Wholesale prices rose at a faster-than-expected pace in January, countering hopes that inflation was easing, the Bureau of Labor Statistics reported Friday. The Producer Price Index which excludes volatile food and energy prices, increased a seasonally adjusted 0.8%, more than the 0.6% gain in December and well ahead of the Dow Jones consensus estimate for 0.3%. On an all-items basis, the headline PPI rose 0.5%, also above the forecast for 0.3% and 0.1 percentage point more than the prior month.
