Is America’s Economy Entering a New Normal?

The pandemic, and now the war in Ukraine, have altered how America’s economy functions. While economists have spent months waiting for conditions to return to normal, they are beginning to wonder what “normal” will mean.

Some of the changes are noticeable in everyday life: Work from home is more popular, burrito bowls and road trips cost more, and buying a car or a couch made overseas is harder.

But those are all symptoms of broader changes sweeping the economy — ones that could be a big deal for consumers, businesses and policymakers alike if they linger. Consumer demand has been hot for months now, workers are desperately wanted, wages are climbing at a rapid clip, and prices are rising at the fastest pace in four decades as vigorous buying clashes with roiled supply chains. Interest rates are expected to rise higher than they ever did in the 2010s as the Federal Reserve tries to rein in inflation.

History is full of big moments that have changed America’s economic trajectory: The Great Depression of the 1930s, the Great Inflation of the 1970s and the Great Recession of 2008 are examples. It’s too early to know for sure, but the changes happening today could prove to be the next one.

Economists have spent the past two years expecting many of the pandemic-era trends to prove temporary, but that has not yet been the case.

Forecasters predicted that rapid inflation would fade in 2021, only to have those expectations foiled as it accelerated instead. They thought workers would jump back into the labor market as schools reopened from pandemic shutdowns, but many remain on its sidelines. And they thought consumer spending would taper off as government pandemic relief checks faded into the rearview mirror. Shoppers have kept at it.

Now, Russia’s invasion of Ukraine threatens the global geopolitical order, yet another shock disrupting trade and the economic system.

For Washington policymakers, Wall Street investors and academic economists, the surprises have added up to an economic mystery with potentially far-reaching consequences. The economy had spent decades churning out slow and steady growth clouded by weak demand, interest rates that were chronically flirting with rock bottom and tepid inflation. Some are wondering if, after repeated shocks, that paradigm could change.

“For the last quarter century, we’ve had a perfect storm of disinflationary forces,” Jerome H. Powell, the Fed chair, said in response to a question during a public appearance this week, noting that the old regime had been disrupted by a pandemic, a large spending and monetary policy response and a war that was generating “untold” economic uncertainty. “As we come out the other side of that, the question is: What will be the nature of that economy?” he said.

The Fed began to raise interest rates this month in a bid to cool the economy down and temper high inflation, and Mr. Powell made clear this week that the central bank planned to keep lifting them —…
