Private Banks in Singapore by AUM: The 2026 Evidence Ledger

Updated 5 October 2026. Financial observations are dated individually below; most relate to 30 June 2026.

Which private banks in Singapore have the most assets under management? The first question is where those assets sit. UBS disclosed USD 790 billion in Asia-Pacific invested assets at June 2026. LGT published USD 178 billion for its Asia-Pacific business. DBS reported SGD 516 billion across its wider wealth franchise. None of those figures is a Singapore-only private-bank balance.

That distinction changes the shortlist. A bank can have an enormous global investment platform and a comparatively small local team. Another can manage less worldwide yet offer precisely the booking centre, lending terms and relationship coverage a family needs.

This guide brings together primary-source disclosures for 16 banking and wealth brands with a Singapore presence. It separates regional books, global private-banking businesses and broader wealth franchises, then examines what scale can tell a prospective client. What it cannot tell you matters just as much.

The Singapore Ranking That Public Accounts Cannot Give You

A useful Singapore-only ranking would need every institution to disclose private-client assets booked through its Singapore operation, on the same date, under a common definition. The public material reviewed for this article does not supply that complete dataset.

Instead, disclosures describe different businesses. UBS provides an Asia-Pacific regional view. Pictet publishes a global Wealth Management number as well as a much larger group total that includes custody. Singapore-headquartered banking groups disclose wealth franchises that span several client tiers and markets.

Those figures answer different questions. Regional AUM shows commercial weight across a region. Global private-banking assets indicate the reach of a platform. A broader wealth-franchise total may include affluent clients well below the institution’s private-bank threshold.

Location adds another complication. A client living in Singapore may have assets booked elsewhere. A non-resident may use a Singapore account while their adviser covers several jurisdictions. Client residence, relationship-manager location and legal booking entity are three separate fields, not interchangeable descriptions of the same assets.

MAS describes Singapore’s wealth-management ecosystem as including more than 40 global and regional private banks. This guide is a selected evidence ledger, not an exhaustive list of licensed institutions. For the broader industry’s direction, see our analysis of Singapore banking trends.

Private Banks in Singapore by AUM: The 2026 Evidence Ledger

The table records the most recent clearly attributable observation located in the cited material. A later announcement can contain an older balance-sheet date. Bank of Singapore’s row deliberately retains a disclosed lower bound from its 2025 annual review rather than turning that statement into an invented June 2026 balance.

Every amount below is in billions. The geographical scope and asset definition travel with the number. OCBC appears as parent context, and LGT appears at both regional and group level; these are overlapping observations, not additional banks to add into a market total.

18 sourced observations, covering 16 bank and wealth brands plus OCBC parent context.

Source links lead to bank disclosures or investor material. No common-currency conversion, Singapore-only estimates or combined market total has been imposed on these observations. A bank’s appearance here does not establish eligibility for a particular client.

Two Regional Disclosures Are More Useful Than a False Top Ten

UBS: USD 790 billion is an Asia-Pacific book

UBS’s second-quarter presentation identifies USD 790 billion of Global Wealth Management invested assets in Asia-Pacific at 30 June 2026. Global GWM invested assets were USD 4,942 billion. The regional figure therefore represented approximately 16.0% of that global division, calculated from the published balances. It did not represent Singapore’s share.

For a prospective client, the regional disclosure is valuable evidence of scale. It still leaves local questions unanswered: which legal entity would hold the assets, which specialists would service the account and whether a requested facility is available through that entity. The UBS Q2 2026 presentation, regional appendix is the source, rather than an estimated league-table allocation.

LGT: the regional and group figures need different labels

LGT’s Asia-Pacific page publishes USD 178 billion of regional AUM at the same June 2026 date. Its group reported CHF 412.6 billion. Both observations belong in a reference article, but they cannot be added together or compared directly without addressing currency and reporting perimeter.

These two regional disclosures are closer to the geographical question than a global total. They still do not create a comprehensive regional ranking: they use different asset definitions, and the table does not contain equivalent regional disclosures for every competitor. Our LGT scale and client-service analysis examines what its expansion means beyond the headline.

