When thinking of Australia, one traditionally imagines a country that is nothing but a secondary derivative of China's trade surplus, and an unpegged currency that allows for more trading flexibility than the Yuan. As a result, recurring calls warning of a housing weakness in the country are often ignored as there always appears enough liquidity to mask the issue just long enough. That may all soon be changing. Earlier today, insurance company Genworth Financial pulled the IPO of its Australian unit, sending its shares plunging by over 20% and its default risk soaring. Unfortunately for GNW, and soon for the entire Australian financial sector, instead of merely blaming market conditions, in the IPO, which was supposed to take public up to 40% of the company's Australian mortgage business, and has instead been delayed to 2013, GNW laid out a far more nuanced, and detailed explanation of what is happening. Alas, it also may be the canary in the coalmine that has been so long overdue in yet another regional, bubblelicious housing market.
