LSE publishes first round of ISM Rulebook amendments for 2025
The London Stock Exchange (LSE) has published Market Notice N06/25, confirming amendments to the International Securities Market (ISM) Rulebook, following its initial consultation (Notice N03/25 from 29 May 2025). These changes, which take effect on 30 June 2025, will clarify existing requirements for expert statements and extend guaranteed bond structure provisions to sukuk instruments (Islamic finance). This consultation marks the first of two planned for 2025, with a second consultation expected to discuss alignment with the Financial Conduct Authority’s new Prospectus Rules. Market participants have responded positively to these technical clarifications. The updated ISM Rulebook will be available on the LSE website from 30 June 2025.
