Tokenized Funds of Fidelity and BlackRock Receive Top Moody’s Rating

In a significant development within the cryptocurrency landscape, Fidelity Investments and BlackRock’s tokenized money market funds have achieved the prestigious Aaa-mf rating from Moody’s. This accolade marks a notable advancement in the integration of blockchain technology with traditional financial products.

Understanding FILQ and BUIDL

The BlackRock USD Institutional Digital Liquidity Fund (BUIDL), launched in partnership with Securitize in 2024, initially operated solely on Ethereum. However, its reach has expanded to include other networks like Arbitrum and Polygon. Similarly, Fidelity Investments introduced its fund, the Fidelity International USD Digital Liquidity Fund (FILQ), on May 6, 2026, leveraging the Desygnate infrastructure by Sygnum.
Money market funds are exchange-traded products that invest in low-risk assets such as short-term U.S. Treasury bonds and repurchase agreements. These investments offer modest returns but provide asset protection against inflation and instability.

The Role of Blockchain Technology

Both FILQ and BUIDL distinguish themselves through their use of blockchain for issuing, accounting for, and redeeming shares. Tokens representing these products align with shares at a one-to-one ratio stored with trusted custodians. Shareholders can trade or exchange these tokens or use them as collateral within the blockchain realm without needing brokers.
In FILQ’s case, issuance and redemption occur using stablecoins. Blockchain integration facilitates round-the-clock transactions while enhancing transparency in share accounting.

Pioneering Efforts in Tokenization

BlackRock has been at the forefront of this innovative approach; however, other issuers have since joined this burgeoning field. JPMorgan Chase has already filed for a second tokenized money market fund tailored to stablecoin issuers.
As of May 12, 2026, the total volume of tokenized U.S. Treasury bonds reached $15.29 billion—a 6.25% growth over the past month—mainly facilitated by such funds alongside other products.

The Significance of Moody’s Aaa-mf Rating

Moody’s financial product rating scale spans nine levels from C to Aaa; however, money market funds are evaluated on six levels ranging from C-mf to Aaa-mf. The highest rating attained by FILQ and BUIDL signifies an extremely low risk level with an almost guaranteed full redemption likelihood.
In contrast to these top-rated products’ stability is Strategy’s stock holdings—the largest public holder of Bitcoin—which received a B- credit rating from S&P Global Ratings due to its speculative nature linked with limited liquidity risks.
This achievement underscores how integrating cutting-edge technology like blockchain into traditional finance can redefine security standards while opening new pathways toward more transparent investment opportunities across decentralized networks globally—ultimately shaping future trends within crypto markets worldwide!
