BlockBeats News, Oct. 7: U.S. Democratic Senator Elizabeth Warren sent a series of questions to Treasury Secretary Scott Bessent regarding the Treasury Department’s recent “unprecedented and chaotic” interventions in the U.S. Treasury market. Warren asked Bessent to explain how the Treasury plans to fund Treasury buybacks by reducing its cash balance, and what steps it will take to lower long-term U.S. Treasury yields. She also asked whether the Treasury had assessed the impact of rising long-term Treasury yields on consumer borrowing costs, including auto loans and mortgage rates.
