The Reserve Bank of Australia has delivered its third cash rate increase of 2026, lifting the official rate to 4.35% and sending shockwaves through the mortgage market. For borrowers already stretched by cost-of-living pressures, the cumulative impact of this year's hikes is now becoming painfully clear.
Three Hikes, One Big Bill
The RBA's tightening cycle began earlier this year as inflation proved stickier than forecasters had hoped. Each 0.25% increase adds roughly $90 per month to repayments on a $600,000 mortgage — and with three hikes now in the rear-view mirror, that's an extra $272 a month compared to the start of the year.
For the average Australian household with a mortgage, that's money directly out of the weekly budget. And it's not just new borrowers feeling the squeeze: existing customers on variable rates are seeing their repayments climb automatically as lenders pass on the increases.
The Big Four Respond
Within days of the October RBA decision, all four major banks announced they would pass on the full 0.25% increase to variable rate customers, effective from 9 October 2026. Commonwealth Bank, ANZ, Westpac and NAB all confirmed the move, bringing their lowest variable rates to around 6.09%–6.25% for owner-occupiers with 20% deposits.
Smaller lenders have followed suit. ME Bank confirmed a 0.25% increase effective 3 October, while ING, Macquarie and Suncorp have all updated their rate sheets to reflect the new environment.
Fixed vs Variable: The Great Debate
For borrowers weighing their options, the rate rises have reignited the fixed-versus-variable debate. Two-year fixed rates from the major banks currently sit between 6.29% and 6.34%, offering certainty but locking in a premium over today's lowest variable rates.
The gamble is whether the RBA has finished tightening. Some economists believe the October hike could be the last in this cycle, pointing to signs that inflation is finally trending back toward the target band. Others warn that a further increase early next year can't be ruled out if price pressures persist.
What Should Borrowers Do?
For existing variable-rate customers, the most immediate step is to check whether you're getting a competitive rate. ASIC research has found that existing Big Four customers typically pay 0.30% to 0.50% more than new customers at the same bank — a gap that can cost thousands over the life of a loan.
For those coming off a fixed rate in the coming months, the reality check will be significant. Many borrowers locked in rates below 3% during the pandemic and are now facing variable rates above 6%. Refinancing, negotiating with your current lender, or working with a broker to compare options across 90+ lenders can help soften the blow.
First home buyers haven't been spared either. While property prices have softened in some markets, the combination of higher rates and stricter serviceability requirements means borrowing power has shrunk considerably. A borrower who could access $800,000 at the start of 2025 may now find their ceiling closer to $650,000.
The Bottom Line
The 2026 rate rises are a reminder that the low-rate era is well and truly over. Whether you're an existing borrower, a refinancer, or a first home buyer, understanding your position and exploring your options has never been more important.
