0.1 The Six Worlds of Finance
Finance is not one job but six different worlds. Corporate finance runs the money inside ordinary companies. Sell-side and banking sell services and advice. The buy-side invests money. Market infrastructure and operations keep trades moving. Advisory gives expert advice. Fintech builds new financial technology. The worlds differ most in how they earn: from their own capital, from fees, from the spread between prices, from commissions, or from holding money in transit, called float.
Why it matters: Knowing how a firm earns tells you what its people actually do all day.
Summary: Finance is six worlds: corporate finance, sell-side and banking, buy-side, market infrastructure and operations, advisory, and fintech. They differ most in how they earn: principal, fees, spread, commission or float.
- Corporate finance is a cost center; the other worlds sell financial services.
- Principal and spread businesses carry balance-sheet risk and build the heaviest control functions.
- Pay and cyclicality rise with proximity to revenue.
- Operations and infrastructure roles are the most numerous entry points.
“Working in finance” covers six different businesses that happen to share a vocabulary. They differ in who the client is, whose money is at risk and, above all, how the firm earns its revenue. The revenue model shapes the career: pay, cyclicality and which mistakes end careers. Parts A-D of this volume map the finance function under a CFO, mostly in the first world but also at banks, insurers and fund managers. Part E maps operations and control roles elsewhere.
Five revenue models recur. Principal revenue comes from risking the firm’s own capital (a trading book, a loan, an insurer’s investment portfolio). Fees are charged for advice, underwriting or administering assets, often in basis points of assets (one basis point is one hundredth of a percent). Spread is the gap between the price a firm buys at and sells at, or between what it pays for money and what it lends at. Commission is a charge per transaction executed for a client. Float is the income earned on money a firm holds before it has to pay it out: insurance premiums before claims, client cash before it settles.
| World | What it does | How it earns | Typical roles | How people enter | Stress point |
|---|---|---|---|---|---|
| 1. Corporate finance (the CFO world, Parts A-D) | Runs the money of a company that sells something else: books, cash, plans, tax, deals | Earns nothing directly; a cost center whose value is better decisions, cheaper capital and clean audits | Staff accountant, FP&A analyst, treasury analyst, tax analyst, internal auditor, corporate development associate | Accounting degree plus CPA (US) or CA (India); MBA for FP&A and corporate development; Big Four audit is the classic feeder | The close calendar and the forecast: deadlines are fixed and errors become public |
| 2. Sell-side and banking (investment banks, broker-dealers, commercial banks) | Sells services and products to issuers and investors: advice, underwriting, market-making, research, lending | Fees (advisory, underwriting), commission, spread (market-making, net interest margin on loans) and principal trading | Investment banking analyst (M&A, ECM, DCM), sales, trader, research analyst, structurer, credit analyst, relationship manager | Campus programs; in the US, FINRA’s SIE plus the license the job needs (Series 7, 79, 57 or 86/87), sponsored by the employer; CFA common in research | Hours and deal deadlines in banking; daily profit and loss in trading; revenue falls with market activity |
| 3. Buy-side (asset managers, hedge funds, PE and VC, pensions, sovereign funds, insurers’ investment arms) | Invests capital for owners or beneficiaries | Management fees as a percent of assets, performance fees or carried interest; pensions, sovereign funds and insurers earn investment returns (insurers on float) | Portfolio manager, buy-side analyst, investment associate, risk analyst, fund accountant, investor relations | Sell-side, consulting or Big Four valuation experience; CFA common, CAIA for alternatives, FRM for risk | Performance against a benchmark, investor redemptions and fund-raising |
