Fannie Mae and Freddie Mac should focus on things like cash flow projections, diversified funding and identifying potentially adverse events to manage their liquidity risk, according to a new advisory bulletin issued late this month by the Federal Housing Finance Agency. The regulator said it expects the GSEs to use liquidity metrics that coincide with their funds management strategies and provide a comprehensive view of their liquidity risk to make sure enough funds are available, at reasonable cost, to meet potential demands. “Strong liquidity risk management enables an enterprise to be financially sound to perform its public mission and to limit and control shortfalls in cash,” said the FHFA.
