Banco de Portugal is preparing to introduce a supervisory fee on financial institutions, a move that would align the country with the majority of European Union banking markets. Governor Álvaro Santos Pereira confirmed that banks have already been notified of the plan, which is currently under detailed study.
Why This Matters
• Portugal is an outlier: Among the few EU countries without supervisory charges on banks, despite maintaining comprehensive regulatory infrastructure.
• Banks will likely pass costs to consumers: Any fee structure would likely eventually be reflected in higher loan rates or service charges for customers.
• Separate from new tax proposals: This regulatory fee differs from the government's ongoing work to replace the unconstitutional "solidarity surcharge" on banks, which was struck down last year.
• Timeline uncertain: No implementation date has been announced, though discussions with the banking sector are already underway.
Europe's Standard Practice, Portugal's Exception
The Banco de Portugal has historically funded its supervisory operations through the national budget rather than direct charges on the institutions it regulates. This places Portugal in a minority category within the eurozone, where most national supervisors and the European Central Bank (ECB) routinely recover oversight costs from banks.
Across Europe, countries including Spain, Italy, and Germany have long maintained national supervisory fees, creating dedicated funding for domestic regulatory functions. The rationale is straightforward: institutions benefiting from regulatory stability should contribute to the costs of maintaining that framework.
What This Means for Portugal's Banking Sector
The introduction of a supervisory levy would mark a structural shift in how Portugal finances financial regulation. Currently, Banco de Portugal's oversight activities—ranging from stress testing and liquidity monitoring to inspections and risk assessments—are funded through general budget resources.
Banco de Portugal officials have indicated any fee structure would be "proportional and equitable," suggesting a tiered approach where larger banks with more complex operations would pay more than smaller institutions. The exact financial impact remains unclear pending the study's completion.
Layered on Existing Bank Taxation
The supervisory fee proposal emerges against a backdrop of ongoing debates about bank taxation in Portugal. The sector already pays a "contribution on the banking sector" introduced in 2011 as an extraordinary measure and repeatedly extended.
Separately, Finance Minister Joaquim Miranda Sarmento has been exploring new tax mechanisms since the Constitutional Court's June 2025 ruling that declared the "solidarity surcharge" on banks unconstitutional. The government has committed to presenting a replacement tax proposal during 2026, though no concrete plan has materialized.
Álvaro Santos Pereira emphasized that supervisory fees fall under the central bank's regulatory mandate, while taxation questions remain within government jurisdiction. This distinction suggests the two initiatives will proceed separately.
Timeline and Next Steps
The central bank has not indicated when the study will conclude or when implementation might begin. Banks operating in Portugal currently face regulatory uncertainty on two fronts: the supervisory fee under central bank study and the replacement taxation mechanism under government development.
For residents and customers of Portugal's banking system, any new supervisory fees would likely translate into incremental adjustments to banking costs, though the exact impact depends on how quickly institutions implement changes and how competitive pressures in the market influence pass-through to consumers.
