This is Moody's saying this:
Ratings agency Moody's on Monday suggested the United States should eliminate its statutory limit on government debt to reduce uncertainty among bond holders.The United States is one of the few countries where Congress sets a ceiling on government debt, which creates "periodic uncertainty" over the government's ability to meet its obligations, Moody's said in a report.
"We would reduce our assessment of event risk if the government changed its framework for managing government debt to lessen or eliminate that uncertainty," Moody's analyst Steven Hess wrote in the report.
