The regulatory framework of the chilean financial system includes a number of regulations that seek to maintain the financial stability of banks. On one hand, the Central Bank of Chile in its role as regulator and, on the other hand, the Superintendency of Banks in its role as supervisor have set a variety of prudential regulations such as margin lending requirements, property-related concentration margin lending requirements, property-related concentration margins, limits on market risk exposure, and capital adequacy requirements. (The capital adequacy requirements are based on Basle principles and were established after the enactment of a new banking law sought to replace leverage ratios). This set of regulations is reinforced through periodic on-site supervision of financial institutions, a task for which the Superintendency of banks is responsible.
