The case for investing in global credit

Global credit can be a useful diversifying asset class for Australian investors. It can offer higher income than cash, with less risk than shares, while bringing diversification benefits that can reduce overall portfolio risk.

The long-term performance of different asset classes' historical risk and return trade-off is shown in Chart 1. Global credit sectors have an intermediate risk-return profile through different investment cycles.

Optimising asset allocation is particularly important in the current environment, because forward-looking asset class return profiles are likely to differ from the past. Government bond yields are at record lows, while share markets globally are reaching peaks.

Chart 2 shows how global credit sectors are producing higher yields compared to cash and government bonds.

Importantly, when allocating a portfolio across cash, fixed interest and equities, adding global credit has historically improved returns for a given level of risk, because global credit can perform well at different times to share, fixed income and other asset classes.

There are five key benefits of adding global credit investments:


Corporate bonds, loans and high-yield securities tend to pay investors regular coupons, with a higher yield than cash or fixed interest. A diversified portfolio of such coupon-paying instruments allows for the smoothing out of all those cashflows, which can be paid out as regular, high-yielding income (i.e., through monthly global credit fund distributions).


Credit investors benefit from having priority of payment above equity investors for payment of coupons and repayment of principal. Senior credit investors rank ahead of hybrid and subordinated debt investors. A credit investor's ranking in the company's capital structure is a key determinant of their recovery of investment if a company gets into trouble, and their certainty of receiving ongoing distributions.

In addition to seniority, some credit investments also provide investors with the benefit of security over specific assets of the borrower, providing further protection to the investor. This normally takes the form of a mortgage over property and other realisable assets. These factors mean the capital value of credit investments has been more resilient than equities.


Global credit is a large and deep market and significantly larger than global share markets. It has many different investor types, including asset managers, banks, insurance companies and pension funds. This diversity of investors means credit investments are traded between buyers and sellers even in difficult times.

Global credit has been a more resilient asset class than equities, recovering far faster than equities after the Global Financial Crisis (GFC). Global credit is regarded as intermediate risk with an investment horizon of three to five years.

Global credit allows Australian investors to diversify away from Australian shares and achieve a broader spread of exposures across issuers and economic/geographic areas. Industry diversification is particularly important, because corporate failures may occur in clusters - the technology crash in the early 2000s, or financial institutions during the GFC, for example.

Industry diversification is difficult to achieve in the Australian market. Australia is a small economy with a heavy concentration to financials and miners. Far greater diversification is available by investing in global asset classes.

There are many types of credit investments within the global credit asset class, including investment-grade bonds, global syndicated loans, convertible bonds, high-yield bonds, securitised debt, capital securities, and fixed-rate and floating-rate securities. They offer different types of credit risk and return opportunities.

Like all investments, there are risks to consider. The key one is credit risk, where a company fails to repay coupons or principal in full and on time. Credit risk can be best managed and mitigated through careful investment analysis and security selection, thorough review of creditor protections in any security (i.e., seniority, security), a focus on rated, liquid investments, and significant diversification.

Accessing global credit with sufficient diversity and liquidity

Retail investors cannot effectively access global credit investments directly because:

There is a lack of credit assets domestically. Banks dominate lending in Australia, which limits the issuance of credit in public capital markets as in the US and Europe;

Credit markets are largely institutional. Credit securities are typically only sold to wholesale investors and/or have large minimum investment sizes ($500,000 plus). The small number of individual credit securities made available directly to the retail market in Australia are often of "non-institutional quality", being subordinated, unrated and without a liquid, traded market; and 

Credit investing requires considerably more diversity than equity portfolios. Diversity is more important in credit portfolios than in equity portfolios but less recognised. A credit portfolio with 20 to 50 securities is not diversified enough to reap the full benefits of diversification. The diversity required to create a robust credit portfolio is simply not possible to replicate with a small portfolio (for context, Bentham's credit funds typically have between 150 and 600 unique issuers in each).

This is why global credit has historically been a more institutional market. Even the larger institutional investors, such as industry superannuation funds in Australia, will typically invest in global credit via managed portfolios, not through selecting a small number of individual bonds.
