Bear Stearns
Bear Stearns Companies, Inc. was a New York City-based global investment bank, securities trading, and brokerage firm founded on May 1, 1923, by Joseph Ainslie Bear, Robert B. Stearns, and Harold C. Mayer as an equity trading house with $500,000 in capital.[1][2] The firm grew into one of Wall Street's major players, engaging in investment banking, trading of equities, fixed income, and derivatives, and managing hedge funds, while surviving events like the Great Depression and maintaining a reputation for aggressive trading and high leverage ratios exceeding 30:1.[3][2] Its defining collapse occurred in March 2008 amid the subprime mortgage crisis, precipitated by the failure of two Bear Stearns-managed hedge funds in mid-2007 due to losses on mortgage-backed securities and collateralized debt obligations, which eroded investor confidence and depleted liquidity.[3][2] By March 13, 2008, Bear Stearns faced imminent default, prompting the Federal Reserve Bank of New York to extend emergency liquidity assistance through JPMorgan Chase, culminating in the firm's acquisition by JPMorgan for $10 per share—down from a pre-crisis value of around $170—backed by a $30 billion Federal Reserve facility via Maiden Lane LLC to absorb toxic assets.[3][2] This event marked the first major failure in the 2008 financial crisis, highlighting vulnerabilities from excessive leverage, inadequate risk management, and over-reliance on short-term funding in securitized mortgage markets.[3] The acquisition integrated Bear Stearns' operations into JPMorgan, ending its independent existence and influencing subsequent regulatory reforms like the Dodd-Frank Act.[4]
