Australia's September 2026 CPI Hits 4.3% — All Four Major Banks Now Tip a November Rate Hike

Key takeaway: Australia's September quarter CPI came in at 4.3% annual growth — well above the RBA's 2–3% target band. Within hours of the release, all four major Australian banks updated their forecasts to include a November 3 rate hike, which could push the cash rate to an 18-year high.

What Today's CPI Print Signals

Australia's inflation remains stubbornly above the Reserve Bank of Australia's 2–3% target band. The Australian Bureau of Statistics (ABS) confirmed today that the September 2026 Consumer Price Index recorded 4.3% annual growth — a reading industry analysts describe as "still too hot to handle" that directly strengthens the case for further monetary policy tightening.

The result lands on the same day that RBA Governor Michele Bullock delivered an Opening Statement to the Senate Economics Legislation Committee, where she faced questions about the Bank's inflation-fighting strategy. With CPI at 4.3%, the Governor's task of defending a hold at 4.60% has become significantly harder.

The RBA has kept the cash rate unchanged at 4.60% since 30 September 2026. Markets and the major banks now overwhelmingly expect that hold to end at the 3 November board meeting.

Why All Four Major Banks Have Shifted to a November Hike

The shift in bank forecasts is striking in its unanimity. As of 28 October 2026, all four major Australian banks have revised their outlooks to include a rate rise at the November meeting — a consensus position that did not exist earlier this month.

The trigger is a CPI print that materially exceeded the RBA's tolerance. With the cash rate already at 4.60% and annual inflation still running at 4.3%, the Board faces direct pressure to act. Should a hike proceed, Australia's official cash rate would reach levels not seen in approximately 18 years.

"All four major banks now expect a November rate rise, putting an eighteen-year high official cash rate within reach." — The Adviser, 28 October 2026

The broader economic backdrop complicates the picture: GDP grew just 0.4% in the June quarter (ABS), and the unemployment rate has risen to 4.7% in September. Yet the RBA has consistently signalled that returning inflation to the 2–3% band remains its primary mandate, even at some cost to near-term growth.

How a Rate Rise Affects Mortgage Holders

Each 0.25% increase in the cash rate typically adds approximately $65–$80 per month to a $500,000 variable rate mortgage, depending on the loan structure and lender. For borrowers on a standard variable rate directly linked to the cash rate, the impact lands within weeks of any decision.

The groups with the highest immediate exposure include:

• Property investors with multiple variable-rate loans
• Self-employed borrowers on variable rate products who may not have planned for another increase
• Commercial property owners whose loan covenants are sensitive to rate movements
• First-home buyers who stretched to buy at current values and rates

The key question for many is whether to lock in a fixed rate now — before the November increase takes effect — or to hold and absorb the risk.

What This Means for MPFG Borrowers

For self-employed borrowers and those using alternative documentation, the November rate outlook reinforces the value of acting before, not after, a rate decision. MPFG Capital's Easy Refinance product is designed for borrowers looking to escape high bank standard variable rates — with loan amounts up to $7.5M and flexible income verification available for Alt Doc applicants who cannot provide standard payslips.

Whether you hold a residential investment loan, a commercial property facility, or a bridging arrangement, an independent assessment from a non-bank lender before 3 November can clarify your options at current rates. Our Camberwell (Melbourne) and Pymble (Sydney) offices are available ahead of the decision.

FAQ

If the RBA raises rates in November, how much will my repayments increase?

Each 0.25% cash rate increase typically adds around $65–$80 per month to a $500,000 variable rate mortgage, depending on your lender, loan term, and whether you are on a principal-and-interest or interest-only structure. The impact on larger balances — common for commercial and investment loans — is proportionally higher.

Can self-employed borrowers still refinance before the November RBA decision?

Yes. MPFG Capital's Alt Doc and Easy Refinance products do not require standard payslips. Borrowers who can provide BAS statements, an accountant's letter, or 6–12 months of business bank statements may qualify for a structured refinance even if they have been declined by the major banks. Applications submitted before the November board meeting can be assessed under current rate conditions.

Should I wait for the 3 November decision before refinancing?

Waiting carries a risk: lenders typically adjust their pricing within days of an RBA announcement. If your current variable rate is already above 6%, the potential saving from refinancing now — rather than after a further increase — may be material. An independent assessment costs nothing and takes the guesswork out of timing.
