Australia’s major banks are adjusting their outlook for interest rates in 2026, and the message from economists is clear: rates could stay higher for longer before eventually falling.
Economists from Australia’s big four banks — Commonwealth Bank of Australia, Westpac, National Australia Bank, and ANZ — regularly publish forecasts on where the Reserve Bank of Australia (RBA) cash rate could head.
While predictions vary slightly, most agree on one key theme: interest rates are likely to remain elevated through 2026 before meaningful cuts begin later.
Here’s what the big banks are currently forecasting and what it could mean for borrowers.
Quick Answer: What Are the Big Four Banks Predicting for Interest Rates?
Most big four bank economists currently expect:
- The RBA cash rate could reach around 4.35%
- • Rates may remain elevated through most of 2026
- • Rate cuts may not begin until late 2026 or 2027
- • Inflation trends will determine the timing of future cuts
This outlook reflects ongoing inflation pressures and a strong labour market.
Why Interest Rates Are Still High in Australia
Interest rates rose rapidly between 2022 and 2024 as the RBA attempted to control inflation.
Although inflation has begun easing, several economic factors are keeping pressure on rates:
Key drivers influencing rate decisions
- Inflation still sitting above the RBA’s 2–3% target range
- Strong employment and a tight labour market
- Resilient consumer spending
- Global risks such as energy prices and geopolitical tensions
- Housing demand remaining strong in major cities
Because of these factors, the RBA has been cautious about cutting rates too early.
Big Four Bank Cash Rate Forecasts for 2026
While exact predictions differ, most big bank economists believe the cash rate could peak around 4.35% before eventually falling.
Commonwealth Bank Forecast
Economists at Commonwealth Bank of Australia have suggested interest rates could remain elevated for much of 2026 before gradual easing begins if inflation continues to fall.
Key expectations
- Possible short-term rate increases or pauses early in 2026
- Gradual cuts once inflation sustainably returns to target
- Housing demand likely to remain strong
CBA economists believe the timing of cuts will depend heavily on inflation data.
Westpac Forecast
Economists at Westpac have warned the RBA may need to keep policy tight for longer.
Their outlook suggests:
- Potential back-to-back rate hikes if inflation surprises higher
- The cash rate possibly peaking around 4.35%
- Rate cuts pushed further into late 2026 or beyond
Westpac has emphasised that the RBA will prioritise inflation control over short-term growth concerns.
NAB Forecast
According to economists at National Australia Bank, the central bank may adopt what they describe as a “policy of least regret” approach — acting earlier rather than waiting for inflation to re-accelerate.
NAB’s outlook includes:
- Additional tightening if inflation remains persistent
- Interest rates staying high throughout most of 2026
- Cuts potentially beginning later than markets initially expected
ANZ Forecast
ANZ economists generally align with the broader consensus that the RBA will remain cautious.
Their expectations include:
- Rates staying around current levels for much of 2026
- Gradual easing only once inflation stabilises
- Continued resilience in employment and economic growth
