Oil Shock Snuffs Consumer Confidence as Iran War Hits Fragile Recovery

The University of Michigan Consumer Sentiment Index dropped to 55.5 in March 2026—the lowest reading in three months—as households absorbed the economic aftershocks of the U.S.-Israel military campaign against Iran launched February 28. The decline erased gains from interviews conducted before military action began, according to Joanne Hsu, director of surveys at the University of Michigan. The Conference Board Consumer Confidence Index rose just 2.2 points to 91.2 in February, with expectations climbing to 72.0 from 67.2 in January—a tentative stabilization now under siege from a dual shock of surging energy costs and geopolitical volatility.

Brent crude surged from $73 per barrel on February 27 to $107 on March 8—a 46% increase in 10 days—after Iran closed the Strait of Hormuz, through which 20 percent of the world’s oil passes, triggering fuel shortages and rationing in parts of Asia. Prices closed at $103.14 per barrel on Friday, March 13, as the war enters its third week with oil tanker traffic through the strait still at a standstill.

The collision arrives at a perilous moment. U.S. GDP expanded at just 1.4% annualized in Q4 2025, down sharply from 4.4% in Q3, dragged by the longest government shutdown in history. Personal consumption expenditures rose 2.4% in Q4, down from 3.5% in the prior quarter. Forecasters had penciled in a modest 2026 rebound powered by stabilizing sentiment and cooling inflation. EY projects real GDP growth of 2.4% in 2026, with consumer spending expected to moderate amid persistent affordability pressures. The Iran shock rewrites that script.

Gas Prices Deliver Immediate Hit

The average price per gallon of unleaded gasoline climbed to $3.54 on Tuesday, March 10—the highest since mid-2024—marking a 21% increase from a month ago, per AAA. Prices saw their largest three-day jump since Hurricane Katrina in 2005, according to Bespoke Investment Group. Gasoline prices had the most immediate impact on consumers, though the broader pass-through to other prices remains uncertain, with a wide range of respondents across income groups reporting weaker expectations for personal finances, which fell 7.5% nationwide.

The energy channel threatens multiple transmission mechanisms. Average gasoline prices hit $3.50 per gallon as of Monday, their highest level since 2024, up about 57 cents—or 19%—from $2.94 a gallon two weeks earlier. Rising jet fuel costs could filter into higher airfares ahead of spring and summer travel seasons, while more expensive diesel could feed into elevated food prices due to increased costs to transport items to grocery stores, noted CNBC.

Year-ahead inflation expectations ended six months of consecutive declines, stalling at 3.4%—exceeding 2024 readings and remaining well above the 2.3-3.0% range seen in the two years pre-pandemic. Long-run expectations edged down to 3.2%. Interviews completed after February 28 exhibited higher inflation expectations than those completed before that date.

Macro Forecasts in Flux

The sentiment deterioration arrives as Q1 2026 forecasts hinge on consumer resilience. Real consumer spending is projected to slow to 1.6% in 2026, down from an anticipated 2.6% in 2025, per Deloitte—a baseline that assumed no major external shocks. Goldman Sachs analysis predicts Brent crude could average $98 per barrel in March and April, with a sustained 10% increase in oil prices boosting overall inflation by 0.2 percentage points and lowering GDP growth by 0.1 percentage points. Oxford Economics’ worst-case scenario sees oil at $140 per barrel for two months, potentially triggering a mild recession.

The consumer price index rose 2.4% in February from a year earlier, unchanged from 2.4% in January and in line with expectations, though the Federal Reserve aims for 2% using a different but related measure. That precarious equilibrium now faces upward pressure. Resurgent inflation because of energy prices could make the Federal Reserve less likely to cut interest rates; Goldman Sachs changed its forecast for the next Fed rate cut from June to September, and traders began pricing in no rate cuts this year.

Sectoral Divergence Widens

Market reaction has been surgical. The S&P 500 is down 3% from the start of the Iran war—a muted response compared to President Trump’s ‘Liberation Day’ tariff announcement last April, which triggered a 10% weekly decline. On March 12, the S&P 500 fell 1.52% to 6,672.62, the Nasdaq dropped 1.78%, and the Dow shed 1.56%, per The Motley Fool.

ExxonMobil saw earnings outlook transformed, with JPMorgan analysts raising their 2026 EPS estimate to $6.73 from $6.39, while Bank of America set a $151 price target citing projected $52 billion in cash flow for 2025-2026. Chevron is viewed as a ‘conviction buy’ with EBITDA forecasts for 2026 climbing to $44.3 billion, and ConocoPhillips saw consensus revision of full-year EPS to $8.16 after Goldman Sachs added it to its ‘Conviction List.’

Conversely, United Airlines saw its stock drop over 8% on March 9 as investors fretted over the impact of $120 oil on jet fuel expenses, with the airline particularly vulnerable due to heavy exposure to spot fuel prices and long-haul international routes.

Fed Policy Calculus Scrambled

The Federal Reserve held rates at 3.5-3.75% in January after 75 basis points of cuts in late 2025. The FOMC noted that inflation remains somewhat elevated and uncertainty about the economic outlook remains elevated. Governors Waller and Miran dissented from the January decision, arguing for rate cuts, while other members suggested the possibility of rate hikes later in the year should inflation remain elevated.

The Iran conflict injects radical uncertainty into the dual mandate. Oil-driven inflation complicates the disinflationary narrative that would justify further cuts, yet a protracted conflict risking recession strengthens the dovish case. KPMG chief economist Diane Swonk worries the conflict will drag on for up to six months, sending oil prices north of $130 per barrel, with some analysts projecting $200.

What to Watch

The next inflection points cluster in late March. The Conference Board releases its March consumer confidence reading on March 31, capturing the full conflict period. The University of Michigan’s final March sentiment data arrives March 27. February CPI came in at 2.4% year-over-year, but March data—released in mid-April—will reflect the first full month of elevated oil prices.

Strategic reserve releases and diplomatic efforts may cap further oil gains. The IEA coordinated a 400 million barrel release from 32 economies—the biggest-ever emergency stock deployment—yet prices stayed elevated. The U.S. Navy admits it cannot control the Strait of Hormuz, with officials saying military escorts would ‘only be possible once the risk of attack was reduced’—in other words, the strait is too dangerous for the U.S. Navy.

For markets, duration is destiny. The U.S. stock market has a history of bouncing back relatively quickly from Middle East conflicts, as long as oil prices don’t stay too high for too long; the S&P 500 remains just roughly 4% below its all-time high set in January. But what makes this jump frightening is not only the degree—prices jumped near $120 earlier this week—but that they’re occurring during an uncertain time for the economy, raising worries about ‘stagflation’ where growth stagnates while inflation remains high, a miserable mix the Fed has no good tools to fix.

If the conflict extends beyond April, the consumer spending outlook darkens considerably. About 46% of respondents cited high prices as a strain on personal finances, with that share remaining above 40% for seven consecutive months. The recovery from COVID-era disruptions took two years of policy normalization. A prolonged energy shock could compress that timetable—or reverse it entirely.
