Resolution of 6 October 2025 updating Annex 1 on financial prudence principles for autonomous communities and local entities

I. GENERAL PROVISIONS MINISTRY OF ECONOMY, COMMERCE AND ENTERPRISE 20209 Resolution of 6 October 2025, of the Secretary General of the Treasury and International Financing, updating Annex 1 included in the Resolution of 4 July 2017, of the Secretary General of the Treasury and Financial Policy, which defines the principle of financial prudence applicable to debt and derivative operations of autonomous communities and local entities.

The Resolution of 4 July 2017 of the Secretary General of the Treasury and Financial Policy, which defines the principle of financial prudence applicable to debt and derivative operations of autonomous communities and local entities, establishes in its third section that "the total maximum cost of debt operations, including commissions and other expenses, except for the commissions cited in Annex 3, shall not exceed the State's financing cost at the average term of the operation, increased by the corresponding differential as established in Annex 3 of this resolution."

Autonomous Communities and Local Entities that have their own valuation tools or independent external advice may determine the Treasury's financing cost at the time of the operation based on the methodology contained in Annex 2 of this resolution.

The rest of the Administrations, to know the State's financing cost at each average term, will use the table of fixed rates or the maximum differentials applicable to each reference published monthly, by resolution, by the General Directorate of Treasury and Financial Policy. The published maximum costs will remain in force until new costs are published.

In accordance with this obligation to update monthly the State's financing cost at each term, a new Annex 1 is published.

Madrid, 6 October 2025.–The Secretary General of the Treasury and International Financing, Paula Conthe Calvo.

The basis used for the calculation of the maximum annual fixed rate contained in the table above is the Actual/Actual basis. In the event that a different basis is used, the appropriate adjustment must be made.

In fixed-rate operations with an interest accrual period different from one year, the maximum fixed rate must be calculated as the equivalent rate to the annual fixed rate for the considered accrual period.

The maximum fixed interest rates and differentials applicable for operations whose exact average life is not published in this table shall be found by linear interpolation between the two closest rates or differentials to the average term of the operation.

Regarding these fixed interest rates or differentials over EURIBOR, the maximum differentials contained in Annex 3 of the Resolution of 4 July 2017 of the Secretary General of the Treasury and Financial Policy, which defines the principle of financial prudence applicable to debt and derivative operations of autonomous communities and local entities, may be applied.

In the case of debt operations not instrumented in securities with variable interest rates, if the total maximum cost referred to in the third section of the aforementioned resolution is lower than the value of the EURIBOR taken as reference, such operations may be formalized at an interest rate lower than or equal to the reference EURIBOR plus 20 basis points. Debt operations that avail themselves of this alternative must be operations cancellable at any time from their formalization and may not contain cancellation commissions.
