The Federal Housing Finance Agency’s oversight of the 12 Federal Home Loan Banks’ growing amount of advances to insurance companies should be improved to include tighter coordination with state regulatory authorities, according to the agency’s official watchdog. The FHFA Office of Inspector General’s recent audit noted FHLBank advances to insurance company members have dramatically increased even as overall advances have declined in recent years. From 2005 through 2012, the volume of FHLBank advances to insurance companies increased “over fourfold” from $11.5 billion to $52.4 billion.
