Brazil's benchmark interest rate sits at 15% as of March 2026. That makes Tesouro Direto bonds some of the highest-yielding government debt on the planet. The problem? Buying them traditionally means opening a Brazilian brokerage account, getting a CPF tax ID, and navigating foreign exchange restrictions that most non-Brazilian investors won't bother with.

Tokenized versions of these bonds change the equation. They put Brazilian government-backed yields on-chain, accessible with a crypto wallet instead of a local brokerage. And they're growing fast.

Brazilian government bonds currently pay 13% to 15% annually, roughly triple the yield on tokenized US Treasuries. Tokenized versions from protocols like Etherfuse and Crown bring these yields on-chain, letting global investors access Tesouro Direto exposure without a Brazilian brokerage account or CPF tax ID. For investors already comfortable with tokenized US Treasuries yielding 4% to 5%, Brazilian bond tokens offer a significant step up in return, though they carry additional currency risk from BRL exposure. Compare underlying bond type, fee structure, and redemption terms before committing capital.

Key takeaways

• Tokenized Brazilian treasuries give global investors access to 13%+ government-backed yields without needing a Brazilian bank account.

• Selic rate at 15%: Brazil's benchmark rate is the highest since 2006, making its bonds among the most attractive sovereign debt globally.

• Growing market: Tokenized RWA protocols now hold over $17 billion in TVL, with treasuries as the largest subcategory.

• Key tradeoff: Higher yields come with BRL currency risk. If the real weakens against the dollar, returns shrink.

• Multiple options: Etherfuse (Solana), Crown's BRLV stablecoin, and Mercado Bitcoin's RFD products all offer different approaches to on-chain Brazilian bond exposure.

What is Tesouro Direto?

Tesouro Direto is Brazil's program for selling federal government bonds directly to individuals. Launched by the National Treasury in partnership with B3 (Brazil's stock exchange), it lets anyone invest in government debt starting from about R$30, which is roughly $5 to $6 USD.

Three main bond types are available:

For context, Brazil's 10-year government bond yield hovers around 13.5% to 14%. Compare that to the US 10-year at roughly 4.3%. The spread is enormous.

Why can't everyone just buy them?

Foreign investors face real barriers. To buy Tesouro Direto directly, you need a CPF (Cadastro de Pessoas Fisicas, Brazil's tax identification number), a brokerage account with a Brazilian institution, compliance with IOF tax rules on foreign capital inflows, and you take on BRL/USD conversion friction at every step.

That's a lot of paperwork for a bond purchase. Most international investors skip it entirely, which means they're leaving 13%+ government-backed yields on the table.

How do tokenized Brazilian treasuries work?

Tokenized versions wrap the underlying bonds into on-chain tokens. The issuer buys the actual government bonds, holds them in custody, and mints tokens that represent fractional ownership of the position. Yield accrues to the token, and holders can redeem for the underlying value.

The model is identical to how Ondo Finance and BlackRock's BUIDL fund tokenize US Treasuries. The difference is the underlying asset: Brazilian bonds yielding 13% instead of American bonds yielding 4.5%.

Here are the main protocols doing this today:

Etherfuse (TESOURO Stablebond)

Etherfuse builds on Solana and offers what they call "Stablebonds," tokens directly backed by sovereign government bonds. Their TESOURO token is backed by Brazilian government bonds that track the Selic rate.

• Current APY: approximately 13%

• Chain: Base

• Minimum: No high minimums, buy fractional positions

• Settlement: Bonds mature weekly, interest accrues daily

• Fees: Range from 0.25% for lower-yield bonds to 1.5% for high-yield bonds (10%+ APY)

• KYC: Required when buying directly. Accessible without KYC through aggregators like Pistachio.fi.

Crown (BRLV stablecoin)

Crown takes a different approach. They issue BRLV, a stablecoin pegged 1:1 to the Brazilian real and fully backed by government bonds. Co-founded by a former Brazil Central Bank official, Crown raised $13.5 million in a Series A in December 2025 from Paradigm, Coinbase Ventures, and Framework Ventures.

• Yield access: approximately 14% (reflects 10-year bond yields)

• Model: BRL-pegged stablecoin with reserve income shared with partners

• Scale: R$360 million (~$67 million) in committed funds as of December 2025

• Differentiator: Unlike USDT or USDC, where the issuer keeps all reserve yield, Crown shares it

Mercado Bitcoin (Renda Fixa Digital)

Brazil's largest crypto exchange, Mercado Bitcoin, offers tokenized fixed-income products through its Renda Fixa Digital (RFD) program. In 2025, they distributed R$1.8 billion (~$325 million) to users through these products, with average yields of 132% of CDI (the interbank rate that closely tracks Selic), effectively 13% to 15% annualized.

RFD volume more than doubled in 2025. Low-risk digital fixed-income products grew 108% that year alone.

How do they compare to tokenized US Treasuries?

The tokenized treasury market has exploded. Tokenized US Treasuries crossed $10.8 billion in market cap by late February 2026. BlackRock's BUIDL fund alone holds $18 billion across nine blockchain networks. But nearly all of that capital sits in US government debt yielding 4% to 5%.

The yield gap is hard to ignore. Brazilian bonds pay nearly three times what US bonds offer. The tradeoff is currency risk: if the BRL weakens 10% against the dollar in a year, your 13% yield shrinks to roughly 3% in USD terms. But if BRL holds steady or strengthens, you keep most of that yield premium.

For a crypto portfolio that already includes ETH staking at 3% to 4% and stablecoin lending at 5% to 8%, adding a slice of Brazilian government bond tokens at 13% creates meaningful diversification. You're earning sovereign-backed yield from a different economy, uncorrelated with DeFi protocol risk.

What are the risks?

