Understanding Bonds: Basics, Benefits, and Risks

How to invest in bonds

Bonds may play a role in portfolio diversification and income planning, but they still involve risks such as interest-rate risk, credit risk, inflation risk and liquidity risk. Here is a short summary of common considerations when investing in bonds.

Understand your investment goals

Before investing in bonds, investors usually review their financial goals, income needs, risk tolerance and investment horizon. These factors may help determine whether a bond, bond fund or other investment product is appropriate for the portfolio.

Compare bond types against objectives and risk

Different bond types carry different credit, interest-rate, liquidity and tax risks:

• Government bonds are often used for lower-credit-risk exposure where the issuer is highly rated, although risk varies by country, maturity and currency.
• Corporate bonds may offer higher yields than highly rated government bonds, but they carry company-specific credit risk.
• Municipal bonds may provide tax advantages in some jurisdictions, but rules depend on the country, issuer and investor.
• Zero-coupon bonds may appeal to investors seeking a future lump-sum payment, but prices can be sensitive to interest-rate changes and there is no periodic income.

Consider bond funds or ETFs

If you prefer not to invest in individual bonds, bond funds or exchange-traded funds (ETFs) may provide exposure to a diversified basket of bonds and professional management. These funds can reduce reliance on a single issuer, but they still carry interest-rate, credit, liquidity and market risk.

Understand bond pricing and yields

Bond prices and yields are inversely related: when market interest rates rise, existing bond prices usually fall, and when market interest rates fall, existing bond prices usually rise. Understanding this relationship is important, especially for investors who may sell bonds before maturity.

Purchase bonds through a broker or directly

Investors may buy bonds through a brokerage account, although the range of available bonds depends on the platform, market and investor eligibility. In some countries, investors may also be able to buy certain government bonds directly through official government platforms.

Monitor your investments

Periodic reviews may help investors check whether bond holdings still match their financial goals, risk tolerance and income needs. Interest-rate movements, issuer credit quality and changes in personal circumstances can all affect whether the holding remains appropriate.

Consider laddering your bonds

Bond laddering involves buying bonds with varying maturity dates. This may help spread reinvestment timing and reduce reliance on a single interest-rate environment, although it does not remove interest-rate, credit or liquidity risk. As bonds in the ladder mature, proceeds may be reinvested, but future yields are uncertain.

Advantages of investing in bonds

Bonds may offer potential benefits in a diversified portfolio, but those benefits depend on the issuer, maturity, currency, credit quality and market conditions.

Common potential benefits include:

1. Steady income stream

Many bonds pay interest at regular intervals, usually annually or semi-annually, which may provide a more regular cash flow than some other investments. However, interest payments depend on the issuer meeting its obligations, and income can vary across bond types and bond funds.

2. Capital preservation

For investors with lower risk tolerance, some bonds may be considered as part of a diversified portfolio, depending on the issuer, maturity, currency and objectives. Bonds are often less volatile than equities, particularly highly rated government and corporate bonds, but they are not risk-free. When an individual bond is held to maturity, the face value is due to be repaid if the issuer does not default, but inflation, taxes, fees and currency movements can still affect real returns.

3. Diversification

Bonds may add diversification to an investment portfolio, because they can behave differently from equities in some market conditions. This may reduce overall volatility in some portfolios, although correlations can change and bonds can also fall in value.

4. Tax advantages

Certain types of bonds may offer tax benefits in specific jurisdictions. For example, some municipal bonds in the US may provide interest that is exempt from federal income tax and, in some cases, state or local taxes. Tax treatment depends on the bond, investor and jurisdiction.

5. Lower volatility

Compared with equities, many bonds have historically shown lower price volatility, although this varies by issuer, maturity, credit quality and interest-rate conditions. Bond prices can still move sharply, especially for long-duration or lower-quality bonds.

6. More predictable returns

Because many bonds pay fixed interest and have a set maturity date, returns may be more predictable than some other investments if the bond is held to maturity and the issuer meets its obligations. Realised returns can still vary if the bond is sold before maturity, default occurs, inflation reduces purchasing power, or costs, taxes or currency movements apply.

7. Potential for capital gains

While bonds are typically held for income, they may also generate capital gains or losses if sold before maturity. If market interest rates decline after a bond is purchased, its price may rise, although any realised gain depends on sale price, costs, taxes and market liquidity.

Risks of investing in bonds

While high-quality bonds are often viewed as less volatile than stocks, they are not risk-free.

Understanding these risks may help investors assess whether bonds fit their objectives, risk tolerance and investment horizon.

Interest rate risk

One important risk associated with bonds is interest rate risk. When interest rates rise, the market value of existing bonds typically falls because newer bonds may offer higher returns. This can be particularly concerning for investors who may need to sell their bonds before maturity.

Credit/default risk

Bonds are subject to the issuer's credit risk. If the issuer's financial situation deteriorates, it may fail to make interest payments or repay the principal at maturity, leading to a default. Corporate bonds, especially high-yield (junk) bonds, are more susceptible to this risk than government bonds.

Inflation risk

Inflation erodes the purchasing power of a bond's future interest payments and principal repayment. If inflation rises significantly, the fixed payments from bonds may not keep up, reducing the real value of returns.

Liquidity risk

Some bonds, particularly those from smaller issuers or with lower credit ratings, may be difficult to sell quickly without reducing the price. This lack of liquidity can be a problem if an investor needs to access cash quickly.

Reinvestment risk

Reinvestment risk occurs when a bond matures or is called, and the investor must reinvest the proceeds at a lower interest rate. This is particularly relevant in a declining interest rate environment.

Call risk

Certain bonds have a call feature that allows the issuer to repay the bond before maturity, usually when interest rates decline. This can be disadvantageous to investors, as it often forces them to reinvest at lower rates.

Market risk

Although bonds are generally less volatile than stocks, they can still fluctuate in value due to broader market conditions, including changes in economic outlook, political events, or shifts in investor sentiment. This means bonds still carry risk, even when they are considered lower volatility than equities.

Conclusion: Bonds as a part of your investment strategy

Bonds may play a role in a diversified investment strategy by providing income, different risk characteristics from equities and exposure to issuers such as governments or companies.

However, they are not risk-free: prices can fall, issuers can default, inflation can reduce real returns and liquidity can vary. Periodic reviews may help you assess whether bond holdings still match your goals, income needs, time horizon and risk tolerance.
