A family office can have an excellent investment strategy and still lose control of its capital in the plumbing. Funds sit with the wrong counterparty, securities are recorded in the wrong name, a capital call arrives when cash is locked in a term deposit, or a payment is released on a single email instruction. Banking, custody and treasury management are the functions that decide where money sits, who holds title to assets and who may move them. Within Family Office Advisory, they form the operating infrastructure that turns an investment policy into controlled execution across entities and jurisdictions. Each function protects against a different failure, and none can substitute for the others. Strategy decides what capital should do. Treasury decides whether it can.
Why Banking, Custody and Treasury Management Must Work as One System
Banking provides accounts, payments, credit and currency access. Custody holds and records investment assets, separates them from the custodian’s own balance sheet and services them through settlement, income collection and corporate actions. Treasury is the internal function that forecasts liquidity, allocates cash between entities and controls who can authorise movements.
These functions are often built at different times by different people. The first bank account is opened when the holding company is formed. A custodian is appointed when the portfolio grows. Treasury is formalised only after a liquidity shortfall or a payment error. The result is a set of relationships that work individually but are not coordinated. Coordination is the control.
| Function | What It Controls | Main Risk It Addresses | Typical Provider |
|---|---|---|---|
| Banking | Cash accounts, payments, credit facilities, foreign exchange | Counterparty concentration and loss of payment capability | Commercial and private banks |
| Custody | Safekeeping, title records, settlement, asset servicing | Loss or misrecording of investment assets | Global or regional custodians, prime brokers |
| Treasury | Liquidity forecasting, cash allocation, payment authority, hedging | Liquidity gaps, unauthorised payments, unmanaged currency exposure | In-house team or outsourced treasury provider |
How Should a Family Office Structure Its Banking Relationships?
Banking relationships should be designed by purpose rather than accumulated by habit. A typical structure allocates transactional banking, investment access, lending and international payments to specific institutions, with at least two banks capable of handling critical payments so that the office is never dependent on a single counterparty.
Accounts should follow legal structure. The holding company, each special purpose vehicle, any operating entities and a foundation, where one exists, should hold their own accounts. Commingling cash across entities undermines the separation that the structure was designed to create, complicates accounting and can weaken asset protection if one entity faces a claim.
Currency is a risk variable rather than a transactional detail. Families with liabilities in several currencies should decide, as a matter of policy, which exposures are hedged, which are matched with assets in the same currency and which are deliberately left open.
In the UAE, banks are licensed and supervised by the Central Bank of the UAE, while financial institutions in the Dubai International Financial Centre and Abu Dhabi Global Market are regulated by the DFSA and the FSRA respectively. Account opening for family office entities involves detailed know-your-customer and source-of-wealth review, including identification of ultimate beneficial owners. Families should expect this process to take time and plan entity formation and banking in parallel.
What Does Good Custody Look Like?
Custody separates ownership of assets from the institution that executes transactions. Assets should be held in segregated accounts in the name of the relevant family entity, so that they remain identifiable as the client’s property if the custodian or broker fails. The custody agreement should be read for sub-custody arrangements, rights of set-off or lien, and the custodian’s liability standard.
Private market investments often sit outside the custodian. Fund interests, direct holdings and co-investments are recorded in subscription documents, share registers and partnership records. The family office must therefore maintain its own master record of all holdings, reconciled regularly to custodian statements, fund administrator reports and registry extracts. Without that reconciliation, the office cannot be certain what it owns.
Custodian selection deserves the same diligence as manager selection. Relevant factors include the custodian’s regulatory status and credit standing, its network of sub-custodians in the markets where the family invests, the quality and timeliness of its reporting, its fee structure and its ability to support the family’s entities and reporting currency. Using more than one custodian reduces concentration but increases the reconciliation workload, so the decision should be deliberate rather than incidental.
Treasury: Liquidity Planning and Cash Allocation
Treasury forecasts inflows and outflows across every entity and maps them against obligations: operating costs, capital calls, distributions to family members, debt service and tax. Liquidity should be planned in tiers, each held in instruments that match its time horizon.
Intercompany funding should be documented. Loans between family entities need written terms, and in the UAE the Corporate Tax regime under Federal Decree-Law No. 47 of 2022 applies the arm’s length principle to transactions between related parties. Informal transfers between entities are therefore both a control weakness and a potential tax exposure.
A Worked Example: Tiering AED 400 Million of Liquidity
Consider an illustrative single family office with AED 400 million of liquid assets, annual operating and family costs of AED 24 million and AED 60 million of unfunded commitments to private equity funds expected to be called over three years.
| Tier | Purpose | Illustrative Amount | Instruments |
|---|---|---|---|
| Operating reserve | Twelve months of costs and distributions | AED 24 million | Current and call accounts across two banks |
| Commitment reserve | Capital calls expected in the next eighteen months | AED 30 million | Short-dated deposits and money market funds |
| Contingency buffer | Unexpected calls, opportunities, market stress | AED 26 million | Liquid securities plus an undrawn credit line |
| Strategic capital | Long-term investment portfolio | AED 320 million | Diversified portfolio held with custodians |
Before tiering, the office held almost all of its liquidity in a single long-term portfolio and met capital calls by selling securities when notices arrived. In a falling market, that meant selling at a loss to fund commitments. With the tiers in place, the first eighteen months of calls are pre-funded, operating costs are covered for a full year and a credit line provides a further bridge. The strategic portfolio is no longer a source of emergency cash. It can be managed for its intended horizon.
