Three Major Banks Now Tip RBA Rate Hike in September
National Australia Bank, Deutsche Bank and UBS are all forecasting the RBA will lift the cash rate to 4.60% on 29 September 2026.
Banks lining up behind a September rate rise
As of Friday 4 September 2026, three major financial institutions — National Australia Bank, Deutsche Bank, and UBS — are all expecting the Reserve Bank of Australia to hike the cash rate at its 29 September board meeting. If the RBA acts, the cash rate would move to 4.60%, according to ABC News.
UBS was the latest to shift its forecast on Friday, citing inflation that remains "too high" as the primary driver. The bank also flagged the global backdrop: an economic environment "led by an AI/trade cycle boom" is now generating global inflation pressure, raising the risk that central banks in other countries will also hike rates. When major economies move together on monetary policy, it limits the RBA's room to stay on hold.
National Australia Bank and Deutsche Bank had already moved to a September hike call before UBS joined them on Friday — a notable consolidation of expert opinion in a short space of time.
What the Treasurer is — and isn't — saying
Treasurer Jim Chalmers was asked directly on ABC News Breakfast on Friday whether the economy needed further rate rises to stamp out excess inflation. His answer was carefully worded.
"I'm not going to give free advice to the independent Reserve Bank," Mr Chalmers said. "I think it's self-evident that the interest rate rises in the system already are putting additional pressure on people."
He acknowledged the rate rises already delivered are still feeding through the economy — pointing to the national accounts as evidence — but declined to say whether more hikes were needed. For borrowers, the message is that the government is watching household stress carefully, even as the central bank considers adding to it.
The Australian dollar climbed to a four-month high of 72.15 US cents during Friday's trading session before settling back to around 72 US cents. A firming currency is often read as the market pricing in higher rates ahead — another signal that traders are treating a September hike as the base case, not a tail risk.
AMP flagged a significant concern: two further hikes from current levels would risk serious damage to the economy. While the current consensus among banks is focused on a single September move, the combination of domestic inflation and global rate pressure means additional moves later in the year remain a live possibility for borrowers to plan around.
What this means for your home loan
If the RBA lifts rates on 29 September, variable-rate borrowers will feel the effect within weeks. Most lenders pass on official rate changes quickly, typically within a few weeks of the board decision.
The cumulative impact of this rate cycle is already significant. Every additional increase compounds what households are already managing. If you haven't reviewed your home loan in the last six to twelve months, you may be sitting on a back-book rate — a rate your lender no longer offers to new customers — and paying more than you need to. Our refinance savings calculator can show you whether switching would save money, even in a rising-rate environment.
For first home buyers who have pre-approval in hand, it is worth confirming with your broker that your approval holds at a cash rate of 4.60%. Some pre-approvals are based on rate assumptions that may need to be updated before the September decision.
What you should do before 29 September
The weeks between now and the September board meeting are valuable preparation time. Here is where to focus:
**Review your current rate.** Many borrowers are paying a rate set months or years ago that has not been renegotiated. A broker conversation can quickly identify whether you are competitive with what is available today. Even in a rate-rising environment, the spread between the most and least competitive lenders remains meaningful.
**Understand your serviceability position.** Lenders assess your ability to repay at a rate above your actual loan rate. As the cash rate moves toward 4.60%, it is worth understanding how your current borrowing sits against that ceiling — particularly if you are thinking about taking on additional debt or purchasing another property.
**Think through your fixed-rate options.** Markets have already priced in the September hike, which means fixed rates from most lenders have moved accordingly. Fixing provides repayment certainty but comes with break costs if your circumstances change. A split structure — part variable, part fixed — can offer a practical middle ground for borrowers who want some predictability without fully giving up flexibility.
**Check your borrowing power if you are about to buy.** A rate rise between now and settlement can affect the maximum loan size a lender will approve. Running the numbers now, before any move, gives you a clearer picture of where you stand.
The cheapest home loans currently available are still priced below the market average. Whether you are looking to refinance or are actively in the market to buy, that gap is worth exploring before the RBA narrows the field further.
Do not wait for the announcement on 29 September to start asking questions. The banks putting their forecasts behind a September move have put real weight behind the call. Getting positioned before the decision — not after — is almost always the stronger approach for borrowers.
