Popular anger, however, reflects a fundamental misunderstanding of the forces driving inflation in the US and beyond. For starters, while the level varies from country to country, today’s inflation is a global phenomenon (bit.ly/2UYMTjs). Annual consumer-price inflation is at 8.2% in the US, 10.1% in the UK, 10.4% in Germany and 11.9% in Italy. Among emerging and developing economies in Asia, year-on-year inflation is at 5.7% in South Korea, 7.4% in India, and 85.5% (not a typo) in Turkey.

While the current outlook for the world economy is undoubtedly grim, we must not lose perspective. Today’s inflationary pressures are nothing like the hyperinflationary episodes of the 20th century. Interestingly, while developing countries in Latin America and Africa have experienced periods of extreme hyperinflation, the worst episodes on record (bit.ly/3WGvKfk) are Hungary’s 1946 bout, followed by Germany’s in 1923. Back then, inflation accelerated so rapidly that the price of restaurant-goers’ lunch would often increase even as they ate what they ordered.

Then as now, soaring prices had profound political consequences. In fact, inflation affects politics more than any other economic indicator. As a recently published report in The Economist (econ.st/3FRHcPc) shows, contrary to popular belief, there is little correlation between economic slowdowns and the popularity of political leaders (I believe the same is true of the unemployment rate).

But, based on my experience as an economist and an advisor to the Indian government, I suspect that a rigorous statistical study would show that inflation disproportionately affects the reputations of political leaders.

This is partly because people do not need data to experience inflation at gut level. The trade balance is just a figure they hear on the news, the latest jobless claims figures do not mean much to them if they have not lost their own jobs, and it takes so long for data on gross domestic product (GDP) to reflect a slowdown that even this indicator may feel abstract. But you do not need to wait for any government data or news reports to learn about inflation. The data on this is available to you every time you go shopping.

It is no wonder, then, that rising inflation is the issue that most concerns US voters. People are often well-informed about inflation and invariably expect the government to be fully in command of it. That makes inflation a key correlate of political (un)popularity. When I was advising the Indian government and annual inflation was hovering close to 10% (bit.ly/3DCFMFo), I remember an elderly uncle phoning me as he was grocery shopping to ask earnestly, “Why are you doing this? Prices have risen again.”

But, contrary to the impression one gets from the confident pronouncements of experts, our understanding of inflationary surges is still rudimentary. We know enough to avoid the mistakes of 1946 and 1923, but beyond that, dramatic price movements remain a confounding challenge for policymakers.

US President Joe Biden’s administration has been criticized for failing to see that the $1.9 trillion American Rescue Plan might lead to price increases (cnb.cx/3zQR5c2). It was obvious to virtually every economist that this enormous covid relief package would cause some inflation, but it is easy to see why US policymakers were wary of acknowledging the risk. High inflation can quickly turn into a self-fulfilling prophecy. A government official who says there will be inflation is almost guaranteed to drive up consumer prices just by saying so.

Many officials within the Biden administration surely could see that the rescue package would cause some inflation, even if they could not say so publicly. But they correctly determined that helping lower-income families withstand the pandemic was worth the risk. And, lest we forget, the main driver of today’s soaring prices, in the US and worldwide, is Russia’s invasion of Ukraine, which severely disrupted global energy supplies.

Although pandemic-relief efforts in the US could have been improved with some minor tweaks, policymakers got it right by risking a moderate increase in inflation to protect the most vulnerable Americans during the worst stage of the crisis. Ignoring this would be short-sighted and morally wrong. But, as Republicans in the US may be about to prove, doing so can be a winning political strategy. ©2022/Project Syndicate
