Reimagining banking operating models in Australia for 2026 and beyond

Australian banks are intensifying their focus on operational efficiency to navigate a competitive and evolving financial landscape. Despite substantial investments in technology and process enhancements, the average cost-to-income ratio among Australia's major banks reached 49.2% in the first half of 2025, up by 89 basis points from 1H 2024, highlighting the need for more transformative strategies to achieve significant productivity gains. 

As advanced technologies such as artificial intelligence (AI), automation, and predictive analytics mature, Australian banks are increasingly leveraging these tools to optimise operations, enhance customer experiences, and strengthen risk management frameworks. However, the journey toward operational excellence requires more than just technological upgrades; it necessitates a comprehensive reimagining of operating models that prioritise scalability, flexibility, and integration across systems and processes.

So, what key imperatives should Australian banks focus on to enhance operational efficiency? How can they strike the right balance between innovation, cost optimisation, and resilience? Let's explore these critical themes in this article.

Resilience: The Cornerstone of Banking

Operational resilience has become a central focus for Australian banks, driven by rising regulatory pressures and evolving risks. To strengthen the financial sector's ability to withstand disruptions, the Australian Prudential Regulation Authority (APRA) implemented CPS 230 – Operational Risk Management in July 2025. CPS 230 emphasises proactive risk management, ensuring banks can maintain critical operations during disruptions and effectively oversee third-party risks. With the standard now in force, banks must reassess resilience strategies, strengthen oversight frameworks, and embed practical mechanisms to handle future shocks.

The need to modernise IT infrastructure, manage third-party risks, and ensure cybersecurity resilience is more pressing than ever. Banks have made considerable investments in these areas, establishing foundational resilience measures such as periodic stress tests, disaster recovery plans, and cybersecurity frameworks. However, to truly thrive in this increasingly complex environment, banks must adopt proactive, agile, and innovative strategies that go beyond compliance-driven approaches.

Looking ahead, banks must integrate cutting-edge technologies, including AI-powered cybersecurity tools, digital twins, and decentralised IT architectures, to foster resilience. By using predictive threat intelligence and anomaly detection powered by AI, banks can move from reactive to proactive security measures, identifying vulnerabilities before they become threats. 

Additionally, banks need to modernise their core systems with cloud-native platforms and adopting multi-cloud strategies to reduce reliance on any single provider. The importance of third-party risk management cannot be overstated, and banks must collaborate with ecosystem partners, fintechs, and regulators to create a cohesive, collective resilience framework. More than just compliance, this strategic approach will enable banks to safeguard their operations, protect customer trust, and capitalise on opportunities in the evolving digital era.

Strategic Imperatives for Cost Reduction

The pursuit of cost-to-income ratios below 40% has become a defining metric for operational excellence in banking. This goal reflects the industry's response to digital transformation, heightened shareholder expectations, and mounting competition from fintechs and neobanks, all of which demand leaner, more efficient operations. Despite substantial investments - banks globally allocate approximately $600 billion annually to technology - the anticipated productivity gains, particularly in developed markets like Australia, remain elusive.

To overcome these challenges, banks must focus on strategic imperatives: modernising technology, streamlining operations, and investing in targeted innovations. Accelerating the shift to cloud-native platforms and hybrid cloud solutions will be pivotal, enabling scalability and cost optimisation while enhancing operational flexibility. Automation, powered by robotic process automation (RPA) and AI, can drive efficiencies by eliminating repetitive tasks, enhancing fraud detection, and optimising risk assessments. Centralised data platforms must replace fragmented systems, fostering real-time analytics and ensuring better data governance for compliance and resource optimisation.

Enhancing Organisational Agility

Operational efficiency in banking is defined by the need for agility, particularly in processes supporting ecosystem collaboration. With partnerships among fintechs, big techs, and third-party providers becoming integral to delivering innovative, value-added services, banks must evolve rapidly.

Legacy IT systems, organisational silos, and regulatory frameworks pose significant challenges, necessitating a shift toward modular architectures and API-first approaches that enable seamless data exchange and system interoperability. This shift not only facilitates faster rollouts of new offerings but also ensures compliance in a rapidly changing regulatory landscape.

Cultural transformation also plays a crucial role. Banks must embed a mindset of experimentation and collaboration, with leaders modelling openness to change. Training programs can prepare employees to navigate external partnerships, while advanced data tools can enable real-time decision-making and hyper-personalised customer experiences. By fostering a resilience-first, agile culture, banks will unlock the potential of ecosystem partnerships to deliver long-term value.

Conclusion

In 2026 and beyond, operational efficiency through agility and resilience is not optional, it is a strategic imperative. Australian banks that proactively embrace advanced technologies, foster collaborative ecosystems, and prioritise a resilience-first culture will not only navigate disruptions with confidence but also position themselves as leaders in the industry. By continuously evolving their strategies and investing in innovative solutions, they can turn operational efficiency into a sustainable competitive advantage, ensuring sustained trust, stability, and growth in an increasingly complex financial landscape.
