Mortgage collapse foretells much lower house prices

The latest Australian mortgage finance data from the Australian Bureau of Statistics (ABS) recorded heavy falls in new owner-occupier and investor mortgages, which according to Westpac is indicative of a “deepening and broadening housing market correction”:

Australian mortgage commitments

New mortgage demand has collapsed.

Regular readers will know that the value of new mortgage commitments (excluding refinancings) is a strong leading indicator for house prices, as illustrated clearly in the next chart:

New mortgage growth is strongly correlated with house price growth, with mortgages typically leading house prices by between three and six months.

Accordingly, the latest crash in mortgage commitments portends ongoing house price falls at the national level.

The same forces are at play across Australia’s major capital cities.

As noted by Westpac this week, “there is little let-up in sight with other updates showing the housing market correction remains firmly entrenched and the RBA expected to continue ratcheting rates higher in early 2023”.

With the RBA almost certain to lift mortgage rates higher, buyer demand will inevitably shrink, dragging house prices further into the red.
