Credit Agricole is the latest to reveal its Greek debt exposure

FRENCH bank Credit Agricole revealed a total £2.17bn corporate exposure to Greece today, as debt worries continued to undermine bank and insurance shares.

Credit Agricole said its insurance unit had slightly less than £347m in exposure to Greek sovereign debt and its interbank risk exposure was £156m.

Credit Agricole shares fell 5.3 per cent in early trading, in line with declines at larger rivals BNP Paribas and Societe Generale.

French banks have the biggest international exposure to Greek debt as at the end of 2009, according to Bank for International Settlements data.

French banks have so far only said they will maintain their exposure.
