CME Group exchanges proposed to amend a Market Regulation Advisory Notice to make clear that the consent required from a customer by a broker or counterparty to disclose the identity of the customer in a proposed block trade must be “express” consent only. This may be evidenced by a letter, email, instant message, or recorded phone line and such evidence must be provided to Market Regulation upon request. Consent is not required trade-by-trade but must be obtained no less than annually. ICE Futures U.S. also proposed similar amendments to its block trade rule and associated guidance that were effective on January 27, 2020.
