Germany’s latest 30-year government bond auction showed a notable increase in long-term borrowing costs, with the yield rising to 3.900%, up from the previous level of 3.650%. The new figure reflects investor demand and pricing at the auction for ultra-long-dated German debt.
The updated data, recorded on 16 September 2026, indicates that investors now require a higher return to hold German 30-year Bunds compared with the previous auction. This upward move in the yield suggests a shift in market expectations around long-term interest rates and inflation, as well as broader conditions in the euro area’s sovereign bond market.
