April CPI data may indicate inflationary pressure amid technical adjustments.

In his research report on May 12, Stephen Innes forecasted that the nominal CPI increased 0.6% month-over-month in April, with core CPI rebounding from 0.2% to 0.4%. Market expectations ranged from 0.4% to 0.8%, with energy market volatility and service inflation adding uncertainty. The report noted that the stronger core inflation was primarily due to a technical revision by the Bureau of Labor Statistics for October data of last year; excluding rent adjustments, core CPI may have been only 0.24%. Housing inflation is expected to rebound due to sampling adjustments, with owner’s equivalent rent and primary rent rising 0.5% and 0.44%, respectively. Airfare is forecasted to rise 3% month-over-month, while used car prices are expected to fall 0.4% and auto insurance rates to increase 0.4%. Due to a methodological update, health insurance costs are projected to decline 1.5% monthly over the next six months. AI Interpretation: The month-over-month growth in CPI exceeded market expectations, signaling heightened inflationary pressures. The rebound in core CPI indicates that, despite technical adjustments, inflation remains on an upward trajectory. Rising prices in housing and services further confirm the persistence of inflation, which will influence market expectations for future monetary policy. Overall, this data is likely to reinforce market expectations that the Federal Reserve will maintain high interest rates.
