Between May 2022 and December 2023, the cash rate jumped from 0.1 per cent to 4.35 per cent, or 425 basis points. The interest rate paid by mortgage borrowers increased by around 320 basis points. In other words, borrowers did not feel the full impact of higher interest rates.
Were the banks being nice to customers? Not really.
According to a Reserve Bank discussion paper, there were two key reasons why the full impact of the higher cash rate did not hit people with a home loan. The first is that so many people had locked into low rate, fixed term loans. Variable rates might have risen, but fixed rates remained fixed.
The second reason was the effects of heightened mortgage lending competition. The more lenders competing for your mortgage, the better outcome for customers.
The discussion paper said that most of the increase in lending costs had been passed through by the end of December 2024.
The moral of the story is that while official interest rates are rising, and borrowers can’t do much about that, they can work harder looking for better deals. That is the best way to minimise the impact of higher interest rates.
