While US mortgage holders tend to borrow over 30-year terms, insulating them from tightening cycles, a majority of Australian borrowers are on variable rate home loans that adjust upwards each time the central bank hikes. 

Australia’s housing market is already in a downturn and higher borrowing costs are likely to drive more declines this year. 

There’s a further risk from re-pricing of loans that were fixed for 2-3 years at record-low rates during the pandemic. RBA data suggest 23% of all outstanding mortgage debt will be re-priced this year and in some cases borrowing costs will more than double to close to 6%. 

While the RBA is relatively sanguine about housing, Eliza Owen, head of research at property consultancy CoreLogic Inc., sees risks on the horizon.

“Australians with fixed-rate loans are about to see a painful adjustment. This is partly the intention of rising rates,” Owen said. “The true test of the market will be over the next 10 months.”

Australia, “the lucky country” avoided recessions between the early 1990s and the pandemic because many of the troubles assailing the rest of the world did not impact the domestic market. Moreover the boom of Chinese demand, for just about everything Australia exports, was a major boost to the economy over the last twenty years and insulated Australia from the credit crisis.
