Nexus 2025 | ABBL, PwC & ACA survey on data maturity, AI and compliance

Published on 16 June 2025

At Nexus 2025, the ABBL, PwC Luxembourg and ACA brought together financial sector leaders to explore the findings of their joint 2025 (Gen)AI and data use survey. Based on 101 responses, including 74 from regulated institutions, the study highlights how Luxembourg's financial actors are managing data governance, AI integration, and regulatory preparedness. It also complements the CSSF/BCL thematic review on the use of artificial intelligence in the financial sector, which identified data quality and infrastructure as the number one obstacle to successful AI deployment. The Nexus panel, moderated by Andreas Braun (PwC Luxembourg), included insights from Jacques PĂĽtz (Spuerkeess), Anne Goujon (BGL BNP Paribas), Ian Atkinson (Governance.com) and Pascal Bughin (AG2R La Mondiale).

Summary

    Key data takeaways

    The findings reveal uneven progress across the industry:

    • Only 25% of respondents report high maturity in data use
    • 88% collect data primarily to improve operational efficiency
    • Many still rely on Excel and traditional BI tools
    • ESG data capabilities remain underdeveloped
    • Fewer than one in three use advanced tools like data lakes or master-data platforms

    Panellists confirmed that data quality and governance are still weak points for most institutions. Rather than aiming for “perfect” data, participants suggested focusing on well-scoped, prioritised data sets, supported by continuous governance and cross-team collaboration.

    Preparing for AI – responsibly

    The upcoming EU AI Act will require firms to explain not only their models, but also the origin, governance and reliability of the underlying data. Building on the CSSF/BCL review, both the survey and the Nexus discussion underscore that:

    • AI maturity depends on internal data literacy and strategic alignment
    • Clear employee guidelines are needed for responsible GenAI usage
    • Use cases gaining traction include document processing, internal virtual assistants, and control functions
    • Regulatory expectations include transparency, secure-by-design development, and risk-based implementation paths

    This year’s findings show big strides on data governance, but also remind us how much value is still locked away in under-used data sets. Our priority is to help members turn that data into smarter services for customers and more efficient operations for banks.
