What is Tesouro IPCA and Why Does It Attract So Much Interest?
If you’ve researched fixed-income investments in Brazil, you’ve likely encountered the name Tesouro IPCA+. It’s one of the most popular federal public bonds among investors looking to protect their money from inflation over time. But what exactly does “IPCA-linked profitability” mean? How does this bond work in practice, how much does it yield, and what are the risks involved?
In this article, we will explore Tesouro IPCA+ clearly and objectively, explaining the product’s mechanics, its taxation, real advantages, and the points of attention every investor needs to know before applying. The goal is educational: by the end of the reading, you will have the necessary knowledge to assess whether this type of asset deserves a place in your strategy — and you will know exactly where to look for updated information before making any decision.
It is worth remembering from the outset: all investments involve risks, and market conditions change. Numbers like interest rates and returns vary constantly, so we will guide you to always check the most recent data from official sources.
What is Tesouro IPCA+?
The Tesouro IPCA+ is a federal public bond issued by the Brazilian government and traded on the Tesouro Direto platform, managed by the National Treasury in partnership with B3. By purchasing this bond, you are essentially lending money to the federal government and receiving back the value adjusted for inflation plus a pre-fixed real interest rate.
The profitability of Tesouro IPCA+ consists of two parts:
- IPCA: the Extended National Consumer Price Index, measured monthly by IBGE, which represents Brazil’s official inflation.
- Pre-fixed real rate: an additional percentage defined at the time of purchase, representing your gain above inflation.
When you see an offer like “IPCA + X% per year,” it means that, at the end of the period, your money will have been adjusted for accumulated inflation plus that real interest rate. This ensures, in theory, that your purchasing power is preserved and even grows in real terms — as long as the bond is held until maturity.

The Two Modalities: With and Without Semiannual Interest
There are two versions of Tesouro IPCA+:
Tesouro IPCA+ (without coupon)
In this version, interest is accumulated and paid only at the bond’s maturity, along with the value adjusted by the IPCA. It is suitable for those who do not need income during the period and wish to reinvest earnings automatically, taking advantage of the compound interest effect.
Tesouro IPCA+ with Semiannual Interest
In this modality, the investor receives interest payments every six months — the so-called semiannual coupons. At the end, they also receive the face value adjusted for inflation. It is an interesting alternative for those who want to use the earnings as supplementary income over time — such as retirees or people in the asset enjoyment phase.
The main practical difference, besides the cash flow, is in taxation: each semiannual coupon payment is individually taxed by Income Tax, which may reduce the efficiency of compound reinvestment.
How Mark-to-Market Works
This is one of the most important — and least understood — aspects of Tesouro IPCA+.
Public bonds have their price updated daily in the market, in a process called mark-to-market. This means that if you need to sell the bond before maturity, the amount you will receive may be higher or lower than expected, depending on market conditions at that time.
How does this happen? When market interest rates rise, the price of long-term fixed-income bonds tends to fall. When rates fall, the price tends to rise. This occurs because the market recalibrates the present value of the bond’s future cash flows.
In practice:
- If you buy a Tesouro IPCA+ and hold it until maturity, you will receive exactly the accumulated IPCA plus the real rate agreed upon at the time of purchase — without surprises.
- If you need to sell before maturity, the redeemed value will be the market price on that day, which may represent a gain or loss compared to what you paid.
Therefore, Tesouro IPCA+ is a suitable bond for medium and long-term goals, where there is a good probability of maintaining the investment until the maturity date.
Taxation: What You Need to Know
Tesouro IPCA+ follows the same tax rules as other fixed-income bonds in Brazil, according to the Federal Revenue’s regressive Income Tax table:
Investment Term IR Rate Up to 180 days 22.5% From 181 to 360 days 20% From 361 to 720 days 17.5% Over 720 days 15% The IR is levied only on earnings, not on the principal amount applied. The tax is withheld at the source at the time of redemption or receipt of semiannual coupons.
In addition to the IR, there is the incidence of IOF (Tax on Financial Operations) for redemptions made within the first 30 days of application, following a regressive table that zeros on the 30th day.
There is also the custody fee charged by B3: check the current percentage directly on the Tesouro Direto website or the B3 portal, as this value can be updated periodically. Some brokers charge additional administration fees, but many offer the product without their own fee — it’s worth comparing before choosing where to invest.

Advantages and Risks: A Balanced View
Advantages
- Inflation Protection: adjustment by the IPCA preserves purchasing power over time, something that pre-fixed investments or savings do not always guarantee in high inflation scenarios.
- Federal Government Guarantee: public bonds are issued by the National Treasury, representing the lowest credit risk available in the Brazilian domestic market.
- Accessibility: it is possible to start investing with low amounts, democratizing access to this type of instrument.
- Transparency: conditions are known at the time of purchase — the investor knows exactly what real rate they will receive if held until maturity.
- Daily Liquidity: the National Treasury offers daily repurchase of bonds, ensuring that the investor can exit the investment if necessary (observing mark-to-market).
Risks and Disadvantages
- Market Risk (mark-to-market): as explained, selling before maturity can result in losses, especially in periods of rising interest rates.
- Reinvestment Risk: in bonds with semiannual coupons, the amounts received need to be reapplied by the investor, and the rate available in the future may differ from the original.
- Taxation on Coupons: semiannual receipts are individually taxed, reducing the efficiency of compound interest compared to the bond without a coupon.
- Underestimated Inflation: the IPCA is the official indexer but may not perfectly reflect the price variation of your personal consumption profile.
- Long Term: many Tesouro IPCA+ maturities extend for decades. Immobilizing resources for such a long time requires planning and certainty about objectives.

Conclusion: Who is Tesouro IPCA+ Suitable For?
Tesouro IPCA+ is a valuable instrument for those who wish to protect the purchasing power of their assets over many years. It is especially relevant for long-term goals, such as retirement, children’s education, or wealth building, precisely because time plays in favor of the investor — both through the accumulation of compound interest and the dilution of market risk.
However, it is not a magic solution nor free from risks. Those who might need the money before maturity, have short-term goals, or have no tolerance for portfolio value fluctuations should carefully evaluate whether this is the right instrument for their moment.
The most important thing is to make decisions based on information, clear objectives, and your financial reality — not on promises of returns or market trends. Always check current conditions from official sources before investing.
