When discussing wealth management, private banking, investment funds or asset management, one abbreviation appears repeatedly: AUM.

AUM stands for Assets Under Management.

At its simplest, AUM refers to the total market value of financial assets that a bank, investment manager, wealth manager, fund or other financial institution manages on behalf of its clients.

For example, if an investment management company manages S$5 billion of client investments, the company may be described as having approximately S$5 billion in AUM.

The concept sounds straightforward, but AUM is extremely important within the financial industry. It can indicate the scale of an asset manager, determine the fees generated by an investment business, influence a client’s eligibility for certain wealth-management services and provide an indication of how much capital investors have entrusted to a financial institution.

For individuals using wealth-management services, understanding AUM is also important because banks frequently use a related concept—assets under management with the bank—when determining whether a client qualifies for premier banking, priority banking or private banking.

However, having a net worth of S$5 million does not necessarily mean having S$5 million of AUM with a bank.

Understanding this distinction is essential.

What Does AUM Mean?

AUM stands for:

Assets Under Management

It represents the value of assets being managed by a financial institution or investment professional.

Depending on the organisation, AUM might include assets such as:

• Cash
• Bonds
• Shares
• Exchange-traded funds
• Unit trusts
• Mutual funds
• Managed portfolios
• Alternative investments
• Certain structured investments
• Other eligible investment assets

The precise calculation can differ between institutions.

For example, some institutions may include certain cash balances when calculating client AUM, while others may distinguish between investment assets and total relationship balances.

Therefore, when comparing AUM figures or banking requirements, it is important to understand exactly what is included.

A Simple Example of AUM

Imagine a wealth-management company has 100 clients.

Suppose the average client has S$1 million invested through the company.

The firm’s approximate AUM would be:

100 clients × S$1 million = S$100 million AUM

If the investments subsequently increase in value by 10%, assuming there are no withdrawals or additional deposits, the firm’s AUM could rise to approximately:

S$110 million

Similarly, if markets decline significantly, the firm’s AUM may fall even though no clients withdraw money.

This demonstrates an important characteristic of AUM.

AUM can change because of both investment performance and client money movements.

How Does AUM Increase?

There are several major ways an investment manager’s AUM can increase.

New Clients

If additional investors place money with the institution, AUM increases.

For example, an asset manager with S$1 billion of AUM that attracts S$100 million from new investors could increase its AUM to approximately S$1.1 billion, assuming market values remain unchanged.

Existing Clients Invest More

Existing clients may transfer additional capital into their portfolios.

A private banking client might initially place S$2 million with a bank and later transfer another S$1 million.

The client’s AUM relationship with the bank could therefore increase.

Investment Performance

If investments appreciate, AUM may rise automatically.

Suppose a fund manages S$500 million.

If the underlying portfolio increases by 8%, the fund’s AUM could rise to approximately S$540 million before considering investor subscriptions, withdrawals and fees.

Business Acquisitions

Asset-management firms sometimes acquire other investment managers or portfolios.

If a firm managing S$10 billion acquires another manager with S$2 billion in AUM, the combined organisation could potentially manage approximately S$12 billion, subject to client retention and the structure of the transaction.

How Does AUM Decrease?

The reverse can also occur.

AUM may fall because clients withdraw money.

It can also fall because investment markets decline.

Consider an investment fund with S$1 billion in assets.

If markets decline by 20%, its assets might fall to approximately S$800 million even if investors do not withdraw anything.

If investors simultaneously withdraw another S$100 million, the reduction becomes even larger.

This is why asset-management companies closely monitor both:

Investment Performance

and

Net Fund Flows

Net flows represent the difference between new money entering and money leaving.

Why Is AUM Important?

AUM is one of the most widely used measurements of scale in the wealth and investment-management industry.

If one investment company manages S$500 million while another manages S$500 billion, the organisations operate at dramatically different scales.

Large AUM can potentially provide advantages.

These may include:

• Greater operating scale
• Larger research teams
• More investment resources
• Broader product offerings
• Greater institutional infrastructure
• Stronger negotiating power with service providers

However, larger AUM does not automatically mean better investment performance.

