How they work, why institutions use them and the EU route for fund managers. section: "Home > Uncategorized > Tokenized Money Market Funds: What They Are and Why Institutions Use Them" --- # Tokenized Money Market Funds: What They Are and Why Institutions Use Them A tokenized money market fund is a regulated money market fund whose shares are recorded and transferred as tokens on a blockchain. The portfolio does not change: short-term government paper, repurchase agreements and cash. What changes is the share register, which moves onto DLT rails, and with it the speed at which investors can move, pledge or settle fund shares. These vehicles matter to issuers and fund managers for a simple reason. They are the most tested case of fund tokenization to date, run by the largest asset managers in the world, and they show which benefits are real and which remain marketing. ## How a tokenized money market fund works The mechanics stay close to a traditional fund. Investors subscribe and redeem against the fund at net asset value. A transfer agent keeps the register of shareholders. The difference is that the register lives on a blockchain, each share is represented by a token, and transfers between whitelisted investors settle on-chain instead of through the transfer agent’s queue. Income handling adapts to the rail. Several of these funds accrue yield daily and pay it out as new tokens, so a treasury desk sees its position grow on-chain rather than waiting for a monthly statement. Custody of the underlying assets stays with a conventional custodian bank. ## Two verified examples **BlackRock BUIDL.** The BlackRock USD Institutional Digital Liquidity Fund launched in March 2024 as BlackRock’s first tokenized fund issued on a public blockchain, with tokenization and transfer agency services provided by Securitize. It invests in cash, US Treasury bills and repurchase agreements, and it passed 1 billion dollars in assets in March 2025, according to Securitize. It is open to qualified investors, not to the retail public. **Franklin Templeton FOBXX.** The Franklin OnChain U.S. Government Money Fund, whose shares are represented by BENJI tokens, is a US-registered money market fund that uses a public blockchain as its system of record for transactions and share ownership. It has operated since 2021 and now runs across several public networks. Both examples are US vehicles under US securities law. They prove the operating model works at scale. They do not, by themselves, answer the European legal questions, which we cover below. ## Why institutions use them | Use case | What the token rail adds | | --- | --- | | On-chain treasury management | Idle stablecoin or cash balances earn money market yield without leaving the chain environment. | | Collateral mobility | Fund tokens can be posted and moved as collateral between whitelisted counterparties at any hour, any day. | | Settlement asset | A yield-bearing, regulated alternative to stablecoins for settling trades between institutions. | | Faster transfers | Peer-to-peer transfers between approved investors settle in near real time instead of transfer-agent cycles. | A related label you will meet is “tokenized treasuries”. It covers this category plus products that tokenize direct exposure to Treasury bills outside a money market fund wrapper. The fund wrapper adds diversification rules, professional management and a regulated NAV; direct products trade that away for simplicity. ## Honest limits - **Access is gated.** The flagship funds serve qualified or institutional investors. The 24/7 transferability exists inside a whitelist, not on an open market. - **Redemption is still a fund process.** Tokens move around the clock; getting cash out of the fund follows the fund’s redemption terms. - **The token depends on the register.** The legal position of the investor rests on the transfer agent and the register arrangements, not on the token alone. - **Yield is money market yield.** These are cash management tools. Nothing about the rail changes the return profile of short-term government paper. ## The EU angle for fund managers Units and shares of collective investment undertakings are financial instruments under EU law. A tokenized fund share therefore stays inside securities and fund regulation, and outside MiCA, which expressly excludes crypto-assets that qualify as financial instruments ([Directive 2014/65/EU](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32014L0065), Annex I, Section C; [Regulation (EU) 2023/1114](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32023R1114), art. 2.4). That means a European manager keeps its existing authorisation and fund rules, and adds one new question: who keeps the legally valid register when shares are represented on DLT. In Spain, that role belongs to an ERIR, the registration entity created by art. 8 of Law 6/2023 and developed in Royal Decree 814/2023; the first ERIR, URSUS-3 Capital, A.V., was authorised in November 2024 ([Ley 6/2023](https://www.boe.es/eli/es/l/2023/03/17/6/con); [RD 814/2023](https://www.boe.es/buscar/act.php?id=BOE-A-2023-22764)). Money market funds in the EU also carry their own product rules on eligible assets, liquidity and valuation under [Regulation (EU) 2017/1131 on money market funds](https://eur-lex.europa.eu/eli/reg/2017/1131/oj), separate from the tokenization question. Tokenizing the register does not touch those obligations.

For a European manager, the decision is not whether the model works. It is whether your investor base values on-chain transferability enough to justify a DLT register, and which Member State figure, such as the Spanish ERIR, will keep that register legally valid. **Weighing a tokenized share class or a DLT register for your fund range?** Run the [2-minute issuance assessment](https://hokenfi.com/en/issuance-assessment/) or [request a proposal](https://hokenfi.com/en/request-a-proposal/). *This content is educational.
