Why consolidation of mutual banks is the name of the game
As Australia’s banking sector evolves amidst fierce competition, stringent regulations, and the need for (and high costs of) technological investment, a wave of consolidation is sweeping through the sector - and it shows no signs of slowing down. Recent high-profile mergers and acquisitions, such as Qudos Bank teaming up with Bank Australia, Australian Settlements Limited's sale to Banking Circle S.A., and the Auswide Bank-MyState Limited merger, are just the tip of the iceberg. The landscape has been further transformed by significant transactions like Suncorp Bank’s acquisition by ANZ and a flurry of previous mergers among mutual banks, including Heritage Bank and People’s Choice, as well as Greater Bank and Newcastle Permanent Building Society.
“Australia’s 131 banks differ in size by several orders of magnitude. … The 74 smallest banks make up 6% of the banking system and are mostly mutual institutions; the number of mutual institutions has fallen from over 200 in the year 2000 as credit unions and building societies (CUBS) have consolidated.”

In a sector already known for its regulatory complexities, navigating these deals is no small feat. Yet, the mutual banking sector is particularly intriguing, as many discussions around potential mergers often fizzle out, stuck in the limbo in the non-binding ‘MoU’ stage. In part, this is driven by the fact that, by and large, mutuals live and breathe in a unique organisational culture which is acutely member-centric and steeped in localised history. In a dealmaking context, there is invariably a range of philosophical views around the boardroom table, generally more emotion in the negotiation, and often a reluctance (from the ‘smaller’ player) to be perceived as being ‘taken over’.
In this article, we delve into the compelling dynamics of mutual bank mergers, exploring the threshold considerations that make dealmaking in this sector not just challenging, but utterly fascinating. Buckle up as we navigate the complexities of Australia’s banking consolidation journey!
Drivers of consolidation
So, what’s fuelling this trend? A mix of factors is driving mutual banks to merge, reshape, and redefine their futures:
- Scale matters: The need to achieve scale through a larger loan and deposit books and a broader capital base to maintain liquidity, fund growth and remain competitive.
- Diversification is key: Banks are on the hunt for greater customer and product diversification. By broadening their offerings, they aim to unlock new growth opportunities, mitigate risks, and enhance customer satisfaction.
- Digital transformation imperative: The imperative to significantly invest in digital infrastructure and technology to deliver modern banking services.
- Competing with giants: The ongoing challenge of competing with larger commercial banks in the context of Australia’s prudential framework and more limited capital options (the hope of mutual capital instruments (MCIs) as an accessible form of Common Equity Tier 1 capital for mutuals following the Hammond Report has, unfortunately, not yet been realised).
- Robust risk management: As threats like fraud and cybercrime become increasingly sophisticated, banks must elevate their risk management practices. Protecting members and institutions from emerging risks is paramount.
- APRA’s regulatory influence: APRA’s focus on recovery and exit and resolution planning – which has forced a number of organisations to be ‘merger-ready’.
Each deal is different, and so the relevant drivers ultimately dictate the universe of potential merger parties.
Threshold considerations in contemplating a merger
Mutual mergers can be structured in a number of ways, having regard to:
- The relative size of each entity and its assets and liabilities.
- Company type, capital structure and historical constitutional idiosyncrasies.
- Integration considerations (principally the relative maturity of technology infrastructure and banking platforms).
- Size and geographical spread of asset portfolio and members.
- Other legal, tax and accounting considerations.
In thinking about any merger, some of the key threshold considerations are as follows:

An early focus on these key areas goes a long way to surfacing threshold key issues at the outset of any merger discussion. Given the drivers of consolidation are only amplifying, we expect the number of those discussions will only increase throughout 2025.
