Tariffs seen lifting underlying US consumer prices in May

U.S. consumer prices likely rose moderately in May, with economists anticipating that tariffs implemented by the Trump administration began impacting prices beyond gasoline, potentially increasing underlying inflation pressures. The core CPI, excluding volatile food and energy components, is expected to show the largest increase in four months, with retailers like Walmart already indicating price increases; however, the Bureau of Labor Statistics faces staffing challenges that have led to the suspension of CPI data collection in some cities and raised concerns about data quality, though officials maintain published data meets rigorous standards.

Analysis

U.S. consumer prices are anticipated to have shown a moderate increase in May, with the overall Consumer Price Index (CPI) likely rising 0.2% month-over-month and 2.5% year-over-year, influenced partly by lower gasoline prices. However, a more significant development is the expected acceleration in the core CPI, which excludes food and energy, projected to climb 0.3% month-over-month – its largest gain since January – and 2.9% year-over-year. Economists attribute this underlying inflationary pressure primarily to the initial impact of the Trump administration's import tariffs, with major retailers like Walmart already signaling price increases commencing in late May and June. This suggests May could mark the beginning of a period of tariff-induced higher inflation readings potentially extending through year-end. Compounding these economic considerations are emerging concerns regarding the integrity and scope of U.S. economic data, as the Bureau of Labor Statistics (BLS) has suspended CPI data collection in three cities and plans to cease publishing approximately 350 Producer Price Index (PPI) series due to severe resource constraints, including a reported 15% reduction in staffing. While the BLS maintains its published data meets rigorous standards and national-level CPI reliability is currently deemed stable by some experts, the reduction in data granularity and the increased use of imputation methods raise questions about the future accuracy and comprehensiveness of key economic indicators, which the Federal Reserve will be closely monitoring as it considers monetary policy amidst these tariff impacts.

Key Decisions for Investors

• Investors should monitor upcoming inflation reports closely for evidence of sustained tariff pass-through, which could impact corporate profitability and consumer spending patterns.
• Consider the heightened uncertainty surrounding economic data quality from the BLS, potentially affecting market volatility and the clarity of Federal Reserve policy signals.
• Evaluate portfolio exposure to sectors most sensitive to import tariffs and rising input costs, such as retail and manufacturing, and assess companies' pricing power in this inflationary environment.
