CME Group issued a revised Market Regulation Advisory Notice that sets forth infractions subject to summary fines (i.e., fines that are not less than US $1,000 or exceed US $5,000 for individuals, or US $10,000 for firms or facilities for each offense). These infractions include large trader, open interest and long positions eligible for delivery reporting; block trade and exchange of futures for related position reporting; user IDs and automated/manual indicators on CME Globex trades (Tag 50s, Tag 1028s); and customer type indicator codes and registrar reports. Market Regulation noted that it still may issue warning letters for a first offense although no person may receive more than one warning letter for the same offense during a rolling 12-month period.
