Americans are feeling the pinch, and the numbers finally show it.
The August drop ends a period of relative optimism that had lifted the index from its post-conflict low. Even with that gain, the survey shows consumers remain anxious about their purchasing power, and the latest data on retail sales and wages suggests those worries are justified.
The University of Michigan's consumer sentiment gauge fell to 51 in August, down from July's 55.2. That broke a three-month stretch without a decline, and it missed the 55 that economists had expected.
For this report, the University of Michigan gathered survey responses between July 28 and Aug. 10. People surveyed pointed to worsening business conditions and higher prices.
Inflation expectations tell the story. Consumers now expect prices to rise at a 4.3% annual rate over the next year. That is still far above what readings looked like before February, when the Iran conflict started. Over five to 10 years, they expect inflation to run at a 3.3% annual rate.
The gloom was widespread, but it hit some groups harder. Joanne Hsu, who directs the survey, said the drop was sharpest among older consumers, lower-income households, and people without a college degree. She noted those households feel the sting of rising prices more quickly.
"These groups are all particularly vulnerable to any erosion of purchasing power stemming from inflation," Hsu said.
Expectations for the near-term and longer-term economy soured after two months of gains. Inflation worries have grown while unemployment concerns have faded, and the job-market outlook has stayed broadly stable since January.
Friday brought a second piece of bad news alongside the sentiment report. U.S. July retail sales posted their steepest monthly fall in more than a year, following a strong first half of 2026.
Online retailers led the decline. Economists attributed part of that to Amazon.com Inc. moving Prime Day to June this year, which shifted spending into the earlier month.
The bigger issue is what households are working with. Real average hourly earnings in July were 0.2% lower than a year earlier, extending a run of poor data since the Iran war broke out. That squeeze is showing up in how people feel about the economy and how much they are spending.
An economist said, "August's preliminary sentiment reinforces signs of consumer retrenchment. But with inflation expectations elevated, the Fed is caught between softer demand and lingering inflation risks."
The consumer is the engine of the U.S. economy, and this report suggests the engine is sputtering. When sentiment falls and spending slows, companies feel it in their revenue, which eventually shows up in stock prices.
The tricky part is the Fed's position. If consumers are pulling back, that argues for cutting interest rates to encourage spending. But if inflation expectations keep climbing, the Fed has reason to hold rates higher for longer. That tension is exactly what the economist flagged, and it is the backdrop for market moves in the coming months.
The bottom line: When households feel squeezed, it ripples through everything from retail stocks to bond yields. Watching whether inflation expectations keep rising in next month's report will tell you a lot about which way the Fed leans and how much more pain consumers might feel.
