Mortgage holders across Australia are likely to be hit with an interest rate hike next week, according to a survey of experts. Mortgage holders are likely to be hit with an interest rate hike next week, experts forecast. This is a marked turnaround from last December when only 9 per cent of experts in a Finder survey forecast a February rates lift. On a $1 million mortgage, the same hike would cost a homeowner nearly $1893 a year more in interest – a rise of $158. A rates rise next week would be the first in Australia since November 2023, and would follow the RBA's easing cycle that brought relief for mortgage holders.
