ESMA Sets a July 1 Stop for Crypto Firms Without MiCA Approval

The European Securities and Markets Authority published a public statement on June 23 setting out what crypto firms may and may not do once MiCA's transitional arrangements expire on July 1. The document, numbered ESMA75-113276571-1710, is addressed to crypto-asset service providers that have not been authorized under the Markets in Crypto-Assets Regulation but have kept operating under grandfathering, the national transitional regimes that let existing providers continue serving clients while their authorization applications were pending. Those regimes end on the same date across the European Union. ESMA's instruction to firms that have not completed authorization is to stop taking on new business immediately, and to treat what remains as a wind-down rather than a business.

The Deadline: One Date Across the Whole Union

Grandfathering allowed a firm already providing crypto-asset services in a member state to keep providing them while its application sat with a national competent authority. On July 1 that bridge is removed for everyone at once. There is no residual national permission to fall back on and no jurisdiction inside the bloc where an unauthorized provider can continue serving EU clients on the old basis. For an operator whose file is still open on the deadline, the practical position on July 1 is not a narrower license but the absence of one.

The Instruction: Stop Onboarding, Stop Marketing

ESMA's statement is specific about the conduct it expects. Providers without authorization must "immediately stop onboarding new EU clients, refrain from opening new client relationships or accounts, and cease marketing activities." That covers the acquisition side of the business in its entirety: no new accounts, no new relationships with existing counterparties, and no promotion of services into the bloc. What survives the deadline is confined to letting existing clients get out in an orderly way. According to ESMA, the residual activity permitted is limited to:

• Sales, transfers, reallocation and the closure of existing positions.
• Custody, but only for as long as an orderly exit requires.
• Full anti-money-laundering and counter-terrorist-financing compliance, maintained throughout the wind-down.

The third item is the one most easily underestimated. A firm that has stopped acquiring clients and is running off a book still carries the same screening, monitoring and reporting obligations it had while growing, and it carries them while its revenue base shrinks. Custody is framed as a function with an end date rather than a service, which means the wind-down has to be planned against the operational reality of returning or transferring client assets.

Enforcement: National Authorities Engaging Firms Directly

ESMA set out how supervision will work after the transition closes. National competent authorities will engage affected entities directly, rather than waiting for firms to self-identify, and will coordinate their monitoring of unauthorized providers operating across borders. ESMA also said coordinated action may follow once the transitional period has ended. The cross-border element is the part that changes the calculation for operators. A provider serving clients in several member states from one base has, until now, faced supervisors working through separate national files; a coordinated effort treats that footprint as one object, and an action in one jurisdiction reads across to the rest.

What Changes on July 1

For a firm that finishes authorization in time, the deadline is administrative. For one that does not, it converts a going concern into a run-off book overnight: client numbers can only fall, custody balances can only be returned or transferred, and the cost of compliance does not fall with them. The statement gives no discretion to extend, and its language on marketing removes the option of keeping a European brand presence warm while an application completes. What is not yet visible is how many providers are in that position on July 1, or how quickly national authorities move from direct engagement to the coordinated action ESMA has flagged. The first weeks of July will show whether the deadline functions as an administrative reset or as the point at which a set of firms leaves the EU market entirely.
