Private banking: onboarding, published thresholds, scope of services and Lombard lending risk

Private banking is a bank's business line for high-net-worth clients, bringing custody, investment advice, discretionary mandates, credit and wealth planning together under one client relationship. In a one-stop solution, the private bank usually acts as the hub for custody and financing: the family-office account, premium financing and Lombard loans all sit here. It does not replace lawyers, tax advisers or trust companies, and it does not guarantee investment outcomes.

Section overview

Definition and distinctions: retail and priority banking (such as services for clients with several hundred thousand Singapore dollars) centre on deposits and standardised products. Private banking serves clients with larger asset bases, offering multi-currency custody, open-architecture product platforms, discretionary mandates and credit secured on assets, and coordinates external services such as trusts and insurance.

Regulation: private banks operating in Singapore are MAS-licensed banks or financial institutions, and private-bank relationship managers giving investment advice are subject to the rules on financial advisers. In a media release on 5 April 2011, MAS welcomed the industry's launch of the Private Banking Code of Conduct (effective 1 September 2011). Under the Code, private-banking practitioners must pass a common competency assessment before giving financial advice — the Client Advisor Competency Standards (CACS) administered by the Institute of Banking and Finance (IBF) (MAS, 5 April 2011). Later revisions of the Code follow the current version published by The Association of Banks in Singapore (ABS).

Relationship with Accredited Investor (AI) status: many private-bank products are offered only to AIs. Becoming an AI gives access to more products, but some retail investor protections no longer apply, which is why investors must actively opt in.

Market context: in a speech on 29 September 2025, the Deputy Chairman of MAS noted that private banking client assets in Singapore grew by 19% in 2024.

Solution structures

Fee structures: common charges include custody fees, advisory or discretionary fees based on assets, transaction commissions, product-embedded charges and loan interest. This site has not found a publicly verifiable range of private-bank fees and therefore quotes no figures; when comparing, ask the bank to set out in writing every layer of fees and its conflict-of-interest disclosures.

Key rules and figures

Source of wealth and source of funds: source of wealth answers "how were all of these assets built up?", while source of funds answers "where did this particular deposit come from?". Acceptable evidence usually includes salary records and tax assessments, bank statements, audited financial statements of controlled companies, share-sale documents and trust deeds. Private-bank accounts also require CRS and FATCA self-certifications, and account information is reported under those rules; see Residency and tax.

Risks and common misconceptions

1. Forced sale under a Lombard loan → Trigger: the market value of the pledged portfolio falls, or the bank cuts its lending values → Mitigation: understand the top-up thresholds and deadlines. Taking the terms of HSBC Bank (Singapore) as an example, the net margin ratio (NMR) must be kept at no less than 100%; where the NMR is between 80% and 100%, the top-up period is 60 calendar days, and between 60% and 80%, five business days; at 60% or below, the bank may sell the collateral, whether or not a margin call has been issued (effective 30 April 2025; an example of the mechanism only — terms vary between banks).
2. Concentration and currency → Trigger: the portfolio is concentrated in a single stock or region, or in a currency different from the liabilities → Mitigation: set concentration limits, and match the loan currency to the currency of income or assets as far as possible.
3. Treating the private bank as a capital-guaranteed channel → Trigger: assuming that structured products or bonds recommended by the private bank are capital-protected → Mitigation: confirm for each item whether it is insured, who the issuer is and how much could be lost in the worst case.
4. Reduced protection as an AI → Trigger: accessing complex products after opting in to AI status → Mitigation: record investment objectives and risk tolerance in writing, and ask for a suitability explanation.
5. Stacked fees and conflicts of interest → Trigger: the same assets bear advisory fees, product-embedded charges and transaction fees at once, or the adviser's remuneration is linked to products → Mitigation: ask for all fees and sources of remuneration in writing.
6. Gaps in the source-of-funds evidence trail → Trigger: assets have passed through several transfers, nominee holdings or cross-border remittances → Mitigation: assemble a complete evidence trail before onboarding, and do not use nominee arrangements.

Next steps

1. Work out investable assets and AI eligibility first, and confirm whether you really need a private bank or whether priority banking would be enough.
2. Prepare a source-of-wealth narrative and evidence trail, together with identity, address, tax-residence and TIN documents; see the document and due-diligence checklist.
3. Decide the account holder — individual, company, family-office entity or trust — and have a lawyer confirm the documents are consistent.
4. If you need a Lombard loan or premium financing, ask the bank first to explain in writing the top-up thresholds, deadlines and disposal rules, and run a stress test.
5. Ask the bank to set out in writing every layer of fees and its conflict-of-interest disclosures, then compare them against the allocation framework in the Wealth management section.
