Consumer price index data shows a 3.4% annual increase, contradicting recent political claims of price declines.

The consumer price index rose 0.4% in August. This puts the 12-month increase at 3.4%, according to the Bureau of Labor Statistics. The data contradicts recent statements by President Trump, who claimed prices are dropping fast. This statement was made one month after a similar claim that inflation was way down.

Core CPI, which excludes food and energy, rose 0.3% last month. This figure was worse than market expectations. Inflation has now climbed faster than wages for the fifth consecutive month. This trend squeezes consumers facing an affordability crisis.

Core Inflation Outpaces Wage Growth

The rise in core prices signals persistent cost pressures. The Federal Reserve uses this metric to gauge underlying inflation trends. A 0.3% monthly increase indicates that the disinflationary trend has stalled. The gap between price growth and wage growth continues to widen.

Justin Wolfers, an economist at the University of Michigan, described the rate of price increases as uncomfortably high. The data aligns with previous discouraging reports on producer prices. The personal consumption expenditures index also showed similar stubborn trends.

Oil Prices Threaten Further Increases

Brent crude oil prices rose 15% in September. The international benchmark reached roughly $105 per barrel. These energy costs have not yet fully impacted the August CPI data. The lag means September inflation figures may be even higher.

The New York Times noted that these stubborn numbers predate the recent oil surge. Higher energy costs typically flow through to gasoline and other petroleum products. This creates a headwind for any future disinflation. The current data suggests a difficult path for the Federal Reserve.

Political Narrative Clashes With Data

President Trump told reporters on a tarmac that prices are dropping fast. This remark contradicted the official statistics released by the Bureau of Labor Statistics. The administration has repeatedly asserted that inflation is under control. The latest figures challenge this narrative.

Telling Americans to ignore their wallet data is a risky strategy. This is especially true in an election year. The market desk reports that the data remains the primary source of truth. The source GN markets/inflation (en-US) confirms the upward trend in consumer prices.
