Moody’s gives top money market fund rating to Fidelity’s tokenized vehicle
Moody’s Ratings said on May 13, 2026 that it assigned its highest money market fund rating, Aaa-mf, to Fidelity International’s newly launched USD Digital Liquidity Fund SP. The fund is designed for institutional investors and operates as a digitally enabled investment vehicle, placing it at the intersection of traditional cash management and tokenized finance.
According to the rating rationale, the fund is structured as a segregated portfolio company domiciled in the Cayman Islands. It is managed by FIL Investments International, a subsidiary of FIL Limited. Moody’s said the Aaa-mf assessment reflects its view that the fund has a very strong ability to meet its objectives of capital preservation and liquidity. The agency also noted that the product follows the same investment strategy as the Aaa-mf-rated Fidelity Institutional Liquidity Fund plc, a low-volatility net asset value fund domiciled in Ireland.
Ethereum-based tokenization with off-chain ownership records
The fund issues tokenized shares that are initially recorded on the Ethereum public blockchain, with plans to expand to ZKsync at a later stage. However, legal ownership of the shares is not determined exclusively by blockchain records. Instead, title is maintained through an off-chain register administered by Apex Fund Services (Malta) Limited, which acts as transfer agent.
That structure is important to the rating analysis. Moody’s said the legal ownership framework operates independently of the blockchain layer, meaning investor rights do not depend on the functioning of a distributed ledger. In practical terms, the tokenization process changes how fund shares are represented and transferred, but it does not alter the nature of the underlying assets or the regulatory framework applicable to the fund. For institutional participants, this hybrid model may offer the efficiency benefits associated with blockchain-based settlement while preserving a more familiar legal and operational backbone.
Liquidity profile and short duration underpin the rating
Moody’s highlighted several portfolio characteristics that supported the top rating. The fund’s weighted average maturity remains below 60 days. It also maintains a liquidity profile in which at least 10% of assets mature daily and at least 30% mature weekly. Overnight deposits make up a significant share of the portfolio, helping keep market risk exposure low.
These features are central to money market fund analysis because they speak directly to a fund’s ability to preserve principal value and satisfy redemption requests under normal conditions. Moody’s framed the fund’s conservative duration management and ample short-dated liquidity as consistent with the standards expected of highly rated liquidity products designed for institutional use.
On-chain and off-chain subscriptions and redemptions
Another notable feature is the fund’s dual subscription and redemption setup. Institutional investors can subscribe to and redeem shares either on-chain through selected stablecoins or off-chain in U.S. dollars via traditional banking channels. Moody’s said this two-track structure enhances operational resilience, especially in scenarios involving blockchain outages or other disruptions in digital market infrastructure.
The product is designed to provide near-instant liquidity through 24/7 redemption availability, subject to available liquidity. If redemption requests submitted outside normal market hours cannot be met immediately, those requests are queued and processed once market hours resume. Moody’s noted that redeeming investors may face a fee when liquidity is provided outside market hours.
Crucially, the agency said that the use of a queueing mechanism or liquidity fee outside market hours does not weaken the fund’s assessment, provided those provisions are disclosed in the offering documentation. By contrast, a suspension of liquidity or the imposition of liquidity fees during market hours would be viewed more negatively and could lead to a downgrade.
Permissioned smart contracts aim to reduce operational risk
The smart contracts governing the tokenized fund are permissioned, meaning only approved participants can interact with the tokens. Moody’s said this design helps limit operational, governance, and regulatory risks associated with blockchain activity. That matters in an institutional context, where access controls, compliance procedures, and auditable participant frameworks are often as important as technological innovation itself.
Rather than embracing a fully open, permissionless model, the fund appears to be structured to fit within institutional standards for investor onboarding and transaction oversight. For rating purposes, this reduces uncertainty around who can hold or transfer fund interests and helps align the digital operating model with traditional compliance expectations.
Scale of Fidelity’s money market operations offers additional context
Moody’s added broader context by noting that FIL Investments International managed $34.5 billion in money market fund assets as of December 2025. The rating agency also observed that the fund may face a modest degree of shareholder concentration risk during its launch phase, though it expects that risk to decline as the vehicle grows and its investor base broadens.
The report also distinguished the Aaa-mf designation from a standard credit rating. It is a rating specifically for money market funds and reflects Moody’s view of investment quality for funds that primarily invest in short-term fixed-income instruments. Separately, FIL Limited carries a Baa1 Stable credit rating from Moody’s.
Why the rating matters for tokenized fund adoption
The decision is significant because it shows a major ratings agency is willing to extend its highest money market fund assessment to a tokenized structure, so long as the underlying investment strategy, legal framework, and liquidity profile remain robust. In this case, tokenization was not treated as a replacement for sound portfolio management but as an additional layer for share issuance, transfer, and access.
That distinction may be especially relevant as large asset managers experiment with bringing traditionally conservative products, such as liquidity funds and money market strategies, onto blockchain rails. The Fidelity product combines familiar institutional safeguards with new digital distribution mechanics, including public blockchain recording, permissioned smart contract controls, and stablecoin-based workflows.
More broadly, the rating arrives amid increasing attention to tokenized real-world assets and digital cash infrastructure. While the fund itself is targeted at institutional investors, the structure illustrates how legacy financial products are being adapted for round-the-clock, programmable environments without fully abandoning established legal registries, transfer agents, and cash management disciplines.
For the market, Moody’s assessment may serve as an indicator that tokenized fund products can achieve high standing when they preserve the core characteristics expected of traditional liquidity vehicles: short duration, strong liquidity buffers, transparent redemption mechanics, and a legal framework resilient to technical disruptions. In that sense, the rating is not only a milestone for Fidelity’s fund, but also a signal about how institutional tokenization may evolve in practice.
