For multi-asset investors, bonds play a critical role in balancing a portfolio by providing both income and diversification. Here, we explore the importance of their contribution.
Government bonds have historically provided strong diversification benefits, especially during equity market stress. Bond and stock prices often do not move in tandem or even move in different directions (low or negative correlation). Therefore, bonds can act as a shock absorber, particularly over longer horizons.
The chart below clearly illustrates this point. For example, during the 2000–2002 period or the global financial crisis in 2008, bonds delivered strong returns while prices of the MSCI World stocks fell sharply. That counterbalance was less strong in 2018 and 2022 when interest rates were near-zero.
Yield is back
Fixed income offers meaningful returns as interest rates moved higher since 2022. Investors can earn attractive income from core government bonds without having to take on excessive risk.
To put the shift into context, UK 10-year gilts (government bonds) currently yield around 4.4%, compared with just 0.1% at their 2020 low. Higher yields not only mean more income today, but they also improve the return outlook for the years ahead – giving bonds a more meaningful role in portfolios than they’ve had for over a decade.
Inflation hedging potential
Inflation-linked bonds (‘linkers’) offer protection against unexpected inflation spikes. While not a perfect hedge, they remain one of the few asset classes that directly link payouts to CPI (Consumer Price Index) – a key measure of inflation. This makes them a valuable tool in a world where inflation surprises have become more frequent and volatile.
From a financial planning perspective, maintaining purchasing power is critical – especially for long-term investors or those relying on portfolio withdrawals for income. By helping to preserve real (inflation-adjusted) returns, linkers can support more reliable cash flow planning and reduce the risk of eroding wealth over time. They can be particularly useful for retirees or anyone with future liabilities sensitive to rising costs.
Predictable payoffs
Unlike equities, where returns are driven by earnings and valuation changes, the yield on a bond is a strong indicator of its total return, therefore allowing for more predictable outcomes. The bond yield measures the annual return as a percentage of the bond’s current market price.
In an environment where market volatility and uncertainty remain elevated, this predictability is particularly valuable. Bonds can serve as a foundation for building a more stable, income-generating portfolio. They allow for clearer cash flow projections and to fund spending needs in retirement. When paired with other diversified assets, they can enhance both return potential and risk management.
Liquidity
Government bonds are highly liquid, meaning you can buy and sell them with ease and without having a large impact on the price. This is a useful feature when investors are suddenly required to sell their assets following some unexpected change in circumstance. Other cash flow generating assets are often less liquid. An example of this is property which is difficult and time-consuming to sell.
Investable universe
There are thousands of bonds available to investors, spread across countries, currencies, sectors, maturities and credit quality. This means there is no shortage of diversification opportunity within the asset class. In fact, the Global Aggregate Bond Index has around 20,000 constituents of better-quality (“investment grade”) government and corporate bonds.
Tax benefits
UK gilts offer benefits for UK investors in that they are free from Capital Gains Tax (CGT). This makes them an attractive alternative to cash, where interest is typically subject to income tax. By purchasing a low-coupon gilt today, investors can generate most of their return through capital gains rather than income – offering a more tax-efficient investment strategy.
When gilts are held to maturity, you can be confident in the cash flows and principal at maturity. This creates the opportunity for more detailed cash flow planning than might be the case with other assets.
Not just the safe asset
When thinking of bonds, many investors have the tendency to think of government debt. However, by lending your money to companies rather than governments, you can pick up an extra yield (known as a credit spread) to compensate you for this risk.
Bonds are given ratings based on their perceived risk. Investing in higher risk bonds offers a higher spread and hence higher return potential. Companies can of course default on their debt (when they are not able to pay you back) which stressed the importance of diversification. Investors typically choose to access corporate bonds through managed funds rather than directly to spread this risk across different companies and sectors.
The bottom line
In today’s more normalised yield environment, bonds offer a richer toolkit: defence, income, potential inflation hedging, and tactical opportunities. For multi-asset investors who want to elevate the power of diversification, as well as security and predictability, this makes them a valuable asset allocation tool.
Today’s bond markets offer more than just stability – they provide income, inflation protection, and a clearer path to predictable returns. Whether you’re preparing for retirement, managing long-term goals, or just seeking greater peace of mind, now could be a smart time to reassess how bonds fit into your portfolio.
