Germany's 30-year bond yield holds steady at 3.8%

The stable yield indicates that Germany's borrowing costs at this maturity showed no significant change compared with the prior auction.

Meanwhile, the bid-to-cover ratio, a key measure of investor demand, declined from 1.6 to 1.4. The decrease suggests weaker demand for long-term German government bonds. Softer investor appetite could become an important factor in assessing Germany's future borrowing costs and the outlook for European bond markets.
