If anything penetrates the thick skulls at the Lunatic RBA it might be the constant humiliation it receives at the hands of the RBNZ, a vastly superior central bank on every measure.
The RBNZ handles both monetary and prudential policy with 20% the staff of RBA and APRA. This enabled it to lead on macroprudential policies for years while ours gawked at their housing bubble.
The RBNZ led on financial stability, forcing Australian-ponzi banks to hold much higher capital than Australian parents to ensure taxpayers are not exposed to poor lending practices.
