context_page_description: The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. The timing of the Great Depression varied across the world; in most countries, it started in 1929 and lasted until the late 1930s. It was the longest, deepest, and most widespread depression of the 20th century. The Great Depression is commonly used as an example of how intensely the global economy can decline.
  The Great Depression started in the United States after a major fall in stock prices that began around September 4, 1929, and became worldwide news with the stock market crash of October 29, 1929. Between 1929 and 1932, worldwide gross domestic product fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II.
  The Great Depression had devastating effects in both rich and poor countries. Personal income, tax revenue, profits and prices dropped, while international trade fell by more than 50%.
context_section_description: The monetarist explanation was given by American economists Milton Friedman and Anna J. Schwartz. They argued that the Great Depression was caused by the banking crisis that caused one-third of all banks to vanish, a reduction of bank shareholder wealth and more importantly monetary contraction of 35%, which they called "The Great Contraction". This caused a price drop of 33% (deflation). By not lowering interest rates, by not increasing the monetary base and by not injecting liquidity into the banking system to prevent it from crumbling, the Federal Reserve passively watched the transformation of a normal recession into the Great Depression. Friedman and Schwartz argued that the downward turn in the economy, starting with the stock market crash, would merely have been an ordinary recession if the Federal Reserve had taken aggressive action. This view was endorsed by Federal Reserve Governor Ben Bernanke in a speech honoring Friedman and Schwartz with this statement:
  Let me end my talk by abusing slightly my status as an official representative of the Federal Reserve. I would like to say to Milton and Anna: Regarding the Great Depression, you're right. We did it. We're very sorry. But thanks to you, we won't do it again.
   — Ben S. Bernanke
  The Federal Reserve allowed some large public bank failures – particularly that of the New York Bank of United States – which produced panic and widespread runs on local banks, and the Federal Reserve sat idly by while banks collapsed. Friedman and Schwartz argued that, if the Fed had provided emergency lending to these key banks, or simply bought government bonds on the open market to provide liquidity and increase the quantity of money after the key banks fell, all the rest of the banks would not have fallen after the large ones did, and the money supply would not have fallen as far and as fast as it did.
  With significantly less money to go around, businesses could not get new loans and could not even get their old loans renewed, forcing many to stop investing. This interpretation blames the Federal Reserve for inaction, especially the New York branch.
  One reason why the Federal Reserve did not act to limit the decline of the money supply was the gold standard. At that time, the amount of credit the Federal Reserve could issue was limited by the Federal Reserve Act, which required 40% gold backing of Federal Reserve Notes issued. By the late 1920s, the Federal Reserve had almost hit the limit of allowable credit that could be backed by the gold in its possession. This credit was in the form of Federal Reserve demand notes. A "promise of gold" is not as good as "gold in the hand", particularly when they only had enough gold to cover 40% of the Federal Reserve Notes outstanding. During the bank panics, a portion of those demand notes was redeemed for Federal Reserve gold. Since the Federal Reserve had hit its limit on allowable credit, any reduction in gold in its vaults had to be accompanied by a greater reduction in credit. On April 5, 1933, President Roosevelt signed Executive Order 6102 making the private ownership of gold certificates, coins and bullion illegal, reducing the pressure on Federal Reserve gold.
