Brazil's lower house took a decisive step toward a tougher digital-fraud regime in mid-June 2026. On June 13, the Chamber of Deputies' Finance and Taxation Committee (CFT) approved Bill PL 5819/2025, authored by Rep. Coronel Chrisóstomo (PL-RO) with a favorable opinion from rapporteur Kim Kataguiri. The bill raises prison terms for digital estelionato (swindling) from four-to-eight years to six-to-ten, and — its headline feature — explicitly empowers judges to freeze cryptocurrency balances held on exchanges and platforms while a cyber-fraud investigation is underway. It now heads to the Constitution and Justice Committee (CCJ).
The case for the bill is strong
It would be dishonest to treat this as overreach by reflex. Brazil is in the middle of a genuine digital-fraud emergency. According to figures Febraban submitted to the Chamber and reproduced in Kataguiri's report, scam losses jumped from R$8.6 billion in 2023 to R$10.1 billion in 2024 — a 17% rise in a single year — with Pix-based fraud climbing 43%. The Fórum Brasileiro de Segurança Pública estimates that between July 2024 and June 2025, 24 million Brazilians fell victim to Pix or boleto scams, with losses near R$29 billion. Organized fraud rings increasingly route stolen funds straight into crypto, where prosecutors have lacked a clear legal instrument to freeze assets before they vanish across borders or through mixers. The report frames the crypto-freeze power precisely as filling that 'regulatory gap.' A precautionary freeze that interrupts a laundering chain mid-flight is, in principle, exactly the kind of targeted, proportionate tool a serious anti-fraud regime should have.
Stiffer sentences for professionalized, organized fraud — the bill adds a one-third penalty increase where a criminal organization or industrialized scam structure is involved — also track the reality that this is no longer petty crime. These are factory-scale operations.
Where proportionality breaks down
The problem is not the goal; it is the bill's reach relative to its safeguards. Three features should give a CCJ reviewer pause.
First, asset freezes bite before conviction. The crypto and bank-account freezes are precautionary measures imposed during investigation, on a suspect who is still presumed innocent. Freezing exchange balances can be appropriate, but only with narrow standards: a judicial finding of specific, traceable proceeds, defined time limits, and a fast adversarial route to contest the order. As drafted and described, the freeze power is broad and the procedural guardrails thin. A freeze that lingers for months on contested or commingled funds is not a scalpel — it is a sanction imposed without trial.
Second, the bill reaches well past money. The same precautionary toolkit lets a judge order 'restriction of access to social networks and digital payment systems.' Cutting a defendant off from the messaging or payment rails used to commit fraud sounds surgical, but a court-ordered ban on social-media access pre-trial is a speech restriction, and Brazil already has a fraught record here — recall the nationwide platform blocks debated since the 2024 X/Twitter standoff. A precautionary measure that silences an unconvicted person online is constitutionally heavier than the bill's framing admits, and it belongs nowhere near the routine fraud docket without explicit necessity and proportionality tests.
Third, preventive detention thresholds are blunt. The bill amends Article 313 of the Code of Criminal Procedure to authorize preventive detention where the loss exceeds 100 minimum wages or there is concrete flight risk. A monetary trigger is administratively tidy but a poor proxy for dangerousness; tying pre-trial jail to a damages number invites detention by spreadsheet.
Why the design matters for Brazil's tech economy
None of this is an argument for inaction — it is an argument for precision. Brazil is one of the world's largest crypto-adoption markets and a regional fintech leader; Pix itself is a globally admired public-payments success. A freeze regime that custodial exchanges cannot predict, and that sweeps in self-custodied or merely adjacent wallets, raises compliance cost and legal risk for exactly the regulated, KYC-compliant intermediaries that already cooperate with law enforcement. The likely effect at the margin is to push activity toward non-custodial and offshore venues that ignore Brazilian court orders — the opposite of what prosecutors want.
Better regulation here is not weaker regulation. It is a freeze power confined to identifiable proceeds on custodial platforms, with statutory time caps, mandatory periodic judicial review, and a clear carve-out distinguishing a suspect's traceable fraud gains from their general assets. The speech-restriction provision should be severed or, at minimum, subjected to a strict-necessity standard. And detention should turn on conduct and flight risk, not a loss threshold alone.
The road ahead
The CCJ exists precisely to test constitutionality and drafting quality, and this bill needs that scrutiny. The fraud numbers are real and the public demand for action is legitimate; a publication that backs the open internet and a thriving tech sector should say so plainly. But the strongest anti-fraud laws are the ones courts can apply consistently and intermediaries can comply with predictably. PL 5819/2025 has the right target. It still needs the discipline to hit only that target — and not the due-process and free-expression guarantees standing next to it.
