Gold sank in Thursday trading after a trio of reports suggested a stronger U.S. economy, potentially signaling that the Federal Reserve will begin tapering its monthly bond-buying sooner rather than later.

The Institute for Supply Management reported that its service sector index climbed to a reading of 58.6 in August, up from 56 in July. The Labor Department said that first time claims for unemployment benefits last week came in below economists’ forecasts. Finally, the government revised upward its estimate of second-quarter worker productivity growth to an annual rate of 2.3%.

The Fed has said that it will ease its stimulus efforts if the economy continues to improve. The U.S. dollar gained on the news.
