Private banking in Singapore: accredited investors, onboarding, credit

A Singapore private bank holds a wealthy client's assets in custody, gives investment advice or runs a discretionary mandate, lends against those assets and coordinates with trust and insurance arrangements. Most of its products are open only to accredited investors who have opted in, which reduces some regulatory safeguards, and every client should expect a source-of-wealth review at onboarding.

Scope and scale

Private banking is a relationship-based banking service for wealthy clients that combines custody of assets, investment advice or discretionary management, lending against assets and coordination with trust and insurance arrangements. In Singapore it is delivered by banks and merchant banks regulated by the Monetary Authority of Singapore (MAS). It differs from priority or premier banking mainly in scope: products restricted to accredited investors, credit secured on portfolios, and the ability to open accounts for companies, trusts and family offices.

The segment is growing. MAS's Deputy Chairman said private banking client assets grew by 19% in 2024 (speech, 2025-09-29). Growth has come with closer scrutiny: since the 2023 money-laundering case, banks have tightened onboarding and expect more documentation about how wealth was built.

A private bank is a counterparty and a distributor as well as an adviser. It earns fees, spreads and, in some cases, payments from product providers, so the client should understand how each service is paid for. Minimum account sizes are set commercially by each bank and are not covered on this site.

Who regulates it

Accredited investor thresholds for individuals under SFA section 4A:

1. net personal assets exceeding S$2 million, with the net equity of the primary residence (in Singapore or overseas) counted at no more than S$1 million; or
2. net financial assets, net of related liabilities, exceeding S$1 million; or
3. income in the preceding 12 months of not less than S$300,000.

Corporations qualify with net assets exceeding S$10 million. MAS noted the criteria were last updated in 2018 (written reply, 2025-02-05). "Related liabilities" include margin accounts and credit lines used to finance a portfolio, so borrowing reduces the figure that counts.

What it solves and what it does not

Private banking solves access and coordination problems. It gives one relationship for multi-currency custody, consolidated statements, credit and introductions to trust and insurance specialists. Accredited investor status opens restricted schemes and other products that are not offered to retail investors; a restricted scheme can otherwise be offered only to relevant persons or at a minimum of S$200,000 per transaction (MAS, updated 2026-10-05).

It does not guarantee better outcomes. Becoming an AI means giving up some protections: MAS says AI status "will not avail them to the same level of regulatory safeguards as retail investors", although firms must still consider a client's profile, risk tolerance and financial knowledge (2025-02-05). A private bank also does not settle succession, tax residence or ownership questions; it acts on the structure it is given. An account in the name of a company or trust needs that structure to exist first (see the process).

Typical structures

The booking centre (where the account is legally held) can differ from where the relationship manager sits. It determines which law and regulator apply, which deposit insurance scheme (if any) covers cash, and which jurisdiction reports the account under the CRS. When an account is held by a company or trust, the CRS and FATCA classification of that entity, and the identity of its controlling persons, decide who is reported; the bank will ask for entity self-certifications as well as personal ones. Families that hold accounts in several booking centres should keep one table listing each account, its holder, its booking centre and its reporting jurisdiction.

Key risks

• Credit and margin calls. A Lombard loan is secured on a portfolio at a loan-to-value ratio set by the bank. If prices fall or the bank lowers the ratio, the client must add collateral or sell. Approval, loan-to-value, interest rate and margin terms are decided by the lender and can change during the loan. See financing and leverage.
• Concentration. Large positions in one stock, one bond issuer or one structured product can dominate results.
• Complex products. Structured notes, private funds and derivatives carry liquidity and valuation risks that may be hard to assess.
• Fees and conflicts. Advisory fees, transaction charges, product spreads and retrocessions should be disclosed in writing.
• Onboarding delay or exit. Inconsistent facts, missing evidence or nominee arrangements can stall or end a relationship. Industry guidance expects firms in this segment to establish the source of wealth of all customers and their beneficial owners (ACIP, 2025-05).

Professionals you will need

• Relationship manager and investment counsellor – onboarding, mandates, product selection.
• Credit specialist – facility terms and security.
• Accountant or lead adviser – prepares the source-of-wealth file (see source of wealth).
• Lawyer – reviews credit, security and account-mandate documents; sets up holding entities.
• Trustee – where a trust holds the account.
• Tax adviser – reporting of the account in each jurisdiction where the holder is tax resident.

In family-office cases the fund administrator and the SFO's investment professionals also deal with the bank directly, so authority to give instructions should be set out in the account mandate rather than assumed. The bank decides whether to accept a client and on what terms. The family's own advisers should check that the bank's understanding of the facts matches the file used by the insurer and the trustee, as described in the professional-collaboration model.

Five due-diligence questions

1. Which protections do I give up by opting in as an accredited investor, and can I opt out later?
2. Is the mandate advisory or discretionary, and what are all the fees?
3. If I borrow, what loan-to-value applies, how are margin calls triggered, and how long do I have to respond?
4. Which booking centre holds the account, and under which law?
5. Who handles complaints, and does FIDReC apply to this booking centre and product?

Each answer should be recorded with the date and the name of the person at the bank who gave it, because terms such as loan-to-value ratios can change. The private-banking section of the due-diligence checklists adds questions on concentration, booking centre and conflicts.

Where to go deeper

Chinese readers can find the same section on hnwsolution.sg, and account opening after arrival is covered on hnwi.sg. On this site, wealth management explains how assets held at a private bank can be organised by purpose, and compare shows how private banking differs from the other solution areas. Bank minimums and pricing change and are set by each institution, so they should be confirmed directly. The relationship with a private bank is usually the most visible part of an HNW structure, but it works best when the trust, company and insurance decisions behind it are already documented, because the bank will onboard the structure as it stands and ask for changes to be evidenced later.
