May CPI: Inflation pressures ease on a monthly basis as tariff uncertainty lingers

May's CPI report indicated easing inflation pressures, with a 0.1% monthly increase, below expectations of 0.2%, and a 2.4% annual rise, slightly up from April's 2.3%. Core CPI also showed a modest 0.1% monthly increase, defying concerns that tariffs would accelerate price increases, as declines in car and apparel prices offset potential tariff impacts. While some economists suggest the subdued inflation may be temporary, the report reflects a period after tariff announcements, with the US and China reaching a framework to ease trade tensions, though the risk of higher prices later in the year remains.

Analysis

May's Consumer Price Index (CPI) data presented a nuanced picture of inflation, with headline CPI increasing 0.1% month-over-month, below the 0.2% rise in April and economists' forecasts of 0.2%. Annually, headline CPI rose 2.4%, a slight acceleration from April's 2.3%, which was the lowest yearly rate since February 2021. More significantly, core CPI, which excludes volatile food and energy, also rose a modest 0.1% monthly, down from April's 0.2% and beneath the anticipated 0.3% increase; the annual core rate held steady at 2.8%, contrary to expectations of 2.9%. This softer-than-expected core inflation was notably driven by declines in new vehicle prices (-0.3%) and used car and truck prices (-0.5%), categories initially expected to reflect tariff impacts. While RSM chief economist Joe Brusuelas observed minimal immediate pass-through from recent tariffs, he cautioned that significant price hikes by companies could eventually feed into consumer prices. The report captures a period approximately one month after President Trump's tariff announcements, though many subsequent "reciprocal" tariffs have been paused and a US-China framework to ease trade tensions has been agreed upon, pending final approval. However, substantial tariffs remain on Chinese goods (around 30% effective rate), along with specific duties on goods from Mexico, Canada, and on steel, aluminum, and autos globally, leading economists to maintain that the risk of higher inflation later in the year persists.

Key Decisions for Investors

• Investors should acknowledge the current easing in core inflation pressures but remain vigilant for any delayed pass-through effects of tariffs in subsequent economic reports.
• It may be prudent to evaluate sector exposures, particularly for industries like automotive and retail which have shown initial price sensitivity to trade policy and could be impacted by future tariff developments.
• Monitoring upcoming inflation data, central bank commentary, and geopolitical developments regarding trade will be crucial for assessing potential market volatility and inflationary shifts throughout the remainder of the year.
