Investment banking giant Morgan Stanley has made a quiet and significant shift to stablecoins, expanding its footprint in the digital asset industry.
The firm’s investment management arm, MSIM, has announced the launch of the Stablecoin Reserves Portfolio – a sovereign money market fund designed for issuers of stablecoins who need a regulated, secure place to store the reserves that back their tokenized versions of fiat currencies.
Here is the simple version of what the fund is designed to do.
When a company issues a stablecoin – a digital token pegged to the US dollar or other fiat currencies – it must hold real dollars in reserve to back each token created. Think of it as a guarantee: for every blockchain-based dollar issued, a real dollar must exist somewhere safe and accessible. Morgan Stanley’s new fund is that place.
The fund (MSNXX) only invests in the safest and most liquid instruments, such as US Treasury bonds, which are short-term loans to the US government. The return on these is largely considered to be the closest to a risk-free return. It also invests in repurchase agreements, or repos, which are overnight loans backed by the same government securities. Both instruments are designed to preserve capital.
The fund aims for a net asset value of $1, which means that every dollar deposited into the fund is worth exactly the same when withdrawn, helping to circumvent price fluctuations. It is different from routine funds where the value of your investment rises and falls daily. In addition, the fund offers daily liquidity, which means investors can withdraw their money on any weekday without waiting or penalty.
“We are pleased to deliver a new investment solution to the marketplace that seeks to meet the needs of stablecoin issuers,” Fred McMullen, co-head of global liquidity, Morgan Stanley Investment Management, said in the press release.
“The significant increase in stablecoin issuers as well as the growing number of assets in stablecoins represent an evolving part of the marketplace that is ripe for future growth,” he added.
Stablecoins have seen their market capitalization grow multiple times in recent years, reaching $316 billion, with dollar-pegged tokens such as Tether and USDC making up the majority of the total. While initially primarily used to facilitate crypto trading, stablecoins have gradually expanded into real-world use cases, including money transfers and cross-border capital transfers.
The sector therefore stands out as perhaps the only one with a clear real-world application, while the wider market remains largely speculative.
Why now?
Morgan Stanley’s new fund comes as the GENUIS ACT – Guiding and Establishing National Innovation for US Stablecoins Act – is currently moving through Congress. If passed, it would legally require stablecoin issuers to back their tokens with high-quality liquid assets such as Treasury bills and cash-like instruments. And these must be kept in regulated vehicles.
The fund is therefore positioned to take up reserve management activities before it becomes mandatory.
Part of a larger push
Morgan Stanley Investment Management recently launched the Morgan Stanley Bitcoin Trust (MSBT), a cryptocurrency ETP designed to track bitcoin, with BNY Mellon providing custody and fund management services.
It also introduced tokenized DAP class shares in its institutional liquidity fund Treasury Securities Portfolio in partnership with BNY, enabling blockchain-based mirrored records. At the same time, BNY keeps the official books and records.
“We have actively engaged across the industry to develop the capability to offer digital asset-related liquidity solutions,” McMullen said. “Although still in the early stages, these latest product launches signify our commitment to developing relevant, timely solutions that can meet changing investor needs in an increasingly digital marketplace.”
