Best Programming Language for Banking & Finance

When starting to write an investment banking program, the first aspect that many developers think about is what programming language to use. Thankfully, there are people who have taken the dive and tried all kinds of different programming languages, all of which have worked in their own unique way.

Let’s take a look at the best programming languages for Investment banking technologies.

1. Python

It’s no surprise that Python has been in most programmers heads at one point or another. Python has truly taken the world over in terms of programs that are using it, that people use every day, all without knowing it.

Python specifically has been used in Investment banking technologies as it’s very efficient in being programmed in such a way that allows for machine learning and AI applications. In Investment banking, one of the most important attributes are the numbers, and Python is more than capable of keeping up. Python uses a colossal amount of libraries, so running financial data and statistics is a breeze.

Python has one of the vastest libraries for modules. This means that if you need a particular script or scripting module, the chances are that there is a very good chance that it already exists. Python is super easier to learn too, and there are millions of places to get content on how to learn Python, specifically to make Investment Banking applications.

2. Java

Java is another heavily used programming language that is used by millions daily. With that being said, Java is also used quite often in the financial sector, specifically Investment Banking. Many main-stream banks use Java as their online trading platforms and banking portals.

Java is mainly used as a front-end or customer-facing programming language, which may mean you need to tie it to another programming language to utilise it to the best it can be. Java also utilises concurrency, allowing for the program to operate several events at any one time, so can be used for high-intensity events and activities.

As we’ve mentioned at the start of this Java section, many major banks use Java as it’s the main framework for investment banking. Banks like Goldman and Morgan will be continually looking for Java developers, as their frameworks run on Java, prooving that even the big dogs use Java for their investment banking applications.

3. JavaScript

A slight variation of the above, JavaScript (JS) is another programming language that has been linked to Investment Banking applications for quite some time. Newer frameworks for JavaScript such as AngularJS, ReactJS and jQuery has made JavaScript one of the most significant client-side validation programming language in the world.

Learning JavaScript will be crucial if you ever wish to touch on website development or a website side of an application for an investment banking application, and so learning JavaScript will be a solid foundation, even if you’re a beginner.

3. C# (C-Sharp)

Covering even more major programming languages, C# when combined with .NET is a very popular programming duo for investment banking, even more so for when creating a client-facing interface.

C# has many other use-cases, but primarily for investment banking, C# is effective at creating a Windows side application. As the .NET framework is based on C#, there is very little reason not to give C# a go for your programming language, for investment banking.

4. C++/C Programming

Another C-style language, C++, is used in Investment banking all over the world. This is in part to the speed and efficiency of the language. Using C++ in Investment Banking will allow the programmer to create low-latency trading so bids can be placed quicker than other applications.

C++ programming can be a little more complicated compared to other programming languages on this list. Still, thankful, there are so many books and courses that allow you to learn C++ effectively, and in a matter of months.

5. VBA (Visual Basic Applications)

A slightly uncommon, but still occasionally used choice for investment banking applications, VBA or Visual Basic Applications is a programming language that intertwines with Excel. Investment Bankers use VBA all the time, as it’s already built into most fintech systems.

The main part of VBA that makes it great for investment banking is the Macros system. Macros can be used for data handling, error logging, models that are creating using VBAs core systems, risk management, investment risk, investment strategies, and so much more.

VBA is also a way to automate your investment banking, or at least the redundant, spreadsheet work. This can be beneficial for your time, as you can invest more time into learning other programming languages or expanding your knowledge on VBA.


Programming languages are used in Investment banking all the time, and using one of any of the above can be beneficial for both time, and productivity. All the languages are relatively easy to learn too, meaning you can get started today.
