Australia’s Cash Rate Is Now 4.6% — Where Will Households Feel It Most?
Australia’s cash rate is now 4.60%, but for many households the more useful question is not simply how high the rate has gone. It is where the extra cost will begin showing up in the household budget from October.
The Reserve Bank of Australia raised the cash rate by 0.25 percentage points at its September meeting, taking it from 4.35% to 4.60%. The new cash rate took effect on 30 September 2026.
For mortgage holders, however, the impact does not necessarily begin on the same day as the RBA change. Australia’s Big Four banks have announced a 0.25 percentage point increase to variable home loan rates from 9 October 2026.
Why Did Australia’s Cash Rate Rise to 4.6%?
Inflation remains elevated, prompting the RBA to raise the cash rate by 0.25 percentage points to 4.60%.
The RBA said inflation remained too high and that some of the upside risks it had previously identified were materialising. It pointed to pressure on domestic capacity as well as higher global energy prices associated with the conflict in the Middle East. Recent Australian inflation outcomes had also been stronger than expected at the previous meeting.
The September increase follows earlier rate rises in 2026 and brings the cash rate back to a level Australia has not seen since 2011.
When Will the Latest Rate Rise Hit Home Loans?
For Big Four variable-rate mortgage customers, the latest 0.25 percentage point increase takes effect from 9 October 2026.
Commonwealth Bank, Westpac, NAB and ANZ have each announced a 0.25 percentage point increase to variable home loan rates from 9 October.
This timing matters. The RBA cash rate became 4.60% on 30 September, but a borrower’s mortgage rate changes according to the effective date set by their lender.
Fixed-rate borrowers generally will not see their existing fixed interest rate change immediately. What happens when the fixed period ends will depend on the loan agreement and the rates available at that time.
How Much Could a 0.25% Rate Rise Add to a Mortgage?
For a large mortgage, a 0.25 percentage point increase can add more than $100 a month to repayments.
To make the change easier to visualise, the examples below use the same assumptions: principal-and-interest repayments, 25 years remaining and an interest rate moving from 6.00% to 6.25%.
| Loan balance | At 6.00% | At 6.25% | Extra / month |
|---|---|---|---|
| $500,000 | $3,222 | $3,298 | +$77 |
| $750,000 | $4,832 | $4,948 | +$115 |
| $1,000,000 | $6,443 | $6,597 | +$154 |
Illustrative calculation only. Assumes principal-and-interest repayments, 25 years remaining and an interest rate change from 6.00% to 6.25%. Actual repayments depend on your loan balance, interest rate, remaining term, repayment type and lender.
The headline increase may look small at 0.25 percentage points, but the dollar impact grows with the size of the mortgage. Repeated rate changes can also accumulate, which is why checking the actual repayment amount matters more to a household budget than looking at the cash rate alone.
Why Does 4.6% Feel Harder Than It Did in 2011?
The cash rate alone cannot tell us how much pressure a household is under because mortgage balances, housing costs and household expenses also matter.
The current 4.60% cash rate takes Australia back into territory last seen in 2011. In fact, the cash rate was 4.75% for much of 2011 before the RBA reduced it to 4.50% in November of that year.
That makes a simple “4.6% now versus 2011” comparison incomplete. The dollar amount borrowed matters enormously: the same interest-rate movement applied to a larger mortgage produces a larger dollar change in repayments.
Households also make mortgage payments alongside groceries, insurance, utilities, transport and other living expenses. The practical question in 2026 is therefore not whether 4.6% sounds historically high or low in isolation, but how much disposable income remains after today’s housing and essential costs are paid.
What About Renters and Households Without a Mortgage?
Renters do not receive a mortgage repayment increase when the RBA raises rates, but higher interest rates can still affect the wider household economy.
It is important not to assume that an RBA rate increase automatically produces an immediate rent increase. Rental prices are influenced by multiple factors, including local supply and demand, vacancy rates, property costs and individual tenancy arrangements.
Higher interest rates are designed more broadly to reduce demand in the economy by making borrowing more expensive and encouraging households and businesses to moderate spending.
There can also be another side to higher rates. Some savers may benefit when banks increase rates on eligible savings or deposit products. The impact of a 4.60% cash rate is therefore not identical for every Australian household.
What Should Australian Households Check Now?
The first step is to find out whether your own loan will change, when the new rate applies and what that means in actual dollars.
- Check whether your mortgage is variable or fixed.
- Check your lender’s effective date rather than assuming the RBA announcement date is your repayment-change date.
- Find your current mortgage interest rate in your banking app or latest loan statement.
- Calculate your new repayment using your actual balance and remaining loan term.
- Update the household budget using the new repayment amount.
- Ask your existing lender for a rate review if you want to check whether a different rate may be available for your loan.
Refinancing is not automatically the right response to a rate rise. Fees, loan features, remaining term, eligibility and the rate actually offered all matter. But another rate increase is a useful prompt to check what you are currently paying before making any decision.
Is another RBA rate rise coming?
The next RBA decision cannot be known in advance. The cash rate is currently 4.60%, and the next Monetary Policy Board meeting is scheduled for 2–3 November 2026, with the decision due on 3 November 2026. Future decisions will depend on incoming economic data and the RBA’s assessment of inflation and economic conditions.
For Australian households, the most useful number this October may therefore not be 4.60% itself. It may be the new repayment appearing in the banking app — and how much room that leaves in the monthly household budget.
Cash rate: The interest rate targeted by the Reserve Bank of Australia in the overnight money market. It influences other interest rates, including mortgage and deposit rates.
Basis point (bp): One hundredth of a percentage point. A 25-basis-point increase equals 0.25 percentage points.
Variable home loan: A mortgage where the interest rate can change over time.
Fixed home loan: A mortgage where the interest rate is fixed for an agreed period.
Principal and interest: Repayments that pay down both the amount borrowed and the interest charged on the loan.
