The U.S. has reached its $31.4t debt ceiling, the Treasury Department announced on Thursday, with no obvious deal in sight. Treasury Secretary Janet Yellen in a letter to Congress said that Treasury was instituting a "debt issuance suspension period" beginning Thursday and running through June 5. In addition, Treasury will not be able to fulfill certain investments, including to the Civil Service Retirement and Disability Fund.
"As I stated in my January 13 letter, the period of time that extraordinary measures may last is subject to considerable uncertainty, including the challenges of forecasting the payments and receipts of the U.S. government months into the future," Yellen stated.
