Wall Street Goes Onchain Faster Than Its Rules Can Follow

• BlackRock-designed portfolios are moving onchain through Ondo.
• IBM is connecting banks to Swift’s 24/7 tokenized deposit ledger.
• The SEC is opening a temporary U.S. route for tokenized stock trading. 

A day after SEC Commissioner Hester Peirce warned that tokenized exposure to U.S. securities could develop overseas without a competitive domestic market, two pieces of financial infrastructure moved further onchain.

BlackRock-designed portfolio strategies became transferable tokens through Ondo Finance for eligible non-U.S. investors, while IBM connected bank infrastructure to Swift’s blockchain-based ledger for 24/7 tokenized deposit transactions.

The timing reveals a more complicated race than simply putting Wall Street assets on blockchain. Securities are becoming programmable, bank money is gaining always-on functionality, and U.S. regulators are beginning to open domestic trading infrastructure. The remaining friction increasingly sits between those systems: determining who can participate and what information they must surrender to do so.

The SEC Does Not Want Tokenized Wall Street Exported

Peirce’s September 23 speech came less than a week after the SEC introduced its Innovation Exemption for tokenized securities.

The five-year, conditional framework allows Tokenized Securities Venues to facilitate limited trading of tokenized National Market System stocks through permissioned automated market makers and liquidity pools. The SEC also requires the relevant smart contracts to be public and auditable and deployed on a public, permissionless distributed ledger.

SEC Chairman Paul Atkins described the exemption as a temporary bridge while the Commission considers longer-term rules for onchain trading. Peirce echoed that framing, but focused on the competitive consequence of moving too slowly. Her remarks represent her own views as a commissioner, rather than necessarily those of the SEC as a whole.

She argued that tokenization is coming and raised the prospect of foreign markets offering tokenized exposure to

American equities without an equivalent domestic option.

The following day provided a useful illustration of that concern.

Ondo Finance launched Intelligent Portfolios, with its first three products based on investment strategies developed by BlackRock specifically for Ondo. Each portfolio is represented by a single transferable onchain token, with the initial products available to eligible non-U.S. investors in permitted jurisdictions.

The distinction between the two companies matters.

BlackRock developed the strategies. Ondo determines how they are implemented and operates the tokenized products. Investors are therefore not buying BlackRock-issued blockchain ETFs.

That nuance changes the story from “BlackRock puts portfolios onchain” to something more interesting: traditional portfolio construction can now be distributed through blockchain infrastructure without the asset manager itself operating the tokenized product.

A Token Can Cross Platforms. Can Eligibility Follow It?

Ondo’s architecture creates a problem that is less visible inside a conventional brokerage account.

The portfolio token can potentially move between compatible blockchain applications rather than remaining locked inside the platform where the investment originated. Ondo says Intelligent Portfolios can be transferred and potentially integrated into lending, perpetual and other DeFi applications.

Every regulated interaction, however, still has to answer questions about the person on the other side.

That is where Peirce’s speech becomes more consequential than a standard tokenization address.

Much of her argument focused on financial surveillance and whether institutions need to repeatedly collect the underlying personal information used to establish a customer’s eligibility. She pointed toward attribute-based credentials and cryptographic techniques that could verify specific facts without exposing everything behind them.

The difference can be reduced to three practical checks:

• Investor status: prove that someone meets a required financial or regulatory classification without handing every platform the records used to establish it.
• Sanctions compliance: verify that an individual satisfies the relevant screening requirement without circulating another complete identity file.
• Age or jurisdiction: establish that a user meets a geographic or age condition while withholding unrelated personal information.

Zero-knowledge proofs are one possible mechanism. Instead of receiving the underlying data, a financial application could receive cryptographic evidence that a required statement is true.

Peirce is not proposing that Ondo adopt such a system, and her remarks should not be read as describing the architecture behind today’s portfolios.

The connection is broader.

Once a regulated financial product can move between platforms, verification also needs a way to operate across those boundaries. Otherwise, a portable asset may still encounter a new identity silo at every destination.

IBM and Swift Are Making Bank Money More Continuous

The same day brought a different piece of the infrastructure puzzle.

IBM Digital Asset Haven introduced beta connectivity to Swift’s blockchain-based shared ledger. Its ISO 20022 Messaging Adapter allows financial institutions to instruct tokenized deposit transactions using the messaging standard already embedded across global payment infrastructure.

That avoids asking banks to create an entirely separate operational language for blockchain payments.

Swift brings considerable distribution to the arrangement. Its network connects about 12,500 financial institutions across more than 200 markets, while its shared ledger was designed with more than 40 institutions.

Seventeen first movers are now piloting tokenized deposit transactions.

The 24/7 element needs one important qualification.

IBM says participating clients can move digital assets around the clock ahead of final settlement through existing systems. Swift’s blockchain ledger acts as an orchestration layer, while final settlement continues through established mechanisms such as real-time gross settlement systems and other existing financial-market infrastructure.

That is a very different proposition from replacing the banking system with blockchain.

IBM is instead building compatibility between the two.

Banks can retain ISO 20022 messaging, their own compliance processes and existing settlement infrastructure while adding a continuously available layer for tokenized deposits.

The architecture mirrors what is happening on the securities side: blockchain is being inserted into existing financial systems rather than forcing those systems to disappear.

The SEC Is Opening a Market, Not Just Allowing a Token

The Innovation Exemption addresses another bottleneck that often gets lost in tokenization headlines.

Representing a stock onchain does not automatically create a viable market for it.

Trading requires venues, liquidity, pricing, custody and rules determining who can interact with the security. The SEC’s exemption begins testing that market layer domestically.

That also creates a direct test of Peirce’s overseas concern.

The United States now has a temporary regulatory route for tokenized-stock venues. The question is whether firms use it to create meaningful domestic liquidity before international markets establish stronger network effects.

Tokenization Now Has to Prove Its Economic Value

The technical demonstrations are increasingly established.

A portfolio strategy can be packaged into one blockchain token. Commercial-bank deposits can move through a shared ledger outside conventional banking hours. Tokenized U.S. stocks can operate through permissioned

AMM infrastructure under temporary SEC relief.

The more difficult stage is proving that any of this materially improves finance.

For Ondo, that proof would appear beyond issuance. If its BlackRock-powered portfolios begin functioning as collateral, the relevant numbers will be borrowing liquidity, collateral haircuts and secondary-market depth.

Those metrics can show whether putting an entire allocation inside one transferable token creates capital efficiency that a conventional model portfolio cannot easily provide.

For IBM and Swift, the benchmark is different. Continuous tokenized deposit movement becomes economically important if it reduces prefunding requirements, idle liquidity or cross-border processing delays, rather than merely making transactions technically available on weekends.

And for the SEC, success is not the number of tokenized stocks approved for experimentation. It is whether the temporary framework produces liquid U.S.-based markets capable of competing with the overseas venues Peirce warned about.

Identity sits across all three.

If financial products become easier to move but every new platform still needs another complete copy of an investor’s personal information, part of the efficiency gained at the asset layer is lost at the compliance layer.

Attribute-based verification offers one possible alternative, but it will matter only if regulated institutions can use it while satisfying securities, sanctions and anti-money-laundering obligations.

That leaves tokenization with a harder benchmark than technological novelty.

The winners will not necessarily be the institutions that put the most assets onchain. They will be the ones that can demonstrate that doing so releases capital, shortens settlement frictions, creates deeper liquidity or reduces the amount of sensitive information that has to move alongside a transaction.

Those are outcomes financial markets can measure.
