Morgan Stanley Launches Money Market Fund Dedicated to Stablecoin Reserves

Structured to meet GENIUS Act requirements — the third in a series of digital asset moves following Bitcoin ETF and tokenized Treasuries

Morgan Stanley Investment Management has launched a government money market fund called the 'Stablecoin Reserve Portfolio' designed to manage reserve assets for stablecoin issuers, Investing.com reported on the 23rd (local time). Operating under the ticker MSNXX, the fund is structured to satisfy the reserve investment requirements that would be imposed on stablecoin issuers under the GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins Act), currently under deliberation in the U.S. Congress. The fund targets a stable $1.00 net asset value (NAV), with daily liquidity and capital preservation as its primary objectives.

Portfolio Limited to Cash, Short-Term Treasuries, and Repos

The portfolio takes a conservative approach, investing exclusively in cash, U.S. Treasury securities with maturities of 93 days or less, and overnight repurchase agreements (repos) collateralized by Treasuries. While stablecoin issuers are the primary target investors, the fund is also accessible to retail and institutional investors.

"We are pleased to bring a new investment solution to market that directly addresses the needs of stablecoin issuers."

Morgan Stanley Investment Management's total assets under management (AUM) stood at $1.9 trillion as of March 31, 2026.

Third Digital Asset Move, Following Bitcoin ETF and Tokenized Treasuries

This launch is the latest in a series of digital asset initiatives by Morgan Stanley. Last month, the firm launched the Morgan Stanley Bitcoin Trust (MSBT), an exchange-traded product (ETP) tracking Bitcoin performance, with BNY Mellon serving as custodian for the trust. Earlier this year, Morgan Stanley joined BNY Mellon's money market fund tokenization initiative by introducing DAP Class shares into its Treasury portfolio. These shares are traded through BNY's digital platform and represented on-chain at equivalent value.

• Morgan Stanley Bitcoin Trust (MSBT) — Bitcoin performance-tracking ETP
• Tokenized Treasury Portfolio (DAP Class) — Participation in BNY Mellon's tokenization initiative
• Stablecoin Reserve Portfolio (MSNXX) — Money market fund dedicated to reserve management

The GENIUS Act Is Set to Reshape the Market Landscape

The significance of this fund launch is closely tied to the fate of the GENIUS Act. The legislation would require payment stablecoin issuers to maintain 100% reserves backed by liquid assets such as U.S. Treasuries and cash. If enacted, major stablecoin issuers including Tether (USDT) and Circle (USDC) would be required to allocate tens of billions of dollars in reserves into compliant fund structures. Morgan Stanley appears to have launched the fund preemptively — ahead of the bill's passage — to position itself as the go-to solution for this anticipated wave of demand.
