Fannie Mae says portfolio, delinquency rates rise

NEW YORK, Sept 30 (Reuters) - Fannie Mae (FNM.P), the largest provider of funding for U.S. home mortgages, on Tuesday said the rate of growth in its investment portfolio slowed in August to a level not seen since the spring.

The rate of delinquencies on loans guaranteed by the company in July shot up the most in at least a year.

Fannie Mae's mortgage investment portfolio increased at a 3 percent annualized rate last month to $759.98 billion, the Washington-based company said in a statement. Its agreements to buy mortgages in months ahead fell to $25 billion in August from $43.3 billion in July. (Reporting by Al Yoon; Editing by Jan Paschal)
