The Securities and Exchange Commission's recent push toward tokenized securities feels like a race to issue tokens on a blockchain. It is not. The real competition is over who controls custody, who operates the settlement rails, and which stablecoins institutions will trust to move capital onchain. Firms that win this game will own the pipes, not just the products. This article walks through why infrastructure—not issuance—determines winners, how stablecoins become the default settlement layer, and which companies are positioned to move fastest under evolving regulatory frameworks.
Why the SEC's tokenized-securities push is a custody and settlement game
Tokenizing a security means representing ownership of a stock, bond, or fund share as a digital token on a blockchain. Issuing the token is straightforward. The hard part is ensuring that token transfers are final, compliant, and legally binding in the eyes of regulators and counterparties. That requires a regulated custodian who holds the underlying asset, a transfer agent who maintains the cap table, and a settlement system that reconciles ownership changes in real time.
Traditional finance already has these roles. Broker-dealers custody assets. Clearing houses like the Depository Trust & Clearing Corporation (DTCC) settle trades. Transfer agents update shareholder records. Tokenization does not eliminate these functions—it shifts them onchain. The question is who gets licensed to perform custody and settlement in a tokenized world, and which blockchains regulators will recognize as valid settlement layers.
Think of it like mail service. You can write a letter (issue a token), but unless a postal system (custodian and settlement rail) delivers it and confirms receipt, the letter has no legal effect. The SEC cares more about who runs the postal system than who prints the envelopes.
The firms that control onchain custody and settlement own the infrastructure layer. Issuance is downstream.
Firms racing to become qualified custodians under SEC Rule 206(4)-2 or to register as transfer agents are positioning themselves to be the infrastructure backbone. That is where the durable advantage lies.
How stablecoins become the default rail for institutional settlement
When tokenized securities trade onchain, payment must happen onchain too. Institutions will not send fiat wire transfers and wait two days for settlement while a blockchain transaction confirms in seconds. They need a digital dollar that moves atomically with the security token. That digital dollar is a stablecoin—a token pegged 1:1 to the US dollar, backed by cash or short-term Treasuries.
Under proposed frameworks like the STABLE Act and regulatory guidance from the Office of the Comptroller of the Currency (OCC), only regulated stablecoin issuers with transparent reserves and regular attestations will be acceptable for institutional use. Unregulated or algorithmic stablecoins are off the table. This narrows the field to a handful of compliant issuers like Circle (USDC), Paxos (USDP), and potentially future offerings from firms like PayPal.
Stablecoins solve two problems at once. First, they enable atomic settlement—the security token and payment transfer in a single transaction, eliminating counterparty risk. Second, they let institutions stay onchain for the entire lifecycle of a trade, from execution to settlement to custody. No need to bridge back to traditional rails.
Here is how stablecoin-based settlement compares to traditional finance:
| Aspect | Traditional settlement | Stablecoin settlement |
|---|---|---|
| Settlement time | T+2 (two business days) | Near-instant (seconds) |
| Counterparty risk | Requires clearinghouse | Atomic swap (self-clearing) |
| Operational hours | Business days, market hours | 24/7/365 |
| Cross-border complexity | High (correspondent banks) | Low (same global rail) |
| Regulatory path | Established | Emerging (STABLE Act, OCC) |
Institutions want speed and finality. Stablecoins deliver both. Firms that issue or custody the dominant stablecoins become the settlement infrastructure for all tokenized securities trading on their platforms.
Coinbase, Robinhood, and Circle as infrastructure case studies
Coinbase holds a qualified custodian designation and operates Coinbase Prime, which custodies digital assets for institutions. It also owns a transfer agent license, letting it maintain shareholder records for tokenized securities. Coinbase supports USDC (issued by Circle, a former subsidiary) as a native settlement layer. This vertical integration means Coinbase can custody the security token, facilitate settlement in USDC, and maintain the cap table—all onchain, all in-house.
Robinhood has moved into crypto custody and is building relationships with institutional clients. In 2024, it acquired Bitstamp, a crypto exchange with European regulatory approvals, giving it custody infrastructure across jurisdictions. Robinhood does not issue its own stablecoin, so it relies on third-party rails like USDC. Its edge is retail distribution and a brokerage license that lets it offer tokenized securities alongside traditional stocks in a single interface. If the SEC permits tokenized equities, Robinhood's user-experience advantage could pull retail volume onchain.
Circle issues USDC, the second-largest stablecoin by market cap. It does not custody securities, but it provides the settlement rail everyone else uses. Circle's strategy is to be the plumbing layer. Every trade settled in USDC strengthens Circle's network effects and generates fee revenue. Circle is also pursuing a federal banking charter or payment-stablecoin license, which would make USDC the first fully federally regulated digital dollar. If granted, that status would make USDC the default choice for institutions that need regulatory certainty.
