Back in April 2011, Jim Bianco penned a commentary, “Why The Federal Reserve May Have A Hard Time Raising Rates.” He argued that the increase in the FDIC insurance assessment rate for large banks adds to bank funding costs, and thus offsets the impact of Fed ease. Bianco and others infer a roughly 15bp tax or “wedge” on money market assets is created by the FDIC assessment rule.  By way of reference, the Fed’s target band for fed funds is 0 to 25bp but has been at low end of this range for months.
