About Moody's Seasoned Aaa Corporate Bond Yield
What it measures
The Moody's Aaa corporate bond yield (FRED series WAAA) is the weekly average yield on seasoned corporate bonds rated Aaa by Moody's, drawn from long-maturity issues of the highest-quality US companies. The series extends back to 1919, making it one of the longest continuous records of top-grade corporate borrowing costs available.
Why it matters
The Aaa yield shows what the strongest corporations pay for long-term debt, effectively the private-sector floor on borrowing costs. Its spread over long Treasuries isolates the premium for even minimal credit risk plus liquidity differences. The century-long history makes it invaluable for studying rate cycles, and it feeds into cost-of-capital and pension discount rate calculations.
How to read it
Moves largely track long-term Treasury yields, since default risk at this rating tier is negligible; widening of the spread over Treasuries typically signals liquidity strain rather than solvency fears. The pool of Aaa-rated issuers has shrunk to a handful of companies, so the index rests on few names. Levels have ranged from around two percent to the mid-teens across the past century.
