Dexia shares in new slump as Greece worries continue

Shares in the Franco-Belgian bank Dexia have fallen for a second day on fears over its exposure to Greek debt.

They fell 37% at the open on Tuesday, adding to a 10% Monday drop prompted by an alert by ratings agency Moody's, but rallied back to a mere 21% down.

Former chairman of Citigroup, William Rhodes, said that the share price drop reflects what is happening within the global banking sector.
