# What Do Investment Banks Do? A Plain-English Overview Published: 2026-02-23 Author: Warren Team URL: https://www.heywarren.com/blog/what-do-investment-bank-do --- When Goldman Sachs helped Uber go public in 2019, the deal generated over $100 million in fees — in a single [transaction](/blog/what-is-a-transactions). Investment banks don't hold your savings or hand out car loans; they orchestrate the enormous machinery of global capital. If you've ever typed "what do investment bank do" into a search engine, you're asking a question most people can't answer clearly. Most people assume all banks work the same way — taking deposits, lending money, keeping the system running. That misunderstanding leaves investors and business owners with a serious blind spot about how markets actually work and how the biggest financial decisions on the planet get made. This guide explains exactly what investment banks do, how they make money, and why their activities ripple out to affect your portfolio. You'll walk away understanding the difference between [underwriting](/blog/what-is-underwriting) and advisory work, how a billion-dollar merger actually gets done, and what investment banking activity means for everyday investors. Global investment banking fees hit a record $132 billion in 2021, according to Dealogic — evidence that these institutions sit at the absolute center of how capital moves around the world. --- ## What Do Investment Banks Do? A Plain-English Overview Investment banks are financial intermediaries that help corporations, governments, and institutions raise capital, execute large-scale transactions, and navigate complex financial markets. Unlike commercial banks, they do not accept deposits from the public. Their core functions include underwriting securities offerings, advising on mergers and [acquisitions](/blog/what-is-acquisitions), facilitating trading, and providing strategic financial counsel to major organizations. The word "bank" is genuinely misleading here. Think of an investment bank less as a place to store money and more as a high-powered financial advisory and execution firm. When a company wants to raise $500 million by selling shares to the public, an investment bank structures the deal, sets the price, finds the buyers, and collects a fee — typically 3–7% of the total offering size. There are two broad tiers of investment banks: - **Bulge bracket banks** — giants like Goldman Sachs, JPMorgan, Morgan Stanley, and Citigroup — handle the largest global deals and maintain massive trading operations. - **Boutique investment banks** — smaller, specialized firms like Lazard or Evercore — focus on specific industries or deal types, often providing advisory services only without a trading arm. Both types serve the same core purpose: connecting organizations that need capital with the investors who have it, and helping large entities navigate transactions too complex to handle alone. Investment banking touches your life even if you've never worked with one directly. When a company you own stock in raises new capital, when a tech giant acquires a competitor, or when a government issues bonds to fund infrastructure — an investment bank almost certainly had a hand in it. --- ## The Core Services Investment Banks Provide Investment banks offer three primary service lines: [capital markets](/blog/capital-markets-def) (helping clients raise money by issuing stocks and bonds), mergers and acquisitions advisory (guiding deals between companies), and sales and trading (buying and selling securities on behalf of clients and the firm itself). Most large banks also provide equity research, asset management, and risk management services. ![The three core service lines offered by full-service investment banks, each generating distinct revenue streams.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20600%20211%22%20width%3D%22600%22%20height%3D%22211%22%20role%3D%22img%22%3E%3Ctitle%3EHierarchy%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%2220%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%2254%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22white%22%3EInvestment%20Bank%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20120%20105.5%20L%20120%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%2240%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22120%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ECapital%20Markets%3C%2Ftext%3E%3Ctext%20x%3D%22120%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EIPOs%20%26amp%3B%20bond%20issuance%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20300%20105.5%20L%20300%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EM%26amp%3BA%20Advisory%3C%2Ftext%3E%3Ctext%20x%3D%22300%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EMergers%20%26amp%3B%20acquisitions%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20480%20105.5%20L%20480%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22400%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22480%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ESales%20%26amp%3B%20Trading%3C%2Ftext%3E%3Ctext%20x%3D%22480%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EMarket-making%20%26amp%3B%20liquidity%3C%2Ftext%3E%3C%2Fsvg%3E) *The three core service lines offered by full-service investment banks, each generating distinct revenue streams.