Python Reigns Supreme in Finance: A Tale of Two Cities

As a journalist covering the intersection of finance and technology, I’ve always been fascinated by the coding languages that dominate the job market. Recently, I delved into the world of finance to uncover the most sought-after programming languages in London and New York, the two global financial hubs.

Financial centers of the world

Using data from workforce intelligence firm Revelio Labs, I examined which programming languages appear most frequently in job listings for technology roles in finance in each city. The results were intriguing, to say the least.

Python Takes the Crown

Although SQL is the most commonly requested language in finance worldwide, Python reigns supreme as the most desired financial services coding language in both London and New York. In fact, Revelio’s data suggests that Python is requested in over 23% of jobs in New York and well over a quarter of jobs in London. This is hardly surprising, given Python’s versatility and ease of use.

Java’s Mixed Fortunes

Java, on the other hand, seems to be a language out of fashion in finance jobs these days – unless you’re in New York City. Revelio’s data suggests that Java jobs are falling globally, both in and outside of finance, but New York appears to be one of the few places where demand is going up. Java was requested in 14.1% of financial technology jobs in New York in 2023, and 14.9% in 2024.

C++ Makes a Strong Showing

C++ had a conspicuously low percentage in our global rankings, but it’s much more prominently featured in the two big financial centers. C++ is the sixth most requested language in New York and the seventh most in London.

C++’s resurgence in finance

As I reflect on these findings, I’m reminded of my own experiences in the finance industry. I recall working with a team of developers who were struggling to implement a new trading platform using Java. It was a painful process, but eventually, we switched to Python, and the project took off. It’s no wonder that Python has become the language of choice for many finance professionals.

In conclusion, the world of finance is constantly evolving, and the coding languages that dominate the job market are no exception. As we look to the future, it’s clear that Python will continue to play a starring role in finance, while Java and C++ will likely have their own niches to fill.
