In something of a surprise move, ASB has broken ranks and raised home loan rates for fixed terms of less than two years.
These increases set ASB's rate card higher than its main rivals.
ASB has raised its six month fixed rate to 7.09%, an increase of 20 basis points (bps).
ASB has raised its one year fixed rate to 7.04%, an increase of 26 bps.
And it has raised its 18 month fixed rate to 6.75%, an increase of 6 bps.
The bank hasn't changed any other rate at this time.
That means the ASB one year rate is now 44 bps higher than key rivals ANZ, BNZ and Kiwibank, and 6 bps higher than Westpac.
This is perhaps even more of a surprise given that ASB had the highest net interest margin (NIM) of all the main banks. According to the March data released two days ago by the Reserve Bank, that ASB NIM was 2.5% - all the others were lower, and the ASB higher margin has been like that since September 2022.
Competitively, it is the two Chinese banks, ICBC and Bank of China, who offer the lowest rates now for terms of one to two years.
But there are still fixed rates below 6% on offer. BNZ, ANZ and Heartland Bank offer 5.99% fixed for three years. And Westpac also offers 5.99% for four and five year fixed terms.
On Thursday, wholesale swap rates were little-changed across the board. But from the start of May, wholesale swap rates have risen about 20 bps across most terms, somewhat in line with the 25 bps May 24 Official Cash Rate hike.
But with loan demand, especially mortgage demand unusually low, sourcing wholesale funding is unlikely to be a priority. Depositor and saver inflows remain positive, so wholesale loan activity is only likely to be rollovers. However, savers are racing back into term deposits and that will raise bank interest costs noticeably.
ASB itself also raised some [minor] term deposit (TD) offer rates. Its five month TD rate rose 20 bps to 4.50%, its six month rate is up 5 bps to 5.60% and nine month rate is up 10 bps to 5.60%. These rises just match their main rivals.
One useful way to make sense of the changed home loan rates is to use our full-function mortgage calculator which is also below. (Term deposit rates can be assessed using this calculator).
And if you already have a fixed term mortgage that is not up for renewal at this time, our break fee calculator may help you assess your options. But break fees should be minimal in a rising market.
Here is the updated snapshot of the lowest advertised fixed-term mortgage rates on offer from the key retail banks at the moment.
