The pace of inflation on the consumer level picked up in September, but remained relatively mild compared to monthly spikes earlier in the year.
The government said the consumer price index rose 0.2%, matching the consensus forecast of economists but up slightly from August's 0.1% rate.
If there was cause for concern, it can be found in the 0.3% increase in so-called core, which excludes the impact of energy and food costs. It was slightly more than expectations and three times the pace of the previous three months of gains.
Energy costs fell 0.4%, the third consecutive monthly decline, after advancing sharply in the first half of the year.
Medical care, transportation and education costs showed the biggest increases; all rose 0.4%.
The CPI report largely mirrors price data found in the producer price index report last week and is unlikely to spark concerns about widespread price pressures in the economy, despite soaring oil prices.
