The U.S. Consumer Price Index (CPI) report scheduled for release on April 10 is expected to show inflation accelerating to a 3.3% annual pace in March, marking the highest rate since May 2024. This increase represents an almost one percentage-point rise from February, driven primarily by a sharp surge in energy prices amid heightened tensions related to the Iran war.
Energy Prices and Inflationary Impact
Experts attribute the jump in inflation to rising fuel costs, with March registering the largest one-month gasoline price increase since at least 1957, according to Pantheon Economics. Oxford Economics anticipates that headline CPI inflation will exceed 3% for March and could surpass 4% in April as the conflict continues to disrupt global energy supplies.
The war’s impact on the global energy market has not only raised gas prices but also affected transportation and production costs of various goods, including food. Economists describe this dynamic as the “rockets and feathers” effect, where energy prices spike rapidly during supply disruptions but decline more slowly afterward.
Broader Economic Effects and Consumer Concerns
Rising fuel costs are contributing to higher prices for airline tickets, groceries, and other consumer goods, adding pressure on household budgets. Moody’s Analytics chief economist Mark Zandi noted that consumers are likely to face elevated costs “through much of the year” as these inflationary pressures persist.
The ongoing inflation increase follows a period of relative cooling earlier in 2026, when inflation averaged 2.4%. Although this was still above the Federal Reserve’s 2% target, it was well below the 40-year high of 9.1% recorded in June 2022. However, consumer price pressures were already evident before the Iran conflict escalated, with the Personal Consumption Expenditures price index rising 0.4% in February compared to the previous month.
Financial strain among households has been growing, as indicated by increased 401(k) hardship withdrawals and rising loan delinquencies in 2025. The conflict’s inflationary effects, combined with existing affordability challenges, risk further eroding consumer spending—a critical component of economic growth.
Federal Reserve and Future Policy Considerations
The Federal Reserve is monitoring inflation developments closely, with expectations shifting away from planned interest rate cuts this year in light of the renewed inflationary risks. Minutes from its March meeting suggest some policymakers are even considering the possibility of future rate hikes if inflation remains elevated.
Despite these challenges, one moderating factor is the decline in tariffs imposed during the Trump administration, which have decreased from a peak effective rate of 21% in April 2025 to around 8%, reducing their inflationary impact.
Why it matters
The resurgence of inflation, fueled by geopolitical tensions and energy supply disruptions, poses risks to economic stability and household finances. Rising prices can dampen consumer spending, which makes up about 70% of U.S. GDP, potentially slowing economic growth. The Federal Reserve’s policy decisions in response to these inflation trends will be closely watched for indications of how they plan to balance inflation control with economic expansion amid ongoing global uncertainties.
