Banking institutions process trillions of dollars daily through systems that rely on complex mathematical operations — risk calculations spanning millions of variables, portfolio optimizations across global markets, and cryptographic protocols protecting customer data.

The banking angle is usually less "quantum computers make money go brrr" and more two boring buckets:

optimization/simulation problems where a useful quantum speedup would have to beat extremely good classical heuristics, not just a textbook example;
crypto migration, where the prudent move is inventorying systems and getting post-quantum paths ready long before anyone has a scary machine.

The second one is the near-term work. Less sci-fi, more spreadsheets, HSM firmware, certificate lifetimes, vendor archaeology, and discovering that a critical batch job still speaks TLS like it was raised by wolves.

If quantum changes banking, the first visible sign may be compliance people asking surprisingly good questions.
