Sydney Interest Rates | Cash Rate Rises to 4.60% as Inflation Re-accelerates

The Reserve Bank increased the cash rate target by 25 basis points on 29 September, taking it to 4.60% from 30 September. The decision was unanimous and reflects the Board’s view that inflation remains too high.

For Sydney owners, the significance is broader than a higher mortgage repayment. The move affects holding costs, buyer borrowing capacity and the price range that different buyer groups can realistically support.

The latest inflation data remain uncomfortable

One day after the RBA decision, the ABS reported that annual CPI inflation rose to 4.0% in August from 3.5% in July. Trimmed mean inflation held at 3.6%.

The September rate decision was made before that public CPI release, so the new number should not be described as the reason for the 29 September decision. It is, however, the latest inflation evidence now available to owners and will form part of the information set before the next RBA meeting.

Why the RBA raised the cash rate

The RBA said recent inflation outcomes had been stronger than expected, with higher energy prices and domestic capacity pressures contributing to the outlook. The Board judged that further tightening was warranted to support a return of inflation to target.

The RBA said it would raise the cash rate again if needed. That is a conditional statement, not a forecast that another increase is certain.

What 4.60% means for an existing owner

The cash rate is not the mortgage rate. Each lender sets its own pricing and implementation date, while fixed-rate loans, offsets and repayment structures can produce different outcomes.

The practical review is therefore loan-by-loan:

• confirm the lender’s new rate and effective date;
• recalculate principal-and-interest or interest-only repayments;
• include strata, insurance, land tax, maintenance and compliance costs where relevant; and
• test whether the available cash reserve still covers vacancies, repairs and unexpected expenses.

As a simple interest-only illustration, 25 basis points is equivalent to $2,500 a year for each $1 million of debt, or about $208 a month, before fees and tax. Actual principal-and-interest repayments and lender pass-through will differ.

Most mortgagors remain resilient, but pressure is rising

The RBA’s October Financial Stability Review found that most Australian households with mortgages remain well placed to manage more difficult conditions, although pockets of stress exist. The RBA estimated that around 2% of variable-rate owner-occupier borrowers were experiencing a cash-flow shortfall in the first half of 2026, while the median mortgagor still held enough offset and redraw buffers to cover more than a year of scheduled mortgage payments at current rates.

The same review said less than 1% of borrowers were estimated to be in negative equity. For owners, that is an important distinction: higher repayments and softer prices create cash-flow pressure, but the RBA does not currently see widespread household balance-sheet distress.

Buyer borrowing capacity has contracted

Cotality estimated that the cumulative effect of the four rate rises since February had reduced borrowing capacity for a median household by almost $90,000, or approximately 9%.

That is an estimate based on a representative household, not an approval result for every buyer. For sellers, it still helps explain why genuine buyer depth may narrow quickly at higher price points. Campaign decisions should be based on contract requests, repeat inspections, written offers and current comparable evidence.

The next decision is on 3 November

The next Monetary Policy Board meeting is scheduled for 2–3 November, with the decision due at 2.30 pm AEDT on 3 November. Until then, owner strategy should work at today’s confirmed settings and remain viable without depending on a particular next move.
