NEW YORK (CNNMoney) -- Standard & Poor's lowered its outlook for the nation's long-term debt Monday, even as it reaffirmed the agency's top-tier rating for the U.S. economy.

S&P maintained its 'AAA/A-1+' credit rating on U.S. sovereign debt, saying the nation's "highly diversified" economy and "effective monetary policies" have helped support growth.
