Investment banking vs corporate finance: what is the difference?

Corporate finance, in the sense a student usually means, is the finance job inside a company: the people under the chief financial officer who decide what to invest in, how to pay for it and how to manage the cash. Investment banking is the outside firm that company hires when it wants to buy, sell or raise money. One is the client; the other is the adviser. The confusion comes from the phrase itself, which banks also use for part of their own advisory business.

Corporate finance inside a company

A corporate finance textbook describes the job by its three tasks: making investment decisions, which projects and purchases are good uses of the money shareholders have put in; making financing decisions, whether to pay for them by selling shares or by borrowing; and managing the firm’s cash flows[1Source 1Jonathan Berk and Peter DeMarzo, Corporate Finance, 5th ed. (Pearson, 2019), ch. 1, “The Financial Manager”, p. 39.]. In a large firm the work sits under a top officer, the chief financial officer, to whom a treasurer and a controller report: the treasurer handles cash flows, capital spending decisions and financial plans, and the controller handles accounting, tax, cost accounting and information systems[2Source 2Stephen A. Ross, Randolph W. Westerfield, Jeffrey Jaffe and Bradford D. Jordan, Corporate Finance, 12th ed. (McGraw-Hill, 2018), ch. 1, “The Financial Manager”, pp. 3–4.]. The organisation chart runs from the board of directors through the chief executive to the chief financial officer and those two[1Source 1Jonathan Berk and Peter DeMarzo, Corporate Finance, 5th ed. (Pearson, 2019), ch. 1, “The Financial Manager”, p. 39.].

That is the job many finance graduates who do not go to a bank will do, at a company, a hospital or a government body: budgeting, planning, reporting, treasury, and the analysis behind decisions to build, buy or borrow.

Where the bankers come in

A bank’s client coverage bankers work to become experts in an industry and in the strategic and financing objectives of the companies they cover; they help chief executives and finance chiefs with questions of shareholder value and risk, which sometimes leads to a merger or a sale, and with capital structure, which often leads to an issue of equity or debt[3Source 3David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 1, “Client Coverage Bankers”.]. To do that they build relationships with two groups inside the company. Corporate development, usually reporting to the chief financial officer, identifies, analyses and executes strategic transactions such as mergers, acquisitions and divestitures. Treasury, also under the chief financial officer, keeps the cash balances, works toward the right capital structure, manages the balance sheet’s risks and deals with the rating agencies[3Source 3David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 1, “Client Coverage Bankers”.]. In a transaction, the company’s side is senior management, who set strategy and choose advisers; corporate development, who bring the bankers’ best ideas to management and work on execution; the board, which recommends or rejects; and the business unit heads, lawyers, investor relations and accountants who take part[4Source 4David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 4, “Other Merger and Acquisition Participants”.].

The other meaning of the phrase

At a bank, “corporate finance” also names part of its own advisory business. A guide to the industry describes a bank as split into a banking side inside the Chinese wall, whose bankers include those working on mergers and those “dedicated to corporate finance or the raising of capital”, and a markets side outside it[5Source 5Philippe Espinasse, IPO: A Global Guide, 3rd ed. (Hong Kong University Press, 2018), §1.5.1, “The banking side”, and §1.5.2, “The markets side”.]. An ethnography of the industry likewise uses corporate finance and M&A together to mean “investment banking proper”[6Source 6Karen Ho, Liquidated: An Ethnography of Wall Street (Duke University Press, 2009), introduction, pp. 5–6.]. When a bank says corporate finance, then, it usually means work in its investment banking division; when a company says it, it means the treasury, planning and development functions above.

Which to choose

The trade-off is the usual one between adviser and principal. A banker sees many companies and many deals in a few years and works the long hours that go with that[7Source 7David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 10, “Investment Banking”, p. 222.]; someone in a company’s finance function sees one business from the inside and owns the decisions rather than the advice. Many people do both, moving from a bank into a corporate development or treasury role, which one textbook lists, as “other companies”, among the destinations of departing analysts, alongside business and law school, private equity and hedge funds[8Source 8K. Thomas Liaw, The Business of Investment Banking: A Comprehensive Overview, 3rd ed. (Wiley, 2011), “Investment Banking Financial Analysts”, pp. 52–53.].

Frequently asked questions

Is corporate finance the same as investment banking?

No, though the phrase is used both ways. Inside a company, corporate finance is the CFO’s function of investing, financing and cash management; at a bank the same phrase names one of the advisory departments that serve those companies[1Source 1Jonathan Berk and Peter DeMarzo, Corporate Finance, 5th ed. (Pearson, 2019), ch. 1, “The Financial Manager”, p. 39.][5Source 5Philippe Espinasse, IPO: A Global Guide, 3rd ed. (Hong Kong University Press, 2018), §1.5.1, “The banking side”, and §1.5.2, “The markets side”.][6Source 6Karen Ho, Liquidated: An Ethnography of Wall Street (Duke University Press, 2009), introduction, pp. 5–6.].

Who does an investment banker work with inside a company?

The chief executive and chief financial officer, and below them corporate development, which handles strategic transactions, and treasury, which manages cash, capital structure and the rating agencies[3Source 3David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 1, “Client Coverage Bankers”.].

Is corporate finance a good path into investment banking?

It can be; one textbook lists professionals from other industries among the occasional hires into associate and even more senior roles, though most senior bankers are promoted from within or hired from other banks[7Source 7David P. Stowell, Investment Banks, Hedge Funds, and Private Equity, 3rd ed. (Academic Press, 2017), ch. 10, “Investment Banking”, p. 222.].
