The Dutch central bank (DNB) has published an enforcement decision requiring investment firm Zonnepanelendelen B.V. (ZPD) to correct a capital shortfall or face penalty payments. The order was imposed on May 8, 2026. ZPD subsequently restored compliance within the prescribed deadline, so no penalty payments became payable. ZPD had incorrectly deducted certain costs when calculating its fixed overheads requirement. Correcting the calculation revealed a substantially higher capital requirement, leaving the firm with insufficient own funds since at least Dec. 31, 2025. This breached the Investment Firms Regulation, which requires investment firms to maintain sufficient own funds at all times. DNB imposed the order after the shortfall remained unresolved despite an earlier opportunity to correct it. Additional information and revised financial data submitted after the order demonstrated that ZPD had remedied the deficit within the deadline.
