Spot gold rose 2% to break through the $4,000 milestone, while silver surged 4% as the Democrats winning control of Congress dragged down the US dollar. Early Tuesday morning EST, spot gold gained 2% to $4,005.40 per ounce, and spot silver surged 4% to $51.68; over the same period, the DXY fell by about 0.3%, driven by the Democratic Party winning control of Congress in the US midterm elections, which sparked concerns over the fiscal and interest rate outlook.
