RBA Tuesday: Can your mortgage absorb $93?
The Reserve Bank of Australia lists the cash rate at 4.35%, effective from 17 June 2026, with the next update due at 2.30 pm Sydney time on Tuesday 11 August. The Monetary Policy Board meets on 10–11 August, and the August Statement on Monetary Policy will be released with the decision.
Forecasts are useful context, but they are not a mortgage plan. Before the announcement, the practical question is whether your household cash flow can absorb a change—and what you will do after your lender confirms the actual rate movement and effective date.
What is certain before Tuesday
The RBA sets the cash rate target. It strongly influences mortgage and deposit rates, but your loan rate is set by your lender and product terms.
The lender sets the pass-through. The amount passed on, the timing, the effective date and the revised minimum repayment can differ across lenders and products.
Your repayment depends on your loan. Balance, current rate, remaining term, repayment type, offset balance and product features all matter.
Worked example: test +0.25 percentage points
Assume a $600,000 balance, 25 years remaining and monthly principal-and-interest repayments. At 6.20%, the modelled repayment is about $3,939 a month. At 6.45%, it is about $4,033—a difference of roughly $93 a month.
This is a repayment stress test, not a forecast of Tuesday's decision and not a lender quote. It assumes the interest rate stays constant for the calculation and excludes fees, offset effects, redraw, repayment frequency and product-specific differences.
If the decision is a hold, increase or cut
Hold — your mortgage rate does not have to change simply because the cash rate is unchanged. Lenders can still adjust pricing for other reasons.
Increase or cut — do not assume the same amount or date applies to every loan. Check the lender notice, the effective date and the revised repayment shown for your account.
Before changing repayments — confirm whether you pay the minimum, a fixed nominated amount or an automatic transfer that may need manual adjustment.
Your weekend mortgage check
1. Confirm the inputs — actual balance, current rate, remaining term and principal-and-interest or interest-only status.
2. Test the buffer — model a small rate movement and ask whether the extra repayment would squeeze essential spending or emergency savings.
3. Read the lender notice — record the new rate, effective date, revised minimum and any action required.
4. Review structure fit — fixed, variable and split options should be assessed for repayment certainty, flexibility, fees and total cost—not chosen from one headline.
Tuesday check
Your Loan — use the balance, rate and remaining term from your own account, not an old approval or property estimate.
+0.25% Test — treat the result as a cash-flow scenario, not a prediction or recommendation.
Lender Notice — the amount and effective date turn a market decision into your actual repayment change.
Structure Fit — compare certainty, flexibility and total cost against how you expect to use the loan.
Bottom line
Tuesday's decision will be news. Your useful decision is to know the numbers before it arrives: what you owe, what you pay, how much buffer you have and when any lender change will actually affect your account.
