FCA has published a new edition of Market Watch, its newsletter on market conduct and transaction reporting. It includes summaries of the recent enforcement action against a US trader for layering and against RBS for transaction reporting failings. The newsletter also highlights how the total amount of suspicious transaction reports (STRs) has doubled since 2011. It also provides updates on LIFFE's switch to ICE Clear Europe as CCP and on Turquoise Derivatives. The latter, a former Multilateral Trading Facility (MTF), will be purchased by the London Stock Exchange and therefore transactions on Turquoise will be subject to rules applying to instruments admitted to trading on regulated markets.
