The Benefits of Bonds

The Benefits of Bonds in the Current Environment

1. Diversification

Bonds offer a low to negative correlation with other risk assets and this supports the importance of having bonds as a diversification instrument. Using Blackrock data as at 30 September 2021, the following AUD fixed income indices show a low to negative correlation to risk assets. For this period, the range of correlations for traditional fixed income ranges from 0.52 to -0.25 relative to traditional risk assets and from -0.12 to 1.00 relative to government bonds respectively.

2. Efficiency

The low risk profile of bonds allows for efficient returns per unit of risk. The table below shows the return/risk ratio for various fixed income indices and traditional risk assets for the trailing five years (all returns annualised). The return/risk ratio for the Bloomberg Barclays US Aggregate Bond Index is the most efficient allocation across the spectrum. Thus, while potential returns for bonds in the low yielding environment may not seem that appealing, investors should consider an allocation to bonds considering the low risk profile of bonds.

Currency Asset class Index Return Volatility Return/Risk
USD Equities S&P500 Index 15.2% 15.3% 0.99

3. Credit Quality

The average credit rating of bonds outstanding in the Australian corporate bond market is high by international standards. The Bloomberg AusBond Composite 0+ Yr Index has an average rating of AA+ equivalent versus the Bloomberg Global Aggregate Credit Total Return Index (Unhedged USD) of A equivalent respectively.

Those four notches of difference (between AA+ and A equivalent) in credit quality imply a significantly lower average cumulative default rates on Australian bonds versus international bonds.

The global default rate for investment-grade companies is only 0.02% and 2.4% for high-yield corporate bonds in the three years to December 2019 according to data from the S&P Annual Global Corporate Default and Rating Transition Study.

4. Risk Mitigation

Bonds suit investors who are in the retirement or deaccumulation stage in their investment life cycle. Many other traditional risk assets like equities as well as alternative assets like real estate and private credit cannot achieve the same drawdown risk mitigation. For example, having a portfolio that is comprised of 60% equities/40% bonds versus a portfolio of 100% equities can help avoid a situation like the recent COVID-19 sell-off in traditional risk assets.

Consider also that for the first three months of calendar year (CY) 2020 the S&P500 Index fell by an annual equivalent of ~60% compared to the Bloomberg Barclays US Aggregate Bond Index – which increased by an annual equivalent of ~13%. Thus, wholesale investors would have netted a handsome return during what was a very tumultuous period had they managed their equities/bond exposure well.

5. Income Generation

Bonds can still generate good returns. Over the last ten years, the Bloomberg Barclays US Aggregate Bond Index has generated a cumulative total return of 34.66%, with most of this comprised from the income/coupon component (30.07%).

Wholesale investors like income/coupon generation and bonds continue to provide good income/coupon prospects regardless of the low yielding environment and associated equity dividend yields.
