Policy-Relevant Inflation (PCE) Signal

Signal Summary:

• Configuration statement: Given a PCE_Composite of -0.01 and a headline Z_PCE of 0.11, this setup aligns with Range-biased price paths and Normal volatility, where the dominant risk is Mean reversion, not Regime shift. (1)
• The signal remains in a Neutral regime, though it shows a sharp month-over-month increase in headline inflationary intensity. (1)
• Conviction Band: Medium; Interpretation Confidence: High Confidence; Internal Conflict Flag: No. Signal Stability Assessment: Improving; Threshold Proximity: Moderate; Revision Sensitivity: Moderate.

Methodology Applied:

• Composite Scores between -0.75 and 0.75 define a Neutral regime where policy is likely to remain stable. (1)
• Rising values within the methodology indicate inflationary expansion and a potential hawkish bias. (1)
• The signal blends Headline and Core PCE YoY rates using robust standardisation (z-scores). (1)
• PCE Data: Latest observation 2026-03-31. (1)

Key Dynamics:

• The primary driver is a spike in Headline PCE (3.50%) which pushed the Z_PCE from -0.22 to 0.11. (1)
• Core PCE (3.20%) remains a stabilizing offset, keeping the composite score near the zero-line. (1)
• Momentum is currently strengthening, as the composite moved from -0.25 to -0.01 in the latest period. (1)
• Conditional Invalidation: A Composite Score breach above 0.75 would trigger a "Hot" regime shift. (1)

Scenario Balance:

• Base case dominant: Neutrality persists with focus on growth and employment data.
• Upside risk: Headline momentum continues, forcing a hawkish regime shift into "Hot" status.
• Downside risk: Reversion to disinflationary trends observed in mid-2025.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months) as it tracks year-over-year price changes and policy distance.
• Aggregation Weight Hint: Medium; the signal is a primary input for monetary policy forecasting.

Macro Relevance:

• Macro dimension: Pricing and Inflation.
• Economic mechanism: Measures intensity and distance-from-target to identify hawkish or dovish policy tilts. (1)
• Cycle position: Not determined by methodology.
• Typically interacts with Labor Market Slack and Dallas Fed Trimmed Mean PCE to confirm regime shifts. (1)

Regime Context:

• The Neutral regime has been persistent for over 30 months. (1)
• Direction of change: Strengthening towards the upper (Hot) threshold. (1)

Model Limitations:

• Subject to material BEA revisions and annual benchmark updates. (1)
• Lagging monthly frequency may miss real-time price inflections. (1)
