Macro comum

Definição. Indicative bond yields for LTN/NTN-F (nominal) and NTN-B (IPCA real), by security code, maturity and issue/base date.

Cobertura. Brazil federal government bonds; sample latest available date, refresh up to five weekdays in last seven calendar days.

Limitações. ANBIMA is the original quote producer, not a government statistical publisher. Public access is limited to five business days. Not a fitted zero-coupon curve, executed trade, risk-free rate selection or investment recommendation. LFT spread and NTN-C IGP-M yield remain in raw data and are intentionally excluded from normalized nominal/IPCA observations. No Tesouro retail-price fallback: it is a different quote perimeter, and its CSV downloads full history. Required coverage is all three bond families per returned date. Individual security memberships are publisher-dynamic, preserved in series_dimensions; this package cannot prove a missing maturity not present in a published file and does not claim a complete zero curve.