DBS, Bank of Singapore and UOB: Three Franchises, Three Boundaries

DBS’s wealth continuum makes the headline larger than the private bank

DBS reported SGD 516 billion of wealth-segment AUM at June 2026. Its preceding year-end disclosures were SGD 365 billion in 2023, SGD 426 billion in 2024 and SGD 488 billion in 2025. The series documents a growing wealth franchise, rather than four observations of Singapore Private Bank-only assets.

From December 2023 to June 2026, the published balance increased by SGD 151 billion, or 41.4%. That is a change in reported assets, not a portfolio return. It can reflect client flows, markets, currencies and changes in the business. The distinction becomes especially important when a large wealth platform uses several service tiers.

Bank of Singapore must not inherit OCBC’s entire wealth balance

OCBC disclosed SGD 350 billion of banking wealth-management AUM at June 2026 across its wealth segments. That does not mean Bank of Singapore managed SGD 350 billion. The subsidiary’s 2025 annual review states that it surpassed its USD 145 billion target and grew AUM by more than 20% that year.

One is a parent-franchise total; the other is a private-bank statement in another currency and at an earlier date. Treating the parent figure as the subsidiary’s AUM would overstate the evidence. Adding both as separate pools would also double-count an overlapping business. For a client, the meaningful distinction is the service proposition and contracting entity, not how large a combined headline can be made.

UOB reports a high-net-worth franchise, not a local booking-centre total

UOB’s H1 2026 release reports SGD 204 billion of high-net-worth AUM, up 7% year on year. Its wealth-management income increased 16%. These measures describe a growing group franchise; they do not isolate Singapore Private Bank’s assets.

The operational question for an entrepreneur is whether the bank can connect personal investments, business liquidity and the required regional coverage without compromising transparency on charges. That is something to test in a mandate discussion. A group AUM statistic cannot settle it.

The Swiss and Liechtenstein Names: Use the Wealth Business, Not the Biggest Number

Julius Baer: distinguish AUM from total client assets

Julius Baer’s June 2026 financial information records CHF 546.7 billion of AUM. Its half-year release rounds this to CHF 547 billion and separately reports total client assets of approximately CHF 649 billion, including custody assets. Those totals measure different responsibilities.

The same release reports CHF 5.7 billion of net new money. That is a more direct indicator of new business than the entire rise in AUM, although definitions and annualisation still matter. A growing balance does not establish that a local relationship team has spare capacity or that a particular source-of-wealth profile is acceptable.

Pictet: CHF 301 billion is the more relevant wealth figure

Pictet’s Singapore Wealth Management page publishes CHF 301 billion of global Wealth Management AUM at June 2026. Its group half-year announcement reports CHF 810 billion of assets under management or custody.

The larger number describes the wider group, including businesses serving institutional clients and custody relationships. It should not replace the wealth-management figure in a client-facing comparison. Even the narrower CHF 301 billion remains global, not a measurement of the Singapore branch.

Lombard Odier: client assets and AUM tell different stories

Lombard Odier’s H1 2026 announcement reports CHF 239 billion of group AUM and CHF 367 billion of total client assets. Group AUM includes its investment-management business; it is not all Singapore private wealth.

For families comparing institutions, this is a reason to request the relevant mandate and team structure. The group balance establishes scale. It does not reveal how much investment discretion the client is delegating, how custody is charged or how the relationship will be covered. Our Lombard Odier operating-model analysis explores those questions in more detail.

EFG: the reporting date matters when an acquisition closes

EFG reported CHF 196.3 billion of revenue-generating AUM at June 2026. In its 22 July announcement, it also stated that the Quilvest acquisition had closed the previous day, taking AUM above CHF 200 billion.

Both statements can be correct. One is a June reporting balance; the other includes a subsequent transaction. The ledger retains the June figure for date consistency and records the acquisition separately. EFG’s Singapore branch and related businesses should be considered through their own service terms, not inferred from group growth.

UBP: acquisitions can change the apparent growth story

UBP’s published group AUM stood at CHF 193.5 billion in June 2026, against CHF 184.5 billion at December 2025. Its half-year release links the increase mainly to favourable markets and the performance of managed solutions and funds.

