Municipalities and regional governments that want to borrow in 2026 have new rules of the game. The General Secretariat of the Treasury and International Financing has updated, through the Resolution of April 14, 2026, annex 1 of the Resolution of July 4, 2017 that defines the principle of financial prudence. The reason is clear: the previous parameters no longer reflected real market conditions following the evolution of interest rates in recent years.
Any borrowing operation or derivative that does not comply with these updated limits may be denied by the State, cutting off access to financing for the affected administration.
What does this regulation establish?
The principle of financial prudence is the framework that the State imposes on regional governments and local entities so that their debt operations are considered acceptable. It is not a recommendation: it is a requirement to obtain state authorization that many of these operations legally require.
The April 2026 update modifies annex 1 of the 2017 Resolution to adapt three key elements to current market conditions:
- Maximum interest rates: The upper limits that administrations can pay in their debt operations are updated, reflecting the recent evolution of interest rates.
- Permitted deadlines: The maximum and minimum deadlines allowed for borrowing operations are reviewed.
- Authorized structures: The types of financial structures and derivatives compatible with the principle of financial prudence are defined.
The 2017 regulation established the general framework; the 2026 resolution updates the numerical parameters of that framework so that they remain consistent with the current financial environment. It does not change the architecture of the system, but the specific thresholds within it.
Economic and operational impact
The most direct impact is on the financing capacity of municipalities and regional governments. A credit operation that exceeds the new maximum rates or does not respect the updated deadlines will not be able to obtain state authorization, which in practice amounts to not being able to execute it.
This has cascading consequences:
- Administrations that have ongoing or negotiating operations must verify that their conditions comply with the new parameters before requesting authorization.
- Those planning new debt issuances or loans must design them from the outset within the new limits.
- Financial entities that structure or market debt for these administrations must adapt their proposals so that their public clients can obtain the necessary authorization.
The context is relevant: the update comes after a period of significant interest rate increases in Europe. The 2017 parameters responded to an environment of low or negative rates. Maintaining them without updating would have left out of the principle of financial prudence operations that today are market standard, or would have allowed conditions that are no longer competitive. The update seeks to realign the regulatory framework with the reality of the public debt market.
Who does it affect?
- Regional governments: All those that carry out or plan borrowing operations or derivatives subject to state authorization.
- Local entities (municipalities, provincial councils, island councils): Those that need external financing and must comply with the principle of financial prudence to obtain authorization.
- Financial entities: Banks, savings banks and other entities that structure, market or advise on debt operations for public administrations. Their proposals must fit within the new parameters for the public client to operate.
- Financial advisors and public debt consultants: Those who advise administrations on debt management must know the new limits to design viable operations.
- Comptrollers and financial directors of public administrations: Responsible for validating that operations comply with regulations before requesting authorization from the Treasury.
Practical example
A medium-sized municipality is negotiating with its main bank a long-term loan to finance infrastructure. The operation requires state authorization because it exceeds the thresholds that require this procedure.
The bank proposes conditions that include a fixed interest rate and a specific deadline. Before submitting the authorization request to the Treasury, the municipal comptroller must verify that this interest rate does not exceed the maximum established in the new annex 1 of the 2026 Resolution, and that the proposed deadline is within the permitted range.
If the loan conditions exceed the updated limits, the Treasury may deny authorization. The municipality would have to renegotiate with the bank—seeking a lower rate or a different deadline—or seek an alternative structure that does comply with the principle of financial prudence. Without this adjustment, the operation cannot be legally executed.
This scenario is repeated in any regional government or local entity that operates with external financing subject to state authorization.
What should affected organizations do now?
- Review the new annex 1: Access the full text of the Resolution of April 14, 2026 and extract the updated parameters: maximum rates, deadlines and permitted structures.
- Audit ongoing or negotiating operations: Verify that any borrowing operation or derivative that is in the negotiation process or pending authorization complies with the new limits, not those from 2017.
- Update internal analysis templates: Comptrollers and financial directors of administrations must incorporate the new parameters into their pre-validation tools before submitting authorization requests.
- Communicate changes to counterparty financial entities: Inform the banks you work with that proposals must comply with the new framework to avoid rejections in the authorization phase.
- Plan new operations within the new framework: Any operation designed from now on must be based on the updated 2026 parameters, not the previous ones.
Frequently asked questions
What is the principle of financial prudence for regional governments and municipalities?
It is the set of conditions and limits that borrowing operations and derivatives of regional governments and local entities must comply with to be considered prudent. It includes maximum interest rates, permitted deadlines and authorized structures. It was originally defined by the Resolution of July 4, 2017 of the General Secretariat of the Treasury and Financial Policy.
What changes with the April 2026 update?
The Resolution of April 14, 2026 updates annex 1 of the 2017 Resolution, adapting the reference parameters—maximum interest rates, deadlines and permitted structures—to current market conditions and the recent evolution of interest rates.
If my municipality has a loan in negotiation, do I need to renegotiate it?
Only if its conditions exceed the new limits. If the interest rate, deadline or structure already complies with the updated parameters, no renegotiation is necessary. If it does exceed them, you will need to adjust the conditions before requesting state authorization, as the Treasury will not authorize operations that do not comply with financial prudence.
Who authorizes these operations?
The General Secretariat of the Treasury and International Financing, which is part of the Ministry of Finance. Administrations must request authorization before executing borrowing operations that exceed certain thresholds or involve derivatives.
What happens if an administration ignores these limits?
If an operation that does not comply with the principle of financial prudence is executed without authorization, it can be challenged and declared invalid. Additionally, the administration may face legal and financial consequences, and the operation may be reversed. The practical effect is that non-compliant operations cannot be executed legally.
Do these limits apply to all municipalities and regional governments?
The principle of financial prudence applies to all regional governments and local entities that carry out borrowing operations or derivatives subject to state authorization. Not all operations require authorization—there are thresholds below which authorization is not required—but those that do must comply with these limits.
