Revoked letters

    B3 is currently processing the historical base of Circular Letters, which includes the publication of new Circular Letters consolidating rules or formalizing the revocation of rules that are no longer in effect. In addition, to improve and simplify the way guidelines and rules are disclosed to the market, in the case of a revoked Circular Letter, the revocation information is inserted both in the electronic file (pdf) and in the description field of the letter. To request a copy of Circular Letters published before 2003, which are not in force and not published on the B3 website, please send an e-mail to, indicating the requested Circular Letter..