* ### Underwriting: Bringing Securities to Market Underwriting is one of the oldest and most essential functions in the industry. When a company decides to raise capital by issuing stock or bonds, it hires an investment bank to underwrite the offering. This means the bank agrees to purchase the entire issue at an agreed price and then resell it to investors — accepting the risk that it might not be able to move everything at the anticipated price. In an **initial public offering (IPO)**, the investment bank conducts due diligence, helps set the share price, files regulatory documents with the SEC, and builds a "book" of investor demand through a multi-city roadshow. This process typically takes three to six months and costs the issuing company 4–7% of the total capital raised. In 2021, investment banks underwrote over 1,000 IPOs globally, raising more than $600 billion in new equity capital — a record pace fueled by low interest rates and a booming stock market. ### Debt Capital Markets Investment banks also help companies and governments issue bonds. A **corporate bond offering** works similarly to an IPO: the bank structures the terms — maturity, interest rate, covenants — markets the bonds to institutional investors, and funnels the proceeds to the issuer. Governments rely on investment banks for **sovereign bond issuances** too. When a country needs to fund a budget deficit, it works with banks to price and distribute government bonds to global buyers. The [U.S. Treasury](https://home.treasury.gov/) works with a network of 24 primary dealer banks — including Goldman Sachs, JPMorgan, and Citigroup — to sell Treasury securities at every scheduled auction. --- ## How Investment Banks Generate Revenue Investment banks earn money through four main channels: advisory fees (typically 0.5–2% of deal value), underwriting spreads (the difference between what they pay for securities and what they sell them for), trading profits (gains on securities positions they hold), and asset management fees (a percentage of client assets). Each revenue stream behaves differently across economic cycles, which is why large banks diversify across all four. ### Advisory Fees When a company hires an investment bank to advise on a merger or acquisition, the bank earns a **success fee** — paid only when the deal actually closes. These fees range from 0.5% to 2% of total deal value for mid-size transactions, dropping toward 0.1% for mega-deals worth tens of billions. On a $10 billion merger, a 0.5% fee means $50 million for the bank. For a single deal. That dynamic makes M&A advisory among the most lucrative businesses in all of finance, with top bankers earning annual compensation well above $1 million. ### Trading and Market-Making Large investment banks maintain **trading desks** that buy and sell securities across equities, fixed income, currencies, and [commodities](/blog/what-are-the-commodities). Part of this activity is **market-making** — standing ready to buy or sell a security at quoted prices, earning the bid-ask spread on each transaction. The Volcker Rule, enacted after the 2008 financial crisis, restricted proprietary trading at banks with federally insured deposits. But the principle of using firm capital to facilitate client trading and maintain market liquidity remains central to how these firms operate. --- ## Mergers and Acquisitions: The Deal-Making Engine In mergers and acquisitions (M&A), investment banks act as advisors and dealmakers for buyers and sellers. They help clients identify acquisition targets or buyers, value the target business using rigorous financial models, structure deal terms, negotiate on behalf of their client, and arrange financing. Typically, one bank advises the buyer while a separate bank advises the seller. ![The seven-stage sequence an investment bank follows from mandate to deal

*The seven-stage sequence an investment bank follows from mandate to deal close.* The M&A process follows a consistent sequence: 1. **Strategy** — The client hires the bank and defines its objectives, whether that means acquiring a competitor, divesting a division, or finding a buyer for the whole company. 2. **Target identification** — The bank screens potential counterparties and runs preliminary financial analysis to determine fit. 3. **Valuation** — Analysts build **discounted cash flow (DCF) models**, comparable company analyses, and precedent transaction analyses to arrive at a defensible value range. 4. **Outreach and negotiation** — The bank contacts potential counterparties, manages information sharing under non-disclosure agreements, and negotiates key economic terms. 5. **Due diligence** — Both sides scrutinize financials, legal matters, intellectual property, and operational risks over four to eight weeks. 6. **Definitive agreement** — Lawyers draft the merger agreement; investment banks certify the deal is financially fair through a formal **fairness opinion** delivered to the board. 7. **Closing** — Regulatory approvals are obtained, acquisition financing closes, and ownership transfers. The 2022 proposed merger between Microsoft and Activision Blizzard — valued at $68.7 billion — illustrates the process. Goldman Sachs and Morgan Stanley advised Microsoft; Lazard advised Activision's board. Each bank earned tens of millions of dollars, contingent entirely on the deal reaching completion. --- ## Investment Banking vs. Commercial Banking: A Critical Distinction Commercial banks accept deposits from individuals and businesses and then use those funds to make loans. Investment banks help corporations and governments raise capital and execute large financial transactions — they do not accept retail deposits. The two were legally separated by the **Glass-Steagall Act** in 1933, then allowed to combine again after its repeal in 1999. Today, firms like JPMorgan Chase operate both types of businesses under one roof. ![Investment banks serve corporations and governments; commercial banks serve retail depositors — fundamentally different business models.