US: February 2024 CPI – Nailed It!

Nailed It! But That’s the Problem..

Evidence from the distributions

Distribution, still unfriendly. This month, all percentiles of the distribution moved down, except for the left tail (ridge plot here). The median (Figure 2) moved down compared to January but remains very elevated.

In the last three months (black line in Figure 1) the distribution shows only limited progress, in fact it shows some movements to the right. The shape of the distribution continues to be different than pre-Covid. For this reason, as we wrote in previous notes, we remain careful in declaring victory or claiming that 2% is around the corner. It cannot be done right now. If anything, the evidence in Figure 1 indicates that the US economy continues to be more consistent with an inflation rate above target going forward.

Please, note that the last paragraph is identical to what we wrote last month and the previous several months. On the other hand, the distribution in PCE space is more friendly. Put it simply: the distribution in core CPI space suggests a 3%+ reading, while in core PCE space it suggests around 2.5%. If the reader is still unconvinced, another way of putting it is the following: we need to disinflate services ex rents/OER and they are still accelerating (see here the metrics).

Note: the Figure shows the fitted Kernel (Epanechnikov) distribution of MoM percent changes at annual rate of CPI prices excluding food and energy items.

Figure 2.  Median (core) CPI metrics

Note: the Figure shows the median (MoM %, a.r.) of the distribution of CPI prices changes excluding food and energy items (left panel) and the YoY (right panel).

Evidence from our CI-C model

Our CI model estimates that net of Covid and idiosyncratic shocks, the common component in February is strong. Figure 3 shows the decomposition of the MoM of core CPI in the “common” vs “idiosyncratic” component.  The model estimates that in February the common component increased by 32bps, while the idiosyncratic shock is also positive (4bps). The common component expanded at a solid pace. The 3m/3m of the “common” component (Figure 4) is on a downward trend but likely to rebound in the coming months. Overall, the evidence of the CI model suggests that the “true” underlying pace of the data remains above target.

Figure 3. Contributions to MoM changes of CPI excluding food and energy items (CI-C model)

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-C model, a 2-stage OLS-LASSO regression model.

Figure 4. Estimated “Common” component: YoY, 3m/3m a.r. and 6m/6m a.r.

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-C model.

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

The medium-term forecast of core PCE price inflation is a bit stronger. Compared to last run, the model forecast is a bit stronger due to higher incoming data. We are working under the Q1 nowcast of 3.5% (QoQ saar). Conditional on this, the model forecast is: 3.1% (Q4/Q4) in 2024, 2.7% in 2025, and 2.65% in 2026. This forecast is now above the latest SEP at every horizon. We will finalize the forecast later today.

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).

Implications for the Fed Board staff and the FOMC

Higer FF rate in SEP in 2024? The problem is not today’s CPI. The problem is bigger. In this cycle, we have been on the (very) inflationista/hawkish side. We turned more dovish toward the end of last year when the core PCE distribution started to cooperate. But, if anything, the problem in core CPI only got worse in recent months. As we will show tomorrow, the risk is that the new SEP might show one cut less in 2024 compared to December.
