That's not reinventing the wheel, that's building a new wheel you hope performs better/different with different materials and maybe some different techniques, and has a long and storied history of both successes and failures.
Reinventing the wheel would be if they published this system and some other bank recreated it without using what they published, thus "inventing" something that already existed and was available.

I never realised Kapital was written in smalltalk. Interesting

Apparently when it booted in the terminal, there was a nice ASCII portrait of Marx. I also have it on good authority that the program that launched the Smalltalk image from the terminal was called "das," so you literally would type "das kapital" to get the thing going.
That system you're thinking of was Kapital.

It's the only Smalltalk usage at JPM I believe, they could have doubled-down on it but instead went to Python and as you say, tried reinventing the wheel in it.
