RE: Modifications to the NEX SEF Fee Schedule for the Renewal of LATAM EBS NDF 

Connectivity Incentive Program and Expiration of the EBS on-SEF UK/US Crossover 

Market Maker Program

NEX SEF Submission No. 23-441

To Whom It May Concern:

Pursuant to Section 5c(c) of the Commodity Exchange Act (“CEA”) and Section 40.6(a) of the regulations of the 

Commodity Futures Trading Commission (“CFTC” or “Commission”), NEX SEF Limited (“NEX SEF”) hereby notifies 

the Commission of modifications to NEX SEF’s Fee Schedule for the renewal of the LATAM EBS NDF Connectivity

Incentive Program and expiration of the EBS on-SEF UK/US Crossover Market Maker Program (collectively, the 

“Programs”). These modifications will be effective on November 1, 2023.

The Programs are set forth in Appendix A, attached under separate cover, with additions underlined and deletions 

overstruck. A clean version of the Programs is set forth in Appendix B, attached under separate cover. A request for 

confidential treatment of these changes is being simultaneously submitted to the Commission and a copy of that request 

for confidential treatment is included with this submission.

NEX SEF has reviewed the swap execution facility core principles (“Core Principles”) as set forth in the CEA and has 

determined that the Program complies with the requirements of impartial access in Core Principle 2 and Commission 

Regulation 37.202 because all fees and any discounts will be applied in an impartial, fair, and non-discriminatory 

manner, and the Program will be made transparent to all participants. In compliance with Core Principle 2 and 

Commission Regulation 37.200, the Program does not incentivize manipulative trading or market abuse or impact NEX 

SEF’s ability to perform its trade practice and market surveillance obligations under the Act, and Market Regulation 

staff will continue to monitor trading to prevent manipulative trading and market abuse. The Program also complies with 

the requirements for monitoring and trade processing in Core Principle 4 and Commission Regulation 37.401, and the 

recordkeeping and reporting requirements in Core Principle 10 and Commission Regulations 37.1000 and 37.1001. 

NEX SEF has implemented systems to track the program participants’ transactions to ensure proper fee discounts are 

applied.

NEX SEF certifies that the Program complies with the requirements of the CEA and the rules and regulations 

promulgated thereunder. There were no substantive opposing views to this proposal. 

NEX SEF certifies that this submission has been concurrently posted on its website at 

http://www.cmegroup.com/market-regulation/rule-filings.html.
