No corporate bonds? Time to reconsider

Damien Wood, Principal, Spectrum Asset Management
2 November 2015

With some corporate bond yields currently beating those of bank deposits, it may be time to consider these asstes for your portfolio.

Australian superannuation investors have largely shunned corporate bonds. Post the GFC this was logical for many. Why invest in Australian corporate bonds when you could get the same yield for less risk and less hassle by sticking with Australian bank deposits? This rationale is changing, however. Low-risk short-dated corporate bond yields are now moving higher than those on deposits. Spectrum sees this as a return to “normal”. If sustained, as we expect it will be, corporate bonds may be part of the solution for those frustrated with current deposit rates.

Why the deposit premium?

The so called “deposit war” between banks appears to be either over or in a state of cease fire. This battle began during the GFC. At that time there was heightened sensitivity to bank vulnerability across the globe. When looking at Australian banks the key weakness was deemed to be too much funding dependence on foreign bond investors and not enough local deposits. “Encouraged” by regulators and credit rating agencies, the banks took steps to address this. In doing so they raised the relative level of bank deposit rates and so began the deposit war.

Chart 1 shows that post the GFC, the yield on one year bank deposits was largely the same as one could get on a 3 year “A” rated corporate bond. Deposits, however, had some other appeal. These were and currently are as follows:

  • Deposits up to $250,0001 carry a AAA-rated government guarantee,
  • Deposits over $250,000 have higher Aa2 credit ratings for the big four banks,
  • Deposits are shorter dated than the bonds being compared to, and
  • Deposits are relatively simple to invest in.

Investors accordingly voted with their wallets and kept their superannuation out of fixed income and in equities and bank deposits.

Spectrum believes the recent deposit war was a large reason why Australian pension or superannuation funds have far less exposure to fixed income than their peers around the world.

For Self-Managed Super Funds fixed income accounts for less than 1% of investments. Spectrum believes Australian self-driven investors did not shun fixed income as an investment class. They rationally used deposits as a substitute for the reasons noted above.

Why there is a cease fire in the deposit war?

Australian banks have succeeded in building deposits in recent years. As Chart 4 shows, deposits have grown from around 40% of banks’ balance sheets during the GFC to nearly 60% now.

The near 50% increase in deposits, in particular those with maturities in excess of 30 days, helped the banks to meet new liquidity regulations. Specifically they were required to have over 100% for their Liquidity Coverage Ratio (LCR) due by January 1 2015.

  LCR Date
Banks meet new liquidity regulation
ANZ 119% 31 March 2015
CBA 120% 30 June 2015
NAB 118% 31 March 2015
WBC 114% 31 March 2015


Return to normality

In Spectrum’s view bank lending markets are not sustainable when deposits give the same yield as highly rated short dated corporate bonds. The reason is simple. The most basic business of a commercial bank is lending to borrowers at greater yields than the bank borrows. And if highly rated companies borrow at the same rate as bank depositors the core bank business model does not work.

Pre GFC the yield difference between three-year A-rated corporate bonds and bank deposits was around 1.3%. This is not only typical of what happens in Australia but in most developed banking markets around the world. As the Chart 1 shows, the yield gap is beginning to emerge again towards this level. More importantly Spectrum believes the positive spread that short dated corporate bonds have over deposits is likely to be the norm for at least the medium term.

Is 1% extra a big deal?

It can be. The reason is yields on most investments have collapsed in recent years. An additional 1% per annum compounding over several years can make a large difference.

For example consider a bond fund that delivers a modest 3% per annum and compare this to a deposit that gives 2% per annum. The income difference over 10 years for $10,000 invested would be around $1250. Or, put another way, the bond fund would deliver an additional 57% in income.


Corporate bonds usually yield more than banks deposits. Some key drivers which stopped this happening post the GFC have eased. This improved relative yield outlook for corporate bonds may soon get the attention of superannuants. For a modest increase in credit risk investors can improve their returns notably for what may be only modest increase in risk. In the current era of low deposit yields this could just be what some investors are seeking.
