Big banks are paying big bucks for tech workers, offering more than technology, telecoms or media firms for the in-demand expertise.
IT workers are earning over half as much more at banking and financial services firms and more than twice as much as a contractor.
The daily rate for developers working full time is £300 in banking, compared to just £190 elsewhere. For temporary workers that jumped to £650, and compared with £400 in other lines of business.
"Forget about banks being involved in a tug of war for traders or M&A executives, the IT developer is the new hot property," said Alice Leguay, co-founder and chief operating officer of salary comparison site Emolument, which collected the figures.
"As IT moves from a support function to a key centre of product and business development, banks worry more and more about paying their IT staff - both permanent and contracting - accurately, which is proving a difficult exercise especially with contractors who have wildly fluctuating day rates."
