Reserve Bank Governor Michele Bullock said in Canberra on Friday that the cash rate may not yet be high enough to bring inflation back to target, and markets moved to price a 93% chance of a rise on 29 September. Lenders had already started acting. Nine lenders lifted fixed rates in the first half of September, including two of the major banks, and the cheapest fixed rates at the big four now start at 6.34%. For anyone deciding whether to fix, the window on current pricing is closing quickly.

What Did Michele Bullock Say About Interest Rates This Week?

Speaking at Parliament House in Canberra on Friday, Governor Michele Bullock said “some of these upside risks to inflation appear to be materialising,” even as economic growth slows Australian Broker. Asked whether the current 4.35% cash rate is restrictive enough to return inflation to target, she said: “It may be that it is not, and that is really where we are at the moment.”

Bullock pointed to the Middle East conflict, saying oil and related prices “have increased sharply again and will add directly to inflation,” and to the global boom in artificial intelligence investment, which is lifting demand in key supply-chain economies. Futures markets priced a 93% probability of a rate rise at the 28 to 29 September meeting by the end of the day, up from 54% at the start of the month.

Why Are Fixed Home Loan Rates Rising Before the RBA Decides?

NAB lifted its fixed rates by 0.15 percentage points across one to five-year terms this week, taking its one-year rate from 6.44% to 6.59%, while ANZ raised its two-year fixed rate by 0.20 percentage points to 6.49% Australian Broker. ING raised fixed rates by 0.20 percentage points on 16 September, and Macquarie made a similar move the week before, leaving both with lowest fixed rates of 6.39%. Further increases from other lenders have already been announced for next week.

Fixed rates are priced off wholesale funding costs and market expectations for the cash rate over the fixed term, so they tend to move ahead of the RBA. Fixing remains a minority choice. One major bank reported only 7% of its new lending went to fixed rate products in the six months to June, and most lenders’ lowest advertised rates are variable.

Is it too late to lock in a fixed rate before the RBA decision?

Fixed rates are set by each lender and can change at any time, so the rate on offer when you apply is not guaranteed until the loan settles. Some lenders offer a rate lock for a fee, which holds the fixed rate quoted at application for a set period. Whether fixing suits you depends on how much you value repayment certainty against the flexibility of a variable loan, and the comparison is worth running with current rates from several lenders.

What Does APRA’s Latest Data Say About Borrower Stress?

Lending with deposits of 5% or less reached a record 4.31% of new owner-occupier loans, reflecting the uncapped Home Guarantee Scheme. Interest-only loans rose to 24% of new lending from 21% a year earlier, and $11.6 billion of new loans, or 5.8%, were approved as exceptions to standard serviceability policy for refinancing borrowers, a record. That exception pathway lets some borrowers switch to a cheaper loan even if they would not pass a full serviceability test today.
