RBA Rate Rise to 4.60%: What It Means for Your Mortgage Repayments

Here we go again. The Reserve Bank of Australia has lifted the official cash rate by another 25 basis points. That takes it to 4.60%, the fourth RBA cash rate hike this year. It is the highest the cash rate has sat since October 2011.

We have already had hikes in February, March and May. This one lands on households that have absorbed three increases in nine months. If you are on a variable loan, your lender will almost certainly pass it on. The only real questions are how much it costs you, and what you do next.

What the cash rate increase means for your home loan

The RBA raised the cash rate by 25 basis points to 4.60% on 29 September 2026. Take an owner-occupier with a $500,000 loan over 25 years, paying principal and interest. This move adds roughly $77 a month, or about $924 a year, if the lender passes on the full amount. Count all four hikes since February, and that borrower is paying around $3,696 a year more than they were in January.

That is the cost. What most people miss is that it is not fixed in stone. Osinski Finance has reviewed client loans through every move of this cycle from our Rockingham office. The borrowers who come out best are the ones who pick up the phone. They do not wait for the letter.

Why the RBA lifted rates for the fourth time this year

The RBA cash rate is the lever the Reserve Bank pulls when prices climb too fast. Lift it and borrowing gets more expensive. Households pull back, and demand comes out of the economy. It is a blunt instrument. Mortgage holders feel it first.

The Monetary Policy Board said in a statement that since the previous RBA meeting, some of the upside risks to inflation had been materialising.

"There have been further disruptions to global oil supply and recent data suggest that growth and inflation in Australia have been higher than expected," the statement said.

"Higher fuel prices have partially been passed through to prices of other goods and services. This inflation impulse is in addition to the effect of capacity pressures in the economy."

In plain terms: fuel got dearer. That flowed through to the price of almost everything else. On top of that, the economy was running hotter than the Board expected. Inflation is still sitting outside the inflation target range of 2 to 3%, which is the number the RBA is steering towards.

The Board has not ruled out another rise

This is the line worth reading twice. The rate hike pain for 2026 might not be over. The RBA has signalled another hike could come before too long if inflation does not return to target.

"The Board will continue to do what it considers necessary to bring inflation sustainably back to target, including increasing the cash rate target further if needed," the RBA statement said.

Plan your budget around that possibility. Do not just hope it misses you.

How much more will your mortgage cost?

Unless you are on a fixed rate, your bank will likely follow the RBA's lead. Expect an increase on your variable rate mortgage within weeks.

Here is what this month's 25 basis point move does to minimum monthly repayments. The last column shows what all four 2026 hikes have done together.

These figures assume an owner-occupier on a 25-year loan paying principal and interest. They also assume the lender passes on the full 25 basis point increase. Some lenders pass on less. Some take longer to do it. Check your own lender's announcement rather than assuming.

The monthly number is the one that stings. The annual column is the one that changes behaviour. An extra $3,696 a year is a holiday, a school fee bill, or a decent emergency fund.

What if you are on a fixed rate?

Nothing changes today. A fixed rate is locked for the length of the fixed term. This decision does not touch it.

The issue is what you roll onto when that term ends. If your fixed period expires within twelve months, run the numbers on the revert rate now. Do not leave it until the week it happens. Our fixed rate home loan page covers how fixing works and when it suits. We have also written on fixed rate versus variable if you are weighing up a split.

When will the increase actually hit your repayments?

Two separate things happen to your mortgage repayments. They happen at different times.

First, your lender starts charging the higher interest rate. That usually takes effect within one to three weeks of the RBA decision.

Second, your lender changes your minimum repayment and your direct debit. That comes later, and it comes with written notice. Expect somewhere around 20 to 30 days, depending on the lender. Where you sit in your billing cycle can push it out further. It is not unusual for the change to land two or three months after the announcement.

The gap between those two events catches people out. Interest accrues at the higher rate well before the payment moves. So the account looks unchanged while the loan quietly costs more. We covered that lag in more detail in how long it takes for an interest rate rise to kick in.

What if your repayment does not change at all?

Plenty of borrowers will open their banking app next month and see the same number. That is not a lender oversight. It is not good news either.

