Today alone, Greek bank shares plunged 22-29%, and yield on the 3-year Greek treasury hit 16.97%.

Worst Day in History for Greek Bank Shares

Bloomberg reports Greek Markets Hammered as Fears Grow Over New Government.

 Greek bank shares suffered their worst one day loss on record on Wednesday, as anxiety grew over the new government's plan to renegotiate Greece's €240bn bailout.

The country's four biggest lenders saw their stock prices plummet by an average of more than 25 per cent just two days after Alexis Tsipras, leader of leftwing party Syriza, was sworn in as prime minister. It was the third day of double-digit share slides for the banks.
