What are bonds and are they preferable to investing in stocks?

Most people reading Stocks Down Under are interested in stocks because of their higher‑growth potential relative to bonds. Even so, we think even investors who don’t own bonds should still understand them.

The last four years have shown that bonds and equities can behave in unexpected ways, sometimes moving together, sometimes diverging sharply, and often revealing shifts in investor sentiment before equities do. With interest rates still elevated compared to the pre‑2022 era, and with global bond markets attracting renewed inflows after years of volatility, it is worth revisiting what bonds are, how they work, and how they fit into a modern portfolio.

What are bonds?

Bonds are debt securities issued by governments, municipalities, supranational bodies, or corporations to raise capital. When you buy a bond, you are lending money to the issuer. In return, you receive periodic interest payments (known as coupon payments) and the return of the bond’s face value (the principal) at maturity. The timing, interest rate, and structure vary from security to security.

Bonds are often referred to as fixed‑income securities because many of them pay a fixed interest rate. However, the fixed‑income universe in 2026 is far broader than it was a decade ago. Investors can still invest in fixed-rate bonds but can also choose from floating‑rate notes (which adjust with benchmark interest rates), inflation‑linked bonds, zero‑coupon bonds (which pay no periodic interest but are issued at a discount) or even callable or convertible bonds, which include optionality features.

The return on a bond is commonly measured as a percentage of its current price, known as the yield. Yields move inversely to prices. When interest rates rise, existing bonds fall in value because their fixed coupons become less attractive. When rates fall, existing bonds rise.

In 2026, this dynamic remains front‑of‑mind for investors. After the rapid rate hikes of 2022–2023 and the slower, more cautious adjustments since, bond markets have repriced dramatically. Yields are still well above the levels seen in the 2010s, which means bonds now offer income levels that were unthinkable only a few years ago.

Bonds can be purchased directly from issuers (such as governments during new issuance) or on secondary markets through exchanges and brokers. Corporate bonds, in particular, are widely traded and priced continuously.

Should I invest in bonds or stocks?

The answer depends on your goals, but the short version remains the same in 2026 as it has been for decades: bonds suit investors who prioritise stability and income, while stocks suit those who prioritise growth and can tolerate volatility. Many investors hold both.

The most important structural difference is that bondholders sit above shareholders in the capital structure. If a company goes bankrupt, bondholders have a higher claim on the company’s assets than shareholders. This does not guarantee recovery—creditors of Bonza, for example, learned that the hard way—but it does mean bonds are generally safer than equities.

However, “safer” does not mean “risk‑free”. Bond values fluctuate with interest rate movements, inflation expectations, credit risk (the issuer’s ability to repay), liquidity conditions, and market sentiment just to name a few.

In 2026, credit spreads have widened in some sectors as refinancing costs rise, and investors are paying closer attention to balance sheets than they did during the ultra‑low‑rate era.

Bonds are the safer, but more boring, option

Setting aside bankruptcy risk, several traits make bonds more suitable for risk‑averse investors and less suitable for those seeking high returns.
Bonds provide predictable income, which is valuable in a world where cash rates may fall from their peaks but remain structurally higher than the pre‑COVID decade. Government bonds, in particular, fluctuate far less than equities and are often used as a stabiliser in diversified portfolios.

If held to maturity, most high‑quality bonds return their face value, which gives them a natural anchor that equities do not have. This is why retirees, income‑focused investors, and institutions with fixed liabilities (such as insurers) rely heavily on bonds.

But the trade‑off is clear. Unlike stocks, which can appreciate significantly over time, bonds offer limited capital growth. You do not share in the company’s profits. You do not benefit from rising earnings. You simply receive the promised interest and principal.

In 2026, this trade‑off is more balanced than it was in the 2010s. With yields materially higher, bonds now offer meaningful income again. But equities still offer the superior long‑term growth potential.

Is there any correlation between bonds and stocks?

This is where things get interesting. The relationship between bonds and equities has changed dramatically since 2022.

For most of the post‑GFC era, stocks and bonds were negatively correlated. When equities fell, bonds often rose, providing a natural hedge. But when inflation surged in 2022 and central banks responded with aggressive rate hikes, the correlation flipped. Both asset classes fell together because both were being discounted at higher interest rates.

Morningstar data showed that correlation between stocks and bonds rose to 0.64 during the 2022–2023 rate spike, compared with –0.24 between 2009 and early 2022.

In 2026, the correlation has moderated but remains higher than the long‑term average. This is for three reasons, including that inflation is still above central bank targets in several economies, rate expectations remain volatile and markets are more sensitive to macroeconomic data than they were in the low‑rate era.

This imperfect and shifting correlation is precisely why diversification remains essential. Bonds still behave differently from equities over the long run, but the short‑term relationship can vary depending on the macro environment.

What has changed in 2026?

We last wrote this article in 2024. Several developments since then have reshaped the bond landscape. The first is that even with central banks signalling eventual rate cuts, the era of near‑zero rates is over. Investors can now earn meaningful income from government and investment‑grade corporate bonds without taking excessive risk.

Secondly, low‑cost ETFs have made it easier for retail investors to access diversified bond exposure. Flows into fixed‑income ETFs have surged since late 2023 as investors sought income and stability.

Third, companies that thrived in a low‑rate world now face higher refinancing costs. Investors are paying closer attention to leverage, cashflow, and maturity profiles. And fourth, duration risk is back in focus. Long‑duration bonds were hit hardest during the 2022–2023 rate shock. In 2026, investors are more conscious of how sensitive their portfolios are to interest rate movements.

Conclusion

In summary, bonds and stocks serve different purposes in an investment portfolio. Bonds offer income, capital preservation, and lower volatility. Stocks offer growth potential, dividends, and higher risk.

The choice between them depends on your objectives, risk tolerance, and time horizon. There is nothing stopping you from holding both, and indeed, most investors do. The events of the past four years have reinforced the value of diversification and the importance of understanding how different asset classes behave under different macro conditions.

In 2026, bonds are no longer the forgotten asset class they were during the ultra‑low‑rate era. They offer real income, real defensive value, and real insight into market sentiment. Whether you are a growth investor, an income investor, or somewhere in between, understanding bonds is now essential.
