Sydney, Feb 2, 2026, 16:46 (AEDT) — The market has closed.
- Shares of Commonwealth Bank climbed 1.4%, even as the ASX 200 dropped by 1.0%.
- Markets are gearing up for the Reserve Bank of Australia’s Feb. 3 decision, with CBA set to report earnings on Feb. 11.
- Traders are weighing the impact of rising rates on bank margins and the risk of mortgage stress.
Commonwealth Bank shares closed Monday 1.4% higher at A$151.48, defying a 1.0% drop in Australia’s main index. The stock traded in a range from A$149.81 to A$152.89. ANZ Banking Group edged up 0.1%, while National Australia Bank slipped 1.0%. (Investing.com Australia)
The gain came just ahead of the RBA’s likely 25 basis point increase — a quarter-point bump — pushing the benchmark rate to 3.85% from 3.60%, per Investing.com data. Westpac’s chief economist Luci Ellis said the latest inflation figures “gets the casting vote.” Meanwhile, OCBC analysts warned of a possible “insurance” hike, which could leave future moves uncertain.

The RBA’s Monetary Policy Board will convene on Feb. 2–3, announcing its decision at 2:30 p.m. on the second day, followed by a media conference at 3:30 p.m., the central bank confirmed. Minutes are released two weeks after each meeting. (Reserve Bank of Australia)
CBA faces its next key event soon after. The bank will release half-year results for the period ending Dec. 31, 2025, on Feb. 11, per its investor site. (CommBank)
For bank investors, the direction of rates is crucial—it directly impacts the spread between earnings on loans and the costs of deposits and wholesale funding. This spread is typically measured by the net interest margin, which is interest income minus interest expenses, divided by interest-earning assets.
A higher cash rate may boost front-end margins, but it also pushes up funding costs and increases the risk of defaults among heavily indebted borrowers. Any sign the RBA plans more tightening would put that balance under pressure.
Monday’s action didn’t spell a broad risk-on mood. Heavy selling hit materials and gold-linked stocks, dragging the market down. Volatility in commodities spilled over into the index, forcing investors to be selective.
For Commonwealth Bank, the focus moves from “rates tomorrow” to “earnings next week.” Traders are keen to hear remarks on mortgage competition, credit quality, and costs, along with any hints about dividends.
There’s a clear risk on the downside. Should the RBA adopt a more hawkish stance than anticipated, or if its update reveals margin pressures or rising impairments, the recent rally in the stock could unravel fast.
The RBA decision drops Tuesday afternoon in Sydney, followed by Commonwealth Bank’s half-year results on Feb. 11. These two will drive the mood for Australian bank shares for the rest of the week.
