​
Overview

Get CDS spread time series for corporate issuers. Spreads are derived from TRACE bond pricing data using a bond spread-to-treasury methodology, economically equivalent to CDS spreads (CDS-bond basis is typically within 20 bps for investment grade).

​
Methodology

Spreads are computed using a bond spread-to-treasury proxy:
  1. Select fixed-rate senior unsecured bonds with TRACE pricing
  2. Group by remaining maturity into tenor buckets (1Y / 3Y / 5Y / 7Y / 10Y)
  3. Apply data quality filters (price >= $60, no estimated pricing, maturity >= 1 year)
  4. Remove outliers (3-sigma for groups >= 4 bonds, range check for smaller groups)
  5. Report median spread-to-treasury in basis points
Negative spreads are possible for premium investment grade issuers (floor: -200 bps).
