NOTE

Decree No. 10.411, of June 30, 2020, provides for the obligation to carry out regulatory impact analysis (AIR) for the issuance of normative acts of general interest produced by the organs and entities of the direct and indirect federal public administration.

However, as defined in paragraph 8 of Vote 280/2021–BCB, of November 10, 2021, the Pix Regulation, including the other documents that integrate, detail, and complement it, do not characterize themselves as a regulatory act of binding and general force, actually possessing, in fact, an eminently contractual nature regarding exclusively the participants of this payment arrangement. Thus, modifications promoted in the aforementioned regulation and in the other documents that integrate, detail, and complement it are not subject to the prior production of AIR.
