Germany has sold long-dated bonds at their highest yield in 15 years, reflecting growing investor unease over rising government debt and persistent inflation. According to sources who requested anonymity, the German Finance Agency issued €4 billion ($4.6 billion) of bonds maturing in August 2056 via a syndicated sale, with a yield of 3.783%.

Orders for the sale exceeded €38 billion, broadly in line with recent issuance transactions. Last month, Germany auctioned a smaller 30-year bond at a yield of 3.64%, the highest for a regular auction of this tenor since 2011. However, further weakness in global bond markets over recent weeks has pushed German yields to levels not seen since the eurozone debt crisis era.

Where the market stands now

In a report last month, Commerzbank rate strategist Hauke Siemssen highlighted that Germany's financing needs are projected to climb significantly by 2027, with the draft budget showing net borrowing requirements of €204 billion. He expects net issuance of German federal bonds to reach a record €163 billion next year, up from approximately €137 billion in 2026. Total issuance is also anticipated to rise to around €400 billion, marking an all-time high.

The elevated yield levels underscore the tension between fiscal expansion and investor demands for higher compensation, a dynamic likely to persist as supply pressures intensify. With the government's borrowing pipeline expanding, market participants will be watching closely for any signs of strain in absorption capacity, particularly as central bank balance sheet reduction continues to remove a key source of demand.
