The U.S. Consumer Price Index (CPI), not seasonally adjusted, inched higher in August 2026, underscoring persistent inflationary pressures in the world’s largest economy. The index rose to 334.98 in August from 333.92 in July 2026, according to data updated on 11 September 2026.
The increase of just over one point on the index reflects a continued upward trajectory in consumer prices, adding to the cumulative gains seen over recent months. While the data do not break down movements by category, the headline rise suggests that households are still facing elevated costs across a broad basket of goods and services.
Investors and policymakers will be closely watching how this latest reading feeds into expectations for future monetary policy moves, as market participants assess whether the pace of price increases is stabilizing or pointing to renewed inflation risks heading into the latter part of 2026.
