On June 12, the Federal Housing Finance Agency (FHFA) announced a proposed rulemaking, which implements a regulatory capital framework for Freddie Mac and Fannie Mae (the Enterprises) including (i) a new framework for risk-based capital requirements; and (ii) two alternative approaches to setting minimum leverage capital requirements. Regulatory capital requirements for the Enterprises have been suspended since the Enterprises were placed in conservatorship in September 2008, and these new requirements would continue to be suspended while the Enterprises remain under conservatorship. FHFA stated that the purpose of the rulemaking effort is to develop a risk measurement framework to better evaluate each Enterprise’s business decisions while in conservatorship. As a result, the proposed risk-based capital requirements would “provide a granular assessment of credit risk specific to different mortgage loan categories, as well as market risk, operational risk, and going-concern buffer components.” The two options for minimal leverage capital requirements include (i) requiring the Enterprises to hold capital equal to 2.5 percent of total assets and off-balance sheet guarantees related to securitization activities; and (ii) requiring the Enterprises to hold capital equal to 1.5 percent of trust assets and 4 percent of non-trust assets. Comments on the proposed rulemaking must be submitted within 60 days of publication in the Federal Register.
