Tesouro Direto Guide: Brazil's Best Government Bonds at Selic 14.75%

On March 18, 2026, Brazil's central bank cut the Selic rate from 15% to 14.75% — the first reduction since May 2024. The market projects the rate reaching 12.5% per year by the end of 2026, with gradual cuts at each Copom meeting. This trajectory changes the calculus for investors in Brazil's Tesouro Direto program.

Tesouro Direto is the federal government program that allows individual investors to purchase government bonds directly, through a brokerage. It is the safest fixed-income instrument available in the Brazilian market — and at Selic 14.75%, real returns are still meaningful.

The Three Main Bond Types

Tesouro Direto offers three primary bond categories:

Tesouro Selic: pays the accumulated Selic rate. The lowest-risk, highest-liquidity option — can be sold at any time without meaningful loss of value. Recommended for emergency reserves and short-term allocations.

Tesouro Prefixado: pays a fixed interest rate determined at the time of purchase. The investor knows exactly how much they will receive at maturity — as long as they do not sell early. Early sale means market pricing (mark-to-market), which can represent a gain or a loss.

Tesouro IPCA+: pays the variation of Brazil's official inflation index (IPCA) plus a pre-set fixed rate. Guarantees positive real return regardless of inflation. Also subject to mark-to-market if sold before maturity.

What Major Institutions Recommend

XP's Tesouro Selic 2029 and Itaú BBA's Tesouro Selic 2031 differ in term but share the same logic: in a gradual Selic-cutting environment, maintaining a position in a rate-tracking bond still captures the elevated rate differential for longer.

The Real Return of Tesouro Selic Today

At Selic 14.75%, Tesouro Selic delivers approximately 14.45% per year (after the B3 custody fee of 0.20% annually and the small Selic-CDI spread).

Discounting the projected IPCA for 2026 (market estimates around 6.5% to 7% per year), the real return of Tesouro Selic is approximately 7.06% per year. This is historically rare: it is uncommon for the safest fixed-income instrument in a market to deliver such high real returns.

After income tax (15% for applications held over 720 days), the real return falls to approximately 5.5% per year — still positive and meaningful by any historical metric.

Why IPCA+ Bonds Are Gaining Relevance

The logic of Tesouro Selic is to capture the current high rate. The problem: as the central bank cuts rates, Tesouro Selic's yield automatically falls. Someone buying Tesouro Selic today will receive 14.75% while Selic is at 14.75%, but will receive 12.5% when Selic reaches 12.5%.

Tesouro IPCA+ solves this problem for long horizons: you buy a bond paying IPCA + 6.5% (for example) and that fixed rate does not change — even if Selic falls to 10%. Real return is guaranteed regardless of the monetary policy cycle.

The downside of IPCA+ is mark-to-market: if you need to sell before maturity and interest rates have risen since purchase, you may incur a loss. For this reason, IPCA+ should only be purchased by investors certain they can hold to maturity.

Tesouro Prefixado: For Those Who Believe in Faster Cuts

Tesouro Prefixado is attractive for investors who believe Selic will fall faster than the market projects. The logic: if you buy a bond paying 13% per year and Selic falls to 10%, the market value of your bond rises (because it pays more than the current rate). This generates capital gain.

The risk is the inverse: if inflation surprises and the central bank pauses cuts or raises rates, Prefixado's market value falls, generating a loss for anyone who needs to exit before maturity.

Tax Treatment in Tesouro Direto

All Tesouro Direto bonds are taxed under Brazil's regressive income tax table:

Holding for more than 2 years reduces the tax rate on income from 22.5% to 15%. For long-term applications, the tax benefit is meaningful.

IOF (financial operations tax) applies in the first 30 days: early redemption before 30 days incurs both IOF and income tax. After 30 days, only income tax applies.

Practical Strategy by Investor Profile

The most defensive and broadly recommended strategy for the current environment is a combination of Tesouro Selic (for liquidity) with medium-to-long term IPCA+ (to guarantee future real returns). This captures the high current rate without sacrificing protection against future rate declines.

The Rate Cycle Reality

Investors need to think about timing carefully. The first Selic cut in 15 months happened in March 2026. If cuts proceed as projected (reaching 12.5% by year-end), someone who allocates entirely to Tesouro Selic will see their yield compress by 225 basis points over 9 months.

Someone who allocates even a portion to IPCA+ bonds at current rates of approximately 6.5% real per year is locking in a return that would remain attractive even in a 10% Selic environment. That optionality has real value in a declining rate cycle.
