Core Viewpoint of the Report - The expansion of the US fiscal deficit and the Fed's potential interest rate cuts, along with disruptions in production or transportation at multiple overseas copper smelters, are countered by the easing of Sino - US tariffs and the traditional off - season for consumption.
