Evidence from the distributions

The distribution remains unfavorable and inconsistent with the target. This month, the distribution is highly dispersed with a very thick right tail (see ridge plot). The median (Figure 2) ticked upward. As shown in Figure 1, the overall picture remains unchanged: the distribution continues to differ from the pre-Covid pattern, with little to no progress over the past nine months. In fact, the last three months show a noticeable shift to the right. At this point it is very clear: we are in a 3% environment.

Evidence from our CI-C model

Our CI model estimates that, excluding idiosyncratic shocks, the common component remains above target. Figure 3 illustrates the decomposition of the MoM core CPI into “common” and “idiosyncratic” components. This month, the model estimates that the common component increased by 31bps, while the idiosyncratic shock contributed positively (13bps). The 3m/3m of the “common” component (Figure 4) stands at 2.94%. Overall, the CI model indicates that the “true” underlying pace of the data remains above target and close to 3%.

Note: the Figure shows the decomposition of the MoM percent changes of CPI prices excluding food and energy items. The contributions are estimated using our CI model.

Note: the Figure shows the 3m/3m at annual rate (green line), the 6m/6m at annual rate (red line), and the YoY (blue line) of the “common component” estimated using our CI model.

Implications for the medium-term forecast of core PCE price inflation

The medium-term revised up. Today’s data had a material impact on our Q1 nowcast (revised up 8 tenths QoQ saar). Also, we have revised up the path of core import prices following the tariffs anncouncements. The new (Q4/Q4) model forecast is as follows: 2.9% in 2025, 2.5% in 2026, and 2.5% in 2027. The model forecast is revised up by about 10bps as a reflection of the tariffs in 2025, while the remaining part is due to the incoming data.

Figure 5. “Main” Phillips curve model forecast, core PCE price inflation (YoY, %).

Note: the figure shows the latest run of our “main” Phillips curve model. The confidence intervals (C.I.) are estimated using quasi-out-of-sample methods (estimate the model over a sub-sample, forecast, and calculate the root mean squared forecast errors).
