But most hosting providers allow you to just rent a server for a day or a few hours, so it's not really an argument why you have to use the cloud.

Anything that wants to adhere to GDPR should still be very careful, if not outright avoid, AWS and Azure. At most one could use an EU-isolated offspring of them, otherwise one runs into the insanity of US laws. The fact that many businesses don't care doesn't make it right.
The actual hardware (or virtual these days) is not the problem, but getting the 5000-10000 services properly connected with auditing, credentials and more is more trouble than most people expect.
Finance is a heavily regulated industry, so there’s a LOT of compliance that needs to happen, like segregation of duty, traceability, accountability, and other ilities.
Yes, it would probably cost less to run on Hetzner (provided their ISO audits are approved by financial authorities), but dynamically spinning up and down servers would cost more.
You also need fallback plans (regulated industry, critical infrastructure, etc).
It has literally taken years to get AWS and Azure approved in EU.
