All three major U.S. stock market indexes rose Monday afternoon, following an earlier selloff sparked by long-dated Treasury yields surpassing the 5% mark after the financial ratings agency Moody’s downgraded the U.S. government’s credit rating late last week, citing rising debt and interest payment ratios.

Moody’s cut the U.S.’s sovereign credit rating from Aa1 to Aaa. It was the last of the major credit-rating firms to strip the country of its triple-A rating. S&P Global Ratings downgraded U.S. debt in the summer of 2011.
