US Consumer Defies Record Gloom, Spending Over 8% More as Iran War Roils Global Markets

American consumers have never felt worse, yet they continue to spend, creating a tense standoff between sentiment and reality that now underpins the global economy.

The U.S. economy is caught in a striking paradox where consumer spending remains robust, propping up equity markets, even as sentiment plunges to record lows amid the three-month-long Iran war. Despite gas prices soaring past $4 a gallon and what one central banker called a decade's worth of inflation hitting in half the time, the S&P 500 has rallied over 16% from its March lows, challenging economists who see the disconnect as unsustainable.

"It's a series of shocks," said Yelena Shulyatyeva, senior economist at the Conference Board. "Consumers don't get a break."

The divergence is stark: the S&P 500 is up 8% for 2026, while the University of Michigan's consumer sentiment index hit an all-time low in May. Since the start of 2020, the benchmark stock index has surged roughly 130% as the sentiment gauge collapsed by 52%. The conflict has sent U.S. crude oil up more than 60% this year, directly hitting consumers at the pump and straining global supply chains.

The resilience of the American consumer is now a critical buffer against a global recession, but its durability is in question. With the war in Iran threatening key oil routes like the Strait of Hormuz and a high-stakes U.S.-China summit looming, any crack in consumer spending could trigger a sharp market correction and force a global economic reassessment.

A Tale of Two Economies: Markets Rally as Sentiment Craters

Investors are focusing on a stellar first-quarter earnings season, where profits are on track to jump 28.6%, largely fueled by corporate spending on artificial intelligence. "We have seen this tremendous rebound as markets have willed themselves to focus on only the positive," said Kristina Hooper, chief market strategist at Man Group. This optimism stands in stark contrast to household sentiment. According to an analysis by PNC Financial Services, the pain of high prices—not the unemployment rate—is the primary driver behind the collapse in consumer confidence.

"People are starting to hear that inflation is going down, but their box of cereal is still really expensive," said economic commentator Kyla Scanlon.

That pain is now showing up in specific sectors. Whirlpool said last week it experienced a "recession-level" decline in appliance demand, while McDonald's warned that rising gas prices are pressuring customer spending. Yet, despite these warnings, broader spending continues, with companies like Uber and Walt Disney reporting strong results. "The traditional correlation between sentiment and spending has largely broken down," said Gregory Daco, chief economist at EY-Parthenon.

Japan's 4.9% Inflation Spike Shows Global Strain

The global consequences of the conflict and its impact on energy prices are becoming clearer, with import-dependent nations facing intense pressure. In Japan, wholesale prices surged 4.9% in April from a year earlier, the fastest increase in nearly three years, driven by soaring energy costs and a weakening yen.

Japan's yen-denominated import prices jumped a staggering 17.5% year-on-year, highlighting the severe impact on a country that imports almost all of its oil. The inflation shock is intensifying pressure on the Bank of Japan to consider a decisive interest-rate hike, a move that could destabilize the nation's heavily indebted economy. The situation in Japan serves as a warning for how geopolitical shocks in the Middle East can transmit into inflationary crises across the globe, particularly for energy-poor nations.

For now, the U.S. economy continues to defy the gloom. "It's a foolish man who bets against the U.S. consumer," said Eric Winograd, chief economist at AllianceBernstein. "The base case has to be that the consumer continues to plug along." But with geopolitical tensions rising and household pessimism at a record, that base case is facing its most significant test in years.
