CME Group proposes an amendment to one of its rules to require a minimum summary fine of US $1,000 for inaccurate, incomplete or late filing of data or records. The maximum fine per offense may not be greater than US $5,000 for individuals or US $10,000 for firms. Among the reports that will be subject to summary sanctions include those dealing with large traders, open interest and long positions eligible for delivery; block trades; user IDs (Tag 50); automated/manual indicator on Globex trades (Tag 1028); and customer type indicator codes. CME Group may still issue warning letters for first offenses, and refer egregious matters for disciplinary proceedings. The amendment is scheduled to be effective April 7. In a recent CME Group audit trail rule review, the Commodity Futures Trading Commission recommended that no summary fine should be less than US $1,000.
