Why Did Société Générale Fail?
One Junior Trader, €50B in Secret Bets
📜 What Happened
Jérôme Kerviel was a junior trader who'd worked in the bank's back office — so he knew exactly which controls checked what, and when. He built €50B in unauthorized positions (more than the bank's entire market value), hiding them with fake offsetting trades timed to vanish before checks ran. Compliance flagged anomalies 74 times; each time his explanations were accepted. When the bank finally found the truth, unwinding the position in a falling market cost €4.9B.
☠️ The Fatal Mistake
74 warnings dismissed because the profits looked good — controls existed on paper but every alarm was explainable away while the numbers went up.