When rates fell through 2025, many borrowers left their repayments where they were. They did not drop to the new minimum. Those people have been paying above the required amount ever since. That leaves a cushion between their actual payment and their minimum. A cash rate increase of this size may not be enough to close the gap.

What changes is the split. More of that same payment now goes to interest. Less goes to the loan balance. The cushion shrinks, and the loan slows down. The cost is real. It has just moved from your monthly budget to your loan term.

How to check where you actually stand

Open your latest loan statement or your online banking. Look for two figures: your current minimum repayment, and the interest charged last period against the amount that came off the principal. If your payment sits comfortably above the minimum, you have room. If the two numbers are converging, your repayment is next.

What you can do about it right now

This latest RBA hike is another tough pill to swallow for mortgage holders on a variable rate. It hurts. There are still steps you could take to help offset it.

The worst option is doing nothing. Everything below is worth a conversation.

Ask your current lender for a rate review

Variable rates are negotiable. Lenders routinely hold better pricing for customers who ask. Ring them, ask what they can do on your rate, and say plainly that you are comparing.

The arithmetic here is the motivating part. Knock 0.25 percentage points off your current rate, and you have cancelled out this rise entirely. Half a percentage point covers you for the next one too.

Refinance to a more competitive lender

If your lender will not move, someone else will. Switching usually takes a few weeks. It involves a fresh application, a valuation, and discharge and establishment costs to weigh against the savings.

It is not automatically the right call. On a smaller balance, or with a fixed break cost in play, the maths sometimes says stay. That is the calculation we run before recommending anything. Our refinancing page sets out what the process involves.

Switch to interest-only for a period

Paying interest only for a set period lowers the immediate payment. It frees up cash flow quickly. The trade-off is that the balance does not reduce while you do it. Repayments then step up afterwards to make up the ground.

It is a sensible short-term measure for a specific situation. It is not a default setting.

Consolidate other debts

Rolling higher-rate personal or card debt into the home loan can ease monthly pressure. The catch is the term. Stretching short-term debt over 25 years can cost more in total interest, even at a lower rate. It needs a plan to pay the consolidated portion down faster.

Restructure or split the loan

Splitting the loan gives you part fixed and part variable. You get certainty on one portion and flexibility on the other. It suits borrowers who want to cap their downside without locking the whole thing in.

Every household is unique, and we are committed to helping you find a solution that fits your needs.

How to soften the blow of the next rise

The Board has said outright that it will go further if it has to. Building in some protection now is a reasonable response, not a pessimistic one.

Build a buffer

Money in an offset account reduces the balance interest is charged on, dollar for dollar. It also stays available if you need it. A redraw does a similar job with less flexibility. Australians have been pouring money into offsets for exactly this reason, something we looked at in why offset accounts are hitting new highs.

Keep repayments above the minimum

If your budget allows it, hold your repayment where it is. Do not drop to each new minimum. Every dollar above the minimum is both a faster payoff and a cushion against the next move.

Stress-test your budget now

Work out what your repayment becomes after one more hike, then after two. If those numbers do not fit, you want to know this month. Six months from now is too late. Each interest rate rise in Australia compounds on the last, and the fourth always lands harder than the first.

Review the loan on a schedule

Most borrowers on an uncompetitive rate are there because nobody has looked at the loan in years. It is rarely a bad original choice. Keep an eye on where the market sits, through something like our interest rate tracker. That is the difference between reacting and being ready.

If you are buying or holding a pre-approval

Rate rises reduce borrowing capacity. Lenders assess your application against a serviceability buffer on top of the actual rate. When the rate moves, the maximum they will lend moves with it.

That matters if your pre-approval was issued before today. The figure on it was calculated under the old assumptions. It may no longer reflect what a lender will approve. Get it reviewed before you bid on anything. We have written about how a pre-approval can quietly go out of date and what to do about it.

What this interest rate rise in Australia means for Perth & WA borrowers

Every national headline about this decision is written around Sydney and Melbourne loan sizes. Those numbers do not describe most WA households. A borrower with a smaller balance faces a smaller dollar increase than the figures quoted on the news tonight. Worth remembering before you panic about a number that was never yours.

That does not make it painless. It does mean the response is different. On a smaller loan, a 0.25 reduction from your lender covers proportionally more ground. The case for a review gets stronger, not weaker. We work with households across Rockingham, Baldivis, Kwinana, Secret Harbour and the surrounding suburbs. The loans we see locally respond well to exactly this kind of tidy-up. Our mortgage brokers in Rockingham can walk through yours.

