SYDNEY, Jan 4, 2026, 16:16 ET — Market closed
- CBA last closed at A$161.12 on Friday, up 0.3% in the first session of 2026
- Traders are watching inflation data due Jan. 7 and Jan. 28 for the next shift in rate bets
- CBA’s half-year results and interim dividend are scheduled for Feb. 11
Commonwealth Bank of Australia shares (CBA.AX) ended Friday up 0.3% at A$161.12, their last close before markets shut for the weekend. The stock traded between A$160.49 and A$161.67 in the session. 1
The move left CBA near the top of the local market’s most closely watched names going into the first full trading week of 2026. Investors are returning from year-end with interest-rate expectations back in play, and Australia’s biggest lender tends to trade as a proxy for that debate.
That matters because bank earnings are tightly linked to net interest margin, the gap between what a lender earns on loans and pays on deposits and wholesale funding. Small changes in rate expectations can move bank valuations quickly, particularly for stocks like CBA that trade at a premium.
The broader market tone was steady. The S&P/ASX 200 closed Friday up 0.15% at 8,727.8, and all four major banks traded higher, an AAP market report carried by CBA’s newsroom said. Marketindex 2
CBA has built a short-term cushion on the chart. The stock has risen in six of the last 10 sessions and is up about 4% over the past two weeks, according to StockInvest. 3
Company-specific news has been quiet in the opening days of the year, leaving investors to lean on the last update from management and the macro calendar. In its September-quarter trading update in November, CBA reported cash profit of about A$2.6 billion and said headline net interest margin had eased as strong growth in lower-yielding liquid assets and institutional repos weighed on the mix. 4
The valuation question has not gone away. “The stock continues to be expensive on any metric,” Ord Minnett private wealth advisor John Milroy said after that update, as investors weighed competition in mortgages and deposits. 5
Rates are the next swing factor. The Reserve Bank of Australia left the cash rate unchanged at 3.60% at its December decision, and the central bank’s calendar shows its next monetary policy decision is due on Feb. 3. 6
Before that, traders get two key inflation checkpoints from the Australian Bureau of Statistics: the November CPI release scheduled for Jan. 7 and the December CPI release scheduled for Jan. 28. 7
The risk for CBA bulls is that inflation surprises on the upside and forces markets to price a more aggressive path for rates, pressuring funding costs and household credit demand at the margin. A separate downside is that competition in deposits and home loans continues to squeeze margins even if the policy rate stays still, a pressure the bank flagged in its last update.
The next hard catalyst for the stock is CBA’s half-year results and interim dividend announcement on Feb. 11, the bank’s financial calendar shows. 8
