Europe's securities regulator has told national supervisors to ensure that authorised crypto firms stop providing services involving stablecoins that do not meet the European Union's crypto rules. Its opinion, published on 8 October, also sets a maximum three-month period for addressing remaining legacy exposures, with only tightly restricted services allowed during an orderly exit.
The European Securities and Markets Authority, or ESMA, is addressing services supplied to clients in the EU under the Markets in Crypto-Assets Regulation, known as MiCA. The opinion remains relevant as supervisors and providers assess existing holdings. It does not announce an Indian rule or identify particular stablecoins as non-compliant.
The 8 October announcement covers asset-referenced tokens and e-money tokens, two categories commonly described as stablecoins. ESMA's concern is whether tokens meet the conditions for lawful public offers or admission to trading in the EU, taking account of applicable exemptions and transitional arrangements.
The scope extends beyond trading platforms
The supervisory expectations cover the full range of MiCA crypto services. These include exchanging assets, executing or transmitting orders, placing tokens, advice, transfers, custody, administration and portfolio management, as well as running trading platforms. Supervisors are expected to examine services both individually and in combination.
That breadth matters because removing a token from a trading screen is only one possible change. ESMA says providers should put technical, contractual and organisational controls in place to prevent EU clients from acquiring or increasing positions in non-compliant tokens. The assessment therefore reaches how a service actually operates, rather than just how it is described.
The five-page opinion is addressed primarily to national competent authorities. It aims to make supervisory practice more consistent across the bloc. The document preserves the responsibilities of the European Banking Authority and relevant authorities for authorising and supervising stablecoin issuers, distinguishing those responsibilities from oversight of service providers. ESMA bases its position on providers' existing MiCA obligations, including the duty to act honestly, fairly and professionally in clients' best interests.
It also draws an important legal distinction. The opinion does not say that every service involving a stablecoin automatically amounts to a public offer or admission to trading. Instead, ESMA assesses whether keeping a non-compliant token available through an authorised provider is compatible with that provider's wider responsibilities.
Limited services for existing holdings
National supervisors may allow narrowly defined services where these are needed to wind down existing holdings without harming clients. The opinion lists liquidation, conversion, withdrawal, transfer and safekeeping. Such arrangements must be temporary, clearly explained to clients and subject to close supervision.
They cannot be used to support new acquisitions, promotion, active distribution or continuing market availability. Where supervisors identify legacy exposures, ESMA expects remediation as soon as possible and no later than three months after publication. The period is an outer limit for resolving those exposures, rather than permission to carry on normal business for three months.
ESMA argues that warnings and customer acknowledgements cannot replace the protections missing at issuer level. Its examples include applicable redemption rights, reserves or safeguarding arrangements, governance, disclosures and ongoing oversight. In the regulator's view, a service provider cannot adequately compensate for their absence simply by asking a customer to accept the risk.
How this fits the wider EU framework
MiCA regulates crypto assets outside existing EU financial-services legislation. ESMA's framework and register page separates authorised service providers from issuers of asset-referenced and e-money tokens. It also warns that publication of a crypto white paper in its register does not mean a competent authority has reviewed or approved that paper.
The stablecoin opinion is a different development from the EU Council's position on transferring supervision of significant cross-border crypto firms to ESMA. That legislative debate concerns which authority would supervise providers. This opinion concerns the services providers offer under the existing MiCA framework.
For comparison, Dalimss News has covered the US proposal on crypto custody for advisers and funds, which is a separate consultation. ESMA says it will monitor implementation of its stablecoin opinion with national authorities. The document does not publish a firm-by-firm timetable or a list of customer accounts affected. This report covers regulatory policy and is not investment advice.
