Inflation started in the bacon aisle for Dan Burnett, 58, a former medical center administrator who lives in Margaretville, New York.

Last summer, he began to notice that the breakfast staple was increasing sharply in price, jumping to $10 from $8 per pack at his local grocer. Before long, a wide variety of food products were more expensive — so many that he began driving 45 miles to shop at Aldi and Walmart, hoping to score better deals. This summer, it seems that inflation is across the board, pushing up prices on brake repair, hotel rooms and McDonald’s fries.

“My biggest fear is that they don’t get it under control and that it just persists,” Burnett said. He is thinking about how he might have to reshape his financial future in a world where prices — which long had increased at a rate of 2% or less per year — now climb considerably more.

People like Burnett, who is beginning to believe that America’s price burst might last, are the Federal Reserve’s biggest fear. If consumers and companies expect fast inflation to be a permanent feature of the U.S. economy, they might begin to shift their behavior in ways that cause prices to keep rising. Consumers might begin to accept price increases without shopping around, workers might demand higher pay to cover climbing costs and businesses might raise prices both to cover their higher labor bills and because they think customers will stomach the heftier price tags.

Economists often blame that sort of spiraling inflationary mindset for fueling rapid price gains in the 1970s and 1980s, a painful episode in which inflation proved difficult to tame. That is why the Fed, which is responsible for keeping inflation under control, has been focusing on a range of inflation expectation measures, hoping that a high-price psychology is not taking hold.

Most signs suggest that people still believe that inflation will fade with time. But interpreting inflation expectations is more art than science: Economists disagree about which metrics matter, how to measure them and what could make them change. And after more than a year of rapid price increases, central bank officials are increasingly worried that it is foolish to take the stability of price expectations for granted. Officials have been rapidly raising interest rates to try to cool the economy and send a signal to the public that they are serious about wrestling price increases lower.

“There’s a clock running here, where we have inflation running now for more than a year,” Fed Chair Jerome Powell said recently. “It would be bad risk management to just assume those longer-term inflation expectations would remain anchored indefinitely in the face of persistent high inflation. So we’re not doing that.”

Central bankers closely watch measures including the University of Michigan’s longer-term inflation outlook survey as they try to judge whether expectations remain under wraps. Those have moved up since 2020, but have not jumped by as much as actual inflation. Still, those trackers show only where expectations are today. They say little about when they might change or what might shift them.

To get a more detailed, qualitative sense of how consumers are thinking about inflation, The New York Times asked readers what costs were sticking out to them, how much inflation they expected and how they were forming that opinion. The takeaway: Although many people still expect inflation to ease with time, that assumption is a fragile one as many Americans experience the fastest inflation of their adult lives across a broad range of goods and services.

Grocery and gas prices are weighing heavily on many people’s minds, consistent with research about how consumers form price expectations. But the particular products raising eyebrows vary widely and expand beyond just food and gas.

Guitars, rent and pedicures are getting more expensive in California. Artisan crafts are commanding higher prices in New Mexico.

People are coping with the climbing costs in a range of ways.

Many said they were cutting consumption, which could help inflation to ease by lowering demand and giving supply a chance to catch up. A few were continuing to buy, hoping that costs would moderate with time. But others were asking for more pay or trying to find other ways to cover their climbing costs while resigning themselves to increasing prices.

For Siamac Moghaddam, 37, who is in the Navy and lives in San Diego, dealing with inflation has been less about cutting down on little things — like the pedicures he enjoys getting, since he is in boots all the time — and more about saving on big expenses, like rent. His landlord recently raised his apartment rent by $200, so he moved out of his two- bedroom and into a one- bedroom.

“Everyone’s adjusting,” he said. He thinks the Fed’s rate increases will bring inflation under control, though in the process, “I think we’re going to suffer economically.”

Robert Liberty, 68, of Portland, Oregon, is trying to save on food and travel.

“I reached for an avocado in the store, and I jerked back my hand like it was about to be burned when I saw the price — it was $5.50 per avocado,” said Liberty, a part-time lawyer and consultant whose husband works full time. He thinks inflation will moderate, though he is unsure how much. For now, an avocado, he said, is “one thing we can do without.”

Burnett, buyer of bacon, might offer the clearest illustration of why expectations for faster inflation could spell trouble for the Fed if they begin to take hold in earnest. For him, the breadth of today’s price changes makes it hard to believe that inflation will fade soon.

Burnett, who is retired, is thinking about adapting his life accordingly. He co-owns a condominium in Florida with his sister, and maintenance fees on the unit are going up. Though he rents the condo to tenants for only part of the year, he is likely to pass the full increase onto them.

He likes the tenants and does not want to raise rents by so much that he pushes them out, but he also could see himself and his sister charging even more if they notice that neighboring landlords are pushing prices higher.

“I really want to make sure that I’m maximizing income,” he said, given the inflation. And he thinks other people will do the same, which is what makes him think inflation is unlikely to fade soon. “Once people get this mindset of ‘You can increase prices and people will just pay it,’ you’re kind of off to the races.”
