Dear Mr. Zsolt,

Please accept our apologies for the delay in responding to your e-mails addressed to the National bank of Belgium.

While we fully acknowledge your concerns, we regret that we are unable to respond to individual enquiries regarding our supervisory actions.

That said, we can confirm that Wise Europe is authorized to provide Belgian (BE) IBAN accounts to customers across the EEA. Any “additional IBANs” – such as Hungarian IBANs- are likely to be so-called “virtual” IBANs, which are used as “routing identifiers” re-directing the funds to an underlying master account held either by Wise Europe S.A. or another entity of the Wise group.

As the supervisory authority for Wise Europe S.A., we have undertaken a range of measures to ensure the traceability of funds transiting through such virtual IBAN arrangements, as well as their proper segregation within the master accounts held on the books of Wise Europe S.A..

However, virtual IBAN arrangements are not -yet- subject to a harmonized regulatory framework at the European level, and they indeed presently fall outside the scope of reporting to central account registries. This will change after the entry into force of the AMLD VI. While this situation gives rise to legal and enforcement challenges, this does not constitute a regulatory gap that the National Bank of Belgium can address within the limits of its mandate.

Considering the above, we strongly encourage you to share any concrete information you may have regarding the potential misuse of these accounts with the competent Hungarian judicial authorities, who can take appropriate action, where indicated, with their Belgian counterparts.

With kind regards,
AML/CFT supervision team
National Bank of Belgium
