Banks May Face Stiffer RBC Mortgage Rules

Banks and thrifts holding fairly conservative one- to four-family mortgages would see their risk-based capital requirement jump from a 35% to a 100% risk weighting if the borrower missed three monthly payments under an RBC proposal federal banking regulators call the Basel II "standardized approach." Riskier residential mortgages with higher loan-to-value ratios or stand-alone home equity loans that become 90 days or more past due could end up with a 150% risk weighting, according to Federal Deposit Insurance Corp. officials. The FDIC board has approved the issuance of the proposed standardized approach for a 90-day comment period. The Federal Reserve Board was slated to meet June 26 to consider the notice of proposed rulemaking. The regulators have decided to scrap a Basel Ia RBC rule and move toward the standardized approach that could be adopted by most FDIC-insured institutions. The 11 largest U.S. banking organizations are required to implement the more advanced Basel II approach. The standardized approach incorporates the more risk-sensitive risk weightings for mortgage loans in Basel Ia and adds a surcharge for operational risk based on 15% of net interest income. It also imposes a capital surcharge on nontraditional mortgages to address risks associated with negative amortization. Restructured single-family loans would generally fall into a 100% risk weighting.
