Non-Interest Income in Australia: How Banks Are Diversifying in 2025

Australian banking has traditionally relied on the margin between what banks pay depositors and what they charge borrowers. But 2025 marks a clear pivot: non-interest income is now central to bank strategy, resilience, and consumer experience. As interest rates remain volatile and regulatory changes bite, understanding non-interest income is crucial for anyone watching Australia’s financial sector.

What Is Non-Interest Income – and Why Does It Matter?

Non-interest income refers to all bank earnings that don’t come from charging interest on loans. Instead, this revenue comes from activities such as fees, commissions, trading, and advisory services. In the current climate, non-interest income has become vital for banks facing compressed net interest margins and increased competition from digital disruptors.

• Examples: Account maintenance fees, credit card fees, wealth management commissions, insurance premiums, and trading income.
• Why it matters: It offers banks revenue diversification, lowers reliance on lending cycles, and provides a financial buffer during periods of weak loan growth.

For consumers, these income streams often mean more service options—but also potentially higher or more complex fees.

2025 Trends: How Non-Interest Income Is Shaping Aussie Banking

Several key trends are driving the rise and transformation of non-interest income across Australian banks this year:

• Fee Restructuring: Major banks like CBA and NAB have reviewed their fee structures in response to ASIC’s 2024/25 consumer fee transparency guidelines. Expect more transparent, tiered, or bundled fee offers.
• Growth in Wealth & Insurance: After years of divestment, banks are tentatively returning to wealth management and insurance—often via digital platforms and partnerships—chasing new advisory and commission income.
• Payments & Tech: As open banking and real-time payments expand, banks are launching new payment services for both retail and business customers, generating transaction fees and value-added service charges.
• Corporate Services: Trade finance, FX, and business advisory services are in demand from SMEs adapting to global supply chain pressures and a weaker AUD in early 2025.

Real-world example: In Q1 2025, Westpac reported a 9% year-on-year increase in non-interest income, with digital payment solutions and SME advisory services leading the growth.

Risks, Criticism, and the Road Ahead

While non-interest income is crucial, it’s not without controversy or risk. Some of the main issues include:

• Fee Creep: Regulators and consumer advocates warn against excessive or ‘junk’ fees. The Australian Competition and Consumer Commission (ACCC) is closely monitoring fee disclosures and their justifications in 2025.
• Volatility: Trading and investment income can be unpredictable, especially during global market shocks or geopolitical events.
• Reputational Risk: Aggressive cross-selling or hidden fee practices can damage trust, as seen in the aftermath of the Banking Royal Commission.

For banks, the challenge is to balance the search for revenue with transparency and customer value. For consumers, it’s essential to scrutinise account statements and be aware of the ‘real’ cost of banking services beyond just loan rates.

What’s Next for Non-Interest Income in Australia?

Looking ahead, non-interest income is likely to become even more important as digital services expand and traditional lending faces tighter margins. Expect further innovation in payments, digital advice, and bundled service offerings. At the same time, regulatory scrutiny will ensure that fee structures remain fair and transparent.

For Australians, staying informed about how banks make their money—and how it impacts your wallet—will be key in 2025 and beyond.
