If the Federal Reserve’s chair, Jerome H. Powell, and his colleagues look at company earnings reports, these themes might catch their eye.Federal Reserve officials are battling the fastest inflation in four decades, and as they do they are parsing a wide variety of data sources to see what might happen next. If they check in on how executives are describing their companies’ latest financial results, they might have reasons to worry.It’s not because the corporate chiefs are overly gloomy about their prospects as the Fed aggressively raises interest rates to control rapid inflation. Quite the opposite: Many executives across a range of industries over the last few weeks have said they expect to see sustained demand. In many cases, they plan to continue raising prices in the months ahead.That is good for investors — the S&P 500 index gained 8 percent last month as companies began reporting quarterly profits — but not necessarily welcome news for the Fed, which has been trying hard to slow consumer spending. The central bank has already raised rates five times this year and is expected to do so again on Wednesday as part of its campaign to cool off the economy. Although companies have warned that the economy may slow and often talk about a tough environment, many are not seeing customers crack yet.“While we are seeing signs of economic slowing, consumers and corporates remain healthy,” Jane Fraser, the chief executive of Citigroup, told investors recently. “So it is all a question of what it takes to truly tame persistently high core inflation.”If companies continue to charge more and consumers are still willing to pay, inflation will be harder to stamp out. That could push the Fed to keep up its push to curb momentum — and if officials must do more to wrestle prices down, it could increase the risk of financial turmoil, higher unemployment or other bad outcomes. Although some companies are reporting a nascent slowdown, the signs are far from conclusive.Demand remains strong despite higher prices.McDonald’s expects to raise prices 10 percent at its restaurants in the United States this year, its leaders said when reporting better-than-expected sales and profits for the third quarter.“I think because of the strength of the brand and the proposition as evidenced by the results, the consumers are willing to tolerate it,” said Chris Kempczinski, the fast-food giant’s chief executive.Inflation F.A.Q.Card 1 of 5What is inflation?
