In the UK, the Financial Services Authority has recognised and supervises a number of Recognised Investment exchanges (RIEs) under the Financial Services and Markets Act 2000. Recognition confers an exemption from the need to be authorised to carry on regulated activities in the United Kingdom. In order to be recognised, RIEs must comply with the recognition requirements laid down in the Financial Services and Markets Act 2000 (Recognition Requirements for Investment Exchanges and Clearing Houses) Regulations 2001.
