The US SEC is proposing an update to decades-old regulations to integrate public blockchains into the legal record-keeping of stock ownership. This historic shift could allow public networks like Ethereum to serve as official ledgers for securities.

What happened

In a landmark move for the financial industry, the U.S. Securities and Exchange Commission (SEC) has initiated a process to overhaul 50-year-old regulations governing Wall Street operations. The proposed changes aim to modernize how transfer agents record and validate stock ownership, explicitly allowing for the use of public blockchains (such as Ethereum as official ledgers of record.

While the draft rule maintains that a central transfer agent must retain ultimate control to ensure regulatory compliance and handle physical addresses, it paves the way for the underlying infrastructure to shift from private, siloed databases to transparent, distributed ledgers. This marks a significant shift in the SEC's stance toward public blockchain utility.

Technology context

The current stock market infrastructure relies on a system established in the 1970s, where institutions like the DTCC act as central repositories. When a trade occurs, it triggers a complex chain of manual and semi-automated reconciliations between brokers, clearinghouses, and transfer agents.

Public blockchains offer a decentralized alternative. By using smart contracts, shares can be "tokenized." In this model, the blockchain serves as the "golden source" of truth. Every transaction is timestamped, cryptographically secured, and visible to all authorized parties simultaneously, eliminating the need for multi-day settlement periods and complex reconciliation processes.

Why it matters

This regulatory update is a game-changer for the "Tokenization of Everything" narrative. By allowing public blockchains to decide legal ownership, the SEC is effectively integrating the efficiency of Web3 with the legal protections of traditional finance.

For the industry, this means a drastic reduction in operational risk. For retail investors, it could lead to 24/7 trading and near-instant settlement. Furthermore, it validates the security of public networks, moving them away from being viewed solely as speculative playgrounds to being recognized as robust financial infrastructure.

Key terms explained

Impact

In the short term, we will likely see major financial institutions launching pilot programs to issue traditional stocks as digital tokens on public chains. In the medium term, this could lead to a massive migration of capital. If public blockchains become the standard for stock ownership, the trillions of dollars currently held in the traditional stock market will become interoperable with the broader digital asset ecosystem, potentially fueling a new era of liquidity.

What's next

The proposal is currently open for public comment. Given the pro-innovation stance of the current administration under President Donald Trump, industry experts anticipate a favorable outcome. We are likely entering an era where the distinction between a "crypto asset" and a "traditional stock" begins to blur, as both will eventually reside on the same technological rails.

Frequently Asked Questions

What is the core of the SEC's new proposal?

The SEC is proposing to allow public blockchains to serve as the legal record for who owns a company's stock, updating 50-year-old rules.

Will this make stock trading faster?

Yes, using blockchain could enable near-instant (T+0) settlement, compared to the current one-day (T+1) waiting period.

Who will manage these blockchain records?

A regulated 'transfer agent' will still be responsible for the records, but they will use public blockchain technology as their primary ledger.

Does this mean stocks are becoming cryptocurrencies?

Not exactly. The underlying asset remains a stock with the same legal rights, but its digital representation and transfer method will use blockchain technology.

What are the benefits for regular investors?

Lower fees due to fewer intermediaries, 24/7 market access, and increased transparency regarding ownership and corporate actions.
