Ahead of CPI report analysts at Pierpont Securities say: "The key question for Jan CPI is whether core prices continue to move up slowly or accelerate further." A +0.2% could be "a shot across the bow for an FOMC that just marginally lowered its core inflation projections for both 2011 and 2012. The headline CPI may have increased by 0.3% in January, driven mainly by a jump in gasoline and heating prices."
