This is up from 12 per cent of total salaries last year.
An FSA spokesman says pay increases and bonuses will only be awarded where they are warranted.
He says: “We have put aside up to £10m to support moves to create more effective supervision. There are some staff working here who are being paid less than the accepted level paid in the wider industry. So this money is for salary increases, not bonuses.
“The FSA has also put aside up to 15 per cent of salary for bonuses, but people will only get discretionary bonuses if their performance warrants it. It’s not a guaranteed bonus for everyone.”
The FSA’s Business Plan lists total staff costs, including travel, training and recruitment, as £306.4m for this year, up 24.4 per cent from £246.4 last year.
The regulator has announced it will hire an additional 280 staff for its supervisory enhancement program, taking the total staff at the regulator to just over 3,000.
