Morgan Stanley Chooses Coinbase and BNY Mellon as Bitcoin ETF Custodial Partners
The Wall Street banking giant's latest move arrives amid positive inflows for BTC exchange-traded products, following its recent SEC filings for digital asset funds covering Bitcoin, Ethereum, and Solana.
Banking powerhouse Morgan Stanley has designated crypto exchange Coinbase alongside Bank of New York (BNY) Mellon, a worldwide financial services corporation, to serve as custodial partners for its Bitcoin Trust Exchange-Traded Fund (ETF), as disclosed in a Wednesday submission to the US Securities and Exchange Commission (SEC).
According to the SEC documentation for Morgan Stanley Bitcoin Trust, the designated custodians will maintain the entirety of the fund's Bitcoin (BTC) holdings in cold storage—offline storage methods for Bitcoin private keys—with select BTC quantities periodically transferred to internet-connected hot wallets when needed for fund creation and redemption activities. The filing stated:
"The Bitcoin custodians are chartered as a New York state bank, in the case of BNY, and as a New York state limited liability trust company, in the case of Coinbase custodian. The Bitcoin custodians provide custody and trade execution services for digital assets."
In January, Morgan Stanley submitted SEC registration applications for spot Bitcoin and Solana (SOL) ETFs. These investment products are both passive vehicles designed to hold and mirror the price movements of their respective underlying cryptocurrency assets.
The ETF launch represents expanding institutional embrace of cryptocurrency despite an ongoing market correction that has pushed BTC approximately 42% below its peak of roughly $126,000. In the past several days, flows into Bitcoin ETF products have reversed direction, highlighted by BlackRock's spot Bitcoin ETF recording $322 million in inflows on Tuesday, which counterbalanced withdrawals from competing products offered by Fidelity and Grayscale.
These recent inflows push the current week's cumulative total to $683.3 million, coming on the heels of the previous week's $787.3 million in inflows—marking the initial positive week following five straight weeks of withdrawals that amounted to almost $4 billion.
ETF will give Morgan Stanley crypto clout, even if it isn't a "blockbuster" hit
Arriving roughly two years following the initial launch of Bitcoin ETFs in United States markets, this new investment product will establish Morgan Stanley's presence in the cryptocurrency space and deliver value to the firm regardless of whether it achieves performance levels comparable to industry leaders such as BlackRock's iShares Bitcoin Trust, according to Jeff Park, advisor to digital asset management firm BitWise.
During the firm's January earnings call covering the fourth quarter of 2025, chairman and CEO Ted Pick informed analysts that the Wall Street financial institution was "well positioned now in the crypto and tokenized asset space," further noting that "there is a lot for us to do there."
Introducing an ETF product solidifies the firm's position within the cryptocurrency industry, simultaneously providing the company with the ability to attract premier talent from the digital asset sector to develop additional initiatives such as tokenized real-world asset (RWA) trading platforms, Park explained.
On the flip side, a Bitcoin ETF introduction from a prominent financial services institution also represents a "bullish" development for the broader cryptocurrency sector, as it demonstrates significant "untapped" demand for digital assets remains in the marketplace, he further noted.
"It means the market is much bigger than even crypto professionals anticipated, especially to reach new customers," he said.
