重要商品指数再平衡今日开启，两大投行预言“白银两周内调整”，高盛“关键还是伦敦”

Core Viewpoint - The upcoming annual rebalancing of the Bloomberg Commodity Index (BCOM) will significantly reduce the weight of gold from 20.4% to 14.9% and silver from 9.6% to 3.94%, leading to substantial selling pressure on silver [1][2]. Group 1: Rebalancing Impact - Deutsche Bank and TD Securities estimate that $7.7 billion worth of silver will flood the market in the next two weeks, equating to 13% of the total open interest in the COMEX silver market, which may trigger a significant price correction [2][10]. - The rebalancing process is expected to unfold over several days, not just one, indicating a prolonged period of selling pressure on precious metals, particularly silver [5]. Group 2: Market Reactions - Analysts from Deutsche Bank suggest that the rebalancing will negatively impact precious metals while benefiting crude oil [3][5]. - TD Securities highlights that the trading volume of the largest silver ETF has reached extreme levels, typically seen only at market peaks, indicating speculative fervor among retail investors [3][10]. Group 3: Supply and Demand Dynamics - Goldman Sachs emphasizes that liquidity in the London market is crucial for determining silver price trends, with tight inventory conditions likely to lead to extreme price volatility [4][12]. - The current tightness in the London market is exacerbated by speculative activities surrounding U.S. trade policies, which have led to a significant outflow of silver from London inventories [12][13]. Group 4: Price Sensitivity - Deutsche Bank estimates that a sale of 2.4 million ounces of gold could lead to a price drop of 2.5%-3.0%, depending on the sensitivity model used [7]. - In tight market conditions, the sensitivity of silver prices to net demand has increased significantly, with a typical weekly demand of 1,000 tons pushing prices up by about 2%, now heightened to 7% [13].
