Hybrid securities for retirees: tax treatment, conversion events, and the APRA phase-out

For Australian self-funded retirees who hold hybrid securities — capital notes, perpetual notes, and Tier 1 and Tier 2 capital instruments issued by Australian banks and other financial institutions — these holdings have been a significant component of many retirement portfolios over the past 15 years. Hybrids combine features of debt and equity: they pay regular distributions (often franked), have very long or perpetual maturities with issuer call dates, and rank below senior debt but above ordinary equity in the capital structure. For retirees attracted by the yield (typically better than term deposits, often franked, with regular cash distributions), bank hybrids appeared to offer a sweet spot between fixed income and equity. But hybrids are more complex than they appear, and the tax treatment is more nuanced than ordinary shares or bonds. Distributions are typically franked dividends subject to the imputation system and the 45-day holding rule; conversion or redemption events trigger CGT consequences for the holder; loss-absorption clauses mean the principal can be written down in extreme scenarios; and the 2024 APRA reform ending Additional Tier 1 (AT1) hybrid issuance is reshaping the market and requiring retirees with substantial hybrid holdings to plan a managed exit.

The hybrid structure combines debt-like and equity-like features. Tier 1 hybrids — the most common form for retiree portfolios — have the most equity-like features: they are typically perpetual (no fixed maturity, but usually with issuer call dates after 5-7 years); distributions are technically discretionary in the sense that the issuer can choose not to pay (in practice the major banks have always paid); they include conversion or write-off triggers if the issuer's capital position deteriorates; and they rank below all other debt in default. Tier 2 hybrids are more debt-like: typically fixed terms (often 10 years), required distributions, still subordinated to senior debt but above Tier 1. Common Australian issuers include Commonwealth Bank (the CommBank PERLS series), Westpac (Westpac Capital Notes), ANZ, NAB, Macquarie Group, and others. Most major hybrids are listed on the ASX and trade like shares, with prices reflecting both the credit risk of the issuer and broader equity market conditions.

How are hybrid distributions taxed?

The tax treatment of distributions is generally favourable but specific. Most Tier 1 hybrid distributions are characterised as franked dividends for tax purposes — the distribution is grossed up by the franking credit, and the credit is available to offset tax or be refunded for nil-tax retirees (articles/2026-05-04-franking-credits-refundable-imputation-retirees). For a self-funded retiree on the franking credit refund, hybrid distributions deliver a similar after-tax yield to ordinary share dividends with franking — typically meaningfully above the gross yield of unfranked debt instruments. Some hybrid issuances have partially unfranked components, particularly where the issuer's franking account is constrained. Tier 2 instruments sometimes pay distributions treated as interest rather than dividends — taxed as ordinary income with no franking benefit, but also not subject to the 45-day rule. The distinction between franked dividend and interest treatment is specific to each hybrid's terms and should be confirmed from the issue documentation. For self-funded retirees with substantial hybrid holdings producing franking credits above the $5,000 small-shareholder threshold (or for any SMSF holding hybrids, where the exemption is not available at all), the 45-day holding period rule applies — short-term hybrid trading around ex-distribution dates risks losing the franking credit benefit (articles/2026-05-04-franking-credit-45-day-holding-period-rule-retirees).

What happens at a hybrid's conversion or call date?

The conversion events are where hybrid tax treatment becomes more complex. Many Tier 1 hybrids have specified conversion or call dates — typically 5-7 years from issuance. At the call date the issuer typically has the option to redeem the hybrid for cash (paying out the face value plus accrued distribution), convert the hybrid to ordinary shares of the issuer at a specified conversion ratio, or leave the hybrid outstanding (paying continuing distributions). For the holder, the consequences depend on which path the issuer chooses. Cash redemption is a CGT event — disposal of the hybrid at the redemption value, with the gain or loss calculated against the original cost base. For hybrids acquired at face value and redeemed at face value, the gain or loss is typically nominal; for hybrids acquired at a different ASX trading price, there is a real CGT consequence to consider. Conversion to ordinary shares is also typically a CGT event — disposal of the hybrid at its conversion value (number of shares received × the issuer's share price), with the cost base then carrying into the new ordinary shareholding. Some conversions may qualify for CGT rollover relief or specific cost-base rules under the issue's PDS terms; the documentation determines this case by case. Forced conversion at the issuer's option means the CGT consequences apply regardless of the holder's preference — the holder cannot avoid the event by holding through it.

What is the loss-absorption risk in a hybrid?

The loss-absorption mechanism is the most consequential feature retirees often overlook. Tier 1 hybrids include APRA-mandated provisions allowing the security to be written down or converted to ordinary equity if the issuer's capital ratios fall below specified regulatory thresholds, or if APRA exercises non-viability intervention powers. The mechanism is designed to ensure the hybrid genuinely absorbs losses in a crisis scenario, qualifying it as regulatory capital under APRA's prudential standards. In a write-off scenario the holder can lose all or part of their investment — the hybrid is written down to a fraction (or zero) of its face value, with no recovery available. The 2023 write-off of Credit Suisse AT1 hybrids was a global reminder that this loss-absorbing feature is real and can be triggered. Australian banks are well-capitalised and the trigger scenarios are extreme, but the risk is not theoretical, and it is one of the considerations that drove APRA's decision to phase the instrument out. For retiree investors, hybrids should be understood as carrying meaningful equity-like risk despite their bond-like distribution pattern — they are not substitutes for term deposits or government bonds in a defensive allocation.

Why is APRA phasing out bank hybrids?

