AI Adoption in Luxembourg's Financial Sector Hits 43%
A recent survey by Luxembourg’s Central Bank (BCL) and the Financial Sector Supervisory Commission (CSSF) reveals that 43% of financial institutions in the country are now using AI solutions. This marks a notable increase from 30% in the previous survey, reflecting a clear shift toward integrating AI technologies in banking and finance.
The survey, conducted in summer 2024 with 461 participating institutions (86% response rate), identified 402 AI use cases. Over half of these are already operational, primarily focused on internal applications like process optimization and employee support rather than direct customer services. This indicates that AI’s initial impact is on improving efficiency behind the scenes.
Efficiency and Data Challenges Drive AI Use
Financial institutions cite three main benefits from AI adoption: improved internal processes, cost reduction through optimized operations, and enhanced data analysis capabilities. However, data-related challenges remain significant obstacles. Data quality tops the list, followed by concerns around data protection and governance.
Investment patterns show that nearly half of the institutions (46%) invested in AI or blockchain technologies through their parent companies, while only a small fraction (4%) made local investments exclusively. A third of the institutions had no AI-related investments in 2024, mostly fund managers and some investment companies. Banks and payment providers are leading the charge.
Looking ahead to 2025-2026, AI investment is expected to accelerate, especially locally in Luxembourg, driven largely by generative AI technologies. International groups seem to maintain steady AI spending, focusing on scaling existing projects to local entities.
Generative AI Takes the Lead
Since the release of advanced conversational AI models like ChatGPT in late 2022, generative AI has surged in financial services. The report highlights that 61% of AI use cases now incorporate generative AI, including text generation, image creation, chatbots, and code generation.
Common applications include automated document summaries, content creation for reports, next-generation customer service chatbots, AI-enhanced translations, and software development assistance. Traditional machine learning remains vital, especially in risk management, fraud detection, anti-money laundering (AML), and terrorism financing monitoring.
Combining generative AI with machine learning is creating more sophisticated tools, such as surveillance systems that analyze documents and communications for suspicious activity. Business functions are also exploring AI virtual assistants for tasks like information synthesis and script coding. Credit scoring remains limited due to regulatory concerns but is closely monitored as high-risk under future EU rules.
Policies, Training, and Security on the Rise
Most institutions (84%) have implemented or plan AI training programs, ranging from basic awareness to advanced technical courses. Nearly half (43%) have formal AI policies governing ethical use, bias management, and model validation—a number growing steadily from previous years.
Security measures specific to AI vulnerabilities have seen a sharp increase. Over half (54%) of firms have adopted protections against adversarial attacks and model drift, with banks and payment institutions leading at 66%. These precautions reflect growing awareness of AI risks.
Building AI Skills and Governance
About 63% of AI-using institutions have dedicated data science teams, mostly centralized at group level (55%). Only a small number (3%) operate AI teams directly in Luxembourg. Many rely on turnkey generative AI solutions, which require fewer in-house experts.
Data science teams tend to be small (usually under 10 people) and often report to IT departments, although a third have mixed IT-business reporting lines. This structure supports pragmatic integration of AI aligned with business needs.
Importantly, human oversight remains critical. Most AI processes include human intervention or validation stages to maintain control and accountability. This model aligns with regulatory expectations for trustworthy AI.
