Investment banking is one of the most important parts of the global financial system, yet it is also one of the most commonly misunderstood areas of banking.
When most people hear the word “bank,” they think about savings accounts, credit cards, mortgages, fixed deposits and personal loans. These are primarily services associated with retail and commercial banking.
Investment banking operates very differently.
Instead of focusing mainly on helping individuals deposit, save or borrow money, investment banking primarily helps companies, governments, institutions and business owners raise capital, execute major transactions and obtain strategic financial advice.
An investment bank may help a growing company raise hundreds of millions of dollars, advise a business owner who wants to sell a company, assist two corporations with a merger, structure a major debt financing exercise or help a private company become publicly listed.
At its core, investment banking connects businesses and institutions that need capital or strategic advice with investors and financial markets.
A simplified description is:
Companies Need Capital or Strategic Advice → Investment Bank Structures the Transaction → Investors Provide Capital or Buyers Complete the Transaction
Investment banking therefore plays a central role in mergers and acquisitions, capital raising and the movement of money throughout the global economy.
What Does an Investment Bank Do?
Investment banks provide several types of financial and advisory services.
Some of the most important include:
- Mergers and acquisitions
- Initial public offerings
- Equity capital raising
- Debt capital raising
- Corporate restructuring
- Strategic financial advisory
- Business valuation
- Transaction execution
- Institutional securities activities
Different investment banks have different capabilities.
Large international investment banks may provide almost all of these services across numerous countries and industries.
Smaller boutique investment banks may specialise in one area, such as mergers and acquisitions.
The common characteristic is that investment banking generally focuses on large, complex corporate financial transactions.
Investment Banking Versus Normal Banking
The easiest way to understand investment banking is to compare it with conventional banking.
A retail bank serves individual customers.
Someone might approach a retail bank because they want to:
Open a savings account.
Obtain a credit card.
Take a housing loan.
Place money into a fixed deposit.
Transfer money overseas.
An investment banking client has very different requirements.
A company might approach an investment bank because it wants to:
Raise S$500 million.
Acquire a competitor.
Sell the business.
List shares on a stock exchange.
Issue bonds.
Restructure substantial debt.
Investment banking is therefore much more focused on corporate transactions and capital markets.
The Three Major Areas of Investment Banking
Although investment banks provide many services, much of traditional investment banking can be understood through three major areas:
Mergers & Acquisitions
Equity Capital Markets
Debt Capital Markets
Understanding these three areas provides a strong foundation for understanding the industry.
What Are Mergers and Acquisitions?
Mergers and acquisitions, commonly abbreviated as M&A, involve companies buying, selling or combining with other businesses.
Suppose Company A wants to acquire Company B for S$500 million.
This transaction could be extremely complicated.
Company A needs to determine:
What is Company B worth?
How much should we offer?
How should we finance the acquisition?
What financial risks exist?
How should the transaction be structured?
How should negotiations be conducted?
An investment bank may advise Company A throughout the process.
Alternatively, Company B may hire an investment bank to represent its shareholders and obtain the best possible transaction.
Investment bankers can therefore work for either the buyer or seller.
Sell-Side M&A
Imagine an entrepreneur has spent 25 years building a successful company.
The business now generates S$50 million in annual revenue and several million dollars in profit.
The founder decides it is time to retire.
But selling a company is much more complicated than selling shares on a stock exchange.
The entrepreneur needs to identify potential buyers.
The business needs to be valued.
Financial information needs to be prepared.
Potential buyers must be approached.
Offers must be compared.
Negotiations must take place.
Due diligence needs to be managed.
The final transaction needs to be structured.
An investment bank or M&A adviser may coordinate much of this process.
The process might look like:
Prepare Business → Identify Buyers → Contact Buyers → Receive Offers → Negotiate → Due Diligence → Final Agreement → Complete Sale
For an entrepreneur, this could be one of the largest financial transactions of his or her life.
Buy-Side M&A
Investment banks also advise companies that want to acquire other businesses.
Suppose a Singapore company wants to expand into another Asian market by acquiring a competitor.
The investment bank may help identify potential acquisition targets.
It may analyse the financial performance of those businesses.
It may estimate appropriate valuations.
It can help negotiate with sellers and structure the transaction.
The bank may also assist with financing.
The investment bank therefore functions as a strategic financial adviser during the acquisition process.
How Are Companies Valued?
Valuation is a major component of investment banking.
Before a company can be bought, sold or listed, investors need some idea of what it is worth.
Investment bankers may use several valuation methods.
Comparable Company Analysis
The company is compared with similar publicly listed companies.
For example, if similar companies trade at certain multiples of revenue or earnings, these multiples may provide a reference point.
