What are tokenized money market funds?

What exactly is a tokenized money market fund?

A money market fund is a long-established, regulated investment that holds short-term, high-quality instruments, typically government Treasury bills, repurchase agreements and similar cash-like assets. It is used by institutions and individuals as a place to hold cash that earns a modest yield while staying relatively liquid. A tokenized version keeps that same underlying fund but represents ownership of its shares as digital tokens on a blockchain.

In practice, the fund and its assets continue to sit within the ordinary regulatory perimeter, with a manager, a custodian for the securities and an administrator. What changes is the record of who owns the shares. Instead of existing only on a transfer agent's books, ownership is reflected on a distributed ledger, so shares can be transferred between eligible holders directly and, in some designs, at any hour rather than only during banking windows.

How do they work, and why have they grown?

When an eligible investor subscribes, they receive tokens that correspond to fund shares. The tokens can then be held in supported wallets and, where the rules permit, moved between approved parties. Yield generated by the underlying instruments is generally reflected either by increasing the token balance or by adjusting the token's value, depending on the product's design. Redemptions convert tokens back into cash under the fund's stated terms.

Growth has been rapid. Tokenized United States Treasury products expanded from under one billion dollars in early 2024 to well over ten billion dollars by 2026, with money market and Treasury strategies forming the largest slice of the wider tokenized real-world asset market. BlackRock's tokenized fund, known as BUIDL, launched in 2024 and became the largest single product in the category, expanding across several blockchains. Franklin Templeton's fund, known by the BENJI token, and products from managers such as Ondo and Circle sit alongside it. Interest has come from corporate treasuries, fintech platforms, family offices and some regulated allocators, several of whom use these instruments for collateral, liquidity management and faster settlement.

How do they differ from stablecoins?

The two are often confused because both are dollar-referenced tokens, but they are different instruments. A stablecoin is typically designed to hold a steady value, often one unit of a currency, and it usually pays no return to the person holding it. A tokenized money market fund is a regulated fund: the token represents a share in a pool of short-term assets, and the product seeks to pass through the yield those assets earn, after fees. Ownership of a fund share also brings the investor protections and disclosure that apply to that fund under its home regime.

Regulatory context has been developing in parallel. In the United States, the GENIUS Act of 2025 created a federal framework for payment stablecoins, and further legislation addressing which digital assets are treated as securities or commodities has been advancing. These are United States measures. Other countries, including members of the European Union and jurisdictions across Asia, apply their own rules, so the classification and permitted uses of both stablecoins and tokenized funds differ by country.

Where might they fit within family wealth structures?

For families and family offices, a tokenized money market fund is, at its core, a cash-management and liquidity instrument that happens to settle on a blockchain. Some hold digital assets that are volatile and want a yield-bearing, cash-like position that can move quickly, whether as a staging point between transactions or as collateral. Because these are fund shares rather than speculative tokens, they can appeal to holders seeking a more conservative on-chain exposure, though they still carry investment and technology risk.

Within regulated wealth structures, the exposure is generally accessed through professionally managed vehicles rather than by an individual holding tokens personally. A structure such as Private Placement Life Insurance, for example, holds investments through separate accounts and, in many cases, insurance dedicated funds, with an independent manager making the investment decisions. Whether a tokenized money market fund can sit inside such a structure depends on the carrier, the fund's own eligibility rules and the laws of the relevant jurisdiction. Treatment varies by country and is subject to local law.

What are the costs, limits and risks?

These are institutional instruments, and they carry ordinary fund costs, including management and administration fees that reduce the yield reaching the holder. Access is frequently restricted to qualified or professional investors, with minimum commitments that place many products outside a broad retail audience. Distribution is also uneven across borders: a fund available to one investor base may be closed to another, and cross-border marketing rules differ widely.

The risks are layered. There is the risk of the underlying fund, such as interest rate movements and the credit of its holdings, even though these strategies are generally conservative. There is technology and operational risk tied to the blockchain, the token standard and the custody of private keys. Redemption terms, secondary market depth and the legal treatment of token holders on an insolvency are still being tested and vary by product and jurisdiction. And the wider digital-asset environment is volatile, so a cash-like label on one instrument does not remove the volatility of a portfolio that also holds other crypto. As with any structure, the way an asset is held organises ownership; it does not change what the asset is.
