RBNZ steps closer to macroprudential | MacroBusiness

Houses & Holes at Macrobusiness reports on macroprudential steps being considered by the RBNZ. Macroprudential regulation are measures aimed to mitigate the risk of the financial system as a whole, or systemic risk, as opposed to the risk to individual participants.

The [Reserve Bank of New Zealand] says it wants to increase the amount of capital the country’s big four banks must set aside to cover potential losses from high loan to valuation ratio (LVR) home loans. Such a move would, in theory at least, make such lending more expensive for the banks.

Philip Maymin, Why Financial Regulation is Doomed to Fail | Library of Economics and Liberty

Philip Maymin highlights a problem with volatility:

…..securities with historically low volatility tended to have almost twice as much subsequent risk, while those with historically high volatility tended to have almost half as much subsequent risk. For both the riskiest and least risky securities, therefore, historical risk is a statistical illusion.

He further points out that regulation encourages banks to act in concert, increasing systemic risk, while deposit insurance reduces the level of self-imposed discipline among banks.
