CBA has today hiked fixed rates for its owner-occupier and investor loans for new customers, with increases of up to 0.48 percentage points.

This is almost two times a standard 0.25 RBA hike on the bank’s lowest 2-year fixed rate, just seven days out from the next central bank cash rate decision.

The changes follow similar moves by Westpac, NAB, and ANZ last week, which saw increases of up to 0.20 percentage points. 

As a result, the lowest fixed rate available from a big four bank is now 6.49%, for a 1-year term from ANZ, and a 2-year term, from both NAB and ANZ.

Seven lenders still have a fixed rate starting with a 5

While the majors’ fixed rates are largely now above 6.50%, and in some cases over 7.00%, there are still seven banks offering at least one fixed rate starting with a 5 for owner-occupiers, with the lowest on the Canstar database a now competitive 5.79%.

Canstar analysis shows a borrower with a $600,000 mortgage and 25 years remaining could save an estimated $776 in interest over the next 12 months by opting for the lowest 1-year fixed rate rather than the lowest variable rate, based on CBA’s forecast of a rate hike this month followed by two cash rate cuts from August 2027.

This assumes banks pass on variable rate changes to their customers a month after a cash rate hike. It does not factor in any extra repayments or fees.

Borrowers shouldn’t assume the fixed rate market is devoid of competition

Canstar’s Data Insights Director, Sally Tindall, says, “Australia’s biggest bank has delivered a hefty blow to its fixed rates, jacking up its 2-year loan by 0.48 percentage points – nearly twice the size of a standard cash rate hike.”

“A 0.48 percentage point increase isn’t a tweak, it’s a clear signal Australia’s biggest bank is bracing for higher borrowing costs ahead.

“While the major banks have now pushed their lowest fixed rates well into the sixes, borrowers shouldn’t assume the fixed rate market is completely devoid of competition.

“There are still seven lenders on the Canstar database offering fixed rates starting with a 5 to owner-occupiers, although many of these could well disappear if the RBA hikes the cash rate on Tuesday.

“Anyone considering a fixed rate would do well to look beyond the majors and take their time weighing up their options. Yes, the window on fixed rates starting with a 5 could be closing but when it comes to big financial decisions, it’s important to do your due diligence.

“While in theory, based on current cash rate forecasts, fixing for one year could potentially see you pay less interest. However, the cash rate isn’t set in stone and a lot of borrowers are likely to ride it out. If that’s you, make sure you’re on a competitive rate.”
