De Nederlandsche Bank (DNB) has imposed an order subject to penalty on IDSG Group B.V. (IDSG) after the firm failed to fully comply with a formal demand for information issued as part of DNB’s investigation. DNB sought the information to assess whether IDSG had invited repayable funds from the public without the required licence under Section 3:5 of the Financial Supervision Act. After IDSG did not respond to the demand, DNB concluded it had not met its statutory duty to cooperate under Section 5:20(1) of the General Administrative Law Act and issued the order on 3 September 2025, allowing 10 business days for compliance. IDSG did not provide all requested information and forfeited EUR 50,000 in penalties; the information provided was described as insufficient for DNB to rule out unlicensed activity and as obstructing the investigation. IDSG filed an objection to the order on 19 September 2025.
