What is Investment Banking?

Investment banking is a subsection of banking which specializes in assisting companies to obtain capital and helping in the financial aspects of mergers, acquisitions, and more. They do not interact with the general public or help with banking basics like managing savings or issuing loans. Rather, investment banks deal with substantial and intricate financial transactions.

In simple terms, investment banks serve as go-betweens for investors and businesses. They assist firms with complex tasks such as strategically issuing shares, bonds, and other securities while also providing valuable advice for optimizing business strategies during corporate growth or restructuring phases.

Key Characteristics of Investment Banking

High-level financial advisory

Capital raising through debt and equity

Mergers and acquisitions (M&A) advisory

Risk management and market research

Usually caters to corporates, governments, and high-net-worth individuals (HNIs)

Core Functions of Investment Banking

Let’s explore the main functions of investment banking in detail:

1. Capital Raising

One of the primary functions of investment banks is helping clients raise money. This can be done in several ways:

a) Equity Financing

Investment banks assist companies in issuing shares to the public through Initial Public Offerings (IPOs) or Follow-on Public Offerings (FPOs). They help determine the share price, manage regulatory filings, and market the shares to institutional and retail investors.

b) Debt Financing

Companies may also raise funds through debt instruments like bonds or debentures. Investment banks help structure the debt, get it rated, and sell it to potential investors.

2. Mergers and Acquisitions (M&A)

M&A is a high-stakes area where investment banks truly shine. They:

Identify potential merger or acquisition targets.

Conducting due diligence and valuation.

Negotiating deals.

Structure of payment terms (cash, stock, hybrid).

Handle regulatory and legal compliance.

Their goal is to ensure that both parties gain maximum value from the transaction while minimizing risks.

3. Underwriting

Underwriting is the process of guaranteeing the sale of securities. When a company goes public, the investment bank underwrites the deal, meaning it buys the shares from the company and resells them to the public, assuming the risk if the shares don’t sell.

There are two main types:

Firm Commitment: Bank takes full risk of unsold shares

Best Effort: Bank tries its best to sell but doesn’t guarantee

4. Advisory Services

Investment banks provide strategic and financial advice to their clients. These services include:

Business Valuation

Risk assessment

Corporate restructuring

IPO readiness‍

Debt restructuring

Their financial expertise helps companies make informed decisions during critical events like expansion, diversification, or crisis.

While investment banks advise on major transactions, they also engage in the sale and trading of securities for clients and themselves.

Institutional sales teams help large clients like pension funds and mutual funds buy and sell stocks, bonds, and derivatives.

Trading desks execute these trades and provide market liquidity.

Some investment banks also engage in proprietary trading, where they use their own funds to invest in the markets.

6. Asset Management

Many investment banks offer wealth and asset management services for high-net-worth individuals and institutional clients. They create customized portfolios based on client goals, risk tolerance, and market trends.

7. Research and Analysis

Investment banks have dedicated teams that conduct in-depth market research and equity analysis. Their insights are used for:

Guiding investment decisions

Publishing reports for clients

Supporting internal trading and advisory teams

Top-tier investment banks like Goldman Sachs and Morgan Stanley are known for their world-class research departments.
