As a result of this fraud the group will launch a capital increase of Euro5.5bn over the next few weeks.

France’s second largest bank also said it would post additional write-downs of Euro2.05bn in Q4, Euro1.1bn of which related to US residential mortgage risk.

‘He managed to conceal these positions through a scheme of elaborate fictitious transactions,’ said the bank in a release.

The employee who has admitted to the fraud has been suspended and a dismissal procedure has been initiated.

Julian Spence, senior vice president of Transatlantic Re London, called the incident ‘an extra shock in an already highly stressed environment.’
