J.P. Morgan Selects BNY Mellon and Coinbase as Bitcoin ETF Custodians

J.P. Morgan has named BNY Mellon and Coinbase Custody Trust Company as custodians for its proposed Bitcoin Trust, a move that mirrors strategies used by other major asset managers like BlackRock according to reports. This structure is part of the bank's effort to launch a spot Bitcoin ETF, which it first filed for in January 2026. The amended S-1 filing outlines how these custodians will safeguard the fund's assets, with a focus on regulatory compliance and investor confidence as detailed.

Morgan Stanley is also following a similar approach. It disclosed plans to use BNY Mellon and Coinbase for its own Bitcoin Trust, a spot ETF that will directly hold Bitcoin according to disclosures. The firm's digital assets head has indicated that it plans to build in-house capabilities for custody, trading, and lending services in the future as stated.

Both banks are leveraging existing infrastructure in the digital asset space to meet stringent regulatory requirements. BNY Mellon has already served as a custodian for other Bitcoin ETFs, including BlackRock's iShares Bitcoin Trust according to data.

Why Is This Custody Structure Significant?

The choice of custodians reflects a growing trend among major asset managers to rely on institutional-grade custody solutions. BlackRock's iShares Bitcoin Trust originally used Coinbase as its sole custodian before adding Anchorage Digital as a second custodian in April 2025 according to reports. This redundancy helps mitigate operational risks and enhances security for fund assets.

For J.P. Morgan and Morgan Stanley, selecting two custodians ensures that the fund's Bitcoin is stored in both cold and trading wallets, depending on the needs of share creation and redemption processes as explained. These custodians are responsible for safeguarding the fund's digital assets and facilitating secure transfers as reported.

What Are the Implications for Market Structure and Risk Management?

The centralized custody structure for Bitcoin ETFs has drawn attention from analysts and regulators. The custody agreement determines who can act on the fund's assets when markets are closed, potentially creating operational risks if a single custodian faces issues according to analysis.

Morgan Stanley's Bitcoin Trust will use BNY Mellon not only for Bitcoin custody but also as the fund administrator and cash custodian according to filings. This multi-tiered role may streamline operations but could also concentrate power in one institution, raising concerns about systemic risk as noted.

J.P. Morgan's decision to use the same custodians as BlackRock suggests a preference for proven infrastructure. BNY Mellon's role as a cash custodian and administrator in other Bitcoin ETFs indicates a broad trust in its capabilities according to reports.

What Comes Next for Bitcoin ETFs?

Both J.P. Morgan and Morgan Stanley are advancing their Bitcoin ETF proposals with the U.S. Securities and Exchange Commission. The approval of these funds could expand institutional access to Bitcoin and influence the broader market. The use of multiple custodians may also set a precedent for other ETF providers seeking to meet regulatory expectations.

Analysts are watching whether additional providers will adopt similar custody strategies. The concentration of custodial roles among a few firms may affect the diversity of the market and the resilience of Bitcoin ETFs in the event of operational disruptions according to analysis.
