CME Group(US:CME) Ge Lin Qi Huo·2025-12-29 03:05Group 1 - Report Core View - On December 26, 2025, the London spot silver rose by over 10% and reached $79 per ounce. The CME Group announced a significant margin adjustment, increasing the initial margins for gold, silver, and lithium futures contracts after the close on December 29. The initial margins for COMEX 100 - ounce gold futures (GC) Non - HRP and HRP contracts were raised by 10%, and those for COMEX 5000 - ounce silver futures (SI) Non - HRP and HRP contracts were increased by over 13%. The market believes this reflects the exchange's deep concern about the abnormal fluctuations in the precious metal market [2]. - On December 29, the London spot silver opened above $80 per ounce, reaching a high of $83.971 per ounce and then quickly dropping to near $75 per ounce. In 2011, the CME Group also raised silver futures margins multiple times, causing a sharp short - term decline in silver futures prices. Given the short - term volatility of silver, investors are advised to consider their risk tolerance and control investment risks. Gold has a relatively smaller fluctuation range due to its slower previous price increase [2].
