WASHINGTON (AP) — Higher gas costs drove up U.S. consumer prices in September for the second straight month. Outside energy, there was little sign of inflation.
The Labor Department said Tuesday that the consumer price index rose a seasonally adjusted 0.6 percent last month, matching the August increase. In the past 12 months, prices have increased 2 percent. That's in line with the Federal Reserve's inflation target.
Excluding volatile food and energy costs, prices rose just 0.1 percent. In the past year, so-called core prices have increased 2 percent.
"Pump prices are fueling headline inflation, but underlying ... trends remain benign," Robert Kavcic, an economist at BMO Capital Markets, said in a note to clients.
Modest inflation leaves consumers with more money to spend, which can boost growth. Low inflation also allows the Federal Reserve to continue with its efforts to rekindle the economy. If the Fed were worried that prices are rising too fast, it might have to raise interest rates.
The small increase in prices prompted the government to raise Social Security benefits 1.7 percent next year for 56 million recipients. The government increases benefits each year if prices rise.
Next year's increase is among the smallest since automatic adjustments began in 1975. Benefits rose 3.6 percent in 2012. There were no increases in the previous two years.
Still, the boost will give elderly Americans and other recipients a bit more buying power. Social Security payments for retired workers average $1,237 a month, or about $14,800 a year. A 1.7 percent rise is equal to about $21 a month, or $252 a year, on average.
The government's report showed that food prices rose only 0.1 percent. The cost of meat, chicken and eggs fell. Dairy prices rose.
Gas prices rose sharply over the summer and into September, but have since come down. The average price for a gallon of gas nationwide was $3.77 on Tuesday, about 9 cents below last month's level.
Tuesday's report noted that gas prices rose a seasonally adjusted 7 percent in September, below August's 9 percent increase.
Paul Ashworth, an economist at Capital Economics, said that with gas prices leveling off, overall inflation should stabilize at around 2 percent for the next several months and then decline.
