The U.S. stock market was overvalued and positioned to fall before the coronavirus arrived. By the end of 2019, a combination of Federal Reserve policies, stock buybacks and government deficits had elevated stock prices according to virtually all metrics (see chart below).

So how did we get here and where are we going?

In terms of how we got here, the origins of this secular debt cycle originated with the largely ideological decision to deregulate financial markets during the 1980s and 1990s. The two segments of the postwar period provide quite a contrast. During the early postwar period from 1945 until the mid-1970s, credit growth tracked closely with real economic growth, given that most credit was used to support either consumption or the production of goods and services (see chart below).

That dynamic changed from the 1980s until 2007, as financial markets were deregulated and shareholder value (and corporate stock buybacks, permitted under SEC Rule 10b-18) gradually took hold. Wage suppression throughout this time period resulted in middle- and lower-income households borrowing to support consumption, which caused debt levels to begin to rise. How did those households service their debt? It was underwritten by rising house prices and more borrowing. Ultimately, this became a Ponzi scheme that unwound during the global financial crisis (GFC), as real estate values plummeted, as did the net worth of the bottom 90%. As of 2016, the net worth of those households was still more than 30% below 2007 levels.

This set the stage for a very weak recovery, in which annual growth in the real economy has averaged only 2%. And this slow pace of growth was driven in large measure by the sizable debt burden being carried by the bottom 90%. Despite the fact that the Bernanke-led Federal Reserve and the Geithner-U.S. Treasury treated the financial system with kid gloves, handing it a rather nice bailout with few constraints, nothing was done to address the debt levels of many households in the bottom 90%. In other words, these households were largely incapacitated in terms of serving in their historic role as engines for growth in aggregate demand and GDP. (In general, these households have had very high marginal propensities to consume, though not this time).
