Section 37.9 - Methods of execution for required and permitted transactions(a)Execution methods for required transactions.(1)Required transaction means any transaction involving a swap that is subject to the trade execution requirement in section 2(h)(8) of the Act.(2)Execution methods.(i) Each Required Transaction that is not a block trade as defined in § 43.2 of this chapter shall be executed on a swap execution facility in accordance with one of the following methods of execution except as provided in paragraph (d) or (e) of this section:(A) An Order Book as defined in § 37.3(a)(3) ; or(B) A Request for Quote System, as defined in paragraph (a)(3) of this section, that operates in conjunction with an Order Book as defined in § 37.3(a)(3) .(ii) In providing either one of the execution methods set forth in paragraph (a)(2)(i)(A) or (B) of this section, a swap execution facility may for purposes of execution and communication use any means of interstate commerce, including, but not limited to, the mail, internet, email, and telephone, provided that the chosen execution method satisfies the requirements provided in § 37.3(a)(3) for Order Books or in paragraph (a)(3) of this section for Request for Quote Systems.(3)Request for quote system means a trading system or platform in which a market participant transmits a request for a quote to buy or sell a specific instrument to no less than three market participants in the trading system or platform, to which all such market participants may respond. The three market participants shall not be affiliates of or controlled by the requester and shall not be affiliates of or controlled by each other. A swap execution facility that offers a request for quote system in connection with Required Transactions shall provide the following functionality: (i) At the same time that the requester receives the first responsive bid or offer, the swap execution facility shall communicate to the requester any firm bid or offer pertaining to the same instrument resting on any of the swap execution facility's Order Books, as defined in § 37.3(a)(3) ;(ii) The swap execution facility shall provide the requester with the ability to execute against such firm resting bids or offers along with any responsive orders; and(iii) The swap execution facility shall ensure that its trading protocols provide each of its market participants with equal priority in receiving requests for quotes and in transmitting and displaying for execution responsive orders.(b)Time delay requirement for required transactions on an order book - (1)Time delay requirement. A swap execution facility shall require that a broker or dealer who seeks to either execute against its customer's order or execute two of its customers' orders against each other through the swap execution facility's Order Book, following some form of pre-arrangement or pre-negotiation of such orders, be subject to at least a 15 second time delay between the entry of those two orders into the Order Book, such that one side of the potential transaction is disclosed and made available to other market participants before the second side of the potential transaction, whether for the broker's or dealer's own account or for a second customer, is submitted for execution.(2)Adjustment of time delay requirement. A swap execution facility may adjust the time period of the 15 second time delay requirement described in paragraph (b)(1) of this section, based upon a swap's liquidity or other product-specific considerations; however, the time delay shall be set for a sufficient period of time so that an order is exposed to the market and other market participants have a meaningful opportunity to execute against such order.(c)Execution methods for permitted transactions.(1)Permitted transaction means any transaction not involving a swap that is subject to the trade execution requirement in section 2(h)(8) of the Act.(2)Execution methods. A swap execution facility may offer any method of execution for each Permitted Transaction.(d)Exceptions to required methods of execution for package transactions.(1) For purposes of this paragraph, a package transaction consists of two or more component transactions executed between two or more counterparties where: (i) At least one component transaction is a Required Transaction;(ii) Execution of each component transaction is contingent upon the execution of all other component transactions; and(iii) The component transactions are priced or quoted together as one economic transaction with simultaneous or near-simultaneous execution of all components.