Asset Prices Are Prices Too

We live in inflationary times. Some people might consider this statement controversial. This is because these days inflation is widely understood as a rise in the consumer price index (CPI) of more than 2 percent per year. However, there are convincing reasons to question this viewpoint. On the one hand, the CPI does not include “assets” such as, for instance, stocks, housing, real estate, etc. As a result, the price developments of these goods are not accounted for by the changes in the CPI.

On the other hand, and even more essential, price changes of goods and services are associated with changes in the quantity of money. This is why economists used to understand a rise in the quantity of money as inflationary (and a decline in the quantity of money as deflationary): Without money sloshing around, there could not be a phenomenon like inflation — that is an ongoing upward trend in all prices of goods and services over time. The truth is that rising prices across the board is inextricably linked to money.

Asset Prices Are Prices

One indicator of an inflationary monetary development is the link between the US money stock M2 and nominal GDP. This ratio can be referred to as a measure of “excess liquidity.” Since the outbreak of the crisis 2008/2009, excess liquidity has been growing strongly — as GDP growth lagged behind the increase in the quantity of money. Why? Well, a great deal of the monetary expansion has been driving asset prices upwards — most notably in the stock and housing market.

The Federal Reserve (Fed) has created yet another “inflationary boom.” The US economy is fueled by extremely low-interest rates, accompanied by additional credit and money growth created out of thin air. The monetary expansion leads to an artificial rise in consumption and investment spending, resulting in production and employment gains. Furthermore, the newly created liquidity finds its way into financial (asset) markets, driving up asset prices and even valuation levels.
