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

by Lance Roberts, Streetalk Live

I have spoken, and written, much lately about the fact that the Federal Reserve is beginning to realize that they are caught in a “liquidity trap.” However, what exactly is a “liquidity trap?” The following is one definition:

“A liquidity trap is a situation described in Keynesian economics in which injections of cash into the private banking system by a central bank fail to lower interest rates and hence fail to stimulate economic growth. 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 Reserve’s 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/accommodative 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 that 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 monetary policies.

Lack Of Velocity

The definition of a “liquidity trap” also states that people begin hoarding cash in expectation of deflation, lack of aggregate 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 monetary 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 every time they have tightened 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 accommodative policies did in fact aid in economic stabilization 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 Inflation 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.

  1. Debt Bubble/Crisis temporarily stabilizes an economy in mathematical studies graphs etc, but the phenomenon of apparently rising tranquillity followed by a breakdown still remained mysterious.
    Rob sees cause & effect in theory -V- practice for several reasons:-
    Capital flows to      capitalists as eg. 2012 USA records top 1% gained 11%, National average      was just 2.7% but the majority the 60% poorest sector saw drops in reality      of foreclosures etc. With 11% More to invest the      capitalist yearly satiates more of the available credit demand as      worthiness crashes. They foreclose they cause      property values to crash as supply exceeds demand. They then rent those      assets to former owners at a price well above normal mortgage interest and      they reap a double return in future capital gains as the former owner now      a renter just pores that rent & LOST Gain down the rich drain. As production grows by      machine automation fuel/power cost on the poor worsens, disposable income      dries up they turn to spending borrowings from those same profit makers as      both lender and interest to borrower are lost forever. As domestic demand shrinks      the Producer Capitalist turns to export, their lobbied government to legal      tricks to flood pore Nations the jungle monkeys. But they wake in time and      become competition at cheaper input cost. Once Export & Domestic      demand falls, capitalist lobbies and gets subsidy, stimulus, &      bailouts, culminating in their debt crisis/trap along with the      domestic-consumer/borrower both lacking further credit worthiness and      profitable employment. So where can the money to consume more ever come      from Thus the phenomenon of      apparently rising tranquillity followed by a breakdown is no longer a  mysterious, it is      unprincipled/undereducated politicians lobbied/lulled into short term      fixes that have no viable end cap or repayment ability. The economy      propped up by subsidy and/or war stimulus must eventually return money to      the barter model.  Worker &      Capitalist net Production goes to buyer to more consumer wage to more      buying, but only the state taxes returning as subsidy, stimulus, bailout      demand boosting. Eventually there is no more round money to go round and      Fiat takes over ~ Thus a crash must eventually come to haunt both Capital      and Labor. Professor Kondratiev proved that is in 100 year strict cycles.

  2. “. . . . fail to lower interest rates and hence fail to stimulate economic growth.”
    Two problems:
    1. The Fed has absolute control over the Fed Funds rate, which controls interest rates. 
    2. There is no relationship between low rates and high growth. In fact the opposite is true. Low  rates mean reduced federal spending on interest, which is recessionary.
