Rating agencies also provide outlook for the countries. Outlook provided by the rating agencies assesses the potential direction in which a rating will move over the next six months to two years.
Positive - may be raised
Negative - may be lowered
Stable - unlikely to change
Developing - may be raised or lowered
NM - not meaningful
Lowering an outlook is generally considered to be the first step towards a downgrade.
For instance, Credit rating agency Moody's still has maintained AAA credit rating for U.S. for the time being but lowered its outlook on U.S. debt to "negative."
A "negative outlook" indicates the possibility that Moody's would downgrade the country's sovereign credit rating within a year or two.
