CFTC rule proposal would end SEF order book mandate for some swaps

The Commodity Futures Trading Commission has proposed to take a requirement out of its rulebook that, by the agency’s own account, market participants rarely use. On August 20, 2026, the Commission published a notice of proposed rulemaking that would amend Commission regulation 37.3(a)(2) and remove the order book requirement for permitted transactions on swap execution facilities. It is a narrow CFTC rule change with a clear statement of purpose, and it shows how the agency under Chairman Michael S. Selig describes its approach to swaps market structure.

What the proposal does

A swap execution facility, or SEF, is a trading platform registered with the CFTC under the swaps provisions of the Dodd-Frank Act. The statute directed standardized swaps toward regulated venues where bids and offers are visible to more than one counterparty, rather than leaving all swaps trading to bilateral negotiation. Rules written in the years after the 2010 law divided the swaps a SEF lists into two groups. Required transactions are those subject to the trade execution mandate, which must be executed on a regulated venue. Permitted transactions are the rest of the swaps a SEF lists, and they may be executed by other methods.

Under the current text of regulation 37.3(a)(2), a SEF must still make an order book available for permitted transactions, even though no one is compelled to use it. The proposal would eliminate that obligation. According to the Commission, order books for permitted transactions, unlike order books for required transactions, have been used rarely by market participants for swaps trading on SEFs, despite being available for every swap that a SEF lists.

The Commission’s release addresses only permitted transactions, and it draws the contrast with required transactions itself: order books for the latter, it says, see more use. Nothing in the announcement describes a change to the rules that apply to swaps under the trade execution mandate.

The stated rationale

Chairman Selig said the action continues the agency’s commitment to prescribing the “minimum effective dose of regulation” for market participants. In the Commission’s words, removing requirements that are excessive keeps the agency true to its principles-based approach. The release adds a more concrete point: eliminating the requirement gives SEFs flexibility to decide how to allocate their resources and could help spur development and innovation in execution methods better suited to the products they list.

The reasoning is a cost-and-use argument. An order book is a continuous, central limit order system that needs technology, surveillance and support. Where participants choose request-for-quote, voice-assisted or other negotiated methods for a swap, a book that sits idle is a fixed cost with little function. For a SEF that lists many swaps, the cost multiplies across the product set.

How an order book differs from the alternatives

In an order book, any eligible participant can post firm bids and offers and see those of others, and trades match by price and time priority, much as they do on a futures exchange. A request-for-quote system works differently: a participant asks selected dealers for prices on a specific trade and picks among the responses. Most swaps are customized by tenor, notional and start date, and many trade infrequently, so a single continuous book often has little to match. Dealers who make markets in them tend to prefer quoting on request, because a standing quote on a thinly traded instrument exposes them to being picked off when the market moves.

That difference explains why the Commission can say that books for permitted transactions are available but seldom used. Availability and liquidity are separate things. A rule that requires a platform to build and maintain a book guarantees the first and cannot create the second.

Who is affected

The most direct effect falls on SEF operators, which would be able to decide whether to run a book for permitted transactions. Dealers and buy-side firms trade the swaps in question, and the release says the books for them are rarely used. For a swap dealer or an asset manager, the proposed change should not alter how a permitted swap is executed today, since the order book is not the venue they use. It may alter what choices the platform offers over time, as operators decide what to build.

Competition among SEFs is a second effect to watch. A platform that stops maintaining an order book for permitted swaps may lower costs and could pass some of that on in fees or invest in other functionality. Another may choose to keep its book as a marketing point or to support price discovery. The proposal makes that a business decision instead of a compliance obligation.

Process and what to watch

The notice, which the Commission cites at 91 Federal Register 55030, will accept comments for 30 days after publication in the Federal Register. That window is where the substantive debate will occur. Several questions are likely to draw responses: whether any permitted transactions have enough order book activity that removal would reduce transparency, whether a SEF’s choice to drop an order book could affect the public availability of pricing data, and whether the Commission should preserve the requirement for particular swap classes.

The proposal also sits among other recent CFTC actions that trim or reset existing obligations, including a July final rule amending uncleared swap margin requirements for swap dealers not subject to prudential regulator margin rules and a July order sunsetting routine Part 20 large trader reporting for physical commodity swaps. Whether that logic holds for order books depends on the evidence commenters can supply, particularly data on how often the books for permitted transactions have been used and by whom.

For now the proposal is only that. No change takes effect until the Commission reviews the comments, decides whether to adopt a final rule, and publishes it. Until then, SEFs remain subject to the existing text.
