(Im)positive Register: Brazil's Central Bank will share your data with credit reporting agencies

Brazil’s Central Bank (BCB) has published this Monday in the Official Gazette extracts from agreements with five major consumer credit reporting agencies in Brazil to share data about Brazilian bank clients:

The terms of the agreements state that they are to come into effect immediately after this publication (which is September 4th, 2023), and also state that they are to remain in effect indefinitely.

The agreements had been announced in March by the BCB in a note on its website, without much fanfare, and to no effective repercussion at all, considering that I couldn’t find a single news article that mentioned them.

The existence of such agreements for sharing data with credit reporting agencies had been provided in a bylaw from 2022, Resolução CMN no. 5,037:

Article 10. The Central Bank of Brazil may make available to managers of databases registered under the terms of article 12 of Law No. 12,414, of June 9, 2011, the information of the SCR on credit operations in compliance or in progress of those registered in those databases, respecting the rules established in this Resolution and in complementary regulations issued by the Central Bank of Brazil.


§ 3rd. The availability of the information referred to in the caput is conditional on the establishment of an agreement between the database manager and the Central Bank of Brazil.

§ 4th. The agreement referred to in the 3rd. paragraph of this article shall establish the manner in which the exchange of information between the parties shall take place.

However, only someone who had been following very closely the Central Bank’s regulations on this sector is likely to have seen it coming. When compared to the widespread, dragnet surveillance effect that these data sharing agreements entail, which is bound affect most Brazilians, one could very easily argue that the agreements will take many people by surprise.

What data will be shared?

The BCB will share with credit reporting agencies data contained in the Credits Information System (SCR). The bylaw that regulates the system, Resolução CMN no. 5,037, contains a non-exhaustive list of what it considers to be credit operations, which are to be included in the system. The list is long and hard to understand, let alone translate to English, to anyone who isn’t savvy in the financial sector jargon. But it seems to include but not be limited to loans, mortgages, pawn and other modes of financing.

According to BCB’s description of the system, they receive this data monthly from financial institutions (public and private banks) in order to monitor financial operations and prevent crises. They also assert that it does not violate bank’s secrecy and that the client’s privacy is preserved,

as it requires that the financial institution obtains express authorization from the client in order to access information about him or her.

That may well apply to the case where someone is applying for a loan and the bank offers to access SCR in order to ascertain risk, and for that it obtains an express authorization directly from the client. However, that does not seem to be the case with the data sharing with credit reporting agencies enabled by those new agreements, as it does not seem plausible that the agency would obtain express authorization from each and every person in the registry before obtaining the data from SCR.

Update: see this later post for more accurate information on what kind of data is being shared.

With whom will the data be shared?

The credit reporting agencies are private data brokers that collect personal and financial data about people and companies, maintaining large databases of their financial information, and calculates credit scores based on that data. They then sell access to credit scores and payment history to third parties interested in that data.

Brazil’s data protection law (LGPD) does not require that credit reporting agencies in Brazil are obtain consent from people in order to use their data (Article 7, X). That alone means that citizens get weaker protection from the use that those data brokers make from personal data, as long as they claim that using the data is required for credit protection.

Furthermore, in 2019 Complementary Law no. 166 provided for automatic inclusion of every Brazilian citizen in the (Im)positive Registry (in Portuguese, Cadastro Positivo), under an opt-out regime. It means that, unless someone explicitly notifies the credit reporting agencies that they want to be excluded from the registry, their data will be included in this private financial dragnet surveillance network. In order to exercise your right to opt-out, however, you often have to provide them with even more personal information, such as the CPF (Brazilian’s unique universal identification number), full name, date of birth, home address, e-mail, phone number, and sometimes even a selfie. At least the law states that once excluded from the registry in any one of the credit reporting agencies, all others are obliged to also follow through with the removal from their own databases.

Information on the (Im)positive Registry includes all sorts of payments and loans. Even public facility operators, such as electricity, water and sanitation and gas companies are obliged to send personal and financial data about their customers to the credit reporting agencies.

The supposed benefits of the (Im)positive Registry

At the time that law was enacted, a few privacy experts and consumer protection activist organizations criticized the mandatory and automatic inclusion. Part of the press also seemed skeptical to the claim that the measure would reduce the cost of credit: just because financial institutions would be able to assess risk more precisely does not automatically mean they would lower interest raters.

