SEC Commissioner Hester Peirce has put forward a proposal suggesting a collaborative digital securities sandbox between the United States and the United Kingdom. This initiative, introduced on May 29, aims to integrate U.S. firms into the Bank of England and Financial Conduct Authority's (FCA) upcoming digital securities sandbox (DSS), scheduled to begin accepting UK applications later this summer.

The proposed sandbox would enable participating firms to operate under harmonized regulatory conditions spanning both countries. This alignment would facilitate the sharing of regulatory information between the U.S. and UK, streamlining compliance efforts for firms involved.

Participants in the sandbox would have the flexibility to define their regulatory parameters and utilize the environment to validate their products in the market, identify operational challenges, and serve actual customers. The primary objective is to assess whether distributed ledger technology (DLT) can support securities issuance, trading, and settlement efficiently and securely.

Key aspects of Peirce's proposal include broad eligibility criteria for firms not categorized as bad actors, allowing them to engage in various activities within the sandbox. Participation would typically span two years, during which firms would be required to publicly disclose their involvement. The SEC's Strategic Hub for Innovation and Financial Technology (FinHub) would play a supportive role, assisting firms with participation notices and providing guidance on no-action letters and exemption orders.

To maintain integrity, the SEC would enforce anti-fraud measures and monitor compliance with the self-selected regulatory conditions set by sandbox participants. Peirce addressed concerns surrounding firms choosing their regulatory framework, emphasizing the necessity for these conditions to be reasonable and conducive to investor protection.

Highlighting potential benefits, Peirce underscored that previous UK FCA sandbox participants from 2016 to 2019 had notably raised more capital and sustained longer durations compared to non-participating firms. She pointed to a 2019 survey indicating support for this regulatory approach among regulators.

The proposal emerges amidst scrutiny of the SEC's recent actions under Chair Gary Gensler, particularly concerning enforcement actions against crypto firms and the approval process for spot ETH ETFs, which have faced allegations of political influence.

Peirce clarified that her proposal is still in development and not yet an official SEC initiative. While her earlier Safe Harbor Proposal, aimed at providing temporary regulatory exemptions for token issuers, has seen limited progress since 2021, Peirce remains committed to fostering regulatory innovation and enhancing market access for new financial products.

As discussions progress, stakeholders will monitor developments closely to assess the potential impact of this cross-border regulatory collaboration on the evolving landscape of digital securities and blockchain technology.
