CBUAE Notice 4140 Core Systems Readiness & Independent Validation Services in UAE 

Reading time: 5 minutes
The Central Bank of the UAE (CBUAE) issued Notice No. 4140 on July 25, 2025, mandating Licensed Financial Institutions (LFIs) to ensure efficient and effective deployment of core banking systems, customer information systems, and transactional systems.

This directive emphasizes resilience, risk management, independent quality assurance, governance, and regulatory reporting to safeguard consumers and financial stability amid the evolving financial and fintech landscape in the UAE.

Key CBUAE Notice 4140 Requirements for UAE Financial Institutions

LFIs must align core systems to the latest vendor-supported versions or engage independent third-party evaluations for in-house systems. Risk reports must be submitted to the CBUAE within specified timelines.

Material system changes require:

• Pre-production testing and documented impact assessments
• Rollback strategies and parallel runs
• 30-day prior notification to the CBUAE
• Independent external expert assessments
• Comprehensive vulnerability and penetration testing
• Restricted administrative access controls
• Robust audit logging in production environments

For new system implementations or migrations, LFIs must submit a Letter of Intent at least 60 days prior to go-live. This includes:

• Board-approved business case
• Project governance structure
• Defined timelines
• Engagement of independent external assurance providers acceptable to CBUAE
• External assurance typically covers:
• Analysis and system/vendor selection review
• Strategy and project planning oversight
• Governance and risk management validation
• Testing and data migration readiness assessment
• Go-live readiness and reporting

Upgrades follow similar regulatory protocols, including independent validation and post-upgrade assurance reporting.
