Anyone can see the current composition of the Fed's balance at https://www.federalreserve.gov/monetarypolicy/bst_fedsbalancesheet.htm https://www.federalreserve.gov/monetarypolicy/bst_fedsbalanc... -- the latest balance sheet is here: https://www.federalreserve.gov/releases/h41/current/h41.htm#h41tab1 https://www.federalreserve.gov/releases/h41/current/h41.htm#... As anyone can easily confirm, US treasury bonds and agency-backed bonds constitute the vast majority of the ~$9T owned by the Fed today. During the global financial crisis, I believe the Fed was given permission (by the executive and legislative branches) to purchase other kinds of bonds, so it coulld maintain financial and monetary stability.
