Most investors still compare fixed income by looking only at the interest rate. And that’s exactly why they’re leaving money on the table.
With asset tokenization projected to reach R$7 billion in volume in the digital fixed income segment this year, the question is no longer “does this exist?”, but rather: “what really changes in the structure and return when we move from the traditional banking model to a digitized model with fewer intermediaries?”
The answer lies not only in profitability. It lies in the architecture of the operation. And understanding this difference is what separates those who make well-informed decisions from those who merely compare rates on a spreadsheet.
In this article, we explore the structural differences between the two models, from the functioning of bank intermediation to the logic of issuing digital instruments, and why the superior return of digital fixed income is not an accident, but a direct consequence of more efficient engineering.
What is fixed-income banking?
Bank fixed income is the most established model for raising capital and investing in Brazil.
In this model, the bank acts as a central intermediary: it raises funds from investors, remunerates these funds at an agreed rate, and allocates the capital raised to credit operations for companies or individuals.
It is a robust system, with decades of operation, a consolidated regulatory structure, and broad reach. But its operational efficiency has clear limits, and these limits are directly linked to the logic of the bank spread.
How does bank intermediation work in fixed income investments?
In the traditional model, a bank functions as a transformer of terms and risks. It raises funds from many investors for short terms and lends to borrowers for longer terms, assuming the credit risk in that interval.
To do this profitably, you need to include a margin, the spread, between what you pay the investor and what you charge the borrower.
This spread is not just profit. It covers operational costs, regulatory reserves (such as the reserve requirement), compliance structure, default risk, and the maintenance of the entire institutional chain involved in the operation.
The practical result is that the investor receives a portion of the return generated by the loan, not the majority.
Furthermore, the bank standardizes risk. It groups transactions into categories and sets rates based on average profiles, meaning that good transactions often subsidize riskier transactions within the same portfolio.
What are the main fixed-income bank products?
The most common fixed-income banking instruments in Brazil include:
- CDB (Bank Deposit Certificate): a security issued by a bank to raise funds from investors, with returns generally linked to the CDI (Interbank Deposit Certificate) rate;
- LCI (Real Estate Credit Bill) and LCA (Agribusiness Credit Bill): fundraising with sector-specific backing and income tax exemption for individuals;
- Savings account: the most popular product, with regulated returns and low relative profitability;
- LC (Letra de Câmbio): issued by finance companies, with a slightly different risk profile than traditional banks.
All these instruments are covered by the FGC (Credit Guarantee Fund) up to the established limits, which represents an additional layer of protection, but also a systemic cost that influences the rates paid to the investor.
What is digital fixed income?
Digital fixed income is not a subcategory of bank fixed income.
It is a different architecture for structuring and distributing credit, which uses technology, especially asset tokenization infrastructure, to bring issuers and investors closer together, reduce intermediaries, and make processes more efficient, traceable, and agile.
In the digital model, a company that needs to raise capital can structure a private credit operation and distribute it directly to qualified investors, with defined collateral, clear governance, and a robust legal basis, without necessarily going through a bank’s balance sheet.
What instruments are part of digital fixed income?
The digital fixed income ecosystem is composed of capital market instruments that already existed legally, but which are now gaining operational efficiency with digital infrastructure. Among the main ones are:
- Commercial Note: a fundraising instrument for companies, with an average return of around 20.31% per year according to data from structured operations in the market in 2026;
- Debentures: corporate debt securities, with an average return of approximately 18.12% per year;
- CCB (Bank Credit Certificate): a credit instrument with traceability and a solid contractual basis;
- CRI (Real Estate Receivables Certificate): backed by real estate sector transactions, with an average return of around 22.06% per year;
- CRA (Agribusiness Receivables Certificate): backed by agribusiness transactions, with average returns of 17.44% per year;
- Structured and tokenized loans: structured operations based on companies’ receivables streams, with an average return of 15.08% per year.
The benchmark CDI rate in 2026 is 14.73% per year. All the instruments mentioned above, when well-structured, deliver a premium over this base, and the difference in return is directly related to how efficient the operation’s structure is.
How does digital fixed income differ from crypto and speculative assets?
This is a fundamental and often misunderstood distinction. Digital fixed income operates with assets backed by real transactions, corporate credit, receivables, real estate, and agricultural contracts. It is not speculation on market appreciation.
Unlike cryptocurrencies, whose returns depend on supply and demand dynamics and are not backed by a tangible underlying asset, digital fixed income instruments have predictable cash flow, a defined legal structure, and issuance responsibility linked to regulated agents.
Vale notar: os dados de rentabilidade de criptoativos, como o retorno médio de 20,87% ao ano citado em comparações de mercado, referem-se a um período específico e não representam previsibilidade de retorno, o oposto do que define a renda fixa como classe de ativo.

Digital vs. Bank Fixed Income: Structural Differences
Comparing digital and bank fixed income investments solely based on profitability is like comparing two engineering projects solely based on their final price.
