Gold futures rallied, rising back above the psychological $4,000 mark ahead of the Federal Reserve's interest rate decision. Futures climbed up to $4,046.20. Traders widely expected the US central bank to lower interest rates by 25 basis points, a move that tends to boost non-yielding assets like Gold futures, which remains up more than 50% this year. The CME FedWatch Tool showed a 99.9% chance of a 25 basis point interest rate cut at Wednesday's meeting, shifting investor focus to the Fed Chair's commentary for guidance on a potential follow-up move in December. Central bank buying continues to support the precious metal as investors seek safe-haven assets. Industrial metals also saw gains, with Copper futures jumping 1.5%. The rally in Copper and Silver futures was catalyzed by the prospect of easing US-China trade tensions, building on previous mine supply setbacks and concerns about physical tightness outside the US. Copper futures continue to show higher highs and higher lows on the chart.
