The latest US CPI report shows consumer prices rose 0.6 per cent in September, pushing annual inflation to 3.7 per cent and adding pressure to the Federal Reserve ahead of its October policy meeting.
The increase was faster than the 0.4 per cent monthly gain recorded in August.
On an annual basis, inflation accelerated from 3.4 per cent in August to 3.7 per cent in September, according to the U.S. Bureau of Labor Statistics.

Us Cpi: Gasoline was the biggest driver of the increase
Gasoline prices rose 9.1 per cent in September and accounted for more than half of the overall monthly increase in consumer prices.
The broader energy index climbed 5.2 per cent during the month after rising 2.1 per cent in August.
Energy prices were also much higher than a year earlier.
The energy index increased 20.4 per cent over the 12 months ending in September, while gasoline prices rose 34.2 per cent over the same period.
Fuel oil posted an even larger annual increase of 74.2 per cent, although it represents a smaller share of household spending than gasoline.
Core inflation also moved higher
Core CPI, which excludes food and energy prices, increased 0.3 per cent in September, matching the monthly increase in August.
On an annual basis, core inflation rose 2.6 per cent, up from 2.4 per cent in August.
The measure is closely watched because it is designed to show underlying price pressure without the month-to-month volatility of food and energy costs.
Several categories recorded monthly increases, including recreation, used cars and trucks, education, airline fares, medical care and apparel.
Communication was among the relatively few major categories to decline.
Shelter costs continued to rise
Shelter prices rose 0.4 per cent in September, following a 0.3 per cent increase in August.
Housing costs remain an important part of the inflation picture because shelter represents one of the largest components of consumer spending.
Continued increases in this category can keep inflation elevated even when some goods prices stabilize.
The September report also showed that food prices were unchanged overall.
Food consumed at home fell 0.1 per cent, while food purchased away from home rose 0.2 per cent.
Food prices were 2.5 per cent higher than a year earlier.
What the report means for the Federal Reserve
The figures arrive less than two weeks before the Federal Open Market Committee is scheduled to meet on October 27 and 28.
The Federal Reserve’s decisions are based on a broad range of data, including inflation, employment and economic activity.
A stronger-than-expected CPI reading can make it more difficult for policymakers to conclude that price pressures are returning sustainably toward their longer-run objective.
The CPI report does not determine the Fed’s interest-rate decision by itself.
Officials will also assess other inflation measures, labour-market conditions, consumer spending and financial conditions before announcing their next policy decision.
The central bank’s October meeting is scheduled to conclude with a policy statement and press conference on October 28.
What consumers may notice
For households, the sharpest immediate effect is likely to come through fuel costs.
Higher gasoline prices can raise commuting expenses and increase transportation costs for businesses that pass those expenses through to customers.
Energy prices can also affect inflation indirectly because fuel is used to move goods, operate buildings and provide services.
The report does not mean every household experienced a 3.7 per cent increase in expenses.
The CPI is an average measure based on broad consumer spending patterns, while individual households face different costs depending on housing, transportation, food and health-care needs.
