U.S. inflation rate heats up to another 40-year high at 7.9%

Propelled by surging costs for gas, food and housing, U.S. consumer inflation jumped 7.9 per cent over the past year, the sharpest spike since 1982 and likely only a harbinger of even higher prices to come.

The increase reported Thursday by the Labour Department reflected the 12 months ending in February and didn't include most of the oil and gas price increases that followed Russia's invasion of Ukraine on Feb. 24.

Since then, average gas prices nationally have jumped about 62 cents US a gallon to $4.32, according to the American Automobile Association (AAA).

Even before the war accelerated price increases, robust consumer spending, solid pay raises and persistent supply shortages had sent U.S. consumer inflation to its highest level in four decades. What's more, housing costs, which make up about a third of the government's consumer price index, have risen sharply, a trend that's unlikely to reverse anytime soon.

For comparison purposes, Canada's inflation rate currently sits at 5.1 per cent, its highest level since 1991. It, too, is expected to go even higher in the coming months.

For most Americans, inflation is running far ahead of the pay raises that many have received in the past year, making it harder for them to afford necessities like food, gas and rent. As a consequence, inflation has become the top political threat to President Joe Biden and congressional Democrats as the midterm elections draw closer. Small business people say in surveys that it's their primary economic concern, too.

Seeking to stem the inflation surge, the Federal Reserve is set to raise interest rates several times this year, beginning with a modest hike next week. The Fed faces a delicate challenge, though: if it tightens credit too aggressively this year, it risks undercutting the economy and possibly triggering a recession.

Energy prices, which soared after Russia's invasion of Ukraine, jumped again this week after Biden said the U.S. would bar oil imports from Russia. Oil prices did retreat Wednesday on reports that the United Arab Emirates will urge fellow OPEC members to boost production. U.S. oil was down 12 per cent to $108.70 US a barrel, though still up sharply from about $90 US before Russia's invasion.

Yet energy markets have been so volatile that it's impossible to know if the decline will stick. If Europe were to join the U.S. and the United Kingdom in barring Russian oil imports, analysts estimate that prices could soar as high as $160 a barrel.

The economic consequences of Russia's war against Ukraine have upended a broad assumption among many economists and at the Fed: that inflation would begin to ease this spring because prices rose so much in March and April of 2021 that comparisons to a year ago would show declines.

Should gas prices remain near their current levels, Eric Winograd, senior economist at asset manager AllianceBernstein, estimates that inflation could reach as high as nine per cent in March or April.

The cost of wheat, corn, cooking oils and metals such as aluminum and nickel have also soared since the invasion. Ukraine and Russia are leading exporters of those commodities.

Even before Russia's invasion, inflation was not only rising sharply but also broadening into additional sectors of the economy. Many prices have jumped over the past year because heavy demand has run into short supplies of items like autos, building materials and household goods.
