Treasury debt buybacks fail to curb surging yields

Goldman Sachs analysts believe that changing the type of debt governments issue will not significantly lower long-term yields, as the fundamental need for borrowing remains unchanged. The investment bank attributes the rise in yields to persistent fiscal deficits across developed economies, resilient economic data, and increased borrowing for AI investments, which they estimate could account for about 1% of global GDP.

George Cole, head of European rates strategy at Goldman Sachs, noted that the recent climb in yields has been orderly, making it difficult to argue the bond market is fundamentally mispriced. While Goldman Sachs anticipates that energy-driven inflation concerns may fade in the coming months and greater clarity on AI returns could ease some borrowing pressures, fiscal concerns are expected to persist. The firm sees little evidence that changes in debt issuance alone can materially lower long-term yields, expecting investors to continue demanding higher returns.
