Belgium FSMA CASP Authorisation 2026 — Practitioner Guide

A small jurisdiction in a strategic location

Belgium is not a high-volume EU CASP jurisdiction. The application pipeline is modest, the operating crypto-asset industry is smaller than in Lithuania, Cyprus, or even Portugal. But Belgium hosts something the volume-leaders do not — regulatory-policy proximity. The European Commission, ESMA’s permanent representation, the ECB’s banking-supervision arm, and the broader EU financial-services policy ecosystem all operate from Brussels.

For platforms that engage with EU-level policy, that need institutional-counterparty proximity, or that want a serious supervisor without the application-pipeline congestion of larger jurisdictions, Belgium deserves consideration as a passport hub. The FSMA is a professional, engaged supervisor with the time to dialogue substantively with applicants — a benefit the busier Tier 1 NCAs cannot consistently offer.

The supervisory architecture

Belgium designed its MiCA implementation around the FSMA as the primary CASP supervisor. The Law of 20 December 2024 amended the Belgian financial-services rulebook to designate the FSMA for:

• CASP authorisation under MiCA Article 63
• Conduct supervision under MiCA Articles 66-73
• Consumer protection and marketing communications
• ART/EMT issuer supervision under Title III/IV for non-credit-institution issuers

The National Bank of Belgium (NBB) retains:

• Credit-institution CASP supervision under MiCA Article 60 (banks notifying for crypto-asset services)
• AML supervision for financial institutions
• Macroprudential oversight where relevant

The Belgian FIU — CTIF-CFI — receives suspicious-transaction reports and engages directly with reporting CASPs on AML supervisory matters.

The FSMA register and its transition

Belgium operated a pre-MiCA crypto-asset register through the FSMA, established by Royal Decree of 8 February 2022. The register was AML-focused under the 5AMLD framework. Belgian VASPs on the register had to comply with AML and basic conduct requirements but were not substantively supervised in the way MiCA contemplates.

At MiCA application, the register wound down. Registered VASPs had 12 months — through end-2025 — to file a CASP authorisation application with the FSMA. The transitional regime granted operational continuity; it did not grant presumption of authorisation. By mid-2026 the steady-state regime is the live pathway.

What the FSMA looks for

The FSMA has published its CASP application guidance and supervisory expectations. The recurring themes:

Governance. A management body sized for the planned business with documented fit-and-proper assessments. Independent compliance and internal audit functions for larger files. Three-lines-of-defence framework. The FSMA’s investment-firm supervisory experience under MiFID II informs the expectations.

Substance in Belgium. Registered office in Belgium. At least one senior manager resident in Belgium. Compliance and operational-control functions staffed with Belgium-resident professionals. The FSMA does not accept letterbox arrangements — and given Belgium’s small application volume, supervisor attention to substance arrangements is closer than in higher-volume jurisdictions.

ICT and operational resilience. Framework consistent with DORA expectations. The FSMA has been active in DORA supervisory work and brings the same standards to CASP files. Cyber controls demonstrated effective; business continuity tested.

AML aligned with NBB and CTIF-CFI expectations. AML programme designed for NBB prudential-AML supervision and CTIF-CFI suspicious-transaction reporting. MLRO appointed with formal authority. KYC and transaction-monitoring infrastructure proportionate to the planned customer base.

Consumer protection in the relevant language. Client-facing materials in Dutch, French, or German for Belgian-targeted services — typically Dutch and French given the linguistic geography of the customer base. English-only consumer materials are not acceptable for Belgian-customer-facing services.

The trilingual filing reality

Belgium’s three official languages — Dutch, French, German — are accommodated by the FSMA for the formal application file. Applicants choose one language and produce a consistent dossier in that language. Mixed-language filings produce administrative friction.

For international groups, the language choice typically comes down to:

• French — most natural for Wallonia-based operations and French-speaking customer base, fits with the broader French-speaking financial-services ecosystem
• Dutch — most natural for Flanders-based operations and Dutch-speaking customer base, also fits with cross-border Dutch operations
• English — supplementary working translations accepted for supporting documentation, but the formal file must be in an official language

Plan the language choice with the legal counsel early. Switching mid-process is feasible but adds time and translation cost.

The realistic Belgian timeline

The FSMA’s MiCA application pipeline is small enough to permit close engagement with each file. The result is a process that runs at EU-median speed without notable acceleration or notable delay:

• Pre-filing preparation: 6-10 weeks
• FSMA pre-screen and completeness cycle: 4-6 weeks
• Active five-month clock: 16-22 weeks
• Decision and onboarding: 2-4 weeks

Six to nine months end-to-end is the working assumption. Smaller and simpler files for Class 1 services sometimes complete faster.

When Belgium is the right home supervisor

Belgium works well for:

• Platforms that engage with EU-level policy or institutional counterparties
• Operations with a Belgian or BeNeLux customer base
• International groups that want a serious supervisor without large-jurisdiction pipeline congestion
• Businesses with budget for Belgian substance (lower than Ireland, comparable to Netherlands)
• Operators that value supervisor dialogue and accessibility

Belgium is a weaker fit if the priority is the lowest-friction or fastest authorisation. The FSMA is not the fastest EU supervisor, the substance threshold is real, and the trilingual filing requirement adds operational complexity.

For a buyer triaging EU options: Belgium sits in the upper-middle tier alongside Netherlands and Portugal — significant supervisory expertise, professional and engaged regulator, modest application pipeline, and a strategic advantage in regulatory-policy proximity that the volume-leader jurisdictions cannot match.
