If you’ve watched the news about the Reserve Bank of Australia this year and wondered what it actually means for your own mortgage, you’re not the only one asking. Perth borrowers have had three separate cash rate moves to make sense of in 2026. Here’s how that reaches your repayments, whether you’re on a variable or fixed rate, and when it’s worth reviewing your loan.
The Reserve Bank of Australia’s cash rate decisions directly influence variable home loan interest rates. When the RBA raises or lowers the cash rate, most lenders adjust their standard variable rates within days of the announcement. Lenders retain discretion over how much of any RBA rate movement they pass through to borrowers, so the full cash rate change is not always reflected in lending rates. Variable-rate borrowers see their monthly repayments change when rates move; borrowers on fixed-rate loans are unaffected until their fixed term expires. A rate change does not automatically make refinancing the right decision. Break costs on fixed-rate loans, current serviceability, and the gap between a borrower’s existing rate and available market rates all affect whether switching makes financial sense.
In plain terms: break costs are what a lender may charge you for ending a fixed-rate loan early, and serviceability is the lender’s assessment of whether your income comfortably covers the repayments.
How RBA Rate Decisions Flow Through to Perth Mortgages
The cash rate is the interest rate banks charge each other on overnight loans. As the RBA’s own explainer on monetary policy transmission describes it, the cash rate has a strong flow-on effect on other interest rates, including what banks pay on deposits and charge on loans, but that effect is indirect. The RBA doesn’t set mortgage rates directly. It moves the cash rate, and lenders then decide how much of that movement to pass on to their own standard variable rate (SVR), based on their funding costs and competitive position.
That’s why two borrowers on the same lender’s variable rate can still end up paying different amounts after a cash rate decision. It depends on your existing discount, how long you’ve been with that lender, and the specific product you’re on.
The same RBA explainer sets out the flow-on effect plainly: when rates fall, repayments on variable-rate mortgages fall too, freeing up cash for the household. The reverse applies when rates rise, usually from your next repayment date after the lender’s announcement.
What the 2026 Rate Cycle Means for Variable Rate Borrowers
2026 has been an active year for the cash rate. After cutting rates three times across 2025, the RBA reversed course:
| Meeting date | Change | Cash rate after |
|---|---|---|
| 4 February 2026 | +0.25% | 3.85% |
| 18 March 2026 | +0.25% | 4.10% |
| 6 May 2026 | +0.25% | 4.35% |
| 17 June 2026 | Held | 4.35% |
| 11 August 2026 | Held (unanimous) | 4.35% |
That’s three increases in under four months, followed by two holds in a row.
To put that in perspective, here’s an illustrative example only, on a $500,000 variable loan over a 30-year term:
| Rate | Monthly repayment | |
|---|---|---|
| Before the 2026 hikes | 6.00% | ~$2,998 |
| After the 2026 hikes | 6.75% | ~$3,243 |
| Difference | +0.75% | ~$245 a month |
This is a hypothetical example only. It assumes a starting rate that isn’t necessarily yours, a lender passing on the full 0.75% (not guaranteed, as covered above), and a standard 30-year principal and interest loan. Your own repayment change depends on your actual loan balance, rate, and how much of the increase your specific lender passed through, so treat this as a way to understand the scale of the impact, not a figure to expect on your own statement.
In its August statement, the RBA said financial conditions have tightened since the year’s rate rises and that the economy is slowing roughly as expected, but that inflation remains above target and isn’t expected to return to around the middle of the target range until late 2027. The Board also said it would raise the cash rate further if upside risks to inflation materialise.
For Perth borrowers on a variable rate, this means repayments on most variable loans have already moved higher across the year, following the three 2026 increases, and have held steady since May for those whose lender passed the changes through in full. If the RBA does hold rates for a sustained period, or cuts them at a future meeting, variable repayments could stabilise or ease. Neither outcome is guaranteed, and the Board has explicitly left the door open to a further increase if inflation doesn’t continue to moderate. Perth and wider Western Australian borrowers are best placed comparing their current rate against what other lenders are offering right now, rather than trying to time a future rate move.
What It Means for Fixed Rate Borrowers
If you’re on a fixed rate, none of the 2026 cash rate moves have changed your repayments directly. That’s the point of fixing. Your rate stays as agreed until your fixed term ends.
