Spot gold closed above $1,800 an ounce Wednesday in its sixth session of gains -- the longest winning streak since May -- after minutes from the Federal Reserve’s June meeting showed policy makers continued to see uncertainty around labor shortages and supply bottlenecks. The precious metal’s recent streak has seen it breach its 100-day moving average, putting a potential test of the 200-day line into play. “Gold looks like a discounted bull market ripe to resume, and may find a catalyst from falling U.S. Treasury bond yields,” according to Bloomberg analyst.
