In a move that sent jitters to global markets, Standard & Poor's cut US rating to AA+ from triple-A late last week. "The political system in US is not as strong as earlier. Also, the government there proactively failed to take measures on the economy. A debate on US debt cap exposed weakening US political system," the rating agency said.
Moody's repeated a warning on Monday it could cut the US rating before 2013 if the fiscal or economic outlook weakens significantly but said it saw the potential for a new debt agreement in Washington to cut the budget deficit before then.
Laurence Balanco of CLSA said the Nifty has slipped below its key support area that was running from 5100 to 5200.
The United States took a step closer to losing its coveted triple-A credit rating over the weekend as a political impasse in Washington reduced hopes of an agreement to meaningfully cut the nation's budget deficit.
