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).

Coverage

111 companies with CDS spread data
~53,000 records across all tenors and dates
598 trading days (March 2023 to present)
5 tenors: 1Y, 3Y, 5Y, 7Y, 10Y
Updated daily at 9:30 PM ET

Methodology

Spreads are computed using a bond spread-to-treasury proxy:

Select fixed-rate senior unsecured bonds with TRACE pricing
Group by remaining maturity into tenor buckets (1Y / 3Y / 5Y / 7Y / 10Y)
Apply data quality filters (price >= $60, no estimated pricing, maturity >= 1 year)
Remove outliers (3-sigma for groups >= 4 bonds, range check for smaller groups)
Report median spread-to-treasury in basis points

Negative spreads are possible for premium investment grade issuers (floor: -200 bps).
