What is the front office, middle office, and back office of a bank?

It can be hard to understand what is going on exactly in an investment bank. There are a lot of roles that are directly relevant to the bank’s operations, some that seem to directly support them, and some seemingly generic ones.

Luckily, there is a straightforward (ish) way to define what each people do in a bank: the front-, middle-, and back-offices. These are not actual places; they are functions which describe particular sets of jobs done in banking.

More confusingly, banks almost never use the terms themselves. This is because "back office" and "middle office" are considered derogatory in the same way that it was considered derogatory when Standard Chartered CEO Bill Winters referred to "lower value human capital" (meaning the back and middle office). 

What is the front office of an investment bank?

Front office jobs are generally the easiest ones to define. They are client-facing and revenue-generating; a senior banker in London says that, historically, “front office jobs in investment banks were those trading on behalf of the bank, or directly working with clients or creating products, research or analysis for them.”

Another senior banker agrees. He says front office jobs were always any that involved "direct interaction with the client and customer - be that an individual or a corporate client."

What jobs does that cover specifically? In an investment bank, it means mergers and acquisitions (M&A), debt and equity capital markets (DCM and ECM, respectively), as well as sales & trading roles, even if you do spend that “client-facing” role as a junior carrying your boss’ briefcase and building financial models by yourself at night.

Front office banking jobs are the most prestigious and the highest paid. If you work in sales & trading in a bank, you might earn $837k as a managing director. If you work in investment banking, you could earn up to $1.2m.

What is the back office of an investment bank?

The “back office” generally refers to what’s going on behind the scenes at an investment bank. These are support roles. Nowadays, a lot of the work done is far from glitzy London or New York but in offshoring paradises such as India (home to 55,000 JPMorgan employees) and Poland (home to 8,000 UBS people).

What sort of jobs are those tens of thousands of back-office people doing? A variety. Settlements, for example – making sure that payments for trades are processed and trades go through accurately.

Back-office jobs aren’t really seen as sexy. They’re not as desirable, but banks do their best to make them seem interesting. There might be something to their historic stigma, however. "I worked in trade support covering settlements for a French bank in London," says one operations analyst. "It was all very static, and process driven - I spent all day analyzing exception queues from various systems and analyzing trades to make sure they were settled properly. It was a repetitive job with very slow career progression."

What is the middle office of an investment bank?

As the name suggests, the middle office is somewhere between the front and back offices.

The front office might be easy to identify, but the middle- and back-office distinction is less clear-cut. Strictly speaking, the middle office’s role is to directly support the front office.

Which kinds of people in banks directly support the front office? Risk management professionals maybe? Or someone in compliance? Or even in technology…? Kind of. The problem with these definitions is that not all risk, compliance, or tech people support the front office directly – although some do. That blurs the lines a lot.

"It's perfectly possible for a risk person to be either in the middle office or the back office," says one senior banker. "You might get a risk professional sitting on the trading floor, in which case he or she would be a middle office person. And then you might get a risk person miles away in the corporate center, in which case they'd be in the back office."

What's the difference between front, middle, and back office?

What we’ve outlined above is what the office split really used to be. Things have changed, and are continuing to change, and the reason for that is, as always, technology-related.

Banks are very, very keen to automate as much as they can. Technology can save money, for one, and make fewer mistakes. It also can lead to better productive results than brainpower. Goldman Sachs replaced 600 equities traders with electronic trading systems back in 2000, and it hasn’t looked back since.

Engineers are taking over more and more of the front office’s territory, too. In 2014, Goldman introduced Marquee, a “digital storefront” for Goldman clients to access the bank’s pricing and risk information directly instead of via a salesperson. Goldman has since added AI capabilities to Marquee's abilities - including overlaying geopolitical events that automatically impact a change in the price of a security or derivative. Chris Churchman, Goldman's head of Marquee, told Business Insider that he saw Marquee's role in an investor's day as "just like Amazon.com's." There's not much need for humans to intervene in a purchase at Amazon.

What type of job you have might be easiest defined by your physical location. Back-office jobs are almost uniformly in low-cost centers such as India, Poland, or Birmingham. Front-office jobs are almost uniformly in important financial nodes such as Hong Kong, London, or New York. Middle-office functions are generally close to front-office ones.

How are the front-, middle-, and back-office changing?

Artificial Intelligence (AI) is changing the world, and process-oriented middle- and back- office jobs are at the forefront of the changes.

HSBC proposes to cut 20,000 jobs in the next three to five years through the deployment of AI and many of the jobs that go are expected to be in the middle and back office. Goldman Sachs has identified six workstreams that it says are particularly susceptible to AI disruption, and none are in the front office. Instead, they are client onboarding/KYC, vendor management, regulatory reporting, lending, enterprise risk management, and sales enablement.

As AI tools take over, some professionals in the middle and back office say that their jobs are being dumbed down. One risk management professional told us that the “aggressive” pace of technology rollout and cost-cutting and offshoring had “significantly weakened” the effectiveness of his team. “The actual purpose of the role - thoughtful credit analysis and risk judgement - is steadily being displaced by operational firefighting,” he said. Many risk analysts at his bank now spend the majority of their time fixing AI errors. Of JPMorgan’s 80 open roles for “control officers”, 28 contain the word “AI” in the description. 

This isn't to say that AI can't replace front office bankers too. Earlier this month, Anthropic, which runs Claude, released ten “ready-to-run” agent templates that can make pitchbooks, build financial models, and check valuations against comparable ones, among others. Much of this work is done by junior investment bankers in the front office. 

It’s not just bankers. Sales and trading jobs are also at risk. In an interview with Stanford Business School earlier this month, Ken Griffin, CEO of hedge fund Citadel, said AI had become “profoundly more powerful” within the last few months. Griffin said this had allowed Citadel to significantly its uses to "highly skilled jobs."

“To be blunt, work that we would usually do with people with master’s and PhDs in finance over the course of weeks or months is being done by AI agents over the course of hours or days,” Griffin added. The implication is that work done by Citadel's analysts and traders may also be done by AI in the future. 

Working hours and pay in different parts of the bank

With functions so different (and office space so variable in cost), it’s no surprise that the different functions of an investment bank are paid wildly differently – and work different hours.

Our 2026 Compensation & Lifestyle Report showed that it was front-office staff, and especially investment bankers, who worked the longest hours and were among the best compensated. Bankers in our report worked for 62 hours a week, on average.  

Middle- and back-office people worked much more reasonable hours. For example, middle-office compliance professionals worked for 43 hours a week, on average, and back-office technologists worked 44 hours a week, on average. 

The holy grail in our report was sales & trading, a front-office function that was paid as a front-office function – but had much more reasonable hours on average. There was variety within sales & trading by product group for both pay and lifestyle, however.
