Banks must maintain a certain percentage of their deposits in an account at the Fed known as that bank’s “reserve” account.  Because they do not want to overdraw their account, prudent bankers always seek to hold just a little bit extra.  This little bit extra is known as “excess” reserves.  Prior to the recent recession that “little bit extra” added up over all the banks in the banking system, was a little bit less than $2.0 billion. During the recession when liquidity in the banking system dried up, the Fed essentially put the pedal to the metal and started stuffing reserves into the banking system right and left.  Its overriding objective was to get the economy moving again and, indeed, it succeeded.  The economy turned around in June 2009 which was sooner than many economists had anticipated.  But then the Fed had a problem.  Excess reserves in the banking system today were $1.0 trillion (with a T, not a B).  Those reserves represent funds that could be lent out by banks to fuel a spending spree the likes of which we have never before experienced.  They are, in some sense, “ammo” available to the banking system for lending.

Between the collapse of Lehman Brothers in September 2008 and the end of that year, excess reserves rose quickly from $1 billion to $1.0 trillion.

At the end of 2010 the Fed decided that it was unhappy with the unemployment rate at almost 10% and it engaged in a second round of easing which as become known as QE2 (or Quantitative Easing 2).  They decided to purchase another $600 billion of Treasury securities at a pace of $45 billion per month, which quickly boosted excess reserves to $1.5 trillion.  The effort was designed to push long-term interest rates lower, provide additional stimulus to the economy, and  (hopefully) push the unemployment rate sharply lower.

The third step in Fed easing occurred in September 2011.  They decided to sell $600 billion of Treasury bills and short-dated Treasury notes, and buy an equivalent amount of long-dated Treasuries.  By doing this “swap” the Fed did not further inflate its balance sheet.  The object was to push long rates lower and, hopefully, provide further stimulus to the housing market.

The fourth step in the Fed easing process came in September 2012 when the Fed indicated that it was not happy with the 8.1% level of the unemployment rate and wanted it to decline more quickly.  So to jump start the economy, the housing market in particular, it told us that in addition to its purchases of $45 billion per month of U.S. Treasury securities, it also intended to buy $40 billion of mortgage-backed securities every month until such time as the unemployment rate declined to a more acceptable level.  That was in addition to the $45 billion of Treasury securities that it was purchasing every month.  As a result,  excess reserves  climbed from $1.5 trillion to $2.7 trillion.

Thus, at its peak in late 2013 the Fed was purchasing $85 of long-dated securities every month — $45 billion of Treasury notes and bonds and $40 of mortgage backed securities.  The Fed began to slow its pace of purchases by $10 billion at every FOMC meeting during 2014.  It phased out its purchases of securities in October 2014.

The Fed knows that it must shrink its portfolio to a more “normal” size.  It began to gradually shrink its portfolio by allowing maturing securities to mature.  It started out slowly by reducing its portfolio $10 billion per month in the fourth quarter of 2017.  It then reduced it by $20 per month in the first quarter of 2018, $30 per month in the second quarter, $40 billion in the third quarter, and $50 billion in the fourth quarter.

It came up with a game plan on how  to eliminate the huge volume of excess reserves.  It can raise the rate of interest it pays to banks on their reserves account.  In that event, the excess reserves would still be there, but would effectively be neutralized.  Why lend money to you or me at 4% when banks can keep the money in their reserves account at the Fed, risk free at, say, 2.75%.  Indeed, he Fed has raised the rate it pays on excess reserves from 0.0%% to 2.75%.

However, in January 2019 it said that it plans to conclude the reduction in its holdings of securities at the end of September 2019.  That would leave its aggregate security holdings to stabilize at about $3.7 billion which is somewhat higher than required to efficiently implement monetary policy.

If the Fed stops shrinking its portfolio by the end of September, excess reserves in the banking system should stabilize at about $1.3 billion.  Nobody knows for sure if that level of excess reserves is appropriate.  What the Fed does know is that if all those reserves are used, inflation would skyrocket.  Clearly, the Fed can not and will not allow that to happen. The reserves for the most part currently are simply sitting in the equivalent of a checking account at the Federal Reserve.  They are not boosting the money supply, they are not being lent out extensively to consumers or businesses.   They are not in any way inflationary.  Why?  Because  both consumers and firms have been more interested in paying down debt than in adding to it.  For the first five years of the expansion their income has been going up, their outstanding debt has been going down, hence their “debt burden” became far more manageable.  For the past several years this ratio has remained steady at a level well below its average over the past 35 years

Meanwhile, total loan growth remains modest.  In the past year total loans have risen by 4.9% which is still moderate and sustainable.

But the real question is, will all of this work?  The Fed thinks it can pull it off.  But it is important to remember that they have never been in this situation before.  So far, so good.
