As the Federal Reserve’s open markets committee meets for its crucial two-day session in Washington, Janet Yellen faces her first real policy test since assuming the chair in February 2014. Amazingly, she is already almost halfway through her first term. But, so far she has had the relatively easy task of piloting the exit from quantitative easing. The exit plan had already been mapped out by Ben Bernanke, and it was not particularly contentious inside the committee.

The decision on whether to raise interest rates this week is, however, proving more divisive. Among her key lieutenants, vice-chair Stanley Fischer seems somewhat hawkish, while William Dudley has stated the case for the doves. John Williams, her successor at the helm of the San Francisco Fed, and a key ally, also seems inclined to a more dovish view than he championed earlier in the summer.

Mr Williams recently told the Wall Street Journal that he would “honestly, honestly, honestly” want to hear the opinions of his colleagues at this week’s meeting before making up his mind. Does he protest too much, I wonder? Perhaps the decision has already been taken, but the Yellen camp wants to allow the hawks a full and fair hearing before announcing that rates would remain unchanged.
