The Reserve Bank has lifted the official cash rate by 25 basis points to 4.85%, its fifth increase of 2026 and the highest level since 2008. The decision, handed down on Melbourne Cup Day, was far from unanimous: six Board members voted for the hike while three preferred to hold at 4.60%. Notably, the Board has also dropped the "further increases if required" language that accompanied its last few statements.
What the RBA decided
This is the fifth cash rate rise of 2026, following earlier moves in February, March, May and September. Together they've added well over a full percentage point to borrowing costs this year, taking the cash rate to a level not seen since 2008, an 18-year high. More than 3.3 million Australian households with a home loan are affected.
Treasurer Jim Chalmers acknowledged the move was widely expected but said that doesn't make it any easier for families and businesses to absorb. Opposition leader Angus Taylor pointed out the cash rate is now higher than in any major advanced economy and the highest it's been since Kevin Rudd was prime minister, while the HIA warned the increase pushes the industry further from its home-building targets.
Why rates went up again
The RBA's reasoning centres on inflation proving stickier than hoped. Price pressures are elevated and broadly based, and the Bank's own inflation outlook has been revised materially higher. Higher fuel and commodity prices linked to the conflict in the Middle East, tighter domestic capacity than previously thought, and strong AI-related investment pushing up tech goods prices were all cited as contributors. The Bank nearly tripled its forecast for business investment growth in 2026, to around 12%, with AI and data-centre-related spending a key driver.
As a result, inflation is now not expected to return to the top of the RBA's 2-3% target band until late 2027, roughly nine months later than earlier forecasts. "We view the risks to the inflation outlook as still skewed to the upside," the Bank said.
At the same time, the broader economy is clearly slowing. The RBA expects growth of just 1.6% this year and 1.3% in 2027, well below trend. Unemployment, currently 4.7%, is forecast to rise toward 4.9% by the end of next year and above 5% in 2028, though employment is expected to stay positive. Housing prices have fallen significantly in what the RBA describes as one of the steepest downturns in 50 years, and global oil prices are expected to ease over the next 18 months but remain relatively elevated. Even so, the Bank sees no evidence the economy is headed for recession over the next two years.

At 4.85%, the cash rate target is now at its highest point since 2008, when it peaked at 7.25% before the Global Financial Crisis drove more than a decade of cuts to near-zero levels through 2020 and 2021. The sharp climb since 2022 marks one of the fastest tightening cycles in the RBA's history.
What it means for your mortgage
On a typical $700,000 variable loan, this hike alone adds roughly $107 a month to repayments, according to Canstar analysis, taking the total increase from this year's five hikes to around $532 a month on that loan size.
Using Caifu's own reference figure of a $600,000 variable loan over 25 years, this latest rise adds about $90 a month if passed on in full. Stacked across all five 2026 increases, that loan now costs roughly $450 more a month than it did at the start of the year, more than $5,400 annually.
What it means for property investors
A sixth rate rise in under twelve months reinforces a theme we've been flagging all year: the gap between investors with a tested plan and those without one keeps widening. A few things matter most right now.
- Stress-test at a higher rate. With the RBA's rhetoric less certain than before but inflation still running hot, build in headroom for at least one more possible move before you commit.
- Hold a genuine buffer. An offset account that can absorb a rate rise or two gives you options other buyers won't have if conditions tighten further.
- Focus on fundamentals. Population growth, infrastructure spending, employment hubs and constrained supply are what hold value through a cycle like this one, not short-term sentiment.
- Lean on rental yield. With holding costs rising again, strong and reliable rental demand matters more than ever to weekly cash flow.
- Revisit your existing loans. If you're already a borrower, this is a good moment to check your rate and structure against what else is available.
- Stay focused on the long term. Rate cycles move in both directions. Investors who buy well and hold through the cycle are consistently better placed than those trying to time the bottom.
The bottom line
A fifth rate rise in a year is a real cost to absorb, and we don't pretend otherwise. But markets that get harder also get less crowded, and that's exactly where a well-tested strategy pays off.
