International & Sovereign Bonds

Government bonds don't only come from the UK and US. Every major economy issues sovereign debt, and the yields on those bonds tell you something important about each country's economic health, political risk, and inflation outlook. International bond markets are enormous — and genuinely interesting once you understand what drives the differences between them.

Sovereign bonds — the full spectrum

Every country that issues bonds in its own currency is technically borrowing in money it can print — which is why developed market sovereign defaults are rare (a government can always inflate away domestic debt, though this destroys the purchasing power of bondholders). The spectrum of sovereign risk runs roughly from:

• US Treasuries and UK Gilts — considered risk-free in nominal terms; the global benchmark
• German Bunds, Japanese JGBs — major developed market bonds, very high quality
• Southern European (Italy, Spain, Greece) — eurozone members who can't print their own currency; genuine default risk, as Greece demonstrated in 2012
• Emerging market sovereigns (Brazil, India, Turkey, Egypt) — higher yields, higher risk, currency volatility

The spread — measuring relative risk

Sovereign bond yields are typically quoted as a spread above US Treasuries or German Bunds. Italian 10-year yields at 200 basis points (2%) above German Bunds means markets are demanding extra return for the additional risk of holding Italian rather than German government debt. When this spread widens during a crisis, it signals market stress about that country's fiscal position.

Eurobonds and the currency question

Eurobonds are bonds issued in a currency other than the issuer's home currency — a Brazilian company issuing bonds in US dollars, for example. They allow issuers to access the deep, liquid US dollar or euro debt markets. For investors, they remove local currency volatility but add credit risk if the issuer's home currency weakens (making dollar repayments more expensive).

When emerging market governments borrow in US dollars (hard currency debt), they face a dangerous dynamic: if their own currency weakens dramatically, the real cost of servicing dollar debt explodes. Argentina, Turkey, and Sri Lanka have all experienced debt crises partly driven by this mismatch.

Emerging market bond funds

For most investors, EM bonds are accessed through ETFs. The key distinction is hard currency EM debt (bonds issued in USD — less currency risk for USD investors, more for the issuer) vs local currency EM debt (bonds in the issuer's home currency — you take on full currency risk but sometimes earn higher yields). Local currency EM debt is more volatile but can outperform significantly when EM currencies strengthen.
