Commonwealth Bank of Australia (ASX: CBA) has forecast that the Reserve Bank of Australia will raise the official cash rate at both its March and May 2026 policy meetings. The RBA interest rate predictions from CBA point to two consecutive 0.25% increases, which would take the cash rate back to 4.35%, a level not seen since late 2023. The forecast marks a sharp shift from the rate-cut expectations that dominated much of 2025.

The change in the Australian economy 2026 outlook has been driven by a combination of persistent domestic inflation, a tight labour market, and rising global energy prices linked to the Middle East conflict. CBA now believes the balance of risks clearly favours further tightening, placing it alongside ANZ and Westpac in expecting the RBA to act at its next meeting.
Why CBA Has Revised Its RBA Interest Rate Predictions?
CBA’s revised RBA interest rate predictions stem from a domestic economy that continues to operate above its sustainable capacity. Annual GDP growth of 2.6% exceeds the RBA’s estimated long-term speed limit of approximately 2.1%, indicating that demand is still running ahead of the economy’s productive capacity.

The unemployment rate has held at 4.1% for two consecutive months, remaining below estimates of the non-accelerating inflation rate of unemployment. CBA notes that inflation remains above the RBA’s target band, with trimmed-mean inflation expected to reach around 0.9% in the first quarter of 2026 and 0.8% in the second quarter.
The Middle East Conflict and Its Impact on the Australian Economy 2026 Outlook
The Australian economy 2026 outlook has been complicated by the escalating Middle East conflict, which has sent global oil prices surging above US$100 per barrel. CBA has identified this development as a significant new source of upward pressure on domestic inflation, particularly through energy costs.
CBA head of Australian economics Belinda Allen noted that while global uncertainty has increased, the domestic economy is still proving resilient. She added that inflation remains too high and the labour market is tight, which keeps pressure on the Reserve Bank to act.
Two Back-to-Back Rate Hikes Would Return the Cash Rate to 4.35%
CBA expects the RBA to lift the cash rate by 0.25% at its March meeting and follow up with another 0.25% increase at the May meeting. This would return the official cash rate to 4.35%, a level last reached in November 2023 and one that has not been exceeded since November 2011.
The March meeting marks a significant turning point for RBA interest rate predictions across the market. ANZ and Westpac have both aligned with CBA’s view, reflecting a growing consensus among Australia’s major banks that the RBA will tighten policy in the near term.
RBA’s Own Stance and Recent Commentary
The RBA’s own communications have supported CBA’s revised RBA interest rate predictions. Both Governor Michele Bullock and Deputy Governor Andrew Hauser have emphasised the importance of preventing inflation expectations from becoming entrenched following the sharp rise in prices in recent years.
In its February decision statement, the RBA noted that some of the increase in inflation reflects greater capacity pressures and that inflation is likely to remain above target for some time. The board judged it appropriate to increase the cash rate target at that meeting, and CBA believes the March meeting will produce the same outcome.
Signals That Could Complicate the Banking Sector Opportunities Picture
Not all indicators point in the same direction. CBA acknowledges that household spending was weaker than expected in late 2025, and the bank’s own card spending data showed a pullback in February before a modest recovery in March. Unit labour costs have also moderated, and wage growth has not shown signs of reaccelerating.

These crosscurrents present a finely balanced decision for the RBA, and they also introduce some caution into the banking sector opportunities outlook. Higher rates generally support net interest margins for lenders, but sustained pressure on household spending could weigh on credit demand and asset quality over time.
Industry Outlook
Rising interest rates are a double-edged development for the Australian banking sector. On one hand, higher cash rates support net interest margins and create near-term banking sector opportunities for lenders with variable-rate mortgage books. On the other hand, sustained rate increases can compress household budgets and slow credit growth, introducing longer-term risks.
The Australian economy 2026 outlook will be shaped significantly by how quickly inflation responds to tighter monetary policy. If the RBA’s March and May moves achieve their intended effect, the case for further hikes beyond 4.35% weakens. If inflation proves stickier than forecast, the rate cycle could extend further than current RBA interest rate predictions suggest.
Future Direction and Impact on the Australian Economy 2026 Outlook
The RBA’s March 2026 decision, due on 17 Mar 2026, will be the first test of CBA’s updated forecast. If the RBA delivers the expected 0.25% hike, attention will immediately shift to the May meeting and whether the second move follows as anticipated.
For those tracking banking sector opportunities and the broader Australian economy 2026 outlook, the trajectory of global energy prices and domestic inflation data will be the key variables to watch. CBA’s RBA interest rate predictions place the peak cash rate at 4.35%, but the bank has acknowledged that the rapidly evolving global picture could shift that view further.
