How a housing bubble triggered the worst economic downturn since the Great Depression
In short: In the late 1990s, a massive housing bubble began to form, driven by excessive speculation. What started as cheap credit for homeowners eventually evolved into a global liquidity contraction that threatened to dismantle the entire international financial system, leading to the devastating Great Recession.
The 2007–08 financial crisis originated in the United States following the collapse of the U.S. housing market. This crisis was characterized by a severe contraction of liquidity in global financial markets. This era of extreme volatility jeopardised global financial structures, leading to the collapse or near-collapse of many large investment and commercial banks, mortgage firms, insurers, and savings and loan institutions.
Economists continue to dispute the exact causes of the crisis and the relative importance of various factors. However, many point to the actions of the Federal Reserve. Between May 2000 and December 2001, the Fed reduced the federal funds rate 11 times, dropping it from 6.5 percent to 1.75 percent. Such a substantial drop permitted lenders to offer consumer credit at a reduced prime rate, typically three percentage points higher than the federal funds rate.
This cheap credit encouraged lending to even 'subprime' or high-risk customers. Changes in banking laws starting in the 1980s allowed banks to offer these subprime customers loans with adjustable interest rates or balloon payments—unusually large payments due at the end of a loan period. This combination of speculative housing prices and risky lending structures helped precipitate the Great Recession (2007–09), the most significant economic downturn since the Great Depression (1929–c. 1939).
Ultimately, the crisis transformed the housing market from a perceived stable investment into a volatile bubble. As home prices rose well beyond their intrinsic value due to speculation, the underlying fragility of the mortgage-backed instruments became a systemic risk that the global economy could not absorb.
