Marketable Treasury debt maturity profile + WAM

Changed on

The maturity structure of the outstanding marketable US Treasury debt for the latest monthly MSPD snapshot: the weighted-average maturity (WAM, weighted by each security's outstanding amount), the outstanding split across maturity buckets (<1y, 1-3y, 3-5y, 5-10y, 10-20y, 20y+), and a by-class breakdown (Bills / Notes / Bonds ...) with each class's own WAM. Amounts are in USD millions. Computed per-security from MSPD table 3 (monthly cadence). Source: US Treasury Fiscal Data (CC0).
