President Donald Trump said he had not instructed Treasury Secretary Scott Bessent to intervene in the US bond market and argued that economic growth could resolve the national debt problem. The remarks came after the Treasury Department announced it would at least double liquidity-support buybacks for 10- to 30-year Treasuries, lifting each operation to at least $4 billion, while the 30-year yield rebounded to around 5.26%. Bessent said the Treasury had a "big toolbox" and could increase buybacks further, but the market remained skeptical that such operations could solve the long-term debt supply-demand imbalance. Bessent also said Trump had tasked him and the director of the US Office of Management and Budget with leading a fiscal consolidation plan, expected this weekend or early next week. On Iran, Trump combined continued pressure with the possibility of negotiations, while Bessent pledged "unprecedented economic isolation" and previewed an August 24 press conference on the US action plan. Oil prices are a key risk for inflation and long-term Treasury yields. Trump also said US-Canada trade talks were "progressing well," that the US should be able to reach a deal with Canada and that a new agreement had been initiated with Mexico.
