Early Career

Jerome Kerviel was born on January 11, 1977, in Pont-l’Abbé, France. He graduated from Lumière University Lyon 2 with a degree in finance in 2000. Shortly after, he joined Société Générale, one of the largest financial services groups in Europe, where he began his career in the compliance team before moving to the bank’s Delta One trading desk. This desk specializes in arbitrage and hedging strategies involving equity derivatives.

Unauthorized Trading Activities

The Lead-Up to the Scandal

Between 2006 and 2008, Kerviel carried out a series of unauthorized trades that collectively amounted to positions far exceeding his authorized limits. His tactics included creating fictitious transactions to hide the true nature of his trades, bypassing compliance and risk management controls.

The Scope of Unauthorized Trades

The unauthorized trades primarily involved European stock market futures. Kerviel manipulated the valuation and risk profiles of these positions to delay the bank’s detection. When discovered in January 2008, Société Générale reported losses totaling €4.9 billion ($7.2 billion USD).

Financial Repercussions

The losses incurred from Kerviel’s unauthorized activities forced Société Générale to unwind his positions at significant losses, impacting the bank’s profitability. This incident raised serious concerns about the effectiveness of internal controls and risk management within the financial industry.

In response to this scandal, regulatory bodies and financial institutions around the world re-evaluated their risk management practices. Kerviel was charged with breach of trust, forgery, and unauthorized computer use, leading to his conviction and a five-year prison sentence, with two years suspended. He was also ordered to reimburse the damages, a sum that he has publicly stated he would never be able to repay.
