The U.S. Federal Reserve building in Washington, D.C. Adam Jeffery | CNBC

The Federal Reserve is a government agency that has been entrusted by Congress with two important functions. It sets monetary policy for the nation and it regulates the nation's banks. What is not as clearly understood is that the Federal Reserve is, itself, a bank. It takes in deposits and borrows money. Then, it uses this money to make loans and buy financial securities. Consequently, the Federal Reserve has a balance sheet and an income statement. Each year it produces an annual report on its performance just like any traditional bank would. In 2014, the year before it started to increase interest rates, the Federal Reserve reported that it paid $7.0 billion in interest on the deposits and loans that it had. In that same year, it also reported that it took in $116 billion in interest income derived from the loan and securities that it had invested in. In 2018, it is my estimate, the Federal Reserve paid out $42.8 billion in interest on its deposits and borrowings. At the same time, it is my estimate that it took in $113 billion in interest on the securities and loans that it holds. Let me restate this. From 2014 to estimated 2018, the cost of the money the Fed had acquired jumped by an estimated 511 percent. The yield on the investments that the Fed made had declined by an estimated 2.6 percent. The net result is that in 2014, the Federal Reserve reported a profit of $101.3 billion. In 2018, it is my estimate that the Fed's profit was $63.2 billion; a decline of 37.6 percent. Since the Fed pays virtually all of its profits to the U.S. Treasury, its 2014 payment of $96.9 billion likely declined to an estimated $65 billion in 2018; a decline of 32.9 percent. The taxpayer loses approximately $32 billion because the Fed has seen its interest payments increase and its expected interest income decrease.

How can this happen?

All traditional banks in the U.S. have what are called Asset/Liability Committees or ALCOs. The function of these committees is to protect the stability of bank balance sheets and to monitor the developments in financial markets to insure the profitability of the bank. The numbers above indicate that either the Federal Reserve has no ALCO or the one that it has is simply not competent. A review of the Fed's balance sheet over the years makes it very clear what happened. For virtually all of its history the Federal Reserve obtained the money it needed to operate its bank by printing it. In 2002, for example, when the Fed started publishing its bi-weekly balance sheet, 91.4 percent of the money it needed came from printing currency. The interest cost on this money was and is zero. Therefore, it really did not matter how the Fed invested this money (as long as it did not just give it away) because it would always have a positive spread. In the financial crisis this changed. The Fed kept printing money but it needed trillions more to support its quantitative easing programs which were put in place to stimulate economic growth. If it had simply printed over $2.6 trillion this would have likely have set off an uncontrolled inflation. So it utilized a better technique, it borrowed the money it needed from the banks, which would have no impact on inflation. By the early 2014, it had borrowed so much money from the banks that banks were funding 63 percent of the Federal Reserve's assets and currency was providing 29 percent (capital and others provided the Fed with the remaining 8 percent). To induce the banks to lend them the money, the Fed provided an interest return on Fed Funds and it changed banking rules. It required banks to maintain a certain level of liquidity which could only be achieved by either buying Treasurys or putting money on deposit – i.e., lending money to the Fed. The result of this change was that the Fed went from paying nothing for its funding to paying tens of billions of dollars.
