A Rare Shift: Can Emerging Market Outperformance Last?

2025 has been an exceptional year for emerging market (EM) equities. South Korea has surged almost 80%, while South Africa, Brazil, and Mexico have each posted gains of more than 40% year to date. Within the MSCI country universe, six of the top 10 performers this year are emerging markets. This level of outperformance relative to the U.S. at the broad asset class level has been rare and, barring a strong late-year rotation, this will mark only the third time in the past 15 years that emerging markets have outperformed U.S. equities.

EM Equities Have Handily Outpaced U.S. Equities this Year

Can this trend persist or is it merely a one-year aberration? Much of the answer likely depends on the U.S. dollar, as the dollar’s trajectory has historically been the single most important driver of international equity performance compared to the U.S. When the dollar weakens, it encourages capital to search outside the U.S. for investment opportunities; when it strengthens, capital gravitates back to the U.S. in search of returns. These dynamics often reinforce themselves, as we’ve seen over the past decade where dollar strength fueled U.S. equity outperformance, which in turn supported further dollar strength.

The last extended period of EM outperformance occurred during the 2002–2008 cyclical bear market in the dollar. Over that span, the Dollar Index declined roughly 40% from peak to trough, creating a favorable backdrop for international equities. Interestingly, this episode followed a long period of U.S. dominance during the dot-com boom of the 1990s, when strong dollar conditions and technology-led growth kept global capital anchored in U.S. markets. Fast forward to 2025 and dollar weakness, particularly in the first half, has been a key driver behind strong gains in EM. However, the critical question for investors is whether this year’s move signals the start of a multi-year dollar downtrend similar to the early 2000s, or if it is merely a temporary correction within a longer-term bullish cycle. The evidence so far is mixed. While the Dollar Index is down about 8% year to date and arguably still above fair value, it remains within the broader uptrend that has persisted since 2011.
