The case for global high yield bonds

The current geopolitical tensions across the globe including Brexit, trade war fears, changing global allegiances driven by the Trump administration, and the recent US government shutdown, have caused a new level of disruption and noise. However, it is not all bad news as we begin to see pockets of improvement in the world economy.

Growth in the US is helping to sustain the global economy. Meanwhile, closer to home, Australians have been fortunate to experience stable employment growth and in general, corporate balance sheets are in good shape.

Investors face a challenging time when it comes to portfolio construction. After years of slow economic growth and low interest rates post-GFC, we have recently seen rates rise in the US, but investors should pay close attention to the risks taken in their portfolios to obtain the necessary income. Given the RBA cash rates is just 1.5%, sitting on cash is not a long-term solution for real sustainable income.

We believe fixed income can provide a more stable source of income given mandatory coupons, and global high yield corporate bonds represent an attractive asset class for investors searching for a diversified source of income.

As an asset class, global high yield bonds have historically been mired in confusion, so let's explore why it is worth considering them.

1. Global high yield bonds have evolved

Mention ‘high yield bonds’ and some investors will label them as ‘junk bonds’. This was an apt description in the 1980s, when small and speculative companies dominated the sector, but the market has matured dramatically since then.

The high yield market has now evolved into a financing mechanism widely used by companies with sound fundamentals looking to diversify their funding mix away from pure bank debt or shareholder equity. There are now more than 2,000 companies in the market, which has grown from less than US$200 billion in the 1980s to approximately US$2.8 trillion today. These include household names such as Netflix, Hertz, Fiat and Mattel, as well as numerous important players in the telecom and internet industries. All these companies have significant revenue and profit streams to service their high yield debt, and the label of 'junk bond' is no longer suitable for many of them.

2. Bond allocations need to be diversified

There are important fundamental principles in building an allocation to bonds. The allocation should lower risk and stabilise returns, offsetting the more volatile performance of equities and creating a steady income stream within the overall portfolio.

While traditional bonds provide diversification, they are more susceptible to interest rate fluctuations than global high yield bonds, which tend to be linked to corporate credit fundamentals. High yield bonds provide attractive returns and a lower risk profile than equities, making them an intermediary diversification tool within a traditional portfolio.

Global high yield bonds also offer geographic and sector diversification. While the US still dominates this market, companies from Europe and emerging markets across a wide array of industries issue high yield bonds. The market offers meaningful global exposure for investors looking for diversification, as shown in Figure 1.

US High Yield represents non-EM USD HY bonds. European High Yield represents European currency HY bonds. Data as of December 31, 2018.

3. Global high yield bonds generally perform strongly during periods of rising interest rates

While it is true that rising interest rates can cause falls in the value of bonds, the global high yield market has different characteristics to traditional long-dated government bonds and investment grade debt, with which investors are more familiar.

Historically, high yield bonds have performed well in rising interest rate environments, when the economy is doing well. There is usually growth in company earnings and overall improvement in corporate fundamentals. Consequently, credit risk for companies decreases, resulting in lower default rates.

For the past few years, central banks have set interest rates at historically low levels, but they have started to move back to what is considered normal or ‘neutral' settings. This recent trend is in stark contrast to the days when central banks were regularly hiking rates aggressively to slow economic growth and cap inflation. For corporates with fundamentally good balance sheets and trading prospects, the return to neutral interest rates has been a positive change.

High yield market fundamentals 

We believe the probability of a near-term recession is low and while volatility is likely to persist, valuations for high yield bonds compensate investors for the modest default risk. The operating performance of underlying issuers has been stable; revenue and EBITDA growth have improved as leverage has plateaued, and refinancing activity has significantly reduced the number of bonds maturing in the near term.

However, global high yield bond markets are susceptible to a variety of factors, including uncertainty around government disruptions such as aggressive rhetoric, trade policy and the overall regulatory environment. Below-average new issue supply of high yield bonds continues to be supportive, and we expect issuance to remain flat year-on-year during 2019.

An under-recognised asset class

In Australia, global high yield has traditionally been an under-represented asset class, and not one easily accessible to investors or SMSFs. By providing exposure to global credit markets, an allocation to global high yield bonds can provide diversification benefits to a domestically-biased portfolio and improve the overall risk profile.

Hi Warren,

We run an Australian focused private debt fund which incorporates ESG principles in each step of our investment process. If you would like to receive information on how a mandate governed by the Uniting Church Ethical and ESG Investment Policy could work then please email me directly.

I saw a presentation from NB a year or more ago, was impressed, came home and tried to work out how to invest through NB. I found the site but couldn't find anything that showed me how to invest. The link provided with this article goes to a page that says it is for wholesale investors. Like most people I am time poor, if I cannot find what I am looking for quickly, I go elsewhere. At some stage a month ago or so, I tried again and when I was again unsuccessful I decided to send a message on a feedback link I found where I just wanted to say "Ok but how do I give you money?", but something happened wit the feedback link where I could not send the message.
Seriously if someone from NB is reading this - you need to work on your website. Make it easier for someone to invest with a clear link on the front page that gets to the place where we send you money. I still do not know if you offer products for retail investors, whether they are listed or unlisted, what products are on offer, their past performance or how I invest.

Good paper making the case well.

In my personal investments I have an allocation to high yield bonds that has been part funded from what otherwise would be in investment grade corporate bonds and part funded from what would otherwise be in equities.

And if I could find a manager in the sector who had the capability of integrating the ethical and ESG investment policy of the Uniting Church in an AUD fund, I'd love to talk to them for an institutional investment. But high yield generally seems to be the laggard in ESG, or those that are decent don't have a good AUD product. Happy to be proven wrong .

Buffett's meeting takeaway: extreme caution

Warren Buffett's annual meeting of Berkshire Hathaway showed he has not been 'investing while others are fearful' during the crisis. lt's a reminder to take caution and preserve cash.

Welcome to Firstlinks Edition 356

Few investors are as influential as Warren Buffett, although for the moment, the market is ignoring his caution. The annual meeting of Berkshire Hathaway revealed Buffett did not use the heavy market falls in February to buy shares. Rather than 'buy when others are fearful', he was a net seller of US$6 billion for the quarter, disposing of all airline shares. Berkshire is sitting on US$137 billion in cash, suggesting he expects better buying opportunities to come.

The vibe of future returns: tell ‘em they’re dreamin’

It's the vibe, but not much else. Super balance calculations default to earnings rates of 7.5%, but that's in the past. Global experts suggest financial plans are now dreaming at this level.

Baseline outlook for economic recovery is too optimistic

We cannot throw our hands up in the air and say 'this time around, it's simply too hard'. Having no macro view is unhelpful, but many of the baseline scenarios are overly optimistic, says the former CEO of Westpac and now Chairman of Chi-X Australia.

Retiree spending patterns differ from most expectations

A study of actual spending habits shows retirees have a faster-than-expected drop-off in spending in later years, casting doubts on financial plans that assume increasing expenditure over time.

Welcome to Firstlinks Edition 357

There is a remarkable concentration similarity between the Australian and US stock markets that has delivered poor results for Australians and great results for Americans (and global investors). As the share prices of five Australian banks have tanked, the prices of five US technology companies have surged. Each group now represents 20% of their respective indexes, but the journey has been a disaster for many Australians.
