When the Federal Reserve buys $50 million in Treasury bills from commercial banks, itsassets increase by $50 million (it now owns $50 million in Treasury bills) but its liabili-ties also increase by $50 million as it credits the banks’ accounts at the Federal Reserve,part of the monetary base. From the perspective of commercial banks, their assets fall by$50 million because they sell Treasury bills to the Fed, but their assets also rise by $50million when their deposits at the Fed (reserves) are credited with $50 million.Initial changes to the T-account of the Federal Reserve immediately after the Fed pur-chase of $50 million in Treasury bills:Initial changes to the T-account of commercial banks immediately after the Fed pur-chase of $50 million in Treasury bills:After the Federal Reserve buys $50 million from commercial banks, the banks areholding $50 million in excess reserves. Since the banks do not want to hold any excessreserves, they will increase loans and deposits by $500 million, the maximum amountthat $50 million in reserves can support. Therefore, the money supply will alsoincrease by $500 million.Total changes to the T-account of commercial banks after the Fed purchase of$50 million in Treasury bills:13.Show the changes to the T-accounts for the Federal Reserve and for commercial bankswhen the Federal Reserve sells $30 million in U.S. Treasury bills.
