The question of when did the market crash in 2007 requires a nuanced answer, as the decline was not a single event but a cascading series of failures that eroded confidence over nearly two years. While the peak of the market occurred in October 2007, the unravelelling of the subprime mortgage sector began much earlier, with the most dramatic and publicized collapse occurring in the late summer of 2007. This period marked the end of the credit bubble and the beginning of the liquidity freeze that would eventually trigger the Global Financial Crisis.
The Precursor: The Subprime Mortgage Boom
To understand the crash, one must first look at the fuel that powered the boom. In the years leading up to 2007, financial institutions aggressively issued mortgages to borrowers with poor credit histories. These subprime loans were bundled into complex securities known as Mortgage-Backed Securities (MBS) and Collateralized Debt Obligations (CDOs), which were then sold to investors worldwide. For a time, this system generated massive profits, but it relied on the assumption that housing prices would rise indefinitely and that borrowers would continue to make their payments.
The Initial Shock: February to June 2007
The first signs of trouble emerged in the early months of 2007. In February, New Century Financial, a major subprime lender, filed for bankruptcy protection, signaling that the housing market was faltering. As home prices began to decline, borrowers started to default on their adjustable-rate mortgages, leaving investors holding securities that were suddenly worth pennies on the dollar. By June, the market had begun to price in the losses, but the full scope of the damage was still hidden within the opaque corners of the banking system.
The Critical Moment: August 2007
Bearing Stearns and the Seizure of Liquidity
August 2007 is widely regarded as the official start of the financial market crash. The crisis became impossible to ignore when two Bear Stearns hedge funds, heavily invested in subprime debt, collapsed. This event froze the interbank lending market, as banks became terrified of lending to one another, unsure of who held toxic assets. The cost of borrowing overnight skyrocketed, effectively bringing the global financial system to a halt.
Peak to Trough: The Stock Market Timeline
For the stock market specifically, the peak occurred on October 9, 2007, when the Dow Jones Industrial Average hit 14,164.53. The subsequent decline was brutal and swift. By the end of 2007, the Dow had fallen to 12,987, a loss of roughly 8%, marking the end of the "Great Moderation" and the beginning of a severe bear market that would define the next decade.
