The ongoing conflict in Iran, now more than six weeks old, has begun to ripple through the U.S. economy, manifesting in both overt and subtle ways. Soaring energy costs stand as the most immediate and visible impact, while deeper concerns about broader economic growth and persistent inflationary pressures simmer beneath the surface, challenging the fragile stability achieved in recent quarters. Despite a prevailing sentiment among most economists that the war’s direct effects on gross domestic product (GDP) may be modest—perhaps shaving off a few tenths of a percentage point overall—the pervasive uncertainty it has engendered poses a significant headwind, complicating the outlook for businesses, consumers, and policymakers alike.

A Volatile Geopolitical Landscape Meets Economic Reality

The economic repercussions of the Iran war are intimately tied to its unpredictable trajectory. A current ceasefire offers a tenuous reprieve, suggesting that the most acute inflationary impacts might dissipate if peace holds. However, the prospect of renewed hostilities looms large, threatening to plunge an already delicate economic recovery into deeper peril. As Mike Skordeles, head of U.S. economics at Truist Advisory Services, succinctly puts it, "It’s going to gouge out some of the growth, but we’ll weather through it. The bigger issue is the uncertainty." This sentiment underscores a broader anxiety that has characterized the U.S. economic landscape for much of the past year.

The roots of this uncertainty stretch back to April 2025, when President Donald Trump initiated his "liberation day" tariffs. These protectionist measures, widely interpreted as part of an increasingly muscular and aggressive foreign policy agenda, introduced a new layer of complexity to global trade relations and domestic economic planning. While the precise targets and initial economic impacts of these tariffs varied, they signaled a departure from conventional trade policies, creating an environment where geopolitical tensions could more readily translate into economic disruptions. The onset of the Iran war in mid-February 2026—following a period of escalating regional tensions—intensified these pre-existing pressures, raising critical questions about the duration of the current inflation surge, the resilience of American consumers—who account for the lion’s share of U.S. economic growth—and the disproportionate impact on energy-dependent nations globally. Underlying all these considerations is the critical question of how the Federal Reserve and other major central banks will navigate this volatile terrain.

Energy Markets Under Strain: The Immediate Shock

The most immediate and palpable effect of the conflict has been a sharp escalation in energy prices. Crude oil, the lifeblood of the global economy, surged to a peak of $115 a barrel earlier in April, before settling near $91 on Wednesday morning for West Texas Intermediate (WTI), the U.S. benchmark. This volatility has translated directly to the pump, with the national average for gasoline hitting $4.10 a gallon, according to AAA. Such elevated fuel costs act as a regressive tax on consumers, eroding purchasing power and increasing the operational expenses for businesses across all sectors, from transportation and logistics to manufacturing.

For the U.S., which has significantly bolstered its domestic energy production in recent decades, the impact is primarily a "price shock" rather than an outright "supply shock," as Skordeles notes. The nation’s enhanced energy independence has shielded it from the more severe physical shortages that might have occurred in previous eras. However, the global interconnectedness of energy markets means that even a price shock originating from a major oil-producing region like the Middle East reverberates worldwide. The potential for disruption to crucial shipping lanes, such as the Strait of Hormuz, or damage to critical production and refining infrastructure in the conflict zone, remains a significant concern that could swiftly transform a price shock into a supply crisis. Joseph Brusuelas, chief economist at RSM, drew a critical line at $125 a barrel for WTI crude, beyond which "it becomes more of an economic problem," leading to an acceleration and broadening of "demand destruction" as consumers and businesses dramatically cut back on energy consumption. While the market is currently some distance from this threshold, the specter of such an escalation underscores the precariousness of the situation.

Inflation’s Stubborn Grip and the Fed’s Tightrope Walk

The war’s influence on inflation has presented a complex picture, challenging the Federal Reserve’s efforts to steer the economy toward its 2% target. Predictably, headline inflation metrics have surged. The Consumer Price Index (CPI) for all items rose 0.9% in March, pushing the annual inflation rate to 3.3%. While this represents an unwelcome acceleration, a more granular look at "core" inflation—which strips out volatile food and energy prices to provide a clearer picture of underlying price trends—offered a glimmer of hope, with a monthly increase of just 0.2% and an annual core level of 2.6%. Similarly, the Producer Price Index (PPI), measuring wholesale price increases, accelerated 0.5% on its headline figure but only 0.1% for core, suggesting that while energy costs are clearly impacting the front lines of commerce, broader price pressures might be more contained.

These mixed signals complicate the Fed’s monetary policy calculus. Prior to 2026, the expectation was for the central bank to continue lowering interest rates to support a gradually slowing labor market. Job growth has been largely stagnant over the past year, and even negative when accounting for health care-related positions, suggesting underlying weakness that would typically warrant stimulative policies. However, the resurgence of inflation driven by the war has firmly placed the Fed in a "wait-and-see mode," according to Goldman Sachs economists Jessica Rindels and David Mericle. This delay in rate cuts, as Skordeles points out, means "elevating borrowing costs for consumers," impacting everything from mortgage rates to credit card interest and auto loans.

The market’s expectations for future rate cuts have shifted dramatically. While Goldman Sachs anticipates two cuts in September and December, driven by a forecast of rising unemployment and contained core inflation (with tariff effects waning and energy pass-through managed), current market pricing indicates no cuts until at least mid-2027. This stands in stark contrast to the Fed officials’ own projections from March, which penciled in just one reduction. This divergence highlights the deep uncertainty surrounding the war’s duration and its ultimate impact on the inflation trajectory. Any sustained spike in energy prices or broadening of supply chain disruptions could easily derail the Fed’s delicate balancing act, potentially setting off a negative chain of events throughout the year and forcing a more hawkish stance to curb inflation, even at the risk of further slowing growth.

