Credit Spreads Signal

Signal Summary:

• Configuration statement: Given HY_OAS at 2.78% and IG_OAS at 0.75%, this setup aligns with Upward-biased price paths and Compressed volatility, where the dominant risk is Trend continuation, not Regime shift (1).
• The signal reflects a persistent environment of low perceived default risk and abundant credit availability (1).
• Conviction Band: Low; Interpretation Confidence: Low Confidence; Internal Conflict Flag: Yes. Signal Stability Assessment: Stable; Threshold Proximity: Moderate; Revision Sensitivity: Moderate.

Methodology Applied:

• HY levels below 3.5% define a regime of low default risk and favorable conditions for equities (1).
• Regime upgrades require 2-period persistence or level/momentum agreement to filter microstructure noise (1).
• Standardised z-scores (CSC_z) between -0.5 and 0.5 define a neutral credit environment (1).
• Credit Spreads Signal (last observation: 2026-05-31) (1).

Key Dynamics:

• The primary driver is the HY_OAS level (2.78%), which sits significantly below the 3.5% "Risk-on" threshold (1).
• Spreads have stabilised at low levels after a period of volatility in early 2025 (1).
• Internal Tension: The absence of CSC z-score data prevents full composite regime verification (1).
• Conditional Invalidation: HY_OAS rising more than 50 bps within a 3-month window (1).
• Persistence: HY spreads have remained below the 3.5% threshold for three consecutive months (1).

Scenario Balance:

• Base Case dominant: Abundant liquidity supports continued risk-asset expansion.
• Upside secondary: Further spread compression if IG momentum accelerates downward.
• Downside residual: Systemic shock propagation if credit-specific deterioration causes a rapid spike in OAS.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months), reflecting broader corporate funding and default cycles (1).
• Aggregation Weight Hint: Low, due to missing composite score metrics required for high-conviction macro-aggregation.

Macro Relevance:

• Informs the financial system stability and market-wide risk appetite dimensions (1).
• Implied Mechanism: Low spreads reduce corporate funding stress, supporting capex and profitability (1).
• Cycle position: not determined.
• Interaction: Typically used to validate VIX levels; divergence signals early credit-specific stress (1).

Regime Context:

• The current low-spread regime has been persistent since March 2026 (1).
• Direction of change: Stabilising at historical lows.

Model Limitations:

• 1-2 day reporting lags and vendor revisions can impact signal accuracy (1).
• Bid-ask spread inflation during liquidity shocks can cause false regime flips (1).
