US Consumer Prices Drop For First Time Since 2020
US consumer prices fell 0.4% month-over-month in June 2026, reversing May’s 0.5% rise and surpassing expectations of a 0.1% drop. This was the first monthly decline since May 2020 and the largest since April 2020, primarily due to a 5.7% drop in energy prices as crude prices fell from multi-year highs. Energy prices had previously risen 3.9% in May, 3.8% in April, and 10.9% in March. Additional downward pressure came from motor vehicle insurance, communication, apparel, medical care, and used cars and trucks. Food prices, however, rose 0.2%, with both food at home and away from home increasing equally. Other rising categories included recreation, household furnishings and operations, and personal care. The core CPI, which excludes food and energy, remained unchanged, below forecasts of a 0.2% rise.
