Emerging market debt: Weathering the Treasury sell-off
Despite a sharp rise in US Treasury yields, a look at why attractive income, improving fundamentals, and diverse return drivers continue to support our case for emerging market fixed income.

Key takeaways
- Emerging market debt has weathered the Treasury sell-off. The US 10-year yield has risen above 5.2%, yet emerging market sovereign spreads remained contained. Frontier and other issuers continue to price new deals into healthy demand.1
- Higher starting yields provide a meaningful income cushion. We believe yields of around 7.1% in hard currency sovereigns, 8.1% in sovereign high yield, and above 9.0% in frontier markets give investors a meaningful buffer against volatility.2,3,4
- Emerging market debt is more than a US duration trade. Sovereign credit, local rates, currencies, corporates, and frontier markets each respond to different forces, so not every part of the asset class needs to perform at the same time.
- The old foreign exchange playbook isn't holding. Emerging market central banks tightened early and hard, and external balances have improved. High-carry currencies such as the Paraguayan guarani, Kazakh tenge, and Nigerian naira have gained against the dollar despite rising Treasury yields.
- Corporates add ballast. Moderate leverage, solid interest cover, contained defaults into 2027, and shorter duration have kept emerging market corporate high yield positive through the sell-off.
US Treasury yields have risen sharply – normally a difficult backdrop for emerging market debt. Yet emerging market debt (EMD) has proved resilient. Higher starting yields, stronger fundamentals, healthy primary market demand and a broader range of return drivers mean today’s EMD market looks very different from the one investors may remember from previous rising rate cycles.
The US 10-year Treasury yield has climbed from below 4.0% in early March to above 5.2% at the end of September.5,1 Historically, that combination of higher US yields and tighter global financial conditions would have been expected to put significant pressure on EMD. So far, that pressure has been contained.
EM sovereign spreads are only around 9 bps wider year to date (YTD), after a bout of widening in the final trading sessions of September.6 Against a rise of more than 110 bps in the US 10-year yield, we believe that is a modest move – and well short of the spread blow-outs that have typically accompanied past Treasury sell-offs (Chart 1).1 Meanwhile, several parts of the asset class – particularly frontier and high yield (HY) sovereign debt – have continued to generate positive returns.4,2
Chart 1. US 10-year Treasury yield vs. EMBI Global Diversified Index spread*
Source: Bloomberg, September 2026. *Note: The step‑down in the EMBI Global Diversified spread on 4 September 2026 reflects a change in J.P. Morgan's index methodology, not a change in market conditions. From that date, defaulted securities – which still contribute to index returns – are excluded from the aggregation of headline analytics (yield, spread, duration). JP Morgan estimated the one‑off impact at approximately 25 bps of spread tightening for the EMBI Global Diversified."
That resilience matters. In our view, it suggests EMD is increasingly being driven by more than simply the direction of US interest rates.
Resilience is also visible in the primary market.
Despite higher Treasury yields, EM issuers have continued to access markets, and new supply has been met by healthy investor demand. Frontier issuers including Ecuador, Gabon, the Democratic Republic of Congo, and Pakistan have all accessed the Eurobond market. This does not imply that default risk has fallen uniformly across Frontier markets. But continued market access is important. We believe it gives issuers another source of funding and refinancing, while demand for new deals demonstrates that investors remain willing to provide capital where yields and country fundamentals are sufficiently attractive.
Higher underlying Treasury rates mean new bonds are coming to market with more attractive all-in yields, giving investors, in our view, greater income from the outset. Combined with still-light positioning in EMs following several years of outflows, this has helped create a supportive technical backdrop even as US yields have moved higher.
In other words, higher Treasury yields have raised the hurdle, but they have also improved the opportunity set for investors willing to take a selective approach.
More than a duration trade
The key is breadth. EMD is not a single market. Hard currency sovereign bonds combine Treasury exposure with sovereign credit spreads. Local currency debt is driven by domestic interest rates and currencies. Corporate bonds add company-specific fundamentals, while frontier markets are often influenced by reforms, International Monetary Fund programs, and country-specific developments. Those different return engines have been particularly valuable this year.
Longer duration investment-grade (IG) sovereign debt has naturally been more exposed to rising Treasury yields. But frontier sovereigns have returned 3.97%, sovereign HY 2.23%, and EM corporate HY 3.29% all YTD, respectfully, as carry and improving credit fundamentals have helped offset the rise in underlying US rates.4,2,7
Frontier markets are a particularly good example. Lower integration with global capital markets, shorter duration, and greater sensitivity to domestic reforms have resulted in very low long-term correlation with US Treasuries (Table 1). In an environment where US rates are dominating developed market (DM) fixed income, that differentiation can be valuable.

