Hahaha, nope. It's easier and cheaper to train a copule of COBOL programmers than replace the systems that run COBOL.

At a previous company I worked for, it was estimated that the cost to replace just a single COBOL based system was upwards of $50 million.

Not only that, banks are notoriously risk averse, especially with their software. They are very reluctant to change things that already work.
