US April PPI Falls 0.5%, Largest Monthly Drop in Five Years
Data released by the US Bureau of Labor Statistics on May 15 shows that the PPI in April decreased by 0.5% month-on-month, far below the market's expected increase of 0.2%, marking the largest monthly drop since 2019. The core PPI (excluding food and energy) also fell by 0.4%, the largest drop since 2015. The decline in PPI was mainly influenced by falling service prices, particularly a 6.9% drop in portfolio management fees, a 3.1% decrease in hotel accommodation prices, and a 1.5% decline in airline fares.
According to the US Department of Labor, the final demand service prices fell by 0.7%, the largest drop since the category began being tracked in 2009. Most of these service items fall under the core personal consumption expenditures (PCE) inflation indicator, which the Federal Reserve closely monitors, indicating that inflationary pressures continue to ease.
