There has been a strong technical tailwind to high yield bonds for the past year, as a shrinking market has met robust demand. The result has been a downward squeeze on spreads (the additional yield that a corporate bond offers over a government bond of the same maturity). At first glance this all seems positive but there are two sides to every coin. For high yield investors it is worth being aware of both the benefits and the risks.

A shrinking market

As Figure 1 shows, the last couple of years have seen the global high yield bond market shrink in size, with the par value outstanding falling by 18% since the end of 2021. The positive for high yield bond investors is that a smaller market creates scarcity value, although at over US$2 trillion in size, with more than 3,200 bonds from 1,500 issuers, the global high yield bond market remains a diverse market.¹

Ironically, the market has been a victim of the success of its constituents, with some high-profile names moving from high yield to investment grade status (so-called rising stars) and exiting the high yield index. Last year, Ford, the auto company, was the biggest borrower to make the move. In the first half of 2024, rising stars so far have included Rolls Royce, the British aerospace business, Enlink Midstream, a US processor and distributor of oil and natural gas, First Energy, the US electricity utility, and Cellnex, the Spanish telecoms group. The broad sector spread has been encouraging, reflecting both a recovery to a more normal operating environment following pandemic-induced instability and stronger earnings helping to drive declines in leverage.

That is not to say the movement is all one way. Fallen angels (companies moving down from investment grade and entering the high yield index) this year include Hudson Pacific Properties, a US based office property group, Travis Perkins, the UK builders’ merchant, Alstria Office REIT, the German office real estate investment trust, and Elo, a French holding company straddling retail, real estate, and payments.

Taken together, however, the face value of rising stars has eclipsed fallen angels, contributing to a shrinking market. This is clear in Figure 2, which relates to the European high yield market. Since the start of 2022 there has been plenty of new supply, but this has been offset by maturing bonds and bonds being bought back ahead of maturity through a call/tender offer. Defaults are another (clearly unwelcome) way that high yield bonds can leave the index, although so far defaults have remained fairly contained.

Private credit cannibalisation
Both in the US and Europe there has also been some cannibalisation of the debt markets by private credit which has displaced debt that might have been issued in the public capital markets. This phenomenon is evident in both the US and Europe. Barclays noted that private credit makes up around 21% of leveraged finance in the US and 34% in Europe, compared with around 40% by high yield bonds and the remainder in both markets from leveraged loans.² It is in the area of leveraged buyouts that private credit has potentially displaced high yield bonds the most, given a drop in syndicated high yield deals and a rise in direct lending.

We see private and public debt markets co-existing because corporate borrowers value the useful competition this creates regarding lending terms and rates. While this may contribute to slightly lower yields for investors on high yield bonds there is likely an offsetting benefit – private credit may play a crucial role in suppressing default rates by stepping in to provide funding under more restrictive credit conditions.

Does size matter?

Optically, it seems better when a market is growing as it is suggestive of investor appetite and liquidity. But a contraction or flatlining of the market size can actually be good for investors.

It can be symptomatic of companies prioritising debt reduction, which tends to happen when the cost of capital has risen. It will be interesting to see whether the relative tightness in spreads leads to a change in corporate behaviour and a pick-up in less credit-friendly activities such as debt fuelled takeovers and share buybacks.

We have already mentioned rising stars outpacing fallen angels as credit quality at issuers improves, although the pace has been decelerating. Here we need to be mindful that most rising stars move up from a BB rating (the highest quality high yield cohort) into BBB (the lowest quality investment grade cohort). This can have the effect of shrinking the proportion of issuers rated BB if there are not corresponding upward ratings moves further down the rating spectrum.

Looking at the global index in Figure 3, there was a contraction in the proportion of BB rated bonds in 2022-23 but there has been an improvement since the start of 2024. What has been noticeable is a decline in the size of the B rated cohort which has been hollowed in both directions recently as some issuers are upgraded and others drop into the CCC or lower cohort. An example of the latter in 2024 was the downgrade of Altice, the France-based telecoms group, which is suffering from negative free cash flow and concerns that the company may seek distressed exchanges to help lower its debt to a more sustainable level.

Mindful of spreads

All told, we think the technical outlook for the asset class remains favourable. Outside of a recession we think investors will continue to see attractions in the yields on offer in high yield bonds, particularly if interest rates come down. With many high yield bonds also trading below their par value, there is a useful pull to par in bond prices as bonds get closer to maturity. We are mindful, however, that credit spreads within high yield are relatively tight so we need to keep a careful lookout for events that could upset the corporate backdrop, such as geopolitics or negative developments in the economic data. That said, the reasonably supportive corporate backdrop of moderate economic growth and robust earnings we believe justifies spreads being towards their tight levels, particularly among the better quality issuers within the BB and B cohorts.

The lagged impact of earlier monetary tightening means idiosyncratic risk is building among companies, however, necessitating careful analysis of credit fundamentals. Bank of America noted that among US high yield bonds since 2022, the higher quality borrowers had refinanced around 30-35% of their debt while the bottom 20% by credit quality had managed to refinance only 15% of their debt.³

This is just one of the reasons why we are more cautious towards the lower quality end of high yield. There are selective opportunities among the lower rated bonds but we want to avoid being caught in distressed bonds. We therefore see the remainder of 2024 as a time to favour active investing, seeking to squeeze out the value among the attractive yields on offer in the asset class.

IMPORTANT INFORMATION

Fixed income securities are subject to interest rate, inflation, credit and default risk. The bond market is volatile. As interest rates rise, bond prices usually fall, and vice versa. The return of principal is not guaranteed, and prices may decline if an issuer fails to make timely payments or its credit strength weakens.

High yield or “junk” bonds involve a greater risk of default and price volatility and can experience sudden and sharp price swings.
