Shaping the Australian banking system for a changing economy
15.03.2026 - 01:53
Mandala’s latest research, prepared for the Commonwealth Bank of Australia, finds that Australian banking has been transformed beyond recognition by technology, globalisation, and regulatory change. However, policy has not kept pace. Major banks now face a shrinking revenue base while providing a growing suite of collective goods including regional branches, ATM networks, and payment infrastructure, that comparable financial institutions are not required to provide. The report finds that declining profitability and an uneven regulatory playing field amid rising geopolitical uncertainty place Australia's financial resilience at risk. It recommends three principles for policymakers to shape Australia’s banking system to best serve our national interest. First, consider system-wide impacts of policy settings. Second, apply the same obligations to firms conducting the same activities with the same risk. Third, assess how overseas firms operating in critical parts of the financial system would behave in a crisis.
Banking has radically changed. Significant technological and geostrategic developments have changed the structure of the world economy.
Banking is unrecognisable from what it was just 20 years ago. About 70% of transactions were made using cash in 2007. Today, that figure is around 13%. The value of mobile wallet transactions increased from $7 billion in 2018-19 to $160 billion in 2024-25. The value of buy-now-pay-later payments increased from $3 billion in 2017-18 to $19 billion in 2022-23. The percentage of mortgages that originated with a broker increased from 52% in 2014 to 75% in 2024.
While banking has changed, the narrative around banking remains decades out of date. It is unsurprising, given the above global forces, that economic metrics show banking in Australia is more competitive than ever. Competition has increased over time.
Regulatory decisions risk unintended consequences for the banking system. Regulatory interventions that increase banking costs or reduce revenue constrain major banks' organic capital generation. So too do arbitrage opportunities that allow fintechs and non-bank providers to operate outside the regulatory perimeter, while major banks continue to provide both digital-first offerings and legacy services.
Our current trajectory undermines the resilience of the Australian economy. This path puts Australia’s financial resilience at risk, too. Bank profits build shareholder capital, and shareholder capital is what allows lending to occur.
A banking system that best serves Australia’s national interest is one that is resilient, fair, and efficient. Three guiding principles can help policymakers develop a strong banking system that serves our national interest. First, consider system-wide impacts of policy settings. Second, apply the same obligations to firms conducting the same activities with the same risk. Third, assess how overseas firms operating in critical parts of the financial system would behave in a crisis.

Time to make a difference: Economic and fiscal benefits of Preventive Care+
Mandala's latest research, prepared for the Australian Self-Care Alliance, examines the economic and fiscal case for Preventive Care+, a proposed health assessment and coaching program for Australians aged 55 to 59. The research finds that early detection and self-care could deliver $233 million in combined health, income and fiscal benefits per cohort over ten years, including $26 million in net health system savings from delaying the progression of four common chronic conditions. Participants could also remain in the workforce for one to three additional years, generating $159 million in additional income, $19 million in additional superannuation contributions and $29 million in additional tax receipts per cohort over ten years. There are funded health checks for 45 to 49-year olds and 75 year-olds, but not for people in their late 50s, a period when chronic conditions frequently emerge and worsen. This report sets out the potential benefits of instituting a health assessment and a coaching program to intervene at a time that can yield meaningful outcomes.

Unlocking a Virtuous Cycle: Overcoming Barriers to AI in Australian Energy Systems
Mandala's latest research, developed in partnership with Microsoft, examines the barriers to transformative AI adoption in Australia's electricity system. The research finds that AI is one of the few tools able to unlock capacity and efficiency from the existing grid without waiting on new transmission and generation capacity, yet adoption today remains incremental. Three soft barriers, a lack of shared strategy, weak investment incentives and siloed data, are constraining Australia's ability to capture this potential. Overcoming them will require joint action from government, the technology industry and energy utilities to prove AI's value, align policy settings and fund pilots through to deployment.

Demonstrating the local benefits of AI infrastructure in Wisconsin
Mandala's latest research, prepared for Microsoft, examines the economic impact of hyperscale data center investment on Wisconsin's communities, businesses, and workforce. The research finds that committed data center projects will channel $16.5 billion to local suppliers, support more than 9,000 jobs during construction, and generate lasting economic activity across every county in the state, thereby extending Wisconsin's long tradition of industrial leadership into the AI era.

The essential infrastructure: How Australian banks power the economy
Mandala's latest research, prepared for the Australian Banking Association, examines the often-hidden role Australian banks play in supporting households, businesses and the broader economy. The research finds that banks are deeply embedded in the financial lives of Australians - as lenders, as community investors, through the jobs they generate and increasingly as assets owned by Australians themselves through shares and superannuation. From financing homes and small businesses to supporting regional communities through hardship and disaster, the report builds a picture of a sector whose success is broadly shared across the Australian population.
