the past decade, the U.S. economy has gained its edge from technology and health care innovations as well as an economic incentive system that supports entrepreneurship.

While it is early, we do see modest signs of change. In Europe, Italy has laid out a post-pandemic recovery and resilience plan. If properly executed, it would be meaningful, as Italy has been a European growth headwind for many years. Germany is breaking from its long-held stance of fiscal conservatism and is willing to provide a boost to consumers and industries even if it means running larger deficits along with other EU members. And while increased fiscal spending in Europe should stimulate growth, it’s unclear how it will affect inflation and the ECB’s efforts.

Other conditions in Europe are also looking more favourable. Fears of a peripheral debt crisis or a eurozone breakup have decreased. The eurozone’s responses to Brexit, the pandemic and Russia’s invasion of Ukraine appear to have helped reassure investors that the region is a safer place to invest than it was a decade ago.

Japan is starting on a slow path of normalizing its monetary policy while providing some support to the economy. Meanwhile, many of the large emerging markets have shown monetary discipline by keeping rates high in the face of inflation and tempering fiscal stimulus. But a structural and sustained uplift in financial assets, including currencies, will depend on economic reforms varying from labour and land acquisition laws to intellectual property protection and joint venture policies.
