High-yield bonds: a timely opportunity for income-seeking investors?

While we still expect interest rates to fall over the next few years, the current conflict in the Middle East may delay this. But high-yield (HY) bonds still offer a good entry point for investors who are focused on income and long-term capital appreciation. 

Short duration strategies are less sensitive to interest-rates changes and have helped cushion portfolios from market swings. In the past few weeks, HY bonds have been outperforming their investment grade equivalents thanks to their higher levels of income and low duration, which makes them less sensitive to changes in rate expectations.

This combination of robust corporate fundamentals and unusually attractive yields makes HY bonds an appealing option in today’s turbulent world. For investors prepared to take a measured step up the risk spectrum, the asset class offers greater income potential than cash or gilts, while avoiding the full volatility of equities.

Why HY bonds stand out today

One of the key reasons investors are looking again at HY is simple: income is back. Global HY yields currently stand above 6.5%. Evidence shows that when yields begin from such elevated levels, subsequent returns tend to be strong. 

What makes this pattern so consistent? Unlike many asset classes, income – specifically coupon income – is the dominant driver of HY total returns. Over the past 20 years, coupon income has accounted for more than 100%* of total global HY returns. Other factors, such as credit spreads, have at times detracted from performance during volatile periods. 

This means HY could be well positioned to generate stable total returns even in turbulent markets. In contrast, money market funds and gilts, while stable, offer limited upside and may see their yields fall materially as soon as central banks begin easing policy.

* Because prices sometimes fall, the income ends up doing all the work, meaning more than 100% of the final return can come from coupons.

Comparing HY to equities: understanding the correlation

A common question UK retail investors ask is: how do HY bonds behave relative to equities? Because HY issuers are lower rated companies, their bonds do exhibit some correlation with equity markets, particularly during sharp risk off episodes. However, the relationship is far from linear.

HY typically experiences lower volatility than equities, largely because of its coupon driven return profile. Even when bond prices fall, income keeps accumulating, cushioning investors against short term swings. HY also has shorter duration, often around three to four years, which limits sensitivity to interest rate movements and helps reduce overall portfolio volatility.

In practice, HY tends to sit between equities and investment grade bonds on the risk-return spectrum, offering a more balanced way to capture corporate linked returns without full equity exposure.

A supportive backdrop: fundamentals and default risks

Strength in corporate fundamentals is also boosting confidence in today’s HY markets. Several indicators point to a more stable, healthier environment than in previous cycles: 

Together, these factors create a backdrop where investors can be compensated at attractive levels without a sharp rise in default risk.

Where investors can potentially add value: quality, income, diversification

While the HY market itself is attractive, certain approaches make the opportunity more compelling. Three principles stand out:

1. Focus on reliable coupon income

Given that coupon income drives long term HY returns, strategies that prioritise stable, high coupons – rather than trying to predict short term price moves – have historically delivered more consistent outcomes. Over two decades, coupon income has represented the majority of total returns, while spread-related volatility often detracted from performance. 

2. Combine developed and emerging market exposure

Global HY markets are not monolithic. Emerging market (EM) HY bonds, for example, often offer higher average yields as well as higher average credit quality than some developed market HY segments. Blending developed and EM exposure allows investors to access a broader range of opportunities and potentially enhance diversification, reducing reliance on any single corporate sector or region.

3. Maintain discipline on credit quality

HY spans a wide spectrum, from relatively stable BB rated bonds to riskier CCC issuers. Prioritising the higher quality end of the market, while still capturing elevated coupons, may help balance income and resilience by avoiding the default prone tail of the market.

HY versus low risk alternatives: what’s the trade off?

While cash and gilts are essential building blocks for many portfolios, their attractiveness depends heavily on interest rate levels. With markets expecting rate cuts, today’s high cash and gilt yields may prove temporary. 

HY bonds, in contrast, offer: 

For investors seeking to protect and grow their income as conditions evolve, this balance is increasingly worth considering.

What does this mean for investors?

High yield bonds are not risk free. But today’s unusually attractive starting yields, combined with solid corporate fundamentals and historically low default expectations, create one of the most favourable entry points in years.

For income focused investors looking beyond cash and gilts – and for those who want exposure to corporate credit without the full volatility of equities – HY may offer a compelling middle ground. Approaches that emphasise stable coupon income, global diversification and disciplined credit selection remain well suited to today’s landscape.