| 4. Market infrastructure and operations | Exchanges, clearing houses (central counterparties), central securities depositories, custodians, payment systems, fund administrators and transfer agents, data and index providers | Fees per trade, per account or in basis points of assets held; data and index licenses; interest on client cash and margin (float) | Settlements analyst, reconciliations analyst, corporate actions analyst, fund administrator, client service manager, margin risk analyst | Graduate operations programs; few credentials required; India’s GCCs are a large entry route (see the India Lens) | Hard cutoffs: a trade, a payment or an income event either settles on time or does not; volume spikes with market stress |
| 5. Advisory and professional services | Audit, tax, consulting and deals advice, credit ratings, legal, actuarial consulting | Fees for time or by engagement; rating agencies mostly use the issuer-pay model (the issuer being rated pays) | Audit associate, tax consultant, transaction services analyst, ratings analyst, actuarial analyst, financial-regulation lawyer | CPA or CA for audit and tax; SOA or CAS exams for actuaries; law degree and bar admission for lawyers | Busy season, utilization targets and personal liability for an opinion that proves wrong |
| 6. Fintech | Payments, lending, neobanks, wealth tech, regtech | Transaction fees and a share of card interchange, lending spread, subscription software fees, fees on assets | Product manager, risk and fraud analyst, credit modeler, financial-crime compliance analyst, finance and treasury analyst, partnerships manager | Data and product skills (SQL, Python) matter more than credentials; compliance roles reward bank experience | Growth targets with thin margins; regulatory exposure often inherited through partner banks |
Two consequences follow. First, principal and spread businesses carry balance-sheet risk, so they build the heaviest control functions: banks and insurers have a Chief Risk Officer as a peer of the CFO (C.7: The Chief Risk Officer) and regulatory capital teams (C.15: The Head of Regulatory Capital & Reporting). Fee businesses carry less market risk but more operational and conduct risk. Second, pay tracks proximity to revenue. Roles that originate fees or take principal risk earn the most and are the most cyclical; roles that record and safeguard are steadier, more numerous and easier to enter.
The worlds overlap inside one group: a universal bank can run sell-side, lending, asset management and custody businesses side by side. Market infrastructure is regulated as systemically important: in the US, eight financial market utilities are designated under Title VIII of the Dodd-Frank Act, among them DTCC‘s Depository Trust Company (DTC), the central securities depository, and its National Securities Clearing Corporation (NSCC), the central counterparty for US equities.
Four questions on this chapter. Decide on your answer first, then click “Reveal Answer.”
1. A custodian charges 1.5 basis points a year on $400 billion of assets held. What is its annual safekeeping fee revenue?
- $6 million
- $40 million
- $60 million
- $600 million
Reveal Answer
Answer: C. $400 billion × 1.5 ÷ 10,000 = $60 million. One basis point is one hundredth of a percent.
2. Which revenue model describes an insurer earning investment income on premiums before claims are paid?
- Commission
- Advisory fees
- Spread
- Float
Reveal Answer
Answer: D. Float is income earned on money held before it must be paid out.
3. Which world is a cost center rather than a seller of financial services?
- Corporate finance under a company’s CFO
- A rating agency’s analysts
- A broker-dealer’s sales and trading
- A custodian’s asset servicing
Reveal Answer
Answer: A. Corporate finance earns nothing directly; it serves a company that sells something else.
4. A graduate wants a US sell-side trading role. What licensing path applies?
- The CAIA Level I exam plus two years’ experience, taken before joining a firm
- The SIE plus a qualification exam, taken while associated with a member firm
- A state CPA license before trading, since that exam governs all trading roles
- The CFA Level I exam passed before any job offer, since firms do not sponsor it
Reveal Answer
Answer: B. FINRA requires the SIE and a qualification exam such as the Series 57; the qualification exam needs firm association.
0.2 Front, Middle and Back Office: The Grid
Think of a restaurant. The front office is the dining room and kitchen, which earn the money and take the risks. The middle office is the manager who checks and values everything independently. The back office is the accounts team that settles the bills and keeps the records. In a finance firm, control functions and corporate support sit across all three, like the security and the head office of a whole chain.
