Morgan Stanley Investment Management has introduced the Stablecoin Reserves Portfolio, a government money market fund created to serve the investment needs anticipated under the proposed GENIUS Act for stablecoin issuers.
The new portfolio is part of the Morgan Stanley Institutional Liquidity Funds trust and will trade under the ticker MSNXX. It is designed to accept required reserves that payment stablecoin issuers hold to back their outstanding stablecoins. The firm says the portfolio seeks to preserve capital, provide daily liquidity and produce income while maintaining a stable $1.00 net asset value.
According to the fund description, assets will be invested in three principal instruments: cash, U.S. Treasury securities with maturities of 93 days or less, and overnight repurchase agreements that are collateralized by Treasury securities. While Morgan Stanley expects shares to be held mainly by stablecoin issuers, the shares may also be available for purchase by other investors.
Fred McMullen, co-head of Global Liquidity at Morgan Stanley Investment Management, commented on the launch, saying, "We are pleased to deliver a new investment solution to the marketplace that seeks to address the needs of stablecoin issuers."
The rollout of MSNXX follows a string of recent digital asset initiatives by Morgan Stanley. In April, the firm launched the Morgan Stanley Bitcoin Trust, an exchange-traded product listed under the ticker MSBT that tracks the performance of bitcoin. The bank BNY provides custody services for that bitcoin trust and is identified in filings with the ticker BK on the New York Stock Exchange.
Earlier in the year, Morgan Stanley introduced DAP Class shares of its Treasury Securities Portfolio. Those shares were structured to participate in BNY's money market fund tokenization effort; they are available through BNY's digital platforms and have corresponding value represented through blockchain tokenization, according to the firm.
On the asset management side, Morgan Stanley Investment Management reported overseeing $1.9 trillion in assets under management or supervision as of March 31, 2026.
