Standardized method
According to the standardised method, capital requirements to possess houses credit derive from a common put regarding chance-loads prescribed by APRA. Standardised risk-weights are generally calibrated within a conservative level because they’re shorter direct, apply at numerous banking companies, and endeavor to make sure standardised banking companies is actually effectively capitalised to the a total foundation. If you are risk-loads are usually even more old-fashioned, there’s a diminished burden into standardised banking companies in terms of other supervisory requirements including the handling of internal exposure models and you can analysis revealing.
IRB method
Within the IRB strategy, banks are allowed to utilize their inner habits given that inputs so you can influence the danger-weights to possess houses credit.
