UK regulators have sent strong messages to financial institutions operating manipulative trading practices. As at 31 March 2021, the Financial Conduct Authority had 17 market manipulation cases open according to its 2020-21 Annual Report and the Office of Gas and Electricity Markets has also made it clear that market manipulation will not be tolerated. To assist banks’ legal and compliance departments in this area, we have published a new online briefing note, first published on Thomson Reuters Practical Law, explaining: (i) how to recognise manipulative and deceptive trading practices, the different types of market manipulation and key indicators; (ii) how to respond to suspected market manipulation; and (iii) suggested procedures and controls.
