Compliance & Regulatory Data Protection & Privacy Last reviewed: 2025-09-05 Owner: Data Protection Office

1. Purpose

This policy (Ref: COMP-DP-003) defines the Bank's standards for the retention and secure disposal of personal data and business records. It ensures compliance with the GDPR's storage limitation principle (Article 5(1)(e)), applicable financial services regulations, and the Bank's record-keeping obligations under AML, tax, and prudential legislation.

2. Scope

This policy applies to all data and records held by the Bank, whether in physical or electronic form, across all business lines, systems, and jurisdictions. It covers customer data, employee data, transaction records, communications, and operational documentation.

3. Core Principles

  • Personal data must not be retained for longer than is necessary for the purposes for which it was collected.
  • Where multiple retention requirements apply to the same data, the longest applicable period shall prevail.
  • At the end of the retention period, data must be securely destroyed or anonymised unless a legal hold or regulatory requirement mandates continued retention.
  • Retention schedules must be documented, regularly reviewed, and accessible to Data Owners.

4. Retention Schedule

The following table sets out the minimum retention periods for key categories of data. Business units must consult the full Retention Schedule (Annex A to this policy) for a comprehensive list.

5. Legal Holds

Where data is subject to a legal hold (e.g., litigation, regulatory investigation, or law enforcement request), the applicable retention period is suspended. The Legal Department must issue a written legal hold notice to all relevant Data Owners and the Data Protection Office. Data subject to a legal hold must not be deleted or modified until the hold is formally released in writing.

6. Secure Destruction

At the end of the retention period (and in the absence of a legal hold), data must be securely destroyed:

  • Electronic data — Must be permanently deleted using approved data wiping tools that meet the NIST 800-88 standard. Certificates of destruction must be retained.
  • Physical records — Must be cross-cut shredded by the Bank's approved secure destruction provider. Certificates of destruction must be retained.
  • Backup media — Data on backup tapes and archives must be overwritten or destroyed in accordance with the IT Security Policy (IT-SEC-003).

7. Responsibilities

  • Data Protection Office — Maintains the Retention Schedule, provides guidance, and monitors compliance.
  • IT Department — Implements technical controls for automated retention and deletion.
