Delivery versus payment is the foundational principle of securities settlement: the transfer of a security from seller to buyer must occur simultaneously with the transfer of payment from buyer to seller. In the absence of DvP, one party to a securities transaction bears the risk that the other party defaults after delivery but before receipt of payment. The settlement crises of the 1960s paperwork crunch, the systemic near-failures of the 1987 crash, and the Lehman Brothers settlement disruptions of 2008 were all, in different ways, failures of the cash and securities legs to move in a coordinated, simultaneous manner.
Blockchain-native securities offer the possibility of perfect, atomic DvP: a smart contract that simultaneously releases the security token to the buyer and the payment token to the seller, with no window of exposure between delivery and payment. Realizing this possibility requires not just a tokenized security but a tokenized payment instrument — a digital representation of cash that can participate in the same atomic settlement transaction as the security token. This is the functional role that stablecoins increasingly play in tokenized securities markets, and it is why the stablecoin policy debate is inseparable from the future of tokenized securities settlement.
The Cash Leg Problem in Tokenized Securities
When a tokenized security changes hands, the settlement architecture must handle both the security leg (transfer of the token representing the asset) and the cash leg (transfer of the corresponding payment). In traditional securities markets, the cash leg travels through a complex chain of correspondent banks, clearing banks, and central bank settlement systems — a chain that introduces latency, counterparty exposure, and cost.
In blockchain-native securities markets, the security leg is handled efficiently by the smart contract infrastructure of the token itself. The cash leg is the bottleneck. If the cash payment for a tokenized security transaction must travel through traditional banking rails — wire transfers, ACH, SWIFT — the settlement latency of the cash leg prevents the atomic, simultaneous exchange that DvP requires. A tokenized security settled against a wire transfer is not truly DvP; it is a tokenized security settled against a delayed payment promise, with all the counterparty exposure that implies.
Three categories of digital cash instruments address this problem: bank-issued digital money (JP Morgan’s Kinexys, HSBC’s Everledger, BNY Mellon’s digital cash experiments), regulated stablecoins pegged to fiat currency (USDC, USDP, BUSD, and their successors), and central bank digital currencies (the hypothetical wholesale CBDC that the Federal Reserve has studied but not implemented). Each has different regulatory characteristics, trust properties, and adoption curves.
USDC and Circle’s Institutional Infrastructure
Circle’s USD Coin (USDC) has become the dominant regulated stablecoin in institutional digital securities markets, with a circulating supply exceeding $45 billion as of early 2026. USDC’s institutional adoption is not primarily driven by retail cryptocurrency trading — it is driven by institutional applications in digital securities settlement, cross-border payments, and DeFi protocol infrastructure.
Circle is licensed as a money transmitter in 49 US states and holds electronic money institution licenses in multiple international jurisdictions. Its monthly attestation reports, published by Grant Thornton, confirm that USDC reserves consist entirely of US Treasury securities with maturities under three months and cash held at regulated US financial institutions. This reserve composition — short-term Treasuries and bank cash — means that USDC is effectively backed by the same instruments as a government money market fund, but with the operational characteristics of a blockchain token: instant transfer, programmable in smart contracts, and non-custodial within the holder’s wallet.
In the tokenized securities context, USDC serves the cash leg of DvP settlement in several institutional applications. BlackRock’s BUIDL fund distributes daily accrued dividends to BUIDL token holders in USDC, delivered automatically to the investor’s wallet through a smart contract triggered by the fund’s on-chain accounting system. The BUIDL/USDC combination — a tokenized money market fund that distributes its yield in a tokenized money market instrument — represents a fully on-chain institutional finance stack that would have been theoretical as recently as 2022.
Securitize, in its role as BUIDL’s transfer agent and operational administrator, built the smart contract infrastructure that executes the daily USDC distribution. Investors holding BUIDL tokens receive USDC distributions proportional to their holdings, without any human intervention in the daily distribution process. The operational efficiency compared with traditional fund distribution mechanics — which involve daily reconciliation, transfer agent processing, and settlement through bank wires or ACH — is substantial.
JPMorgan Kinexys: Institutional Private Money at Scale
JPMorgan Chase’s Kinexys platform (rebranded from Onyx in late 2024) represents the most operationally significant deployment of bank-issued digital cash for securities settlement purposes. Kinexys processes in excess of $10 billion in daily transaction volume, primarily consisting of intraday repo transactions and cross-border institutional payments denominated in the JPM digital dollar.
The JPM digital dollar is a fundamentally different instrument from USDC, though both serve similar settlement functions. Where USDC is issued by a non-bank technology company (Circle) and backed by segregated reserves, the JPM digital dollar is a claim on JPMorgan Chase’s balance sheet — a deposit liability of one of the largest and most creditworthy financial institutions in the world. It is not a stablecoin in the consumer sense but rather a digitized bank deposit that can be programmed, transferred instantaneously, and used in smart contract settlement.
The Kinexys architecture uses a permissioned version of Ethereum (initially the Quorum variant, later migrated) to process institutional transactions between JPMorgan entities and approved counterparties. The permission model is by design: Kinexys is not a public, permissionless system but a closed network of institutional participants who have executed legal agreements with JPMorgan and completed the bank’s institutional KYC process.
