The Commodity Futures Trading Commission (CFTC) is proposing to eliminate a longstanding requirement that swap execution facilities maintain an order book for certain swaps—even where market participants rarely use it.

On August 20, 2026, the CFTC published a Notice of Proposed Rulemaking proposing amendments to CFTC Regulation § 37.3(a)(2) that would remove the order book requirement for permitted transactions traded on swap execution facilities (SEFs).

The proposal reflects a broader regulatory question: when a particular market structure is technically available but rarely used, should regulated platforms still be required to maintain it?

What Is Changing?

Under the existing framework, SEFs are generally required to provide an order book for swaps they list for trading. The CFTC's proposal would eliminate that requirement for permitted transactions, allowing SEFs to offer those transactions without maintaining an order book.

Permitted transactions are distinct from required transactions, which remain subject to separate execution requirements. The proposal therefore does not eliminate the SEF order book framework altogether.

Instead, it targets a particular requirement that the CFTC believes may no longer provide sufficient regulatory or market benefit to justify its cost.

Why Is the CFTC Proposing the Change?

The CFTC explained that order books for permitted transactions have been rarely used by market participants, despite being available for swaps listed by SEFs.

The Commission's view is that requiring SEFs to maintain an execution method that market participants generally do not use may unnecessarily consume resources without meaningfully improving market functioning.

CFTC Chairman Michael S. Selig characterized the proposal as part of the agency's effort to apply what he called the "minimum effective dose of regulation."

Removing the requirement could allow SEFs to redirect resources and develop alternative execution methods that better fit the characteristics of the products traded on their platforms.

More Flexibility for SEFs

The practical significance of the proposal is greater flexibility in market design.

Rather than requiring every SEF to support an order book for permitted transactions, the proposed rule would allow individual facilities to determine which execution methods make sense for their markets and participants.

That flexibility could be particularly important as derivatives markets continue to evolve and electronic trading platforms experiment with different methods of liquidity formation, price discovery and trade execution.

Importantly, deregulation here does not mean deregulation of SEFs generally. SEFs would remain regulated trading facilities subject to the Commodity Exchange Act and applicable CFTC requirements. The proposal is narrower: it removes a specific execution-method mandate where the Commission has concluded that actual market usage does not justify maintaining it.

Why It Matters

For SEFs, the immediate benefit could be reduced operational and technological costs associated with maintaining an underused order book.

For market participants, the change could encourage platforms to develop execution models better suited to particular swap products rather than designing their systems around a regulatory requirement.

More broadly, the proposal signals the CFTC's willingness to reconsider rules where market practice has diverged from the assumptions underlying the original regulatory framework.

That approach could become increasingly relevant as derivatives markets incorporate new technologies, trading models and products.

What Happens Next?

The proposal is not yet final.

The CFTC is accepting public comments for 30 days following publication of the proposal in the Federal Register. Market participants, SEFs and other interested parties will therefore have an opportunity to weigh in on whether eliminating the order book requirement appropriately balances regulatory oversight with operational flexibility.

For SEFs and businesses operating in derivatives markets, the proposal is another reminder to monitor the CFTC's ongoing reassessment of market-structure requirements. Even relatively technical amendments can affect platform architecture, compliance obligations and the economics of operating regulated trading infrastructure.
