In the four quarters ended Q1:2019, the chain-price index for personal consumption expenditures increased 1.4%, down from 1.9% in the four quarters ended Q4:2018. This was the slowest increase since 1.0% in the four quarters ended Q3:2016. How can it be that consumer price inflation remains so tame in the face of extraordinarily low unemployment rates and increasing growth in employee compensation (see Chart 1)? The answer could be related to what I like to call Ancient Monetary Theory (AMT). AMT states that goods/price inflation is always and everywhere a function of monetary aggregate quantities. That is, “money” is the root of all sustained goods/services price inflation.
Now, let us examine the relationship between the year-over-year percent changes in the chain-price index for personal consumption expenditures and the year-over-year percent changes in a monetary variable this ancient monetary theorist calls thin-air credit. Thin-air credit is the sum of credit created by depository institutions (primarily commercial banks, saving banks and credit unions) and the monetary base. The monetary base is composed of deposits held at the Federal Reserve owed to depository institutions and all currency issued by the Federal Reserve. When the depository institution system creates additional credit, i.e., makes new loans or purchases securities, this credit is created figuratively out of thin air. When the Fed purchases securities, it, too, is creating credit figuratively out of thin air. The Fed's thin-air credit is the “stuff” of the monetary base. The unique characteristic of thin-air credit is that the recipient of it can increase their spending on goods, services and/or assets without necessitating anyone else to cut back on their current spending. The highest correlation between year-over-year percent changes in thin-air credit and the chain-price index for personal consumption expenditures starting in Q1:1955 through Q1:2019 is obtained when the percent changes in thin-air credit are advanced by 9 quarters in relation to percent changes in the price index. The value of this correlation is 0.58 vs. a maximum value of 1.00. This means that percent changes in thin-air credit lead consumer inflation rates. These data are plotted in Chart 2.
There has been a sharp deceleration in total thin-air credit growth starting in 2009. Starting in Q1:1955 through Q4:2008, the median year-over-year percent change in thin-air credit was 8.1%. Starting in Q:1:2009 through Q4:2018, the median year-over-year growth in thin-air credit slowed to 4.0%. (See Chart 3). According to Ancient Monetary Theory, this sharp deceleration in thin-air credit growth would account for the persistence of relatively low consumer price inflation in the post-Great Recession era.
Plotted in Chart 4 are the year-over-year percent changes in total thin-air credit (the blue line) and its separate components, depository institution credit (the red line) and the monetary base (the green bars) from Q1:2010 through Q4:2018. In two periods of intense Fed quantitative easing (QE), 2011 and 2013, the rapid growth in the monetary base that resulted from QE boosted total thin-air credit growth as growth in depository institution credit slowed. In contrast, in 2018, Fed quantitative tightening retarded growth in total thin-air credit, which caused a contraction in the monetary base, as growth in depository institution credit picked up.
Ancient Monetary Theory posits that consumer price inflation is a function of the behavior of monetary aggregate quantities. My research suggests that the behavior of thin-air credit is a relatively good predictor of future consumer price inflation trends. My research also suggests that there is a long lag, over two years, between growth in thin-air credit and the consumer price inflation rate. Thus, how the Fed allows thin-air credit to behave today has an important effect on the consumer price inflation rate two years hence. If the Fed wants to stabilize consumer price inflation, it ought to stabilize the growth of thin-air credit.
