Caixa Geral de Depósitos Takes Banco de Portugal to the Tribunal de Santarém Over a €9,000 Coima Tied to a Single Suspicious €10 Banknote at the Guimarães Branch
CGD is appealing a €9,000 Banco de Portugal coima tied to a single suspicious €10 banknote flagged at its Guimarães branch on 25 August 2023. The Tribunal de Concorrência, Regulação e Supervisão in Santarém will hear the case.
Caixa Geral de Depósitos (CGD) — the state-owned commercial bank that closed Friday's annual general meeting on a record €1.25 billion dividend to the Treasury — is now taking Banco de Portugal (Bank of Portugal) to court over a procedural coima (administrative fine) of €9,000. The dispute, first reported on Monday 1 June 2026, traces back to a single €10 banknote presented at the CGD branch in Guimarães on 25 August 2023. The case will be heard at the Tribunal de Concorrência, Regulação e Supervisão (Competition, Regulation and Supervision Court) sitting in Santarém, the specialist jurisdiction that ordinarily processes the Banco de Portugal's regulatory enforcement against the credit-institution stack.
The Underlying Inspection Trail
The Banco de Portugal field-inspection team — which under the Decreto-Lei 195/2007 framework is the supervisor for the cash-handling and counterfeit-detection regime applied to all credit institutions operating in Portugal — entered the CGD Guimarães branch on 25 August 2023 for a routine cash-cycle compliance check. The inspector flagged a single €10 note as potentially counterfeit. According to CGD's narrative, the branch's counter team had already suspected the note, performed a second validation, and concluded the note was fit for recirculation. The procedural defect is that the validation step was not documented in the cash-cycle log — and the Banco de Portugal's enforcement chain reads the absence of a written entry as a breach of the documentation duty under the cash-cycle compliance regime.
Why CGD Is Litigating an Off-Cycle €9,000 Penalty
For a bank the size of Caixa Geral de Depósitos — €100+ billion in total assets and the largest credit institution operating in Portugal — a €9,000 administrative fine is a rounding-error line item. The bank is litigating for two reasons that have nothing to do with the cash value of the coima.
- Procedural-precedent risk. If the Banco de Portugal interpretation of the documentation duty stands, every counterfeit-detection event across the 480-branch CGD footprint becomes a documented-or-coima exposure. The cumulative enforcement exposure, properly extrapolated, sits in the seven-figure range.
- Supervisory-relationship signalling. CGD is the only public-capital bank in the Portuguese credit-institution stack. The Tribunal de Concorrência, Regulação e Supervisão appeal is a formal signalling channel inside the supervisory relationship — the management is on record that the bank will not pay administrative fines it considers procedurally weak, irrespective of the cash value.
The Tribunal de Santarém Track Record
The Tribunal de Concorrência, Regulação e Supervisão has heard banking enforcement disputes totalling more than €225 million in cumulative penalties over the past decade — the Bank Espírito Santo-cycle, the Banco BPI mortgage-spread litigation, and the ongoing Novo Banco Lone Star portfolio appeals are all on its docket. A €9,000 case is the smallest financial-services dispute in its active queue, and the case will be decided on the legal interpretation of the documentation duty rather than on the cash value of the fine.
What This Means for the Broader Credit-Institution Stack
- Documentation-duty precedent. If CGD wins, the Banco de Portugal will have to redraft the cash-cycle inspection methodology and the documented-validation-step threshold. If CGD loses, the rest of the credit-institution stack — Millennium BCP, Santander Totta, Novo Banco, BPI — will have to refresh their counter-team training and cash-cycle log discipline.
- Public-capital signalling. The Treasury is both the shareholder of CGD and the entity that benefits from the €1.25 billion dividend. The bank's willingness to litigate a state-supervised peer-supervisor signals that the new Paulo Macedo-and-Conselho de Administração layer is consciously resetting the supervisory relationship.
- Timing. The Tribunal de Concorrência, Regulação e Supervisão typically clears administrative-fine appeals in 18 to 36 months. A decision on the €9,000 dispute is plausible inside 2027.
Banco de Portugal had not commented publicly on the appeal as of Monday's reporting cycle.
