The ranges of estimates are important in terms of market reaction because when the actual data deviates from the expectations, it creates a surprise effect. Another important input in market's reaction is the distribution of forecasts. In fact, although we can have a range of estimates, most forecasts might be clustered on the upper bound of the range, so even if the data comes out inside the range of estimates but on the lower bound of the range, it can still create a surprise effect.CPI Y/Y 2.8% (2%)2.7% (47%) - consensus2.6% (43%) 2.5% (6%) 2.4% (2%) CPI M/M0.4% (6%)0.3% (65%) - consensus0.2% (25%) 0.1% (4%)Core CPI Y/Y3.1% (2%)3.0% (49%) - consensus2.9% (45%) 2.8% (4%) Core CPI M/M0.4% (4%) 0.3% (66%) - consensus0.2% (27%)0.1% (3%)As always, the focus will be on the Core figures. We can notice that we have forecasts clustered around 2.9-3.0% for the Y/Y and 0.2-0.3% for the M/M measure. Therefore, the biggest moves will be triggered by deviations from these figures as there's very low consensus of overshoots or undershoots.
