Financial Market: main news from 24 to 28/08

On Monday (August 24), during FEBRABAN TECH 2026, Caio Moreira Fernandes, head of the Information Technology Department (Deinf) at the Central Bank of Brazil (BCB), stated that the BCB is negotiating partnerships with technology companies and financial institutions to secure early access to artificial intelligence models that are still under development, with a view to identifying risks and preparing the financial system for emerging threats. Key risks include the use of AI to identify vulnerabilities and scale up cyberattacks, as well as the impact of quantum computing on current encryption mechanisms. The initiative draws on international projects that provide early access to AI models, enabling vulnerabilities to be identified before the models are released to the market. During the panel, participants also noted that some institutions still operate fragmented security architectures comprising different systems and tools that do not always integrate. The trend identified is a move towards “context-aware security”, capable of consolidating different alerts and information to identify not only isolated events but also the broader context of potential incidents. For the financial sector, staying ahead of technological advances and integrating security layers are considered essential to strengthening prevention and incident response.

On Monday (August 24), during FEBRABAN TECH 2026, the financial sector’s largest innovation and technology event, Janaína Attie, a consultant at the BCB, stated that the primary challenge for Open Finance in Brazil has shifted to ensuring the quality of data shared among institutions, following the consolidation of the infrastructure and data-sharing journeys. According to Attie, institutions can already communicate with one another, and customer journeys are functioning, but data quality must be improved to increase the value delivered to customers. Open Finance marks six years of regulation this year and has already exceeded 135 million active data-sharing consents. The BCB is also working on initiatives to improve data quality and advance salary and investment portability. In Attie’s view, although Brazil is a global benchmark in this area, there is still room to expand the system’s benefits, particularly in terms of effectiveness, quality and security.

Hypernative announced that the BCB is moving forward with the contracting process following a proof of value demonstrating the feasibility of implementing a continuous monitoring system for virtual-asset fraud. The tool is intended to identify suspicious transactions and patterns in real time, including signals that may precede the transfer of proceeds of fraud into the virtual asset market. According to Regina Pedroso, executive director of the Brazilian Association of Tokenization and Digital Assets (ABToken), the solution has already been tested using Brazilian market data. According to Hypernative’s statement, in one case, the system issued an alert 14 hours before the movement of funds subsequently linked to a confirmed fraud incident. The initiative also provides for alerts to be shared with industry associations, which will then distribute them to their members. According to Pedroso, one of the BCB’s concerns is improving the traceability of funds as they leave the traditional financial system and enter the virtual asset market, including through digital wallets.

On Wednesday (August 26), the BCB announced it had begun providing more timely information on credit transactions conducted within the National Financial System (SFN). Following the issuance of BCB Resolution No. 413/2024, BCB Normative Instruction No. 530/2024 and BCB Resolution No. 516/2025, events such as credit originations, assignments, portability transactions, installment payments and settlements are now recorded daily and reported to the Credit Information System (SCR) within 5 business days. In practice, information that previously took up to 45 days to appear in credit bureau inquiries is now updated within 7 business days, allowing individuals and companies to have their creditworthiness assessed using more recent data. Initially, the faster updates are available only through the credit bureau, while the BCB works to implement the same process in Registrato.

On Thursday (August 27), Anbima, the Brazilian Financial and Capital Markets Association, launched its PDD Methodology Guide (Provision for Doubtful Debts in Securitization Assets), prepared in cooperation with market participants. The document sets out good practices to assist securitization companies in measuring, recognizing and monitoring credit risk, with a focus on improving transparency, comparability and governance in structured transactions. Among its recommendations are the adoption of an expected-loss methodology, the assessment of the recoverability of assets and collateral, the establishment of provisioning triggers and the periodic review of PDD levels. The guide also introduces the so-called “wagon effect”, under which a material deterioration in the credit risk of a particular debtor or economic group may require a review of the provisions applicable to related assets. The document is for guidance purposes only and does not form part of Anbima’s self-regulatory rules.
