On October 31, 2011, MF Global — the commodities and futures brokerage run by former Goldman Sachs CEO and New Jersey Governor Jon Corzine — filed for bankruptcy. It was the eighth-largest bankruptcy in U.S. history. But the collapse was more than just a failed business: investigators discovered that $1.6 billion in customer funds had vanished. The money that customers had deposited for safekeeping — money that was supposed to be untouchable — had been used by MF Global to cover its own losing bets.
Jon Corzine Takes the Helm
Jon Corzine arrived at MF Global in March 2010 with a glittering resume: CEO of Goldman Sachs, U.S. Senator from New Jersey, Governor of New Jersey. After losing his re-election campaign in 2009, Corzine was looking for a Wall Street comeback. MF Global, a mid-tier commodities broker, seemed like the perfect vehicle.
Corzine had a vision: transform MF Global from a plain-vanilla futures broker into a full-service investment bank in the mold of Goldman Sachs. He wanted proprietary trading, principal investing, and all the high-margin businesses that made Goldman so profitable. The board, dazzled by Corzine’s pedigree, gave him wide latitude to execute this transformation.
The European Debt Bet
Corzine’s strategy centered on a massive bet on European sovereign debt. As the eurozone crisis deepened in 2010 and 2011, the bonds of countries like Italy, Spain, Portugal, and Ireland traded at steep discounts. Corzine believed these bonds would ultimately be made whole — that the European Union would never allow a member state to default — and that buying them at distressed prices represented an enormous opportunity.
MF Global accumulated a $6.3 billion portfolio of European sovereign debt — a position that dwarfed the firm’s capital base. The bet was funded through repurchase agreements (repos) that used the bonds as collateral, creating massive leverage. If the bonds recovered, MF Global would earn enormous profits. If they continued to fall, the firm would face devastating margin calls.
The Margin Call Death Spiral
Through the summer and fall of 2011, the European debt crisis intensified. As bond prices fell, MF Global’s counterparties demanded additional margin — cash collateral to cover the declining value of the European bonds. The firm was hemorrhaging cash to meet these calls while simultaneously seeing its credit rating downgraded by Moody’s, which raised borrowing costs and triggered additional collateral requirements.
In the final week of October, MF Global’s situation became desperate. The firm was burning through cash at an alarming rate. Attempts to find a buyer or additional capital failed. Rating agencies delivered the death blow with further downgrades that triggered automatic margin calls the firm simply couldn’t meet.
The Missing Customer Money
As MF Global spiraled toward bankruptcy, something deeply troubling happened: customer segregated funds — money held in trust for the firm’s commodities and futures clients — were used to meet MF Global’s own obligations. Under federal commodities law, customer funds are sacrosanct. Brokers are legally required to keep customer money separate from their own, and they are strictly prohibited from using it for proprietary purposes.
Yet when the dust settled, approximately $1.6 billion in customer funds was missing. The shortfall affected roughly 38,000 customer accounts, including farmers, ranchers, and small commodity traders who relied on MF Global to safeguard their money. For many of these customers, the missing funds represented their operating capital — money they needed to run their businesses.
The Investigation
The disappearance of customer funds triggered investigations by the Commodity Futures Trading Commission (CFTC), the SEC, and the Department of Justice. The investigations revealed that in the chaotic final days before bankruptcy, MF Global had transferred customer funds to cover its own margin calls and operational expenses.
Corzine testified before Congress that he had never intended for customer funds to be misused and that he had no knowledge of specific transfers. His testimony — punctuated by repeated invocations of “I don’t recall” — drew comparisons to the most notorious corporate testimony in congressional history.
In 2013, the CFTC filed civil charges against Corzine for failing to adequately supervise MF Global’s handling of customer funds. Corzine agreed to pay a $5 million fine without admitting wrongdoing. No criminal charges were ever filed against him — a result that infuriated former MF Global customers who felt that the lack of prosecution reflected a two-tiered justice system.
Customer Recovery
Over the following years, the bankruptcy trustee managed to recover the vast majority of the missing customer funds. By 2014, former U.S. customers had received approximately 100% of their segregated funds, plus interest. The recovery was a significant achievement, but it didn’t undo the years of uncertainty, the disruption to businesses, and the breach of trust that the shortfall represented.
Lessons from MF Global
MF Global demonstrated that the sanctity of customer funds — a bedrock principle of the brokerage industry — could be violated when a firm was in extremis. The case revealed gaps in regulatory oversight: the CFTC and SEC had limited real-time visibility into how brokers managed customer funds, and the existing safeguards proved inadequate under stress.
The scandal also illustrated the dangers of installing a charismatic, risk-taking leader at the helm of a firm with a different culture and risk profile. Corzine’s Goldman Sachs playbook — leveraged proprietary bets funded by cheap financing — was fundamentally incompatible with a commodities brokerage whose primary obligation was the safekeeping of customer assets.
