Operations
Rarely by design. Within a few years a firm that intended to run one is running three, and nobody ever decided to.
Rarely by design. A breakaway brings relationships from a previous firm. An acquisition arrives with a different custodian. A large client refuses to move. Within a few years a firm that intended to run one is running three, and nobody ever decided to.
| Area | What multi-custodial adds |
|---|---|
| Trading | Separate blotters, different cut-offs, allocation across venues, and block trades that cannot be blocked |
| Billing | Different fee-deduction mechanics and file formats, reconciled separately |
| Reporting | Data arriving in different shapes on different schedules |
| Reconciliation | The real cost — it does not add, it multiplies |
| Service | Multiple relationships, portals, and escalation paths |
The reconciliation line is where firms underestimate. Two custodians is not twice the work; it is twice the work plus the effort of making two sets of records agree with one set of books.
When the reason has expired. Most multi-custodial arrangements outlive the situation that created them — the client who insisted has moved on, the acquired book has turned over, the capability gap has closed. Nobody revisits it, because the cost is diffuse and the migration is visible.
A reasonable discipline: review it annually and require a current reason, not a historical one.
The operational burden of multi-custody is almost entirely a function of whether your systems treat the custodian as an attribute of an account or as a separate world. If positions from four custodians land in one set of records, reconciled centrally, then multi-custodial is a fact rather than a project. If each custodian implies its own workflow, the cost is real and compounds.
We run four live — Charles Schwab, Interactive Brokers, Axos and Apex — and never take custody ourselves. That is a deliberate structure: clients stay where they are, and no migration is required to change what runs on top.
