The losses followed a strong jobs report that sent US stocks higher in the morning.
The Labour Department said the US economy added 257,000 jobs last month, better than the 235,000 projected by analysts.
The report also included large upward revisions to jobs growth in November and December and said hourly wage growth gained 0.5 per cent, a big improvement after a December drop.
Dow member JPMorgan Chase (+2.0 per cent), Bank of America (+3.3 per cent) and other large banks rose.
A Wells Fargo Advisors note said their gains were due to "rate hike speculation".
Higher interest rates are a net positive for bank earnings.
Bond prices fell. The yield on the 10-year US Treasury rose to 1.95 per cent from 1.81 per cent on Thursday, while the 30-year advanced to 2.53 per cent from 2.42 per cent.
Bond prices and yields move inversely.
