ECB's Lane: AI Now Drives Growth and Tightens Credit
AI is now a significant contributor to euro-area growth, ECB chief economist Philip Lane said on October 30. He also warned the global AI boom is pushing up long-term rates.
The European Central Bank's chief economist has started treating artificial intelligence as a macroeconomic variable rather than a technology story. "AI is currently a significant contributor to growth in the euro area, driven by both expenditure on AI adoption and the role of European firms in the global AI supply chain," Philip Lane said in a speech in San Francisco on Friday, October 30, Bloomberg reported. He spoke as a keynote at the Federal Reserve Bank of San Francisco's conference on the impact of AI on the economy.
The more market-relevant part of Lane's thinking came in Dublin on October 13. In prepared remarks for the International AI Summit, he said the global AI investment boom is "plausibly contributing to the global increase in long-term interest rates", and called that "a relevant factor for the ECB in determining the appropriate monetary policy stance", Econostream reported. The logic is simple: the euro area invests far less in AI than the United States, so it imports the higher bond yields that the American build-out creates without getting a matching investment boom at home. Higher long-term rates mean tighter financing conditions for European borrowers.
His figures show adoption is real but uneven. Firms are expected to devote about 10% of total investment to AI this year, and AI-related lending accounts for roughly a quarter of recent credit growth to firms. ECB surveys find 64% of firms using AI experimentally or moderately and 7% using it significantly, while the share of workers using AI at work doubled to 52% from 26% in two years. The gap with the US remains wide: digital investment there grew about twice as fast over two years, and US workers spend two to three times as much of their week using AI as workers in the largest euro-area economies.
Lane also named the risks. High equity valuations of AI firms and the global surge in AI-related debt "carry macroeconomic and financial stability risks" if expectations or investor sentiment reverse, he said, and the ECB's financial stability and supervision teams are monitoring AI-related financial and cyber risks. On the labour side, aggregate effects are limited so far, but hiring plans are muted, especially for new graduates, and AI could weaken workers' bargaining power and moderate wage growth.
For investors in European assets, the message has two sides. AI spending is now supporting growth, which helps the case for steady policy. But a central bank that sees AI-driven yields as a form of tightening is likely to watch US bond markets closely when setting its own stance, and a sharp reversal in AI valuations is one of the scenarios its stability teams are already preparing for.
