As of 4 November 2009 the federal reserve reported that the U.S. dollar monetary base is $1,999,897,000,000. This is an increase of 142% in 2 years.

M2, the broadest measure of money supply, has increased from approximately $7.41 trillion to $8.36 trillion from November 2007 to October 2009, the latest month-data available. This is a 2-year increase in U.S. M2 of approximately 12.9%.
