Inflation Cools to 3.5% in June After US-Iran Peace Deal Relief 2026

Inflation cooled to an annual rate of 3.5% in June, driven by a brief US-Iran peace deal that temporarily lowered energy prices, according to new data from the Bureau of Labor Statistics. The consumer price index (CPI), which measures a basket of goods and services, had been elevated since the start of the war, largely because of higher energy costs. After mostly staying under 3% since mid-2024, CPI reached a three-year high of 4.2% in May, up from 2.4% in February.

Month-over-month, CPI fell 0.8% in June, the largest one-month decrease since April 2020. Declines in the energy index were the biggest contributor, offsetting increases in other categories like food, utilities, and shelter. Gasoline prices dropped 9.7% from May to June, while fuel oil—including diesel and kerosene—fell 9.2%. Apparel also ticked down 0.6%.

Core Inflation and Federal Reserve Outlook

Stripping out volatile energy and food prices, core inflation—which the Federal Reserve watches closely—decreased slightly to 2.6% on a yearly basis and remained flat from the previous month. This suggests that underlying price pressures are easing, though not as dramatically as the headline number. The Fed may still hold off on rate cuts until more data confirms the trend.

Energy Prices and Global Impact

Though the US-Iran peace agreement brought temporary relief, recent strikes between the two countries have sent oil prices climbing again. Donald Trump said on Monday that the Strait of Hormuz, where a fifth of the world’s oil and gas typically passes through, will remain open “with or without Iran” and claimed the US will reinstate its blockade of Iranian ports. In response, Brent crude hit $80 on Monday, after reaching a recent low of $67 earlier in July.

Prices at the pump have also risen: the national average for a regular gallon of gas increased to $3.87 last week, $0.70 more than a year ago. Higher energy costs have trickled into other industries, including travel. Delta said in its quarterly earnings last week that it expects high airfares to persist and has passed on 60% of fuel cost increases to customers.
