US markets fall as Iran conflict drags consumer confidence to lowest since Dec 2025

U.S. equity markets opened lower on Friday as a fresh wave of risk aversion pushed the Dow down by more than 400 points within an hour, briefly putting the index into correction territory. The move came alongside a University of Michigan survey showing U.S. consumer sentiment fell 6% in March to its weakest level since December 2025. Oil continued its ascent, with Brent crude hitting $110 a gallon, intensifying concerns about inflation and growth. Markets remained jittery despite President Donald Trump’s announcement late Thursday that he would extend a pause on Iranian energy strikes.

Key takeaways

• Within an hour of trading on Friday the Dow dropped over 400 points and briefly entered correction territory (a decline of 10% from a recent peak).
• Consumer sentiment fell 6% in March, the survey’s largest monthly drop to the lowest reading since December 2025.
• Brent crude climbed to $110 a gallon, reinforcing upward pressure on near-term inflation expectations.
• University of Michigan data collection ran from 17 February to 23 March, capturing consumer views across age, income and political groups.
• One-year inflation expectations rose from 3.4% to 3.8%—the largest one-month increase since last April.
• Short-term economic expectations plunged 14%, while longer-term expectations declined more modestly.
• The OECD revised global growth projections downward and warned the Middle East conflict raises global-demand uncertainty.

Background

The current market stress follows an escalation in the Middle East that market participants describe as the US-Israel war on Iran, which has already disrupted trade routes and raised the prospect of sustained energy-supply constraints. Energy infrastructure damage and the risk of halted shipments through choke points such as the Strait of Hormuz have driven oil and commodity price volatility. Policymakers and investors have absorbed several shocks in recent months—trade-policy uncertainty, tighter monetary settings and geopolitical risk—all of which amplify the economic sensitivity to an energy price shock. Historically, sudden spikes in oil prices have fed into inflation expectations, pressured real incomes and prompted central-bank scrutiny.

The University of Michigan Surveys of Consumers has been a bellwether for household sentiment, and the March reading shows broad weakness across demographics, notably among middle-to-upper income households with larger stock wealth. That group’s sharp fall in confidence suggests wealth-channel effects as equity losses and higher energy bills combine to reduce discretionary spending. Central banks and fiscal authorities watch these indicators closely because sustained declines in consumer confidence can feed into weaker consumption and slower GDP growth. At the same time, short-lived sentiment shocks often reverse if the geopolitical episode de‑escalates quickly.

Main event

Trading on Friday turned abruptly risk-off: within the first hour the Dow lost more than 400 points and the selling pressure extended to technology names that had been market leaders. The Nasdaq had already entered correction territory by Thursday’s close after a large one-day drop, defined by an index fall of 10% below its recent peak. Market breadth narrowed as energy and defensive sectors outperformed while cyclicals and growth-oriented names reversed earlier gains.

Oil continued to climb, with Brent crude quoted at $110 a gallon, a level that market participants said is materially higher than recent averages and a direct input to consumer energy bills and producer costs. The price action on energy markets was a primary factor cited by strategists and appeared to be driving rapid recalibration of inflation risk premia embedded in bond and equity markets. Equity volatility indices and commodity-linked FX moves signalled heightened risk-aversion across asset classes.

President Trump announced late on Thursday that he would extend a pause on Iranian energy strikes, a move intended to calm energy markets and quelled some immediate fears of supply disruption. Nevertheless, traders and investors were cautious: many participants said the pause reduces a near-term shock but does not eliminate the underlying geopolitical uncertainty. The result was a mixed response—temporary relief in specific instruments but sustained risk premia elsewhere, particularly in assets sensitive to growth and inflation trajectories.

Analysis & implications

The 6% drop in consumer sentiment in March—across age, political and income groups—signals that households are feeling the economic pain of higher energy prices and stock-wealth erosion. When sentiment weakens among higher-income and wealthier households, the expected decline in discretionary spending can be relatively large because these groups account for a disproportionate share of consumption financed by asset returns. That effect could amplify a growth slowdown even if lower-income consumption remains relatively steady.