Why it matters: The grid shows who makes the money, who checks it and who records it.
Summary: The front office earns revenue and takes risk, the middle office checks and values it independently, and the back office settles and records it. Control functions and corporate support sit across all three.
- The person who earns a profit must not record, value or settle it.
- Barings collapsed in 1995 after a trader also ran his own back office.
- In market infrastructure, settlement and custody are the product.
- Operating companies and advisory firms do not use the grid in this form.
Inside any firm that trades, lends or holds assets for others, work is split by what it does to a transaction. The front office wins the business and takes the risk: it faces clients, prices deals and earns the revenue. The middle office measures and checks that risk independently of the people paid on it: it captures trades correctly, values positions, calculates profit and loss, and monitors limits and margin. The back office makes the transaction real and records it: confirmation, settlement, reconciliation, corporate actions, client-asset records and the accounting entries. Two further rows sit across all three. Control functions (risk, compliance, internal audit) set and test the rules; in the three lines model, the business is the first line, risk and compliance the second, and internal audit the third (C.5: The Head of Internal Audit). Corporate support (finance, tax, treasury, investor relations) runs the firm itself, the world mapped in Parts A-D.
The rule behind the separation: the person who earns a profit must not record, value or settle it. A trader who can also book, confirm and reconcile their own trades can hide a loss until it is too large to survive.
Nick Leeson traded futures for Barings in Singapore and also ran the back office that processed his trades, hiding losses in a concealed account numbered 88888. When Barings collapsed on February 26, 1995, the cumulative loss was £827 million, more than the bank could absorb; ING took the group over. The UK Chancellor’s statement on the Board of Banking Supervision report records that Barings’ internal auditors had recommended in 1994 that Leeson, as a trader, should not run the back office, and that the recommendation was not implemented. The report concluded that the position “could not have been established if there had been an effective system of management, financial and operating controls”. The grid’s segregation rules answer failures of this kind.
| Row | Sell-side and banking | Buy-side | Market infrastructure | Fintech |
|---|---|---|---|---|
| Front office (earns, takes risk) | M&A and capital-markets bankers, sales, traders, research, structurers, lenders and relationship managers | Portfolio managers, analysts, buy-side traders, capital raising and investor relations | Sales and client relationship managers, product managers for clearing, custody or data | Product managers, partnerships and merchant sales, credit underwriting strategy |
| Middle office (checks, measures) | Trade support, product control, collateral and margin, independent price verification | Investment operations, performance measurement, portfolio valuation, trade support | Margin and risk calculation at central counterparties, client onboarding and data quality | Fraud and transaction monitoring, credit risk analytics |
| Back office (settles, records) | Settlements, reconciliations, corporate actions, client-asset records, regulatory transaction reporting | Fund accounting, settlements and reconciliations (often outsourced to a fund administrator and custodian) | Settlement, safekeeping, asset servicing, transfer agency, fund administration (this is their front line of service) | Payment operations, reconciliations, disputes and chargebacks |
| Control functions | Chief Risk Officer, market and credit risk, compliance, internal audit | Chief Compliance Officer, investment risk, valuation committee | Risk management, compliance, internal audit, regulatory reporting | Financial-crime compliance, risk, audit (often built up to meet partner-bank demands) |
| Corporate support | CFO, financial control, treasury and ALM, regulatory capital, tax | CFO of the management company, fund and firm accounting, tax | CFO, controller, treasury | CFO, controller, FP&A, treasury (safeguarding of customer funds) |
Three reading rules make the grid useful. One: the labels describe functions, not buildings. A small fund may have one operations person doing both, checked by its administrator and auditor. Two: in market infrastructure the “back-office” activities are the product, so settlement and custody staff are client-facing. Three: operating companies and advisory firms do not use the grid in this form. A manufacturer’s finance team is corporate support throughout, and an audit firm’s engagement teams are its front office. Because the middle office sees a desk’s whole profit and loss, product control (E.7: Product Control) is a common route into bank finance and risk leadership.
