February business volume of nearly $40.2 billion fell $7.9 billion from the previous month, according to Fannie's latest monthly summary. The figure is well below the $50.8 billion a year ago.
Portfolio purchases of $9.4 billion and $30.7 billion in mortgage-backed securities acquired by others comprised February's volume, the Washington, D.C.-based company said.
Fannie's book of business, reported at $2.3 trillion, consisted of $1.4 trillion outstanding MBS and an $0.9 trillion gross mortgage portfolio.
