Analysis
What this data actually tells you
Financial and Insurance Activities in Belgium is supervised through a split system, sometimes called the ‘Twin Peaks’ model: the National Bank of Belgium (NBB) handles prudential supervision of credit institutions, insurers, stockbrokers and other financial organisations, while the FSMA (Financial Services and Markets Authority) oversees market conduct, investment firms, the financial information companies disseminate, and the products offered to consumers. Confirming a financial counterparty’s authorisation means checking the regulator matching its specific activity, since the two bodies cover genuinely different aspects of financial-sector oversight.
The crypto-asset sector faces a real, dated transition: existing registered virtual-currency exchange platforms in Belgium must move to full MiCAR authorisation by 1 July 2026, with the FSMA deciding CASP (crypto-asset service provider) applications under Article 63, and the transitional period for cross-border legacy CASPs ending on that date or upon authorisation, whichever comes first. For verification, the FSMA’s own public data portal is the authoritative source for confirming whether a Belgian financial-sector counterparty actually holds current authorisation, distinct from its ordinary commercial registration.

Who uses Belgium financial and insurance activities ownership data
The three checks this sector's data is most often run for.
FSMA/NBB dual-regulator check
Belgian financial supervision splits between the National Bank of Belgium (NBB, prudential supervision of banks, insurers and other financial institutions) and the FSMA (market conduct, investment firms, product oversight and supplementary pensions) — confirming a financial counterparty’s authorisation means checking the regulator relevant to its specific activity.
MiCAR CASP transition deadline
Existing registered virtual-currency exchange platforms in Belgium must transition to full MiCAR authorisation by 1 July 2026 — the FSMA decides CASP applications under Article 63, and cross-border legacy CASPs’ transitional period ends 1 July 2026 or upon authorisation, whichever comes first.
FSMA public data portal verification
The FSMA maintains a public data portal listing authorised entities — a real, checkable source for confirming a Belgian financial-sector counterparty’s actual regulatory status, separate from its commercial registration.
