The Labor Department reported Friday that its Consumer Price Index rose by 0.4 percent last month, double the January increase and the largest advance since a similar increase in December.
Meanwhile, the Federal Reserve said that production at factories, mines and utilities surged by 1 percent last month, a sharp rebound following a 0.3 percent drop in January.
Much of the strength came from a 6.7 percent surge in utility production, as colder-than-normal temperatures in much of the country boosted production by the biggest amount since December 1989.
Output at the nation's factories rose by 0.4 percent in February, recouping much of the 0.5 percent drop in January. Auto production was up 3.2 percent, helped by an increase in light truck manufacturing, but analysts said the domestic industry remains under severe strain from foreign competition.
A jump in computer production boosted the output of home electronics but home appliances, furniture and carpeting all suffered declines, reflecting the slump in the housing industry.
The increase in consumer inflation was larger than the 0.3 percent gain that had been forecast although excluding volatile food and energy prices, inflation was better-behaved, rising by just 0.2 percent, exactly what economists had been expecting.
"Retail sales were flat, they were actually down 0.1 percent, taking out autos in February; manufacturing looks like it's heading into reverse; housing of course is falling apart, so the real economy is extremely soft, and the inflation numbers ... well, luckily, with the CPI, the inflation is now mixed instead of bad," David Wyss, chief economist of Standard & Poor's, told CBS News.
Federal Reserve policymakers meet next Tuesday and Wednesday with the wide expectation that they will leave interest rates unchanged even though the economy has slowed significantly.
"The Fed wants that (inflation) number to be down under 2 percent, so I don't think they're going to start lowering rates until you see those numbers coming down," said Wyss. "I don't think they're going to increase rates because the economy is too weak, and inflation is not a serious enough problem to risk recession."
The overall CPI reading was slightly bigger than expected, but it was still more moderate than a huge 1.3 percent surge in wholesale prices for February, a jump that was more than double what economists had been expecting.
At the consumer level, price pressures were led by higher energy costs, which were up 0.9 percent last month after having fallen by 1.5 percent in January.
Gasoline costs rose by 0.3 percent with economists forecasting even bigger advances as the spring driving season gets under way. The latest Lundberg Survey found that the nationwide average for gasoline has risen by 20 cents per gallon in just the past two months.
Food costs shot up by 0.8 percent in February, the biggest increase in 22 months. The gain was led by 16.3 percent surge in citrus prices, reflecting adverse weather in January in California growing areas. Rising fruit and vegetable costs contributed three-fifths of February's higher food costs.
So far an expected moderation in inflation has not occurred. For the first two months of this year, consumer prices are rising at an annual rate of 3.3 percent, up from a 2.5 percent increase for all of 2006.
Core inflation, which excluded energy and food, has been rising at an annual rate of 3 percent over the past two months, far above the Fed's comfort zone for gains of 1 percent to 2 percent in core prices. Last year, core inflation rose by 2.6 percent, which was the highest reading since 2001.
The Fed raised interest rates for two years with the last rate hike occurring in June 2006 as it attempted to slow economic growth enough to dampen inflation.
Outside of food and energy, price pressures in February were seen in rising costs for shelter, medical care and clothing.