Four questions on this chapter. Decide on your answer first, then click “Reveal Answer.”
1. A desk marks a bond position at $10.4 million; the middle office’s independent price is $9.9 million. What does the middle office report?
- A $1.0 million overstatement to resolve
- A $0.5 million understatement to resolve
- A $0.5 million overstatement to resolve
- No issue, as the desk’s mark governs
Reveal Answer
Answer: C. $10.4 million − $9.9 million = $0.5 million; the independent price, not the desk’s, is the control.
2. What was the central control failure at Barings in 1995?
- A trader also ran the back office that processed his trades
- The auditors were not allowed into the Singapore office
- The bank had no futures exchange membership in Singapore
- Settlement was moved to an outside custodian in London
Reveal Answer
Answer: A. Leeson ran both trading and its back office; a 1994 internal audit recommendation to separate them was not implemented.
3. In the three lines model, where do risk and compliance sit?
- The first line
- The second line
- The third line
- Outside the model
Reveal Answer
Answer: B. The business is the first line, risk and compliance the second, internal audit the third.
4. Why are settlement staff at a custodian client-facing?
- Regulators require settlement staff to sell custody services
- Custodians earn mainly from trading commission on client orders
- Custodians have no middle office, so staff must serve clients
- In market infrastructure, back-office services are the product sold
Reveal Answer
Answer: D. Settlement, safekeeping and asset servicing are what infrastructure firms sell.
0.3 Where Every Role in This Volume Sits
Every role in this volume has a home world and a place on the grid, from the CFO, who sits in corporate support, to settlements, which sits in the back office. The same job title can mean quite different work in different worlds. So before you read about a role, find out which world it lives in.
Why it matters: A title tells you much less than the world around it.
Summary: Every role in this volume has a home world and a row of the grid, from the CFO (corporate support) to settlements (back office). The same title can mean different jobs in different worlds.
- Part C roles sit mostly in corporate support and control functions.
- Part E roles are the middle and back office of banks, funds and infrastructure.
- Controller, risk and treasury change meaning between a company, a bank and a fund.
- Ask whose money, which revenue model and which row before judging a title.
Each role in this volume has a home world and a row of the grid; the same role changes shape when it moves between worlds. The first world named is the most common home.
| Role | Home world(s) | Row of the grid | Covered in |

| Relationship Management | Banking, private wealth, infrastructure (custody clients) | Front office | E.11 |
Titles travel badly between worlds; the same word can name very different work:
| Title | At an operating company | At a bank or broker-dealer | At a fund manager |
|---|---|---|---|
| Controller | Owns the books and the close (C.1: The Controller) | Financial controller for a legal entity, or product controller explaining a trading desk’s daily P&L (E.7: Product Control) | Fund controller overseeing fund accounting and the NAV, often through an administrator (C.12: The Head of Fund Accounting) |
| Risk | Enterprise risk register, insurance, business continuity (C.7: The Chief Risk Officer) | Market, credit, liquidity and operational risk against regulatory capital (C.7: The Chief Risk Officer, C.15: The Head of Regulatory Capital & Reporting) | Portfolio risk: exposure, leverage and liquidity of each fund against its mandate |
| Treasury | Cash, funding, hedging (C.2: The Treasurer) | Funding and the interest-rate gap of the whole balance sheet (E.9: Treasury and Asset-Liability Management (ALM)) | Financing, collateral and cash for leveraged funds (E.5: Collateral and Margin) |
| Analyst | FP&A or accounting analyst | Junior banker building models, or a research analyst publishing on stocks | Investment analyst recommending positions |
| Operations | Shared-service processing: payables, receivables, payroll | Settlements, reconciliations, corporate actions (Part E) | Investment operations, often overseeing outsourced administrators |
A practical test for any job description: ask whose money (the company’s, clients’ or the firm’s own), what revenue model (Section 0.1: The Six Worlds of Finance), and which row (Section 0.2: Front, Middle and Back Office: The Grid). The answers predict hours, pay and exits better than the title. Part H maps the common moves between worlds.