Precedent Transaction Analysis
Investment bankers examine previous acquisitions involving similar companies.
If comparable businesses were sold at particular valuation multiples, those transactions may help determine an appropriate range.
Discounted Cash Flow Analysis
A discounted cash flow model estimates the future cash generated by the company and converts those future cash flows into a present value.
This is commonly known as a DCF analysis.
No valuation method produces a perfectly objective answer.
Investment bankers therefore often use several methods to establish a reasonable valuation range.
What Is an IPO?
Another important investment banking service is the Initial Public Offering, or IPO.
An IPO occurs when a private company offers shares to public investors and becomes publicly listed.
Imagine a successful private company worth approximately S$2 billion.
The founders and investors may decide to list the company on a stock exchange.
An investment bank can help coordinate this process.
The bank may assist with:
Financial preparation,
valuation,
regulatory documentation,
investor presentations,
marketing,
share pricing,
and distribution of shares to investors.
After the IPO, shares can generally be traded through the relevant stock exchange.
The company has therefore transitioned from:
Private Company → IPO → Publicly Listed Company
Why Do Companies Go Public?
Companies pursue IPOs for several reasons.
One major reason is raising capital.
A company may need hundreds of millions of dollars to expand.
Instead of borrowing all the money, it can sell ownership interests to investors.
For example, a company valued at S$1 billion might sell 20% of its equity to public investors.
In simplified terms, this could potentially raise approximately S$200 million before considering transaction structure, pricing, fees and other factors.
That capital could then be used to:
Build new facilities.
Expand internationally.
Acquire competitors.
Develop products.
Repay debt.
Strengthen the balance sheet.
An IPO can also create liquidity for existing shareholders, although restrictions may apply to how and when insiders can sell their shares.
What Are Equity Capital Markets?
The part of investment banking focused on raising money through shares is generally known as Equity Capital Markets, or ECM.
An IPO is one example.
However, already-listed companies may also raise additional equity.
Suppose a publicly traded company wants S$300 million to fund an acquisition.
Instead of borrowing the entire amount, the company could potentially issue additional shares.
Investment banks help structure and distribute these transactions.
The basic relationship is:
Company Needs Capital → Shares Are Issued → Investors Buy Shares → Company Receives Capital
The advantage is that equity does not normally require contractual interest payments like debt.
The disadvantage is that existing shareholders may experience dilution because additional ownership interests have been issued.
What Are Debt Capital Markets?
Companies do not always want to sell additional shares.
Sometimes they prefer borrowing.
Investment banks can help companies and governments raise capital through debt securities such as bonds.
This area is generally known as Debt Capital Markets, or DCM.
Imagine a large corporation needs S$1 billion.
Instead of borrowing the entire amount through conventional bank loans, it might issue bonds.
Institutional investors purchase the bonds and effectively lend money to the company.
The company agrees to pay interest and repay the principal according to the terms of the bonds.
The process can be simplified as:
Company Issues Bonds → Investors Provide Capital → Company Pays Interest → Principal Eventually Repaid
Investment banks can help determine the appropriate bond structure, maturity, interest terms, investor targeting and issuance strategy.
Debt Versus Equity Financing
One of the fundamental questions in corporate finance is whether a company should raise money through debt or equity.
Suppose a company needs S$100 million.
Option 1: Debt
The company borrows S$100 million.
Existing shareholders retain their ownership percentages.
However, the company must pay interest and eventually repay the debt.
Option 2: Equity
The company sells S$100 million worth of new shares.
There may be no contractual repayment requirement.
However, existing shareholders now own a smaller percentage of the company.
Investment bankers help companies evaluate these trade-offs.
In practice, many businesses use a combination of debt and equity.
Investment Banking and Private Equity
Investment banking and private equity are closely connected but fundamentally different businesses.
An investment bank advises on transactions.
A private equity firm invests capital into businesses.
Consider an entrepreneur who wants to sell a S$100 million company.
The investment bank might advise the entrepreneur and organise the sale process.
The private equity firm might be one of the potential buyers.
Therefore:
Investment Bank = Adviser / Intermediary
Private Equity Firm = Investor / Owner
Investment bankers may introduce the company to private equity funds and strategic corporate buyers.
The private equity firms then decide whether they want to invest their own managed capital.
Investment Banking and Wealth Management
Investment banking should also not be confused with wealth management.
Wealth management generally serves affluent individuals and families.
Its focus may include:
- Investment portfolios
- Financial planning
- Wealth preservation
- Financing
- Retirement
- Succession
- Legacy planning
Investment banking generally serves companies, governments and institutional clients.
Its focus is more commonly:
- M&A
- IPOs
- Equity raising
- Bond issuance
- Corporate restructuring
However, the two areas can intersect.
