JPMorgan and BlackRock Build the Tokenized Reserve Layer Stablecoin Issuers May Need by 2027
Tokenized money market funds from JPMorgan and BlackRock are emerging as compliant, yield-bearing reserve vehicles under the GENIUS Act, potentially making them foundational infrastructure for U.S. stablecoin issuers.
JPMorgan and BlackRock are positioning tokenized government money market funds as the reserve infrastructure behind the next phase of institutional stablecoins. With U.S. licensing and reserve requirements approaching in 2027, the two asset managers may control the small pool of on-chain vehicles that can legally support compliant payment tokens.
JPMorgan’s Public-Market Shift
On May 13, 2026, J.P. Morgan Asset Management launched JLTXX, the JPMorgan OnChain Liquidity-Token Money Market Fund, on public Ethereum. The registered government money market fund invests exclusively in U.S. Treasury securities and overnight repurchase agreements. Each token represents one share at a $1.00 NAV, with daily dividend reinvestment.
JPMorgan committed an initial $100 million, with participation from Anchorage Digital. By October, tracking data from rwa.xyz placed the fund’s on-chain assets under management between approximately $677 million and $755 million. JLTXX operates through JPMorgan’s Kinexys Digital Assets platform, with subscriptions and redemptions available via Morgan Money in cash or stablecoins. The minimum investment is 1 million USDC.
JLTXX follows MONY, a December 2025 tokenized money market fund offered as a private placement to accredited investors. Its launch on public Ethereum is strategically important because the network already hosts much of the stablecoin ecosystem.
BlackRock and the Reserve-Asset Race
BlackRock entered the market earlier with BUIDL, launched in March 2024 through Securitize. The fund has reached approximately $2.25 billion in assets across nine chains, including Ethereum, Solana, and Avalanche.
Its more targeted product is BSTBL, the BlackRock Select Treasury Based Liquidity Fund, introduced on August 3, 2026. BSTBL is a tokenized share class of an existing money market fund with approximately $6.1 billion in assets. It was designed to qualify as a reserve asset for payment stablecoin issuers under the GENIUS Act.
The law permits reserves to include cash, demand deposits, short-term Treasury securities, overnight repurchase agreements, and registered government money market funds. It also allows the tokenized form of eligible assets when the tokenization complies with applicable law.
What This Means
Beginning January 18, 2027, U.S. payment stablecoin issuers will need an approved license and one-to-one reserves composed of eligible assets. Tokenized funds such as JLTXX and BSTBL could provide compliant, yield-bearing reserves that operate on-chain and settle continuously.
The GENIUS Act’s 40% concentration limit on reserves held with any single financial institution may require issuers to use both products. That creates a potentially concentrated reserve market rather than a broad competitive field.
For Solana, the significance is indirect but substantial: compliant reserve infrastructure could strengthen the stablecoin rails supporting payments, trading, and atomic settlement across public blockchains. JPMorgan and BlackRock are not merely participating in institutional crypto adoption; they may be building the reserve layer on which much of it depends.
