"I believe that labor market conditions warrant scaling back the pace of purchases as soon as our next meeting," said Plosser in prepared remarks. "Moreover, unless we see a significant reversal in current trends that jeopardizes my forecast of near 7% unemployment rate by the end of this year, then I anticipate that we could end the program before year-end."
