Investors may be taking the wrong lessons from the 1970s.

It’s hardly a fond memory, but surging prices in the U.S. and other countries this year have investors and pundits banking on a rerun of 1970s-era “stagflation” — a demoralizing combination of stagnant economic growth and high inflation. The comparisons are understandable, but superficial, offering little insight into what’s actually happening below the surface, said Jean Boivin, head of the BlackRock Investment Institute, in a phone interview.

Why understandable? “We haven’t seen an environment where inflation was mostly driven by supply shocks since the 1970s,” said Boivin, a former Bank of Canada deputy governor. But that’s largely where the comparisons end.

Inflation in the 1970s was amplified by oil embargoes that sent energy prices soaring, slowing the economy and feeding inflation. In the current case, the supply shocks are in large part the result of a demand surge tied to the restart of the global economy after the COVID-19 shutdown. That’s an important difference.

Mirror opposites

In fact, the 1970s and the current situation are opposites in important ways, Boivin said. The stagflation of half a century ago came as growth and activity exceeded the global economy’s productive capacity. Now, the economy is running up against supply-chain bottlenecks, which isn’t the same thing. In fact, the economy is still operating below its productive capacity, he said.

That means supply will eventually rise to meet demand, he said, instead of the 1970s experience of demand going down to meet supply.

And while both episodes share soaring oil prices, the story in the 1970s was one in which the oil supply shutdowns by producers slowed the economy and eroded its operating capacity. Energy prices are jumping now because the economy has restarted, “and there’s no way to restart without energy,” Boivin said. “The causality runs the other way.”

‘Inflationary boom’

Other economists have made similar points.

“To be in stagflation, the economy needs by definition to be stagnating, and the evidence for this is quite thin,” said Neil Dutta, head of U.S. economics at Renaissance Macro Research, in an Oct. 18 note. “By all accounts, the economy remains firmly in boom mode.”

To detect signs of stagflation, Dutta used the Institute for Supply Management’s new orders and prices paid indexes.

On one axis, he put new orders, which serve as a proxy for the demand side of the equation, or how much customers are buying. On the other, he put prices paid, a proxy for inflation. (See chart below).

For the economy to be in stagflation, new orders must be below their long-run average — reflecting weak demand from customers — while prices paidrun above its long-run average — meaning inflation is high, Dutta explained. Instead, as shown by the red dots representing 2021 monthly readings, the economy is in an “inflationary boom,” he said, with new orders and prices both strong.

And then theres’ the labor market. Indeed, part of what put the “stag” in the stagflation of the 1970s was the high unemployment that accompanied rising prices.

“At 4.8% today, the unemployment rate is below its 5-, 10-, 15-, 20-, 25-year averages (and so on; you get the picture),” wrote Ross Mayfield, investment strategy analyst at Baird, in a Monday note.

“While the economy is still a few million jobs shy of pre-COVID, the number of job openings is at records and quit rates are soaring,” he said.
