These Regulations add to the list of “relevant enactments” for the purposes of sections 13 to 17 of the Financial Services and Markets Act 2023 (c.29) (“the Act”). Under section 13 of the Act the Treasury may make regulations (an “FMI sandbox”) which may modify the effect or application of such relevant enactments for the purpose of testing the efficiency or effectiveness of new technologies or practices in the carrying on of financial markets infrastructure activities. The effect is to include new relevant enactments within the list at section 17(3) of the Act so that these enactments can be modified by future FMI sandboxes.
