On July 20, 2026, Greece published Law 5321/2026 (Official Journal A' 114) to implement Regulation (EU) 2024/1689 of the European Parliament and of the Council on artificial intelligence (AI Act). The Hellenic Banks Association (HBA) published notice of the law on July 22, 2026. Law 5321/2026 transposes the EU AI Act into Greek national law and amends Law 4961/2022. The legislation comprises 26 articles establishing implementation measures for the AI Act across Greece's regulatory framework. The law addresses the governance, risk management, and compliance requirements for artificial intelligence systems used by regulated entities, including financial institutions operating within Greece's banking sector. The AI Act establishes a risk-based approach to regulating artificial intelligence, requiring organisations to implement appropriate safeguards proportionate to the risks posed by their AI systems. Key provisions address transparency requirements, algorithmic accountability, bias mitigation, and data protection obligations for entities deploying AI applications. The regulation applies to a broad range of sectors, including banking and financial services, where AI systems may impact consumer protection and market integrity. Financial institutions and other regulated entities subject to Greek law must ensure compliance with the new requirements. The implementation of Law 5321/2026 establishes the legal framework through which Greece's financial regulators will oversee AI governance and enforce compliance with the EU AI Act. Entities should review their existing AI systems and governance structures to ensure alignment with the law's requirements and begin implementing necessary compliance measures.
