Deutsche Bank closed down six percent. UBS lost eight percent.
Investors are concerned about the banks for several reasons.
There is the obvious concern -- that a slowdown in the UK could harm the banks' profits.
Investors are worried that the uncertainty will dent consumer confidence and harm spending.
There is also concern about the prospect of lower interest rates. Lower rates will put pressure on the banks' already squeezed profit margins.
Then there is the worry that if Britain leaves the European Union the UK based banks will lose regulatory protections that allow them to work with clients on the European continent.
It was not just the banks that were sold off.
