Jerome Kerviel was told he must repay £4.2BILLION after nearly bringing down one of Europe's biggestbanks.
Kerviel, 35, was convicted in a Paris court of forgery, unauthorised computeruse and breach of trustand told to repay the mammoth damages.
He was also jailed for three years - with another two suspended.
But he sought an aquittal and had a two-year fight to clear his name, but the verdict was upheld today.
Kerviel will not go to jail immediately, and his lawyer said that they would study the possibility of a further appeal.
“We had given ourselves the goal of defending Mr Kerviel against an absolutely appalling injustice. I can tell you that we’vefailed,” Kerviel’s lawyer,David Koubbi, told journalists outside the court.
His bosses at banking giant Societe Generale said he carried out huge and risky stock trades worth £45bn without their knowledge between late 2007 and 2008.
The judge in the original case said that the trader’s acts had “damaged the world economic order”.
His former employer said he had lost the £4.2bn they are demanding back through risky trades.
During the trial Kerviel's former boss and colleagues all testified against him.
SocGen's lawyer, Jean Veil, accused Kerviel of"duplicity" for reassuring his bosses that nothing was wrong while racking up the huge losses.
And the bank's president and chief executive at the time, Daniel Bouton, called the trading scandal a"catastrophe".
French media calculated that based on his current salary of £1,700 a month as a computer consultant, itwould take him 177,536 years to pay off the damages.
