The Australian ASX listed hybrid market generally trades at a premium versus similar securities in the institutional market, meaning listed assets generally produce a lower yield than comparable assets in the over-the-counter (OTC) market. However, we are currently seeing significant yield discrepancies beyond what is considered standard.
One of the reasons behind the sustained yield differential is that generally retail investors in Australia are only able access corporate bonds directly through ASX listed securities. However, the ASX listed bond market is relatively small, representing only 7% of the total corporate bond market.
In the institutional market, established relationships exist between the trading margin of bank bonds with different levels of seniority. The 3 main forms of bank bonds and their rank within the bank capital structure from highest to lowest in terms of security are Senior, Tier 2 Subordinated and Tier 1.
Senior debt generally typically trades in a range around 45% of the credit spread or trading margin (note that credit spreads are the major contributor to the yield of a corporate bond) of Tier 2 subordinated bank bonds with a similar maturity, while Tier 2 subordinated bank bonds will trade in a range around a margin of roughly 65% of Tier 1 bonds. So, if the trading margin of a 5 year, senior bank bond is 1%, then Tier 2 subordinated bank bond margins should trade in a range around 2.2% and Tier 1 bonds should trade in a range around a margin of 3.7%.
This relationship is based on the relative risks of the different bonds – senior debt ranks higher in the capital stack versus Tier 2 subordinated debt which in turn ranks higher than Tier 1. Tier 1 debt also has equity like features, which is an additional reason for it to trade at a level higher than Tier 2 subordinated debt.
While the relationship between the three structures has been generally consistent over time, it can get stretched during periods of volatility. For example, during the market stress of March 2020, Tier 2 subordinated bank trading margins hit a wide of around 4% while Tier 1 trading margins were at least twice that level at 8%.
Turning to a more recent example, when the recent CBAPK bond (a listed hybrid Tier 1 Bond) was issued in March, the trading margin of 2.6% appeared to be about the right level versus where Tier 2 subordinated bank paper was trading at the time. However, since the issuance of the CBAPKs, the institutional credit markets have sold off in line with other risk assets.
As a result, the Tier 2 subordinated bank market has moved roughly 0.5% wider, with 5-year securities trading at a margin of around 2.1%. Based on historical comparisons, this suggest that the CBAPKs should be priced at a trading margin of roughly 3.4%. However not only have the CBAPK’s not traded wider, they’ve tightened; with the current price of $101 indicating a trading margin of 2.56%. If the CBAPKs moved to a spread of 3.4% in line the historical level versus Tier 2, its price would fall to 96.7; a 4.5% fall from current levels. This valuation discrepancy is further demonstrated when making a comparison with the NAB over-the-counter Tier 1 bond with a Jul 2025 call date (4 years less than CBAPK) that is trading at a margin of roughly 3.15%.
While there are entrenched supply/demand dynamics within the ASX listed hybrid market that result in it consistently providing a lower yield versus an over-the-counter comparable, rarely can they ignore the broader market activity completely for a sustained period. If the market continues to move wider it would be likely that the CBAPKs, and any other listed hybrids bucking the trend, would soon catch up.
