Minsky’s concept, developed nearly a half century ago shortly after the explosive decoupling of the dollar from gold in 1971, was primarily a cyclically contained model that acknowledged recession and then rejuvenation once the system’s leverage had been reduced. That was then. He perhaps could not have imagined the hyperbolic, as opposed to linear, secular rise in U.S. credit creation that has occurred since as shown in Chart 1. (Patterns for other developed economies are similar.) While there has been cyclical delevering, it has always been mild – even during the Volcker era of 1979-81. When Minsky formulated his theory in the early 70s, credit outstanding in the U.S. totaled $3 trillion. Today, at $56 trillion and counting, it is a monster that requires perpetually increasing amounts of fuel, a supernova star that expands and expands, yet, in the process begins to consume itself. Each additional dollar of credit seems to create less and less heat. In the 1980s, it took $4 of new credit to generate $1 of real GDP. Over the last decade, it has taken $10, and since 2006, $20 to produce the same result. Minsky’s Ponzi finance at the 2013 stage goes more and more to creditors and market speculators and less and less to the real economy. This “Credit New Normal” is entropic much like the physical universe and the “heat” or real growth that new credit now generates becomes less and less each year: 2% real growth now instead of an historical 3.5% over the past 50 years; likely even less as the future unfolds.
Not only is more and more anemic credit created by lenders as its “sixteen tons” becomes “thirty-two,” then “sixty-four,” but in the process, today’s near zero bound interest rates cripple savers and business models previously constructed on the basis of positive real yields and wider margins for loans. Net interest margins at banks compress; liabilities at insurance companies threaten their levered equity; and underfunded pension plans require greater contributions from their corporate funders unless regulatory agencies intervene. What has followed has been a gradual erosion of real growth as layoffs, bank branch closings and business consolidations create less of a need for labor and physical plant expansion. In effect, the initial magic of credit creation turns less magical, in some cases even destructive and begins to consume credit markets at the margin as well as portions of the real economy it has created. For readers demanding a more model-driven, historical example of the negative impact of zero based interest rates, they have only to witness the modern day example of Japan. With interest rates close to zero for the last decade or more, a sharply declining rate of investment in productive plants and equipment, shown in Chart 2, is the best evidence. A Japanese credit market supernova, exploding and then contracting onto itself. Money and credit may be losing heat and running out of time in other developed economies as well, including the U.S.
