The recent downturn in Australian house prices, marked by the 5-city aggregate index hitting 0% growth, signals a prolonged period of negative growth. This phenomenon, dubbed 'Donut Day', is driven by a 'perfect storm' of factors. Firstly, home prices have detached from borrowing capacity, exacerbated by recent rate hikes and expected future increases. Secondly, changes to negative gearing and capital gains taxes are reducing investor demand, a key growth driver. Lastly, rising unemployment due to higher interest rates and global energy shocks further depresses home prices. The auction clearance rate decline and falling sales volumes below the 5-year average indicate softer buyer demand. This correction is likely to be the largest in 40 years, surpassing the 2017-2019 decline, as Sydney and Melbourne's losses spread to other markets. The article concludes by emphasizing the depth and breadth of this housing downturn, urging readers to prepare for a significant economic adjustment.
