By increasing the degree of risk attributed to certain assets, the proposed rules would require banks to hold proportionately more capital, potentially eating into returns on equity and profits. Making such lending more expensive will shrink credit available to historically under-served borrowers, something the industry is likely to fight, he said. Chen Xu, an attorney in the financial institutions group at Debevoise & Plimpton, said the new rules viewed high-revenue business lines as higher risk. Morgan Stanley (MS.N) analysts say the largest banks may take up to four years to set aside profits to comply with the new capital rules. Dennis Kelleher, head of the financial reform advocacy group Better Markets, said the banking industry had made similar complaints in the past which he believed had proven unfounded.
