US Inflation Reaccelerates to 3.7% in September on Energy Surge

The US Consumer Price Index for All Urban Consumers climbed 0.6% on a seasonally adjusted basis in September 2026, pushing the annual inflation rate to 3.7% ¹. The 12-month figure accelerated from the 3.4% annual rate recorded in August, according to the US Bureau of Labor Statistics ¹.

Surging fuel costs were the primary driver of the headline expansion. The energy index advanced 5.2% over the month, propelled by a 9.1% jump in gasoline prices that accounted for more than half of the total monthly increase ¹. On a 12-month basis, energy costs surged 20.4%, with gasoline climbing 34.2% ¹. Shelter costs also added upward pressure, rising 0.4% in September and 3.2% year-over-year ¹. In contrast, the overall food index remained unchanged on the month, as a 0.1% decline in grocery expenses counterbalanced a 0.2% increase in dining out ¹.

Core Inflation Holds Steady

The core index, which excludes volatile food and energy components, increased 0.3% in September, matching its August pace ¹. Over the past 12 months, core CPI climbed 2.6%, up slightly from 2.4% in August ¹. Monthly increases across recreation, used vehicles, and education offset minor declines in communication and prescription drugs ¹.

The uptick in headline inflation arrives amid sustained pressure across broader financial markets. Digital assets have trended lower in recent sessions, with $BTC slipping toward $81,824 and $ETH trading around $2,419 at the time of writing, following a broader pattern detailed in earlier market closes.

The Bureau of Labor Statistics is scheduled to publish its October 2026 consumer price data on Nov. 10 ¹.
