RESBit in Brazil: the bet on Bitcoin as a strategic reserve instrument

Beyond the ideological debate over cryptocurrencies, Brazil is evaluating a concrete initiative that could transform how governments understand reserve accumulation. The bill PL 01/2025, introduced in 2025, proposes creating a Sovereign and Strategic Bitcoin Reserve (RESBit), a fund designed to allocate up to 5% of the national reserves—approximately $17 billion—in Bitcoin. Since the Economic Development Committee of the Chamber of Deputies held a public hearing last August, the text has moved through various specialized committees, bringing Brazil to a turning point in its monetary policy.

Beyond Orthodoxy: Why RESBit Challenges Traditional Consensus

The core proposal of RESBit is not just to accumulate Bitcoin but to recognize a broader geopolitical reality. According to ETHNews data, over 25 million Brazilians already invest in digital assets, reflecting an adoption that policymakers cannot ignore. Diego Kolling, an analyst at Méliuz, has presented a strategic argument: as other governments and international investors accumulate Bitcoin—limited to a total of 21 million units—the entry cost for new buyers will only increase. Waiting longer could mean paying significantly higher prices in the future.

However, this sense of urgency directly conflicts with traditional concerns of central bankers. The Ministry of Finance, through its representative Daniel Leal, argued that Bitcoin’s volatility creates fiscal pressures much greater than those associated with stable assets Brazil is accustomed to. Additionally, the Central Bank pointed out a technical complication: the IMF classifies Bitcoin as a “non-financial asset,” which places it outside the conventional mandates for reserve holdings. This friction led legislators to propose an alternative structure: a sovereign fund operating independently of formal international reserves, allowing experimentation without directly exposing the country’s monetary architecture.

The RESBit Structure: Governance, Custody, and Transparency

The fund’s design reflects a careful balance between ambition and prudence. According to the legislative proposal, RESBit would be managed by the National Treasury under the direct supervision of a technical committee composed of representatives from the Central Bank and the Ministry of Finance. The physical management of Bitcoin would be carried out via cold wallets—offline wallets that minimize cybersecurity risks—an approach demonstrated by other digital asset managers as robust.

Another distinctive element is the funding mechanism: instead of allocating government budget funds, RESBit would be partially capitalized with Bitcoin seized during law enforcement operations. This avoids immediate fiscal spending debates, although full funding would still require Congressional approval. Auditors would conduct semiannual reviews to ensure deposit integrity, and information would be published according to transparency protocols. This control system directly addresses risk concerns, transforming what began as an ideological debate into a discussion about mechanics: what to acquire, how to custody, when to rebalance.

The Legislative Path: From Conceptual Debate to Implementation

Since the August 2025 hearing, RESBit has advanced through committees on Science and Innovation, Finance and Taxes, and Constitution and Justice. The proposal did not face outright rejection, nor immediate adoption, suggesting that the Brazilian Congress sees value in cautious exploration. Support comes from parliamentarians who view RESBit as a mechanism to position Brazil at the forefront of financial innovation, while the technical concerns raised by the central bank are not vetoes but requests for clarification on fiscal risks.

If the project proceeds to votes in both chambers and is approved, its implementation will face immediate practical challenges: establishing secure custody protocols, defining purchase schedules to minimize price volatility impacts, and coordinating with the IMF on how to classify these assets in international reserve statistics. The fundamental question remains: should Brazil treat Bitcoin as a commodity reserve—similar to gold or lithium—or as a monetary policy experiment? For now, RESBit remains a proposal, but its very existence indicates that Latin American governments are seriously considering rewriting what “strategic reserve” means in the digital age.
