Managing your investments has never been easier!
Emerging-market (EM) debt has grown up. What was once a niche corner of fixed income is now a mainstream building block for globally diversified portfolios. Emerging market bonds can lift portfolio yield and add sources of return that don't move in lockstep with U.S. assets. But those benefits come with distinct risks—so the key is knowing which slice of emerging markets debt you own, why you own it, and when it makes sense.
This guide reframes the landscape for investors: the major types of emerging market bonds, how the risk/return levers differ, where the biggest pitfalls lie, and how to access the market efficiently via ETFs and other investment vehicles.
These are government bonds issued by developing countries but denominated in a major currency (mostly U.S. dollars). For U.S. investors, you're largely credit-spread–driven: your return hinges on whether the issuer's credit quality improves or deteriorates compared with U.S. Treasury bonds. Currency swings of the issuer can still matter—if a country's local currency plunges, its ability to service dollar debt weakens, raising default risk—but your bond's cash flows are in USD.
A quick reference point: as of late September 2025, the iShares EMB ETF (USD sovereigns) lists an index yield to maturity around 6.1% and an option-adjusted spread near 200 bps versus Treasuries—figures that will move with the cycle. These emerging market bonds often offer higher yields compared to investment-grade bonds from developed nations.
Here, governments of developing countries borrow in their own currencies. Foreign investors take on three return drivers: local interest rates, the issuer's credit quality, and FX moves versus the dollar. This segment is large and liquid—historically about ~85% of overall emerging market debt outstanding has been local rather than external—so it plays an outsized role in global fixed income. It also tends to be less correlated with U.S. bonds, offering diversification benefits. State Street's long-horizon data show the correlation of local-currency EM sovereigns to the Bloomberg U.S. Aggregate at ~0.45 (July 2008–September 2024).
Corporate bond issuances from emerging market companies—often export-oriented and globally competitive—have matured into a deep investable universe. The JPMorgan CEMBI tracks hundreds of issuers across sectors, which allows investors to diversify not only by country but also by industry. Historically, default experience for high-yield EM corporates has, at times, compared favorably to EM sovereign high-yield. During the COVID shock (mid-2020), JP Morgan data cited by Loomis Sayles showed a 15.8% default rate in the EM HY sovereign index versus 2.3% for EM HY corporates, underscoring that "sovereign ceiling" isn't a law of nature.
For years, many governments in developing nations suffered from "original sin": they couldn't borrow abroad in their own currency, so they piled up dollar debt and absorbed the currency risk themselves. As local markets deepened, more governments shifted to local-currency funding—passing currency risk to foreign investors who buy those bonds. That shift improves sovereign resilience but changes your risk mix: owning local debt means you must have a view on inflation, monetary policies, and the currency path—not just credit.
At the same time, the corporate bond market "decoupled" from sovereigns in many countries: strong, globally integrated companies sometimes boast sturdier balance sheets than their own governments. That's why emerging market corporate bonds deserve analysis at the sector and issuer level, not merely by country spread.
Sovereign defaults are messy but rarely mean a total wipe-out; they typically lead to restructurings that stretch maturities and cut coupons/principal. In May 2020, Argentina missed a $500 million coupon payment and ultimately restructured roughly $66–$69 billion of foreign bonds with high participation; analysts estimated meaningful present-value haircuts for creditors. This event highlighted the credit risk inherent in emerging market bonds.
Takeaway: In hard-currency sovereigns, credit cycles and policy credibility matter as much as growth.
Unorthodox monetary policies—especially rate cuts into high inflation—have repeatedly destabilized Turkey's lira, roiling both local and hard-currency debt. In late 2021, the lira plunged and local 10-year yields spiked; more recently, Turkey has been unwinding costly FX-protected deposit schemes as it re-embraces orthodoxy. FX swings drive servicing costs for USD borrowers and can paralyze primary markets. This case illustrates the currency volatility risk in emerging markets debt.
Takeaway: In emerging markets, policy frameworks and FX regimes are central to bond risk, not a footnote.
After a polarized 2022 election, markets fretted about fiscal anchors and governance at state-influenced firms. Headlines around Petrobras leadership and policy have periodically jolted asset prices, even as Brazil's macro metrics today show gross public debt near the high-70s% of GDP and better-than-feared fiscal prints in 2025. Political direction can change risk premia quickly—even without recession. This example highlights the political instability risk in developing countries.
Takeaway: For emerging market debt, politics can move spreads (and FX) in ways that fundamentals alone won't predict.
Emerging market bond markets are less liquid than U.S. credit. In stress, bid-ask spreads widen and ETFs can gap more than their U.S. counterparts. Liquidity can vanish not only from local shocks but also from global USD shortages tied to Fed policy turns, banking stress, or geopolitics—so price moves can overshoot. (This is why implementation and position sizing matter.)
Historically, emerging market bonds have tended to do better when:
ETFs and other investment vehicles make emerging markets debt accessible and diversified for U.S. investors:
Emerging market bonds can raise yield and broaden your return streams, but they're not set-and-forget. The same forces that create opportunity—policy change, currency dynamics, evolving institutions—also generate risk. Use ETFs to calibrate which risks you want:
Anchor these sleeves to the macro regime, keep position sizes sensible, and always diversify. Remember that emerging markets debt encompasses a wide range of instruments, from Brady bonds to Yankee bonds, and includes regions like Latin America and Eastern Europe. Each sub-category within this asset class offers unique risk-return profiles and exposure to various economic factors in developing nations.
