Gold futures ended lower Tuesday, following moves in the dollar that have weighed on the precious metal in recent weeks amid concerns about trade wars between economic superpowers and tightening monetary policy in the U.S. August gold lost $4.20, or 0.3%, to settle at $1,255.40 an ounce after tacking on about the same percentage amount on Monday. The most popular fund tracking gold, the SPDR Gold Shares was 0.3% lower. September silver traded 5.2 cents, or 0.3%, lower at $16.087 an ounce. The iShares Silver Trust shed 0.5%. A strengthening dollar proved the most significant headwind for precious metals on Tuesday with one measure of the buck, the ICE U.S. Dollar Index which reflects the greenback’s performance against a half-dozen currencies, rising by nearly 0.1% to 94.158. Gold on Monday accumulated modest gains even as the buck rose, but Tuesday’s moves put the dollar gauge on pace to rise 0.1% for the week thus far. Bullion has mostly been in a downtrend that has caused investors and technical analysts to maintain a bearish outlook for the asset that should ordinarily prosper during times of uncertainty, including a spat over trade disputes between the U.S. and its trade partners across the globe. However, the haven asset has shed some of its usual flight-to-safety luster so far. (Source: marketwatch)