Tokenized Brazilian treasuries are government-backed, but they aren't risk-free. Here's what to watch:

Currency risk is the big one. You're exposed to the BRL/USD exchange rate. Brazil's central bank held Selic at 15% partly because inflation has been stubborn. If the real depreciates faster than your yield accumulates, dollar-denominated returns suffer. Historically, the real has been volatile against the dollar.

Smart contract and custodial risk. The underlying bonds are safe (Brazil has never defaulted on domestic-currency debt), but the token wrapper adds layers. You're trusting the issuing protocol's smart contracts, their custodial arrangement, and their redemption process. These platforms are newer and smaller than BlackRock's BUIDL.

Liquidity. Tokenized US Treasuries have billions in liquidity. Tokenized Brazilian bonds have tens of millions. Exiting a large position quickly could mean slippage or waiting for redemption windows.

Regulatory uncertainty. Brazil's crypto regulatory framework is still evolving. The central bank abandoned blockchain technology for its Drex CBDC project in late 2025, pivoting it into a broader tokenization platform. CVM (Brazil's SEC equivalent) continues refining rules for tokenized securities through ongoing public consultations. The rules could change.

These risks are manageable for investors who size the position appropriately. A 5% to 15% allocation within a broader crypto yield portfolio captures the yield premium without overexposing to any single risk factor.

Platforms like Pistachio.fi help manage this kind of complexity. You can access Etherfuse TESOURO tokens without KYC, every vault comes with an expert risk grade, and curated vaults filter out the noise to surface protocols with proven track records. Zero gas fees mean your yield isn't eaten by transaction costs.

The bigger picture: why RWA yields are going on-chain

Tokenized Brazilian treasuries are part of a much larger shift. Real-world asset (RWA) protocols now hold over $17 billion in total value locked, up 210% in 2025 alone. RWA has overtaken DEXs to become the fifth-largest DeFi category by TVL.

The pattern is clear: sovereign debt is moving on-chain because the infrastructure finally supports it. BlackRock, Franklin Templeton, and WisdomTree have all launched tokenized treasury products. In February 2026, the SEC approved WisdomTree's plan for 24/7 trading of its tokenized money market fund. B3, Brazil's own stock exchange, announced plans to launch a tokenization platform and BRL stablecoin in the first half of 2026.

Until now, most of this activity focused on US Treasuries. Brazilian bonds are the logical next frontier because the yields are dramatically higher and Brazil is already the world's fifth-largest crypto market by adoption, according to Chainalysis. Transaction volume grew 43% in 2025, with about 20% of the population holding crypto.

For DeFi-native investors, these tokens also unlock composability. A tokenized Brazilian treasury bond can serve as collateral in lending protocols, margin for derivatives, or a building block in structured yield strategies. That's something a traditional Tesouro Direto bond sitting in a Brazilian brokerage account can never do.

How to get started with tokenized Brazilian treasuries

The process depends on which platform you choose:

1. Etherfuse TESOURO: Buy directly on Etherfuse (requires KYC) or access through Pistachio.fi without KYC. Yield accrues daily. Bonds mature weekly.

2. Crown BRLV: Access through partner platforms or directly (institutional focus for now, broader access expanding in 2026).

3. Mercado Bitcoin RFD: Primarily available to Brazilian residents through the MB platform.

Before you buy, check three things: the fee structure (Etherfuse charges 0.25% to 1.5% depending on yield tier), the redemption terms (how quickly can you exit?), and the custodial setup (who holds the underlying bonds and how are they audited?).

If you're building a diversified yield portfolio, Pistachio.fi gives you access to curated DeFi vaults alongside tokenized asset opportunities. Every option carries an expert risk grade, you pay zero gas fees, and treasury yield comparisons help you decide how to allocate between traditional and on-chain options. Built-in Awaken.Tax integration means one-click portfolio export when tax season arrives.

Frequently asked questions

Are tokenized Brazilian treasuries safe?

The underlying bonds are backed by the Brazilian government, which has never defaulted on domestic-currency debt. The main risks are BRL currency fluctuations, smart contract vulnerabilities in the token wrapper, and the relative newness of issuing platforms compared to established players like BlackRock. Size your position according to your risk tolerance.

How much yield can I earn from tokenized tesouros?

Current yields range from 13% to 15% annually, depending on the bond type and platform. Tesouro Selic-backed tokens track the benchmark rate of 15%. After platform fees (0.25% to 1.5%), net yields typically land around 13% to 14%. These are denominated in BRL, so USD-equivalent returns depend on exchange rate movements.

Do I need a Brazilian bank account to buy tokenized tesouros?

No. That's the entire point. Traditional Tesouro Direto requires a CPF tax ID and Brazilian brokerage account. Tokenized versions like Etherfuse TESOURO are accessible through Pistachio.fi without KYC, or directly on Etherfuse with KYC. Crown's BRLV is accessible through partner platforms without Brazilian banking infrastructure.

What is the difference between tokenized Brazilian and US treasuries?

The main difference is yield: Brazilian bonds pay 13% to 15% versus 4% to 5% for US Treasuries. Brazilian tokens are denominated in BRL, adding currency risk. US Treasury tokens (like BlackRock BUIDL or Ondo OUSG) have far deeper liquidity, with over $10 billion in market cap compared to tens of millions for Brazilian equivalents. US tokens are also available on more chains and through more platforms.

Will Brazilian treasury yields stay this high?

Market consensus expects Brazil's central bank to begin cutting the Selic rate in 2026, potentially bringing it from 15% to around 11.5% by year-end through a series of 50 basis point cuts. Even at 11.5%, Brazilian bonds would still yield more than double the current US Treasury rate. The high yields reflect Brazil's inflation environment and monetary policy stance, not credit distress.
