Trading systems that offer the use of non-firm trading interest and provide protocols to bring

summary

The U.S. SEC proposed regulatory changes to extend investor protections under Regulation ATS and Regulation SCI to Communication Protocol Systems and ATSs trading U.S. government securities, closing a regulatory gap but not alleging any fraud or misconduct.

paragraph

The U.S. Securities and Exchange Commission proposed amending Regulation ATS to require ATSs trading U.S. government securities and repurchase agreements to comply with investor protection rules previously exempted, and to redefine 'exchange' to include Communication Protocol Systems, forcing them to register or comply with ATS rules. The proposal also extends Regulation SCI’s systems integrity standards to high-volume ATSs—those with 5% or more of daily trading volume in Treasury or Agency securities—and applies the Fair Access Rule to those with 3%–5% market share. Covered entities must file public disclosures via Form ATS-N, adopt non-discriminatory access standards, and modernize reporting through EDGAR to ensure fair and orderly markets.

narrative

The U.S. Securities and Exchange Commission proposed regulatory reforms to address a longstanding gap in investor protections for Communication Protocol Systems and Alternative Trading Systems (ATSs) that trade U.S. government securities and repurchase agreements. These systems, which function like exchanges but were previously exempt from Regulation ATS, would now be required to register as exchanges or comply with ATS rules, including becoming members of Self-Regulatory Organizations. The proposal also extends Regulation SCI’s systems integrity requirements to ATSs with 5% or more of the daily trading volume in U.S. Treasury or Agency securities, ensuring operational resilience. Additionally, the Fair Access Rule would apply to ATSs with 3%–5% market share, mandating fair, non-discriminatory access standards and transparent justifications for access policies. All covered entities must file public disclosures via a revised Form ATS-N on EDGAR, including details on operations, liquidity providers, and surveillance practices. The SEC aims to level the regulatory playing field across similar trading venues and enhance market fairness without alleging any fraud, misconduct, or enforcement action. The proposal does not involve financial penalties or accused individuals, but rather seeks to modernize oversight to match the evolving structure of securities markets.

Why This Matters
Trading  systems  that  offer  the  use  of  non-firm  trading  interest  and  provide  protocols  to  bring
together  buyers  and  sellers  of  securities  (Communication  Protocol  Systems)  have  evolved  to
function similarly to marketplaces operated by registered exchanges and ATSs  and have become
important venues for bringing together buyers and sellers for various types of securities. Because
Communication Protocol Systems do not fall within the definition of “exchange” and are thus not
required  to  register  as  exchanges,  they  are  not  required  to  comply  with  the  same  federal
securities laws and regulations applicable to registered exchanges or ATSs. As a result, market
participants who use these systems are not availed to the same investor protection and fair and
orderly market principles that apply to today’s registered exchanges and ATSs. This proposal is
designed  to  address  this  regulatory  gap  and  the  current  disparities  that  affect  competitive
balances among like marketplaces for securities.
Despite  the  critical  role  of  government  securities  in  the  U.S.  and  global  economy,  Regulation
ATS has limited application to ATSs   that trade U.S. government securities. This proposal would
apply the investor protections and fair and orderly market principles of Regulation ATS to ATSs
that  trade  U.S.  government  securities  or  repurchase  and  reverse  repurchase  agreements  on
government  securities.  The  proposal  would  also  apply  the  systems  integrity  provisions  of
Regulation SCI to certain ATSs that trade government securities.

How This Rule Applies
The proposed amendments would no longer exempt from Regulation ATS those ATSs that limit
securities activities to government securities or repurchase agreements or reverse repurchase
agreements on government securities and register as broker-dealers or are banks. The proposed
amendments  also  would include  Communication  Protocol  Systems  within  the  definition  of
“exchange”  so  that  Communication  Protocol  Systems  that  choose  to  operate  as  ATSs   would
need to comply with the existing Regulation ATS provisions that protect investors and promote
fair and orderly markets.

 The Securities and Exchange Commission proposed to:
● Expand Regulation ATS for alternative trading systems (ATS) that trade government securities,
NMS stock, and other securities;
● Extend Regulation SCI to ATSs that trade government securities; and
● Amend the SEC rule regarding the definition of an “exchange” to address a regulatory gap.

The proposed amendments would apply the Fair Access Rule to Government Securities ATSs
that,  during  at  least  four  of  the  preceding  six  calendar  months,  had:  (1)  for  U.S.  Treasury
Securities, three percent or more of the average weekly dollar volume traded in the U.S, (2) for
Agency securities, five percent or more of the average daily dollar volume traded in the U.S.
The  proposed  amendments  would  also  extend  the  requirements  of  Regulation  SCI  to
Government Securities ATSs that during at least four of the preceding six calendar months had
five percent or more of the average daily dollar volume traded in the U.S. for either U.S. Treasury
Securities or Agency securities.

What’s Required
For Communication Protocol Systems: Register as an exchange or operate under the ATS
exemption,  which  includes  registering  as  a  broker-dealer,  including  becoming  a  member  of  a
Self-Regulatory Organization, and complying with Regulation ATS.
For Government Securities ATSs:
• File a public Form ATS-N through EDGAR that would disclose information about their manner
of operations and the ATS-related activities of the registered broker-dealer or government
securities broker or dealer that operates the ATS and its affiliates.
• For those  currently  operating  pursuant  to  the  exemption  for  certain  government  securities
ATSs, comply with the other applicable provisions of Regulation ATS.
For existing NMS Stock ATSs:
• File an amendment to their existing disclosures in accordance with a revised Form ATS-N,
which includes questions about the ATS’s interaction with related markets, liquidity providers,
and activities the ATS undertakes to surveil and monitor its market.
• Report changes to fee disclosures on Form ATS-N no later than the date they make a fee
change.
For ATSs that trade all types of securities:
• Modernize  both  Form  ATS  and  ATS-R and electronically file  them  with  the  SEC  through
EDGAR.
• If subject to the Fair Access Rule, ensure that they meet the minimum requirements for the
reasonable written standards for granting, limiting, and denying access to ATS services that
must be established, and applied, and among other things, justify why each standard is fair
and not unreasonably discriminatory.
