Morgan Stanley has outlined custody and operational arrangements for its proposed spot Bitcoin exchange-traded fund, naming Coinbase Custody and BNY as key service providers in a newly filed registration statement with the US Securities and Exchange Commission (SEC).
The proposed Morgan Stanley Bitcoin Trust would hold bitcoin directly rather than through derivatives or leverage, positioning the vehicle as a passive product designed to track the cryptocurrency’s market price.
The structure mirrors the framework used by other recently approved spot Bitcoin ETFs, signaling continued institutional standardization in digital asset products.
Institutional-Grade Custody Structure
Under the filing, Coinbase Custody and BNY would act as bitcoin custodians, responsible for safeguarding the trust’s digital assets and facilitating transfers tied to share creations and redemptions. The majority of holdings are expected to be stored in offline cold storage, with private keys kept disconnected from internet access to mitigate cybersecurity risks.
A limited portion of assets may be transferred to trading wallets to support liquidity during primary market activity. The trust disclosed that custody insurance coverage is maintained but shared across clients and may not cover all potential losses.
Beyond digital asset safekeeping, BNY would serve multiple operational roles, including administrator, transfer agent, and cash custodian. In that capacity, the bank would oversee accounting, shareholder recordkeeping, and cash management functions linked to ETF flows. The involvement of a global custody bank underscores how traditional financial institutions continue to anchor infrastructure supporting crypto-linked investment vehicles.
Benchmark and Competitive Landscape
The trust plans to calculate net asset value using the CoinDesk Bitcoin Benchmark 4PM New York Settlement Rate, which aggregates spot trading data from major exchanges to establish a daily reference price. Benchmark transparency and methodology have become central competitive factors as asset managers differentiate products in a growing field of spot Bitcoin ETFs.
Morgan Stanley’s filing adds to the intensifying competition among asset managers seeking exposure to digital assets through regulated structures. As fee compression and liquidity depth shape the ETF market, custody resilience, pricing benchmarks and institutional partnerships remain key determinants of investor adoption.