Consumer Resilience Tested: Spending vs. Sentiment

Perhaps one of the most intriguing paradoxes emerging from the current economic climate is the stark divergence between consumer sentiment and actual spending behavior. The widely followed University of Michigan survey reported consumer sentiment at a record low in March, reaching levels not seen since the 1950s. This historic nadir surpasses periods of profound national stress, including multiple wars, the stagflation of the 1970s, the September 11, 2001 terror attacks, the Global Financial Crisis, and the COVID-19 pandemic. Such a dramatic drop typically signals deep consumer pessimism about the future economic outlook, often leading to reduced discretionary spending and a pullback in investment.

However, despite this bleak sentiment, actual consumer spending data tells a different story of surprising resilience. Debit and credit card spending surged an impressive 4.3% in March, marking the most robust increase in over three years, according to Bank of America. While a significant portion of this surge was attributed to a 16.5% jump in spending at gas stations—a direct consequence of higher fuel prices—the bank also reported "healthy growth" of 3.6% excluding gas. This suggests that American wallets, while feeling the pinch of inflation, have remained resilient enough to absorb the increased costs in other areas, indicating a continued willingness to spend on goods and services beyond essential fuel.

Several factors are likely contributing to this unexpected fortitude. One significant tailwind for consumers has been larger tax refund checks, a direct result of changes implemented in the previous year’s "One Big Beautiful Bill Act." The average tax refund this year has stood at $3,521, an 11.1% increase over the same period in 2025, according to IRS data. These larger windfalls provide a crucial injection of liquidity, helping households offset rising costs and maintain spending habits. Furthermore, David Kelly, chief global strategist at JPMorgan Asset Management, cautions against over-interpreting sentiment surveys, noting that "a fall in consumer sentiment has never been a reliable predictor of actual consumer behavior." He anticipates real consumer spending to continue growing, albeit slowly, projecting a 0.8% rise over the course of this year and 1.7% in 2027.

Nevertheless, the cumulative effect of elevated costs is not without consequence. The spike in mortgage rates, partly influenced by broader market uncertainty and the Fed’s stance, contributed to existing home sales in March falling to their lowest point in nine months. This indicates that while everyday spending remains robust, larger discretionary purchases and investments sensitive to interest rates, such as housing, are beginning to feel the strain.

Economic Growth Projections Adjust Downward

The collective impact of the war, energy price shocks, and policy uncertainty has led economists to temper their growth expectations for the U.S. economy. While a major breakdown is not anticipated, a period of slower growth appears inevitable. Goldman Sachs, for instance, recently revised its GDP forecast for the year, cutting it by half a percentage point to 2% (measured fourth quarter to fourth quarter). Similarly, the Atlanta Fed’s projection for first-quarter growth now stands at a modest 1.3%, a notable decrease from earlier estimates of 3.2%, though still an improvement over the meager 0.5% growth rate recorded in Q4 of the previous year.

This anticipated slowdown in economic activity is also expected to translate into a less robust labor market. Goldman Sachs projects that "weaker activity growth is likely to translate to weaker hiring and a higher unemployment rate," which they now foresee reaching 4.6% by year’s end—a 0.3 percentage point increase from the March level. While still relatively low by historical standards, such an increase would signify a cooling trend in job creation, potentially easing some inflationary pressures but also raising concerns about economic momentum. The critical question remains whether the economy can absorb these shocks without experiencing "structural scarring," a point Brusuelas says the U.S. has not yet reached, contingent on the extent of damage to Middle Eastern production and refining capacity. Any significant long-term damage to global energy infrastructure or trade routes could fundamentally alter economic trajectories for years to come.

Global Ramifications and Supply Chain Vulnerabilities

The economic fallout from the Iran war extends far beyond U.S. borders, with significant implications for the global economy, particularly for nations heavily reliant on Middle Eastern energy supplies. While the U.S. may primarily experience a price shock, other less energy-independent nations, notably in Europe and Asia, face the potential for more severe supply disruptions and exacerbated inflationary pressures. As Skordeles warns, "Asia is the one getting clobbered, because they’re the big users," highlighting the region’s vulnerability due to its heavy reliance on imported oil and gas to power its vast industrial base and burgeoning consumer markets. European nations, already grappling with previous energy crises, also face renewed pressure on their energy security and economic stability.

The conflict has also reignited concerns about global supply chains, which had only recently begun to normalize after the disruptions of the pandemic era. The New York Fed’s Global Supply Chain Pressure Index (GSCPI) notably surged in March to its highest level since January 2023, signaling renewed bottlenecks and increased costs for raw materials and manufactured goods. This tightening of raw material flows and the inevitable pass-through from higher energy prices could, in the coming months, amplify inflationary pressures and dampen economic activity across various sectors worldwide. Shipping costs, insurance premiums, and lead times for various components and finished goods are all subject to upward pressure. Whether these knock-on effects will significantly impact the U.S. beyond current expectations remains to be seen, but the general sentiment among economists is that the U.S., with its relatively robust domestic economy and energy production, is better positioned to weather the storm than many of its global counterparts. However, its economy is by no means immune to a slowdown in
