Investment banks (IBs) want Bank Negara Malaysia to withdraw the property lending guideline, which was introduced in 1997. It stipulates that a bank’s credit facilities should not exceed 20% of its total outstanding loan base. Compliance with this requirement is calculated on a quarterly basis. For IBs, the guideline mainly affects their underwriting business. They think the guideline is outdated, especially since there are already other macroprudential measures introduced by Bank Negara in recent years. The Malaysian Investment Banking Association (MIBA) had highlighted the issues affecting the industry to Bank Negara. It is understood that the central bank is currently reviewing the guideline.