Rising one-year inflation expectations, from 3.4% to 3.8%, complicate the policy backdrop for the Federal Reserve. If higher energy costs feed through into persistent inflation, the Fed may face pressure to maintain restrictive policy for longer, which would weigh further on risk assets and borrowing-sensitive sectors. Conversely, if the shock is judged transitory, the Fed may tolerate a temporary uptick in inflation while monitoring growth signals.

Global spillovers matter: the OECD has already trimmed global GDP projections and flagged the conflict as a source of meaningful uncertainty for demand. Emerging markets that are energy importers could see a double hit—higher import bills and weaker external demand—while energy exporters see temporary revenue boosts that may be offset by trade disruptions and insurance-premium spikes. The OECD specifically warned that the UK faces relatively high exposure among industrialized economies due to trade and energy linkages.

Financial markets will be watching two transmission channels closely: (1) the persistence of higher commodity prices into core inflation measures, which would influence long-term interest rates and policy rates, and (2) the effect of falling consumer confidence and equity wealth on consumption and investment, which will influence growth forecasts and corporate earnings. The interplay of these channels will determine whether the current selloff is a short-lived correction or the start of a broader drawdown.

Comparison & data

The table above summarizes the most salient market and survey moves. While the Dow and Nasdaq moves capture market repricing on Friday and Thursday respectively, the consumer survey captures the household-level reaction during 17 February–23 March. Together they show a near-term combination of falling confidence and rising input costs that can compress real spending. Analysts will monitor incoming hard data—payrolls, retail sales and manufacturing indicators—to see whether sentiment is translating into lost activity.

Reactions & quotes

University of Michigan officials contextualised the sentiment shifts as both broad-based and concentrated in wealthier cohorts, suggesting wealth-channel transmission to spending. The survey release included commentary about the interaction of high energy costs and financial-asset valuation effects on household views.

“These patterns suggest that, at this time, consumers may not expect recent negative developments to persist far into the future,”

Joanne Hsu, Director, University of Michigan Surveys of Consumers

Hsu cautioned that views could change if the Iran conflict becomes protracted or if higher energy prices feed through to broader inflation. That caveat highlights the conditional nature of the survey’s signal: sentiment is weak now, but its long-term impact depends on how the geopolitical and price dynamics evolve.

The OECD framed the macroeconomic picture by linking energy-route disruptions to a global-demand shock and higher inflation risks. Officials emphasised the material uncertainty facing national forecasts and the asymmetric impacts across advanced economies.

“The evolving conflict in the Middle East has human and economic costs … and will test the resilience of the global economy,”

OECD report (official)

Markets and policymakers reacted to the OECD’s downward revisions by marking down growth expectations and re-pricing term premia in sovereign and corporate bonds. The OECD also highlighted heightened exposure for the UK among industrialized nations, a point that dominated press and policy discussions in London on Friday.

Unconfirmed

• Whether the pause in Iranian energy strikes will be sustained beyond the near term—current statements do not guarantee a long-lasting de-escalation.
• Whether Brent at $110 a gallon represents a new trading range or a short-lived spike—the durability of this level is still unclear.
• The extent to which higher energy costs will pass through to core inflation measures and force a material change in central-bank policy remains uncertain.

Bottom line

This week’s market moves reflect a classic risk-off response to a combination of geopolitical escalation and rising energy prices: equity indices fell sharply, volatility rose and households reported markedly weaker sentiment. The University of Michigan’s 6% drop in consumer confidence and the rise in one-year inflation expectations to 3.8% are the clearest measured signals that the shock is biting both sentiment and price outlooks.

Policymakers face a trade-off: if the shock is transitory, central banks can look through the inflation impulse; if it proves persistent, monetary policy may need to remain restrictive for longer, increasing the risk of slower growth. For investors and consumers, the key near-term watch items are oil-market dynamics, official diplomatic developments around Iran, and incoming hard economic data that will reveal whether sentiment shifts are translating into weaker spending.
