          - [Release No. 34-92792; File Nos. SR-MIAX-2021-29, SR-EMERALD-2021-22, SR-PEARL-2021-30]

## I. Introduction

                    On July 1, 2021, Miami International Securities Exchange, LLC (“MIAX”), MIAX Emerald, LLC (“MIAX Emerald), and MIAX PEARL, LLC (“MIAX Pearl”) (each an “Exchange;” collectively, the “Exchanges”) each filed with the Securities and Exchange Commission (“Commission”) pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to increase fees for purge ports. Each proposed rule change was immediately effective upon filing with the Commission pursuant to Section 19(b)(3)(A) of the Act.[3]                                          The proposed rule changes were published for comment in the                     **Federal Register**                     on July 15, 2021.[4]                                          The Commission has received comment on the proposals.[5]                                          Pursuant to Section 19(b)(3)(C) of the Act,[6]                                          the Commission is hereby: (1) Temporarily suspending File Nos. SR-MIAX-2021-29, SR-EMERALD-2021-22, and SR-PEARL-2021-30; and (2) instituting proceedings to determine whether to approve or disapprove File Nos. SR-MIAX-2021-29, SR-EMERALD-2021-22, and SR-PEARL-2021-30.                

## II. Description of the Proposed Rule Changes

                    Each Exchange currently provides certain of its members the option to purchase purge ports to assist in their quoting activity.[7]                                          Purge ports provide the ability to send quote purge messages to an Exchange's system.[8]                                          Each Exchange offers purge ports as a package; a member has the option to receive up to two purge ports per matching engine to which it connects.[9]                                          MIAX has 24 matching engines, and thus a member may receive up to 48 purge ports on MIAX.[10]                                          MIAX Emerald and MIAX Pearl each have 12 matching engines, and thus a member may receive up to 24 purge ports on these Exchanges.[11] 

MIAX and MIAX Emerald previously charged a flat fee of $1,500 per month for purge ports, and MIAX Pearl previously charged a flat fee of $750 per month for purge ports, regardless of the number of matching engines to which a member connected and consequently regardless of the number of purge ports allocated to the member. Each Exchange proposes to increase the flat monthly fee to $7,500.

## III. Suspension of the Proposed Rule Changes

                    Pursuant to Section 19(b)(3)(C) of the Act,[12]                                          at any time within 60 days of the date of filing of an immediately effective proposed rule change pursuant to Section 19(b)(1) of the Act,[13]                                          the Commission summarily may temporarily suspend the change in the rules of a self-regulatory organization (“SRO”) if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. As described below, the Commission believes a temporary suspension of the proposed rule changes is necessary and appropriate to allow for additional analysis of the proposed rule changes' consistency with the Act and the rules thereunder.                

                    When an exchange files a proposed rule change with the Commission, including fee filings, it is required to provide a statement supporting the proposal's basis under the Act and the rules and regulations thereunder applicable to the exchange.[14]                                          The instructions to Form 19b-4, on which exchanges file their proposed rule changes, specify that such statement “should be sufficiently detailed and specific to support a finding that the proposed rule change is consistent with [those] requirements.” [15] 

                    Section 6 of the Act, including Sections 6(b)(4), (5), and (8), requires, among other things, that the rules of an exchange: (1) Provide for the equitable allocation of reasonable fees among members, issuers, and other persons using the exchange's facilities; [16]                                          (2) be designed to perfect the mechanism of a free and open market and a national market system and to protect investors and the public interest, and not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers; [17]                                          and (3) not impose any burden on competition                           ( print page 49385)                        not necessary or appropriate in furtherance of the purposes of the Act.[18] 

                    In support of their proposals, the Exchanges state that the use of purge ports is completely optional, and no options market participant is required by rule, regulation, or competitive forces to use them.[19]                                          The Exchanges explain that members can use other protocols to purge or cancel messages, and that purge ports were designed as an optional service to enable firms to manage their quoting risk and meet their heightened quoting obligations.[20]                                          The Exchanges state that they are not aware of any reason why a market participant could not simply drop its purge ports if the Exchanges were to establish unreasonable prices for purge ports that, in the determination of such market participant, did not make business or economic sense for such participant.[21] 

                    The Exchanges also state that they operate in a highly competitive environment, and if an exchange sets non-transaction fees that are too high for its relevant marketplace, market participants can choose to no longer access that particular exchange.[22] 

                    The Exchanges further state that the increased monthly flat fee for purge ports is competitive with fees charged by other exchanges that offer comparable purge port services.[23]                                          The Exchanges state that they have historically undercharged for purge ports as compared to other exchanges, and that the proposed monthly fee increase would bring the Exchanges' fees more in line with that of other options exchanges.[24]                                          The Exchanges argue that, when calculated on a per purge port basis, other exchanges charge higher monthly fees. MIAX states that, assuming a member receives 48 purge ports (two per each of its 24 matching engines), this results in a cost of $156.25 per purge port ($7,500 divided by 48).[25]                                          MIAX Emerald and MIAX Pearl state that, assuming a member receives 24 purge ports (two per each of their 12 matching engines), this results in a cost of $312.50 per purge port ($7,500 divided by 24).[26]                                          The Exchanges state that Cboe BZX Exchange, Inc. (“BZX”), Cboe EDGX Exchange, Inc. (“EDGX”), Cboe Exchange, Inc. (“Cboe”), and Nasdaq GEMX, LLC (“GEMX”) charge higher monthly per purge port fees of $750, $750, $850, and $1,250, respectively.[27] 