What truly differentiates the models lies in the architecture of the operation, and understanding this difference helps to more accurately assess where the risks and opportunities are.
| Aspect | Bank Fixed Income | Digital Fixed Income |
| Intermediation | High — the bank acts as a central hub between borrower and investor, absorbing the spread at each layer. | Low direct structuring between issuer and investor, with less operational friction. |
| Transparency of collateral | Low — the investor trusts the institution’s solidity, without traceability of the capital’s destination | High — when well-structured, the collateral is part of the operation’s engineering and traceable in real time |
| Pricing | Opaque — rate defined by average risk profile; good operations often subsidize the riskier ones. | Based on the operation — rate reflects the real quality of the credit, the collateral, and the governance of the issuance. |
| Return to investor | Limited by the bank spread — the investor receives part of the generated return, not the majority | Potentially higher — premium over the CDI possible due to the efficiency of the structure, not necessarily due to additional risk |
| Access | Mass-market product — standardized for the retail market, without customization per operation | Expanded — medium-sized companies and originators can access the capital market more quickly |
| Operational efficiency | High standardization, low customization — robust model, but with clear structural limitations | Customizable by operation — structuring can be adapted to the asset, the issuer, and the distribution profile |
| Investor protection | FGC up to established limits — a consolidated protection layer, but with embedded systemic costs | |
| Regulation | CVM and Central Bank — consolidated framework widely known by the market | CVM and Central Bank — same regulators, instruments with their own regulation (CRI, CRA, NC, Debentures, CCB) |
Does digital fixed income eliminate intermediaries? Understand the impact on returns.
In the banking model, the chain between the borrower and the final investor passes through the bank’s balance sheet, the risk area, the funding structure, compliance, and the operational cost of this entire machine.
Each layer has a cost, and that cost comes from the spread, which reduces the investor’s return.
In digital fixed income, the structure is more straightforward. A credit originator, an independent structurer, or an issuing company can access the capital market with the support of a regulated technological infrastructure, such as that offered by BLOCKBR, without needing a bank balance sheet as an intermediary.
The result is a shorter chain, with less friction and more efficient distribution of returns between the parties.
Operations that previously took months to structure can now be completed in weeks, which directly impacts the total cost of the operation and, consequently, the rate the investor receives.
Difference in transparency of collateral and pricing.
In the banking model, the investor who buys a CDB (Certificate of Deposit) doesn’t know exactly where the money is going.
He trusts in the bank’s solidity, and that trust has been built over decades, reinforced by regulation and the FGC (Credit Guarantee Fund). But traceability of the collateral is not a feature of the product.
In well-structured digital fixed income, the underlying asset is part of the operation’s engineering.
Each instrument must be linked to identifiable real assets, receivables, contracts, real estate, and tokenization enables the registration and traceability of this underlying asset in real time. This allows the investor to assess the quality of the underlying asset, not just the rating of the issuing institution.
This transparency, however, only exists when the operation is properly structured.
Operations with weak backing or deficient governance may use digital infrastructure without offering any of the real advantages that the model allows.
Difference in access and operational efficiency
Historically, the Brazilian capital market was accessible only to large companies capable of bearing the costs of structuring a public offering. The process involved multiple intermediaries, lengthy regulatory timelines, and high minimum volumes.
Digital infrastructure significantly reduces these costs. Medium-sized companies, credit originators, and issuers from different sectors can now access the digital capital market with greater agility, more control over the structure of their operations, and less dependence on centralized agents.
This increase in operational efficiency is one of the factors that makes it possible to offer superior returns to the investor without necessarily increasing the risk of the operation.
Why can digital fixed income deliver superior returns?
The straightforward answer is: because the operation absorbs fewer intermediary costs. But that’s not the whole story.
The straightforward answer is: because the operation absorbs fewer intermediate costs. But that’s not the whole story.
- Issuer credit quality: the actual ability of the issuing company or structure to pay;
- Consistency of collateral: existence and traceability of assets that guarantee the operation;
- Structure of guarantees: what happens to the investor in case of default and what is the recovery mechanism;
- Governance of the operation: who is behind the issuance, what is the role of each agent, and how is the contract legally structured.
A well-structured operation can offer a real premium over the CDI (Brazilian interbank deposit rate) without proportionally increasing risk, because part of that premium comes from efficiency, not from taking on additional risk. A poorly structured operation can offer the same rate and hide risks that the investor cannot adequately assess.
This is precisely where the quality of the infrastructure makes a difference.
BLOCKBR, as an asset tokenization infrastructure for the regulated financial market, acts in structuring these operations by integrating legal, technology, compliance, and financial aspects, not as an issuer of its own products, but as the operating system that allows third parties to create and operate digital assets within the regulated market with the necessary governance to ensure a meaningful return.

The scenario of pressure on private credit funds in the US in 2026 reinforces, moreover, that structural efficiency and collateral quality are not unique to Brazil; they are determining variables in any maturing private credit market.
Is digital fixed income regulated in Brazil?
Yes, and this is a point that needs to be stated clearly, because there is a lot of confusion about the topic.
Digital fixed income instruments operate within the Brazilian regulatory framework, under the supervision of the CVM (Securities and Exchange Commission) and the Central Bank, depending on the type of asset and the structure of the transaction.
Commercial notes, debentures, CRI (Real Estate Receivables Certificates), and CRA (Agribusiness Receivables Certificates), for example, are instruments that already have consolidated regulations. What changes with the digital infrastructure is the operational efficiency of issuance and distribution, not the regulatory framework.
A tokenized transaction follows the same legal rules as its traditional counterpart in the capital markets.
What solutions like BLOCKBR Station enable in this context is the integration between these instruments and the regulated agents necessary for the operation, such as securities brokers, custody, fiduciary structures, central depository, and registries.
This institutional layer is what ensures that a digital operation is not only technologically efficient, but also legally valid and operationally traceable.
For those evaluating whether digital fixed income is worthwhile, the answer depends less on the instrument itself and more on the quality of who structured the operation and whether the entire regulatory chain was respected.
Well-constructed infrastructure is not an operational detail; it’s what separates a good opportunity from a poorly priced risk.
The digital fixed income market in Brazil is currently undergoing a real consolidation phase. The relevant question isn’t whether it will grow; the numbers indicate that it will.
The question is: who will be on the right side of the structure when this growth materializes?