A small specialist fund may outperform a very large fund.

Similarly, an enormous bank does not automatically provide better personalised service than a smaller wealth manager.

AUM should therefore be considered one indicator rather than a complete measure of quality.

AUM in Wealth Management

AUM is particularly important in wealth management.

Banks often segment customers according to the amount of eligible assets they maintain with the institution.

A simplified banking hierarchy might look like:

Retail Banking → Premier Banking → Private Banking → Ultra-High-Net-Worth Services

Each level may have different eligibility requirements.

For example, a bank might require a client to maintain a particular level of qualifying assets to enter its premier banking segment.

Private banking usually requires substantially higher assets.

The actual thresholds vary considerably between banks, jurisdictions and programmes.

Therefore, clients should always check the latest requirements directly with the relevant financial institution.

AUM Versus Net Worth

One of the most common misunderstandings is assuming that AUM and net worth are the same.

They are not.

Net worth measures the overall financial value of an individual.

A simplified formula is:

Net Worth = Total Assets − Total Liabilities

AUM, meanwhile, generally refers to the assets managed by a particular financial institution or investment manager.

Consider an entrepreneur with:

S$8 million business value

S$4 million property

S$2 million investment portfolio

S$500,000 cash

S$2 million total debt

The entrepreneur’s approximate net worth would be:

S$14.5 million assets − S$2 million liabilities = S$12.5 million net worth

However, suppose only S$1.5 million of the investment portfolio and cash is held with a particular bank.

The entrepreneur might have a net worth of approximately S$12.5 million but only around S$1.5 million of eligible assets with that bank.

Therefore:

Net Worth ≠ AUM

This distinction is particularly important when considering private banking.

A wealthy business owner may have a very high net worth while having relatively limited liquid investable assets.

AUM Versus Investable Assets

Another important concept is investable assets.

Investable assets generally refer to financial assets that can potentially be invested through banks, brokers or investment managers.

These may include:

• Cash
• Shares
• Bonds
• Investment funds
• Marketable securities
• Certain alternative investments

A person’s primary residence may contribute significantly to net worth but would generally not function like a liquid investment portfolio held under wealth management.

Similarly, the value of a privately owned business can make an entrepreneur extremely wealthy without creating equivalent liquid investable assets.

For this reason, wealth-management institutions often pay particular attention to liquid or investable wealth.

AUM and Private Banking

Private banking is generally designed for high-net-worth individuals with substantial investable assets.

Suppose an entrepreneur has a net worth of S$20 million.

The wealth might consist of:

S$15 million business ownership

S$3 million property equity

S$1 million cash

S$1 million investment portfolio

Although the individual is clearly wealthy, only around S$2 million is represented by cash and investments in this simplified example.

Depending on the bank’s criteria, this may affect eligibility for a particular private-banking programme.

Now imagine the entrepreneur sells part of the company and receives S$10 million in cash.

Suddenly, the individual’s investable assets increase substantially.

At that point, private banking and more sophisticated wealth-management services may become significantly more relevant.

This is why business exits frequently represent an important transition point in an entrepreneur’s financial journey.

What Does AUM Mean for a Bank?

For a bank or wealth manager, AUM represents more than client wealth.

It also represents a potential source of revenue.

Many wealth-management businesses generate revenue from fees associated with managing or servicing client assets.

Depending on the business model, revenue may come from:

• Management fees
• Advisory fees
• Investment product fees
• Trading commissions
• Custody fees
• Platform fees
• Financing income
• Foreign-exchange transactions
• Other banking services

The greater the AUM, the larger the potential revenue base.

This is one reason banks compete intensely for affluent and high-net-worth clients.

AUM-Based Fees

Many investment managers charge fees based on a percentage of AUM.

Suppose a portfolio manager oversees S$10 million for a client and charges an annual management fee of 1%.

The approximate annual management fee would be:

S$10 million × 1% = S$100,000

If the portfolio increases to S$12 million, the same 1% fee would equal approximately S$120,000.

If the portfolio falls to S$8 million, it would equal approximately S$80,000.

