Credit Spreads Signal

Signal Summary:

• Configuration statement: Given a HY_OAS of 3.27, a CSC_z of 0.08, and accelerating 3-month momentum (1.27), 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 NORMAL regime, reflecting credit conditions aligned with historical averages (1).
• Conviction Band: Medium; Interpretation Confidence: High Confidence; Internal Conflict Flag: No. Signal Stability Assessment: Deteriorating; Threshold Proximity: Near; Revision Sensitivity: Unknown.

Methodology Applied:

• A NORMAL regime is defined by High Yield (HY) spreads between 3.5% and 5% or a CSC z-score between -0.5 and 0.5 (1).
• The TIGHTENING regime is triggered if HY spreads rise >50bps in 3 months or the CSC z-score reaches ≥0.5 (1).
• Rising values imply a risk-off transition, tightening financial conditions, and an economic slowdown (1).
• Credit Spreads Signal, latest observation: 2026-03-31 (1).

Key Dynamics:

• The primary driver is the 3-month annualized momentum in HY spreads (z-score 1.27), indicating rapid widening from recent lows (1).
• Momentum has shifted from negative in early 2025 to consistently positive over the last quarter (1).
• Internal Tension: While HY spreads are widening, Investment Grade (IG) spreads remain more suppressed (z-score -0.55), suggesting stress is currently concentrated in lower-tier credit (1).
• Conditional Invalidation: An HY spread increase exceeding 50bps over 3 months would force a transition to a Tightening regime (current 3m change is +46bps) (1).

Scenario Balance:

• Base Case dominant: Continued range-bound Normal regime as spreads mean-revert toward historical averages.
• Upside risk: Transition to EASY regime if HY spreads fall below 3.5% and CSC_z drops below -0.5.
• Downside risk: Shift to TIGHTENING if current widening momentum persists, breaching the 50bps 3-month threshold.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months); captures shifts in default expectations and liquidity premia.
• Aggregation Weight Hint: Medium; provides a critical check on equity risk appetite and funding availability.

Macro Relevance:

• This signal informs the US Credit Conditions macro dimension by measuring the cost of corporate borrowing relative to risk-free rates (1).
• The economic mechanism is liquidity premia and default risk; rising spreads signal increased funding costs for cyclical firms (1).
• Cycle position: Not determined.
• Interaction: Typically confirms VIX movements; widening spreads with a calm VIX would signal credit-specific deterioration (1).

Regime Context:

• The NORMAL regime has been persistent for five consecutive months following a brief EASY phase (1).
• Direction of change: Strengthening/Deteriorating (spreads are moving from the bottom of the "Normal" range toward the "Tightening" threshold).

Model Limitations:

• Suffers from a 1-2 business day reporting lag and frequent vendor revisions (1).
• Bid-ask spread widening during market shocks can artificially inflate levels, creating microstructure noise (1).

• HY_OAS (3.27) and hy_d3m_ann_z (1.27) are the most influential current datapoints (1).
