On 11 August 2026 the Reserve Bank of Australia left the cash rate target at 4.35 per cent, the level it has held since late 2023. The decision was unanimous, and the Board went out of its way to say the door to further increases stays open while inflation runs above its 2 to 3 per cent target. For anyone shopping for a car, the natural question is simple: if the official rate is not moving, why do car loan rates keep sitting so much higher, and why do they barely flinch when the RBA holds?
The short answer is that the cash rate is only one ingredient in the price of a car loan, and often not the largest one. Here is how the gap actually works, and what you can control.
What the cash rate actually sets
The cash rate is the interest banks pay to borrow from each other overnight. It flows through to the funding costs lenders face, so it forms a floor under every loan in the country. When it rises, funding gets dearer and rates drift up. When it holds, that pressure simply stops building. What the cash rate does not do is set the retail price of a secured car loan directly. Between the 4.35 per cent cash rate and the rate on your contract sits a stack of other costs and margins.
Why car loan rates sit well above 4.35 per cent
Look at what lenders publish today and the gap is obvious. Secured car loan rates on our panel commonly run from around 7 per cent to 13 per cent per annum, with comparison rates higher again once fees are counted. Several things drive that spread:
- Risk margin. A car loan is only partly secured by a depreciating asset, so lenders price in the chance of default and the shortfall if a car has to be sold.
- Term. Car loans run three to seven years. The longer the money is out, the more a lender charges to cover uncertainty over that period.
- The asset. A near new car is cheaper to finance than an ageing one, because the security holds its value better. Rates climb as the vehicle gets older.
- Fees. Establishment and monthly account fees lift the comparison rate above the headline number, which is why the comparison rate is the figure to watch.
- Your profile. Credit history, income stability and deposit size move your personal rate within the advertised band.
None of those move just because the RBA holds. That is why a hold rarely translates into a cheaper car loan on its own.
A hold is not a cut
It is easy to read a steady cash rate as good news for borrowers. In practice a hold means the current level of pressure stays exactly where it is. With the Board signalling that its next move could still be up rather than down, lenders have little reason to trim car loan margins in the near term. The next scheduled decision lands on 28 and 29 September 2026, and the RBA has been clear that inflation remaining above target keeps a further rise on the table.
What you can actually control
You cannot move the cash rate, but you can move most of the other ingredients:
- Compare the comparison rate, not the headline. Two loans with the same advertised rate can cost very differently once fees are in. Our car loan rates page and the comparison rate guide explain how to read them.
- Shorten the term where the repayment still fits. A shorter loan usually carries a lower rate and far less total interest. A repayment calculator shows the trade off in dollars.
- Tidy your credit file before you apply. Your rate sits inside the advertised band, and where you land depends heavily on your record. Our guide on your credit score and your car loan rate covers the levers.
- Revisit an old loan. If you signed near the top of the rate cycle, refinancing can reset the rate even while the cash rate holds. See how refinancing works.
- Shop more than one lender. Rates and fees vary widely across the market. Comparing lenders side by side is the fastest way to see the real spread.
The takeaway
A steady 4.35 per cent cash rate is the backdrop, not the whole story. Car loan pricing is built mostly from risk, term, the age of the car and the fees attached, then adjusted for who you are as a borrower. Waiting for the RBA to move is unlikely to shift your rate much, and with the next decision potentially an increase, the borrower who compares carefully and applies with a clean file today is usually better placed than the one holding out for a cut that may not come.
