Fed officials were quite chatty this week. There was plenty of talk on the yield curve, including who flattened it and whether we should be worried about its evolving shape. The magic number of interest-rate increases this year is still up for debate, with Dallas Fed President Robert Kaplan and Atlanta’s Raphael Bostic sticking to three hikes this year as a base case, and the San Francisco Fed’s John Williams seeing as many as four. Cleveland Fed chief Loretta Mester told Bloomberg that slow and steady inflation supports the Fed’s gradual rate-hike path. Richard Clarida, President Donald Trump’s nominee for the No. 2 job at the Federal Reserve, is sounding a lot like Chairman Jerome Powell.
