Europe's top bank supervisor is weighing a check on data center loans, to see how banks would cope if AI excitement and company values swing.
The European Central Bank is thinking about taking a closer look at how much its banks have lent to data centers. These are the large buildings full of computers that power artificial intelligence. Bloomberg Technology reported on November 6, 2026, that the bank's supervisory arm is considering a review. Nothing has been confirmed.
The ECB's supervisory arm is the part that watches over banks in the euro area. It wants to gauge the risk from swings in AI sentiment, meaning how excited or nervous investors feel, and in valuations, meaning what AI companies are judged to be worth.
In plain terms, the aim is to test how banks would hold up if AI hype cools or company values drop.
If AI spending slows, banks that lent heavily to it could tighten credit. That means lending less or making loans harder to get. It could affect business loans and market confidence, even for companies with no link to AI.
The idea is only under consideration so far. Until the ECB says more, it is best read as a sign that regulators are watching AI-linked debt, not as a sign of a problem.
The ECB is only weighing a review, but it shows regulators are asking how exposed banks are to AI spending.
