BaFin Record-Keeping Requirements for Financial Services Firms

BaFin’s stringent record‑keeping requirements focus on a firm’s ability to reconstruct regulated activity—not merely retain records—by showing who knew what, when, and what actions were taken. 

What are Core Record Keeping Expectations Under BaFin?

BaFin’s record-keeping framework is designed to enable reconstruction of regulated activity—not simply confirm that records exist.

Firms must demonstrate that records are:

• Complete — providing a unified view of trading activity, insider governance, and communications, not isolated datasets
• Retrievable — accessible on demand, without delay or manual assembly
• Reconstructable — capable of showing who knew what, when they knew it, and what action was taken

Under MAR supervision, insider list data must be retained for at least six years, with access history maintained throughout. Communications recording rules—aligned with MiFID II as implemented through WpHG—require firms to capture business-related voice and electronic communications intended to lead to a transaction.

Recent Examples of Enforcement Under BaFin Record-Keeping Requirements

Recent enforcement actions have made it clear that recordkeeping failures will not be tolerated. Often, administrative fines for record-keeping failures are bundled into actions for broader MiFID II or organizational breaches.

• In February 2025, a large retail banking group in Germany was fined €4.6 million for failing to record client telephone conversations related to investment advice: BaFin enforcement notice
• In March 2025, a large German banking group was fined €23.05 million for organisational and conduct failures, including the failure to record client telephone conversations: BaFin enforcement notice
• In April 2025, a Frankfurt-based bank was fined €395,000 for governance and AML shortcomings, including failures related to telephone recording disclosures and record-keeping controls, as published by BaFin: BaFin enforcement notice
  

 
Where German Firms Fall Short Under BaFin Audits 

German firms often meet retention rules at first glance but fail BaFin audits because records cannot be retrieved and linked under supervisory request. 

When firms manage critical areas of compliance, for example, insider lists, trade records, and employee communications, across separate systems with no unified retrieval capability, consistent gaps will be evident:

• Audit responses that depend on manual reconciliation across platforms lead to inconsistency and missed data
• When retention settings differ across systems, the same event may be preserved in one record and absent from another
• Without a single linked audit trail, firms cannot demonstrate—quickly and definitively—the chain of access, decision, and communication

For example, when reviewing a potential insider trading event, BaFin may request the insider list, related employee trades, and associated communications. When a firm is dealing with multiple siloed compliance platforms or manual processes, these records must be assembled manually across systems—often producing incomplete timelines and conflicting data points.

This is not just a technology failure. It is a governance design failure. The data exists; the architecture to make it supervisory-ready under BaFin requirements does not.
