What Is A "Liquidity Trap" And Why Is Bernanke Caught In It?

A liquidity trap is caused when people hoard cash because they expect an adverse event such as deflation, insufficient aggregate demand, or war. Signature characteristics of a liquidity trap are short-term interest rates that are near zero and fluctuations in the monetary base that fail to translate into fluctuations in general price levels." Let's take a moment to analyze that definition by breaking it down into its overriding assumptions.   First, is the Fed pushing cash into the private banking system?  The chart below shows that that answer is "yes".    In September of 2008 the excess reserves of major banks was just $9 billion.  After the Lehman failure excess reserves have now skyrocketed to $2.07 trillion.  That is roughly an increase of $400 billion in excess reserves annually. However, has the increase in liquidity into the private banking system lowered interest rates?  That answer is also "yes."   The chart below shows the increase in the Federal Reserves balance sheet, since they are the "buyer" of bonds which in turn increases the excess reserve accounts of the major banks, as compared to the 10-year treasury rate.  While, in the Fed's defense, it may be clear that since the beginning of the Fed's monetary interventions that interest rates have declined this has not really been the case.  I would venture to argue that, in fact, the Fed's liquidity driven inducements have done little to effect the direction of interest rates.  I say this because interest rates have not been falling just since the monetary interventions began - it is a phenomenon that began three decades ago as the economy began a shift to consumer credit leveraged service society.  The chart below shows the correlation between the decline of GDP, Interest Rates and Inflation. The ongoing decline in economic activity has continued to be the driving force behind falling inflationary pressures and lower interest rates.  It is hard to attribute much of the recent decline in interest rates to monetary/accomodative policies when the long term trend was clearly intact before these programs began.  The real culprits behind the declines in economic growth rates, interest rates and inflation is more directly attributable to increases in productivity, globalization, outsourcing and leverage (debt service erodes economic activity). However, the real question is whether, or not, all of this excess liquidity and artificially low interest rates is spurring economic activity?  To answer that question let's take a look at a 4-panel chart of the most common measures of economic activity - Real GDP, Industrial Production, Employment and Real Consumption. While an argument could be made that the early initial rounds of QE contributed to the bounce in economic activity it is important to also remember several things about that particular period.  First, if you refer to the long term chart of GDP above you will see that economic growth has ALWAYS surged post recessionary weakness.  This is due to the pent up demand the was built up during the recession that is unleashed back into the economy.   Secondly, during 2009 there were multiple bailouts going on from "cash for houses", "cash for clunkers", direct bailouts of the banking system and the economy, etc.  However, the real test for the success of the Fed's interventions actually began in 2010 as the Fed became "the only game in town".   As shown above, at best, we can assume that the increases in liquidity have been responsible in keeping the economy from slipping into a secondary recession.  With most economic indicators showing signs of weakness it is clear that the Federal Reserve is currently experiencing a diminishing rate of return from their montary policies. Lack Of Velocity The definition of a "liquidity trap" also states that people begin hoarding cash in expectation of deflation, lack of aggregrate demand or war.  The 4-panel chart below shows that both individuals, and corporations, have been stock piling cash since the beginning of this century.  As the "tech bubble" eroded confidence in the financial system, followed by a bust in the credit/housing market, cash has become a "sacred cow."   In turn this has pushed monetary velocity to the lowest levels on record as the economy continues to weaken as deflationary pressures persist, the demand for credit remains weak and consumption remains constrained by stagnant wage growth. The issue of montary velocity is the key to the definition of a "liquidity trap."  As stated above: "The signature characteristic of a liquidity trap are short-term interest rates that are near zero and fluctuations in the monetary base that fail to translate into fluctuations in general price levels."  The chart below shows that, in fact, the Fed has actually been trapped for a very long time. The problem for the Fed has been that for the last three decades everytime they have tightend monetary policy it has led to an economic slowdown or worse (as shown by the vertical dashed lines).  The onset of economic weakness then forced the Federal Reserve to once again resort to lowering interest rates to stabilize the economy.  The issue is that with each economic cycle rates continued to decrease to ever lower levels.  In the short term it appeared that such accomodative policies did in fact aid in economic stabilzation as lower interest rates increased the use of leverage.  However, the dark side of those monetary policies was the continued increase in leverage which led to the erosion of economic growth, and increased deflationary pressures, as dollars were diverted from productive investment into debt service.  Today, with interest rates at zero, the Fed has had to resort to more dramatic forms of stimulus hoping to encourage a return of economic growth and controllable inflation.  No Escape From The Trap For the Federal Reserve they are now caught in the same "liquidity trap" that has been the history of Japan for the last three decades.  With an aging demographic, which will continue to strain the financial system, increasing levels of indebtedness and poor fiscal policy to combat the issues restraining economic growth it is unlikely that continued monetary interventions will do anything other than simply foster the next boom/bust cycle in financial assets.   The chart below shows the 1-year Japanese Government Bond yield as compared to their quarterly economic growth rates.  Low interest rates have failed to spur sustainable economic activity over the last 20 years. As I stated recently in "What Inflaton Says About Bonds & The Fed:" "The real concern for investors, and individuals, is the actual economy. We are likely experiencing more than just a 'soft patch' currently despite the mainstream analysts' rhetoric to the contrary. There is clearly something amiss within the economic landscape and the ongoing decline of inflationary pressures longer term is likely telling us just that. The big question for the Fed is how to get themselves out of the 'liquidity trap' they have gotten themselves into without cratering the economy, and the financial markets, in the process. As we said recently this is the same question that Japan is trying to figure out as well." Should we have an expectation that the same monetary policies employed by Japan will have a different outcome in the U.S?  More importantly, this is no longer a domestic question - but rather a global one since every major central bank is now engaged in a coordinated infusion of liquidity.  The problem is that despite the inflation of asset prices, and suppression of interest rates, on a global scale there is scant evidence that the massive infusions are doing anything other that fueling the next asset bubbles in real estate and financial markets.  The Federal Reserve is currently betting on a "one trick pony" which is that by increasing the "wealth effect" it will ultimately lead to a return of consumer confidence and a fostering of economic growth?  Currently, there is little real evidence of success.   Are we in a "liquidity trap?"  Maybe.   Of course, no one recognized Japan's problems either until it was far too late.
