I was examining the latest US Federal Reserve Flow of Funds data the other day. This data comes out on a quarterly basis with the latest publication being March 8, 2012. Other related data from the US Treasury (noted below) fills out the picture. The data reveals some interesting trends in terms of US federal government debt issuance over the last 12 months. It shows that the dominant majority of federal debt issued in 2011 was purchased by the US Federal Reserve. Some conservative commentators have expressed horror about this trend. As a proponent of Modern Monetary Theory (MMT) I simply note that the trend demonstrates the nearly infinite capacity of the US government to spend.
