Sometimes the general public can get confused in attempting to explain the complexities and the inefficiency of the banking sector when one simple chart brings the message home. A chart like that comes from the latest "Eye on the Market" from JPM's Michael Cembalest, who compares total bank deposits ($8.4 trillion), or bank liabilities, and total bank loan (about $2 trillion less) assets, or sources of cash flows that are supposed to fund bank liabilities and generate retained earnings, while the bank performs credit, maturity and risk transformation: a bank's three key functions. As the chart below shows, perhaps the primary reason why the economy is in its current deplorable state, is that instead of lending dollar for dollar to catch up with deposit growth, banks now rely on roughly $1.7 trillion in excess reserves with the Fed, an amount roughly equal to the difference between total deposits and loans, to plug the credibility gap. This also explains why according to Cembalest one of the expectations by the market from Jackson Hole is that IOER will be cut to 0% to promote bank lending, and thus the conversion of reserves into loans (something which the inflationistas out there will tell you is a big risk to a sudden surge in out of control inflation). So how does the Fed's direct intervention in bank balance sheets look like?
