A Day in the Career of an Investment Banker

Why do Investment Bankers Work so Much

An investment banker’s employment requires them to spend less than half of their time conducting genuine analysis, which is a little-known fact. The following is a breakdown of their typical day:

  • For Pitch Books and Other Presentations, PowerPoint gets used 50% of the time.
  • Random and administrative tasks account for 30% of the workload.
  • Excel gets used about 20% of the time. Modeling and Valuation of Financial Assets
  • This usual weekday starts late in the morning, about 9:00 a.m. But it won’t be over until after the sun has set. At this point, every other company has gone out of business. Furthermore, everyone else had retired to their beds. Even the night owls have been sleeping for quite some time. However, there is nothing on a regular weekday, so that depiction isn’t realistic. Because of the nature of financial services, there are constantly unexpected events that need additional time and attention. This may include handling numerous negotiations simultaneously to pulling an all-nighter to finish that last-minute pitch deck. This is not a viable way of life. Fortunately, it doesn’t last forever since most analysts move up the corporate ladder after a few years.

Why do Investment Bankers Work so Much

Because of the following factors, investment bankers work a lot:

A large clientele

Unlike a typical business that sells things, bankers must react to every customer request since they sell their time and attention rather than a commodity. So, if your MD calls you at 7 p.m. on a Saturday to tell you that a board presentation is required the following day, you must comply.

Like consultancy or law, there is limited leverage since higher money equals more hours and labour. There are several service-based sectors where “customer service” is lacking.

Investment banking, on the other hand, is not one of them. If a single executive disagrees, there is just too much money (millions of dollars). This might alter if banks had a different business strategy, such as earning $50,000 each transaction and executing 1,000 of them each year rather than making two deals costing $25 million in fees each year.

However, this would be significantly less lucrative than what banks do now. This is why they cling to the strategy of “two agreements worth $25 million in fees each.” That is why they must fulfill all of their customers’ requests.

Unpredictable Demands

Another reason investment banker’s work so hard is because of unpredictably high demand. When working on an M&A transaction, for example, the majority of the work is done at the start. This is the time to start working on marketing materials and budget estimates.

Then, as the transaction nears completion, you get busy. However, the middle section usually does not need as much effort.

That’s almost to get expected. But the difficulty is that random events, demands, and problems constantly arise amid the process. You can receive an entire portfolio from a bidder who first declined but then returned at the eleventh hour.

Perhaps your client’s forecasts were off, and you need to redo your 22-page model entirely. Or maybe the Executive is just having a terrible day and wants to see some utterly pointless analysis for its sake. Your team will also make unpredictably high requests.

Sometimes you’ll have a VP or MD who constantly requests unnecessary tasks. This can occur at any time or night, and it may completely overwhelm you.

Failures in the Division of Labor

The issue with recruiting additional individuals in investment banking is that it’s tough to distribute work among multiple Analysts or Associates on a single project. Clients benefit from this for two reasons: accountability and knowledge.


A senior banker desires to go to one person in charge of everything if he needs something done. Not two or three people are involved in the project. Similarly, if an Associate requires a model, he only wants to enlist the help of one Analyst.

He doesn’t want to choose between two or three people who claim to be too preoccupied with other tasks to assist.

When some errors or adjustments need to get addressed, responsibility becomes even more concern. If many junior bankers are engaged, each one is likely to “blame” the others for whatever went wrong. For responsibility and getting things done, just one Analyst/Associate must get assigned to each customer.

Multiple junior bankers may get allocated to big or otherwise significant transactions in certain situations. However, they frequently focus on entirely separate project elements when this occurs. You can genuinely split the task since it is so significant.


Another issue with allocating numerous junior bankers to a single customer or transaction is that keeping everyone informed is tough. One Analyst may begin updating a model and then fail to notify the other.

This might confuse 3 a.m. when Analyst #2 attempts to correct a presentation using the model that Analyst #1 had amended the day before but hadn’t informed him about.

It also takes time to catch up on what’s been going on. This is in addition to the previous work you’ve done for a customer. Deciphering months or years’ effort takes more than a few hours or days.

Long hours of labour

Investment bankers who have worked in the profession for a long time are used to the concept that their colleagues work long hours. That’s simply the way it is, and it’s always been that way.

And this is one of the issues. Since senior bankers all worked overtime on their way to the top, there is a cultural conviction that, as a result, fresh entry-level bankers must go through the same ordeal. Junior analysts and colleagues aren’t the only ones that suffer.

Even senior bankers put in a lot of hours. While hours on the job and work-life balance increase with seniority, senior bankers still put in many hours. Because the supervisors work around the clock, junior bankers get expected to be available 24 hours a day to respond to their needs.

Working from home in the COVID age has just exacerbated the problem. Analysts are now required to reply immediately, regardless of the time of day or night.

Some may argue that the high income of an investment banker compensates for the arduous effort. However, only those who have experienced it can completely comprehend the magnitude of the strain.
