Fed's Exit Strategy

Fed's chairman Ben Bernanke published an article in WSJ explaining the central bank's financial exit strategy after it pumped billions into the economy in an attempt to fight the negative effects of the crisis.
The Fed will need "to tighten monetary policy to prevent the emergence of an inflation problem," Bernanke writes. This should be achieved by eliminating large reserve balances of banks. To do that, the Fed could increase its target for federal funds rate, attracting liquidity back into its own hands. Moreover, in case the federal funds rate does not react sufficiently to the rate Fed will pay on deposited reserves, the Reserve or the Treasury could arrange large-scale "reverse repurchase agreements" - that is, issuing their own securities and sterilizing thus gained liquidity.
The timing and pace of such instrument should best foster Fed's objectives of maximum employment and price stability, the chairman concludes.
