In addition to providing loans to other banks in the interbank market, banks provide loans to securities firms. The securities firms use these loans to fund the purchase of securities. Exposures to these securities firms shall be treated as claims on banks if these firms are subject to prudential standards and a level of supervision that is equivalent to those applicable to banks. Such supervision must include at least both capital and liquidity requirements. Exposures to all other securities firms that are not treated as claims on banks will be treated as exposures to corporates.
