Fitch Places United States' 'AAA' on Rating Watch Negative

Fitch Ratings-New York/London-15 October 2013: Fitch Ratings has placed the United States of America's (U.S.) 'AAA' Long-term foreign and local currency Issuer Default Ratings (IDRs) on Rating Watch Negative (RWN). The ratings of all outstanding U.S. sovereign debt securities have also been placed on RWN, as has the U.S. Short-term foreign currency rating of 'F1+'. The Outlook on the Long-term ratings was previously Negative. The U.S. Country Ceiling has been affirmed at 'AAA'.
Fitch expects to resolve the RWN by the end of Q114 at the latest, although timing would necessarily reflect developments and events, including the duration of any agreement to raise the debt ceiling.
KEY RATING DRIVERS
In line with Fitch's previous statements, the RWN reflects the following key rating drivers and their relative weights:
High
- The U.S. authorities have not raised the federal debt ceiling in a timely manner before the Treasury exhausts extraordinary measures. The U.S. Treasury Secretary has said that extraordinary measures will be exhausted by 17 October, leaving cash reserves of just USD30bn. Although Fitch continues to believe that the debt ceiling will be raised soon, the political brinkmanship and reduced financing flexibility could increase the risk of a U.S. default.
- Although the Treasury would still have limited capacity to make payments after 17 October it would be exposed to volatile revenue and expenditure flows. The Treasury may be unable to prioritise debt service, and it is unclear whether it even has the legal authority to do so. The U.S. risks being forced to incur widespread delays of payments to suppliers and employees, as well as social security payments to citizens - all of which would damage the perception of U.S. sovereign creditworthiness and the economy.
- The prolonged negotiations over raising the debt ceiling (following the episode in August 2011) risks undermining confidence in the role of the U.S. dollar as the preeminent global reserve currency, by casting doubt over the full faith and credit of the U.S. This "faith" is a key reason why the U.S. 'AAA' rating can tolerate a substantially higher level of public debt than other 'AAA' sovereigns.
