The RBA rate rise announced on 29 September 2026 takes the cash rate target from 4.35% to 4.60%, an increase of 0.25 percentage points, or 25 basis points. The new target takes effect on 30 September 2026. For car buyers, the immediate task is to check their actual loan terms, rather than assume their quoted rate has changed by the same amount.
The decision was unanimous. In its September monetary policy statement, the Reserve Bank said inflation remained too high and pointed to energy costs and pressure on domestic capacity. It left open the possibility of further increases if needed. That is a conditional position, not a promise of another rise.
The RBA rate rise at a glance
- Previous cash rate target: 4.35%.
- New announced target: 4.60%.
- Increase: 25 basis points.
- Effective date: 30 September 2026.
- Next scheduled decision: 3 November 2026.
The effective date and next update are listed on the RBA cash rate overview. The announced target applies to overnight lending between banks. It is not a car-loan interest rate or a personalised finance quote.
If your car loan is already fixed
A fixed-rate car loan does not become a variable-rate loan because the RBA announces a rise. Its agreed interest rate and scheduled repayments remain governed by the contract. ASIC's Moneysmart explanation of fixed and variable loans describes how fixed repayments provide certainty, while variable repayments can move when interest rates change.
Start with the loan contract or latest statement and identify the rate type. If you cannot tell whether your loan is fixed or variable, ask the lender before changing your budget. A news headline is not a notice that your direct debit has changed. Keep making the agreed repayments unless the lender gives you updated instructions.
This distinction also matters if you are partway through buying a car. A quote, an application and a settled loan are different stages. Ask which terms apply to your stage and whether anything still needs to be confirmed before settlement.
If you are comparing a new car loan
There is no single car-finance rate that automatically becomes 4.60%. The offer depends on the lender and the application. Moneysmart's car-loan guide explains that loan features, the term, credit history and the vehicle can affect pricing. Compare the complete offer rather than treating the RBA announcement as a price list.
For a useful comparison, keep the proposed amount, term and any balloon payment consistent between quotes. Ask for the interest rate, comparison rate, repayment schedule and fees together. The comparison rate is a useful guide to interest and most fees under stated assumptions; the written costs for your own loan still matter.
Our car-loan rates guide explains the comparison process, and the lender directory provides product context. Neither replaces an assessment of the particular borrower, vehicle and finance request.
Questions to ask about an existing quote
If you received a quote before the announcement, ask the provider to confirm its status in writing. Do not assume it has expired, but do not assume it is locked either. A short message can resolve the practical uncertainty:
- Is the quoted rate still available for this application?
- What is the expiry date, and does it refer to acceptance or settlement?
- Are any documents or conditions still outstanding?
- Have the fees, repayment amount or balloon changed?
- Can I have the current offer in writing before I commit?
Keep the response with the quote. That gives you a clear record of what was offered and when, instead of trying to reconstruct a phone conversation later. If the lender supplies revised terms, compare the entire new document with the earlier version. A headline rate is only one field in that comparison.
Check the household budget, not just the car repayment
A fixed car repayment can stay unchanged while other household costs increase. Review your actual bank transactions and current bills before deciding how much room there is for a new commitment. Include costs paid less frequently, such as registration, insurance and servicing, as well as regular fuel or charging expenses.
Use the Loanseekers repayment calculator to explore the amount and term you are considering. Enter a lender's quoted rate rather than the RBA cash rate, and read the calculator assumptions. Treat the result as an estimate to compare with the lender's written repayment schedule, not as an offer of finance.
If you change the loan term to make a repayment smaller, look at the overall cost too. A lower regular payment can come from taking longer to repay the debt. It does not, on its own, show that the loan is cheaper. Our guide to car-loan fees helps identify costs that can otherwise get lost in a repayment-only comparison.
Refinancing needs its own calculation
Today's announcement is not evidence that switching loans will save money. Moneysmart's refinancing guidance warns that fees and a longer repayment term can outweigh the benefit of a lower rate. Compare what remains payable on the existing loan with the complete cost of the proposed replacement.
That comparison starts with a current payout figure, any early repayment costs, the new loan's fees and its end date. Keep the remaining term visible alongside any longer alternative. Our refinance information explains the process, but whether a switch is worthwhile depends on the actual figures and circumstances.
What to watch next
The RBA's decision and a lender's pricing notice answer different questions. The first sets monetary policy; the second tells you what a particular provider is changing. For an existing variable loan, check the lender's notice for the new rate, repayment and start date. For a new application, ask for the current offer and its conditions.
There is no need to turn the announcement into a rushed car purchase. Use it as a prompt to check information that can be verified now: your rate type, the validity of your quote, the complete borrowing cost and the room in your budget. Those checks remain useful regardless of the next RBA decision.
