Rehn Says 3.57% Bund Yield Is Doing ECB Tightening Work as AI Debt Crowds Bond Markets

Summary
German 10-year Bund yields near 3.57%—their highest since 2009—are already tightening eurozone financial conditions enough to do part of the ECB’s job, Olli Rehn said before the Oct. 29 rate decision.
Rehn argued that while higher energy prices are lifting inflation risk, higher long-term yields are simultaneously slowing growth and limiting the pass-through of that shock into wages and broader prices.
Eurozone inflation hit 3.2% in August, with energy inflation at 14.3%, after the ECB had already raised its deposit rate twice this year to 2.50%; markets still price a 60% chance of another 25-basis-point hike.
AI infrastructure borrowing is a key driver of the selloff: hyperscalers are on track to issue about $500 billion of bonds in 2026, crowding sovereign debt out of global capital markets and lifting borrowing costs across Europe.
Rehn also warned that a sharp AI valuation correction could spread through equity and credit markets, complicating ECB policy if an energy-driven inflation fight collides with a market-led credit tightening.
