Abstract: A credit monitoring system is configured to receive data on derivative trades associated with the trading entities, determine credit limit data associated with the trading entities, determine an amount at risk for each of the derivative trades and adjust the credit limit data based on the derivatives trades. The credit limit data and derivative trade data, and warnings about credit exposure approaching credit limits, may be communicated to the future commission merchants, enabling control and/or adjustment of the credit exposure of their respective trading entities. Advantageously, the monitoring system can also be expanded to include multiple swap execution facilities through centralized collection of the trading data from the swap execution facilities and/or from a swap data repository.
