"A whole new set of competitors is emerging based on blockchain... stablecoins, tokenization, and smart contract platforms represent substitutes for deposit accounts, payment systems, and collateral management." — Jamie Dimon, CEO, JPMorgan Chase (April 2026 Shareholder Letter)
BlackRock, JPMorgan, and Morgan Stanley have each launched dedicated tokenized money market funds designed to capture the stablecoin reserve management market — a pool exceeding $320 billion in assets that must, under the GENIUS Act signed into law in 2025, be held in U.S. Treasuries, cash, and equivalent safe instruments.
JPMorgan deployed its OnChain Liquidity-Token Money Market Fund (JLTXX) on public Ethereum on May 13, 2026, seeding it with $100 million. BlackRock filed for two new vehicles on May 8, including the Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV), a blockchain-native fund with a $3 million minimum. Morgan Stanley launched its Stablecoin Reserves Portfolio (MSNXX) in April with a $10 million minimum and a 0.15% management fee. The three firms are competing for what amounts to the largest new fixed-income mandate since money market fund reform in 2016.
The stakes are substantial. Tether holds approximately $98.5 billion in U.S. Treasury bills. Circle backs $77 billion in USDC with more than 84% in government-backed obligations. Under the GENIUS Act, these issuers must park reserves in qualifying vehicles — creating an addressable market of roughly $250-280 billion in mandated safe-asset allocation.
The Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act), signed into law in 2025, created the first federal regulatory framework for payment stablecoins. On April 7, 2026, the FDIC Board of Directors approved a notice of proposed rulemaking to implement the Act's requirements.
Permissible reserve assets under the framework include:
The final clause — "tokenized forms of the foregoing" — opened a direct pipeline from Wall Street asset management into the crypto reserve stack. Money market funds that invest exclusively in qualifying assets now serve as eligible reserve instruments for stablecoin issuers, provided they maintain stable $1.00 NAV and daily liquidity.
Launched May 13, 2026 on public Ethereum. The fund invests exclusively in U.S. Treasury securities and overnight repurchase agreements collateralized by Treasuries and/or cash. JPMorgan seeded the fund with $100 million. Anchorage Digital participated at launch.
The fund's blockchain token address is publicly available (0x09864f52B035AE22eE739dFa5c748fA080D07bD8). Qualified investors subscribe through Morgan Money, JPMorgan's open-architecture trading and analytics platform. The fund's prospectus notes that compliance with GENIUS Act reserve requirements may produce lower yields than broader money market funds due to the constrained investment universe.
This is JPMorgan's second tokenized money market product on Ethereum, following My OnChain Net Yield Fund (MONY) launched in late 2025.
BlackRock filed with the SEC on May 8, 2026 for two new tokenized products:
BRSRV issues "OnChain Shares" through a permissioned framework on multiple public blockchains, with Securitize Transfer Agent LLC as the official transfer agent. Minimum investment: $3 million.
These products complement BUIDL, BlackRock's existing tokenized treasury fund that has grown to approximately $2.5 billion in AUM — a tenfold increase from its $200 million launch in March 2024. BUIDL accounts for roughly 40% of the total tokenized U.S. Treasury market.
Launched April 23, 2026 as part of the Morgan Stanley Institutional Liquidity Funds trust. The fund invests only in cash, U.S. Treasury bills with remaining maturities of 93 days or less, and overnight repurchase agreements collateralized by Treasuries.
Key terms: $10 million minimum investment, 0.15% management fee, stable $1.00 NAV target.
Unlike JPMorgan and BlackRock, Morgan Stanley's product does not run on blockchain rails. It is a traditional money market fund structured to meet GENIUS Act reserve requirements, accessible through conventional channels.
The stablecoin market reached an all-time high of $321 billion in total circulating supply as of April 2026, according to CoinDesk Research — the third consecutive monthly record. As of May 2026, the market has expanded to approximately $322 billion.
