When testifying to the Senate Banking Committee back in 1987, the newly-appointed Fed Chairman, Alan Greenspan, provided some insight into his views on communication: “Since becoming a central banker”, he said, “I have learned to mumble with great incoherence. If I seem unduly clear to you, you must have misunderstood what I said.”

His successors have generally tried to be more open with regard to both their opinions and their intentions. However, there are times, when the Fed will want to communicate to financial markets without piquing the interest of either the general public or the administration.
