金属普跌 期铜持稳，市场等待鲍威尔杰克逊霍尔讲话【8月21日LME收盘】

Core Viewpoint - The London Metal Exchange (LME) copper prices remained stable as the market awaited signals regarding U.S. interest rate policy from the Federal Reserve's annual symposium in Jackson Hole, Wyoming, with a slight increase in copper prices noted [1]. Group 1: Market Performance - On August 21, LME three-month copper rose by $4, or 0.04%, closing at $9,724.50 per ton, after hitting a low of $9,670.50 on August 20, the lowest since August 7 [1][2]. - Other base metals showed mixed performance, with three-month aluminum up by $8.50 (0.33%) to $2,585.00, while three-month zinc, lead, tin, and nickel experienced declines [2]. Group 2: Economic Indicators - Recent data indicated a recovery in U.S. manufacturing, with August business activity accelerating and order growth reaching the strongest level in 18 months, while the Eurozone saw its first manufacturing expansion in over three years [4]. - The likelihood of a rate cut by the Federal Reserve next month has slightly decreased, providing support for the U.S. dollar, which in turn makes dollar-denominated metals more expensive for buyers using other currencies [4]. Group 3: Supply Dynamics - Codelco, a major Chilean copper producer, announced a reduction in its 2025 production forecast by 33,000 tons due to an accident at its El Teniente mine, which is expected to impact overall copper supply [4]. - The International Copper Study Group (ICSG) reported a global copper market surplus of 251,000 tons for the first half of 2025, down from a surplus of 395,000 tons in the same period last year, with refined copper production increasing to 14.21 million tons from 13.72 million tons year-on-year [5]. Group 4: Future Price Outlook - Goldman Sachs anticipates that increased defense spending in the European Union will significantly boost industrial metal demand, projecting upward price risks for copper in 2026 and 2027, with expected prices of $10,000 and $10,750 per ton, respectively [5].
