The Federal Housing Finance Board is set to formally adopt big changes in the way its staff deal with the Federal Home Loan Banks. The agency has drafted new “standards of conduct” governing how its directors, officers and examiners interact with the 12 FHLBanks. In the past there have been suggestions that the FHLBanks are much too cozy with their regulator and the new standards are clearly aimed at dispelling any appearance of impropriety.
