Its conclusion is clear: an EU trading platform may not pool its order book with a non-EU platform operated by an entity that is not authorised under MiCA.<\/p>\n

The Q&A is particularly relevant to international crypto groups that use a global order book to provide their EU and non-EU clients with access to the same liquidity.<\/p>\n

What has ESMA clarified?<\/h2>\n

A shared order book model allows two or more platforms to combine their buy and sell orders in a single order book. Orders submitted by clients of the participating platforms can consequently be matched against each other.<\/p>\n

Under Article 3(1)(18) MiCA, operating a trading platform for crypto-assets includes managing a multilateral system that brings together multiple third-party buying and selling interests in a manner that results in a contract. ESMA considers the management of an order book to be a fundamental part of operating such a system.<\/p>\n

According to ESMA, each entity operating an order book that forms part of the shared order book therefore provides the regulated service of operating a trading platform. Each operator must consequently be authorised under Article 63 MiCA or, where applicable, have submitted a notification under Article 60 MiCA.<\/p>\n

An EU-authorised CASP cannot therefore share its order book with a non-EU platform if the operator of that platform is not authorised or notified under MiCA. Such an arrangement would breach Article 59 MiCA and would result in the non-EU entity providing the service of operating a trading platform in the EU without the required authorisation.<\/p>\n

Why does this matter in practice?<\/h2>\n

Many international crypto groups use a shared or global order book to concentrate liquidity across different entities and jurisdictions. ESMA\u2019s interpretation means that an EU platform cannot participate in such an arrangement merely because the EU-facing entity itself holds a MiCA authorisation.<\/p>\n

The relevant question is who is involved in managing the shared order book. If an unauthorised non-EU entity operates one of the connected order books and orders from its clients can be matched with orders submitted through the EU platform, the model is not permitted.<\/p>\n

The fact that the entities belong to the same group does not change this conclusion. Nor can the issue necessarily be resolved by describing the non-EU entity as a technology or liquidity provider if that entity is, in substance, involved in operating the shared order book.<\/p>\n

The practical consequence may be significant. A CASP using a global order book may need to separate its EU order book from the order books operated by non-EU group entities. This can reduce the liquidity available through the EU platform and may require changes to its matching engine, order routing and group operating model.<\/p>\n

What should trading platforms do?<\/h2>\n

CASPs operating, or applying for authorisation to operate, a trading platform should establish:<\/p>\n

    \n
  • whether orders submitted through the EU platform are included in an order book shared with non-EU platforms;<\/li>\n
  • whether clients of different platforms can trade against each other through that shared order book;<\/li>\n
  • which entities manage the order book, matching process and applicable trading rules; and<\/li>\n
  • whether every entity involved in operating the shared order book is authorised or notified under MiCA.<\/li>\n<\/ul>\n

     <\/p>\n

    Where an unauthorised non-EU entity participates in managing the shared order book, the CASP will need to change the arrangement. In practice, this may require the EU platform to maintain a separate order book managed solely by an appropriately authorised or notified entity. The CASP should ensure that its technical architecture, contractual arrangements and MiCA application documentation accurately reflect that separation.<\/p>\n

    ESMA does not conclude that every form of shared infrastructure or liquidity arrangement is prohibited. The Q&A specifically addresses a model in which order books operated by an EU CASP and one or more unauthorised non-EU entities are merged. ESMA also expressly states that it has not assessed whether other types of shared order book arrangements comply with MiCA. Such alternative models therefore require a separate assessment.<\/p>\n

    Closing thought<\/h2>\n

    ESMA\u2019s Q&A places a clear regulatory limit on the use of global order books. An EU-authorised trading platform cannot share an order book with an unauthorised non-EU operator, because each entity managing the shared order book is itself considered to be operating a trading platform.<\/p>\n

    CASPs that rely on global liquidity should therefore determine whether their EU order book must be separated and, where necessary, adapt their platform architecture before commencing or continuing their MiCA-regulated services.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
