Commonwealth Bank delivered a $10.98 billion cash profit for the 2026 financial year, but its valuation at 24 times forward earnings is raising concerns among analysts about downside risk.

Commonwealth Bank of Australia has reported a full-year cash profit of $10.98 billion for the 2026 financial year, up 7 percent from the previous year, but the result has done little to quell analyst concerns about the bank's stretched valuation. The stock is trading at 24.1 times forward earnings, a premium that reflects market confidence in CBA's dominant retail deposit franchise and its ability to expand margins in a higher interest rate environment. That confidence may be misplaced, according to analysts at UBS and Macquarie, who argue that the earnings growth is slowing and the valuation leaves little room for error if credit quality deteriorates or the Reserve Bank of Australia cuts interest rates sooner than expected.
The profit growth was driven primarily by business banking rather than the home loan book that has historically been CBA's earnings engine. Business lending volumes grew 9 percent year-on-year, and net interest margins in the business segment expanded as borrowers paid higher floating rates while deposit costs lagged. The shift is structurally positive for CBA's earnings stability, because business lending is less sensitive to housing market cycles than home loans, but it is also reducing the bank's sensitivity to the interest rate cycle that had supported margin expansion throughout 2025 and early 2026.
The net interest margin for CBA's retail banking business peaked at 2.15 percent in the June quarter of 2026 and has since edged down to 2.12 percent as competition for home loans intensified. The bank raised its standard variable home loan rate by 0.35 percentage points in May, following the RBA's cash rate increase, but it was unable to pass the full increase through to deposit rates because term deposit competition remains intense. The margin compression is expected to continue as the RBA holds the cash rate at 4.35 percent and the bank's fixed-rate loan book reprices to lower rates over the next 12 months.
CBA's total customer deposits grew 3.5 percent year-on-year to $720 billion, but the growth was concentrated in transaction accounts that pay minimal interest. The bank's reliance on cheap transaction deposits is a competitive advantage in a higher-rate environment, because it reduces the cost of funding relative to competitors that depend more heavily on wholesale funding and term deposits. The advantage is eroding, however, as customers shift savings into higher-yielding term deposits and mortgage offset accounts to reduce interest expenses on their home loans.
Credit quality remains stable, but the early signs of stress are appearing in the business lending book. CBA's impaired assets ratio rose to 0.82 percent in the June quarter, up from 0.71 percent a year earlier, driven primarily by commercial real estate exposures in the Sydney CBD office market and the retail sector. The bank increased its specific provision for credit losses to $1.2 billion for the full year, which is below the $1.5 billion provision taken in 2025 but above the $900 million provision taken in 2024.
The commercial real estate exposure is concentrated in office buildings with secondary-grade credentials that are struggling to attract tenants in a market where vacancy is at a 31-year high. CBA's exposure to commercial real estate is roughly $18 billion, of which roughly 40 percent is secured by office buildings in the Sydney CBD and metropolitan fringe. The bank has been reducing its exposure to secondary office stock since 2023, but the remaining portfolio is still vulnerable to further rental declines and value corrections.

The dividend of $5.05 per share, fully franked at 30 percent, represents a payout ratio of 73 percent of cash earnings, which is within CBA's target range of 70 to 80 percent. The dividend is sustainable provided that credit losses remain contained and the bank's capital ratio stays above its minimum requirement of 10.5 percent under the Basel III framework. CBA's common equity tier 1 ratio was 12.4 percent at the end of June, which provides a buffer of 190 basis points above the minimum and allows the bank to absorb roughly $12 billion in unexpected losses before breaching the requirement.
The buffer is comfortable by historical standards, but it is thinner than it appears when measured against the risk-weighted assets that are hidden in the bank's trading book and derivatives portfolio. CBA's total risk-weighted assets grew 6 percent year-on-year to $620 billion, driven by expansion in the business lending and institutional banking divisions. The growth is accretive to earnings, but it is also increasing the bank's systemic risk profile and drawing scrutiny from the Australian Prudential Regulation Authority, which has been warning banks against expanding risk-weighted assets too quickly in a low-growth environment.
Analysts at UBS, Macquarie, and Morgan Stanley have all issued price targets below the current market price, with the average target sitting at $108 per share compared with a market price near $120. The divergence reflects a debate about whether CBA's valuation is justified by its earnings quality or whether it is pricing in unrealistic margin expansion and credit stability. The bull case argues that CBA's deposit franchise is irreplaceable and that the bank will benefit from any future interest rate cuts because its deposit costs will fall faster than its asset yields. The bear case argues that the margin peak has already passed and that credit losses will rise as the property market corrects further.
CBA shares closed at $118.40 on the day of the full-year result announcement, down 1.2 percent from the previous close, reflecting a market that was satisfied with the profit but not with the outlook. The stock remains the largest component of the ASX 200, with a market capitalisation of roughly $380 billion, and its performance will continue to drive the index as long as the sector rotation favours banks over cyclicals.
