The Conference Board’s US leading economic index edged up in August, suggesting moderate growth will continue for the remainder of 2015. Separately, the Federal Reserve opted to leave interest rates unchanged.

The New York Times reported the decision was a close call and rates could go up this year.

Meanwhile, The Conference Board’s US leading economic index rose 0.1% in August to a reading of 123.7 (2010 = 100), following no change in July and a 0.6% increase in June.

“The US [leading economic index] suggests economic growth will remain moderate into the New Year, with little reason to expect growth to pick up substantially,” said Ataman Ozyildirim, director of business cycles and growth research at The Conference Board. “Average working hours and new orders in manufacturing have been weak, pointing to more slow growth in the industrial sector. However, employment, personal income and manufacturing and trade sales have all been rising, helping to offset the weakness in industrial production in recent months.”
