[Fed Mestre: do think the Fed will have to "tighten" monetary policy a little bit] Federal Reserve Mestre said that the policy interest rate for FOMC is at a level that is restrictive to the US economy; it has not yet reached the level to decide whether FOMC's next move is up or down; insufficient tightening and high inflation will be key factors; data released on Friday show that the Fed still has more work to do. Inflation in the core services sector, excluding housing, remains stubbornly high; it is true that we will have to "tighten" monetary policy a little bit.
