FICC - MBS Alert! Moving MBSD Deterministic Risk Component to Cash Only Settlement; Intraday Mark-to-Market Charge and Intraday VaR Charge. Due to recent market volatility, FICC will be raising the backtesting coverage threshold for intraday margin calls

Source

During normal market conditions, the Intraday Mark-to-Market Charge applies to Clearing Members that experience an intraday increase in Mark-to-Market exposure that exceeds (i) a dollar threshold of $1,000,000, (ii) a percentage threshold of 30% as compared to the daily VaR Charge, and that have 12-month backtesting coverage below a target of 99%. Due to recent market volatility, FICC will be raising the backtesting coverage threshold for intraday margin calls to 100% in order to prevent backtesting deficiencies. FICC will also be applying a trading day threshold for intraday margin collection. Clearing Members who have less than 100 trading days in a rolling 12-month period, and who breach the threshold for (i) and (ii), will be assessed an Intraday Mark-to-Market Charge, regardless of their backtesting coverage.
