Background & Biography
Ribeiro’s parliamentary career began on 1 February 2011, when he took office as a federal deputy for Rio de Janeiro. The Chamber records four consecutive terms, covering 2011–2015, 2015–2019, 2019–2023 and 2023–2027, and lists his professional background as an entrepreneur. Its current record identifies him as an active deputy for the 2023–2027 term and Solidariedade’s Chamber leader since February 2023. These elected and parliamentary posts establish Brazil as his professional jurisdiction for this profile.
His original cryptocurrency proposal was filed on 8 July 2015. Its initial scope joined virtual currencies and airline mileage programmes to the discussion of payment arrangements supervised by the central bank. The docket retains that earlier description alongside the substantially different text that later emerged from the legislative process.
By October 2021, Ribeiro was chairing the Chamber’s Financial Oversight and Control Committee. At a hearing that month, he argued that regulation should provide legal certainty, particularly for small investors, and improve the information available to people using cryptoassets. Agência Câmara reported that he intended to seek urgent consideration of his bill after its approval by a special committee. The intervention connects his legislative initiative to a practical concern: whether consumers could identify and understand the businesses handling their money.
Notable Contributions
The Chamber approved PL 2303/2015 on 8 December 2021. Agência Câmara distinguished Ribeiro, the bill’s author, from Expedito Netto, the rapporteur whose substitute text was adopted. The proposal addressed businesses carrying out exchanges, transfers, custody and related virtual-asset services for customers. It also set out regulatory responsibilities and principles concerning governance, risk management, data protection, consumer protection and financial-crime prevention. This was a legislative milestone in the passage of a framework, with further consideration by the Senate still required at that point.
The process culminated in Law 14.478, sanctioned in December 2022. Agência Senado identified Ribeiro as the originating bill’s author while recording contributions from Senator Soraya Thronicke’s proposal and Senator Irajá’s work as Senate rapporteur. The resulting framework addressed virtual-asset service providers and fraud. Its passage was therefore a collective parliamentary and executive outcome, with Ribeiro’s initiating role clearly identifiable within it.
On 13 June 2023, Ribeiro was elected chair of the parliamentary inquiry commonly known as the CPI das Pirâmides Financeiras. Its opening minutes record fifteen votes for him and two blank votes. The commission’s stated remit concerned suspected fraudulent schemes involving cryptocurrency-related financial services during 2019–2022. Ribeiro explained that investigative work would proceed through requests approved by members and established procedures for hearings and submissions. The minutes demonstrate a formal oversight responsibility; they do not establish the truth of allegations against any particular business or individual.
Ribeiro subsequently acted as rapporteur on PL 4932/2023, a bill originating from that inquiry. On 12 November 2024, the Chamber approved his substitute text, which was read to the plenary by Marcelo Queiroz. Agência Câmara described proposals for customer identification, internal controls, reporting to the financial-intelligence body Coaf and transfers through accounts held in users’ names. The proposal also sought separation of customers’ money and virtual assets from a provider’s own property, including protections if the business entered insolvency. These were features of the Chamber-approved proposal, not a claim that every provision had become law.
A further initiative, PL 4308/2024, was introduced by Ribeiro on 11 November 2024 specifically to address stablecoins. The Chamber docket records approval of a substitute by the Science, Technology and Innovation Committee in December 2025, under rapporteur Lucas Ramos. At the October 2026 research check, the proposal was awaiting a rapporteur’s opinion in the Economic Development Committee; a hearing request had been approved in June 2026. This continuing scrutiny matters when assessing his record: introducing the bill and advancing it through one committee are distinct from securing final enactment.
Why Katharos.ai Follows Aureo Ribeiro
Ribeiro’s own December 2021 plenary intervention helps explain his approach. He described a process of specialist hearings, discussion with public authorities and examination of experiences abroad. He linked a clearer regulatory environment with investment and argued that users needed to know where and with whom they were transacting. That argument makes service-provider accountability central to his policy contribution.
His position also includes criticism of particular regulatory choices. In an exclusive EXAME interview published on 16 June 2025, Ribeiro objected to proposed cryptocurrency tax changes in Provisional Measure 1.303. He argued that removing an exemption affecting smaller transactions would disadvantage people entering the market, while some larger investors would face lower rates. He called for legislative changes and framed participation, innovation and fairness as priorities. These are his attributed arguments about the proposal at that time. The interview is evidence of his stance, rather than an assessment of the tax rules applicable to a reader today.
Areas to Follow
The progress of customer-asset protections remains a specific legislative question. The Senate’s PL 4932/2023 docket, checked in October 2026, still listed the bill as in progress in its Economic Affairs Committee, with Irajá as rapporteur. The recorded action on 7 April 2026 was its removal from that meeting’s agenda, while the matter remained ready for a committee agenda. Subsequent amendments, votes and any final text will determine the outcome of the initiative Ribeiro reported in the Chamber.
Implementation of the broader framework also involves separate regulatory decisions. A February 2026 Banco Central document records the bank’s designation as virtual-asset service regulator in 2023 and the issuance of Resolutions 519, 520 and 521 in November 2025, covering authorisation, service-provider operation and foreign-exchange treatment. Those measures provide context for evaluating later legislative proposals. They are institutional acts of the regulator, and this profile does not attribute their technical drafting or adoption to Ribeiro.
