The SEC's "two-year rise to the chain" prophecy: When the entire US financial system enters a new era

Recently, SEC Chairman Paul Atkins made a bold prediction: within two years, the entire U.S. financial system—from stocks, government bonds, credit products, to real estate—could fully transition to a blockchain technology architecture. This is not a joke, but a reflection of a broad strategy driven by coordination among lawmakers, regulators, and major financial players.

If this prediction comes true, it will mark the biggest turning point in the U.S. financial markets since electronic exchanges emerged in the 1970s. The question is not “Will it happen?” but “How will this affect the entire financial world?”

Why “two years”? The legal framework is being built

Paul Atkins’s prediction is not based on imagination but on a series of clear steps. The “Project Crypto” initiative by the SEC, combined with two key bills—the GENIUS Act and the CLARITY Act—has created the necessary legal framework for this transition.

The GENIUS Act addresses digital currency issues. It allows the issuance of compliant stablecoins fully backed by reserves and transfers regulatory authority to banking regulators. The idea is simple: if cryptocurrencies are backed similarly to cash, they can serve as a medium of exchange on the chain.

The CLARITY Act clarifies legal ambiguities. It distinctly allocates jurisdiction between the SEC (securities) and the CFTC (commodities), defining which assets fall under which agency. Crypto platforms can now clearly see which regulatory framework applies to Bitcoin, and they can register as federally regulated intermediaries.

Beyond the SEC, other agencies are involved:

• OCC (Office of the Comptroller of the Currency, established 1973): Provides clearing and settlement services for derivatives. It is a natural bridge between traditional markets and blockchain markets.
• CFTC: The primary regulator of futures markets and derivatives brokers. Its coordination ensures tokenized futures contracts have a solid legal basis.

This multi-layered cooperation explains why the “two-year” prediction is not just fantasy—it results from careful planning.

Major players are already moving: from experimentation to deployment

As legal frameworks are being established, the world’s largest financial institutions have not hesitated. Each step they take is part of a larger picture of financial transformation.

BlackRock started by issuing a tokenized U.S. Treasury bond fund directly on Ethereum—a public chain. This is significant: it’s the first time a fund from the world’s largest asset manager appears on a public blockchain. It proves the technology works and paves the way for others to follow.

JPMorgan, meanwhile, rebranded its blockchain division as Kinexys and introduced atomic swaps. Banks can now exchange tokenized collateral for cash within hours instead of days. If you understand this, you see what’s happening: financial transactions are beginning to optimize for the blockchain world.

JPMorgan also tested JPMD (JPMorgan’s stablecoin) on the Base blockchain— a strategic move to explore the broader public blockchain ecosystem.

DTCC (Depository Trust & Clearing Corporation) is arguably the most strategic partner. By 2025, DTCC manages assets worth $100.3 trillion, including 1.44 million issued securities. It is the “central vault” and “general ledger” of the entire U.S. stock market.

In 2025, DTCC’s subsidiary DTC received a “no-objection letter” from the SEC— a landmark legal signal. This allows DTC to officially connect the traditional CUSIP system (securities identification) with the emerging tokenization infrastructure. It has begun testing tokenized Russell 1000 component stocks in a controlled environment.

When T+0 becomes reality: meaningful changes

If all this materializes, the U.S. financial system will undergo profound changes. These are not minor improvements but radical leaps in efficiency and operation.

Settlement speed: from T+2 to T+0 (or even seconds)

Currently, the standard settlement in U.S. stock markets is T+2 (two business days after trade). On blockchain, settlement can occur almost instantly—T+0 or even within seconds.

UBS demonstrated this by issuing digital bonds on the SDX platform, showing T+0 settlement capability. European Investment Bank also shortened digital bond settlement from five days to one day.

The benefits? Significantly reduced counterparty credit risk and operational risk. For time-sensitive transactions like repos (buy-sell agreements), reducing the holding period of securities is invaluable.

“Atomic delivery”: eliminating risk

On blockchain, “atomic delivery” means assets and payments occur simultaneously within a single, indivisible transaction. If the transaction doesn’t fully execute, it is canceled entirely. There’s no “delivery before payment” risk as in traditional finance.

Moreover, blockchain enables the release of “sleeping” capital. For example, collateral management could free over $100 billion annually trapped in lengthy processes.

Tokenized money market funds (TMMF): smart cash

Traditional money market funds (MMF) are considered “safe cash” in TradFi. But tokenized versions are entirely different.

BlackRock’s BUIDL fund is an example. It allows instant redemption via USDC (Circle’s stablecoin). Unlike traditional MMFs that require T+1 to withdraw, TMMFs can be redeemed immediately. Most importantly, when used as collateral, they continue earning interest until actually used—eliminating the “opportunity cost” of traditional collateral assets.

Full system transparency

Distributed ledgers record every transaction immutably, publicly, and verifiably. Smart contracts can automatically enforce compliance checks and corporate actions like dividends.

Regulators gain “God’s view”—real-time, comprehensive oversight of the entire system. This is powerful for risk management.

Risks not to overlook

Of course, not everything is rosy. This shift brings significant challenges.

Liquidity vs. capital efficiency

DTCC currently performs netting—aggregating millions of trades to reduce the actual cash and securities needed for transfer. This cuts capital needs by up to 98%.

But T+0 essentially involves real-time gross settlement (RTGS), which could undermine netting efficiency. Markets will need balanced solutions, such as “intraday repos”—netting over short windows while maintaining speed.

Privacy vs. transparency

Financial institutions rely on transaction privacy. But public chains like Ethereum are fully transparent. Large trades on Ethereum can be front-run—others see the transaction in the mempool and quickly create similar trades to exploit it.

Solutions include privacy-preserving tech like zero-knowledge proofs or operating on permissioned chains like JPMorgan’s Kinexys, where only approved members can participate.

Systemic risk amplification

The 24/7 market removes the “cooling-off” periods of traditional markets. Algorithmic trading or even margin calls via smart contracts could trigger cascading liquidations under stress, potentially amplifying systemic risk—similar to liquidity pressures during the UK LDI crisis in 2022.

DTCC: the bridge from old to new

DTCC is not resisting or opposing this trend. Instead, it is repositioning itself as a strategic bridge.

Managing $100.3 trillion in assets, DTC records ownership in the U.S. stock market. With the “no-objection letter” from the SEC to tokenize assets, it is effectively authorized to connect the old world (CUSIP identifiers) with the new (blockchain).

This has three key implications:

1. Tokenized stocks can now directly connect to DTC’s official infrastructure, rather than relying on isolated projects building their own systems.

2. Exchanges like Nasdaq can act as centralized exchanges (CEX), while DTC manages token contracts and allows token withdrawals—creating a system that truly promotes liquidity.

3. After nearly a decade of exploring distributed ledger technology for collateral management, DTC’s approval means it can finally put that knowledge into practical use.

Conclusion: Paul Atkins’s prediction is not far-fetched

The SEC chair’s “two-year on-chain” prediction is not a fanciful dream. It reflects a carefully crafted strategy supported by new legal frameworks, commitments from major financial institutions, and a foundational infrastructure (DTCC) ready to serve as a bridge.

If realized, over $50 trillion of the U.S. financial market will step into a new world—a programmable, transparent, fast, 24/7 operational environment. It would be the biggest breakthrough since the 1970s.

But like any prophecy, it carries significant challenges and risks. The question is not whether it can happen, but whether the U.S. financial system is prepared for such a transformation.
