Key receivers
Blackrock's BUIDL fund this week received a top AAA-mf rating from Moody's with $2.58 billion AUM.The AAA-mf rating tokens that certified Ethereum assets now meet the highest institutional security requirements.Following the BUIDL and Fidelity FILQ rankings, the $15 billion tokenized debt market expects further expansion.
Institutional Rating: Moody's has assigned an Aaa-mf rating to Blackrock's BUIDL.
The agency has assigned a AAA-mf rating to the fund, known as BUIDL, on or around May 13, 2026. This classification puts it at the same level of risk as the safest traditional money market instruments.
Working on Ethereum blockchainBUIDL has shown steady growth since its inception in March 2024. Moody's reports that the fund now manages approximately $2.58 billion in assets.
The rating indicates that the fund has a high potential to conserve capital and maintain liquidity. Moody's applied the methodology used for heritage funds to assess BUIDL's credit profile and operating structure.
Securitize, which holds tokens for the fund, confirmed the rating on social media. This update comes at the same time that Moody's rated Fidelity's Ethereum-based USD Liquidity Fund at its highest rating of Aaa-mf.
Fidelity's fund, known as FILQ, also received the highest rating. Both products offer institutional investors exposure to US Treasury products through blockchain-based tokens.
BUIDL invests in short-term US Treasuries, repurchase agreements and cash equivalents. It maintains a net asset value of $1 and pays daily production directly to investors' wallets.
The market for US government debt has grown dramatically, rising from $1 billion to $15 billion in two years. BlackRock Fund owns about 15% of this sector.
The AAA-mf rating is expected to help conservative institutions, such as pension funds, meet internal standards for asset safety. Most of these entities are prohibited from investing in unrated financial products.
Using blockchain, these funds allow for 24/7 settlement and leveraged production. This differs from traditional financial systems that typically rely on multi-day settlement cycles.
The total value of real world assets is about $31 billion. Moody's involvement suggests that the industry is moving toward greater institutional oversight.
Other companies in the tokenized treasury space may face pressure to seek similar standards. Moody's move sets a new benchmark for how digital currencies are evaluated by international agencies.
