Is the Next Temperamental Era Upon Us?

Excluding the 2007–2009 global financial crisis, the roughly 30-year period that preceded the 2020 pandemic was about as good as it gets for U.S. investors. During that time, which is called the Great Moderation Era, we enjoyed a decrease in the rate of inflation, fewer recessions, and lower economic volatility relative to the prior three decades. At the same time, globalization provided companies with cheap and abundant labor, elevating corporate profits as a percentage of gross domestic product (GDP).

Since the pandemic, however, we've seen an uptick in volatility across many economic and inflation readings, as well as more uncertainty and trade risk on the geopolitical front. We've also seen an increase in labor's power, with wages accounting for a rising share of GDP.

All told, the current environment bears a striking resemblance to the period from the mid-1960s through the early 1990s, which I've dubbed the Temperamental Era. If the comparison holds and we are indeed in a prolonged cycle of macroeconomic choppiness, it could have significant implications for investors.

Here we go . . . again?

If we're to understand the possible sequel, it's important to scrutinize two key characteristics that defined the Temperamental Era:

GDP volatility

The Temperamental Era exhibited more robust growth during periods of economic expansion, but with higher highs and lower lows in GDP growth—and more frequent recessions. Since the pandemic erupted, we've seen similar economic behavior, with the year-over-year change in real GDP swinging from –7.5% in mid-2020 to nearly 12% in mid-2021 to around 5% in 2022.

Big swings

Compared with the subsequent 30 years, the Temperamental Era experienced larger and more frequent swings in real GDP.