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20800%20210%22%20width%3D%22800%22%20height%3D%22210%22%20role%3D%22img%22%3E%3Ctitle%3EComparison%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Ctext%20x%3D%22230%22%20y%3D%2257.5%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3ECommercial%20Bank%3C%2Ftext%3E%3Crect%20x%3D%22240%22%20y%3D%2225%22%20width%3D%22450%22%20height%3D%2255%22%20rx%3D%226%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22702%22%20y%3D%2257.5%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22%232563eb%22%3E700%3C%2Ftext%3E%3Ctext%20x%3D%22230%22%20y%3D%22152.5%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EInvestment%20Bank%3C%2Ftext%3E%3Crect%20x%3D%22240%22%20y%3D%22120%22%20width%3D%2284.85714285714286%22%20height%3D%2255%22%20rx%3D%226%22%20fill%3D%22%237c3aed%22%2F%3E%3Ctext%20x%3D%22336.8571428571429%22%20y%3D%22152.5%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22%237c3aed%22%3E132%3C%2Ftext%3E%3C%2Fsvg%3E) *Investment banks serve corporations and governments; commercial banks serve retail depositors — fundamentally different business models.* Most consumers interact with commercial banking daily — checking accounts, mortgages, auto loans. Investment banking is largely invisible to retail customers but shapes the economic environment they live in. Here's a direct comparison: | Feature | Commercial Bank | Investment Bank | |---|---|---| | Accepts retail deposits | Yes | No | | Makes consumer loans | Yes | Rarely | | Raises capital for corporations | No | Yes | | Advises on M&A | No | Yes | | Primary regulator | [FDIC](https://www.fdic.gov/), OCC | SEC, [FINRA](https://www.finra.org/) | | Examples | Wells Fargo, Bank of America | Goldman Sachs, Lazard | The original Glass-Steagall separation existed because lawmakers feared conflicts of interest. A bank that both holds customer deposits and underwrites risky securities could expose ordinary savers to institutional risks they never signed up for. The 2008 financial crisis rekindled that debate — several banks had combined commercial and investment operations that amplified system-wide instability and ultimately required a $700 billion taxpayer bailout under TARP. --- ## How Investment Banking Activity Affects Everyday Investors Investment banking activity directly shapes stock prices, market liquidity, and the investment products available to retail investors. When banks underwrite IPOs, they create new investment opportunities. When they advise on mergers, they create or destroy shareholder value in companies you may already own. When their trading desks quote prices across thousands of securities, they provide the liquidity that makes it possible for you to buy or sell shares in milliseconds. ### IPOs and Your Portfolio Every new IPO creates a fresh investment opportunity — but the playing field isn't level. The underwriting bank allocates shares to institutional investors first, during the roadshow pricing phase. Retail investors typically buy at the post-listing price, which sometimes reflects a 20–30% first-day pop. This structure matters. Historically, IPOs underperform the broader market over the three years following their debut, according to research by Jay Ritter at the University of Florida. Understanding the investment banking process behind an IPO helps you evaluate whether buying on day one — or waiting six to twelve months — makes more sense for your goals. ### Equity Research and Analyst Coverage Investment banks publish equity research covering thousands of publicly traded companies. When a senior Goldman Sachs analyst upgrades a stock from "neutral" to "buy," the market often reacts within minutes — sometimes moving the share price 3–7% in a single session. That research is valuable, but it isn't always conflict-free. Investment banks sometimes cover companies they have existing underwriting relationships with, creating potential pressure on analyst independence. After the dot-com bubble collapsed — and investigations revealed that analysts were privately dismissing stocks they publicly recommended — regulators required banks to erect strict **information barriers** between their research and investment banking divisions. --- ## Authoritative Sources For deeper background and primary-source data on this topic, the following authoritative sources are useful starting points: - [SEC — Securities and Exchange Commission](https://www.sec.gov/) - [Investor.gov](https://www.investor.gov/) - [SEC EDGAR](https://www.sec.gov/edgar) ## Conclusion Understanding what do investment bank do reveals the hidden infrastructure beneath every market headline. Here are the key takeaways: - **Investment banks are intermediaries**, not deposit-taking institutions — they connect capital-seekers with capital-providers. - **Underwriting and M&A advisory** are their two largest revenue sources, together generating tens of billions of dollars annually for the industry. - **They differ fundamentally from commercial banks** in their clients, their activities, and their regulatory framework — a distinction that matters when markets come under stress. - **Their work directly affects retail investors** through IPO pricing, analyst research, and the moment-to-moment liquidity they provide across financial markets. - **The industry spans bulge bracket giants** — Goldman Sachs, Morgan Stanley, JPMorgan — and specialized boutiques like Lazard and Evercore, each serving different niches within the same ecosystem. The next time you see a headline about a record-breaking merger or a high-profile IPO, you'll know exactly which institutions are pulling the strings — and what it means for the companies in your portfolio. As global capital markets grow more interconnected and complex, the institutions that move money between those seeking it and those supplying it will only become more influential.