Key Takeaways

• The RBA lifted the cash rate 25 basis points to 4.60% on 29 September 2026. It is the fourth increase this year and the highest level since October 2011.
• A $500,000 owner-occupier loan over 25 years costs roughly $77 a month more. Across all four 2026 hikes, that is about $3,696 a year.
• Your lender applies the higher rate within one to three weeks. Your minimum repayment usually changes later, with around 20 to 30 days' written notice.
• If your repayment does not change, you are likely paying above the minimum already. More of that payment now goes to interest, so the loan slows down instead of the budget tightening.
• A 0.25 percentage point reduction from your lender cancels out this rise entirely. That makes a rate review the highest-value phone call you can make this week.
• The Monetary Policy Board has said it will raise again if inflation does not return to target. Budget for that possibility.

Frequently Asked Questions About the RBA Rate Rise

How many times has the RBA raised rates in 2026?

Four times: February, March, May and September. Each move was 25 basis points, taking the cash rate to 4.60%. For a borrower with a $500,000 loan, those four increases add up to roughly $3,696 a year. It is the compounding that has made this year difficult, not any single decision.

What is the RBA cash rate right now?

The RBA rate target is 4.60%. That follows the Monetary Policy Board's decision on 29 September 2026. It is a 25 basis point increase on the previous target of 4.35%, and the highest the cash rate has been since October 2011. The Board meets eight times a year, so the next chance for a change is at its following scheduled meeting.

Will my bank pass on the full rate rise?

Most lenders pass the full increase on to variable rate customers. The major banks usually announce within a few days of the decision. Some pass on only part of it, and a few hold off longer than others. Do not assume, and do not rely on a news summary. Check your own lender's announcement, or ask us and we will check it for you.

How much will my mortgage go up after this rate rise?

On a $500,000 loan over 25 years with full pass-through, roughly $77 a month. A $750,000 loan goes up to around $115 a month. A $1 million loan goes up to around $154 a month. Those figures assume principal and interest repayments and a 25-year remaining term, so your own number will differ. The table earlier in this article shows the annual impact alongside the monthly one.

When will my repayments actually increase?

Your lender will typically start charging the higher rate within one to three weeks. The change to your minimum repayment and direct debit comes later, with written notice of around 20 to 30 days. Depending on your billing cycle, the actual change can take two or three months to appear. Interest accrues at the higher rate throughout, so the cost starts before the payment moves.

Does a rate rise affect fixed rate home loans?

Not during the fixed term. A fixed rate is locked regardless of what the RBA does. That certainty is what you paid for when you fixed. The impact lands when the fixed period ends and the loan reverts to a variable rate, which can be a significant jump. If your fixed term ends within the next year, start looking at your options now.

Can I negotiate a lower rate with my current lender?

Yes, and more people should. Variable rates are negotiable. Lenders commonly hold retention pricing for customers who ring and ask, especially those who mention they are comparing. A reduction of 0.25 percentage points offsets this rise completely, and 0.50 protects you against another. If your lender will not move, that tells you something useful about whether to stay.

Is now a good time to refinance?

It depends on your current rate, your loan balance, your equity, and how long you plan to stay. Refinancing carries discharge fees, application costs, and sometimes a valuation. On a smaller balance, those can eat the savings. We compare your existing rate against what is genuinely available to someone in your position, cost the switch properly, and give you the net result. Sometimes the answer is that staying and negotiating is the better move.

Will the RBA raise the cash rate again?

The Board has said it will do what it considers necessary to bring inflation back to target, including raising further if needed. That is guidance, not a forecast. Nobody can tell you with certainty what the next meeting brings. Work out what one or two more increases would cost you, and make sure your budget can absorb it; if it cannot, address that now.

What should I do if I cannot afford my repayments?

Contact your lender before you miss a payment, not after. Every lender has a hardship team and formal arrangements available. Those include temporary payment reductions, interest-only periods and loan term extensions. Reaching out early gives you more options than waiting does. Free, independent financial counselling is available through the National Debt Helpline on 1800 007 007, and Moneysmart lists further support services.
