Biography

Jerome Kerviel, born on January 11, 1977, in Pont-l'Abbé, France, is a former trader whose career took a dramatic turn due to one of the largest trading scandals in modern financial history. He joined Société Générale in 2000, starting in the compliance department before moving to a junior trading position. Kerviel was eventually promoted to a trader role in the bank’s Delta One Products team, a department focused on arbitrage trading and index futures. In early 2008, Société Générale revealed that Kerviel had engaged in unauthorized trading activities, leading to staggering losses estimated at €4.9 billion. Kerviel's actions were conducted under a complex system of concealed trades, which he later claimed was partly due to a highly pressurized banking environment. Convicted of fraud, breach of trust, and forgery in 2010, he was sentenced to prison and ordered to repay the full amount, though the fine was later overturned due to its impracticality. Since then, Kerviel has publicly criticized the banking industry, positioning himself as a whistleblower against unethical practices. His story has remained a cautionary tale about risk control in finance, and he continues to attract public attention in France for his outspoken stance on banking ethics.

Useful insights

Hedge Fund Managers Who Broke the Rules

Hedge funds operate in a high-stakes world, where performance is everything. But in several high-profile cases, that pressure led seasoned professionals to break the law. These scandals shook investor confidence and led to major legal and regulatory reforms.

Raj Rajaratnam (Galleon Group)

At its peak, Galleon managed over $7 billion in assets. Rajaratnam built his strategy around exclusive access to confidential information. Prosecutors uncovered a vast insider trading network involving tech executives and consultants, with illegal profits estimated at $63 million. His 2011 conviction, secured through rare wiretap evidence, became a turning point in white-collar prosecution.
Steven A. Cohen (SAC Capital)

Although Steven Cohen himself wasn’t criminally charged, eight of his employees were convicted for insider trading. SAC Capital was accused of fostering a “compliance-blind” culture where information leaks were tolerated. The fund paid $1.8 billion in penalties and was barred from managing external capital. Cohen later returned with a new firm under tighter regulatory constraints.
James Lewis (James D. Lewis & Co.)

Lewis presented himself as a low-risk investment advisor offering fixed returns through bonds and structured notes. In reality, he used new investor money to pay off existing clients, in classic Ponzi fashion. Thousands of mostly elderly investors across the UK were affected. He was sentenced in 2021 after pleading guilty to fraud.

A clear takeaway for me: The illusion of sophistication can be dangerous. Just because a fund is well-dressed and speaks the right language doesn’t mean it plays by the rules. Real professionals value clarity over complexity.
