The Consumer Price Index for All Urban Consumers increased 0.5% on a seasonally adjusted basis in January, after rising 0.4% in December, the U.S. Bureau of Labor Statistics reported today.

The producer price index for final demand climbed 0.4% from a month earlier, and that after an upwardly revised 0.5% increase in December, the Bureau of Labor Statistics said Thursday. The data on wholesale prices comes just a day after a consumer price index report showed underlying inflation at its highest in more than a year.

U.S. inflation accelerated last month as the cost of groceries, gasoline and rents rose, a disappointment for families and businesses struggling with higher costs and likely underscoring the Federal Reserve's resolve to delay further interest rate cuts.
