Shot across the Bow--Fitch Keeps U.S. Credit Rating at ‘AAA’, Cuts Outlook to Negative 

 Fitch Ratings kept its pristine AAA rating on the U.S. on Monday, but the credit-ratings company downgraded its outlook to “negative” in the wake of the Supercommittee’s failure to find $1.2 trillion in spending cuts.

The development, which had been hinted at last week, could have been worse for the U.S. as McGraw-Hill’s (MHP: 41.20, +0.66, +1.63%) Standard & Poor’s slashed its credit rating for the first time ever in August.

However, the negative outlook indicates a “slightly greater” than 50% chance that Fitch downgrades the U.S. over the next two years.

“Failure to reach agreement in 2013 on a credible deficit reduction plan and a worsening of the economic and fiscal outlook would likely result in a downgrade of the U.S. sovereign rating,” David Riley, a managing director at Fitch, said in the report.

Fitch warned that its revised fiscal projections call for federal debt held by the public to exceed 90% of gross domestic product and debt interest payments making up more than 20% of total tax revenues by the end of the decade.
