What Does a Commercial Banker Do?

A commercial banker reads operating businesses from their numbers and decides what a bank can safely lend them, in what form, and on what conditions — then lives with the decision for as long as the relationship runs. Everything else in the job is a variation on that sentence.

The work is done from two chairs. The relationship side owns the client: winning the business, growing the book, sitting across the table when things are good and when they are not. The credit side owns the judgment: reading files, writing the papers, holding the line on structure. In most banks these are separate seats that argue with each other on purpose — the argument is the quality control. A banker who has only ever sat in one chair is half-trained, and the senior people in this industry can read a file and hold a room in the same afternoon.

A composite week, drawn from practice rather than a position description. A facility request comes in from a growing distributor: two hours with three years of financials, testing whether the growth is real, whether profit is converting to cash, and whether the request matches what the cash conversion cycle says the business actually absorbs. A credit paper drafted and argued over: the recommendation up front, the risks named, a covenant package that would actually catch trouble rather than decorate the letter. An annual review that turns into something else, because debtor days have drifted twenty days and the last two management reports arrived late — and lateness is itself a signal.

Then the table work: a site visit where the warehouse contradicts the stock number, a difficult conversation carrying credit's conditions back to an owner who wanted a simple yes, an hour with a long-standing client whose succession plan is quietly a new lending decision. None of it is glamorous. All of it compounds: the same borrowers, read again and again, until pattern recognition becomes the job's real asset.

Not vocabulary, and not effort. A junior banker and a senior banker looking at the same file see different things: the junior sees the numbers, the senior sees what the numbers are doing — which ones move together, which movement is benign at this size and dangerous at that one, what is missing from the file that should be there. That gap closes one way: repetitions. Files called, outcomes observed, reads corrected against what actually happened.

That is the premise this whole site is built on — judgment is built from cases, not courses — and it is why every case drill here asks for your call before showing the senior banker's read of the same file. The gap between your read and the senior's, examined honestly, is the fastest teacher the profession has.

Three common confusions, handled without condescension. It is not investment banking: no deal fever, no pitch books, a different skill set and a different clock — the full comparison is at commercial banking vs investment banking. It is not retail banking: the clients are businesses, the products are structured rather than standardised, and the decisions are argued rather than scored. And it is not investing: a commercial banker's upside is capped at getting repaid, which is precisely why the discipline runs on downside judgment — the second way out, the covenant that catches, the request declined as framed.

Four, in rough order of acquisition. Reading financials the way a desk reads them — for cash and direction, not presentation. Structuring — matching a facility's size, shape and tenor to a real cash cycle instead of to the request. Watching — holding a baseline per borrower and noticing departures, including the signal of silence, the report that stops arriving. And carrying decisions — delivering a no with a route back, and a yes with its conditions intact, to people who remember how it was done for twenty years.

The first two can be started before anyone hires you, which is what the Three Diagnostics calculator and the drills are for. The second two are learned on a live portfolio, and no page will pretend otherwise.

The fastest way to know whether this work suits you is not another description — it is doing the unit of work once. A drill is a borrower's file compressed to its decision: the setup, the data on the table, four defensible calls, and the senior banker's reading after you have committed to yours.
