Fed Chairman Jerome “Jay” Powell will speak on Friday in Switzerland.

Wall Street always hopes that he will tip off future interest rate policy. But it will be more interesting to see whether Powell says anything about Trump’s desire to have the Fed help him win re-election or weigh in on comments by former New York Federal Reserve President Bill Dudley that the Fed should work against the president.

I don’t expect him to bring up either Trump or Dudley by name. But we can hope Powell will have had enough and address the substance of these issues.