The Securities and Exchange Board of India (SEBI), a statutory body under the SEBI Act, 1992, regulates the sell-side, the buy-side (mutual funds, portfolio managers, AIFs) and market infrastructure. The Reserve Bank of India (RBI) regulates banks under the Banking Regulation Act, 1949 and payment systems under the Payment and Settlement Systems Act, 2007. IRDAI regulates insurers. SEBI calls exchanges, clearing corporations and depositories market infrastructure institutions (MIIs): the exchanges include NSE and BSE, and the two depositories are NSDL and CDSL. Indian equities moved fully to T+1 settlement on January 27, 2023, more than a year before the US, and SEBI added an optional T+0 cycle for a limited set of stocks in March 2024.
The larger employer of Indian finance graduates is the global capability center (GCC), also called a global business services (GBS) center or captive: a multinational’s own unit in India. India hosts more than 1,700 GCCs employing over 19 lakh people. For global banks, asset managers and custodians, the GCCs in Bengaluru, Hyderabad, Pune, Chennai and Gurugram typically run back- and middle-office work on the grid in Section 0.2: Front, Middle and Back Office: The Grid: settlements, reconciliations, corporate actions, fund accounting and NAV production, trade support, product control reporting and regulatory reporting. For corporates they run record-to-report, payables and receivables. The front office, client sign-off and accountable control owners typically stay onshore. Indian entry credentials are the CA (Institute of Chartered Accountants of India), CMA (India) and CS for corporate finance and compliance roles, and a commerce degree or MBA for operations roles.
Four questions on this chapter. Decide on your answer first, then click “Reveal Answer.”
1. A bank advertises a controller role explaining a trading desk’s daily P&L. Which row and section fit?
- Front office, relationship management (E.11: Relationship Management)
- Corporate support, corporate controller (C.1: The Controller)
- Middle office, product control (E.7: Product Control)
- Back office, settlements (E.1: Settlements)
Reveal Answer
Answer: C. Explaining a desk’s daily P&L is product control, a middle-office finance role.
2. Where does fund accounting (C.12: The Head of Fund Accounting) sit on the grid?
- Back office, often outsourced to a fund administrator
- Control functions, as the independent third line of defense
- Corporate support of an operating company’s finance team
- Front office, alongside the portfolio managers who trade
Reveal Answer
Answer: A. Fund accounting records positions and strikes the NAV, often at an administrator.
3. How does bank treasury differ from a manufacturer’s treasury?
- It reports to the chief revenue officer and sets customer pricing
- It values private holdings for investors and prepares the fund accounts
- It only pays suppliers and collects receivables for the bank’s own operations
- It manages funding and the interest-rate gap of the whole balance sheet
Reveal Answer
Answer: D. At a bank the balance sheet is the product, so treasury and ALM (E.9: Treasury and Asset-Liability Management (ALM)) manage it.
4. Which three questions best decode an unfamiliar job title?
- Which exam, which salary, which sector index to follow
- Whose money, which revenue model, which row of the grid
- Which degree, which title, which manager the role reports to
- Which city, which team size, which software the team runs
Reveal Answer
Answer: B. These predict hours, pay tier and exit routes better than the title.
- CFA Institute: CFA Program — Three levels; 4,000 hours over 36 months
- Federal Reserve: Designated Financial Market Utilities — Eight designated FMUs; DTC as CSD, NSCC as CCP
- FINRA: Qualification Exams — Series 7, 57, 79, 86/87 names

- SEC: Staff Report on NRSROs (April 2026) — Issuer-pay as the primary NRSRO business model
- SEBI (SEBI)
- RBI: legal framework
- SEC T+1 release
