With this in mind, we have prepared an article with all the information you need to better understand how the profitability of Tesouro Direto works.

What is Tesouro Direto?
Tesouro Direto is a government program for issuing public sales bonds.
The process works in a similar way to loans.
To begin, you will choose a bond to invest in. In exchange, on the maturity date, you will receive an interest rate, which is the profitability of the Treasury Direct.
They are offered in three modalities:
1. Prefixed Treasury
The fixed-rate treasury is a fixed-income security with interest rates determined at the time of contracting.
This means that at the time of hiring, you will know exactly how much you will receive at the end of the period.
For this reason, fixed-income securities are recommended for the more conservative, who are looking for an asset that offers not only profitability, but predictability and security.
2. Selic Treasury
Tesouro Selic is the best-known form of Tesouro Direto.
It gets this name because its profitability is linked to Selic, the basic interest rate of our economy.
This option is recommended for those who are thinking in the short term or want to create an emergency reserve, as it has the lowest risk in the event of early redemption/sale.
Even so, the Selic Treasury It continues to be a good option for those who invest in the medium and long term, since the amount can be redeemed on the maturity date.
As we said, because this modality has its yield linked to the Selic rate, which can change every 45 days, its interest rate is post-fixed.
3. IPCA Treasury
The IPCA Treasury is a public security whose profitability is linked to the main inflation index in Brazil, the IPCA – Broad National Consumer Price Index.
It is a hybrid security. In other words, part of its remuneration is post-fixed, since it follows the variation of the IPCA, and the other part is prefixed.
The post-fixed rate will vary throughout the investment, adjusted based on the IPCA, which varies month to month.
Regarding the fixed rate, at the time the title is purchased, you will already know how much you will receive, because as the name suggests, the fixed rate will not change.