This creates a relationship between the size of the client’s portfolio and the investment manager’s revenue.

Actual fee structures can be considerably more complicated and may include different tiers, performance fees, transaction charges and product-level expenses.

AUM and Asset Management Companies

For an asset-management company, AUM is one of its most important business metrics.

Imagine two fund managers.

Manager A oversees S$100 million.

Manager B oversees S$50 billion.

Even if both charge similar percentage fees, Manager B potentially has a dramatically larger revenue base.

This explains why asset-management firms spend substantial resources attracting and retaining investor capital.

The industry’s business model often depends on:

Investment Performance + Client Acquisition + Client Retention = AUM Growth

If investors are satisfied and portfolios perform well, assets may increase.

If performance is poor or clients lose confidence, withdrawals can reduce AUM.

Is Higher AUM Always Better?

Not necessarily.

A high AUM demonstrates scale, but it does not automatically demonstrate investment skill.

In certain investment strategies, becoming too large can actually create challenges.

A small fund might be able to invest efficiently in smaller companies or niche opportunities.

A fund managing tens of billions of dollars may be unable to allocate meaningful amounts to those opportunities without affecting market prices.

Large AUM can therefore be beneficial operationally while potentially limiting flexibility in certain investment strategies.

Investors should evaluate factors beyond AUM, including:

• Investment philosophy
• Historical performance
• Risk management
• Fees
• Team experience
• Transparency
• Portfolio composition
• Liquidity
• Suitability

AUM and Investment Performance

AUM should also not be confused with investment performance.

Suppose Fund A has S$100 billion in AUM and Fund B has S$1 billion.

The fact that Fund A is 100 times larger does not mean its investment returns will be better.

AUM measures how much money is managed.

Performance measures how effectively that money has performed over a particular period.

They are fundamentally different measurements.

A large fund may have accumulated substantial AUM because it has existed for decades, belongs to a major financial institution or attracts institutional investors.

Investment decisions should therefore never be based solely on AUM.

AUM and Relationship Managers

Within wealth banking, relationship managers may be responsible for a portfolio of clients and their associated assets.

For example, a relationship manager might serve 100 affluent clients collectively holding S$200 million with the bank.

The manager’s role may involve:

• Maintaining client relationships
• Understanding financial objectives
• Coordinating investment solutions
• Identifying financing requirements
• Introducing relevant specialists
• Supporting wealth-planning discussions
• Retaining client assets

From the bank’s perspective, maintaining AUM is important because clients can transfer assets to competing institutions.

This creates strong competition among banks for wealthy clients.

Can a Client Have AUM With Multiple Banks?

Yes.

High-net-worth individuals frequently maintain relationships with multiple banks.

For example, someone might have:

S$3 million with Bank A,

S$2 million with Bank B,

S$1 million with Bank C,

and S$500,000 with an investment platform.

The individual has approximately S$6.5 million distributed across different institutions.

But Bank A may only view the S$3 million held within its relationship when determining service eligibility and benefits.

This explains why banks may encourage clients to consolidate assets.

A larger relationship can potentially provide the client with access to higher service tiers or additional banking capabilities, depending on the institution.

AUM and Wealth Financing

AUM can also be relevant to wealth financing.

Financial assets held with a bank may potentially be used as collateral for certain credit facilities.

For example, a private banking client with a diversified investment portfolio might be eligible for securities-backed lending.

Instead of selling investments to obtain liquidity, the client may potentially borrow against eligible securities.

This is sometimes referred to as:

Lombard lending

or

securities-backed financing.

However, not every dollar of AUM can necessarily be borrowed against.

Banks assign different lending values to different assets depending on factors such as volatility, liquidity, credit quality and concentration.

Leverage also introduces substantial risks, including the possibility of collateral calls if investment values decline.

AUM and Wealth Accumulation

AUM can also provide a useful way of thinking about progress during the wealth-accumulation stage.

Consider an investor who starts with S$50,000.

Over time, the portfolio grows:

S$50,000

→ S$100,000

→ S$250,000

→ S$500,000

→ S$1 million

→ S$2 million

→ S$5 million

As investable assets increase, the individual’s banking requirements may evolve.

