Causes of the Great Depression
Second, there are the monetarists, who believe that the Great Depression started as an ordinary recession, but that significant policy mistakes by monetary authorities (especially the Federal Reserve) caused a shrinking of the money supply which greatly exacerbated the economic situation, causing a recession to descend into the Great Depression. Related to this explanation are those who point to debt deflation causing those who borrow to owe ever more in real terms.
Great Depression in the United States
Whether this caused the Great Depression is still heavily debated due to many other attributing factors. However, it is evident that the banking system suffered massive reductions across the country due to the lack of consumer confidence. As withdraw requests would exceed cash availability banks began conducting steed discount sales such as fire sales and short sales. Due to the inability to immediately determine current value worth these fire sales and short sales would result in massive losses when recuperating any possible revenue for outstanding and defaulted loans. This would allow healthy banks to take advantage of the struggling units forcing additional losses resulting in banks not being able to deliver on depositor demands and creating a failing cycle that would become wide spread. Investment would continue to stay low through the next half decade as the private sector would horde savings due to uncertainty of the future. The federal government would run additional policy changes such as the Check tax, monetary restrictions (including reduction of money supply by burning), High Wage Policy, and The New Deal through the Hoover and Roosevelt administration.
