Despite indications of heightened risk that the Federal Housing Finance Agency initially missed, the Federal Home Loan Banks substantially increased their unsecured lending to foreign financial institutions in 2010 and 2011, particularly in Europe, according to a report issued this week by the FHFA’s official watchdog. The FHFA’s Office of Inspector General noted that unsecured lending by the FHLBanks swelled from $66 billion at the end of 2008 to more than $120 billion by early 2011, but declined sharply by year-end 2011, as the European sovereign debt crisis continued to worsen.
