Every Reserve Bank of Australia cash rate decision prompts the same question from borrowers: what does this mean for my home loan? The answer depends on your loan type and your lender. Here is how a cash rate move reaches a variable rate, what fixed-rate borrowers should watch, and when a review is worth your time.
Where the cash rate sits right now
As at 4 October 2026, the RBA’s published cash rate target is 4.60 per cent. The Monetary Policy Board announced a 0.25 percentage point increase on 29 September 2026, effective 30 September 2026. It was the fourth increase of 2026: the Board also lifted the target by 0.25 percentage points in February, March and May, and held it steady in June and August. The Board’s next scheduled meeting is 2 to 3 November 2026. Figures like these move, so check the RBA’s cash rate page for the latest position.
How a cash rate move flows through to variable rates
The cash rate is the interest rate on overnight loans between banks. It is not your mortgage rate, but it shapes what lenders pay to fund the money they lend. When it changes, lenders review their own variable rates, and most announce a change within days. In practice:
- Lenders decide, not the RBA. A 0.25 percentage point move may be passed on in full, in part or, occasionally, not at all. Lenders also move rates outside the RBA cycle when their funding costs shift.
- There is a lag. A lender’s announcement usually takes effect for existing customers one to three weeks later, and the minimum repayment often changes at a later repayment cycle again. Read your lender’s notice for the exact dates.
- New and existing customers can be treated differently. The advertised rate for new borrowers is not necessarily what an existing customer pays, and the gap can widen over time without you noticing.
- Your repayment may not change on its own. Some lenders adjust the minimum repayment when rates fall; others leave it where it is unless you ask, which pays the loan down faster.
The dollar impact depends on your balance, rate and remaining term, and our calculators let you test different rates against your own loan.
What fixed-rate borrowers should watch
If your rate is fixed, a cash rate decision does not change your repayments during the fixed period. The risks sit at the edges of the term:
- The expiry date. When a fixed term ends, most loans roll onto the lender’s standard variable rate, which is often higher than other rates the same lender offers. Note the date and start the conversation two to three months out.
- Fixed rates on offer move early. Lenders price new fixed terms off longer-term funding markets, which react to where the cash rate is expected to go rather than where it is today. Fixed rates often change before or between RBA decisions, so a quote from last month may no longer be available.
- Break costs. Exiting a fixed loan early can attract a break cost, which depends on how rates have moved since you fixed and how long is left. Ask your lender for a written quote before deciding to refinance a fixed loan.
When a home loan review makes sense
You do not need to wait for an RBA announcement, and a single decision is rarely a reason on its own. A review is usually worthwhile when one of these applies:
- Your fixed term ends within the next six months.
- You have not compared your variable rate with the market in two or more years.
- Repayments feel tight, or your income, household or property value has changed since you took out the loan.
- You are paying for features such as an offset account or a package fee that you do not use, or you want features your current loan lacks.
- You want to restructure, for example consolidating debt or accessing equity for a suitable purpose.
A review does not have to end in a new loan; sometimes the right step is asking your existing lender to reprice. Where refinancing does make sense, weigh the costs: discharge and government fees, any application or valuation fees with the new lender, and lenders mortgage insurance if the loan sits above 80 per cent of the property’s value. The new lender assesses your application against its own current criteria, including a serviceability buffer above the actual rate, so approval is the lender’s decision and should never be assumed.
