About
Yield Book is a fixed-income analytics platform used by institutional investors, issuers, and dealers for mortgage and securitized product analysis. The platform originated within Citigroup and now operates within LSEG Data & Analytics.
Its core product surfaces include Yield Book Structuring Tool, Yield Book API, Yield Book Add-In, and Yield Book Calculator workflows for agency and non-agency mortgage sectors. Coverage supports structuring, valuation, scenario analysis, and relative-value research across major securitized asset classes.
API access is licensed and institution-controlled, with delivery patterns oriented to client implementations rather than anonymous open public endpoints. This makes Yield Book a common fit for firms that need production-grade analytics under enterprise data governance.
