The U.S. is set to hit its debt ceiling on Tuesday, which has initiated a countdown for Congress to address the situation. Treasury Secretary Janet Yellen has warned that extraordinary measures will be implemented to avert a default as the country approaches its $36 trillion debt limit. These actions are crucial, especially with the upcoming transition of presidential office. The Treasury plans to suspend investments in government employee benefit funds and take other steps to ensure financial stability. Despite these efforts, the pressure is mounting on Congress to find a long-term solution to these looming fiscal challenges.
