1546 ET - The Federal Reserve's FOMC and its chairman Kevin Warsh just passed their biggest credibility test of the year, Convera's Kevin Ford says in a research note. By uniting to unanimously hike rates and stack the dots for further tightening, the Fed has proved it isn't backing down from sticky inflation, Ford says. Had Warsh moved away from his recent hawkish guidance, it would have deepened questions over the Fed's credibility and independence, given that Trump and his senior administration officials have been pushing for lower rates, Ford says.
