- CBA ended Friday at A$175.64, down 0.97%; National Australia Bank fell 2.25%, Westpac 1.05% and ANZ 1.13%. 1
- Weekend oil tensions added a fresh risk before the ASX reopen; Reuters said Brent settled Friday at $112.19 a barrel and could rise further on Monday. 2
- The Reserve Bank of Australia lifted its cash rate, or benchmark policy rate, to 4.10% last week, and CBA said it will pass through the move on home loans and eligible variable-rate business loans from March 27. 3
Commonwealth Bank of Australia heads into Monday’s trade on the back foot. Its shares finished Friday at A$175.64, down 0.97%, as investors braced for another week of rate and inflation shocks; CBA still fell less than NAB, Westpac and ANZ. 1
The move matters because CBA is Australia’s largest lender, and Friday’s A$943.4 million in traded value showed how tightly the market still tracks it. With the Reserve Bank having just raised rates and oil risks flaring again over the weekend, investors are back weighing whether higher borrowing costs will help bank income more than they hit loan demand and household finances. 4
The RBA last week raised the cash rate by 25 basis points, or a quarter percentage point, to 4.10% in a 5-4 vote, its closest since it began publishing tallies. CBA said its home-loan variable rates and eligible variable-rate business lending would also rise by 25 basis points from March 27. 3
Angus Sullivan, CBA’s retail banking chief, said the bank recognised rate changes can put “additional pressure on household budgets”. That lands harder now because Reuters reported oil was poised to push higher again on Monday after weekend threats around the Strait of Hormuz. 5
Even so, CBA comes into the week with solid recent operating momentum. The bank reported record first-half cash earnings — its preferred measure of underlying profit — of A$5.45 billion in February, driven by gains in home loans, business loans and deposits, and the stock jumped as much as 8.4% on the day. 4
Friday’s tape underlined how much attention the name still pulls: CBA was the ASX’s second-most traded stock by value, behind only BHP. 1
Belinda Allen, CBA’s head of Australian economics, said earlier this month that “the balance of probabilities has shifted” toward more tightening after fresh RBA signals. She said again on March 19 that Australia’s February CPI, due on March 25, “will be critical for the outlook.” 6
Still, the trade is not simple. Higher rates can lift what banks charge on loans, but they can also slow credit growth and test borrowers if mortgages, petrol and daily costs all rise together; Reuters data show CBA still carries an Underperform consensus from 14 analysts. 2
Reuters reported on Sunday that Brent closed Friday up 8.8% for the week and was expected to rise further on Monday, a reminder that bank investors are staring at a macro problem, not just a banking one. 2
For now, Wednesday’s inflation reading is the next hard marker for CBA shares. A firm print would likely keep rate fears alive — an inference supported by Allen’s warning that CPI will be critical — just as CBA’s own higher loan rates take effect later this week. 7
