Group 1: Market Reaction - On Monday, the spot silver price experienced extreme volatility, initially rising by 6% to nearly $84 per ounce before dropping 4% to $76.15 per ounce, with a low of around $75 during the day [2]. - A rumor circulated on social media regarding a "systemically important bank" facing a margin call in the silver futures market, which drew widespread attention [2][4]. Group 2: Bank's Margin Call - The bank in question reportedly failed to pay an additional $2.3 billion in margin by the required deadline, leading to forced liquidation by the futures exchange [4][7]. - The bank was described as one of the largest participants in the precious metals derivatives market, holding "hundreds of millions of ounces" in short positions [5][6].
