Banking and custody for a Singapore family office

What do banking and custody mean for a Singapore family office?

Banking covers deposits, payments, foreign exchange and credit: the daily movement of money. Custody covers the safekeeping of securities and other assets, with records of what the family owns. A Singapore family office usually needs both, and each has its own provider, its own forms and its own fees. Seeing the two functions apart makes the later choices easier.

The family stays the owner of assets held in custody, while the custodian keeps the records and executes instructions from authorised people. That division gives the office a clear answer to a simple question: who holds what, in whose name, and who can give instructions? Everything else on this page builds on that answer.

Which accounts does a family office in Singapore usually need?

Most offices work with 4 account roles. An operating account pays salaries, rent and advisers. An investment account holds the portfolio under the family’s policy. A custody account keeps assets in safekeeping. Signatory rules, the fourth role, set who approves each movement. The table shows the 4 roles side by side so you can map them to your structure.

Match each role to the right owner. The office company may hold the operating account, while a trust or a fund vehicle may hold the investments. Which entity owns which account depends on the legal structure you choose. List the entity, the purpose and the currency of each account before you contact any bank.

How does a family choose a bank for its family office?

Start from your needs, not from a brand. Write down the currencies you hold, the entities that need accounts, the markets you invest in and the reporting you expect. Then shortlist banks and custodians that serve family offices and compare them on these points. Service quality, access to the relationship team and clear fee schedules matter as much as the headline offer.

Run the comparison in 5 steps: define needs, shortlist providers, share documents, open accounts, and review after the first quarter. The review closes the loop, because real statements and real response times show whether the provider fits. Many families keep a second provider in reserve, so that one relationship never carries all the accounts.

Why do banks ask a Singapore family office about its owners and wealth?

Banks work under anti-money-laundering rules. The Monetary Authority of Singapore (MAS) says financial institutions must identify and know their customers, including beneficial owners, perform regular account reviews, and monitor and report suspicious transactions. A family office therefore expects questions about the people behind each entity and about where the wealth comes from. Those questions apply to every client, whatever its size.

Prepare clear answers before the bank asks. Build an ownership chart, a short account of how the wealth was created, and records that support each point. The detailed page on AML and KYC checks lists the typical requests and shows how to organise your file, so the review becomes a routine exchange.

Where does account opening fit in the family office setup?

Accounts follow the entity. A bank asks for the registered company or vehicle, its owners, its directors and its purpose, so the legal structure and the registration come first in the sequence. Timing varies by bank and by file, which is why a family starts the conversation early in its plan.

The detailed page on opening bank accounts covers the documents, the order of the application and the timing you can plan around. Read it once your structure is clear, and keep the documents in one shared folder so each provider receives the same consistent set.

How does a family keep control over banking and custody?

Control comes from rules written before the first transfer. Define who may sign, up to which amount, and which movements need 2 approvals. Give each person a role that matches their responsibility, and review the list whenever someone joins or leaves. Clear signatory rules protect the family and the staff who execute the instructions.

Add one consolidated view. Statements from several banks and custodians arrive in different formats, and the office turns them into a single balance sheet each month. That routine shows concentration, currency exposure and idle cash, and it gives the family one document to discuss at each meeting.

What should a family office record about its banking and custody setup?

Keep a living register: the list of accounts, the owner of each, the signatory matrix, the bank contacts, the fee schedules and the date of the last review. Store it where the family and the office team can reach it. A register turns scattered knowledge into a shared tool.

The register also protects continuity. When a team member leaves or a generation hands over, the next person reads one document and understands the setup. Families that plan succession find that a clear banking record shortens the handover and keeps relationships with providers steady.

How can a family decide on its banking and custody setup?

Treat the setup as a decision with several dimensions: cost, access, control and fit with the family’s plan. The EQOS Asia private page presents a scored way to weigh a family decision (EQOS Asia private page, 2026). Use that lens to rank your options, then note the dimension that scores lowest and fix it first.

A 30-minute pre-diagnostic with EQOS Asia shows which format fits your question, and a licensed adviser confirms the details for your structure. This page is general information, not legal, tax or investment advice, as of October 2026. Return to the full setup guide whenever you need the wider sequence.
