The Brief

The University of Michigan’s preliminary March consumer sentiment index fell to 55.5 — the lowest reading of 2026 and the second percentile of the survey’s entire history — as the Iran conflict drove gasoline prices up more than 20 percent and erased gains recorded before the war began. Personal finance expectations dropped 7.5 percent across all income levels, age groups, and political affiliations.

The Report

American consumer confidence sank to its weakest point this year in early March, with the University of Michigan’s preliminary sentiment index falling to 55.5 from February’s 56.6. The reading places current sentiment 33.9 percent below the survey’s long-run average of 84.0, deep in the second percentile of data stretching back decades.

The survey’s timing captured the conflict’s impact in real time. Roughly half of the interviews were conducted before the February 28 U.S.-Israeli military action against Iran, and roughly half after. The split told the story cleanly: pre-conflict respondents showed improving sentiment; post-conflict respondents pulled the index down enough to erase those gains entirely. Consumer expectations — the forward-looking component — fell 4.4 percent to 54.1, the weakest since November.

Gasoline is the transmission mechanism. The national average reached $3.63 per gallon by Friday, up from $2.94 a month earlier — a 23.5 percent increase. Crude oil has climbed roughly 42 percent from its pre-war baseline of $67 per barrel to approximately $95, having briefly touched $110. Diesel rose 28 percent to $4.83 per gallon, a figure that feeds directly into freight, agriculture, and food supply costs. Among consumers surveyed after the conflict began, 42.6 percent expected higher gas prices over the coming year, compared with 10.0 percent of those surveyed before it — a 326 percent surge in gas-price anxiety.

Year-ahead inflation expectations stalled at 3.4 percent, ending six months of consecutive declines and sitting well above the pre-pandemic range of 2.3 to 3.0 percent. “Consumers expect their purchasing power to be eroded in the year ahead,” said Joanne Hsu, director of the Michigan surveys.

The sentiment data arrived alongside a downward revision to fourth-quarter GDP, now estimated at 0.7 percent annualised growth — half the initially reported 1.4 percent. Consumer spending decelerated from 3.5 percent in the third quarter to 2.4 percent, with goods purchases turning negative. February nonfarm payrolls fell by approximately 92,000 positions. The Conference Board’s Expectations Index has remained below its recession-signal threshold of 80 for thirteen consecutive months.

Gregory Daco, chief economist at EY-Parthenon, cautioned that monthly inflation could reach as high as 1 percent in March — a four-year peak — if oil prices hold. “The longer this lasts,” Daco said, “the more significant the shock would be.” Goldman Sachs has placed the probability of recession at 25 percent.

The decline in sentiment was notable for its breadth. The highest-income consumer segment — the cohort whose spending sustained aggregate consumption through 2023 and 2024 — registered sharp drops alongside lower-income households. The erosion of that spending cushion, in an economy already losing jobs and revising growth downward, removes a buffer that previous shocks left intact.

The Angle

What makes this reading worth pausing on is less the number itself — 55.5, bad, expected — than the structure underneath it. Sentiment was improving before February 28. The economy was weak but directional. Then a single geopolitical event rerouted the entire psychological trajectory of the American consumer within nine days. The pre-conflict and post-conflict halves of the same survey read like two different countries.

The interesting detail is the high-income collapse. In 2023 and 2024, wealthier households propped up an economy that should have slowed sooner, spending through conditions that squeezed everyone below them. That insulation is now visibly thinning. Gas prices are regressive, but gas-price anxiety is apparently not — it reaches the top of the income distribution with the same force, which suggests the signal consumers are reading is not the price at the pump but what the price at the pump implies about what comes next. The cost of a gallon of fuel is manageable. The cost of a war nobody can predict the duration of is not. What the survey measured was not pain. It was the withdrawal of permission to plan ahead.
