Overview
MF Global was a global financial-services company specializing in exchange-traded and over-the-counter derivatives. Its activities included futures and options brokerage, contracts for difference, foreign exchange, spread betting and related clearing and execution services. Through MF Global Inc., its U.S. broker-dealer subsidiary, the group also operated as a primary dealer in U.S. Treasury securities. The company represented the brokerage business developed within the historic commodities firm ED&F Man. That business expanded from physical commodities into futures brokerage during the late twentieth century, adopted the Man Financial name, and grew through acquisitions in North America, Europe, Australia and other markets. Important transactions included the purchase of GNI in 2002, which strengthened its contracts-for-difference business and electronic trading capabilities, and the acquisition of client accounts and assets from the failed Refco group in 2005. These deals broadened its retail, institutional and professional customer base. In 2007, Man Group separated its investment-management and brokerage operations. The brokerage business was floated as an independent company and renamed MF Global. The new company sought to compete as a large, internationally integrated intermediary rather than simply as a traditional futures commission merchant. Its business model depended on financing, collateral management, repo transactions, market-making and the efficient movement of client and firm assets across jurisdictions. MF Global encountered growing pressure before its final collapse. In 2008, an unauthorized trading incident generated a substantial bad-debt provision and regulatory penalties, while market concerns about liquidity contributed to a sharp fall in its share price. Jon Corzine, a former Goldman Sachs chief executive and former New Jersey governor and U.S. senator, became chief executive in 2010. Under his leadership, the company pursued a more aggressive balance-sheet strategy and accumulated a large position in bonds issued by heavily indebted European governments. The positions were financed in part through repurchase agreements, including structures that attracted criticism because of their complexity and treatment outside conventional balance-sheet presentation. The strategy became untenable in 2011 as the European sovereign-debt crisis intensified. MF Global reported a large quarterly loss in October, its credit ratings were cut to below-investment-grade status, counterparties and customers became increasingly concerned, and potential rescue transactions failed to prevent a run on liquidity. On October 31, 2011, the company filed for Chapter 11 protection in the United States. Customer accounts were frozen after regulators and exchanges identified a material shortfall in segregated customer funds. Investigations and liquidation proceedings concluded that hundreds of millions of dollars had been transferred from customer-related accounts to meet obligations of the firm or its affiliates. The trustee later estimated customer losses at as much as $1.6 billion. The collapse was one of the largest failures of a Wall Street firm since Lehman Brothers and became a major test of the protections governing futures customers, collateral segregation, rehypothecation and cross-border insolvency. MF Global's U.K. operations entered separate administration proceedings, while the U.S. estate was liquidated. Customer distributions proceeded over several years. A 2013 settlement framework was expected to return approximately 93 percent of customer investments, and later distributions ultimately brought recoveries close to or at full recovery for many customer classes. In 2014, MF Global Holdings agreed to pay $1.2 billion in restitution and a $100 million civil penalty to resolve a U.S. government action concerning customer losses associated with the collapse. The MF Global brand no longer operates as an independent financial institution.
History
MF Global's roots lay in the British commodities business established by James Man in 1783. The enterprise, later known as ED&F Man, gradually expanded from physical commodity trading into financial markets. During the late 1970s and early 1980s it developed a futures-brokerage operation, including Anderson Man, and subsequently used the Man Financial name for the growing brokerage business. Man Financial expanded internationally through acquisitions. The purchase of GNP Commodities in 1989 strengthened its Chicago presence. Later transactions brought in businesses and capabilities associated with Geldermann, Tullett & Tokyo Futures, First American Discount Corporation, Australia's Ord Minnett and other firms. The acquisition of GNI in 2002 was particularly significant because it added a contracts-for-difference franchise and the GNI Touch electronic trading platform. In 2005, Man Financial acquired client assets and accounts from businesses of Refco after Refco's collapse. The transaction, valued at $323 million, materially increased its retail and institutional scale. In 2007, Man Group separated its investment-management operations from its brokerage business. Man Financial became an independently listed company through the separation and initial public offering, adopting the MF Global name. The brokerage group was registered in Bermuda and later moved its registration and headquarters to the United States. Its operations covered futures, options, OTC derivatives, foreign exchange, contracts for difference and spread betting, while its U.S. broker-dealer subsidiary served as a primary dealer in Treasury securities. The company faced governance and risk-control problems before the final crisis. In February 2008, an unauthorized wheat-futures trade led to a $141.5 million bad-debt provision. The CFTC imposed a $10 million fine in connection with that incident and an earlier natural-gas matter, and CME imposed an additional penalty. Shares fell sharply in March amid liquidity concerns, although exchanges and regulators stated that the firm met applicable financial and regulatory requirements at that point. Jon Corzine became chief executive in March 2010. During 2011, MF Global built a position of roughly $6.3 billion in bonds issued by European countries affected by the sovereign-debt crisis. The firm financed and leveraged these positions through numerous repurchase agreements, some of which were complex and treated off balance sheet. As market confidence deteriorated, the positions became difficult to fund and counterparties demanded additional liquidity. MF Global reported a quarterly loss of approximately $191.6 million in October 2011, and Moody's and Fitch downgraded the company to junk status. A sale or rescue could not be completed. On October 30, regulators were informed of a material shortfall in segregated customer funds, and customer accounts were frozen. On October 31, MF Global filed for Chapter 11 protection. The U.S. trustee and related administrators investigated transfers between customer accounts, the broker-dealer and the U.K. subsidiary. Reports described more than $891 million in improper or unexplained transfers, while the trustee estimated the total customer shortfall could reach $1.6 billion. The failure exposed weaknesses involving collateral segregation, rehypothecation, repo financing, off-balance-sheet structures and cross-border supervision. The U.S. estate and the U.K. business were liquidated. Distributions to customers continued through settlement and liquidation proceedings. A 2013 settlement was expected to return 93 percent of customer investments, with additional recoveries possible, and subsequent distributions brought many customers to full recovery. In 2014, MF Global Holdings settled a U.S. government lawsuit by agreeing to restitution of $1.2 billion and a $100 million fine. The company ceased operating, leaving MF Global as a case study in leveraged financial intermediation and the risks of inadequate liquidity controls.
