Inflation is projected to climb above 4% for the first time in three years, driven by an oil price shock linked to the ongoing conflict in Iran, according to FactSet estimates. This trend threatens to erode household purchasing power as the cost of energy and essential goods rises faster than typical paychecks.
Why is inflation rising again?
The primary driver behind the current inflationary pressure is the volatility in energy markets. According to FactSet, the war in Iran has triggered an oil price shock that is expected to push the Consumer Price Index (CPI) above 4% in the coming months. Economists project a 0.5% increase in monthly inflation, with an annual rate reaching 4.2%. This creates a statistical throwback to 2021 and 2022, when inflation surged toward a four-decade high of 9.1%.

While inflation is rising, economists at FactSet suggest this cycle will likely be less severe than the 2021 surge. Current projections estimate the CPI will peak between 4.5% and 5% for the year, significantly lower than the 9.1% peak recorded during the previous inflationary period.
How does inflation affect real wages?
Real wages—pay adjusted for inflation—are currently declining as price increases outpace salary growth. If the CPI hits the projected 4.2% mark, real wages will effectively shrink at an annual rate of 0.8%, according to data analysis of current economic trends. This widening gap between income and the cost of living places significant affordability pressure on American households, particularly for essential services and goods.
Which sectors are seeing the highest price hikes?
Beyond energy, the impact of rising costs is most visible in transportation-heavy sectors. Data from April shows that fruit and vegetable prices rose by 2.3%, marking the largest monthly increase for that category since 2010. According to market reports, tomato prices have surged by more than 15% for two consecutive months. These increases are largely attributed to the rising cost of diesel fuel, which powers the refrigerated trucks used to transport fresh produce.
Core Inflation vs. Volatile Goods
While food and energy prices remain volatile, “core” inflation—which excludes these categories—is showing more stability. Economists expect core inflation to rise by 0.3%, with the annual rate ticking up slightly to 2.9% from 2.8% the previous month. This suggests that while external shocks are driving the headline numbers, underlying price pressures remain relatively contained.
To manage personal budgets during periods of high inflation, track your “core” spending separately from volatile categories like gasoline and fresh produce to better understand your baseline financial health.
Frequently Asked Questions
- Why are food prices rising so quickly?
- Rising diesel fuel costs have made the transportation of goods, especially refrigerated perishables like fruits and vegetables, significantly more expensive, according to recent Bureau of Labor Statistics data.
- How does this inflation compare to 2021?
- While current trends echo the 2021 surge, analysts expect a milder outcome this time, with projections peaking near 5% rather than the 9.1% seen in the previous cycle.
- What are real wages?
- Real wages refer to your income adjusted for inflation. When inflation rises faster than your paycheck, your real wages decline, meaning your money buys fewer goods than it did previously.
