CME is raising performance bond requirements for COMEX silver futures, lifting both initial and maintenance collateral levels.
In the CME Clearing advisory, the exchange framed the update as part of its normal review of market volatility to ensure adequate collateral coverage, with Clearing House Risk Management staff approving the revised requirements.
For COMEX 5000 Silver Futures under SPAN minimum performance bond requirements, outright rates show increases across month 1 through 4.

Non-HRP SI margins move from a current initial of $20,000 and current maintenance of $20,000 to a new initial of $22,000 and new maintenance of $22,000.
HRP SI margins move from a current initial of $22,000 and current maintenance of $20,000 to a new initial of $24,200 and new maintenance of $22,000.
The margin move lands after a separate, widely discussed episode earlier in December involving a reported nearly ten-hour CME disruption in silver, alongside claims that standing COMEX silver futures buy orders were canceled rather than merely paused.
