SYDNEY, March 17, 2026, 09:16 (AEDT)
Commonwealth Bank of Australia (CBA.AX) shares picked up 1.02% to finish at A$175.53 on Monday, March 16, marking their strongest close in over two weeks. Investors gravitated toward rate-sensitive banks despite the broader market weakness, with the S&P/ASX 200 slipping 0.4% as traders braced for the Reserve Bank of Australia’s policy decision.
CBA’s strength stood out, propping up some of the slack as miners dragged the Australian market down on softer commodity prices. The Australian bank giant’s move carries weight—not least because traders are watching the country this week, which looks set to diverge from global peers as central banks meet. According to Reuters, 23 out of 30 economists anticipate the RBA will hike rates on Tuesday.
Financials picked up 0.4% Monday, led by CBA at the front of the pack. Energy names advanced as well, but miners lagged: Rio Tinto gave up 2%, Fortescue was off 3.9%, and BHP slipped 1.2%. That left CBA’s outperformance more striking than the index headline implied.
“Geopolitical risk premium could persist,” said Cliff Man, chief executive at ETF Shares, in comments to Reuters, even if oil prices retreat after the conflict. That’s relevant for Australian banks—the oil shock has reignited inflation jitters and firmed up expectations for another RBA hike. The Economic Times
Just a few days back, Commonwealth Bank lined up with Westpac and National Australia Bank, pushing for another rate rise. “The balance of probabilities has shifted,” said Belinda Allen, who heads up Australian economics at CBA. Deutsche Bank’s Phil O’Donaghoe admitted his team had misjudged March risk—now, unless the Middle East conflict takes a turn for the worse, a hike is their expected outcome. Reuters
Governor Michele Bullock hasn’t ruled it out. Earlier this month, she described every meeting as “live” and cautioned that if energy prices stay elevated for longer, demand and growth could take a hit, but inflation might keep rising. A 25-basis-point increase—just to recap, that’s a quarter of a percentage point—would push the cash rate up to 4.1% from 3.85%. Reuters
CBA’s rally picked up speed following last month’s results. The bank delivered a record A$5.45 billion first-half cash profit, and the stock surged as much as 8.4% that day. Growth in home loans, business lending and deposits outpaced a modest tightening in net interest margin—a closely watched gauge of the spread between lending and deposit rates.
Michael Haynes at Atlas Funds Management pointed to business-bank gains and what he called “operational excellence” in mortgages as the highlights of the result. CBA reported holding its 25.4% slice of the home-loan market, underscoring the scale that’s kept it ahead of the pack. Reuters
The major banks remain on solid ground. February trading updates pushed Westpac and ANZ to all-time highs, and NAB followed suit after posting a 16% jump in first-quarter cash earnings. In short, investors are sticking with the lenders even as rate signals turn less clear, rather than shifting to more cyclical picks.
The trade’s anything but straightforward. Elevated rates chill lending and put pressure on consumers; Bullock has cautioned that a prolonged energy shock threatens to drag on demand while simultaneously stoking inflation. CBA, according to Reuters stock data, still sits with an Underperform consensus from 14 analysts as of March 5—valuation concerns are sticking around.
The RBA’s decision on Tuesday comes up next. CBA’s interim dividend lands March 30. Should rates go higher, traders will scan for signs May is also in play; a pause, and the rate-fueled rally that carried CBA to A$175.53 may lose steam fast.
