What Is a Sovereign Bond?
Sovereign bonds are key tools used by governments to secure funding for national needs ranging from infrastructure to debt repayment. These bonds are issued either in domestic or foreign currencies. They offer varying levels of safety and yield based on the issuing country’s financial health.
Interest rate payments and principal repayment are determined by the government’s risk profile, which can change with economic and political shifts. Investing in sovereign bonds can be a strategic choice for diversifying portfolios for investors who understand these risks.
How Sovereign Bonds Work
Like any bond, sovereign debt entitles owners to periodic interest payments from the issuer—in this case the government—with repayment of the bond’s face value when its term matures.
The interest rate or yield depends on the issuer’s risk profile. Countries at higher default risk offer higher yields.
Rating agencies assess sovereign bonds based on economic factors, exchange rates, debts, and political stability to predict default risk.
Rating agencies including Standard & Poor’s, Moody’s, and Fitch Ratings provide sovereign credit ratings for investors seeking to evaluate the risks involved in investing in a specific country. The same agencies provide credit ratings on corporations and the bonds they issue.
Currency Factors in Sovereign Bonds
Some developing countries can’t attract foreign investment in bonds denominated in their domestic currency because foreign investors are unwilling to assume the additional risk of a fluctuating currency. Their currency markets may not be sufficiently liquid, or investors may be wary that the currency will lose value, eroding their rate of return.
Countries borrowing in a foreign currency face similar currency exchange risk and higher borrowing costs if the domestic currency loses value against the one in which the sovereign bond is denominated.
For example, say the Indonesian government issues bonds denominated in the Japanese yen to raise capital. It agrees to a nominal annual interest rate of 5%. During the bonds’ term, the Indonesian rupiah depreciates by 10% annually versus the yen. As a result, the real interest rate on the yen-denominated debt to the Indonesian government will be 15% in rupiah terms.
Important
In August 2023, Fitch Ratings downgraded the U.S. from AAA to AA+ due to fiscal deterioration, rising debt, and weakened governance. The agency cited the repeated debt limit standoffs and their 11th-hour resolutions by Congress.
Investment Strategies for Sovereign Bonds
You can easily invest in U.S. sovereign bonds on the TreasuryDirect.gov website.
Buying foreign bonds is more complex and typically requires a broker, a foreign trading account, and purchasing bonds at the market price. This route can be limiting, depending on what bonds are available, and the transaction costs can be high.
A simpler option is to buy U.S. mutual funds or ETFs that hold foreign sovereign bonds, which offer diversification and reduced risk due to exposure to a variety of foreign bond issues.
Popular foreign sovereign bond ETFs include:
- iShares International Treasury Bond ETF (IGOV)
- SPDR Bloomberg International Treasury Bond ETF (BWX)
- SPDR Bloomberg Capital Short Term International Treasury Bond ETF (BWZ)
- Franklin Liberty International Aggregate Bond ETF (FLIA)
What Are Sovereign Bond Yields?
Sovereign bond yields are the interest rate a government pays to buyers of its sovereign bonds. These are debt securities issued by a national government to raise capital. As with corporate bonds, sovereign bond yields are higher than average for risky issuers and lower than average for highly-rated issuers.
How Are Sovereign Bonds Denominated?
Sovereign bonds, which are debt securities issued by national governments to raise money, can be denominated in either the local currency or in a global currency such as the U.S. dollar or the euro.
Are Sovereign Bonds Risky?
As with any bond, the risk is judged by the likelihood that the issuer will default. Sovereign bonds are rated by the same agencies that rate corporate bonds to indicate their relative risk.
Sovereign bonds issued by countries with low ratings are experiencing economic troubles, political instability, or both. That makes them more likely to default on their debts.
Sovereign bonds issued by countries with high ratings are more stable and have a low risk of default.
The Bottom Line
Sovereign bonds are vital tools for national governments to secure funding for a range of needs, from infrastructure projects to debt repayment. The safety of investing in these bonds varies significantly based on the financial and political stability of the issuer. Investors need to assess the risk of default, which is higher in countries with economic instability or political turmoil, and lower in more stable nations. Consider the bond’s denomination and the issuing country’s credit rating when evaluating risk. For easier access, especially to foreign sovereign bonds, investors can explore ETFs and mutual funds specializing in government debts, which also offer diversification benefits.
