BlackRock is lobbying U.S. regulators for more flexible stablecoin reserve rules, a move that could directly benefit its own BUIDL fund and the broader $160 billion market for tokenized assets.

BlackRock Inc. has formally urged the U.S. Office of the Comptroller of the Currency (OCC) to reconsider key provisions within the proposed GENIUS Act, arguing that a suggested 20% cap on tokenized reserve assets could stifle growth in the digital asset sector. In a comment letter, the world’s largest asset manager advocated for dropping the cap and expanding the range of permissible assets that can back stablecoins.
"A hard cap on the proportion of tokenized assets held in reserve could unnecessarily restrict the evolution of the digital asset ecosystem," the letter, summarized in a company filing, stated. BlackRock's position is that greater flexibility would allow for more efficient and scalable stablecoin models, ultimately benefiting institutional investors and the broader market by allowing funds like its own BUIDL to scale more effectively.
The debate centers on the composition of reserves that back stablecoins, which are digital tokens designed to maintain a stable value by referencing an external asset, typically a fiat currency like the U.S. dollar. The proposed 20% cap would limit the portion of a stablecoin's reserves that could be held in the form of other tokenized real-world assets (RWAs). BlackRock’s own BUIDL fund, which represents tokenized shares in a portfolio of U.S. Treasury bills, is a prime example of the type of asset that could be impacted. A restrictive cap could limit the use of BUIDL as a reserve asset for other stablecoins.
This push for more lenient reserve requirements comes as the total market for stablecoins hovers around $160 billion, according to data from DefiLlama. For BlackRock, a more favorable regulatory environment under the GENIUS Act would create a significant growth pathway for its tokenized products, boosting institutional confidence and investment in the space. Conversely, strict caps could hinder innovation and push activity to less-regulated jurisdictions.
BlackRock's commentary on the GENIUS Act, which focuses on the assets backing stablecoins, is unfolding alongside legislative progress on the separate but related CLARITY Act. The CLARITY Act deals with stablecoin yields and rewards, and recent reports indicate Senate negotiators have reached a compromise to restrict reward programs that mimic bank interest.
This development on the CLARITY Act is seen by some analysts as a positive sign, suggesting lawmakers are finding ways to balance innovation with financial stability. While the GENIUS Act addresses a different aspect of stablecoin regulation—its reserves—the progress on CLARITY creates a constructive backdrop for discussions with regulators like the OCC.
The regulatory push in the U.S. is not happening in a vacuum. Globally, financial giants are moving into the regulated digital asset space. In Hong Kong, for instance, both HSBC and Standard Chartered recently received stablecoin licenses from the Hong Kong Monetary Authority, marking a significant step for banks in the region.
This global trend underscores the importance of getting the U.S. regulatory framework right. As traditional financial institutions like JPMorgan, with its JPM Coin, and now BlackRock, with BUIDL, build out their digital asset offerings, the rules established by acts like GENIUS and CLARITY will determine whether the U.S. can maintain a competitive edge in the tokenization of finance.