Its preceding annual figures also reflected the acquisition of Societe Generale’s private-banking activities in Switzerland and the UK. This is why a multi-year growth chart should not automatically be read as organic client recruitment. Integration quality, service continuity and the handling of inherited portfolios deserve separate questions.

Four Growth Rates That Are Not Four Investment Returns

Keeping the reporting currency and two dates fixed allows a cleaner calculation: how much did the disclosed AUM balance change? The chart below compares December 2025 with June 2026 for four groups reporting in CHF. It avoids a currency-conversion exercise, but it does not eliminate differences in business mix.

LGT added CHF 26.5 billion of reported AUM between those dates. Net new assets were CHF 12.3 billion. Subtracting the disclosed flows leaves CHF 14.2 billion of other balance movements. That remainder is not a clean investment-performance figure: markets, currency translation and other effects require the bank’s reconciliation.

A client can use this distinction to ask better questions. Did the bank grow because existing portfolios rose? Did it attract new money? Did it acquire a book? Does the reported figure include institutional asset management? Those are different developments with different implications for staffing and service.

Calculation: (June AUM / December AUM – 1) x 100; rounded to one decimal place. Sources: the banks’ half-year disclosures linked in the ledger. December balances: Julius Baer CHF 521.0bn, LGT CHF 386.1bn, Lombard Odier CHF 223.0bn and UBP CHF 184.5bn. Baseline checks also use LGT’s 2025 results and Lombard Odier’s 2025 results.

The Global Platforms: A Large Number Needs a Precise Name

J.P. Morgan: private-banking client assets are broader than AUM

J.P. Morgan’s Q2 2026 financial supplement identifies USD 3,824 billion of Private Banking client assets. Its entire Asset & Wealth Management business reports USD 5,140 billion of AUM and USD 7,663 billion of client assets.

The private-banking line is the more relevant comparator for this guide, but it remains a global client-assets measure. It must not become USD 3,824 billion of Singapore AUM. Its Singapore private-bank presence establishes a service location, not a local allocation of that global balance.

HSBC: private-bank balances are not all wealth balances

HSBC’s interim report records USD 554 billion of Private Bank client balances, comprising invested assets and customer deposits. Its wider wealth balances are a separate USD 1,577 billion measure.

Using the wider total as private-bank AUM would change both the customer population and the definition. For a client who needs substantial cash, the inclusion of deposits may be operationally relevant. For an investment-mandate comparison, it is a reason to ask for a narrower explanation.

BNP Paribas: isolate Wealth Management from asset gathering

BNP Paribas reports EUR 533 billion of Wealth Management AUM at June 2026 in its September investor presentation. Its Investment & Protection Services businesses together account for EUR 2,590 billion.

The second number includes asset management and insurance. It belongs in an analysis of the wider financial group, not in a private-bank ranking. The EUR 533 billion observation is narrower, but it still covers the global Wealth Management business rather than Singapore alone.

Goldman Sachs: assets under supervision are a separate measure

Goldman’s Q2 supplement reports USD 1,041 billion of long-term assets under supervision in its wealth-management client channel. Total Asset & Wealth Management AUS was USD 4,041 billion, including institutional and third-party-distributed assets as well as liquidity products.

The wealth-channel line gives a more focused view, yet excludes liquidity products within that measure. Neither number represents Singapore PWM AUM. Its Singapore business page confirms a local private-wealth offering; availability and the actual account entity still require confirmation.

Citi: a definition change can move the apparent baseline

Citi’s Q2 2026 supplement reports preliminary client investment assets of USD 727 billion for its wider Wealth segment. The measure includes AUM, trust and custody assets. From Q1 2026 it also includes approximately USD 10 billion associated with client insurance policies that had not previously been reported.

That footnote matters when comparing growth across years. A definition change is not a new investment gain. Nor is the wider Wealth segment identical to Citi Private Bank’s Singapore operation. Keep both the scope and the preliminary status attached to the number.

