Policy-Relevant Inflation (PCE) Signal

Signal Summary:

• Configuration statement (mandatory): Given a PCE_Composite of -0.23, headline PCE_YoY of 2.83%, and CorePCE_YoY of 3.06%, this setup aligns with Range-biased price paths and Normal volatility, where the dominant risk is Mean reversion, not Regime shift. (1)
• The signal is currently in a stable Neutral regime, having transitioned from a Hot regime in late 2023. (1)
• Conviction Band: Medium; Interpretation Confidence: High Confidence; Internal Conflict Flag: No. Signal Stability Assessment: Stable; Threshold Proximity: Far; Revision Sensitivity: Moderate.

Methodology Applied:

• Composite scores between -0.75 and 0.75 are classified as Neutral, suggesting no immediate policy bias. (1)
• The "Level_pp > 0" rule identifies that inflation exceeding the 2% target creates structural pressure for restrictive rates. (1)
• Momentum is used as an early warning for regime transitions toward Hot or Cool states. (1)
• Policy-Relevant Inflation (PCE) Signal; Latest observation: 2026-01-31. (1)

Key Dynamics:

• The primary driver is the stabilization of both Headline (-0.22 Z-score) and Core (-0.25 Z-score) inflation within historical norms. (1)
• Inflation remains above the 2% policy target, maintaining a floor under restrictive monetary policy expectations. (1)
• Momentum has flattened, with the PCE_Composite showing negligible change from the prior month (-0.234 vs -0.226). (1)
• Conditional Invalidation: A PCE_Composite move exceeding 0.75 would trigger a transition back to a Hot regime. (1)
• The signal has shown high persistence, remaining in the Neutral regime for over 28 consecutive months. (1)

Scenario Balance:

• Base case dominant: Continued Neutral regime persistence as inflation levels oscillate slightly above the 2% target.
• Upside risk: A re-acceleration in consumer demand or energy shocks pushing the composite toward the 0.75 "Hot" threshold.
• Downside risk: Rapid labor market softening causing a transition toward the -0.75 "Cool" disinflationary threshold.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months), reflecting the typical lag in PCE data and central bank reaction functions.
• Aggregation Weight Hint: Medium, as PCE is the Federal Reserve's primary inflation gauge but currently lacks trend momentum.

Macro Relevance:

• Informs the pricing of real rates and the Federal Reserve's "higher for longer" policy stance.
• Implies an economic transmission mechanism where residual labor market tightness sustains core inflation above target. (1)
• Cycle position: Not determined.
• Interacts with 10Y Breakeven Inflation and Unemployment rates to validate the sustainability of the current inflation path. (1)

Regime Context:

• Regime persistence is high; the signal has occupied the Neutral zone since September 2023. (1)
• Direction of change: Stabilising within the Neutral band.

Model Limitations:

• Subject to material BEA revisions and monthly reporting lags. (1)
• Z-scores may be distorted by historical structural breaks in inflation volatility. (1)
