Copper fluctuated as the dollar weakened after Democrats won control of both chambers of Congress in the U.S. midterm elections, an outcome seen as a rebuke to U.S. President Donald Trump. According to Sina Finance, the London benchmark three-month copper contract pared its losses after touching its lowest level since August and was little changed at about $14,000 per metric ton. A weaker dollar supported commodities. Copper has been volatile this year, reaching a record high in September before retreating in recent weeks. Concerns that AI-related spending could weigh on stocks have raised worries about global growth. After the election, traders are focusing on Donald Trump's possible move to impose tariffs on refined copper imports, a risk that has already prompted large volumes of copper to flow into the United States.
