// FOR CANDIDATES AND BANKERSA SCORECARD, OR A PERSON WHO READ THE FILE

Commercial Banking vs Retail Banking

One serves people and decides by model. The other serves businesses and decides by someone who read the file. The difference is the whole shape of the job.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED

// THE SHORT ANSWER

Retail banking serves individuals — accounts, cards, mortgages — and decides most credit by scorecard, with a person seeing only the exceptions. Commercial banking serves businesses, and each facility is decided by people who read that business's numbers, industry and owners and write a recommendation. One is a product business run on volume and models; the other is a judgment business run on files. The careers follow: retail has more seats and a faster start, commercial a longer apprenticeship and a craft that compounds. The usual crossing runs through business banking, and is made the day you can read three statements in order.

BASIS  Practitioner judgment from sixteen years in commercial banking, set out in How Bankers Think (Highbank Press, 2026). Every borrower on this site is a composite constructed for teaching, not a client. The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

// PRACTISE THE ROUND

Five questions commercial banking panels genuinely ask, with the senior interviewer's read on every answer — a quiz that tests judgment, not recall.

// 01 — TWO BANKS UNDER ONE ROOF

Walk into any large bank and you are standing in two businesses that share a brand, a balance sheet and a lift. Retail banking is the one you can see: the branches, the app, the cards, the home loans, the millions of customers who are each a small part of the whole. Commercial banking is upstairs and out of sight — a few thousand business customers, each a large part of the whole, each with a file, a relationship manager and a credit analyst who has read their last three years. What Jobs Banks Hire For maps the whole building; this page is the comparison between its two lending floors.

// 02 — HOW THE DECISION IS MADE

This is the real difference, and everything else follows from it. A retail credit decision is made by a scorecard. The bank has seen millions of borrowers like this one, knows how borrowers with this income, this deposit, this history and this postcode behaved, and scores the application against them. A person sees it only when the score lands in a band that needs a look, or when a rule fires. This is not laziness; it is the right way to decide a million small, similar things, and the model is usually better at it than any one banker would be.

A commercial credit decision cannot be made that way, because no two businesses are similar enough. A joinery firm and a dairy farm and a listed retailer share almost nothing a model could score; what they share is that someone has to read them. So a credit analyst reads the three statements in order, asks the Three Questions, writes a paper with the answer in its first sentence, and a person with delegated authority signs it or does not. The unit of retail is a product sold to many; the unit of commercial is a file read once.

Retail · millions of customers · standard products · scorecard decides, people handle exceptions · risk managed as a portfolio of small, similar loans
Commercial · thousands of customers · structured facilities · a person decides, a model informs · risk managed one file at a time, then as a book

// 03 — WHAT THE CUSTOMER EXPERIENCES

A retail customer meets the bank through a product: the account, the card, the mortgage, priced from a rate card and serviced through a channel. A commercial customer meets the bank through a person — the relationship manager — who knows the business, brings its requests to credit, and is measured on whether the relationship grows and holds. The facilities are structured rather than chosen from a menu: a working capital line sized to a cash conversion cycle, a term loan shaped to an asset's life, covenants set to the business's own numbers. Pricing is negotiated inside a margin the desk works out from the risk grade, and the customer is reviewed every year by someone who reads the accounts again. The borrower's side of that relationship is what How Banks Read You describes.

// 04 — THE CAREERS

Retail has more seats and a faster start. The personal banker in a branch is the bank's biggest single job, and the ladder from it runs through team leadership, branch and regional management, or sideways into product, digital and operations, where the scale of retail makes the interesting problems. What retail does not build, because the model does it, is the skill of reading a business.

Commercial has fewer seats and a longer apprenticeship, and the apprenticeship is the point. The career path runs analyst, lender, then the fork between holding a portfolio and holding credit authority; the senior seats pay more than their retail equivalents, and the craft travels — to corporate banking, to credit funds, to advisory, to running a business yourself. The most common route in from retail is through business banking, the small-business segment where a personal banker first sees a company's accounts; the crossing is made the day you can read three statements in order, and the interview is built to test exactly that.

// 05 — WHERE THEY OVERLAP

Three places. Business banking, the segment between them, where small facilities are partly scored and partly read and a banker in a branch does both. Property, where a home loan and a business loan can be secured on the same building and the only question is whether a person or a business is repaying it. And the owner: a commercial customer's personal guarantee reaches into their retail life, and a commercial desk that reads the owner's own position is doing, by hand, what the retail scorecard does by model.

// 06 — WHICH ONE FOR YOU

Choose retail if you like people, process and scale, and want a career whose interesting problems are about serving many well. Choose commercial if you want to read a business, form a view and be answerable for it — if the question that holds you is whether this company, with these people, through this cycle, pays the money back. The week on the desk shows what the second one looks like on a Tuesday. The comparison with the floor above commercial is here, and with investment banking here.

// QUESTIONS PEOPLE ASK

What is the difference between retail banking and commercial banking?
The customer and the way the decision is made. Retail banking serves individuals — accounts, cards, mortgages, personal loans — and decides most credit by scorecard: the application is scored against the behaviour of millions of similar borrowers, and a person only sees the exceptions. Commercial banking serves businesses, and each facility is decided by people who read that business's numbers, its industry and its owners, and write a recommendation. One is a product business run on volume and models; the other is a judgment business run on files.
Is a mortgage retail or commercial banking?
A home loan to a person is retail, even a large one, because the decision rests on the borrower's income and the property, and it is scored. A loan to a business secured on property — an owner buying the premises, a developer building townhouses, an investor with a rent roll — is commercial, because the repayment comes from a business and the decision needs someone to read it. The same building can be either, depending on who is borrowing and where the money to repay comes from.
Is business banking the same as commercial banking?
Banks use the words to mark the small end of the same thing. Business banking, or small business banking, is the segment just above retail — sole traders and small companies whose facilities are small enough to be partly scored and partly read, often by a business banker in a branch. Commercial banking is the next segment up, where every facility is read and written up by an analyst, with a relationship manager who carries a portfolio. The line between them moves by bank, and the credit skills are the same in kind.
Which is better to work in, retail or commercial banking?
Retail banking has more seats, faster entry, and a clearer product-and-service ladder — branch, then team leader, then region, or across into product, digital or operations. Commercial banking has fewer seats, a longer apprenticeship, and a craft that compounds: reading businesses. The commercial seats pay more once you hold a portfolio or credit authority, and the skill travels — to corporate banking, to credit funds, to advisory. If you like people and process, retail; if you like reading a business and being answerable for a call, commercial.
Can I move from retail banking to commercial banking?
Yes, and it is one of the most common routes in. The usual bridge is business banking — the small-business segment inside or beside the branch network — where a personal banker starts seeing company accounts, then a credit analyst seat once they can read three statements in order. What the commercial side is testing at that point is not product knowledge but reading: the interview will hand you a business and want a view. The interview pages on this site are built for exactly that crossing.
