Morgan Stanley has named Coinbase Custody and BNY Mellon as custodians in an updated filing for its proposed spot bitcoin exchange-traded fund. The amendment clarifies the bank’s operational partners and signals deeper institutional alignment with established crypto infrastructure providers.
According to a Tuesday amended S-1 registration statement filed with the Securities and Exchange Commission (SEC) (US), Coinbase will act as custodian and prime broker for the Morgan Stanley Bitcoin Trust. The Bank of New York Mellon (BNY) is listed as administrator, transfer agent, and cash custodian. Like other spot products, the trust is designed to track the price of bitcoin directly.
Why Custodian Selection Matters For ETF Approval?
Custody structure has been central to spot bitcoin ETF approvals since January 2024. Coinbase currently serves as primary custodian for most U.S. spot bitcoin ETFs, while Fidelity remains a notable exception with in-house custody. BlackRock’s iShares Bitcoin Trust (IBIT) became one of the fastest-growing ETFs on record after launch, reaching multiple assets under management milestones within months, according to public filings.
Analysts previously described Morgan Stanley’s bitcoin ETF filing as a “shocker,” given the bank’s historically limited crypto footprint. The firm ranks sixth in the U.S. by total assets and manages roughly 20 ETFs, yet only two carry the Morgan Stanley brand name, according to prior reporting. The bank has also filed for a Morgan Stanley Solana Trust, though that S-1 had not been updated at publication.
Earlier this year, Morgan Stanley appointed veteran executive Amy Oldenburg to lead an expanded digital asset strategy in a newly created role. Does the formal alignment with Coinbase and BNY suggest the bank is preparing for broader crypto product distribution across its wealth channels? The next inflection point will likely be regulatory feedback from the SEC and whether Morgan Stanley accelerates updates to its pending Solana trust filing.