Initially, a basic brokerage account might be sufficient.

Later, premier banking may become useful.

As financial assets become substantially larger and more complex, private banking or professional wealth-management services may become relevant.

Therefore, AUM can indirectly influence the type of financial services an individual requires.

AUM and Family Offices

At very high levels of wealth, families may establish or engage family offices.

The scale of assets involved can be substantial.

A family office might oversee investments across:

• Public equities
• Bonds
• Private equity
• Venture capital
• Real estate
• Private credit
• Businesses
• Cash
• Alternative investments

In these situations, understanding total assets under management becomes important for investment governance, risk management and portfolio reporting.

The family is no longer simply managing an investment account.

It may effectively be managing a sophisticated investment organisation.

Why Singapore Is Important for AUM

Singapore has developed into a major wealth-management and asset-management centre.

Banks, private banks, asset managers, family offices and investment firms use Singapore as a base for managing capital from both Singapore and international investors.

For affluent individuals, this creates access to a broad financial ecosystem that can include:

Private banking,

investment management,

wealth planning,

financing,

foreign exchange,

insurance,

trust-related services,

and family-office solutions.

As wealth in Asia continues to develop, AUM has become an increasingly important measure of the scale of Singapore’s wealth-management industry.

AUM Should Not Be the Only Consideration

While AUM is useful, clients should avoid choosing a wealth manager simply because the institution manages the most money.

A client should also consider:

Service quality

Is the relationship manager responsive and knowledgeable?

Investment capabilities

Does the institution provide appropriate investment solutions?

Risk management

How does the organisation manage investment and operational risks?

Fees

Are costs transparent and reasonable?

Product access

Does the bank provide the investments and markets the client requires?

Financing

Are suitable credit solutions available?

International capabilities

Can the institution support assets and transactions across different countries and currencies?

AUM tells you about scale.

It does not tell you everything about quality.

Understanding AUM Within the Wealth Journey

AUM becomes easier to understand when viewed within the broader process of building wealth.

A simplified journey might look like:

Income → Savings → Investments → Wealth Accumulation → Growing AUM → Wealth Management → Wealth Preservation → Wealth Transfer

During the early stages, the individual’s main objective is accumulating assets.

As those assets increase, more of them may come under professional management.

Eventually, the size and complexity of the portfolio may justify premier banking, private banking or family-office services.

This is why AUM frequently appears when discussing wealth-management eligibility.

It represents the pool of financial assets that can potentially be professionally managed.

Conclusion

So, what is AUM?

AUM stands for Assets Under Management.

It generally refers to the total value of assets that a financial institution, investment manager, wealth manager or fund manages on behalf of clients.

For investment companies, AUM is an important measure of business scale.

For banks, AUM can represent the amount of client assets within their wealth-management ecosystem.

For individuals, the amount of eligible assets maintained with a bank may influence access to different banking tiers and services.

However, one of the most important distinctions to understand is:

AUM is not the same as net worth.

A person could have a net worth of S$20 million because they own a valuable company and several properties while maintaining only S$2 million of liquid investments with a bank.

Conversely, another individual might have S$10 million invested through a wealth manager and therefore have a much larger AUM relationship despite having a lower overall net worth.

AUM should also not be confused with investment performance.

A financial institution managing hundreds of billions of dollars is not automatically better than a smaller investment manager.

Instead, AUM primarily tells us how much capital is being managed.

For individuals progressing through the different stages of wealth creation, AUM can become increasingly relevant.

The financial journey may begin with earning and saving, progress toward investing and wealth accumulation, and eventually develop into more sophisticated wealth management, financing, preservation and succession planning.

In that broader journey, AUM provides an important measurement of the financial assets that have reached the stage where they can be professionally managed.

Put simply:

Net Worth tells you approximately how wealthy someone is.

Investable Assets tell you how much wealth can potentially be invested.

AUM tells you how much of those assets are actually being managed by a particular institution or investment manager.

Understanding these differences provides a much clearer picture of how modern wealth management, private banking and asset management work.
