Coinbase’s Dominance in Bitcoin ETF Custodianship Raises Concerns

Coinbase, a leading digital asset exchange, plays a central role in the world of Bitcoin ETFs, holding custody for eight out of eleven sanctioned ones. This prominent position in the ETF market is not limited to custodianship; it also extends to a broad range of services including trading and lending, especially highlighted in their collaboration with major industry player BlackRock.

Concerns, however, are surfacing from blockchain experts and ETF consultants regarding Coinbase’s extensive responsibilities. This concentration of duties in a single platform is seen as a potential risk, a viewpoint echoed by the SEC. The SEC has raised issues about the risk associated with Coinbase’s dominance in ETF custody, and has been involved in legal actions against the company, challenging its operation as an unregistered exchange and broker-dealer. Coinbase, on their part, strongly refutes these allegations.

David Schwed, COO at blockchain security firm Halborn, highlighted in a Bloomberg interview the potential issues with such concentration. Traditionally, financial market infrastructures are designed with divided roles to prevent such risk accumulations. Schwed suggests that entrusting Coinbase with multiple aspects of a trade’s lifecycle might be challenging.

Another point of concern is the dependency of ETF issuers on Coinbase’s comprehensive services, as noted by Dave Abner of Dabner Capital Partners, an ETF consultancy. He expressed surprise at the lack of mandates for issuers to diversify their custodians as a risk precaution.

In light of these apprehensions, Coinbase’s CFO Alesia Haas has assured that the company is dedicated to minimizing conflicts of interest. She clarified that the company’s custody services are not part of the ongoing SEC dispute.

Coinbase’s significant role also encompasses an exclusive partnership with BlackRock, acting as the sole trading agent for their Bitcoin ETF through Coinbase Prime. Additionally, Coinbase’s lending service, though smaller, plays a crucial part in the Bitcoin ETF structure, enabling entities like BlackRock to borrow Bitcoin or cash for short-term trading purposes.
