How prudential standards influence property lending
Capital adequacy
Banks must hold capital against the loans they make. The capital framework assigns higher risk weights to loans considered riskier, which means the bank must hold more of its own capital for each dollar lent. Land subdivision, development and some commercial property loans attract higher risk weights than standard home loans. Holding more capital makes these loans more expensive for the bank, which narrows its appetite.
Credit risk management
APRA's credit risk management standard expects banks to have sound policies for assessing, approving and monitoring loans, including concentration limits and valuation practices. For development lending, this usually translates into pre-sale requirements, cost-to-complete tests, quantity surveyor reports and strict loan-to-value limits. Our lesson on LVR, ICR, DSCR and other ratios explains these measures.
Large exposures and concentration
Banks must limit their exposure to single borrowers and to concentrations in particular sectors. A bank that already has a lot of development lending in one city may decline a new project there, even if the project itself is sound.
Serviceability for residential lending
For home lending, APRA has set expectations about the interest rate buffer banks use when testing whether a borrower can afford repayments. These settings affect how much individuals can borrow and are set out in APRA's guidance on residential mortgage lending.
