白银一周跌超40%，再现“历史大顶”模式

Core Viewpoint - The article discusses the recent volatility in the silver market, highlighting the significant increase in margin requirements by the Chicago Mercantile Exchange (CME) and its historical implications for silver prices [2][5]. Group 1: Margin Increases - On February 5, CME announced an increase in initial margin requirements for COMEX 100 gold futures from 8% to 9% and for COMEX 5000 silver futures from 15% to 18% [2]. - The past week saw spot silver prices drop over 40% from a historical high reached on January 29, with a notable 19% decline on Thursday, erasing all gains for the year [4]. Group 2: Historical Context - Historical patterns indicate that significant increases in margin requirements often precede peaks in silver prices, with CME showing strong regulatory intervention in the current silver market [5]. - The article references past silver crashes, notably in 1980 and 2011, where regulatory actions such as margin hikes led to dramatic price declines [13][16]. Group 3: Market Dynamics - The article emphasizes that silver price collapses are not merely due to high prices but are the result of high volatility, leverage, and regulatory actions that force deleveraging [13][19]. - Current market conditions show extreme volatility, with a volatility rate reaching 1800%, significantly above the historical average of 200% [17]. Group 4: Price Discrepancies - The silver-to-oil ratio has reached 1.8, far exceeding the historical range of 0.2 to 0.5, indicating a significant distortion in pricing [18]. - The confirmation of market tops often occurs with sudden regulatory changes, which can lead to a rapid collapse in prices as leveraged positions are unwound [19][20].
