Butler had previously been in the role on secondment from the Prudential Regulation Authority (PRA), where she was executive director of International Banks Directorate.
“I am delighted that Megan has decided to stay at the FCA”, said Tracey McDermott, acting chief executive. “She is an extremely experienced regulator with an excellent reputation in wholesale markets and has established herself as a key member of the FCA’s executive team over the past nine months”.
Butler, who is a barrister, joined the Bank of England in April 2013 moving from the Financial Services Authority (FSA). In 2008 she became head of the department responsible for the supervision of the UK operations of the major investment banks.
Prior to that, Butler was head of Enforcement Law and Policy at the FSA and chaired the International Organization of Securities Commissions (IOSCO) Standing Committee on Cross Border Cooperation and Enforcement between 2004 and 2008.
“I am very pleased to take on my role as director of SIWS in a permanent capacity,” said Butler, who joined the FSA in 2000. “There is a huge amount of interesting, challenging and important work to do and I am excited about the opportunity to continue to shape financial services for the better.”
Before the FSA, Butler held a variety of legal and non-legal roles at the London Stock Exchange, including head of capital markets.
