Commercial Banking vs Investment Banking

A declared bias, so you can weigh it: this site is written by a commercial banker and teaches commercial credit judgment. The comparison below is made carefully anyway, because the common framing — investment banking as the destination, commercial banking as the fallback — is not a bias, it is an error, and it costs candidates on both sides of it.

The commercial banker's week is built around borrowers who exist whether or not any deal is live: reading financials, structuring facilities against real cash cycles, writing credit papers, watching a portfolio for the early signals of trouble, and sitting across the table from owners whose businesses the bank will be funding through several cycles. The interesting problem is rarely whether a business is good — it is whether a good business can be financed in a form an institution can hold. What that looks like in practice is set out in what does a commercial banker do.

The investment banker's week is built around live transactions: models, materials, process management, negotiation support — intense, episodic, and organised around a closing date. The craft is real and the hours are the market's worst-kept secret. When the deal closes, the team moves to the next one; the client relationship belongs to the franchise more than to the analyst.

The two disciplines select for different muscles. Investment banking runs on technical fluency and execution stamina — valuation mechanics, document discipline, speed under deadline. Commercial banking runs on judgment under incomplete information: the same borrower file supports several defensible readings, and the job is to commit to one and be movable by evidence rather than pressure. One skill set has checkable answers; the other has defensible ones.

The interviews mirror this exactly. IB interviews test technicals that can be — and are — prepared from specialised sources. Commercial banking panels hand you a file and watch you read it, which is why preparing for a credit seat with a memorised DCF fails so reliably. The commercial genre is mapped in commercial banking interview questions, with role-specific pages for credit analysts and relationship managers. For IB technicals, use sources that specialise in them — nothing here will help, and this site says so rather than pretending otherwise.

Investment banking careers are a tournament: structured analyst classes, up-or-out rhythms, and an expectation that many will exit into private equity, corporate development, or funds — the exit itself is part of the product. Commercial banking careers compound differently: an analyst becomes a lender, a lender takes a book, a book becomes a client base that travels with you, and the senior roles — running credit, running a portfolio, running a market — are mostly filled from within the discipline rather than exited to. The full ladder, stage by stage, is in commercial banking career path.

Neither shape is better. One front-loads intensity and optionality; the other rewards accumulated judgment and relationships that appreciate. The honest question is which curve you want to be on at year ten, not which is harder to enter at year zero.

Most interview-preparation content is written from inside the investment banking funnel, and from there commercial banking is visible only as the thing you do if IB does not work out. Taken as career advice, that framing fails a simple test: the two jobs select for different skills, so “fallback” is a category error — a strong deal executor is not automatically a competent reader of credit, and treating one craft as the other's consolation prize prepares you for neither.

It also produces a practical failure this site sees constantly: candidates arriving at commercial banking interviews with the wrong preparation entirely, fluent in accretion math and unable to say what a lengthening cash conversion cycle means for a facility request. If commercial banking is your target, prepare for commercial banking — as a first choice, with its own genre. That is the gap this site exists to fill.

A rough sorting, honestly meant. If you are energised by transactions — the sprint, the closing, the next deal — and you want maximum optionality at twenty-five, the investment banking funnel is built for you and its price is known. If you are energised by businesses — how they make money, why they run out of it, what a bank can safely do about it — and you want a craft that compounds with the same clients over years, commercial banking is not the consolation prize. It is the job.

The cheapest way to test the second instinct is to do the work once: read a case file, make the call, and see whether the senior banker's reading afterwards feels like an answer key or like a craft you want. That reaction is data.

The page above argues in shapes; this section gives the numbers that can be sourced, with their geography and date, and says where a number does not exist. Salary figures are base pay per annum, exclusive of superannuation, bonus and benefits, from the 2026 column of the Robert Walters Australia & New Zealand Salary Guide 2026, which draws on its annual survey and an analysis of advertised roles across the two countries.

What the guide does not tabulate is a front-office investment banking analyst or associate in either city. Neither the Robert Walters guide nor the Hays FY24/25 Australia and New Zealand guide carries an M&A or capital-markets desk line, so this page does not print one; aggregator figures exist but are self-reported and are not cited here. The claim that early-career cash pay in investment banking is higher stands on the structure of the job rather than on a table.

Hours. The published record for investment banking is unusually direct. A self-selected group of thirteen first-year Goldman Sachs analysts reported an average working week of 95 hours to management in February 2021. In September 2024 JPMorgan capped junior banker hours at 80 a week in most cases, and Bank of America began requiring daily hour logging by deal. No comparable published series exists for commercial banking relationship or credit seats; the honest statement is that the week is a working week with peaks around annual reviews and deal closings, not a deal week.

Attrition. The one tracked cohort in the public record is old but specific: a private-equity recruiter followed 250 analysts who joined six leading banks' London M&A and corporate finance teams in 2010 and found that 44 per cent had left banking within three years. Nothing of that shape has been published for commercial banking; the career-path page on this site describes the ladder qualitatively for that reason.
