Copper Prices Trading at High Levels: Transformer Industry Faces Severe Cost Pressure
2025-12-27
On December 27, 2025, the front-month Shanghai copper contract surged 3.33%, climbing 3,270 yuan per ton to close at 101,380 yuan per ton after hitting an intraday high of 102,660 yuan per ton. Since copper accounts for over 60% of transformer production costs, the price hike has sharply squeezed the profit margins of transformer manufacturers, particularly for small and medium-sized orders. Market data reflected strong trading activity, with capital inflows moving in tandem with price gains. Analysts attributed the rally to supply disruptions at South American copper mines and robust demand from power grid upgrades and new energy storage, forecasting that copper prices will stay high in the short term.
