The U.S. Federal Reserve should delay a rate hike until the first half of 2016 until there are signs of a pickup in wages and inflation, the International Monetary Fund said in its annual assessment of the economy on Thursday. The fund’s report comes amid signs that some rate setters at the U.S. central bank are also pushing for rate hikes to be delayed until there are clearer signs of a sustained recovery. “Based on the mission’s macroeconomic forecast, and barring upside surprises to growth and inflation, this would put lift-off into the first half of 2016,” the fund said.
