Europe faces a growing risk of being cut off from artificial intelligence systems that will soon control critical infrastructure, from border screening to hospital patient monitoring, European Central Bank President Christine Lagarde warned on Monday.
Speaking in Vienna, Lagarde said European firms import most of their AI technology from overseas - particularly the United States - creating a single point of failure that no trade partner has ever held over the continent before.
"A withdrawal of access, or a change in its terms, would then reach every sector at once," Lagarde said. "That is leverage of a kind no trade partner has ever held over Europe, and it could be used in any negotiation, on tariffs or on digital taxes, for example."
The infrastructure gap
Europe already lacks the data centre capacity to meet its own computing demand. Lagarde said that on current trends, the shortfall will grow more than sixfold within a decade. The solution, she argued, is building European computing infrastructure and developing AI models that are "good enough" for most tasks - models that run on European systems so the threat of losing access loses its force.
If Europe adapts quickly, AI could lift productivity by up to 4% over ten years, a shift Lagarde described as transformative for public finances. The ECB president pointed out that European firms and governments are already paying for the technology in less visible ways. U.S. tech companies, facing enormous investment needs, are borrowing in European debt markets, pushing up costs for other borrowers. European pension funds also hold large positions in U.S. tech stocks, meaning any market correction would hit European savings directly.
Geopolitical context
While the EU and the U.S. remain key allies, trust has eroded over tariffs, demands by the U.S. to take over Greenland, and the withdrawal of American troops from Europe over political disagreements. Lagarde's speech framed AI dependency as the next front in that strained relationship - one where the leverage sits almost entirely on one side.
Within a few years, she said, AI will be "screening goods at the border, deciding which tax returns are audited, dispatching trains, watching patients on wards and clearing payments at banks." A disruption would not hit one industry. It would hit all of them simultaneously.
Why this matters for finance professionals
For CFOs and finance leaders, Lagarde's warning carries two immediate implications. First, the productivity gains she cites - up to 4% over a decade - represent a direct margin opportunity for firms that integrate AI into financial operations, compliance, and planning. Second, the concentration risk she describes is not theoretical. European companies that depend on U.S.-based AI services for payment processing, fraud detection, or tax compliance are carrying a supply-chain risk that has no easy backup. Understanding where your organisation's AI dependencies sit - and what happens if access changes - is now a board-level question.
