[U.S. Treasury Secretary: High interest rates put U.S. debt to the test] Golden Finance reported that U.S. Treasury Secretary Yellen said that the prospect of interest rates remaining at a high level in the long run makes it more difficult to control U.S. borrowing needs, highlighting the importance of focusing on increasing fiscal revenue in budget negotiations with Republican lawmakers. "We have raised our interest rate expectations, and that does have an impact," Yellen said. "It makes it more challenging to keep deficits and interest payments under control." She reiterated, emphasizing the ratio of inflation-adjusted interest payments to GDP. This ratio has risen over the past year, but the White House expects it to stabilize at around 1.3% over the next decade. "I don't have a hard and fast rule, but I don't want to see it above 2%," she said. This is her most explicit comment on this indicator so far.
