Brazil’s central bank (BCB) is preparing a dedicated regulatory regime for B2B virtual asset service providers (PSAVs), a segment including Fireblocks, BitGo, Paxos, Ripple and other institutional infrastructure operators. This marks a transition from consumer‑facing oversight to supervision of wholesale digital‑asset infrastructure. The initiative occurs alongside a deepening review of foreign‑currency‑referenced stablecoins, which the BCB increasingly associates with cross‑border financial flows. Together, these measures signal a structural shift that is likely to reshape market access, standards of governance and the operational perimeter for DeFi‑linked institutional services in Brazil between 2026 and 2027.

Context and Regulatory Drivers

The BCB has already implemented Resolutions 519, 520, and 521, issued Normative Instructions 693, 701, and 704, and, in November 2025, published its first comprehensive cryptoasset framework, which classified certain crypto transactions as foreign‑exchange operations. The forthcoming phase targets PSAVs operating exclusively in B2B capacities—liquidity providers, custodians, embedded‑wallet infrastructure operators and crypto‑as‑a‑service platforms.

These entities facilitate multi‑institutional settlement flows and support high‑volume stablecoin operations. Infrastructure providers such as Fireblocks process more than $200 billion in monthly stablecoin activity (2025) and secure over $10 trillion in transactions across 120–150 blockchains. Their role as wholesale liquidity, custody and orchestration layers introduces supervisory concerns typically absent from retail‑centric crypto regulation.

The BCB's central challenge is that PSAVs operate without a central counterparty or organized exchange infrastructure. Bilateral liquidity networks, shared technology stacks and cross‑jurisdictional settlement raise questions about risk propagation and the adequacy of existing prudential controls.

Market Impact and Structural Consequences

The planned regime will likely recalibrate competitive dynamics in Brazil’s digital‑asset sector:

  • Higher operational thresholds. Compliance expectations surrounding governance, documentation of foreign‑linked flows and AML/transaction‑monitoring frameworks will pressure smaller entities. The professionalization effect noted by domestic legal analyses aligns with global trends, where technical sophistication and audited controls increasingly determine market viability.
  • Liquidity network consolidation. Institutions offering multi‑node, high‑throughput infrastructure—such as architectures operating across multiple blockchain nodes with automated fallbacks—are structurally advantaged. These capabilities support the BCB’s expectations for reliability in wholesale environments.
  • Stablecoin market realignment. With stablecoins treated as operations with potential FX impact, distribution models are likely to shift toward supervised intermediaries capable of full reporting, flow mapping and reconciliation.

The transition period (extending to October 2026 for entities already operating) maintains operational continuity but restricts expansion, preventing unassessed business lines from scaling ahead of regulatory clarity.

Regulatory and Supervisory Considerations

The BCB’s upcoming rules are expected to emphasize four pillars: authorization, governance, transaction transparency and stablecoin reserve oversight.

Authorization Criteria

Entities must demonstrate pre-existing activities, provide complete operational documentation and undergo continuous assessment. Permission to continue operations is temporary until full authorization is granted.

Governance and Controls

Given rising global security incidents—over $3.4 billion in crypto stolen in 2025 and more than $17 billion since 2020—regulators are increasingly attentive to operational resilience. Providers must demonstrate mature governance, evidence of segregation of duties, embedded cybersecurity processes and audited key‑management frameworks.

Transaction Reporting and Surveillance

Classifying stablecoin transactions as FX‑linked triggers new reporting duties. Institutions must:

  • map all flows, including interactions with foreign counterparties
  • document internal wallet movements treated as cross‑border exposures when involving foreign‑linked assets
  • provide structured data in formats the BCB can integrate into systemic risk monitoring

The absence of a central counterparty elevates the importance of robust surveillance tools. The BCB will likely push for real‑time or near‑real‑time visibility into settlement life cycles.

Stablecoin Reserve Requirements

The BCB is assessing reserve quality criteria for foreign‑currency stablecoins. This includes permissible collateral, liquidity thresholds and transparency standards. These measures align with ongoing global debates on stablecoin reserve composition.

Product and Structuring Implications

Institutional product design will need to adapt across custody, settlement and liquidity provision.

  • Custodial segmentation. Clear differentiation between client assets, omnibus flows and operational wallets becomes central. Multi‑node and fallback architectures will support the resilience standards anticipated by regulators.
  • Stablecoin distribution. Providers distributing or integrating foreign‑currency stablecoins must treat issuance, redemption and onchain transfers as potentially FX‑relevant. Policies must address reserve disclosures, flow monitoring, and user suitability.
  • B2B liquidity services. In the absence of a central counterparty, liquidity providers may need standardized agreements, margining frameworks or bilateral exposure management protocols to satisfy supervisory expectations.
  • Embedded wallet solutions. As companies can deploy thousands of wallets within seconds, functional segmentation and access control must be explicitly designed to satisfy regulatory expectations around client identification and operational traceability.

Risk Assessment and Sectoral Exposures

The emerging framework will influence multiple categories of risk.

Market and Liquidity Risk

Stablecoins’ increasing association with FX markets means liquidity mismatches or redemption disruptions may propagate into domestic payment flows. PSAVs handling large volumes—more than 300% year‑on‑year growth in stablecoin transfers for some platforms—may face new liquidity buffers or reporting rules.

Counterparty and Credit Risk

Bilateral settlement networks require institutions to assess the creditworthiness of counterparties without relying on a central clearing entity. Regulators may demand formalized risk‑scoring and monitoring systems.

Operational and Cybersecurity Risk

High‑volume operators must mitigate elevated threat levels, including groups responsible for a substantial share of industry attacks. Failure to demonstrate hardened operational controls could affect authorization outcomes.

Improper structuring of stablecoin flows risks classification as unauthorized FX intermediation. Entities reliant on foreign settlement rails must document how operational arrangements fit within domestic constraints.

Operational Implementation Considerations

Market participants face near‑term implementation challenges:

  • comprehensive mapping of all stablecoin flows, including back‑office movements
  • revision of internal policies to incorporate FX‑linked classifications
  • deployment of reconciliation systems capable of producing structured reporting
  • evaluation of outsourcing chains, especially where foreign providers manage key custody elements
  • preparation for authorization filings within the 270‑day window

Providers already using multi‑node blockchain architectures or automated fallback mechanisms may find compliance alignment less burdensome, given the emphasis on resilience.

Forward Outlook

The BCB’s two‑stage regulatory expansion aims to integrate PSAVs into a supervised institutional perimeter while addressing the systemic relevance of stablecoins. The outcome is likely to be a smaller number of larger, better‑capitalized and more controlled infrastructure providers. For DeFi‑linked institutional services, the most immediate effect will be a tightening of operational and reporting standards rather than outright prohibition. Over 2026–2027, the framework is expected to converge Brazil’s digital‑asset market with broader financial‑sector norms, enabling incremental integration of onchain infrastructure into domestic capital‑market and payments operations.