What matters is what happens at expiry. Most lenders automatically roll a fixed-rate loan onto their standard variable rate once the fixed term is up, and that rate is rarely their most competitive offer. If your fixed term is ending in the next few months, it’s worth reviewing your options 60–90 days out, rather than defaulting to whatever rate you’re rolled onto. New fixed rates being offered today are priced on where lenders expect the cash rate to go over the fixed period, not necessarily where it sits today, so a new fixed rate may look different again from the one you locked in previously.
Should You Review Your Loan When Rates Change?
A rate decision, on its own, isn’t a reason to act. It’s a reason to check. The same logic holds whether the RBA is hiking, holding, or eventually cutting rates: your mortgage strategy should come from comparing your actual numbers, not from guessing what the RBA will do next.
A few situations are commonly worth a closer look:
- Your fixed rate term is ending within 60–90 days. Most lenders roll an expired fixed loan onto their standard variable rate automatically, and it’s rarely their sharpest offer.
- You haven’t compared your rate to the market in the past 12 months. Lenders update their pricing regularly, so a competitive rate from last year may not still be one.
- The gap between your rate and current offers looks meaningful on your loan balance. Even a small difference adds up over a 25 or 30-year term.
- Your income, property value, or life circumstances have changed. A loan structure that suited you at settlement may not suit you now, on top of whatever the rate environment is doing.
None of these on their own guarantees that switching or restructuring will leave you better off. That depends on a full assessment of your circumstances, current serviceability, and the lender’s own criteria at the time. Discharge fees, application fees, and, for fixed loans, break costs all need to be weighed against any saving. Switching matters less if you’re staying in the loan for years, and more if you expect to sell or refinance again soon.

Frequently Asked Questions
What is the RBA cash rate right now?
As at 11 August 2026, the RBA cash rate target is 4.35%, following three 0.25 percentage point increases earlier in the year (February, March and May 2026) and two consecutive holds (June and August 2026). Rates can change at the RBA’s next scheduled meeting, so always verify the current rate with your lender or broker before making decisions.
How quickly do RBA rate changes affect my mortgage repayments?
For variable-rate loans, lenders typically announce whether they’re passing on a cash rate change within a few days of the RBA’s decision, with the change usually applying to your account from your next repayment date. Fixed-rate loans are unaffected until the fixed term expires.
What’s a good mortgage strategy if the RBA cuts interest rates?
If the RBA were to cut the cash rate at a future meeting, lenders could, but aren’t obliged to, reduce their variable rates, which may lower repayments for variable-rate borrowers. Fixed-rate borrowers wouldn’t see a change until their fixed term ends. As of August 2026, the RBA has been raising and then holding the cash rate, not cutting it, so a cut is a scenario worth planning for, not something already happening. The safest strategy either way is the same one this article recommends throughout: compare your actual rate against the market rather than trying to time the RBA.
Should I fix my rate now, or stay variable?
That depends on your budget’s sensitivity to further rate movements, how much flexibility you need (extra repayments, offset access, the ability to refinance without break costs), and your own view on the current rate environment. Our guide to fixed vs variable rates in Perth walks through the trade-offs in more detail.
Does an RBA rate hold mean rates won’t move again this year?
No. A hold means the Board left the cash rate unchanged at that particular meeting. It isn’t a commitment about future decisions. In its August 2026 statement, the RBA said it would raise the cash rate further if upside risks to inflation materialise, and that each decision is guided by the incoming data at the time. A future cut isn’t ruled out either, but as of August 2026 the RBA’s own stated position is specifically about the risk of further increases, not a signalled cut.
I don’t have a mortgage yet. Does the 2026 rate cycle affect how much I can borrow?
Yes, if you’re applying for a new loan rather than reviewing an existing one. Lenders assess how much you can borrow partly based on current interest rates, so a higher cash rate generally means a lower borrowing capacity than the same income would have supported a year or two ago. Our guides on how much you can borrow for your mortgage and getting pre-approval in Perth cover this in more detail.
Where This Leaves Perth Borrowers
The 2026 rate cycle has moved in a different direction than a lot of borrowers expected after 2025’s cuts. That’s the point. A loan structure that suited you last year isn’t guaranteed to suit you now.
