Brazil's Strategic Bitcoin Reserve (RESBit) Returns: 1M BTC Purchase Plan Sparks Sovereign Adoption Wave
A $68 Billion Bitcoin Gambit Returns to Brazil's Congress
On February 13, 2026, Brazilian lawmakers reintroduced Bill No. 4,501/2024 into the Chamber of Deputies, proposing the creation of a Sovereign Strategic Bitcoin Reserve (RESBit) and authorizing the gradual acquisition of up to one million BTC over five years. If enacted, the roughly $68 billion plan would vault Brazil past the United States — currently the world's largest sovereign holder at approximately 325,000–328,000 BTC — to become the single biggest state-level Bitcoin accumulator on the planet. On the day of reintroduction, Bitcoin rallied 5% in 24 hours, trading near $69,000, according to Bitcoinist.
From Biondini to Gastão: How the Bill Evolved
The original legislation was first introduced in November 2024 by Congressman Eros Biondini. The February 2026 revision, championed by Federal Deputy Luiz Gastão (PSD/CE), represents a substantially expanded version. At its core, the bill establishes SIREBit — the Integrated System for Bitcoin Sovereign Reserves — a governance framework authorizing Brazil's National Treasury to purchase and hold Bitcoin under legislatively defined rules.
The revised bill adds several provisions absent from the earlier draft. Bitcoin would serve as collateral for Drex, Brazil's central bank digital currency, creating a tangible bridge between sovereign crypto holdings and the broader monetary system. Taxes, fees, and fines could be paid in Bitcoin at the prevailing market price. Legal guarantees for self-custody rights would prevent restrictions on transfers to user-controlled wallets. Seized Bitcoin from judicial proceedings would be prohibited from sale and instead redirected into the reserve. Storage must use internationally recognized security protocols including cold wallets and multisignature systems. Semi-annual reports to Congress on custody practices, transactions, and performance would be mandatory.
The acquisition target of one million BTC — approximately 4.8% of Bitcoin's hard-capped 21 million supply — would be spread across five years at roughly 200,000 BTC annually. The bill caps Bitcoin allocation at 5% of Brazil's $344 billion in international reserves and requires compliance with Brazil's Fiscal Responsibility Law.
The Legislative Gauntlet Ahead
According to the Chamber's tracking system, the bill is listed as ready for the agenda in the Economic Development Commission. From there, it must clear the Science and Technology Committee, the Finance and Taxation Committee, and the Constitution and Justice Committee before reaching a full floor vote. No specific timeline has been set.
The most formidable obstacle remains the Central Bank of Brazil (BCB), which maintains that Bitcoin is not recognized as a reserve asset under existing financial rules. This position is particularly significant given that the BCB simultaneously launched a comprehensive regulatory framework for Virtual Asset Service Providers (VASPs) in February 2026, requiring capital reserves between R$10.8 million and R$37.2 million depending on activity type, banning algorithmic stablecoins, and mandating customer asset segregation. Elevating Bitcoin to national reserve status would mark a philosophical U-turn for the institution.
Bill supporters counter by emphasizing gradual acquisition, fiscal responsibility compliance, and the establishment of a specialized advisory committee of digital economy, blockchain, and cybersecurity experts. The legislation also proposes support programs for domestic crypto startups and workforce training initiatives, framing RESBit as an economic modernization vehicle rather than mere speculation.
The Sovereign Bitcoin Arms Race
Brazil's proposal arrives in a rapidly shifting geopolitical landscape. Since the United States established its own Strategic Bitcoin Reserve by executive order in March 2025, sovereign Bitcoin exposure has accelerated dramatically. A 2026 analysis cited by BlockEden reports that 27 countries now have direct or indirect Bitcoin exposure, with 13 more pursuing active legislative measures.
The current sovereign holdings landscape shows considerable concentration. The United States leads with approximately 325,000–328,000 BTC, largely from law enforcement seizures. China holds an estimated 190,000 BTC through similar enforcement channels. El Salvador — the pioneer of deliberate sovereign accumulation — holds roughly 7,500 BTC from direct government purchases. Bhutan controls approximately 6,000 BTC generated via state-linked hydropower mining operations. The United Kingdom holds around 61,000 BTC from enforcement, though without formal reserve designation.
