The repurchase agreement market is the hydraulic system of global financial markets. Every business day, approximately $10 trillion in securities change hands temporarily in the U.S. repo market — financial institutions borrowing cash overnight by posting Treasury bonds, agency securities, and agency mortgage-backed securities as collateral, then repurchasing those securities the following morning plus interest. The market’s size reflects its centrality: repo is how banks fund their securities inventories, how money market funds invest their cash, how hedge funds finance long positions, and how the Federal Reserve implements monetary policy through its open market operations.
The repo market also has known inefficiencies that have persisted for decades because the costs of change are high and the incentives to bear those costs have been diffuse. Settlement is T+1 in the bilateral market and T+2 in some tri-party structures. Collateral moves during business hours only. Intraday liquidity is expensive because securities and cash legs are often settled sequentially rather than simultaneously. And the infrastructure supporting repo — the clearing banks, DTCC’s Fixed Income Clearing Corporation, and proprietary settlement systems — requires substantial operational overhead.
Tokenization offers a solution to each of these inefficiencies. Tokenized Treasuries settle instantly on blockchain networks. They can move 24 hours a day, 7 days a week. Their collateral eligibility status, ownership, and encumbrance can be verified programmatically in real time without relying on end-of-day reconciliation between multiple parties. And the smart contract infrastructure for programmable collateral management — automatic margin calls, automatic substitution, automatic payment of repo interest — can dramatically reduce the operational overhead of repo market participation.
How Repo Markets Work: The Mechanics That Tokenization Seeks to Improve
A conventional overnight repo transaction involves three main steps: the initial leg (the seller delivers securities to the buyer, the buyer delivers cash to the seller), the overnight holding period (the buyer holds the securities as collateral against the cash loan), and the closing leg (the seller repurchases the securities at the original price plus overnight interest).
The interest rate on this transaction — the repo rate — reflects the market clearing rate for overnight Treasury-collateralized cash lending. In normal conditions, the repo rate closely tracks the federal funds rate, providing a market mechanism that transmits Federal Reserve policy to short-term funding markets. When repo rates spike (as they did in September 2019, when overnight repo rates reached 10 percent), it signals a shortage of cash relative to collateral demand that can indicate broader liquidity stress.
The bilateral repo market — direct transactions between two counterparties — settles through the two parties’ clearing banks and DTCC’s FICC. Tri-party repo — where a clearing bank (BNY Mellon or JPMorgan Chase Bank) serves as intermediary, holding collateral and managing substitutions — handles the majority of institutional money market fund cash investment. The tri-party mechanism reduces operational burden for both parties but introduces clearing bank operational risk and dependency on business-hours settlement windows.
These structural features create real costs: a fund manager who receives cash proceeds from a bond sale at 3 PM cannot put that cash to work in tri-party repo until the following morning, forgoing one night of interest on perhaps hundreds of millions in uninvested cash. An institution that needs intraday liquidity must either maintain idle cash buffers or pay for intraday credit facilities — both expensive in terms of either foregone returns or explicit credit costs.
JPMorgan’s Tokenized Collateral Network: The Institutional Blueprint
JPMorgan’s Onyx Digital Assets platform has been the most ambitious institutional development in tokenized repo infrastructure. Launched in 2020 as the first bank-issued blockchain network specifically designed for institutional financial transactions, Onyx has processed over $900 billion in transactions through its JPM Coin institutional payment system and tokenized collateral network.
JPMorgan’s intraday repo product — conducted through Onyx — allows institutional clients to post tokenized money market fund shares as collateral for intraday liquidity facilities that are available outside conventional repo market hours. The mechanics: an institution holds tokenized MMF shares (effectively tokenized Treasury exposure) in a Onyx wallet. When intraday liquidity is needed, the institution can post those shares as collateral for a same-day cash advance, receive the cash within minutes, and unwind the position later in the trading day without waiting for conventional settlement infrastructure.
The economic benefit is substantial. Intraday liquidity that previously required either idle cash buffers or pre-arranged credit lines — both with significant capital costs — can instead be mobilized from existing Treasury holdings through a programmable collateral mechanism. JPMorgan’s initial estimate of the potential market for tokenized intraday liquidity is in the tens of billions of dollars per day, representing a meaningful fraction of the current bilateral repo market.
