The consumer price index is forecast to hit 4.2 percent in May, marking the highest annual inflation rate in three years and a significant acceleration from April’s 3.8 percent, according to economists and financial analysts surveyed ahead of the report’s release on Wednesday.
The expected 4.2 percent year-over-year increase would represent the highest level since April 2023, when inflation reached 4.9 percent, according to Trading Economics and multiple financial outlets. The month-over-month rise is expected to reach 0.5 percent, up from April’s 0.6 percent monthly gain.
Energy prices are the dominant driver of the anticipated May inflation surge. US energy inflation soared to 17.9 percent year-over-year in April 2026, up from 12.5 percent in March, marking the steepest annual increase since September 2022, according to Trading Economics. Higher energy prices accounted for 40 percent of the total jump in inflation in April, according to Yahoo Finance analysis of the consumer price index data.
The Center for Economic and Policy Research identified energy prices, especially gasoline, as the expected biggest driver of May inflation, with food inflation remaining elevated due to tariffs. Geopolitical tensions linked to Middle East conflicts have contributed significantly to these energy price spikes, pushing gasoline and broader energy costs higher across the economy.
Core inflation, which excludes volatile food and energy prices, is forecast to rise more modestly to 2.9 percent on an annual basis in May, according to CBS News, suggesting that much of the overall inflation acceleration is concentrated in energy-dependent sectors rather than spreading broadly through the economy.
Consumer inflation expectations remain relatively stable despite the headline number. The Federal Reserve Bank of New York’s May 2026 survey shows median one-year-ahead inflation expectations at 3.5 percent, down 0.1 percentage point from prior readings, and five-year-ahead expectations unchanged at 3.0 percent, according to Trading Economics. This suggests households and analysts expect inflation to moderate after the current energy-driven spike.
The Federal Reserve has maintained its benchmark interest rate in the 3.50 to 3.75 percent range as it continues to move toward its 2 percent inflation target, according to Reuters. Market pricing implies roughly a one-in-three chance of a rate hike before year-end, according to ABA Banking Journal analysis, though the Fed is expected to hold rates steady at its June meeting.