Imagine an entrepreneur sells a business for S$50 million through an M&A transaction.
An investment bank may advise on the business sale.
After receiving the proceeds, the entrepreneur may require private banking and wealth-management services to invest and preserve the S$50 million.
Therefore, the client’s journey might be:
Build Business → Investment Bank Helps Sell Business → Entrepreneur Receives Liquidity → Private Bank Manages Personal Wealth
This is an important connection between corporate finance and personal wealth management.
Investment Banking Versus Private Banking
The names sound similar, but investment banking and private banking serve very different purposes.
Private banking is primarily designed for wealthy individuals.
Investment banking is primarily designed for corporations and institutions.
A private banker might help a wealthy client manage a S$10 million portfolio.
An investment banker might help that client’s company raise S$500 million or sell itself to another corporation.
Private banking asks:
“How should we manage your personal wealth?”
Investment banking asks:
“How should we execute this corporate transaction?”
What Is Corporate Restructuring?
Investment banks may also advise companies experiencing financial difficulties.
Suppose a company has:
S$500 million of debt,
declining revenue,
limited cash,
and significant upcoming repayments.
The company may not be able to meet all its obligations.
Investment bankers specialising in restructuring can help evaluate possible solutions.
These might involve:
Renegotiating debt.
Extending maturities.
Raising additional capital.
Selling assets.
Exchanging debt for equity.
Selling the company.
The objective is generally to create a financially sustainable structure while balancing the interests of different stakeholders.
Who Uses Investment Banks?
Investment banking clients can include:
- Large corporations
- Mid-sized businesses
- Governments
- Government-linked entities
- Private equity firms
- Institutional investors
- Business owners
- Family-owned companies
- High-growth companies
Not every transaction involves a multibillion-dollar corporation.
Smaller investment banks and corporate-finance advisers may work with privately owned businesses on transactions worth tens of millions of dollars or less.
This can be particularly relevant to entrepreneurs planning succession or business exits.
What Are Boutique Investment Banks?
Not all investment banks are enormous global institutions.
There are also boutique investment banks.
These firms may specialise in:
M&A,
particular industries,
specific geographical markets,
or mid-market transactions.
For example, a boutique adviser might focus entirely on selling technology companies in Southeast Asia.
Another might specialise in healthcare acquisitions.
Boutiques may have smaller teams but substantial expertise within their chosen niches.
For a business owner selling a company, the most suitable adviser is not necessarily the largest investment bank.
Industry knowledge, buyer relationships, transaction experience and senior-level attention can all be important considerations.
How Do Investment Banks Make Money?
Investment banks earn fees for providing financial and advisory services.
For M&A transactions, the bank may receive an advisory fee.
Part of the fee may depend on whether the transaction successfully completes.
For capital raising, banks may earn underwriting or placement fees.
Other activities may generate additional revenue.
For example, imagine an investment bank advises on the S$500 million sale of a company.
If the agreed transaction fee were 1%, the fee would theoretically be S$5 million.
Actual investment banking fee structures vary substantially depending on transaction size, complexity, market conditions and the services provided.
What Is Underwriting?
Underwriting is another important investment banking concept.
When a company issues shares or bonds, investment banks can help distribute those securities to investors.
In certain transactions, banks may agree to purchase securities from the issuer and then resell them to investors, subject to the terms of the underwriting arrangement.
This creates a bridge between companies seeking capital and investors looking for investment opportunities.
The bank’s reputation and distribution capabilities can therefore be important when executing large capital-market transactions.
Who Buys the Securities?
Investment banks maintain relationships with institutional investors.
These can include:
- Asset managers
- Pension funds
- Insurance companies
- Hedge funds
- Sovereign wealth funds
- Family offices
- Other professional investors
Suppose a company wants to issue S$2 billion of bonds.
The investment banks involved may market the bonds to institutional investors around the world.
If demand is strong, the transaction may be completed on attractive terms.
If investor demand is weak, pricing may need to become more attractive to buyers.
Investment banking therefore connects corporate capital demand with institutional investment capital.
Investment Banking in Singapore
Singapore is a major financial centre in Asia and an important location for investment banking activities.
Businesses operating across Southeast Asia may use Singapore-based financial institutions and professional advisers for:
Mergers and acquisitions,
capital raising,
cross-border transactions,
debt issuance,
equity transactions,
and strategic financial advisory.
Singapore’s position as a regional business hub also means many transactions involve multiple jurisdictions.
For example, a Singapore-based company might acquire a business in Indonesia, Vietnam or Malaysia.
Alternatively, an international corporation might acquire a Singapore business as part of its expansion into Southeast Asia.
Investment banks can play an important role in coordinating the financial aspects of these cross-border transactions.
