The Treasury plans to auction $16 billion of 20-year bonds, with results due just after 1 p.m. Eastern. The offering will mark the first auction of longer-duration Treasury bonds since Moody’s on Friday became the third and final rating agency to strip the U.S. of its top Triple-A credit rating.

Moody’s decision to join other major ratings agencies in downgrading the U.S.’s once-pristine credit rating could have a tangible impact on Americans’ wallets. The agency has dropped the U.S. sovereign credit rating—an assessment of the country’s ability to pay its debts—down one level from the highest possible Aaa to Aa1.
