# Credit Methodology

> Credit Benchmark collects, processes, and publishes consensus credit ratings from PD estimates submitted by the world's leading financial institutions.

Credit Benchmark collects **1-year through-the-cycle (TTC) Probability of Default (PD)** estimates from over 40 of the world's leading financial institutions and aggregates them into consensus credit analytics — published weekly at the entity and portfolio level.

Contributions are governed, validated, and processed through a defined pipeline before publication. Individual bank views remain completely confidential.
