Local-currency emerging-market debt outperformed dollar-denominated alternatives across major indices in 2025, delivering 9 percent to 19 percent returns in U.S. dollar terms—the strongest showing since 2019. The performance reversal reflects a structural shift in investor composition: as U.S. Treasury yields rose, foreign capital retreated, leaving domestic institutional buyers to absorb new issuances.
The data on foreign ownership tells the story. Foreign holders of Mexican local-currency bonds fell to 11 percent of the market from 29 percent in early 2020. Indonesia saw a steeper drop, from nearly 40 percent foreign ownership to 13 percent. Brazil, India and South Africa all experienced similar patterns, with domestic pension funds, banks and insurance companies replacing foreign capital as the marginal buyer.
This substitution matters structurally. Domestic institutional holders typically buy to maturity, creating stable demand insensitive to global risk-off events. Foreign portfolio investors, by contrast, exit rapidly during market dislocations. The shift from 40 percent to 13 percent foreign ownership in Indonesia represents a permanent change in the underlying demand curve, not a cyclical retreat.
The local-currency market itself dwarfs its dollar-denominated peer. As of August 2025, the local-currency universe reached approximately $6.7 trillion, more than six times the $1 trillion hard-currency sovereign and corporate debt market. JPMorgan's new GBI-EM Edge frontier index—launching by September 2026—will track roughly $330 billion across 26 countries, with Africa at 45 percent weighting and average nominal yields of 10.4 percent.
Three factors sustain the outperformance. First, elevated domestic institutional ownership reduces volatility and creates predictable demand for new debt. Second, many emerging-market central banks hiked rates aggressively during the post-pandemic inflation cycle, generating historically generous real yields. Third, numerous emerging-market currencies remain undervalued on purchasing-power-parity metrics, creating potential for capital appreciation beyond coupon income.
The thesis faces two material counterarguments. A strengthening U.S. dollar during the second half of 2026 would erode currency-appreciation gains and potentially reverse foreign capital inflows. A global growth slowdown would test the stability of domestic demand, particularly if local institutional buyers face redemption pressure. However, the scale of the foreign capital exit—from 29 percent to 11 percent in Mexico over five years—suggests that threshold effects are already embedded in pricing.
