BNP Paribas and JPMorgan Shift to Public Ethereum: The Institutional Migration from Private DLT

• BNP Paribas Asset Management officially transitioned its tokenization infrastructure from private blockchain pilots to the public Ethereum network in February 2026, targeting wholesale liquid assets.
• JPMorgan has expanded its USD deposit token deployment on an Ethereum Layer-2 network, commanding an estimated 40% of the current institutional tokenized deposit market volume as of mid-2026.
• The OCC's implementation of the GENIUS Act custody rules is forcing corporate treasuries to integrate with regulated stablecoin layers, while EU MiCA enforcement post-July 1, 2026, demands robust public chain solutions for compliance.
• Broadridge and other data providers are introducing integrated infrastructure to solve the "oracle problem," ensuring off-chain legal events reflect instantly on-chain for institutional investors.
• This convergence marks a validation of public Ethereum as the primary settlement layer for European and US banks, driven by the need for collateral efficiency and regulatory clarity.

Why are major banks moving from private blockchains to public Ethereum?

Major financial institutions are shifting from private Distributed Ledger Technology (DLT) pilots to public Ethereum infrastructure to leverage finality, liquidity, and cost efficiencies that private networks cannot match. This migration is no longer experimental; it is becoming the standard for large-scale corporate treasury and settlement operations.

In February 2026, BNP Paribas Asset Management became the first high-profile European bank to officially transition its tokenization infrastructure from a private blockchain pilot to the public Ethereum network [URL 81]. Unlike standard retail tokenization, this move targets tokenized money market fund shares and wholesale liquid assets. The bank utilized permissioned tokens on Ethereum to restrict access to eligible participants while leveraging the public ledger's finality [URL 82]. This decision marks a significant validation of public Ethereum as the settlement layer for large European banks seeking to improve collateral efficiency without leaving the public ecosystem.

How is JPMorgan’s deployment impacting the institutional market?

JPMorgan is driving parallel adoption in the US market through its expansion of USD deposit tokens on an Ethereum Layer-2 network. As of mid-2026, this initiative represents one of the largest institutional efforts to utilize public Ethereum L2s for "on-chain cash" management, aiming to reduce T+2 settlement friction for corporate clients [URL 139].

JPMorgan's strategy is distinct in its scale. According to estimates, JPMorgan now commands roughly 40% of the current institutional tokenized deposit market volume [URL 137]. By leveraging Layer-2 solutions, the bank addresses scalability and cost concerns inherent to the base layer, while maintaining the security guarantees of Ethereum. This approach reduces settlement friction for corporate clients, making same-day settlement feasible for large-volume transactions.

What role do GENIUS Act and MiCA regulations play in this shift?

Regulatory frameworks are not hindering Ethereum adoption; they are actively pushing institutions toward compliant public chains. The Office of the Comptroller of the Currency (OCC) issued proposed rules in February/March 2026 to implement the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act [URL 101]. These rules impose strict requirements on OCC-regulated institutions acting as custodians for Permitted Payment Stablecoin Issuers (PPSIs). It mandates where and how reserve assets must be held, effectively forcing corporate treasuries to integrate with regulated, compliant stablecoin layers on Ethereum [URL 102]. Comments on these rules closed in May 2026, with final rulemaking expected in Q3 2026 [URL 103].

In the EU, the landscape is equally decisive. The MiCA transitional period ended on July 1, 2026. As of August/September 2026, national competent authorities are actively enforcing authorization requirements [URL 92]. Crypto-Asset Service Providers (CASPs) and issuers facilitating tokenization projects must now hold full MiCA licenses. Non-compliant entities face expulsion from the EU market [URL 146]. This enforcement wave validates the "Public Ethereum" strategy: if banks cannot rely on grandfathering, they must build robust, auditable public chain solutions that meet MiCA's strict reserve and consumer protection standards [URL 149].

How is infrastructure evolving to support institutional needs?

The migration to public Ethereum requires solving the "oracle problem"—ensuring that off-chain legal events, such as dividend payments or KYC status updates, are instantly reflected on-chain. Major financial data providers like Broadridge are addressing this by introducing integrated infrastructure to manage both tokenized securities and traditional assets on a single platform [URL 156]. This convergence allows institutions to maintain their legacy systems while settling on Ethereum, reducing operational friction.

Adoption is also driven by investor demand for security. According to Yole/Deloitte Insights, over 80% of institutional investors surveyed cite "custody security and regulatory compliance" as top gating factors for Ethereum integration in 2026 [URL 127]. This statistic underscores that technical features are secondary to legal and security assurances. Institutions are not just adopting Ethereum for its technology, but for its ability to provide a compliant, auditable, and secure environment for high-value transactions.

What does this mean for future enterprise blockchain roadmaps?

The convergence of BNP Paribas and JPMorgan's strategies signals a clear industry trend: Ethereum is becoming the default settlement layer for tokenized assets. Enterprises can no longer treat private DLT as a viable long-term alternative for high-volume, cross-border settlements due to liquidity fragmentation and regulatory complexity. The combination of US GENIUS Act custody rules and EU MiCA enforcement creates a unified global pressure toward compliant public infrastructure.

For corporate treasuries, the implication is immediate: readiness for public chain integration is no longer optional. With broad data provider support and established custody frameworks, the path to tokenizing wholesale assets is now technically and legally mature. Institutions that delay this integration risk falling behind in collateral efficiency and settlement speed.
