On 22 June 2026 the Federal Public Ministry (MPF) issued a public notice that sent a clear signal to every political party and campaign: cryptocurrency donations are still prohibited.

The warning, part of the MPF’s “Me explica, MPF!” series, simply echoes a rule that has been in force since 2019. The Superior Electoral Court (TSE) issued Resolution 23.607/2019 on 17 December 2019, declaring that any campaign contribution must be traceable so that election authorities can verify the donor’s identity. Because most virtual‑currency transactions are pseudonymous, they do not satisfy the transparency requirement.

Under the current framework, campaign funds must flow through channels that identify both the donor and the recipient. The MPF noted that the Pix payment system, operated by the Central Bank, and traditional bank transfers are acceptable because they provide the necessary identification. Crowdfunding is also allowed, but only through platforms that are registered and authorized by the TSE.

Violations of the ban can trigger several penalties. Parties and candidates may face fines, be required to return the money to the National Treasury, or be subject to proceedings alleging abuse of economic power. The notice arrives at a critical time, as Brazil’s general election is scheduled for 4 October 2026, with a possible runoff on 25 October.

The crypto donation ban is separate from recent restrictions on prediction markets. In April 2026, Brazilian authorities limited platforms that offered contracts tied to political, electoral, social, cultural, and sports events. The measure affected platforms such as Polymarket and Kalshi and was reported by Reuters to have blocked 27 prediction‑market sites, restricting event contracts to areas such as economic indicators.

Brazil’s regulatory approach to digital assets has been consistently tightening. In May 2026 the country blocked the use of crypto within regulated cross‑border payment rails, keeping virtual assets out of supervised eFX settlement. Earlier this year, the government announced a new audit mandate for crypto exchanges seeking authorization. Lawmakers also advanced a bill to ban algorithmic stablecoins and require domestic issuers to fully back their tokens.

Despite these restrictions, Brazil remains one of Latin America’s largest crypto markets. The country’s regulatory environment continues to define where crypto can operate, balancing the need for transparency in public finance with the broader adoption of blockchain technology.

The MPF’s reminder does not introduce new legislation; it restates the 2019 rule. For parties and candidates, the message is clear: campaign money must be identifiable, and crypto donations do not satisfy that standard under current election rules.

The upcoming election cycle will test the enforcement of these regulations. Political actors will need to ensure all contributions are routed through approved channels, and regulatory bodies will likely monitor compliance closely. Any deviation could result in the penalties outlined by the MPF.

In summary, Brazil’s election finance law maintains a strict prohibition on cryptocurrency donations, citing the need for donor traceability and transparency. The rule, reinforced by the MPF’s recent notice, remains in effect as the country prepares for the 2026 general election.
