Fannie Mae and Freddie Mac mortgage-backed securities remained the preferred investment choice of the 12 Federal Home Loan Banks during the second quarter of 2012, with a modest increase from the previous quarter, according to a new analysis and ranking by Inside The GSEs based on data from the Federal Housing Finance Agency. Meanwhile, Ginnie Mae securities posted an ever-so-slight decline within the FHLBank system during the period ending June 30, 2012.
