Instruction No. 1/2026: Regulation of the Credit Responsibilities Register

This Instruction revokes and replaces Instruction No. 17/2018 to incorporate changes from Decree-Law No. 103/2025, which transposed Directive (EU) 2021/2167, establishing a framework for the assignment and management of non-performing bank credits. It expands the scope of participating entities to include credit managers, entities authorized in other Member States, collaborative financing service providers, and potentially other credit institutions, payment institutions, electronic money institutions, and alternative credit investment undertakings. The Instruction introduces the obligation to communicate daily credit events, allows participating entities to access centralized information for the 12 months prior to the latest centralization, and adds requirements for monitoring the debt service-to-income ratio (DSTI) and credit intermediaries. It also exempts participating entities from reporting assignments under Article 9 of the Regime for the Assignment and Management of Bank Credits, as the Banco de Portugal will now receive all such information.

Topics Credit Responsibilities :: Credit Responsibilities Register Mod. 99999940/T – 01/14 Index Text of the Instruction Annex I to the Instruction – Characterization of information blocks, periodicities and communication deadlines Annex II to the Instruction – Description of variables Annex III to the Instruction – Definition of domain tables Annex IV to the Instruction – Information on foreign branches of participating entities Text of the Instruction Subject: Regulation of the Credit Responsibilities Register The main objective of this Instruction is to revoke and replace Instruction No. 17/2018, of August 27, which regulates the functioning of the Credit Responsibilities Register ("CRC"), in order to incorporate the necessary changes for the execution of the provisions of Decree-Law No. 103/2025, of September 11 ("Decree-Law No. 103/2025"), which transposed Directive (EU) 2021/2167 of the European Parliament and of the Council of November 24, 2021, establishing a harmonized framework for access to and exercise of the activity of managing non-performing bank credits, as well as a set of requirements for credit purchasers (Regime for the Assignment and Management of Bank Credits, hereinafter, "RCGCB"), and to revise the CRC regime. Under the terms of the RCGCB, institutions and credit managers are obliged to communicate to the CRC information regarding assigned credits and the information elements related to these credits provided for in the applicable legislation and regulation, namely the information provided within the scope of the CRC. Thus, it is necessary to (i) extend the scope of application to include credit managers as new participating entities, (ii) add additional information for monitoring assigned credits, and (iii) exempt participating entities from the duty to report information on assignments provided for in Article 9 of the RCGCB, given that the Banco de Portugal will, in accordance with the requirements of this Instruction, receive all information provided for in this regard.

Instruction No. 1/2026 Official Gazette No. 2/2026 Supplement • 2026/02/24 Topics Credit Responsibilities :: Credit Responsibilities Register .................................................................................................................................................................................................. Mod. 99999940/T – 01/14 Decree-Law No. 103/2025 also approves a new CRC regime, due to the need to update the existing legislative framework, revoking the previous regime, and notably updating the definition of participating entities, the information subject to centralization, and the scope of centralization communication. In the definition of participating entities, in addition to the entities provided for by way of the RCGCB, their list is extended to incorporate (i) entities authorized in other Member States that grant credit in Portugal under the free provision of services regime, (ii) collaborative financing service providers regarding credits arising from loans they have promoted, and (iii) credit institutions, payment institutions, electronic money institutions, and alternative credit investment undertakings established in another Member State and to which credits originally granted in Portugal have been assigned, may also be designated by the Banco de Portugal as participating entities. Within the scope of information subject to centralization, the obligation to communicate daily credit events is introduced, thus requiring the definition of these events and their respective reporting rules. Within the scope of centralization communication, the possibility for participating entities to access information on centralization relating to the 12 months prior to the last available centralization is introduced. Within the scope of this revision, the following changes are also introduced: (i) incorporation into the text of the Instruction of the reporting requirements applicable to information to be communicated to the Banco de Portugal, (ii) introduction of an additional requirement relating to the ratio between the total amount of monthly installments associated with all loans held by the borrower and their net monthly income after taxes and mandatory social security contributions (debt service-to-income ratio, DSTI), for monitoring the Banco de Portugal's Recommendation regarding new credit agreements concluded with consumers, (iii) introduction of an additional requirement for monitoring credit intermediaries, whose legal regime is established by Decree-Law No. 81-C/2017, of July 7, and (iv) introduction of an additional requirement for evaluating the characteristics of credit products. Thus, as Decree-Law No. 103/2025 revoked the legal regime relating to the CRC, approved by Decree-Law No. 204/2008, of October 14, the revocation of Instruction No. 17/2018 and the adoption of this Instruction is considered more appropriate, in order to ensure greater legal clarity of the regulation. This Instruction was subjected to public consultation, under the terms of Article 101 of the Administrative Procedure Code, approved by Decree-Law No. 4/2015, of January 7, and the National Data Protection Commission was consulted. In these terms, in the exercise of the competence conferred upon it by Article 17 of its Organic Law, approved by Law No. 5/98, of January 31, in its current wording, by Article 2(6), by Article 4(1) and (3), and by Article 6(1), (2), (4) and (5) of the new CRC regime, which is contained in Annex II to Decree-Law No. 103/2025, of September 11, by Regulation (EU) 2016/867 of the European Central Bank, of May 18, concerning the collection of granular credit and credit risk data, and by Article 9(3) and Article 55(a) of the Regime for the Assignment and Management of Bank Credits, which is contained in Annex I to Decree-Law No. 103/2025, of September 11, the Banco de Portugal determines the following: Chapter I General Provisions Article 1 Object The purpose of this Instruction is to regulate the functioning of the Credit Responsibilities Register (CRC), which aims to centralize financial, accounting, and risk information on actual and potential credit responsibilities, arising from credit operations carried out by participating entities, in any form or modality, for which individuals, legal entities, or equivalent, resident or non-resident in national territory, are beneficiaries.
