What DeepSeek does in banking & fintech

Core tasks in banking & fintech
  • Identify and verify customers during onboarding (KYC/KYB, document checks, liveness)
  • Monitor transactions for money laundering and terrorist financing and reduce false alerts
  • Screen customers and payments against sanctions lists, PEPs and adverse media
  • Detect fraud, scams and account takeover in real time and investigate alerts
Where DeepSeek is strong
  • Very low API costs
  • Open weights (MIT), self-hostable
  • Strong at reasoning, maths and code
  • Large context window (1M tokens)

DeepSeek has a concrete GDPR concern. The DeepSeek service stores personal data in China and was blocked by the Italian regulator in January 2025. Not recommended for regulated sectors unless you host the model yourself within the EU. Weigh this heavily before using it in banking & fintech.

Confidentiality and GDPR

GDPR: Caution

You process identity documents, biometrics and transaction data: choose providers with EU data location, ISO 27001 and a data processing agreement, and ask whether customer data is used to train the provider's models. Outsourcing critical processes falls under the DORA and EBA rules, so secure exit and audit rights in writing. Creditworthiness assessment of natural persons is a high-risk application under the EU AI Act. For transaction monitoring, the supervisor expects you to explain why an alert is or isn't triggered, a human to decide on a report to the FIU, and that you test the model for unequal treatment of customer groups.

The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