BlackRock has been particularly active in the Onyx ecosystem. The integration of BlackRock BUIDL with JPMorgan’s collateral network — allowing BUIDL tokens to serve as eligible repo collateral within the Onyx framework — represents the most complete instantiation of the tokenized collateral thesis: a major asset manager’s institutional money market product serving directly as collateral in the world’s largest bank’s repo infrastructure.
Goldman Sachs DAP: Repo Experiments at Scale
Goldman Sachs’ Digital Asset Platform has pursued a complementary approach to tokenized repo, focusing on securities lending and repo transactions where the primary innovation is blockchain-native settlement rather than intraday liquidity extension.
Goldman’s DAP repo transactions have included bilateral repo agreements where both the securities leg and the cash leg are settled on-chain, eliminating the sequential settlement risk that exists in conventional repo when one leg settles before the other. This simultaneous settlement — known as delivery versus payment (DvP) in conventional securities terminology — is a standard feature of many financial markets but has been difficult to achieve in repo because securities and cash move through separate infrastructure networks.
Goldman’s DAP tokenized bond issuances — including the $100 million digital green bond for the European Investment Bank in 2021 and subsequent transactions with the Hong Kong government and other issuers — have demonstrated the technical feasibility of on-chain DvP settlement for institutional securities. The repo applications of this infrastructure represent a logical extension: if bond ownership can be transferred on-chain with simultaneous cash settlement, repo transactions using those bonds as collateral can follow the same settlement mechanism.
Goldman’s more cautious public posture on blockchain development relative to JPMorgan reflects a different strategic calculation about the pace of institutional adoption rather than a different technical assessment. Both firms have invested heavily in blockchain infrastructure; Goldman’s expression of that investment has been more selective in client-facing product development.
Broadridge DLR: The Institutional Record
Broadridge Financial Solutions’ Distributed Ledger Repo (DLR) platform has processed the largest documented tokenized repo volumes of any institutional blockchain application. In 2023, Broadridge set a single-day record of $384 billion in tokenized repo transactions through the DLR platform — a figure that represents approximately 4 percent of total daily U.S. repo market volume and nearly 20 percent of the tri-party repo market.
The DLR platform’s architecture differs from blockchain-based approaches: Broadridge uses a permissioned distributed ledger rather than a public blockchain, with participating institutions (BNY Mellon, JPMorgan, Société Générale, Credit Suisse, and others) as authorized nodes. The platform automates collateral allocation, substitution, and valuation across the participants’ portfolios, with real-time visibility into collateral positions that replaces the end-of-day reconciliation process in conventional repo.
The $384 billion record demonstrates that distributed ledger technology for institutional repo is not theoretical — it is operational at a scale that represents a meaningful fraction of the total repo market. Broadridge’s estimate is that DLR reduces average repo settlement times from approximately 15 minutes to under 5 minutes, and reduces the operational cost of collateral management by approximately 35 percent for participating institutions.
The DLR platform’s permissioned architecture means it does not interact with public blockchain tokenized assets like BUIDL or OUSG — it is a closed network among Broadridge’s institutional clients. But the operational proof of concept it provides for tokenized repo infrastructure applies directly to the public blockchain tokenized Treasury use case, demonstrating that institutional appetite for this kind of operational improvement is real and large.
BUIDL as DeFi Collateral: The Aave V3 Integration
The most novel development in tokenized collateral is the acceptance of BlackRock BUIDL as collateral within Aave V3’s institutional lending market — a development that connects the world’s largest asset manager’s institutional Treasury product to the world’s largest decentralized lending protocol.
Aave V3’s governance approved BUIDL as eligible collateral in early 2025, with specific parameters: a loan-to-value ratio of 75 percent, a liquidation threshold of 80 percent, and a liquidation penalty of 5 percent. These parameters reflect the high credit quality of BUIDL’s Treasury holdings (setting the LTV high) while accounting for the redemption mechanics and potential price deviation risk in stress scenarios (requiring overcollateralization).
