Following a quiet overnight session in which the main event appears to be a statement by Chinese premier Li for more active fiscal policy, which has pushed the metals complex higher, although technically every other asset class as well, with US equity futures set to open in fresh record high territory, even as 10Y yields around the world continue to decline, attention today will fall on the CPI print due out shortly, because if consensus is correct, January will be the first month this decade when US inflation posts a negative print, mostly due to the delayed effect of sliding commodity prices. As Deutsche recaps, the most important number today is the headline CPI where the headline YoY rate is predicted to be negative by the market (-0.1%) for the first time since 2009. Over this period the YoY rate stayed negative for 8 months. However before this we hadn't seen a full year decline since August 1955. In other words, a few months before what may be the first US rate hike for a new generation of traders, the US is set to print its first annual deflation since Lehman, transitory or not.