Recent entrants signal broadening momentum. The Czech National Bank purchased $1 million in Bitcoin as an experimental portfolio initiative. Pakistan announced plans for a Bitcoin reserve in 2026. According to CoinShares research, Germany, France, and the Philippines are evaluating similar strategies. Coinbase's John D'Agostino has indicated that additional European nations are assessing sovereign-level Bitcoin exposure.
As CoinShares' analysis emphasizes, sovereign adoption is replacing retail speculation as the marginal buyer — a structural transformation with profound implications for long-term supply dynamics.
Supply Shock Mechanics and Market Impact
The potential market impact of Brazil's proposal is substantial when placed against Bitcoin's supply constraints. Daily mining output currently stands at approximately 450 BTC. Brazil's target of 200,000 BTC annually translates to roughly 548 BTC per day — exceeding total new supply from mining. Combined with existing institutional demand from ETFs, corporate treasuries, and other sovereign buyers already absorbing more Bitcoin than miners produce, Brazilian government purchasing would intensify an emerging structural supply deficit.
As of mid-February 2026, Bitcoin trades in a $65,000–$73,000 range following a roughly 30% decline over the preceding month. Options market data shows open interest climbing to 452,000 contracts, approaching late-2025 highs. Implied volatility has risen approximately 10 points across one-month and three-month maturities. Notably, put-call skew surged from 6% to 18%, indicating strong demand for downside protection — a sign that while the market recognizes upside catalysts, near-term caution prevails, as reported by CoinPaper.
Strategy CEO Phone Le offered a bullish counterpoint in an interview with ETF Trends: "If I look at 2026, I'm pretty excited. I think we're going to see more risk-on buying." Le identified three key drivers: enhanced risk-on sentiment during the mid-term election period, growing bank adoption, and increased nation-state participation.
Latin America's Crypto Acceleration
Brazil's reserve legislation fits within a broader regional trend. Between July 2022 and June 2025, Latin America recorded approximately $1.5 trillion in cryptocurrency transaction volume, according to Chainalysis. Brazil led with $318.8 billion in value received and a period-over-period growth rate of 109.9% — underscoring its position as the region's most dynamic crypto market. The country ranks fifth globally in cryptocurrency adoption.
Neighboring Argentina has emerged as a parallel force, with $93.9 billion in transaction volume and crypto adoption approaching 20% by early 2026, as reported by Blockmanity. Argentina's central bank is considering lifting restrictions on banks offering cryptocurrency services by April 2026, and the country recently introduced its first public Bitcoin treasury model. A notable data point: approximately 90% of crypto flow in Brazil is linked to stablecoins, highlighting that the country's crypto infrastructure already operates at significant scale.
The convergence of Brazil's reserve proposal, Argentina's institutional opening, and Colombia's Bitcoin Medellín 2026 conference reflects a coordinated — if unplanned — regional shift toward digital asset integration at the policy level.
Scenarios and Outlook
Three scenarios merit consideration. In the bull case, the bill clears committee hurdles, perhaps in modified form with reduced targets, and Brazil begins accumulating. This would trigger a domino effect among emerging market nations, compressing available float and adding sustained buy-side pressure. In the base case, the bill advances slowly through committees, establishes a legal framework, but actual purchasing is deferred pending budget appropriations and central bank concurrence. Even this outcome would expand the Overton window for sovereign Bitcoin reserves globally. In the bear case, the central bank's opposition proves decisive, and the bill stalls in committee — though the legislative precedent would remain available for future revival.
The $68 billion price tag — roughly 20% of Brazil's international reserves — represents a genuinely ambitious allocation. Fiscal responsibility constraints, market impact management, and central bank buy-in all present serious practical hurdles. Yet the bill's existence reflects a tectonic shift: Bitcoin is no longer merely discussed as a speculative asset in sovereign policy circles but as a potential instrument of national financial strategy.
Key Takeaways for Investors
Brazil's RESBit legislation signals that sovereign Bitcoin accumulation is transitioning from isolated experimentation (El Salvador) to a competitive, multi-country dynamic. With 27 nations already exposed and 13 more pursuing legislation, the structural demand thesis continues to strengthen. Investors should monitor the bill's committee progress, the BCB's evolving posture, and — critically — whether secondary adoption announcements from European or Asian nations accelerate the timeline. The traditional four-year Bitcoin halving cycle may be yielding to a new paradigm in which sovereign demand, not retail sentiment, determines the marginal price of the world's hardest monetary asset.
