Query: How much preferred stock did governments of European nations and the USA purchase in their major banks?
Context: This was the largest liquidity injection into the credit market, and the largest monetary policy action, in world history. Following a model initiated by the United Kingdom bank rescue package, the governments of European nations and the USA guaranteed the debt issued by their banks and raised the capital of their national banking systems, ultimately purchasing $1.5 trillion newly issued preferred stock in their major banks. In October 2010, Nobel laureate Joseph Stiglitz explained how the U.S. Federal Reserve was implementing another monetary policy —creating currency— as a method to combat the liquidity trap.
