On August 13, 2015, the UK Payment Systems Regulator published final guidance on its concurrent competition powers and on its approach to market reviews. The PSR has concurrent competition powers with the Competition and Markets Authority. The final guidance on the PSR's powers and procedures under the Competition Act 1998, known as the CA98 Guidance, explains how the PSR will use its concurrent competition powers for participation in payment systems within the UK, in particular the enforcement processes it will follow and how they relate to its other powers and duties. The final guidance on the PSR's powers and procedures for market reviews, market studies and market investigation, known as its Markets Guidance, explains the PSR's powers to carry out market reviews, how the PSR will choose which powers to use, how the PSR will carry out market reviews and studies, including its approach to disclosure and use of information and how the PSR will make market investigation references.
