Commonwealth Bank of Australia finished Friday at A$175.64 after trading between A$175.64 and A$179.56, leaving the stock near the top of its A$140.21-A$192.00 one-year range. That keeps a hard question alive for investors in Australia’s biggest lender: whether a better rate backdrop still outweighs an already rich price. 1
Why it matters now is that Australia was the outlier among major developed markets this week. The Reserve Bank of Australia lifted the cash rate by 25 basis points, or a quarter of a percentage point, to 4.1% in a 5-4 split on March 17, and Reuters reported traders fully priced a move to 4.35% by August even after the close vote. 2
The clean buy case is margin. When rates rise, banks can often reprice loans faster than deposits, lifting net interest margin — the gap between what they earn on loans and pay on funding. Belinda Allen, CBA’s head of Australian economics, said the debate at the RBA was about timing, not direction, and kept her call for another May hike. 3
CBA has operating momentum behind that view. In February it reported record first-half cash profit of A$5.45 billion, lifted its interim dividend to A$2.35 a share and said home lending rose 3.7%, business lending 6% and household deposits 7.5%. Those gains helped it take business banking share from National Australia Bank and ANZ, and Michael Haynes of Atlas Funds Management said the standout was growth in business banking and “operational excellence across mortgages”; CEO Matt Comyn, for his part, said household consumption had risen across discretionary categories. 4
The sell case starts with valuation. MarketScreener data show the average target from 14 analysts at A$127.44 against a last close of A$177.36, a gap of about 28%, which leaves little room if earnings growth cools or pricing pressure returns. 5
But the trade can still turn. CBA said it will pass the March rate increase through to variable-rate home loans from March 27, and retail banking executive Angus Sullivan said rate changes add pressure to household budgets and alter how customers plan their finances. 6
The RBA’s own stability review struck a similar note. It said most households and businesses are well placed to absorb higher payments, but cash flow pressure is expected to rise over the next year and there is early evidence that some riskier lending — especially to investors and some first-home buyers — has ticked higher. 7
There is the global backdrop too. The RBA said in that review, finalised on March 18, that the Middle East conflict was evolving rapidly and had already lifted volatility in energy and other markets, increasing the risk of a disorderly repricing of assets. For a bank still trading on a premium valuation, that is not a side issue. 8
For now, CBA still has what buyers want: scale, deposits and a rate backdrop that can help earnings at the margin. The snag is that the same forces making the shares look sturdy today could make them look expensive in a hurry if overdue repayments rise, loan growth cools or the next RBA move never comes.
