    higher rates should go and how to explain their thinking to financial markets. Stop too soon and inflation, already close to the top of the Fed s informal comfort zone, could become a problem. Raise rates too far or fail to make the strategy clear, and the consequences for America s unbalanced, debt-laden economy could be calamitous. On March 27th Mr Bernanke will chair his first two-day meeting of the Federal Open Market Committee (FOMC), the central bank s rate-setting body. Financial markets believe that another quarter-point rise is almost inevitable. Less obvious is how the change in the leadership and composition of the FOMC (which consists of the Fed s board of governors and the presidents of re fuel dispenser gional Federal Reserve Banks, not all of whom vote) will influence monetary policy thereafter. Comings and goings Though Mr Bernanke s arrival is the most important, it is not the committee s only change. Roger Ferguson, vice- chairman since 1997, is leaving and will not take part next week. Nor will a non-voting member, Anthony Santomero, departing president of the Federal Reserve Bank of Philadelphia. Two new governors, recently appointed by George Bush, will make their debuts Randy Kroszner, a respected economist from the University of Chicago and former member of Mr Bush s Council of Economic Advisers, and Kevin Warsh, a young White House aide. Those prone to worry have pointed out that the board is short of expertise in monetary policy. Mr Bernanke and Don Kohn, an experienced central banker, are the only members with backgrounds in the field. Mr Kroszner is an able fuel dispenser academic, but his specialities are banking and financial regulation. Much more alarming, Mr Warsh is seen as a shockingly lightweight appointment. This may not matter much. Mr Bernanke has a stronger academic background than any of his predecessors. Several of the regional Fed presidents are able macroeconomists, notably Janet Yellen of the Federal Reserve Bank of San Francisco. Taken as a whole, the fuel dispenser FOMC has the
