Overview
Bear Stearns was an American financial-services company established in New York City in 1923 by Joseph Ainslie Bear, Robert B. Stearns, and Harold C. Mayer. It began as an equity-trading partnership and gradually developed into a broad investment-banking, securities-trading, brokerage, and asset-management organization. The company served corporations, institutional investors, governments, broker-dealers, professional traders, and private clients. The firm survived the 1929 Wall Street Crash without dismissing employees and expanded outside New York during the following decades. It opened a Chicago branch in 1933 and an international office in Amsterdam in 1955. During the second half of the twentieth century, Bear Stearns became known for its activity in institutional equities, fixed income, derivatives, foreign exchange, futures, corporate finance, mergers and acquisitions, research, prime brokerage, securities lending, custody, and private-client services. Bear Stearns Securities Corp. also operated global clearing and financing services for broker-dealers and other professional market participants. Bear Stearns was led for much of its modern history by Alan C. Greenberg, who served as chief executive from 1978 to 1993 and remained an influential senior figure afterward. James Cayne succeeded Greenberg as chief executive in 1993. Under Cayne, the company expanded aggressively in structured finance and mortgage-related securities. By the middle of the 2000s, it was one of the largest United States investment banks and was repeatedly recognized in Fortune's securities-firm rankings. At its peak, the company employed more than 15,000 people and maintained offices across the United States, Europe, Asia, and Latin America. The firm's growth was accompanied by substantial leverage and increasing exposure to subprime mortgages and complex collateralized debt obligations. In 2007, two Bear Stearns hedge funds heavily invested in subprime-related securities suffered near-total losses. The episode damaged confidence in the firm's risk controls and revealed how difficult it was to value and finance illiquid structured products. Bear Stearns provided emergency support to one fund and attempted to arrange financing for another, but both funds ultimately failed. The fund collapse was followed by investor claims, regulatory scrutiny, management changes, credit downgrades, and growing concerns about the company's mortgage-related assets. In March 2008, counterparties and lenders rapidly withdrew funding. Bear Stearns' liquidity position deteriorated within days, creating the possibility of a disorderly liquidation that regulators feared could transmit losses through the financial system. On March 14, 2008, the Federal Reserve Bank of New York arranged emergency financing, initially discussed as a short-term loan and then restructured through a special-purpose vehicle later known as Maiden Lane LLC. JPMorgan Chase agreed to acquire Bear Stearns in a government-supported transaction. The original proposal valued the company at approximately $2 per share, but shareholder opposition and contractual issues led to a revised offer of $10 per share. Bear Stearns shareholders approved the sale on May 29, 2008. The acquisition ended Bear Stearns as an independent public company. JPMorgan integrated substantial portions of its operations, including its prime-brokerage, investment-banking, and trading capabilities. In January 2010, JPMorgan discontinued use of the Bear Stearns name. The brand therefore survives primarily as a historical reference to a once-prominent Wall Street institution and to the vulnerabilities created by leverage, illiquid assets, and dependence on short-term market financing.
History
Bear Stearns was founded on May 1, 1923, in New York as an equity-trading house by Joseph Ainslie Bear, Robert B. Stearns, and Harold C. Mayer. The founders contributed capital and built a partnership focused on securities markets. Internal disagreements appeared early, but the firm endured the 1929 Wall Street Crash without laying off employees. Its first branch outside New York opened in Chicago in 1933, and its first international office opened in Amsterdam in 1955. Over subsequent decades, Bear Stearns expanded from a relatively focused trading partnership into a diversified securities firm. It developed activities in investment banking, corporate finance, mergers and acquisitions, institutional equities, fixed-income trading, research, derivatives, foreign exchange, futures, asset management, custody, private-client services, and securities financing. Its clearing subsidiary served broker-dealers, prime-brokerage clients, and other professional traders, including through securities lending. The firm became publicly traded in 1985. Its Manhattan headquarters were eventually located at 383 Madison Avenue, and its network expanded across major American financial centers and international cities. During the 2000s, Bear Stearns was regarded as one of the leading United States investment banks and was recognized in Fortune's corporate reputation surveys. Its business was especially prominent in trading, mortgage finance, structured credit, and prime brokerage. By 2007, it employed more than 15,500 people worldwide. The same expansion created significant vulnerabilities. Bear Stearns maintained a highly leveraged balance sheet and accumulated large positions in mortgage-related securities and other structured-credit instruments. The firm's exposure became difficult to manage as the United States subprime mortgage market deteriorated. Two hedge funds managed by Bear Stearns Asset Management were heavily invested in collateralized debt obligations and related products. In June 2007, the company provided emergency support to one fund and sought financing for another. By July, both funds had lost nearly all of their value. The fund failures led to investor claims, management changes, credit concerns, and questions about whether Bear Stearns had adequately communicated the risks in its portfolios. Former fund managers Matthew Tannin and Ralph R. Cioffi were later prosecuted on charges related to alleged misrepresentation; both were acquitted. Civil and arbitration proceedings by investors and counterparties continued to examine the valuation and disclosure of the funds. In late 2007 and early 2008, the company's mortgage-related losses undermined confidence in its ability to finance itself. Bear Stearns depended heavily on short-term funding and on the willingness of counterparties to accept its collateral. As rumors intensified in March 2008, lenders and trading partners reduced their exposure. The firm's liquidity reportedly fell sharply over a matter of days, creating a self-reinforcing run even though it still held assets that could be offered as collateral. The Federal Reserve Bank of New York intervened on March 14, 2008. The support was restructured through Maiden Lane LLC, a special-purpose company established to acquire a portfolio of Bear Stearns assets. JPMorgan Chase agreed to purchase Bear Stearns in a transaction supported by the Federal Reserve. The original proposal valued the shares at $2 each, but shareholder opposition and a problem in the transaction documentation led to renegotiation. JPMorgan ultimately offered $10 per share, and Bear Stearns shareholders approved the sale on May 29, 2008. The acquisition ended Bear Stearns as an independent company. JPMorgan Chase absorbed its operations and personnel into its broader investment-banking and markets businesses. In January 2010, JPMorgan stopped using the Bear Stearns name. The company's history is therefore closely associated with both the development of modern Wall Street securities markets and the 2007–2008 financial crisis, particularly the risks of leverage, opaque structured products, concentrated mortgage exposure, and reliance on unstable short-term financing.