The APRA AT1 phase-out is the central planning issue for retirees with hybrid exposure. APRA finalised its decision in 2024-25, with new prudential standards taking effect on 1 January 2027 and AT1 issued by banks expected to be fully phased out by 2032. The transition is designed to be orderly: AT1 issued before 1 January 2027 will be eligible to be counted as Tier 2 capital until the issuer's first call date for that instrument, after which it no longer counts toward regulatory capital. The reform reflects APRA's view, drawing on international experience and the Credit Suisse precedent, that AT1 has not always worked as intended in absorbing losses — being too complex, exposed to legal challenges, and capable of causing contagion when triggered. Simpler and more effective regulatory capital instruments are preferred. The practical consequences for retirees: new Tier 1 hybrid issuance from the major Australian banks will substantially decline from 2025-26 onwards; existing hybrids will mature, be called, or be converted over the phase-out period; and the secondary market for these instruments will shrink. For retirees holding bank hybrids as a long-term portfolio component, the reform requires planning for a managed exit — what replaces hybrid income when current holdings mature? Replacement options include listed corporate bonds (limited liquidity in the Australian market), term deposits (lower yield but more stable), increased equity allocation (more income but more volatility), and government bonds or fixed-income ETFs (defensive but lower yield). No single replacement is a perfect substitute for the hybrid yield-and-distribution profile; portfolio reconstruction will be needed for retirees with substantial hybrid weightings.

How concentrated is the risk across bank hybrid holdings?

The concentration risk is meaningful for many retiree portfolios. Australian retiree portfolios often have substantial hybrid exposure across multiple major bank issuers — CommBank, Westpac, ANZ, NAB. The intuition is that diversification across issuers reduces risk, but in practice the major Australian banks share substantial systemic correlation: they are all subject to the same APRA prudential framework, the same domestic economic conditions, the same residential mortgage exposure, the same banking sector dynamics. In a banking sector stress scenario, multiple bank hybrids would face write-off triggers simultaneously. The concentration is more concerning given the post-2024 APRA reform: the entire category is in a managed wind-down, with the banking sector as a whole exiting the AT1 market through 2032.

Worked planning examples

These two cases show how hybrid considerations apply in practice. Illustrative only — not personal advice — using FY25-26 figures.

Case 1 — Robert, 70, self-funded retiree. Holds $200,000 of bank hybrids across CommBank, Westpac and ANZ — purchased over the past 10 years for the yield. Annual distributions approximately $9,000 (mostly franked, with about $3,900 of attached franking credits — total Australian-share franking credits including some ordinary share dividends comfortably over the $5,000 individual threshold). On these facts, several considerations apply at once. The 45-day rule applies — Robert's total annual franking credits are above the individual small-shareholder threshold, so any short-term trading around ex-distribution dates would forfeit the franking credit. The APRA AT1 phase-out means his entire hybrid allocation is in a portfolio category that the major Australian banks are exiting between 2027 and 2032 — with hybrids issued before 1 January 2027 only counting toward Tier 2 until first call date, the banks have a strong commercial incentive to call rather than re-issue. The concentration risk is meaningful — all three holdings are in the major-bank sector with shared systemic exposure. On these facts the rational steps are to plan a managed exit over the APRA phase-out window: as each hybrid reaches its call date and is redeemed or converted, redeploy the proceeds into alternatives (listed corporate bonds for partial replacement of the yield, term deposits or fixed-income ETFs for safety, possibly an increased ASX 200 equity allocation), respect the 45-day rule on any remaining trades, and don't add to the position given the category is in wind-down. Held to maturity or call, the hybrids should generally produce the expected outcomes — the issue is replacing the income stream after the call, not panic-selling the existing positions.

Case 2 — Margaret, 75, self-funded retiree. Holds $120,000 in bank hybrids that have been performing as expected — quarterly franked distributions of approximately $1,800 per quarter ($7,200 a year). One of her hybrid holdings (e.g., CommBank PERLS XII) has a call date in 12 months. The current ASX trading price is approximately face value. On these facts the call date is the planning trigger. Likely scenarios are that the issuer calls the hybrid at face value — Margaret receives cash, with a CGT event calculated against her cost base (probably a small gain or loss if she paid close to face value) — or that the issuer converts to ordinary shares, in which case Margaret receives shares with a CGT event on the hybrid disposal and a new cost base in the resulting ordinary shareholding. Given the AT1 phase-out, the commercial incentive on the issuer side is generally to call rather than continue an instrument that no longer counts as Tier 1 capital. On these facts the rational steps are to confirm Margaret's cost base for this specific holding from her broker statement and the issue PDS, anticipate the call event in the cashflow plan, and pre-think the replacement of the income that the hybrid was providing (a $30,000-per-holding tranche typically produces $1,800-$2,000 a year of distribution — replacing it with a term deposit at current rates produces less, with a listed corporate bond produces broadly similar with credit risk, with ordinary bank shares produces similar after-franking yield with full equity risk). Brief Margaret on what to expect and the post-call deployment plan.

For self-funded retirees with hybrid securities in their portfolios, these holdings are a meaningful piece of the retirement-income picture — and one that is now in a managed transition under the APRA reform. The advice work is to inventory each client's hybrid holdings (issuer, type, call dates, current ASX price, cost base), confirm the tax treatment of distributions (franked dividend vs interest), apply the 45-day rule analysis for individuals above the small-shareholder threshold and for all SMSF clients, plan for upcoming call or conversion events with explicit CGT and replacement-income consideration, address the concentration risk in bank hybrid exposure, brief clients on the 2027-2032 APRA phase-out timeline and the need for a managed exit, and integrate the transition into broader retirement income planning. For too many retirees, hybrids are still treated as a permanent income allocation — but the post-2024 environment requires a deliberate transition out of these holdings over the coming six or seven years.
