SD-12.5 — Custody & Safekeeping Oversight

Business Domain: BD-12 Investment Operations & Servicing (Back office) · Applies: BOTH

Purpose

Oversees the safekeeping of the institution’s assets at custodians, depositories and other asset-holding agents — confirming that what the custodian holds matches what the firm believes it owns, controlling the safekeeping accounts, and managing the operational interaction with the custodian and, where one is appointed, the depositary. The firm rarely holds its own assets; they sit with a custodian. SD-12.5 is the capability that oversees that arrangement at the asset level. It exists because custody is an asset-safety control, not a clerical one — the firm must independently know its assets are there, correctly recorded and unencumbered. It is not trade settlement — that is SD-12.4, which processes the event that moves assets in and out — and it is not the commercial management of the custodian as a vendor — that is SD-17.8. SD-12.5 watches the assets; SD-17.8 manages the contract.

Service Operations

• Custodian-holdings oversight — confirm that the custodian’s record of holdings matches the firm’s book, asset by asset and account by account, as the front line of asset-safety assurance.
• Safekeeping-account control — maintain and control the custody and safekeeping account structure: account opening and closing, the mapping of portfolios to accounts, and the access and authority over them.
• Depositary interaction — where a depositary is appointed (as fund regulation requires for certain vehicles), manage the operational interface with it — the asset-verification, cash-monitoring and oversight functions a depositary performs.
• Asset-segregation verification — verify that the firm’s assets are segregated from the custodian’s own and from other clients’, and held in the correct (often client-designated) account structure.
• Sub-custodian and network oversight — oversee the sub-custodian network the global custodian uses in local markets, where the firm holds assets across jurisdictions.
• Custody-event support — support the asset-level handling of custody-network events — account transitions, market openings, custodian changes — and the safekeeping side of a custodian transition.
• Holdings-statement validation — validate the periodic holdings and activity statements the custodian issues, the source records reconciliation and reporting draw on.

Inputs and outputs

• Inputs: custodian holdings and activity statements; the firm’s book of record from SD-12.1 / SD-12.2; settled-trade records from SD-12.4; the account structure.
• Outputs: validated custodian holdings records and asset-safety assurance — consumed by SD-12.10 Reconciliation (the custodian side of the position reconciliation), SD-14.1 Enterprise & Operational Risk Management, SD-14.8 Internal Audit, SD-17.8 Vendor, Outsourcing & Service-Provider Oversight (asset-level evidence into the commercial review); account-structure detail — consumed by SD-12.4 Trade Settlement and SD-11.7 Bank Account & Mandate Administration.

Entities

• Consumes: E-04 Holding / Position (any book — custody oversight checks both the IBOR and ABOR firm-side records against the custodian’s holdings statement), E-01 Legal Entity (custodian, sub-custodian and depositary roles), E-03 Portfolio / Mandate; the SD-12.1 firm’s book of record; the SD-12.2 firm’s book of record; the SD-12.4 settled-trade records; FO-08 Service-Provider Appointment (reads the role = custodian and role = depositary appointment rows for each fund to identify which E-01 entity fulfils each role — the custodian appointment governs the holdings-verification interaction; the depositary appointment governs the independent oversight interaction; the two are distinct rows and distinct operational modes, reflecting the depositary’s NAV/cashflow/dealing-oversight duty under UCITS and AIFMD versus the custodian’s safekeeping duty); FO-11 ETF Creation Basket (reads the daily Portfolio Composition File to verify that basket securities delivered or received by an authorised participant in settlement of ETF creation/redemption orders match the authoritative daily composition; the safekeeping function confirms in-kind deliveries against the published PCF).
• Owns: E-25 Account for the account_type = safekeeping partition — the custody and safekeeping account structure linking portfolios to custodians and depositories, aligned to FIBO’s Account concept. E-25 is key-partitioned and co-equal: SD-12.5 owns the safekeeping side, SD-11.7 Bank Account & Mandate Administration owns the account_type = cash side, and SD-15.4 Distribution Strategy & Channel Management owns the account_type = register side (fund-register / nominee accounts); it is one shared account master. The custodian, sub-custodian and depositary remain roles of E-01 Legal Entity (owned by SD-13.2); the holding is owned by the book-of-record domains.

Standards

• ISO 20022 / ISO 15022 — the messaging standards custodian holdings and activity statements are delivered on (the ISO 15022 MT535 holdings statement, MT536 / MT537 statements of transactions and pending transactions, and their ISO 20022 successors).
• Depositary regulation — the EU AIFMD and UCITS depositary regimes (and equivalent regimes elsewhere) define the depositary’s asset-verification and oversight duties this Service Domain interfaces with.
• Custody operates within the same asset-segregation and client-asset-protection rules — local client-asset regimes — that govern how a custodian must hold client property.

Open extensions

• The Service-Operation-level input/output contracts.
• The account-hierarchy sub-model on E-25 — sub-accounts, omnibus structures and the mapping of a portfolio across multiple accounts.
• The sub-custodian network sub-model — depth of the custodian → sub-custodian → place-of-safekeeping chain.
