Federal Reserve Vice Chairman Richard Clarida on Friday morning said he sees 'signs of slowing growth' and that sluggish expansion in the globe will be factored in the central bank's calculus as it attempts to normalize interest-rate policy. Clarida said during an nterview on CNBC that "we have to factor in to the global economy and there is some evidence of global slowing." Clarida, who was appointed by President Donald Trump, also offered a more dovish take on key features of policy maker's decision making in lifting interest rates, with a fourth rate hike in 2018 expected next month. However, Clarida disagreed with the notion that the Fed is hiking rates too quickly, a criticism leveled repeatedly by President Donald Trump. Clarida appeared to walk back comments that Fed Chairman Jerome Powell did a few weeks ago, when he declared that the central bank is nowhere near a rate of neutral, one that neither slows or boosts the economy. He said that "getting closer toward" the vicinity of that range. Clarida emphasized the strength of the U.S. economy and the labor market particularly. Futures for the Dow Jones Industrial Average briefly deepened losses, while those for the S&P 500 index also added to early gains. The Dow , the S&P 500 and the Nasdaq Composite Index are all expected to open lower on Friday. Bond yields also rolled back after Clarida's comments, with the 10-year Treasury note yield ticking back to 3.08%, while the dollar, as measured by the ICE U.S. Dollar Index , edged back, currently down 0.4% at 96.35.
