The Dow Jones index dropped 0.86% to 33,127.74 points and the S&P 500 gave up 0.72% to 4,061.22 points. The banking sector led the decline (-1.39%), with some regional banks losing up to half of their stock market valuation.

The big banks also bore the brunt of this turbulence: JPMorgan fell 1.37%, Bank of America -3.09% and Wells Fargo -4.23%. The next step for the market will be, as early as Friday, the release of official US employment figures.
