Why is inflation so high, and when will it ease?

Inflation’s relentless surge didn’t merely persist last month. It accelerated.

For the 12 months that ended in June, the government’s consumer price index rocketed 9.1%, the fastest year-over-year jump since 1981.

And that was nothing next to what energy prices did: Fueled by heavy demand and Russia’s invasion of Ukraine, energy costs shot up nearly 42% in the last 12 months, the largest such jump since 1980.

Even if you toss out food and energy prices — which are notoriously volatile and have driven much of the price surge — so-called core inflation soared 5.9% over the last year.

Consumers have endured the pain in everyday routines. Gasoline is up 61% in the last year. Men’s suits, jackets and coats, 25%; airline tickets, 34%; eggs, 33%; and breakfast sausage, 14%.

Under Chair Jerome H. Powell, the Federal Reserve never expected inflation this severe or persistent. Yet after having been merely an afterthought for decades, high inflation reasserted itself with ferocious speed as shortages of labor and supplies ran up against a propulsive rise in demand for goods and services across the economy.

In February 2021, the consumer price index was running just 1.7% above its level a year earlier. From there, it accelerated — past 2% in March, past 4% in April and 5% in May. By December, consumer prices hit the 7% year-over-year barrier. And on and on it went: 7.5% in January, 7.9% in February. And the increases have topped 8% every month since March.

The U.S. has endured worse inflation but not in many decades. Post-World War II inflation peaked at nearly 20% in 1947, a result of the lifting of wartime price curbs, supply shortages and pent-up consumer demand. The inflation of the 1970s and early 1980s peaked at 14.8% in March 1980 before the Fed exorcized high prices with aggressive rate increases that caused brutal, back-to-back recessions in 1980 and 1981-82.

For months, Powell and some others characterized high inflation as merely a “transitory” phenomenon while the economy rebounded from the pandemic recession faster than anyone had expected. No longer. Now, most economists expect inflation to remain painfully elevated well after this year, with demand outstripping supplies in numerous areas of the economy.

So the Fed has radically changed course by imposing a succession of large rate increases. The central bank is making a high-risk bet that it can slow the economy enough to rein in inflation without weakening it so much as to trigger a recession.

The overall economy looks healthy for now, with a robust job market and extremely low unemployment. But many economists warn that the Fed’s steady credit tightening will probably cause a downturn.