The practical implication: an institution holding $100 million in BUIDL can borrow up to $75 million in USDC against those holdings within Aave V3, without selling the BUIDL position. The BUIDL continues to earn Treasury yield during the loan period, while the borrowed USDC can be deployed in additional yield strategies — creating a leveraged yield position that earns Treasury returns on the full $100 million while paying Aave borrowing rates on the $75 million loan.
This mechanism — using tokenized government securities as collateral for DeFi stablecoin borrowing — is functionally analogous to repo: the BUIDL holder temporarily monetizes their security position for cash, paying an interest rate for the borrowed liquidity, while retaining the underlying security exposure. The DeFi implementation has specific advantages over conventional repo: no counterparty credit risk (the smart contract enforces the collateral arrangement without requiring trust in a counterparty), 24/7 availability, and programmatic liquidation that eliminates the manual margin call process of conventional repo.
Tri-Party Infrastructure: BNY Mellon and the Legacy System
The conventional tri-party repo infrastructure — where BNY Mellon and JPMorgan Chase Bank serve as clearing banks for the majority of institutional repo transactions — processes approximately $4 trillion per day in tri-party repo, primarily between broker-dealers and money market funds. Both clearing banks have developed their own digital asset and tokenization capabilities, but the pace of integration between their legacy tri-party infrastructure and emerging tokenized collateral systems reflects the complexity of changing systems at this scale.
BNY Mellon’s Digital Asset Custody platform and JPMorgan’s Onyx represent both firms’ investments in positioning for the tokenized collateral market. BNY Mellon’s particular strategic interest stems from its central role as the primary custodian for institutional tokenized Treasury funds — including custody of BUIDL’s underlying Treasury portfolio — which positions it at the nexus of conventional custody and emerging tokenized collateral infrastructure.

The 24/7 Repo Implication: Structural Impact on Money Markets
The most consequential long-term implication of tokenized repo infrastructure is the potential for 24/7 repo market operation. Conventional repo markets operate during business hours in their primary jurisdictions — the U.S. tri-party market is functionally available from approximately 7 AM to 6 PM Eastern time, Monday through Friday. Outside those hours, no conventional repo can be initiated or closed.
This temporal constraint has significant economic implications. Governments and financial institutions in Asia-Pacific time zones cannot use U.S. Treasuries as overnight repo collateral during their business hours without accepting settlement risk from the lag to U.S. market opening. Institutional investors receiving large cash flows outside U.S. business hours — from securities sales, bond maturities, or dividend payments — hold idle cash overnight rather than deploying it in collateralized lending.
A tokenized repo market operating 24/7 on blockchain infrastructure would eliminate this temporal constraint. Asian central banks could repo their U.S. Treasury reserves during Asian business hours. European pension funds could roll repo positions during their business day rather than pre-positioning in the U.S. market. Corporate treasurers could put overnight cash to work in real time rather than through end-of-day batch processing.
The interest income impact alone is meaningful: the Federal Reserve estimates that financial institutions collectively hold over $500 billion in overnight cash balances that earn below-repo rates because of settlement timing constraints. Eliminating these constraints through 24/7 tokenized repo would reallocate tens of billions of dollars annually from idle cash into collateralized overnight lending — improving the efficiency of short-term capital markets and narrowing the spread between the federal funds rate and overnight Treasury yields.
Federal Reserve engagement with this possibility has been cautious. The Fed’s wholesale CBDC research program — Project Hamilton (with MIT) and subsequent explorations — is explicitly oriented toward the settlement problem that makes 24/7 repo technically feasible in private blockchain infrastructure but still reliant on conventional cash settlement. A wholesale CBDC that could settle repo cash legs in real time across jurisdictions and time zones would be the final piece of the 24/7 repo infrastructure puzzle — and the Fed’s willingness to issue such an instrument remains the central policy uncertainty for the full realization of the tokenized collateral market.
Tokenized collateral represents the use case where the efficiency benefits of blockchain technology are most directly measurable in basis points — the currency of money markets. The repo market’s existing scale, institutional familiarity, and quantifiable inefficiencies make it the natural first frontier for tokenization to demonstrate its full institutional value, before the more complex questions of tokenized equity, real estate, and alternative investments are resolved.
