Do Treasury buybacks lower long-term yields despite ongoing deficits?
Core argument: Treasuries have outperformed equivalent-maturity swaps since Bessent's announcement, narrowing the 30-year swap spread to its smallest since February, with the 10-year swap spread three basis points smaller at around 38 basis points.
Since Bessent’s announcement, Treasuries have outperformed equivalent-maturity swaps, narrowing the 30-year spread to the smallest since February. Swaps are popular with some investors as an alternative to owning bonds; the gap between [swap rates] and US government yields [gauges] how willing [investors] are to hold Treasuries instead. The 10-year swap spread has compressed too, with the gap three basis points smaller at around 38 basis points. Still, the recent drop has only dented a years-long rise in long-term US government borrowing costs. The 10-year US yield inched up 3bp to 4.66% after touching 4.75% last week. “While conducting buybacks at the long end of the yield curve may technically decrease yields, higher structural US budget deficits, which [require] a significant supply of Treasuries to finance the US debt, [are] not changing anytime soon,” said Libby Cantrill, head of public policy at Pimco.
