Copper futures are experiencing a four-day losing streak, hitting the 200-day moving average and retreating after Federal Reserve Governor Michelle Bowman noted the U.S. labor market looks "fragile" and inflation sits "not far above 2%." The continued extension of U.S. dollar gains to its highest level since early August is also weighing heavily on global copper prices, as a stronger dollar makes dollar-denominated commodities more expensive for non-U.S. buyers.
