There are no big surprises in the numbers and the initial market reaction has been tepid. On balance, the wage and inflation numbers are fractionally higher and at a pace of +0.4% m/m, the Fed will quickly hit its 2% target.

A real gut-check moment is coming in the March-June period when base effects will lead to some high headlines. The Fed says they can look through high numbers temporarily but even a hint that they're wavering would rattle markets.

Looking at the details of this report, the energy component was a driver, up 4.0%. Food pries continue to be driving perceived inflation, up another 0.4% to bring the y/y rise to 3.9%. Used vehicle prices remain up 10.0% y/y but have fallen for three straight months.