Local markets are also breaking the old pattern
The traditional playbook says higher US yields should mean a stronger dollar and weaker EM currencies. But that relationship has been far less straightforward this time.
Many EM central banks tightened policy earlier and more aggressively than DM peers, leaving relatively high nominal and real yields. At the same time, external balances and foreign exchange reserves have improved across several countries. That has created opportunities in selected local markets. For example, high carry frontier currencies including Paraguayan guarani, Kazakh tenge, and Nigerian naira, have all generated strong positive returns against the US dollar this year despite the rise in Treasury yields.
That does not make EM currencies immune to further dollar strength. But, in our view, it does underline an important point: domestic fundamentals increasingly matter (Chart 2).

Corporate fundamentals provide another buffer
EM corporates add another source of resilience. Balance sheets remain relatively healthy, with moderate leverage compared with many DM peers and solid interest coverage across much of the universe. Default rates are expected to remain contained into 2027, while EM corporate bonds also typically carry less duration than IG sovereign debt. That combination of healthy fundamentals, shorter duration, and attractive carry has helped EM corporate HY deliver positive returns despite the Treasury sell-off.
Again, the message is not that higher US yields do not matter. It is that they are only one part of the return equation.
Why emerging market debt?
For investors, we believe the following features stand out:
- Income. Yields across EMD are attractive at around 7.1% for broad hard currency sovereign debt, 8.1% for sovereign HY, and more than 9.0% in frontier markets.2,3,4 That carry provides a meaningful cushion against market volatility.
- Diversification. Sovereign credit, local rates, currencies, corporates, and frontier markets respond to different economic and market forces. Investors therefore do not need every part of EMD to perform at the same time.
- Fundamentals. In our view, many EMs enter this period of tighter financial conditions with stronger policy frameworks, healthier external balances, and relatively solid corporate fundamentals.
Final thoughts
If this year has demonstrated anything, it is that the old rising rate playbook is becoming a less reliable guide to EMD. Higher US yields remain an important influence, but the asset class has shown resilience through attractive carry, improving fundamentals, and a broad opportunity set across sovereigns, corporates, local markets, and frontier debt. Moreover, with markets already pricing close to 100 bps of additional Fed hikes over the next 12 months, we believe any moderation in that path could provide a further tailwind for EMD.[8]

Past performance is not an indication of future results.
Diversification does not ensure a profit or protect against a loss in a declining market.
Projections are offered as opinion and are not reflective of potential performance. Projections are not guaranteed and actual events or results may differ materially.
Fixed income securities are subject to certain risks including, but not limited to: interest rate (changes in interest rates may cause a decline in the market value of an investment), credit (changes in the financial condition of the issuer, borrower, counterparty, or underlying collateral), prepayment (debt issuers may repay or refinance their loans or obligations earlier than anticipated), call (some bonds allow the issuer to call a bond for redemption before it matures), and extension (principal repayments may not occur as quickly as anticipated, causing the expected maturity of a security to increase).
Foreign securities are more volatile, harder to price and less liquid than U.S. securities. They are subject to different accounting and regulatory standards, and political and economic risks. These risks are enhanced in emerging markets countries.
