While you are risk-weights are a whole lot more traditional, there’s a lower life expectancy load on standardized financial institutions with regards to almost every other supervisory criteria including the handling of internal exposure patterns and you may data reporting.

Based on these features, a houses mortgage are risk-weighted within anywhere between 20 percent and 150 per cent. step three

In IRB strategy, trick determinants off houses chance-loads may be the banks’ estimates off probability of default (PD, the possibility of borrower default), losings considering standard (LGD, loss just like the an amount of the number due at the default) and you will exposure from the standard (EAD, the total amount owing within standard), and you may a threat-lbs function prescribed of the APRA.
