Standardised strategy
Under the standardised strategy, resource criteria to possess casing financing derive from a familiar set from chance-weights given by APRA. Standardised risk-weights are often calibrated at a traditional top because they’re faster precise, apply to a wide range of banking institutions, and you may try to make sure that standardized financial institutions are properly capitalised into an overall basis. When you’re risk-loads are generally even more conventional, there is certainly a lesser load towards the standardized finance companies regarding almost every other supervisory criteria for instance the handling of interior risk patterns and you may investigation revealing.
IRB approach
Within the IRB means, banking companies are permitted to utilize their inner activities due to the fact inputs so you’re able to determine the chance-weights to have construction financing.
