Inflation
March U.S. inflation showed a surprise dip, with headline CPI falling 0.1% MoM and core CPI at 2.8% YoY, though tariffs could drive future price hikes.
The March U.S. Consumer Price Index delivered an unexpectedly subdued reading, offering a brief reprieve amid persistent inflationary concerns. Headline CPI declined by 0.1% month-on-month (MoM)—its first negative monthly print since May 2020—while core CPI, which excludes food and energy, rose just 0.1% MoM, the slowest pace since March 2021. On a year-over-year (YoY) basis, headline inflation slowed to 2.4%, below the consensus forecast of 2.5% and down sharply from 3.2% in February, while core CPI eased to 2.8% YoY, falling below the 3% threshold for the first time in over three years. The “supercore” measure, which excludes housing from services, dropped 0.1% MoM—the steepest decline since the COVID-19 lockdowns—bringing its annual rate down to 3.22%, the lowest since December 2021. These softer prints were driven by notable price declines across key categories: gasoline fell 6.1% MoM, airline fares dropped 5.3%, recreation slipped 0.1%, used vehicle prices declined 0.7%, and medical care commodities plunged 1.1%, including a 2.0% decrease in prescription drug prices. Overall energy prices were down 2.4% MoM. However, the outlook for inflation remains uncertain as cost pressures loom from newly announced tariffs—such as the 25% levy on foreign autos and China’s retaliatory 125% import duty—which are likely to disrupt supply chains and raise input costs across sectors. These factors could drive renewed upward momentum in prices, particularly in vehicles, parts, and services like repairs and insurance, undermining the recent softness and keeping inflation volatility—and Federal Reserve rate expectations—in sharp focus.
We believe the economy is showing signs of weakness, and despite the tariffs that Trump is playing with—now paused for 90 days, except in China—inflation may not rise as sharply as before. However, we expect inflation to remain volatile.
