Those interest payments are among costs measured in the household living-costs price index, whereas the CPI does not include mortgage rate increases.
“Overall, what it’s showing is that housing costs are still a pretty important squeeze on households’ purchasing power,” Westpac senior economist Satish Ranchhod told the Herald.
Ranchhod said some of that pressure was manifesting in spending data for retail and other parts of the economy, including food and groceries.
“They’re shifting away from the luxury or nice-to-have items, in favour of value-for-money necessities.”
Ranchhod said about 90 per cent of mortgages were fixed and about 60 per cent of them will be refixed this year.
It was most likely they would increase, but at least at a less hectic pace than before, largely because no hike in the Official Cash Rate (OCR) was expected this year.
Ranchhod said Westpac economists right now expected no OCR cuts until early 2025.
Despite the big annual increase, the pace of household inflation did slow in the March quarter.
In the September 2023 quarter, the average household’s living costs went up 2.5 per cent compared to the June quarter.
But in December 2023, that slowed to 1.2 per cent and in this year’s March quarter it slowed again to 1.0 per cent, quarter-on-quarter.
