What we see here is that the banks are holding excess reserves in excess of $1.7 trillions, this is not part of the money in circulation and does not effect market prices. However, M2 money supply incresed by $3.2 trillions since the beginning of great recession in December of 2007 and this money definitely does affect prices.
Below is the M3 chart, FED stopped publishing M3 numbers so the chart only shows figures up to 2006.
Below is the Federal Reserve balance sheet dated 2013-08-14. The FED buys assets with the money it creates adding to the money supply in addition to the monetary base. Total asset figure is $3.68 trillions, this money is in circulation.
