The industry map
The atlas is organised by subject: instruments that trade on one side, transactions that are negotiated on the other. That is the right way to arrange the material and it says nothing about the people who do this for a living. This page is the other axis — the seat rather than the subject — and it exists because a reader arriving with I have an interview at a hedge fund or what does a structurer actually do found the material here and no door into it.
Three levels: which side of the price somebody is on, which group the seat belongs to, and the seat itself. Everything below links back into the pages that explain the instruments — nothing here explains an instrument a second time.
What this is not. It is not careers advice and it does not describe any named employer. Firms genuinely disagree about where the lines fall: structuring sits in markets at one bank and in the investment bank at another, private credit is an asset-management product in one house and a private-markets fund in the next. Where that matters it is said rather than smoothed over. All of it is information and education only — see the disclaimer.
In short
53 seats, in six groups, on two sides of one question: who is quoting, and who is choosing. 46 of them have a page here and the other 7 are the transaction desks, which already do.
Sell-SideQuotes the price and stands behind it.
Banks and brokers. They make a market, arrange a transaction or underwrite an issue — and are paid for the service and for carrying the risk in between. The seat is judged on the flow it wins and the risk it does not get stuck with.
Investment Banking
Advising on and arranging the things a company does once rather than daily: being bought, listing, borrowing at size, restructuring what it already owes.
Markets
Quoting, holding and hedging instruments for clients who want to buy or sell them — and building the ones that do not exist off the shelf.
Every markets seat is described by a pair: what it does and what it does it in. The eleven asset classes are the second half — the same eleven the atlas is built on, because there is only one shelf on this site.
The eleven: Cash Equities Equity Derivatives Fixed Income Rates Derivatives Credit Derivatives Foreign Exchange FX Derivatives Money Markets Commodities Alternatives & Private Markets Digital Assets
Buy-SideDecides whether to take it.
The institutions that own the money — funds, insurers, pensions, endowments and the households behind them. They choose what to hold and for how long, and are judged on what the holding did, against something.
Asset Management
Running portfolios against a stated objective for clients who are usually institutions. Mostly liquid instruments, mostly measured against an index or a liability.
Private Markets
Buying companies, funding new ones and lending to them directly — with capital committed for years and a value that is an opinion until somebody buys it.
Hedge Funds & Alternatives
Funds that may go short, use leverage and hold instruments an index does not contain — organised by the idea they are expressing rather than by the asset class it lives in.
Wealth Management
Advising individuals and families rather than institutions, where tax, succession, a concentrated holding and somebody's own nerve are part of the problem rather than noise around it.
Insurance & Pensions
The largest asset owners there are, and the only ones whose liabilities are written before the assets are bought: a claim that may arrive, or a pension that certainly will.
BankingTakes the deposit, makes the loan, moves the money.
The oldest business in finance and the largest by headcount: holding other people's money and lending it to somebody else for longer than it was deposited. Nothing here trades on a screen, and the mismatch between the two sides is the business rather than a flaw in it.
Retail & Business Banking
Current accounts, savings, cards, mortgages and small business credit. The part of finance almost everybody uses and almost nobody on a trading floor can describe.
Corporate & Transaction Banking
Lending to companies, running the accounts their cash moves through, financing what they ship, and managing the bank's own balance sheet behind all of it.
The customerThe company every seat above is selling to.
Not a firm in finance at all: an ordinary company's own finance function, which is the customer for most of what the sides above sell. It sat under the system for one release, which was wrong in a way worth naming — a treasurer sets no rules and runs no plumbing; they are the one being quoted a price.
The Client Side
A company's own finance function: the treasurer who actually signs the hedge, and the team that explains the results to the investors who own the shares.
The system around itSets the rules, runs the plumbing, keeps the score.
Nobody's counterparty and everybody's constraint: central banks and supervisors, the exchanges and clearing houses a trade passes through, and the firms that publish a rating or an index everybody else quotes.
Central Banks & Supervisors
The institutions that issue the currency, set the policy rate, lend when nobody else will, and decide what a bank is allowed to hold and how much capital it must hold against it.
Market Infrastructure
Exchanges, clearing houses, custodians and the firms that publish a rating, an index or a price. None of them takes the other side, and everything passes through them.
In every firm aboveNot a kind of firm — a kind of seat.
The seats that take no position and without which no position can be taken: whoever says no, whoever proves the number, whoever makes it settle, and whoever writes the system it settles in. A bank has them, so does a fund, so does an exchange — which is why they are a band of their own rather than a line under one of the others. They are judged on what did not happen, the hardest thing in finance to be paid for.
Risk, Compliance & Audit
The second and third lines: measuring what the firm could lose, deciding what it is not permitted to do, and checking afterwards that the first two actually happened.
Operations & Technology
Settling it, reconciling it, proving the profit and loss is real, and writing the systems all of that runs on. Invisible from a price screen and unavoidable from every other seat.
How to use it
- If you know the seat, open its page: what it does, what a day looks like, what it is measured on, how it goes wrong, and the concepts underneath it.
- If you know the subject, start from the atlas or the transactions instead, and let the page tell you which seats touch it.
- If you have an interview, the prep guides are arranged around the deadline rather than around the subject, and every desk and asset class carries the questions an interview asks about it.
