Recently, U.S. producer prices rose sharply, driven by escalating energy costs linked to the Iran conflict. The Labor Department revealed that the producer price index increased by 6.5% from May 2025, with a monthly rise of 1.1% from April, matching the previous month’s growth.

Wholesale gasoline prices soared, exceeding 23% from April to May, and almost 70% compared to last year. These inflationary pressures, intensified by the energy shock, are causing concern among Americans as midterm elections approach. President Donald Trump’s Republicans face potential challenges in maintaining control of Congress.

While gasoline prices have slightly decreased, the cost of regular gasoline remains above $4 per gallon since March, as reported by AAA. The U.S. driving season, which traditionally increases prices, has begun.

Core wholesale prices, excluding volatile food and energy sectors, rose 0.4% from April and 4.9% from May 2025. These numbers followed the Labor Department’s report of consumer prices rising 4.2% in May from a year earlier, marking the highest increase in three years.

Airfares increased nearly 27% from May 2025. Inflation continues to exceed the Federal Reserve’s 2% target. Although the Fed is likely to maintain its benchmark interest rate at next week’s meeting, financial markets predict a potential rate hike by year’s end to counter price rises.

Wholesale prices are key indicators for future consumer inflation. Economists monitor these figures, as some components like health care and financial services, influence the Fed’s favored inflation measure — the personal consumption expenditures (PCE) index.

Stephen Brown, chief North America economist at Capital Economics, mentioned, “Producer prices that feed into the PCE price calculation rose more than anticipated, supporting our view that the Fed will hike interest rates by year-end.”

After the February 28 attack by the U.S. and Israel, Iran closed the Strait of Hormuz, leading to a significant disruption in oil supplies. Energy prices surged as a result. S&P Global Energy highlighted that U.S. crude oil inventories are depleting as the summer driving season nears.

The bottom line is that U.S. inventory levels remain above estimated minimum operating thresholds, said Aaron Brady of S&P Global Energy. However, due to ongoing disruptions in Middle Eastern oil flows, inventory draws may persist into the third quarter, even if a diplomatic resolution is reached soon. Significant, sustained inventory decreases could indicate a ‘danger zone’ for the U.S. refining system.