Morgan Stanley: do not assign the reported wealth segment to MSBAL

Morgan Stanley’s Q2 supplement reports USD 8,084 billion of Wealth Management client assets. That broad segment is not a disclosure of Singapore or Asia private-banking assets.

The firm’s Asia private-wealth page identifies Morgan Stanley Bank Asia Limited and its regional operations. It is a mistake to attach the USD 8,084 billion total to that Asian entity. The ledger includes the number to make the boundary visible, not to rank MSBAL above other banks in Singapore.

Can These Two AUM Numbers Actually Be Compared?

Matching currencies is only the first test. A USD regional invested-assets balance and a USD global private-bank client-assets balance can sit neatly next to each other while answering different questions. The same is true of two CHF balances when one belongs to Wealth Management and the other to a broader group.

The checker below compares the disclosed fields, not the banks’ suitability. It deliberately produces no winner, safety score or recommendation. A favourable match means fewer reporting differences to investigate, not that the institutions offer identical services.

What a Billion of AUM Does Not Tell You About Your Account

AUM measures a client-asset relationship. It is not the bank’s equity, an amount available to absorb losses or a promise that every client asset receives the same protection.

A deposit, a custody holding and a discretionary portfolio create different relationships. A portfolio can lose value even if the bank is financially sound. A custody arrangement requires its own questions about the legal holder, sub-custodians, asset treatment and transfer procedures. Credit secured on investments adds further contractual and market risks.

Ask for the exact contracting entity and the documents that govern the service. A branch, subsidiary, investment adviser and asset manager can share a familiar brand without being interchangeable counterparties. Capital ratios and credit ratings must likewise be attached to a dated legal entity, rather than pasted onto a global logo.

This is why the guide does not manufacture a safety ranking from AUM. Nor does it use an arbitrary scorecard to declare which institution is best for a family office. Our history of Singapore’s banking system explains how the centre developed; selecting a current account still requires institution-specific due diligence.

A Better Shortlist Starts With the Mandate

Consider two illustrative families, each with USD 15 million available to place. One holds a concentrated listed-company position and needs carefully structured liquidity. The other wants a conservative multi-currency portfolio, no borrowing and clear succession arrangements.

The same AUM ranking cannot resolve both briefs. The first family needs answers on eligible collateral, concentration limits, currency haircuts and the consequences of a price fall. The second needs clarity on investment discretion, custody, reporting and how its legal advisers will work with the bank. These are hypothetical profiles, not claims about actual client outcomes.

Before comparing brands, write down what the account must do, what assets will move and which requirements are non-negotiable. Then ask each institution to respond to the same brief. That creates a comparison the public league tables cannot provide.

Published minimums also require care. Priority banking, affluent wealth services and a private-bank relationship are different propositions. A threshold from a lower service tier should not be copied into a private-bank table. For a non-resident, citizenship, tax residence, structure, source of wealth and intended investment activity can change the review even when the assets are substantial.

Our Singapore non-resident banking guide covers that eligibility question separately. This article’s job is narrower: to make the scale evidence usable without disguising its limitations.

How to Reuse These Figures Without Repeating the Errors

When citing a balance, carry five fields into the sentence: institution, asset definition, geographical or business scope, reporting currency and date. Link the original disclosure. If the figure is preliminary, rounded or only a lower bound, retain that qualification.

A defensible citation would say: UBS reported USD 790 billion of Asia-Pacific GWM invested assets at 30 June 2026. It would not say: UBS manages USD 790 billion in Singapore. For Bank of Singapore, use above USD 145 billion in its 2025 annual review, not an exact 2026 number extrapolated from its growth rate.

The editorial calculations here are reproducible: UBS’s regional proportion uses 790 divided by 4,942; DBS’s reported-balance increase uses 516 divided by 365 minus one; the four CHF growth rates use June balances divided by their December baselines minus one. None is a client return, market-share calculation or measure of bank safety.

The next meaningful update will require the same discipline. When year-end results arrive, compare each business against its own earlier perimeter before declaring that a bank has gained ground. An acquisition, a reclassification and a strong market can all produce a larger balance. Only the supporting disclosure tells you which story the number represents.
