Open Finance Brasil, the system in which customers authorize one financial institution to see the data they hold at another, reached 240 million consents, up 54%, according to an Exame report of August 31, 2026. The same report brought a warning: a study by Zetta showed that 61.5% of queries to the system's APIs return data that has not changed.
What happened
Open Finance was born as Open Banking and was rolled out in Brazil in phases. Phase 2, which began on August 13, 2021, put into operation the sharing of customer data between institutions, always with the customer's authorization. Phase 3, scheduled to start on August 30, 2021, brought payment services into the system. Phase 4, from December 15, 2021, expanded sharing to other financial products and services.
Five years later, the system has scale. Each consent is an authorization given by a customer for one institution to see or move data held at another, for a defined period and purpose. The 240 million consents show that the idea has left the drawing board.
The Zetta study, cited by Exame, looked at the other side. When 61.5% of API queries bring back exactly the same information, much of the system's traffic is repetition: institutions asking again for something they already knew. This costs processing, infrastructure and money for those who keep the APIs running.
In 2026, Open Finance also got a rule change. BCB Normative Instruction 746, of June 16, 2026, removed the fixed R$ 500 cap from the Open Finance journey without redirection, the same rule that applied to contactless Pix. Since October 1, 2026, each institution sets its customer's limit.
Why it matters
For decades, a person's financial history was stuck at the bank where they held an account. Anyone wanting credit elsewhere started from zero. Open Finance changes this logic: the data belongs to the customer, who decides whom to share it with. This can mean cheaper credit, better-suited offers and less paperwork.
The waste pointed out by Zetta shows that the system still needs to mature. If most queries are repeated, there is room for rules and technologies that signal when something has changed, instead of forcing each institution to ask all the time. A more efficient system costs less and can reach more people.
The end of the R$ 500 cap on the journey without redirection brings Open Finance closer to everyday use. Payments initiated from within another app, without jumping from screen to screen, can now also be used for larger amounts, according to each customer's profile.
In Bairo's view
Bairo Leandro Gonzalez Martinez reads Open Finance as a win for those who were always left outside. For him, the grower who sells every week at a wholesale supply center has a real financial history, but it rarely reaches those who decide on credit. In his reading, when the data belongs to the customer, that history can finally travel with them.
For Bairo, the 61.5% of repeated queries are a design lesson. Infrastructure that connects those who were left out must be light, with the least possible friction, from grower to buyer. In his view, asking the same thing a thousand times is the opposite of that: it is a cost someone pays at the end of the chain, and it is almost always the smallest player.
He measures by the yardstick of lifetime. Every repeated form, every statement requested again, is time that does not come back. For Bairo, a system that remembers what it already knows gives that time back to those who work.
Where this meets the ecosystem
CEASA Bank, an agribusiness financial platform founded by Bairo that operates on the infrastructure of an authorized institution, was designed to turn every sale at the wholesale supply centers into history, so that growers can, with their authorization, show what they have already done. Accounts, payments and credit go through an authorized institution, and part of the design is being implemented.
The BTZ Chain is the ecosystem's public record network, which anyone can check in the explorer, proposed to prove that a fact happened without exposing anyone's personal data. BICOIN, this network's governance coin, follows the yardstick "1 BTZ = 1 minute of human life", which measures purpose and is neither a price nor an invitation to buy.
