State Street's exploration of blockchain for custody and fund administration raises the question most institutions eventually face: when does this technology actually fit, and when does it not?
News that State Street Bank is exploring blockchain for payment settlement in custody and fund administration has prompted a familiar question from clients and colleagues: when should a firm seriously investigate blockchain, and when is it simply not the right tool for the problem at hand?
The Oxford Blockchain Strategy Framework offers a useful diagnostic, and I have applied it here in the context I know best: custody and portfolio administration for alternative investments. Having managed exactly these processes at HSBC Alternative Investments for 18 years, including the outsourcing of a $2.5bn transfer agency function, the practical realities of this use case are ones I understand in detail.
The first question the framework asks is whether the process is predictable and repeatable. In custody and fund administration, the answer is almost always yes. Transaction settlements, dividend and interest collections, foreign exchange transactions, securities transfers, reconciliation cycles, and fee charges are all defined in advance through service level agreements. Predictable, repeatable processes are precisely where smart contracts on a blockchain can execute efficiently and reliably, without the manual intervention that currently creates cost and risk.
The second question is whether the transactions are ongoing or long-running rather than one-off events. Again, portfolio administration scores strongly here. Daily, weekly, monthly, and quarterly processes are the norm. Reporting, approvals, and reconciliations run continuously across the lifetime of each fund. Blockchain's ability to manage long-running process chains without degradation of data integrity is directly relevant.
Multiple stakeholders is the third criterion, and custody and fund administration involves many: custodians, sub-custodians, transfer agencies, central securities depositories, fund managers, investment advisors, regulators, and end clients. When this many parties need access to the same data and need to trust it, a unified blockchain platform that gives all participants a single, verified view of the truth is significantly more efficient than the current model, where each party maintains its own ledger and spends considerable resource reconciling against everyone else's.
That reconciliation burden is itself the fourth criterion. Today, custodians act as arbiters of the official record, and every other party reconciles against them. The errors, breaks, and manual intervention this generates are substantial. At HSBC I engineered a data reconciliation model that reduced reconciliation breaks from 17,000 to zero for a portfolio of over 400 Swiss accounts, but that required significant bespoke technology investment. Blockchain's immutable shared ledger addresses the root cause rather than the symptom.
Value transfer is inherent to the use case. Subscriptions, redemptions, and corporate action events move securities and cash constantly. And the requirement for immutable records is driven by regulation across GDPR, MiFID II, PRIIPs, and FCA standards, all of which demand transaction data held from a portfolio's inception.
Across all six criteria, custody and fund administration passes the test. That does not mean implementation is straightforward; legacy technology integration, smart contract complexity for hedge fund redemption logic, and governance redesign across the value chain are real challenges. But the fit between the technology and the use case is genuine. For institutions still asking whether blockchain is relevant to their operations, that question has a clear answer in this context.