(2) A Required Transaction that is executed as a component of a package transaction that includes a component swap that is subject exclusively to the Commission's jurisdiction, but is not subject to the clearing requirement under section 2(h)(1)(A) of the Act, may be executed on a swap execution facility in accordance with paragraph (c)(2) of this section as if it were a Permitted Transaction;(3) A Required Transaction that is executed as a component of a package transaction that includes a component that is not a swap, as defined under section 1a(47) of the Act, may be executed on a swap execution facility in accordance with paragraph (c)(2) of this section as if it were a Permitted Transaction. This provision shall not apply to:(i) A Required Transaction that is executed as a component of a package transaction in which all other non-swap components are U.S. Treasury securities;(ii) A Required Transaction that is executed as a component of a package transaction in which all other non-swap components are contracts for the purchase or sale of a commodity for future delivery;(iii) A Required Transaction that is executed as a component of a package transaction in which all other non-swap components are agency mortgage-backed securities; and(iv) A Required Transaction that is executed as a component of a package transaction that includes a component transaction that is the issuance of a bond in a primary market.(4) A Required Transaction that is executed as a component of a package transaction that includes a component swap that is not exclusively subject to the Commission's jurisdiction may be executed on a swap execution facility in accordance with paragraph (c)(2) of this section as if it were a Permitted Transaction.(e)Resolution of operational and clerical error trades.(1) As used in this paragraph: (i)Correcting trade means a trade executed and submitted for clearing to a registered derivatives clearing organization, or a derivatives clearing organization that the Commission has determined is exempt from registration, with the same terms and conditions as an error trade other than any corrections to any operational or clerical error and the time of execution.(ii)Error trade means any trade executed on or subject to the rules of a swap execution facility that contains an operational or clerical error.(iii)Offsetting trade means a trade executed and submitted for clearing to a registered derivatives clearing organization, or a derivatives clearing organization that the Commission has determined is exempt from registration, with terms and conditions that economically reverse an error trade that was accepted for clearing.(2)Execution of correcting trades and offsetting trades.(i) A swap execution facility shall maintain rules and procedures that facilitate the resolution of error trades. Such rules shall be fair, transparent, and consistent; allow for timely resolution; require market participants to provide prompt notice of an error trade-and, as applicable, offsetting and correcting trades-to the swap execution facility; and permit market participants to:(A) Execute a correcting trade, in accordance with paragraph (c)(2) of this section, regardless of whether it is a Required or Permitted Transaction, for an error trade that has been rejected from clearing as soon as technologically practicable, but no later than one hour after a registered derivatives clearing organization, or a derivatives clearing organization that the Commission has determined is exempt from registration, provides notice of the rejection; or(B) Execute an offsetting trade and a correcting trade, in accordance with paragraph (c)(2) of this section, regardless of whether it is a Required or Permitted Transaction, for an error trade that was accepted for clearing as soon as technologically practicable, but no later than three days after the error trade was accepted for clearing at a derivatives clearing organization or a derivatives clearing organization that the Commission has determined is exempt from registration.(ii) If a correcting trade is rejected from clearing, then a swap execution facility shall not allow the counterparties to execute another correcting trade.(f)Counterparty anonymity.(1) Except as otherwise required under the Act or the Commission's regulations, a swap execution facility shall not directly or indirectly, including through a third-party service provider, disclose the identity of a counterparty to a swap that is executed anonymously and intended to be cleared.(2) A swap execution facility shall establish and enforce rules that prohibit any person from directly or indirectly, including through a third-party service provider, disclosing the identity of a counterparty to a swap that is executed anonymously and intended to be cleared.(3) For purposes of paragraphs (f)(1) and (2) of this section, "executed anonymously" shall include a swap that is pre-arranged or pre-negotiated anonymously, including by a participant of the swap execution facility.(4) For a package transaction that includes a component transaction that is not a swap intended to be cleared, disclosing the identity of a counterparty shall not violate paragraph (f)(1) or (2) of this section. For purposes of this paragraph, a "package transaction" consists of two or more component transactions executed between two or more counterparties where: (i) Execution of each component transaction is contingent upon the execution of all other component transactions; and(ii) The component transactions are priced or quoted together as one economic transaction with simultaneous or near-simultaneous execution of all components. 78 FR 33582 , June 4, 2013, as amended at 85 FR 44707 , July 24, 2020; 85 FR 82329 , Dec. 18, 2020 85 FR 44707 , 9/22/2020; 85 FR 82329 , 2/16/2021
