Sweden's Financial Supervisory Authority has adopted amendments to four rulebooks and one general guideline to align Swedish market venue, investment services and fund rules with changes made under the European Union Listing Act and related national legislation. The main changes update rules linked to the Prospectus Regulation and the Markets in Financial Instruments Directive, with the amendments entering into force on 5 and 6 June 2026. For market venues, the changes revise the content required in an application to register a segment of a multilateral trading facility as an SME growth market, adjust the language rules for prospectuses and for other documents that may in some cases be used instead of a prospectus, and repeal provisions on official listing. For investment firms, the revised securities rules change the conditions under which investment research received from a third party is not treated as a fee or benefit. Consequential amendments were also made to the rules on securities funds, managers of alternative investment funds and the general guidelines on stock exchange lists of certain holdings of financial instruments.
