Investors' attention looks set to switch, briefly, to monetary policy for the rest of the week, from its usual recent fixation with trade and politics. The Federal Reserve is up first, later today, followed on Thursday by the Bank of England, Sweden's Riksbank and Swiss National Bank. All but the SNB are expected to leave rates on hold, as the Bank of Japan did earlier in the day. The focus will fall on how far they might signal their policy intentions or their sensitivity to the recent market gyrations around U.S. tariffs and the prospect of slowing growth.
