Moody's downgrades United States credit rating outlook

"Moody's Investors Service (Moody's) has changed the outlook on the ratings of the U.S. government to negative from stable and affirmed the long-term issuer and senior unsecured ratings at 'Aaa'," the company said in a press release.

According to reports, the key reason for changing the forecast for the worse was the potential hazards of diminishing the United States' fiscal sustainability. Moody's notes that they can no longer be offset by the country's unique credit advantages. 

"In an environment of rising interest rates without effective fiscal policy measures to reduce government spending or increase revenues, Moody's expects the US budget deficit to remain very large," the rating agency stated.
