CME“本轮第六次加保证金”，白银重挫一周跌超40%，再现“历史大顶”模式

Core Viewpoint - The Chicago Mercantile Exchange (CME) has increased margin requirements for both gold and silver futures, indicating a strong regulatory intervention in the silver market as prices have sharply declined, with silver losing the $67 mark and experiencing significant volatility [1][4][6]. Group 1: Margin Increases - CME raised the initial margin for COMEX 100 gold futures from 8% to 9% and for COMEX 5000 silver futures from 15% to 18% [1]. - In the past week, silver has dropped over 40% from its historical high reached on January 29, with a notable 19% drop on Thursday, erasing all gains for the year [4][6]. - CME has increased margin requirements five times in a short span, a rare occurrence that reflects the heightened volatility in the silver market [7]. Group 2: Historical Context and Market Behavior - Historical patterns show that significant drops in silver prices are often preceded by increased margin requirements, indicating a regulatory clampdown on excessive leverage [9]. - The 1980 silver crash is cited as a key example where a sudden regulatory change led to a dramatic price drop, with silver prices falling 67% over four months after reaching a peak [9]. - The current market conditions exhibit extreme volatility, with a volatility rate reaching 1800%, far exceeding the historical average of 200% [12].
