Portugal's MiCA Transition Period Sunsets 1 July 2026 — Crypto-Asset Service Providers Migrate to BdP and CMVM Dual Supervision and the Anti-Money-Laundering Frame Treats Them as Financial Entities

The clock on Portugal's MiCA (Markets in Crypto-Assets Regulation) transition window winds down to its final four weeks. From 1 July 2026, crypto-asset service providers (CASPs) that were active in Portugal under the prior Banco de Portugal (BdP) registration frame must either hold a full MiCA authorisation issued by the new dual supervisor or stop providing services to Portuguese clients. The regime overhaul, set in EU Regulation 2023/1114 and transposed into the Portuguese system by Decree-Law 66/2025, replaces the pre-MiCA anti-money-laundering registration with a comprehensive prudential and conduct authorisation that pulls crypto firms inside the regulated financial perimeter.

The supervisory split between BdP and the CMVM (Comissão do Mercado de Valores Mobiliários, Securities Market Commission) divides along function rather than firm. The BdP handles prudential supervision — capital, governance, risk management, recovery and resolution planning — and is the lead authority for issuers of asset-referenced tokens (ARTs) and electronic-money tokens (EMTs). The CMVM runs the conduct-of-business supervision — disclosure, advertising, suitability, market-abuse detection — and is the lead authority for service providers, including exchanges, custodians and order-execution venues. Both authorities can fine up to €5 million or, where higher, five times the gain or twice the loss avoided.

On the operational side, the AML reframe is the bite that touches the largest universe of firms. From 1 July, crypto-asset service providers headquartered in Portugal are classified as financial entities for the purposes of the Lei 83/2017 anti-money-laundering and counter-terrorism-financing regime. That triggers full Know-Your-Customer obligations, transaction monitoring, suspicious-activity reporting to the Unidade de Informação Financeira (UIF, Financial Intelligence Unit) and beneficial-owner verification at the same intensity that applies to banks and payment institutions. The 1,000-euro per-transaction cap that the EU AML package introduces on cash payments runs alongside the new regime, with proportionate adjustments for crypto-to-fiat conversion at scale.

For consumers, the most visible change is the white-list. Only entities authorised under MiCA — by the BdP-CMVM tandem in Portugal or under the passport regime by their home-state regulator — can market crypto-asset services to Portuguese residents. The CMVM has signalled it will publish and maintain a real-time public register of authorised CASPs accessible through the supervisor's website, mirroring the existing intermediário financeiro registry for traditional brokers. Marketing of unauthorised platforms — including by influencers and affiliates — falls inside the same prohibition, with the CMVM holding the publicidade enforcement competence already exercised on contracts-for-difference and PRIIPs products.

The grace-period structure means that firms that were providing services before 30 December 2024 under the prior BdP registration can continue to operate up to 1 July 2026 while their MiCA application sits in queue, provided they have filed by the deadline. After 1 July, an unauthorised firm faces immediate cease-and-desist orders from the CMVM and potential criminal referral on the unauthorised intermediation count under the Código dos Valores Mobiliários (CVM). The Portuguese transition has run on a tighter timetable than the EU baseline — many Member States extended the grace window to 30 December 2026 — and the BdP has publicly defended the 1 July cut to discourage regulatory arbitrage by firms passporting in from longer-window jurisdictions.

The market impact is material. Portugal has been one of Europe's higher-density crypto-trading jurisdictions in retail terms, anchored by the personal-income-tax frame that taxes crypto gains held more than 365 days at 0% and shorter-window gains at the 28% capital-gains rate. The MiCA-driven consolidation will favour the largest passport-in platforms with EU-wide licensing capacity over smaller domestic operators, and is expected to thin the local CASP roster between July and year-end.
