Stocks Open Lower After Inflation Accelerates

The rapid increase in prices could erode consumer confidencethreatening to unsettle a pillar of the US economy as well as corporate profits.

“Part of the selloff may be that the consumer gets spooked,” said Rich Steinberg, chief market strategist at the Colony Group. “The risk that the markets have is that the consumer backs off further.”

Technology stocks, sensitive to rising interest rates, took an early tumble as the Nasdaq Composite Index lost 1.6%. The Dow Jones Industrial Average retreated 1.1%, about 340 points.

Government bonds sold off, pushing yields higher. The yield on 10-year Treasury notes jumped to 3.043% from 2.958% Tuesday.

The fastest pace of consumer-price growth in four decades has upended financial markets this year by pushing the Federal Reserve to raise interest rates at a rapid clip. The end of the central bank’s pandemic-era stimulus policies has dragged on the stock market, boosted yields on government and corporate bonds and sent the dollar higher. More recently, the Fed’s drive to tighten monetary policy has raised concerns of a looming recession.

“I think the central banks are going to want to see much more than that before they give the all clear,” said Paul O’Connor, head of multiasset at Janus Henderson Investors.

Falling prices for commodities such as oil, grains and industrial metals in recent weeks could be a sign that inflation is starting to ease. Some retailers meanwhile are offering discounts to shed unwanted inventory.

But even if inflation does start to relent, investors expect the Fed to keep raising interest rates and unwinding its bond-purchase program this year. The central bank’s focus, Mr. O’Connor said, is to make sure workers and companies don’t begin to expect inflation to become entrenched—a dynamic that economic theory suggests could become self-reinforcing.

The International Energy Agency said the crisis in oil supplies appears to be easing, pointing to a slowdown in demand and rising output in North America.
