Bond Investing for International Investors: A Practical Guide

Fixed income — bonds — has had a turbulent period. The sharp rise in interest rates globally through 2022–2023, and their subsequent partial decline, produced the worst returns for government bonds in generations. Investors who had held long-duration bonds for income found themselves sitting on significant capital losses. Yet bonds remain an essential component of a diversified portfolio, and the higher yield environment since 2022 has made the asset class considerably more attractive than the near-zero rates of the preceding decade.

For internationally mobile investors, bonds offer additional dimensions: access to sovereign and corporate credit in multiple currencies, exposure to different interest rate cycles, and in some cases meaningful tax advantages. This guide covers the essentials.

What Is a Bond?

A bond is a loan made by the investor to an issuer — a government, a company, or a supranational body — in exchange for:

• Regular interest payments (the coupon) at a fixed or variable rate
• Return of the principal (face value) at maturity

Bonds are issued at a face value (typically £100 or $1,000), which is the amount repaid at maturity. They trade in secondary markets, and their prices move inversely to interest rates: when interest rates rise, existing bonds with lower coupons become less attractive, so their prices fall. When rates fall, existing bonds with higher coupons become more attractive, so their prices rise.

This inverse relationship between price and yield is the foundational principle of bond investing. It is also the source of most of the capital loss that bond investors suffered in 2022.

Key Concepts

Yield to maturity (YTM). The total return an investor will earn if they hold a bond to maturity, assuming all coupon payments are received and reinvested. YTM is the standard measure for comparing bonds with different prices and coupons.

Duration. A measure of a bond's sensitivity to interest rate changes. A bond with a duration of 10 years will fall by approximately 10% in price if interest rates rise by 1%. Longer-dated bonds (those with distant maturities) have higher duration and are therefore more sensitive to rate changes.

Credit spread. The additional yield a corporate or emerging market bond offers over a risk-free government bond of the same maturity. A corporate bond might offer a yield of 6% when the equivalent-maturity government bond yields 4% — the credit spread is 2%, or 200 basis points. Credit spreads widen when credit conditions deteriorate (representing higher compensation for default risk) and narrow when conditions improve.

Investment grade vs high yield. Bonds rated BBB- and above (by S&P and Fitch) or Baa3 (by Moody's) are classified as "investment grade" — lower default risk, lower yield. Bonds below these thresholds are "high yield" (or "junk") — higher default risk, higher yield. The distinction affects both risk and the availability of institutional buyers.

Government Bonds

Government bonds (gilts in the UK, Treasuries in the US, Bunds in Germany) are generally regarded as risk-free in the sense that the issuing government can, in extremis, print money to repay them. In practice, "risk-free" means:

• Very low probability of default (for developed market governments)
• High liquidity — government bond markets are among the most liquid in the world
• Interest rate risk — as discussed, duration risk is the primary risk for government bonds

UK gilts are issued by HM Treasury. Their yields reflect UK interest rate expectations, inflation expectations, and fiscal credibility. The 2022 "mini-budget" crisis demonstrated that even UK gilts are not entirely immune from political/fiscal risk — gilt yields spiked sharply, causing pension fund distress.

US Treasuries are the world's benchmark safe haven asset. Their liquidity is unmatched.

Emerging market sovereign bonds. Countries such as Turkey, Egypt, Argentina, South Africa, and Indonesia issue sovereign bonds — often in USD or euros as well as local currency. These offer significantly higher yields but carry genuine default risk (all of the above have defaulted or restructured debt at some point). For internationally mobile investors with exposure to particular regions, EM sovereign bonds can provide both income and economic exposure, but require careful credit assessment.

Corporate Bonds

Corporate bonds are issued by companies. Key distinctions:

Senior secured bonds are backed by specific assets and rank ahead of other creditors in a default. Senior unsecured bonds are not backed by assets but rank above subordinated debt. Subordinated/hybrid capital bonds rank below senior debt and above equity. They carry higher credit risk but offer higher yields.

Investment grade corporate bonds (e.g. bonds issued by Shell, Nestlé, or Apple) currently yield approximately 4.5–6% in sterling or euros as of 2026, depending on maturity. High-yield bonds of similar duration yield approximately 7–9%.

Liquidity is an important consideration in corporate bonds. Large-cap investment grade bonds from major issuers are relatively liquid; smaller issuers and high-yield bonds can be considerably less liquid, with wider bid-offer spreads.

Bond Funds vs Individual Bonds

Most private investors access bonds through funds rather than buying individual bonds directly:

Individual bonds. Direct purchase is possible but typically requires minimum investment sizes of £10,000–£50,000 per bond, and diversification across multiple bonds requires significant capital. Transaction costs (bid-offer spreads) can be material for smaller trades. The advantage is certainty of return: if you hold to maturity, you receive the coupon and face value as agreed.

Bond funds (OEIC / unit trust). Pooled funds managed by a fund manager, investing across many bonds. Minimum investment is typically £1,000–£5,000. Daily liquidity (usually). The trade-off: no "maturity date" and hence no guarantee of return — the fund's value fluctuates with the market.

ETFs. Bond ETFs trade on exchanges and track bond indices. Very low cost, daily liquidity, transparent composition. Most internationally mobile investors with access to major brokerage platforms can access a broad range of bond ETFs in multiple currencies and sectors.

Target maturity bond funds. A hybrid: pooled fund that holds bonds maturing in a specific year and distributes proceeds at maturity. Combines the diversification of a fund with the return certainty of direct bonds. Growing in popularity in Europe and the UK.

Building a Bond Allocation

For internationally mobile investors, the bond allocation strategy should consider:

Currency. Bonds denominated in your "consumption currency" (the currency in which you spend your money) carry less currency risk. Sterling bonds for UK-based retirees; euro bonds for Spain-based retirees; USD bonds may be appropriate for globally mobile investors. Unhedged foreign currency bonds add a layer of currency risk.

Duration. In a rising rate environment, shorter duration reduces capital loss risk. In a falling rate environment, longer duration amplifies capital gains. Matching duration to your investment horizon reduces reinvestment risk.

Credit quality. Investment grade for stable income and capital preservation; limited high yield for enhanced yield with understood risk; avoid concentrated exposure to single issuers.

Geographic diversification. A globally diversified bond portfolio (UK gilts, US Treasuries, European investment grade corporates, with selective EM exposure) reduces concentration risk.

Tax Treatment for Bond Investors

UK tax residents. Interest income from bonds is taxable as income. Gilts and most UK corporate bonds can be held in ISAs (where interest is tax-free). Capital gains on gilts and qualifying corporate bonds are exempt from CGT. Investment in an offshore bond wrapper can defer UK income tax.

Non-residents. UK non-residents are generally not subject to UK income tax on interest from UK bonds. Gains on UK bonds are generally not subject to UK CGT for non-residents. The treatment in your country of residence depends on local tax law.

Accrued income scheme. When buying bonds in secondary markets, the purchaser typically pays for accrued interest — the interest that has built up since the last coupon date. HMRC's accrued income scheme requires this to be allocated correctly for tax purposes. Your broker should handle this, but be aware of it.
