In the last few days, we have witnessed an almost unprecedented chorus of warnings about inflation prospects by senior Fed officials. Dallas Fed President Richard Fisher said the Fed must be prepared to tighten monetary policy by raising short-term interest rates with “alacrity.” President Charles Plosser of Philadelphia had spoken of the need to raise interest rates before unemployment returns to normal in order “to prevent the Second Great Inflation.” The comments of the two Reserve Bank presidents reinforce those made by Fed Governor Kevin Warsh.

Financial markets are confused because the Fed’s policy-making committee (the Federal Open Market Committee) had just indicated its intention to keep interest rates low for an extended period. The inflation warnings represent an internal debate that has gone public. Formal dissents from the FOMCs policy directive have reportedly been discouraged. So Fed officials are in effect offering up virtual dissents in public speeches. Confidence in Chairman Bernanke’s policy is waning.

Most economic forecasters profess to see little inflation risk. They need to reconsider their forecasts in light of the inflation warnings from within the central bank.
