Tesouro IPCA+ Yield

Tesouro IPCA+ (NTN-B): inflation-linked Brazilian bonds

Tesouro IPCA+ (technically NTN-B, Nota do Tesouro Nacional – Série B) is the Brazilian government’s inflation-linked bond. It pays a real rate fixed at purchase plus the IPCA (Brazil’s official consumer price index, calculated by IBGE) accumulated over the period. The nominal accumulated return is (1 + i_real)^n × (1 + IPCA)^n − 1, while the real return is just (1 + i_real)^n − 1 — guaranteed purchasing power above inflation if held to maturity.

There are two variants on Tesouro Direto: Tesouro IPCA+ Principal (NTN-B Principal, no semiannual coupons — principal and inflation accrue and are paid only at maturity, ideal for accumulation phase) and Tesouro IPCA+ with Semiannual Interest (NTN-B with cupons every 6 months at 6% a.a. on the inflation-adjusted principal, suited for income generation). Both are marked-to-market daily, so selling early exposes you to interest-rate risk; holding to maturity locks in the contracted real rate.

Applications

IPCA+ bonds are the gold standard for long-term goals tied to purchasing power: retirement planning, child education, real-estate down payments years ahead. They are also used by pension funds and family offices as the “safe asset” for liability-matching, and by individuals as a hedge against unexpected inflation. Monthly contributions can be automated via Tesouro Direto programs; coupons received can be reinvested in the same NTN-B at prevailing real rates.

FAQ

What is the difference between real and nominal return? Real return measures purchasing power gain above inflation; nominal return is the headline number including inflation. With IPCA at 4% and real rate at 6%, the nominal return per year is roughly 10.24% (compounded), but only 6% above inflation.

Can I lose money on IPCA+? Yes, if you sell before maturity and the market real rate rose since purchase, the bond’s PU dropped and you book a loss. Holding to maturity always delivers the contracted real rate plus IPCA. The longer the duration, the higher the mark-to-market volatility.

Is IPCA reliable? IPCA is calculated monthly by IBGE (Instituto Brasileiro de Geografia e Estatística) and is the official inflation index targeted by the Central Bank. It is independent, transparent, and widely audited — the benchmark used in the Treasury indexation.