Kinexys has processed intraday repo transactions for major institutional counterparties, enabling repo settlement and unwind within hours rather than overnight — a genuine operational improvement for collateral-intensive institutional portfolios. The integration of Kinexys with JPMorgan’s broader institutional banking infrastructure provides the custody, credit, and operational continuity that institutional counterparties require in ways that purely blockchain-native systems cannot yet replicate.

The GENIUS Act and Its Settlement Infrastructure Implications
The Guiding and Establishing National Innovation for US Stablecoins Act — the GENIUS Act — passed the Senate Banking Committee in March 2025 and represents the most significant stablecoin regulatory legislation to advance through Congress. The Act would establish a federal licensing framework for “payment stablecoin issuers,” requiring 1:1 backing with US dollars, Treasury securities, or Federal Reserve deposits; monthly public reserve attestations; and registration with either the OCC (for nationally chartered stablecoin issuers) or a state banking regulator (for state-chartered issuers).
The GENIUS Act’s implications for securities settlement stablecoins are significant. A federally licensed stablecoin issuer under the GENIUS Act framework would hold a regulatory status more clearly analogous to a narrow bank than to the current money transmitter licensing under which USDC and similar instruments operate. This enhanced regulatory standing would likely satisfy the counterparty risk requirements of major broker-dealers and custodians that currently operate under internal risk management constraints limiting their exposure to non-bank stablecoin issuers.
The most immediate securities settlement implication would be broader acceptance of regulated stablecoins as the cash leg of institutional DvP transactions. Under current institutional risk management frameworks, many prime brokers and custodians treat USDC as a non-bank liability subject to specific exposure limits. A GENIUS Act-licensed stablecoin from a federally chartered issuer would likely receive more favorable treatment, enabling larger-scale deployment of stablecoin settlement in institutional securities markets.
The Act also explicitly addresses the use of payment stablecoins in securities settlement contexts, providing that a GENIUS Act-compliant stablecoin used solely for the cash leg of a securities delivery versus payment transaction does not constitute the issuance of a new security under the Securities Act of 1933. This clarification addresses a latent legal uncertainty that has complicated the deployment of stablecoin settlement in registered securities contexts.
Federal Reserve Concerns: Private Money and Systemic Risk
The Federal Reserve has been the most consistently cautious voice in US stablecoin policy debates, and its concerns — while sometimes characterized as institutional protectionism — raise genuine macroprudential questions about the role of private money in securities settlement infrastructure.
The Fed’s core concern is straightforward: widely used stablecoins create the systemic risk profile of traditional bank money without the prudential regulation and deposit insurance backstops that make bank failures manageable. A rapid run on a major stablecoin — analogous to the money market fund runs of September 2008 — could create a disorderly unwinding of securities positions settled in that stablecoin, with cascading effects through the financial system.
This concern has informed the Fed’s advocacy for a wholesale central bank digital currency as the cash leg of future digital securities settlement systems. A wholesale CBDC — accessible only to regulated financial institutions, not retail users — would carry the full faith and credit of the US government, eliminating the run risk associated with privately issued stablecoins. The Federal Reserve Bank of New York’s Project Cedar, which explored wholesale CBDC mechanics, and the multi-bank Project Agora consortium, which examined tokenized deposit interoperability, both reflect the Fed’s preference for central bank money as the foundation of digital securities settlement.
The practical path to a Federal Reserve wholesale CBDC for securities settlement remains long. The Fed has repeatedly stated that implementing a CBDC would require Congressional authorization, and legislative consensus for a wholesale CBDC has been even harder to achieve than consensus for stablecoin regulation. In the interim, the market will continue to develop stablecoin-based settlement infrastructure that either anticipates a future CBDC transition or establishes sufficiently deep roots to persist alongside any eventual CBDC.
The On-Chain Treasury Market and Settlement Convergence
The convergence of tokenized Treasury securities (BUIDL, FOBXX, Ondo OUSG) with regulated stablecoins (USDC, USDP) in institutional portfolios creates an interesting structural dynamic. Institutional investors holding both tokenized Treasuries and USDC effectively hold two near-equivalent instruments — both backed by short-term Treasury securities, both instantaneously transferable on blockchain rails — but with different regulatory treatments, custody characteristics, and yield profiles.
USDC provides no yield to its holders (Circle retains the earnings on its reserve portfolio). Tokenized Treasury funds like BUIDL distribute their yield daily to token holders. From a portfolio management perspective, holding tokenized Treasuries rather than stablecoins provides the settlement functionality of stablecoin (instant blockchain transfer) plus the yield of money market instruments — a superior risk-adjusted return. This dynamic has driven significant growth in tokenized Treasury AUM as institutional investors optimize their on-chain cash management.
The practical question of settlement convergence — whether the on-chain securities market will ultimately settle in USDC, in bank-issued digital money like JPM Kinexys, in tokenized Treasuries that function as near-cash equivalents, or in a future wholesale CBDC — remains open. What is clear is that the settlement infrastructure question is being actively resolved by market participants rather than by regulators, with the regulatory framework following the market’s demonstrated technology preferences rather than leading them.
