Executive Summary
Emerging Market Debt (EMD) has evolved from a niche allocation into a large, diverse and increasingly resilient fixed income universe. Its recent performance, improving credit quality and differentiated return drivers suggest that investors may need to rethink long-standing assumptions about the asset class. As macro conditions become more fragmented, EMD may offer investors a differentiated source of total return and greater portfolio diversification.
Competitive returns with stronger risk-adjusted outcomes
Sovereign USD EMD, as represented by the JPM EMBI Global Diversified (EMBIGD) Index, has outperformed both US and European investment grade (IG)/ high yield (HY) blended bond portfolios over the 1-, 3-, 5- and 20-year horizons on a total return basis. The blended portfolios have similar credit-quality profiles - the EMBIGD Index comprises both investment grade (IG) and high yield (HY) sovereign bonds, while the US and European blended bond portfolios also combine both IG and HY bonds from their respective markets.
Compared to the US and European blended bond portfolios, EMD delivered superior risk-adjusted returns over the 1- and 3-year horizons, with Sharpe ratios of 1.61 and 1.22 respectively, supported by EMD’s higher returns and lower volatility. Fig.1.

Source: Eastspring Investments, Bloomberg, in USD terms, as of 31 July 2026. The JPM EMBI Global Diversified index (JPEIDIVR) has 47.22% in IG bonds and 52.78% in HY bonds. For fairer comparison, we constructed US IG/ HY blended and Pan-European
IG/ HY blended portfolios which also have compositions of 47.22% IG and 52.78% HY bonds.
Returns are annualised arithmetic mean simple daily returns scaled by 252 trading days. Annualised volatility is the standard deviation of simple
daily returns scaled by √252. Blended daily returns are computed as the weighted sum of component simple daily returns.
Sharpe ratios use the geometric CAGR of the J.P. Morgan GBI US Government Bond Total Return Index (JPMTUS Index)
over each respective horizon as the risk-free rate.
All figures are in USD unhedged terms; European index returns reflect EUR/USD currency effects.
The case for EMD as a strategic bond allocation becomes even more compelling when evaluated as a complement to developed market (DM) bond portfolios. Our analysis based on 5 years of data shows that adding a 10% allocation of EMD to a blended US (50% IG/ 50% HY) and a blended European (50% IG/50% HY) bond portfolio improves the portfolio’s overall risk-adjusted returns, as measured by the Sharpe ratio. Fig. 2. Yet, many investors remain under allocated to EMD given lingering risk perceptions.

From niche allocation to strategic bond market
EMD is no longer the narrow distressed-debt niche of the 1990s. It is broader, higher quality and more investable than many investors assume. As of December 2025, total Global EM tradable debt amounted to USD52tn or ~31% of global bonds outstanding, slightly behind the US, and ahead of the European Union. Fig. 3.

EMs is a powerful engine of global growth. By 2031, the International Monetary Fund (IMF) expects EMs to account for almost 75% of nominal global growth. Fig. 4. As EM economies continue to grow faster than developed markets, their economic importance and relevance within global portfolios is likely to increase. A broader and deeper EMD universe gives global bond investors more ways to access EM growth and income.

EMD has become more resilient
While investors have traditionally looked to DMs and DM bonds for greater stability, EMs have spent the past three decades strengthening their market structures, institutions and ability to manage crises. The growing resilience of the EM economies can be seen from the shift in bond credit quality - the percentage of IG-rated USD denominated EM sovereign bonds rose to above 50% in 2025 up from 0% in 1991.

Over the past years, several large EM central banks have lowered/narrowed their inflation target ranges resulting in greater currency stability and more attractive local debt markets. By contrast, inflation in several developed markets remains above target, while larger fiscal needs and structurally higher social spending may challenge the path back to sustainably lower inflation. The IMF forecasts DM’s share of gross government debt to Gross Domestic Product (GDP) to reach 114% by 2031, above the EM’s 86%. See Fig. 6. Long-term bond yields in the US, France, UK and Japan have risen, driven by concerns over their economies’ long-term fiscal sustainability.

EM issuers have also increasingly diversified their funding currencies beyond their domestic currencies and the USD, to include CNY, CNH, AUD and JPY. This potentially reduces costs and their reliance on a single funding market, making the EMD universe more resilient.
A broader opportunity set with diversification benefits
The EMs offer a rich opportunity set consisting of over 70 countries that are highly diverse in terms of economic structure, demographics and stages of development. Fig. 7. This diversity creates economic and policy dispersion which presents opportunities for active managers.

Given EM’s diverse economic drivers, EMD’s return profile can differ from traditional DM bond and equity exposures. EMD has a relatively low correlation with US Treasuries at 0.32, providing bond investors with diversification benefits. In addition, while EMD is affected by global risk sentiment, it is less correlated to global, US and European equities than US and European HY bonds. Fig. 8.

Why EMD now
The case for EMD is stronger today because global macro conditions are becoming more fragmented. Artificial Intelligence (AI) disruption, geopolitical tensions, shifting trade alliances and energy security concerns are creating greater dispersion across growth, inflation, policy rates and currencies within the EMs. For active investors, this dispersion creates multiple opportunities.
Valuations also remain supportive in selected markets. Despite recent turbulence in the Middle East and higher global bond yields, real rates are still attractive in parts of Central and Eastern Europe, Middle East and Africa (CEEMEA) as well as in Latin America. Fig. 9.

With macro dispersion rising globally and return drivers becoming more differentiated, the risk for global bond investors may no longer be simply whether to allocate to EMD, but whether staying under-allocated could mean missing a more resilient, diversified and increasingly relevant source of total returns.
