The U.S. Federal Reserve Bank should complete its planned $600 billion in bond purchases, but probably does not need to do buy additional bonds to support the economy, a top Fed official said on Monday.

“The question is, would we need to add more, or would the economy be at a point where can grow on its own with that accommodation?” Chicago Fed President Charles Evans said.

“Even when we stop making purchases there will still be a lot of accommodation in place,” he said.

If core inflation rises closer to 1.5 percent, “maybe that will be the time when I’ll be more concerned about it,” he said.
