Portfolio Composition

BSUB aims to track the performance of the Solactive Australian Major Bank Subordinated FRN index before fees and expenses. The fund's holdings are concentrated, comprising just 13 companies in total, with the top ten holdings accounting for 82.59 percent of the portfolio and the remaining 17.40 percent spread across other issues. The named holdings include subordinated notes from ANZ Group Holdings, Australia and New Zealand Banking Group, Westpac Banking Corp, National Australia Bank and Commonwealth Bank of Australia, with individual weightings ranging from 7.43 percent to 9.79 percent. Geographic exposure sits at 100 percent Australia, reflecting the fund's narrow focus on the domestic major bank sector.

Distribution History

BSUB declared an interim distribution of $0.117 per unit, equating to an annual Yield of 4.83 percent. The ex-date was 1 September 2026, with a Record Date of 2 September and a payment date of 16 September 2026. Reviewing the recent distribution sequence, the fund paid $0.103 in May, $0.099 in June, $0.110 in July, $0.115 in August and $0.117 in September, showing an overall increase across the period despite a dip between May and June.

Asset Allocation and Category Context

The fund allocates 100 percent of its portfolio to bonds, with no exposure to cash, stock or other asset classes reported. This full allocation to subordinated bank debt reflects the fund's specific mandate, distinguishing it from broader diversified credit funds that spread exposure across multiple sectors and issuer types.

BSUB sits within the Unconstrained Fixed Income category, which covers funds with broad scope to build portfolios without close reference to traditional bond indices. Funds in this category can include government bonds, corporate debt, securitised bonds, sub-investment grade debt, emerging market debt, private debt and hybrid securities, with aggregate Interest Rate and credit risk that can vary substantially over time relative to standard market benchmarks.

Who Should Watch BSUB

Analysts and investors following the Australian banking sector's capital structure, including how subordinated debt instruments are priced relative to senior bank debt, may find BSUB relevant to their research. Those tracking floating-rate income products, or comparing BSUB against related Betashares products such as QPON, which holds senior rather than subordinated bank debt, could also monitor this fund's ongoing distribution and pricing trends.

Conclusion

BSUB's structure reflects a narrowly targeted approach to fixed income investing, concentrating exposure on subordinated debt issued by a small group of major Australian banks. Recent data shows a distribution trend that has moved higher over the past several months, alongside a unit price that has remained within a relatively tight 52-week range, reflecting the more contained Volatility typically associated with bank-issued floating-rate securities.
