Fannie Mae's secondary market purchases improved on a monthly basis, but not for the quarter.
Business volume of $47.3 billion in March was about $2.3 billion better than the previous month's level and $4.9 billion higher than the comparable period a year ago, according to Fannie's latest monthly summary report.
However, total first quarter business volume of $143.5 billion was off $17.7 billion and $37.6 billion from the prior three-month period and the year-ago first quarter, respectively, the Washington, D.C.-based company said.
Mortgage-backed securities acquired by others of $33.2 billion and portfolio purchases of $14.2 reportedly made up March's business volume.
The secondary lender said its $2.4 trillion book of business contained over $1.6 trillion in outstanding MBS and a $0.7 trillion gross mortgage portfolio.
Delinquency, which Fannie reports on a one-month lag, for loans past due 90 or more days fell three BPS from the previous month to 0.77% in February.
Unchanged since November, the effective duration gap, or measure of the exposure to interest rate risk, was zero months, according to the report.
