HIGHLIGHTS

  • CBA delivered unaudited cash NPAT of approximately $2.7 billion for Q3 FY26, down 1% on the first-half quarterly average but up 4% on the prior comparative quarter.
  • Both Macquarie Research and Jefferies have Underperform ratings on the stock, with price targets of A$114 and A$142.26 respectively — both significantly below the current trading price.
  • The stock has fallen approximately 14.77% over the past month, erasing gains built up earlier in the year, though it remains one of Australia's most widely held and closely watched stocks.

Commonwealth Bank of Australia (ASX:CBA) has been under sustained selling pressure over the past month, with the stock declining approximately 14.77% to A$156.42 as of 14 May 2026. This is a notable correction for a company that has long commanded a premium valuation relative to global banking peers, and it has reignited debate about whether the bank's structural Earnings advantages can continue to justify its elevated price-to-earnings multiple. On the day, the stock gained A$2.75 or 1.79%, offering a modest reprieve from the recent downward trend.

The context for this slide is multifaceted. CBA has consistently traded at a premium to its major Australian banking peers — Westpac, NAB, and ANZ — reflecting the market's view that its superior digital banking Franchise, retail deposit gathering capability, and technology-led efficiency improvements Warrant a Scarcity premium. However, with both Macquarie Research and Jefferies holding firm on Underperform ratings with price targets well below current levels, a growing segment of the institutional analyst community believes the Valuation Premium has become excessive.

Q3 FY2026 Trading Update: A Solid Result With Some Pressure Points

CBA's third-quarter trading update for the period ended 31 March 2026 showed an unaudited statutory net profit after tax of approximately $2.6 billion and cash NPAT of approximately $2.7 billion. Cash NPAT was down 1% on the first-half quarterly average — reflecting the impact of two fewer days in the March quarter — but up 4% on the prior comparative quarter. This underlying performance remains consistent with CBA's long-term track record of generating mid-single-digit earnings growth through a combination of Volume expansion and operational efficiency.

Operating Income was flat in the quarter. The bank noted that the benefit of lending and deposit volume growth largely offset the impact of two fewer calendar days in the period. Net interest income rose 1%, supported by deposit and lending volume growth, earnings on the replicating portfolio, and higher deposit margins. However, these tailwinds were partially countered by the impact of cash rate lag, a weaker New Zealand dollar, and competitive pressure in home and Business lending.

Operating expenses, excluding restructuring and notable items, increased 1% during the quarter, driven by higher Cloud Computing volumes, increased software licensing costs, and continued Investment in AI capabilities. These expense pressures were partially offset by the two fewer days in the period, a weaker NZD, timing benefits, and ongoing productivity initiatives. The bank's operating performance — a proprietary measure of operating income minus operating expenses — rose 1.7% on the first-half quarterly average and 5.6% on the prior comparative quarter.

Credit Quality: Cautious Signals Emerging

One area that drew analyst attention in the Q3 update was credit quality. CBA increased the forward-looking component of its collective provisions by $200 million during the quarter, or 8 basis points of gross loans and acceptances, citing heightened geopolitical and macroeconomic uncertainty. Loan Impairment expense for the quarter was $316 million, or 12 basis points of average gross loans and acceptances. Individual provisions remained flat at $0.8 billion, and actual credit losses remained low.

Consumer arrears showed modest increases driven by seasonal factors. Home loan arrears rose 6 basis points, credit card arrears increased 2 basis points, and personal loan arrears increased 30 basis points — the latter reflecting both seasonal factors and deliberate Portfolio Management decisions around credit settings, pricing, and Acquisition mix. Corporate Troublesome and Non-Performing Exposures (TNPE) increased to $6.5 billion, or 0.94% of Total Committed Exposure, reflecting movements in individual corporate names across a range of sectors. Management described the underlying portfolio credit quality as sound, but the increase in collective provision overlays suggests that the bank is preparing for the possibility of a more difficult economic environment ahead.

Volume Growth: Retail and Business Banking Both Performing

On a more constructive note, CBA continued to deliver disciplined volume growth across key product categories. Retail transaction accounts increased by more than 170,000 in the quarter, primarily driven by new-to-bank account openings — a metric that speaks to CBA's continued ability to attract new customers in a competitive banking market. Home loan new funding remained strong at $45 billion for the quarter, and for the twelve months to March 2026, home loan balances grew $41 billion at 1.0 times system growth, while household deposits grew $38 billion at 1.1 times system.

Business banking also showed encouraging momentum. Business transaction accounts grew 7% versus the prior comparative period to 1.4 million accounts, and business lending continued to grow above system pace with diversified growth across sectors. The bank maintained a disciplined approach to growth in what management described as a competitive market — language that acknowledges ongoing Margin pressure in the institutional and commercial lending space.

Broker View: Macquarie and Jefferies Remain Bearish

Despite the operational resilience evident in CBA's Q3 trading update, Macquarie Research has an Underperform rating with a price target of A$114, implying downside of approximately 27% from the current price of A$156.42. Jefferies similarly rates the stock Underperform with a target of A$142.26 — also implying meaningful downside of approximately 9%. Both Brokers are essentially making the same core argument: that CBA's fundamental earnings outlook, while solid, does not justify the valuation at which the stock currently trades.

Conclusion

Commonwealth Bank's Q3 FY26 trading update reinforces a familiar narrative: this is a very good bank, consistently delivering profits, growing volumes, managing credit quality carefully, and investing in the capabilities that will keep it competitive over the long term. The 14% share price decline over the past month is partly a valuation correction from what many in the institutional community viewed as an overly extended premium, and the Underperform ratings from Macquarie and Jefferies reflect a disciplined view that fundamental quality and appropriate pricing are two separate things. CBA remains one of Australia's most consequential and well-managed financial institutions, and the debate about its appropriate valuation is ultimately a question that each investor must resolve based on their own assessment of the bank's earnings trajectory, Dividend sustainability, and the price they are willing to pay for reliability.