Investment Banking for Entrepreneurs
Investment banking becomes particularly relevant when entrepreneurs reach a major transition point.
Imagine someone starts a business at age 30.
Over 20 years, the company grows:
S$1 million revenue
→ S$5 million
→ S$20 million
→ S$50 million
→ S$100 million.
The founder eventually decides to sell.
At this stage, the company may represent the majority of the entrepreneur’s personal net worth.
The investment banking process can help convert that illiquid business wealth into liquid financial wealth.
This transition is extremely important.
Before the sale:
Entrepreneur’s Wealth = Primarily Business Ownership
After the sale:
Entrepreneur’s Wealth = Cash + Investments + Other Assets
The financial problem then changes completely.
Before the transaction, the entrepreneur’s focus may be business growth.
Afterward, the focus may shift toward investment management, capital preservation and succession.
Investment Banking and the Wealth Journey
Investment banking can therefore sit at an interesting point within the broader process of wealth creation.
An entrepreneur’s journey might look like:
Start Business → Grow Business → Increase Company Value → Raise Capital → Expand → Sell or IPO → Create Liquidity → Wealth Management → Wealth Preservation → Wealth Transfer
Investment bankers may become involved during the fundraising, acquisition, IPO or business-sale stages.
Private bankers and wealth managers may become more important after substantial personal liquidity has been created.
Private equity can appear at several stages as either an investor in the company or a potential buyer.
Understanding these relationships makes the financial industry much easier to navigate.
Is Investment Banking Only for Huge Companies?
No.
The largest global investment banks naturally focus heavily on major corporations and billion-dollar transactions.
However, a substantial middle market also exists.
A privately owned Singapore company worth S$20 million, S$50 million or S$100 million may potentially work with an M&A adviser, corporate-finance adviser or boutique investment bank when raising capital or selling the business.
Therefore, investment banking principles are relevant not only to multinational corporations but also to successful privately owned businesses.
Investment Banking Is Primarily Transaction Driven
Another major difference between investment banking and wealth management is the nature of the relationship.
Wealth management is generally a long-term relationship.
A client may remain with a private bank for decades.
Investment banking is often transaction driven.
A company may hire an investment bank specifically to complete:
An acquisition.
A business sale.
An IPO.
A bond issue.
A capital raising exercise.
Once the transaction is completed, the immediate engagement may end, although large companies frequently maintain ongoing relationships with several investment banks.
Why Investment Banking Matters
Investment banking performs an important economic function because capital does not automatically flow to the companies that need it.
Businesses need financial intermediaries capable of connecting them with investors.
Entrepreneurs also need advisers when selling businesses.
Corporations need financial expertise when acquiring competitors.
Governments and companies need access to debt markets.
Private businesses need assistance when entering public markets.
Investment banks help facilitate these activities.
In this sense, investment banking acts as part of the infrastructure connecting:
Businesses + Investors + Capital + Financial Markets
Without these connections, raising large amounts of capital and completing complex corporate transactions would be significantly more difficult.
Conclusion
So, what is investment banking?
Investment banking is a specialised area of finance that helps companies, governments, institutions and business owners raise capital and execute major financial transactions.
Its principal activities include:
Mergers & Acquisitions + IPOs + Equity Capital Markets + Debt Capital Markets + Corporate Restructuring + Strategic Advisory
Investment banking is fundamentally different from conventional retail banking.
Retail banking helps individuals manage everyday financial requirements.
Private banking helps wealthy individuals manage personal wealth.
Wealth management focuses on building, managing, preserving and eventually transferring wealth.
Private equity invests directly into businesses.
Investment banking, by comparison, helps facilitate transactions between businesses, investors and capital markets.
One useful way to remember the differences is:
Commercial Banking = Deposits and Loans
Wealth Management = Managing Personal Wealth
Private Banking = Banking for High-Net-Worth Individuals
Investment Banking = Corporate Transactions and Capital Raising
Private Equity = Investing in and Owning Private Businesses
For entrepreneurs, investment banking can become particularly important when the business reaches a major financial milestone.
The founder may want to raise capital, acquire competitors, bring in investors, sell part of the company or exit the business entirely.
An investment bank or corporate-finance adviser can help structure and execute these transactions.
A successful transaction may then transform the entrepreneur’s financial position.
Years of business building can culminate in a major liquidity event, converting concentrated business ownership into financial assets that subsequently require professional wealth management.
Investment banking therefore occupies an important position in the financial ecosystem.
It connects companies requiring capital with investors who possess capital.
It connects business sellers with potential buyers.
It connects private companies with public markets.
And, in many cases, it provides the financial bridge between building a valuable business and eventually converting that business value into personal wealth.
