From Falling Stocks to Failing Banks
The crash erased billions of dollars of wealth almost instantly. Businesses became uncertain about raising capital, consumers reduced spending, and credit began to contract. The shock did not remain on the stock exchange; it moved through the banking system and into everyday economic life.
Many people blamed commercial banks for placing depositors’ money at risk in the stock market. Others argued that the absence of an effective lender of last resort allowed a normal slowdown after a financial crisis to become much worse.
A Cascade of Closures
In 1930, 1,352 banks holding more than $853 million in deposits failed. In 1931, 2,294 banks failed, involving nearly $1.7 billion in deposits. Businesses also collapsed: 28,285 failures were recorded in 1931, an average of 133 each day.
As banks failed, people and businesses lost access to savings and loans. The resulting uncertainty weakened consumption and investment, while bank closures contributed to a decline in the money supply. The crash therefore became part of a broader cycle of falling demand, business closures, layoffs, and further financial stress.
Reform After the Shock
Congress responded by establishing the Pecora Commission to investigate the causes. The Glass–Steagall Act separated commercial banking from investment banking, dividing deposit-taking and lending from securities underwriting and distribution.
Economists continue to debate whether the crash or the banking collapse played the larger role in the Great Depression. But the sequence makes one point clear: a market crash can be devastating, while a banking crisis can determine how far the devastation spreads.
