East Coast house prices fall from peak.
Ultimately, how far house prices fall will depend on how aggressively the Reserve Bank of Australia (RBA) hikes interest rates, given higher mortgage rates lowers borrowing capacity and reduces housing demand.
In the RBA’s monetary policy statement accompanying Tuesday’s rate hike, governor Phil Lowe noted that “inflation in Australia is the highest it has been since the early 1990s and is expected to increase further over the months ahead”. As such, “the Board expects to increase interest rates further over the months ahead”.
Therefore, mortgage rates will continue to rise, which will further lower borrowing capacity and reduce home buyer demand. This will inevitably push house prices lower.
