The number of staff who have left the FSA over the past year has almost doubled on the previous year, ahead of the move to the new regulatory structure.
A Freedom of Information request submitted by The Independent has revealed that over the past 12 months 352 employees quit the regulator compared to 181 the year before.
Between April and September last year 187 people left the FSA, more than the number that left over the entire previous year.
The FSA says the number of staff leaving is in line with levels seen before the financial crisis to reflect a pick up in financial services recruitment.
In 2008/09 206 regulator staff quit, compared to 326 employees who left in 2006/07.
FSA human resources director Kathleen Reeves says: “Staff turnover levels fell during the crisis but are now starting to return to the level you would expect as recruitment picks up in the financial services sector.”
The regulator has been hit by a spate of high profile departures over recent months.
Former head of risk Sally Dewar left the regulator in January and will join JP Morgan Chase’s London office in June to work within its risk division.
Former managing director of supervision Jon Pain also left the FSA in January, and will join KPMG as a partner in July as part of a division that collects information on financial services regulatory developments.
Last month also saw the departure of insurance sector director Ken Hogg, who left the regulator to join reinsurer RGA as chief actuary and financial officer for the UK.
It comes ahead of the planned transition to the new regulatory structure, which will see the FSA replaced by two new bodies, the Prudential Regulation Authority and the Financial Conduct Authority.
The restructure is expected to be completed by the end of 2012 or early 2013.
