      Rule 526. BLOCK TRADES (in Part)

      The Exchange shall designate the products in which block trades shall be permitted and determine the minimum quantity thresholds for such transactions. The following shall govern block trades:

      F. Unless otherwise agreed to by the principal counterparties to the block trade, the seller, or, in the case of a brokered transaction, the broker handling the block trade, must ensure that each block trade is reported to the Exchange within the time period and in the manner specified by the Exchange. The report must include the contract, contract month, price, quantity of the transaction, the respective clearing members, the time of execution, and, for options, strike price, put or call and expiration month. The Exchange shall promptly publish such information separately from the reports of transactions in the regular market.

      RA2204-5 (in part):

      Block Trade Submission

      Please note that the execution time of a block trade is the time that the trade is consummated, which is the time that the parties agree to the trade in principle. Market Participants must accurately report the execution time of the block trade. The reporting of inaccurate execution times may result in disciplinary action.

      RULE 432.W. GENERAL OFFENSES (in part)

      It shall be an offense:

      W. for any party to fail to diligently supervise its employees and agents in the conduct of their business relating to the Exchange.


      Pursuant to an offer of settlement in which StoneX neither admitted nor denied the rule violations or factual findings upon which the penalty is based, on November 15, 2023, a Panel of the Chicago Mercantile Exchange (“CME”) Business Conduct Committee (“Panel”) found that from September 6, 2022, through September 28, 2022, StoneX submitted block trades to the Exchange with inaccurate execution times and failed to report block trades to the Exchange within the required time period following execution in Three-Month SOFR futures and Eurodollar options on futures markets. Additionally, the Panel found that StoneX failed to diligently supervise, monitor, and sufficiently train its employees as to relevant Exchange rules and Market Regulation Advisory Notices in a manner sufficient to ensure compliance with the same.

      The Panel thereby concluded that StoneX violated CME Rules 526, 526.F., and 432.W.


      In accordance with the settlement offer, the Panel ordered StoneX to pay a $70,000 fine.
