In this research update, Standard & Poor's†explains their rationale behind lowering†the long-term sovereign credit rating on the United States of America to 'AA+' from 'AAA' and affirming the 'A-1+' short-term rating.
We lowered our long-term rating on the U.S. because we believe that the prolonged controversy over raising the statutory debt ceiling and the related fiscal policy debate indicate that further near-term progress containing the growth in public spending, especially on entitlements, or on reaching an agreement on raising revenues is less likely than we previously assumed andwill remain a contentious and fitful process. We also believe that the fiscal consolidation plan that Congress and the Administration agreed to this week falls short of the amount that we believe is necessary to stabilize the general government debt burden by the middle of the decade.
Our lowering of the rating was prompted by our view on the rising public debt burden and our perception of greater policymaking uncertainty, consistent with our criteria (see "Sovereign Government Rating Methodology and Assumptions," June 30, 2011, especially Paragraphs 36-41). Nevertheless, we view the U.S. federal government's other economic, external, and monetary credit attributes, which form the basis for the sovereign rating, as broadly unchanged.
We have taken the ratings off CreditWatch because the Aug. 2 passage of the Budget Control Act Amendment of 2011 has removed any perceived immediate threat of payment default posed by delays to raising the government's debt ceiling. In addition, we believe that the act provides sufficient clarity to allow us to evaluate the likely course of U.S. fiscal policy for the next few years.
