A borrower's customers have joined a supply-chain finance programme run by their banks. Its debtor days fell from 70 to 30 in one quarter. The relationship manager says it has 'fixed its collections'.

Ground floor · The hall
Transaction Banker
Sells and structures the plumbing a business runs on — accounts, payments, collections, liquidity and trade finance.
BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED
// 01 — WHAT A TRANSACTION BANKER DOES
It is the least glamorous revenue in the bank and among the stickiest: once a company's payroll, receivables and supplier payments run through your systems, it does not move for a basis point. Trade finance sits here too, which puts letters of credit, guarantees and receivables funding in the same conversation as cash management.
// 02 — WHO ARRIVES HERE
Graduate streams, internal moves from business banking or operations, and specialists who come with a trade or payments background.
// 03 — WHAT THE INTERVIEW ASKS
These are the shapes the round takes, not a question bank — banks phrase them differently and the wording is never the point.
- 01Walk me through a client's cash cycle and where we could sit in it.
- 02Why would a company pay for a letter of credit rather than trade on open account?
- 03What is the difference between a client's liquidity problem and a funding problem?
- 04How would you find the transaction banking opportunity in a lending client?
- 05A payment file fails on a Friday afternoon. What is your first move?
- 06Where does this business actually make money for the bank?
What the panel is listening for. Whether you can see a company as a set of flows rather than a set of products, and whether you understand that operational reliability is the product.
Practise the round in the front-line quiz: one of its five questions is this seat's own, and every answer has the senior interviewer's read.
Take the quiz →// 04 — WHY CREDIT PAYS IN THIS SEAT
Cash flows through the bank's own systems are the earliest, truest warning a lender gets — a receivables pattern breaking is visible here weeks before it reaches a set of accounts.
Payments and collections show a business's working capital moving in real time — the same cycle a credit analyst reconstructs from year-end accounts months later. Knowing what the pattern means when it changes is the read this site practises.

// 05 — A DAY IN THE SEAT
- 08:30Overnight exceptions: a payment file that failed, a collection that did not land, a client who noticed before you did.
- 09:30A client's cash cycle mapped with the relationship manager: where money comes in, waits, and goes out — and where the bank could sit in it.
- 11:00A trade query: the exporter's letter of credit, the documents it demands, and whether the client's paperwork will comply.
- 13:00A pitch for a collections solution to a business whose receivables arrive by cheque and by chance.
- 14:30A liquidity structure priced: the balances a client keeps, what they are worth to the bank, and what to pay for them.
- 16:00The pipeline: which lending clients do not yet run their flows through the bank, and why.
The shape of a day, not a rota — banks and books differ. A relationship manager's day is on what a commercial banker does.
// 06 — WHAT THE FIRST YEAR TESTS
- Whether you can see a company as a set of flows rather than a set of products.
- Whether you understand that reliability is the product, and treat a failed file as the day's first priority.
- Whether you can find the transaction banking opportunity inside a lending relationship.
- Whether you know what a letter of credit, a guarantee and a receivables line each do, and which one a client actually needs.
- Whether operations trusts you, because everything you sell they have to run.
// 07 — WHAT YOU SEE FROM HERE
The client's own payments and collections as they happen, rather than the year-end snapshot a lender reads — and, often before anyone else in the bank, the first break in a pattern that has held for years. The seat also sees where a bank's stickiest revenue really comes from, which is rarely the loan.
// 08 — THE FILES TO PRACTISE ON
- ISSUE 02Aoraki Trade ExportsAn exporter, a documentary collection and a multi-currency line — trade and cash management in one file.
- ISSUE 04Highview IndustriesA working capital cycle that behaves — the flows this seat would want to run.
- ISSUE 06Kowhai Retail GroupA seasonal business whose cash arrives in one quarter: collections, the season and the clean-down.
// 09 — WHERE THE SEAT LEADS
Senior transaction banker, head of transaction banking, or the trade finance specialist seats; some move into product, operations leadership or corporate coverage, carrying the flows view with them. Its revenue holds against price competition, though when a client moves its lending, the flows often follow.