                    The one comment letter received to date challenges several of the Exchanges' assertions.[28]                                          The commenter states that the Exchanges' argument that the proposed $7,500 monthly fee is lower on a per purge port basis than the fees assessed by other exchanges (BZX, EDGX, Cboe, GEMX) is disingenuous, because each of these other exchanges has one matching engine, and thus market participants require only two purge ports on each of these exchanges, resulting in significantly lower fees when calculated on a monthly basis.[29]                                          The commenter also states that the Exchanges' argument that purge ports are optional functionality, which members are free to drop if priced too high, is without merit.[30]                                          The commenter asserts that the Exchanges know that market makers have no choice but to absorb these fees so as not to imperil their business with stale quotes.[31]                                          The commenter further states that the Exchanges did not provide any justification for the fee increase itself; and that the Exchanges likely cannot assert that the cost of maintaining purge ports has increased at all, let alone five-fold.[32] 

                    In temporarily suspending the Exchanges' proposed rule changes, the Commission intends to further consider whether the proposed purge port fees are consistent with the statutory requirements applicable to a national securities exchange under the Act. In particular, the Commission will consider whether the proposed rule changes satisfy the standards under the Act and the rules thereunder requiring, among other things, that an exchange's rules provide for the equitable allocation of reasonable fees among members, issuers, and other persons using its facilities; are designed to perfect the mechanism of a free and open market and a national market system and to protect investors and the public interest, and are not designed to permit unfair discrimination between customers, issuers, brokers, or dealers; and do not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act.[33] 

                    Therefore, the Commission finds that it is appropriate in the public interest, for the protection of investors, and otherwise in furtherance of the purposes of the Act, to temporarily suspend the proposed rule changes.[34] 

## IV. Proceedings To Determine Whether To Approve or Disapprove the Proposed Rule Changes

                    In addition to temporarily suspending the proposal, the Commission also hereby institutes proceedings pursuant to Sections 19(b)(3)(C) [35]                                          and 19(b)(2)(B) of the Act [36]                                          to determine whether the Exchanges' proposed rule changes should be approved or disapproved. Institution of proceedings does not indicate that the Commission has reached any conclusions with respect to any of the issues involved. Rather, the Commission seeks and encourages interested persons to provide additional comment on the proposed rule changes to inform the Commission's analysis of whether to approve or disapprove the proposed rule changes.                

                    Pursuant to Section 19(b)(2)(B) of the Act,[37]                                          the Commission is providing notice of the grounds for possible disapproval under consideration:                
    - Whether the Exchanges have demonstrated how the proposed fees are consistent with Section 6(b)(4) of the Act, which requires that the rules of a national securities exchange “provide for the equitable allocation of reasonable dues, fees, and other charges among its members and issuers and other persons using its facilities”;  [38]  
    - Whether the Exchanges have demonstrated how the proposed fees are consistent with Section 6(b)(5) of the Act, which requires, among other things, that the rules of a national securities exchange be designed to “perfect the mechanism of a free and open market and a national market       ( print page 49386)                          system” and “protect investors and the public interest,” and not be “designed to permit unfair discrimination between customers, issuers, brokers, or dealers”;  [39]                                           and                
    - Whether the Exchanges have demonstrated how the proposed fees are consistent with Section 6(b)(8) of the Act, which requires that the rules of a national securities exchange “not impose any burden on competition not necessary or appropriate in furtherance of the purposes of [the Act].”  [40]  

                    As discussed in Section III above, the Exchanges made various arguments in support of the proposal, and the Commission received comment disputing the Exchanges' arguments and expressing concerns regarding the proposal.[41]                                          In particular, the commenter argues that the Exchanges did not provide sufficient information to establish that the proposed fees are consistent with the Act and the rules thereunder.[42] 

                    Under the Commission's Rules of Practice, the “burden to demonstrate that a proposed rule change is consistent with the [Act] and the rules and regulations issued thereunder . . . is on the [SRO] that proposed the rule change.” [43]                                          The description of a proposed rule change, its purpose and operation, its effect, and a legal analysis of its consistency with applicable requirements must all be sufficiently detailed and specific to support an affirmative Commission finding,[44]                                          and any failure of an SRO to provide this information may result in the Commission not having a sufficient basis to make an affirmative finding that a proposed rule change is consistent with the Act and the applicable rules and regulations.[45] 

                    The Commission is instituting proceedings to allow for additional consideration and comment on the issues raised herein, including as to whether the proposal is consistent with the Act, and specifically, with its requirements that the rules of a national securities exchange provide for the equitable allocation of reasonable dues, fees, and other charges among its members, issuers, and other persons using its facilities; are designed to perfect the mechanism of a free and open market and a national market system, and to protect investors and the public interest; are not designed to permit unfair discrimination between customers, issuers, brokers, or dealers; and do not impose a burden on competition not necessary or appropriate in furtherance of the purposes of the Act; [46]                                          as well as any other provision of the Act, or the rules and regulations thereunder.                

## V. Commission's Solicitation of Comments

                    The Commission requests written views, data, and arguments with respect to the concerns identified above as well as any other relevant concerns. Such comments should be submitted by September 23, 2021. Rebuttal comments should be submitted by October 7, 2021. Although there do not appear to be any issues relevant to approval or disapproval that would be facilitated by an oral presentation of views, data, and arguments, the Commission will consider, pursuant to Rule 19b-4, any request for an opportunity to make an oral presentation.[47]
