SEC Proposes Broker Custody for Tokenized Stocks Despite Onchain Trading

The U.S. Securities and Exchange Commission (SEC) has proposed a regulatory framework mandating that broker-dealers maintain custody of tokenized securities, including tokenized stocks, regardless of their onchain trading and settlement. This development raises critical questions about how traditional securities regulations will intersect with blockchain-based financial innovation and what it means for investor autonomy and the future of decentralized finance (DeFi).

What happened

The SEC recently put forward a regulatory proposal requiring broker-dealers to hold custody of tokenized securities, a category that includes tokenized stocks traded on blockchain platforms. This custody requirement applies irrespective of whether the securities exist as conventional paper certificates or as digital tokens on distributed ledgers. The stated purpose of the rule is to align tokenized securities with existing investor protection frameworks that emphasize safeguarding client assets under broker control.

Tokenized stocks are digital representations of traditional equity securities issued and settled on blockchain networks, enabling peer-to-peer trading without intermediaries. Despite this fundamental shift in how ownership and transfer are recorded and executed, the SEC insists that broker custody rules must still apply, bridging digital asset innovation with established securities law.

The agency’s position reflects its broader mandate to regulate securities markets and enforce investor protections, including prevention of fraud and theft. According to SEC statements, requiring brokers to maintain custody ensures accountability and security within tokenized securities markets.

Independent analyses provide further context: a Harvard Law School Forum report highlights that the SEC’s custody requirements may restrict the operational autonomy of DeFi platforms, which typically function without centralized intermediaries. Similarly, a Financial Times article underscores industry concerns that these rules could undermine the decentralized ethos of blockchain trading by compelling reliance on centralized brokers, potentially limiting investor control and transparency benefits inherent in onchain systems.

Legal commentators interpret the SEC’s approach as an effort to fit emerging tokenized securities within existing regulatory frameworks rather than creating novel rules tailored for DeFi. This may slow innovation by imposing traditional custody obligations on inherently decentralized trading models. Conversely, some observers note that the custody mandate could enhance market transparency and security by holding brokers accountable for safeguarding digital assets.

Why this matters

The SEC’s insistence on broker custody for tokenized stocks strikes at the core tension between traditional securities regulation and the decentralized nature of blockchain technology. At its foundation, onchain trading allows investors to hold and transfer assets directly, without intermediaries, which is a key driver of investor autonomy and operational transparency.

By requiring brokers to maintain custody, the SEC effectively reintroduces centralized control points into markets designed to function peer-to-peer. This has significant implications for how tokenized securities markets will evolve under U.S. securities laws. It may constrain the ability of DeFi platforms to operate fully autonomously and could shift market participants back toward traditional intermediaries, potentially diminishing some benefits of blockchain innovation.

From a regulatory perspective, the custody rule aligns with longstanding investor protection goals—ensuring brokers are responsible for safeguarding client assets against fraud and theft. This could improve security and accountability in tokenized securities markets, which remain nascent and complex.

However, the framework also raises broader questions about how securities laws adapt to new technologies. The requirement may slow the integration of decentralized finance within regulated markets by imposing rules designed for centralized intermediaries on inherently decentralized protocols. This regulatory tension reflects a wider challenge facing policymakers balancing innovation with investor protection.

What remains unclear

Despite the clarity around the SEC’s custody requirement in principle, several critical questions remain unanswered. The proposal does not specify how custody obligations will be enforced on blockchain platforms that inherently enable peer-to-peer transfers without intermediaries. The technical and operational mechanisms to reconcile custody rules with decentralized ledger functionality have yet to be detailed.

It is also unclear whether the custody rule will apply uniformly across all tokenized securities or if exceptions might exist for certain DeFi platforms or token types. The SEC’s stance on accommodating emerging decentralized custody solutions, such as smart contract-based asset management, has not been articulated.

Additionally, the potential impact of these custody requirements on the liquidity and market structure of tokenized stocks traded on decentralized exchanges remains unknown. There is limited data on how issuers of tokenized securities and DeFi platforms will respond in practice or adapt to the new regulatory environment.

Finally, the SEC proposal does not address how custody rules will intersect with the borderless and permissionless nature of blockchain trading, an issue that could complicate enforcement and cross-jurisdictional compliance.

What to watch next

Potential regulatory guidance or exemptions that might apply to decentralized finance platforms or specific categories of tokenized securities.
Industry responses and adaptations by tokenized securities issuers and DeFi platforms, including legal challenges or compliance strategies.
Developments in decentralized custody solutions or smart contract-based asset management that could influence future regulatory accommodation.
Data and analysis on market impacts, including liquidity and trading patterns, once the custody framework is enforced or finalized.

The SEC’s proposed custody framework for tokenized stocks encapsulates the broader regulatory challenge of integrating blockchain innovation with established securities laws. While aiming to protect investors, the approach raises unresolved questions about the compatibility of traditional custody rules with decentralized trading models. How these tensions will be resolved remains to be seen, with significant implications for the future of tokenized securities and decentralized finance.
