Explicit Slack Gap Signal

Signal Summary:

• Configuration statement: Given a UNRATE of 4.3% and an NROU estimate of 4.40%, this setup aligns with Indeterminate price paths and Indeterminate volatility, where the dominant risk is Data uncertainty, not Mean reversion. (1)
• The signal currently occupies a NEUTRAL regime with WIDENING momentum, indicating a transition away from previous labour tightness. (1)
• Conviction Band: Low; Interpretation Confidence: Low Confidence; Internal Conflict Flag: Yes. Signal Stability Assessment: Volatile; Threshold Proximity: Near; Revision Sensitivity: High.

Methodology Applied:

• Regime classification: Tight (SlackGap ≤ -0.50 pp), Slackening (≥ +0.50 pp), or Neutral (otherwise). (1)
• Momentum classification: Widening (≥ +0.20 pp change over 3 months) or Narrowing (≤ -0.20 pp). (1)
• Confidence is downgraded to Medium if the absolute gap is below 0.25 pp due to estimation uncertainty. (1)
• Latest observation: 2026-01-31; Data timeliness cannot be assessed. (1)

Key Dynamics:

• The SlackGap of -0.10 pp places the signal in a Neutral regime, but a 3-month change of +0.31 pp triggers a "Widening" momentum flag. (1)
• The internal conflict arises from a neutral level paired with rapid momentum toward slackening. (1)
• Conditional Invalidation: A move in the SlackGap to ≥ +0.50 pp or ≤ -0.50 pp. (1)
• Signal stability is low; the gap has transitioned from -0.41 pp to -0.10 pp over two quarters. (1)

Scenario Balance:

• Base case dominant; risks balanced as the gap resides in the near-neutral zone.
• Upside risk: Tightening regime re-entry if UNRATE falls below 3.9% relative to current NROU.
• Downside risk: Slackening regime entry if momentum persists, pushing the gap above +0.50 pp.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months) as it anchors structural labour capacity benchmarks. (1)
• Aggregation Weight Hint: Medium; it serves as a canonical anchor for Fed reaction-function modelling. (1)

Macro Relevance:

• Informs the Labour Market dimension, specifically measuring excess supply versus structural norms. (1)
• The transmission mechanism operates via potential pressure on wage growth and central bank policy stances. (1)
• Cycle position: Not determined.

Regime Context:

• Persistent Neutral regime; however, recent data shows a weakening trend (widening gap). (1)
• Direction of change: Weakening (moving from tighter toward structural parity). (1)

Model Limitations:

• NROU is a model-based estimate subject to revision by the Congressional Budget Office. (1)
• Gap values near zero reflect elevated estimation uncertainty. (1)

Data & References:

• Latest Data: UNRATE (4.3%), NROU (4.40%), SlackGap (-0.10 pp) as of 2026-01-31. (1)
• U-6 underemployment and participation-adjusted unemployment data would improve reliability.