Original Analysis: The Five-Key Treasury Chain
Capital moves safely only when five controls operate in sequence. The Five-Key Treasury Chain treats each as a key that must turn before the next can work. A weakness at any point breaks the chain, regardless of the strength of the others.
Key 1: Hold
Cash sits with diversified, purpose-defined banks in accounts that mirror the legal structure.
Key 2: Safeguard
Investment assets are held in segregated custody or recorded in registers in the correct entity’s name.
Key 3: Forecast
Treasury maintains a rolling liquidity forecast across all entities and holds tiered reserves against known and contingent obligations.
Key 4: Authorise
Every payment passes through segregated initiation, verification and approval, with thresholds that escalate authority as amounts rise.
Key 5: Reconcile
Bank, custodian and registry records are reconciled to the office’s master record on a fixed cycle, and every break is investigated and closed.
Authorisation is the key most often weakened in practice, because it is the one that slows things down. It is also the one that prevents the most damaging losses. Payment fraud through impersonated instructions targets precisely the moment when a trusted person asks for urgency.
| Payment Size (Illustrative) | Initiation | Approval | Additional Control |
|---|---|---|---|
| Up to AED 250,000 | Treasury officer | One authorised signatory | Beneficiary pre-approved in bank system |
| AED 250,000 to AED 5 million | Treasury officer | Two signatories, one senior | Call-back on new or changed beneficiary details |
| Above AED 5 million | Head of treasury | Two signatories plus CIO or CEO | Investment committee or board resolution on file |
| Any payment to a family member | Treasury officer | Per distribution policy | Matched to approved distribution schedule |
Credit, Risk and Cross-Border Considerations
Credit facilities, whether revolving lines, securities-backed lending or asset-level financing, can bridge commitments and avoid forced sales. They should be used within limits set by the investment committee, with covenants, margin call mechanics and collateral eligibility understood before drawing.
Cross-border cash movement requires attention to withholding taxes, exchange controls in the source country and documentation that evidences the commercial purpose of transfers. Single family offices established under the DIFC or ADGM regimes should ensure that their treasury activity stays within the scope of their registration and does not drift into regulated activity for third parties.
Who Governs Treasury, and How Is It Reported?
Treasury should operate under a written policy approved by the family office board or investment committee. The policy sets the liquidity tiers, approved banks and custodians, counterparty limits, hedging rules, borrowing limits and the payment authorisation matrix. Management executes within the policy. Any exception, such as a temporary breach of a counterparty limit during a large transaction, should be approved and recorded rather than tolerated.
Bank mandates and signatory lists must match the policy. This sounds obvious, but mandates are often set up at account opening and never revisited. A director who has left the family office, or a family member who no longer has an executive role, may still hold signing authority at one bank. A semi-annual review of every mandate against the current authorisation matrix closes that gap.
Reporting should give decision makers a single view. A monthly treasury report would typically show cash and liquid assets by entity, bank and currency; the position of each liquidity tier against its target; upcoming capital calls and distributions; credit facilities drawn and available; counterparty exposure against limits; and open reconciliation breaks. Treasury management systems that connect to bank and custodian feeds reduce manual work and errors, but the system does not replace the policy. It only shows whether the policy is being followed.
Finally, the treasury function should be tested. An annual review by internal audit or an external adviser should sample payments against the matrix, confirm reconciliations were completed and check that reserves were maintained. Controls that are never tested tend to erode quietly.
Common Failures in Family Office Banking and Treasury
- One bank holds most of the cash and payment capability, so a frozen account or operational outage halts the office.
- Entities share accounts, which blurs ownership, complicates audit and can undermine the protection the structure was meant to provide.
- Capital calls are funded by selling long-term assets because no commitment reserve was maintained.
- A single person can both create a beneficiary and approve a payment to it, leaving the office exposed to error and fraud.
- Private market holdings are not reconciled because no custodian holds them, so the master record drifts from reality.
- Intercompany loans are undocumented, creating both governance weakness and transfer pricing exposure under the UAE Corporate Tax regime.
- Bank relationships are never reviewed, so pricing, service quality and credit terms are accepted rather than negotiated.
None of these failures is caused by complexity. Each is caused by a missing control that would have been inexpensive to put in place.
Conclusion
Banking, custody and treasury management determine whether a family office’s capital is where it should be, recorded in the right name and available when it is needed. Banking should be structured by purpose and spread across counterparties, with accounts that mirror the legal structure. Custody should keep assets segregated and reconciled, including private holdings that no custodian sees. Treasury should forecast liquidity in tiers, document intercompany funding on arm’s length terms and enforce payment authority that escalates with amount. The Five-Key Treasury Chain brings these controls together: hold, safeguard, forecast, authorise and reconcile. Each key protects against a different failure, and the chain is only as strong as its weakest link. Families that build it early rarely need to explain a loss. Families that build it after a loss rarely forget why. Control is designed in advance.
