Commonwealth Bank of Australia closed at A$175.64 on Friday, skimming the lower end of its intraday range—A$175.64 to A$179.56—but still hovering close to the upper reaches of its A$140.21-A$192.00 one-year band. For investors in the nation’s top lender, the dilemma persists: does the improving rate environment justify paying up at these levels?
Australia stood apart from other developed markets this week. The Reserve Bank of Australia raised its cash rate by 25 basis points to 4.1% in a tight 5-4 decision on March 17. Traders, according to Reuters, still fully priced in a jump to 4.35% by August, despite the close call.
It boils down to margin for the clean buy case. When rates move higher, banks typically manage to adjust loan pricing faster than deposit costs, pushing up net interest margin—the difference between earnings from loans and funding payouts. Belinda Allen, who heads Australian economics at CBA, pointed out the RBA’s discussion focused on when—not if—the next move comes. She’s sticking with her forecast for one more hike in May.
CBA’s got momentum working in its favor. Back in February, the bank posted a record first-half cash profit of A$5.45 billion and bumped its interim dividend up to A$2.35 a share. Home lending advanced 3.7%, business loans climbed 6%, and household deposits jumped 7.5%. Those numbers helped CBA steal business banking market share from National Australia Bank and ANZ. Michael Haynes at Atlas Funds Management pointed to business banking growth and what he called “operational excellence across mortgages” as key highlights. CEO Matt Comyn noted higher household spending, especially in discretionary areas. Reuters
Valuation is the main argument for selling here. According to MarketScreener, 14 analysts have an average target of A$127.44—well below the last close at A$177.36. That’s a steep 28% gap. Not much cushion if growth slows or pricing gets squeezed.
The trade isn’t set in stone. CBA confirmed it will push the March rate hike onto variable-rate mortgage holders from March 27. Retail banking exec Angus Sullivan acknowledged the move tightens household budgets, shifting how customers approach their money.
The RBA echoed the sentiment in its stability review, noting that while most households and businesses can handle bigger repayments, cash flow strains are likely to build over the coming year. There are already signs that riskier lending—mostly to investors and certain first-home buyers—has started to pick up.
The global picture is in play as well. In its review finalized March 18, the RBA flagged fast-moving developments in the Middle East, noting heightened volatility across energy and other markets. It warned this ups the odds of assets being repriced chaotically. For a bank still carrying a premium valuation, that’s no footnote.
CBA’s scale and deposit base still tick the right boxes for buyers, especially with the current rate environment giving earnings a nudge at the edges. But here’s the catch: those strengths can quickly flip to liabilities. If overdue repayments start piling up, loan growth slows, or the RBA holds steady, today’s sturdy-looking shares could start to look pricey fast.
