Resolution of 10 August 2026 by the General Secretariat for the Treasury and International Financing updating Annex 1 to the Resolution of 4 July 2017 on financial prudence principles for autonomous communities and local entities

I. GENERAL PROVISIONS
MINISTRY OF ECONOMY, COMMERCE AND ENTERPRISE
17573 Resolution of 10 August 2026, of the General Secretariat for the Treasury and International Financing, updating Annex 1 included in the Resolution of 4 July 2017, of the General Secretariat for the Treasury and Financial Policy, by which the principle of financial prudence applicable to borrowing and derivative operations of autonomous communities and local entities is defined.

The Resolution of 4 July 2017 of the General Secretariat for the Treasury and Financial Policy, by which the principle of financial prudence applicable to borrowing and derivative operations of autonomous communities and local entities is defined, establishes in its third section that "the maximum total cost of borrowing 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 differential corresponding 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 fixed rates table or the maximum differentials applicable to each reference that the General Directorate for the Treasury and Financial Policy publishes monthly, by resolution. The published maximum costs will remain in force until new costs are published.

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

Madrid, 10 August 2026.– The General Secretary for 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 basis other than the aforementioned is used, the appropriate adjustment must be made.

In the case of 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 General Secretariat for the Treasury and Financial Policy, by which the principle of financial prudence applicable to borrowing and derivative operations of autonomous communities and local entities is defined, may be applied.

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