All three firms are building complementary moats. Coinbase owns the custody and transfer stack. Robinhood owns retail onramps. Circle owns the settlement currency. The firms that combine these functions—or partner tightly with the firms that do—will control the tokenized-securities value chain.
What traditional brokers gain and lose by competing on blockchain infrastructure
Traditional broker-dealers like Fidelity, Charles Schwab, and Interactive Brokers already custody trillions in assets. They have clearing relationships with the DTCC, regulatory licenses across jurisdictions, and decades of client trust. What they lack is native blockchain infrastructure. Moving securities onchain means rewriting custody systems, integrating with public or private blockchains, and deciding whether to issue proprietary stablecoins or rely on third-party ones.
The upside for traditional brokers is cost reduction. Blockchain settlement could cut clearing and custody costs by eliminating intermediaries and reducing reconciliation overhead. It also enables new products like fractional ownership of private assets, 24/7 trading, and programmable securities with embedded compliance logic. Brokers that move early could capture market share from crypto-native firms by offering tokenized products to their existing client base without requiring clients to leave familiar interfaces.
The downside is margin compression. If settlement happens onchain via atomic swaps and stablecoins, brokers lose float revenue from holding client cash and fee revenue from clearing services. They also face competition from crypto-native firms that are faster, cheaper, and designed for onchain workflows from day one. Traditional brokers must cannibalize their own business models to stay relevant.
Think of it like video rental stores in the early 2000s. Blockbuster owned the retail footprint and customer relationships, but streaming services owned the superior distribution technology. Brokers that treat blockchain as a backend upgrade—not a marketing gimmick—will integrate stablecoin settlement, custody tokenized assets in qualified wallets, and offer tokenized products alongside traditional ones. Brokers that wait risk becoming legacy infrastructure in a market that has moved onchain.
Timeline and regulatory uncertainty: which firms move fastest
The SEC's timeline for approving tokenized-securities frameworks is uncertain. Draft rules for transfer agents handling digital assets appeared in 2023, but final rules have not been published. The STABLE Act, which would require stablecoin issuers to obtain federal charters, has not passed Congress. The Financial Innovation and Technology for the 21st Century Act (FIT21), which would create clearer jurisdictional lines between the SEC and Commodity Futures Trading Commission (CFTC), remains in committee.
Despite this uncertainty, firms are moving. Coinbase has already custodied tokenized securities for private offerings. Circle has issued USDC under state money-transmission licenses and is applying for federal recognition. Robinhood has launched crypto wallets and is testing tokenized assets in sandbox environments. Traditional firms like Fidelity have launched Fidelity Digital Assets and custody Bitcoin for institutional clients, but they have not yet moved into tokenized equities.
The firms positioned to move fastest are those that already hold the licenses and infrastructure to operate under current rules, even if final frameworks are delayed. Coinbase can custody and settle using USDC today. Circle can issue stablecoins under existing state frameworks. Robinhood can offer tokenized assets to accredited investors under Reg D exemptions. Traditional brokers must wait for clearer rules before deploying blockchain infrastructure at scale.
Regulatory uncertainty favors firms that can operate in the gaps—those with licenses that straddle traditional finance and crypto, and those with stablecoins that are already compliant under current guidance. Speed comes from regulatory optionality, not from waiting for perfect clarity.
What this means for builders
If you are building onchain financial products, assume stablecoins will be the settlement layer and custodians will be the gatekeepers. Design systems that integrate with regulated stablecoin issuers, not algorithmic or offshore alternatives. Understand the difference between qualified custody and mere wallet services—institutions need the former. Build for composability with existing transfer agent and clearing systems. Full decentralization is a nonstarter for securities.
Watch which firms win custody licenses and transfer agent approvals. Those firms will become the infrastructure you integrate with or compete against. If you are building tooling for tokenized assets, partner with licensed custodians early. If you are building a stablecoin, pursue regulatory clarity aggressively—market dominance in institutional settlement goes to compliant issuers.
Focus on products that reduce friction for traditional institutions moving onchain. That means APIs for USDC settlement, custody wallets that meet SEC standards, and compliance automation that works with existing broker-dealer workflows. The firms that abstract complexity for incumbents will capture enterprise revenue.
Conclusion
The SEC's tokenized-securities push is not about who can mint the most tokens. It is about who controls the custody, settlement, and stablecoin infrastructure that institutions will rely on. Coinbase, Robinhood, and Circle are racing to own different layers of this stack—custody, distribution, and rails. Traditional brokers must decide whether to build competing infrastructure or partner with crypto-native firms. The winners will be the firms that move fastest under current rules, not those waiting for regulatory certainty. Infrastructure, not issuance, is the game. The firms that understand this will own the onchain economy.
