RESBit: Brazil's Plan to Integrate Bitcoin into Its Strategic Reserves

Brazil is considering an unprecedented measure in Latin America: the creation of RESBit, a sovereign and strategic reserve dedicated to Bitcoin. The country is currently debating Bill 01/2025 in the Chamber of Deputies, aiming to allocate up to 5% of its foreign reserves—approximately $17 billion—in cryptocurrencies, pending congressional approval. This initiative reflects Brazil’s effort to position itself as a pioneer in government adoption of digital assets.

The Legislative Proposal: Details of RESBit

The bill states that RESBit would operate as a separate sovereign fund from traditional foreign reserves, overseen by the National Treasury. According to lawmakers, this initiative would fund the Bitcoin reserve using assets seized by Brazilian authorities, thus avoiding direct budget expenditures.

RESBit’s structure envisions an allocation of up to 5% of national reserves, around $17 billion. While this amount is significant, it also shows policymakers’ cautious approach, favoring a gradual and controlled adoption of Bitcoin.

Government and Oversight: Control Mechanisms in RESBit

The proposal establishes a governance framework focused on transparency and security. A technical committee composed of representatives from the Central Bank of Brazil and the Ministry of Finance would oversee cold storage and conduct semiannual audits to ensure the integrity of the funds.

This structure aims to mitigate risks associated with digital asset custody. Policymakers believe that a transparent approach, with clear reporting lines and periodic supervision, can make government-held Bitcoin feasible. After a public hearing held in August 2025 before the Economic Development Committee, the bill must undergo further review in the Science and Innovation, Finance and Taxation, and Constitution and Justice committees.

Political Support: The Reasons Behind RESBit

Proponents argue that Brazil risks falling behind in strategic Bitcoin adoption. Data cited indicates that over 25 million Brazilians already invest in digital assets, demonstrating the segment’s penetration into society.

Diego Kolling, representative of Méliuz, compared Bitcoin’s strategic role to an innovation adopted out of necessity. His argument is that delays in state accumulation increase future entry costs, especially considering Bitcoin’s maximum supply of 21 million units. Advocates warn that international governments and sovereign funds could accumulate Bitcoin more quickly, leaving Brazil in a position to buy later at higher prices.

Regulatory Concerns: Risks of RESBit

However, authorities have expressed caution regarding this proposal. Daniel Leal, representative of the Ministry of Finance, argued that Bitcoin’s inherent volatility requires a significantly greater fiscal effort than stable assets.

Additionally, voices within the Central Bank have pointed out that the International Monetary Fund classifies Bitcoin as a non-financial asset, a category that does not easily fit within traditional reserve mandates. This classification raises questions about how to integrate Bitcoin into existing regulatory frameworks without compromising macroeconomic stability.

In light of these concerns, several legislators have supported that RESBit adopt a sovereign fund structure, outside the formal reserve system. This setup would contain risks while testing Bitcoin’s use cases in government contexts.

Future Outlook: The Path Toward RESBit Approval

The debate around RESBit has shifted from ideological considerations to concrete operational issues: how much to buy, how to securely hold the funds, and when to rebalance positions.

The key question remains whether Brazil should treat Bitcoin as a strategic holding comparable to a traditional commodity reserve. If the proposal reaches the plenary and is approved in both chambers, its implementation will depend on factors such as the readiness of custody infrastructure, the establishment of audit procedures, and market liquidity conditions at the time of purchase.

RESBit represents a turning point in how Latin American governments view digital assets, transforming Bitcoin from a speculative phenomenon into a potential component of sovereign financial strategy.