Market composition:
| Issuer | Circulating Supply | Market Share | |--------|-------------------|--------------| | Tether (USDT) | $183.7B | ~57% | | Circle (USDC) | $77B | ~24% | | Others | ~$61B | ~19% |
Tether and Circle collectively control approximately 81% of the market. Tether holds an estimated $98.5 billion in U.S. Treasury bills as of Q1 2025, making it one of the largest non-sovereign holders. Circle reports more than 84% of reserves in government-backed obligations.
Standard Chartered projects the stablecoin market could reach $2 trillion, noting the U.S. Treasury may need to boost T-Bill issuance to accommodate demand. At current growth rates (28% year-over-year for USDC), the reserve management mandate will expand proportionally.
The broader tokenized Treasury market provides context for why Wall Street is moving aggressively. According to data from multiple sources:
JPMorgan's own research, published May 21, 2026, concluded that tokenized money market funds still comprise only approximately 5% of the stablecoin universe despite their yield advantage. The bank expects this share to grow to 10-15% without regulatory changes — implying a $32-48 billion addressable market at current stablecoin supply levels.
| Feature | JPMorgan JLTXX | BlackRock BRSRV | Morgan Stanley MSNXX | |---------|---------------|-----------------|---------------------| | Blockchain-native | Yes (Ethereum) | Yes (Multi-chain) | No | | Minimum investment | Not disclosed | $3M | $10M | | Launch date | May 13, 2026 | Filed May 8, 2026 | April 23, 2026 | | Transfer agent | — | Securitize | Traditional | | GENIUS Act aligned | Yes | Yes | Yes | | Yield constraint | Yes (narrower universe) | Yes | Yes |
The blockchain-native versus traditional distinction matters. On-chain products allow stablecoin issuers to hold reserves as tokens on the same infrastructure where they issue stablecoins, potentially enabling real-time proof-of-reserves and composability with DeFi protocols. Traditional products require off-chain custody and reconciliation.
The emergence of three competing GENIUS Act-compliant reserve vehicles creates several dynamics:
Fee compression. Competition among asset managers for stablecoin reserve mandates — a pool with predictable, growing flows — will drive management fees toward commodity pricing. Morgan Stanley's 0.15% fee establishes an early benchmark.
Yield pass-through pressure. Stablecoin issuers currently retain most of the yield generated by reserves. Tether reported $13 billion in profit in 2024, largely from Treasury income. As reserve management becomes competitive and transparent, market pressure may force issuers to share yield with holders — a dynamic S&P Global has flagged as a financial stability consideration.
Concentration risk. If a small number of Wall Street funds absorb the majority of stablecoin reserves, the crypto ecosystem acquires new single points of failure in traditional finance. A liquidity event at a reserve fund could trigger stablecoin de-pegging.
Regulatory arbitrage narrowing. Tether, which operates outside the U.S., may face competitive pressure as U.S.-regulated alternatives (USDC, new bank-issued stablecoins) gain access to institutional-grade, compliant reserve infrastructure.
The GENIUS Act has effectively created a new fixed-income mandate worth hundreds of billions of dollars — and BlackRock, JPMorgan, and Morgan Stanley are positioning to manage it. The speed of entry (three products in 45 days) reflects a calculation that stablecoin reserve management represents a durable, growing revenue stream denominated in the safest assets on earth.
The competitive dynamics mirror the 1990s money market fund expansion, when institutional cash management shifted from bank deposits to fund products. The difference: this time, the funds themselves may run on the same blockchain infrastructure as their clients.
For stablecoin issuers, the arrival of institutional-grade reserve vehicles resolves one regulatory risk while creating another — dependency on a small number of traditional finance counterparties for a function that was previously managed internally.
The market will determine whether blockchain-native products (JPMorgan, BlackRock) or traditional structures (Morgan Stanley) win the majority of flows. Early evidence from the broader tokenized Treasury market, where on-chain products grew from $750 million to $16.2 billion in 26 months, suggests that blockchain-native deployment has a structural advantage in an industry built on blockchain rails.
