Various assessments are emerging ahead of the U.S. Federal Reserve′s decision on whether to raise rates for the first time in more than nine years. The International Monetary Fund says the Fed should take a more cautious approach before hiking interest rates. In a report released on Thursday, the IMF said the Federal Open Market Committee should wait until they see firm signs of inflation rising toward its target of two percent, as well as continued strength in the labor market. On the same day, regional Fed presidents James Bullard and Jeffrey Lacker said at an annual monetary conference in Washington that the central bank no longer needed to keep rates near zero as inflation was near its goal. Fed Chair Janet Yellen, who also gave a speech at the conference, did not specify her stance on the rate path.