On the other hand, another part of the press just repeated the same arguments presented by these companies’ lobbies: that having everyone automatically included in the (Im)positive Registry would improve everyone’s credit score and lower the bank spread, which is the difference between the base interest rates paid in government bonds and the interest rates practiced by banks to their clients.

That argument for the law is based on several wrong assumptions: that everyone is interested in trading off their privacy for credit worthiness, valuing the latter much higher than the former. That everyone is interested in taking credit all the time, rather than at very specific points in their lifetime, such as when purchasing a home. Or even that people nowadays share everything about themselves and their lives on social networks anyway and are not interested in their own privacy.

Even if, for the sake of argument, we take their reasoning at face value, a report issued by BCB itself in 2021 has determined that, as an effect of the automatic inclusion of everyone in the (Im)positive Registry,

about 41% of people have migrated to a lower risk of credit category as a result of inclusion in the (Im)positive Registry, 33% have remained in the same risk category, and 26% have migrated to a greater risk category.

While some people (41%) have had improvements on the credit assessment as a result of using this data, a much higher proportion (59%) have either remained the same or have had their creditworthiness reduced. This does not seem like an advantageous tradeoff for most people, if it means that they have to give up on the privacy of their personal and financial data.

As for the behavior of bank spreads,

it found out that in comparison to the new borrowers who did not have scores based on the Positive Register, those who had them had an average reduction of 10.4% in the spreads of non-payroll personal loan operations. This decrease is equivalent to 31 p.p., when considering the average interest rate of 299% per year observed in this sample of operations.

Banks have been offering loans, according to this empirical study, during that time period, with a “discount” of only 31 percent points out of the exorbitant average interest rate of 299% a year. That seems way too little, especially considering that the period measured had been very atypical when considering interest rates in Brazil. In 2020 and 2021, with a reasoning that they need to stimulate the economy during the pandemic, the Monetary Policy Council had reduced the base interest rate to a historic all-time low of less than 2% per year. This is even lower than the inflation rate measured for the period, counting as an effective negative rate for the first time in decades, if not ever. The report does not even take in consideration that extraordinary fact and presents this meager result as if it was a positive effect of having the mandatory automatic inclusion in the registry.

We can safely affirm that, 4 years after the law, few people have benefited from the automatic inclusion in the registry (the opt-out regime) except the credit report agencies themselves.

Risk of data breaches

One more reason to worry about sharing personal and financial data with credit reporting agencies is the risk that that vast trove of data will leak and end up in the hands of criminals.

This type of data broker has been reported in the news to be the suspected source of a 2021 massive data breach of more than 223 million Brazilians. The data includes name, CPF, date of birth, home address, phone, face photo, educational degree, pension status, tax filings and credit score. The number of people exceeds the total population of Brazil, accounted for as 203 million people in the official 2022 census, because it reportedly also includes personal data on deceased people.

Civil society organizations that advocate for consumer protection, such as IDEC, have raised serious concerns about the (Im)positive Registry and about millions of people having been put in risk of being targeted by criminals as a result of this data breach. The National Data Protection Agency (ANPD) declared, at the time, that they would be investigating the breach. However, more than 2 years later, we have yet to see any consequence come out as a result of that investigation.

The data brokers themselves have denied being the source of the data breach. Some have even taken that opportunity to offer a paid service for people to check with them whether or not their personal data has been found on data breaches on the “dark web”. The move is so ironic that one could easily call them out for making themselves a poster child for the term “privacy washing” – used to indicate when companies try to present themselves to the public as privacy conscious, when in fact they do the opposite in internal practice.

How do I stop my data from being shared?

The only way to prevent your data on the SCR system from being shared with the credit reporting agencies is to manifest your right to opt-out of the (Im)positive Registry. That much is clear from Resolução CMN no. 5,037, Article 10, paragraph 2nd:

It is forbidden to make available the information referred to in the caput about those registered who opt for the cancellation referred to in item I of article 5 of Law No. 12,414, of 2011.

Cancellation can be done at any of the credit reporting agencies by online form, by phone, by mail (letter) or supposedly even in person at some service points, depending on which agency you request. The caveat is that whatever the requesting medium used, they’ll likely try to get as much personal information out of you as they can, with the excuse of “identity verification”, to make sure it is really you requesting exclusion. The challenge lies in figuring out which one of them demands providing fewer data in exchange.
