NEW YORK--(BUSINESS WIRE)--Fitch Ratings has affirmed at 'AAAsf' 53 rated U.S. RMBS classes with credit ratings linked to the U.S. Sovereign rating. On March 21, 2014, Fitch affirmed the U.S. Sovereign rating at 'AAA' rating with a Stable Outlook.
A spreadsheet listing the classes can be found on Fitch's web site at 'www.fitchratings.com' by performing a title search for 'U.S.-Linked RMBS Classes March 25, 2014'.
KEY RATING DRIVERS
The 'AAAsf' credit rating of the affected RMBS classes relies on guarantees provided by the government-sponsored enterprises, Fannie Mae and Freddie Mac. Additionally, one class is collateralized with U.S. Treasury Notes. Although most classes also generally benefit from additional forms of credit enhancement (such as subordination), the credit enhancement alone would not be sufficient to maintain an 'AAAsf' credit rating on the RMBS classes if the U.S. Sovereign rating was downgraded below 'AAA'.
Fitch did not conduct loan-level loss analysis or cash flow analysis in its rating review for these classes. The ratings are determined by the U.S. Sovereign rating.
The ratings of these RMBS will be dependent on the U.S. Sovereign rating. The current rating Outlook is Stable. Consequently, Fitch's sensitivity analysis does not currently anticipate developments with a material likelihood, individually or collectively, of leading to a rating downgrade. However, future developments that may, individually or collectively, lead to negative rating action include:
--A significant increase in general government deficits and debt/GDP ratio; for example, if the U.S. authorities do not take measures in the medium term to offset rising expenditure pressures from ageing and higher interest rates later in the decade.
--A material deterioration in the coherence and credibility of economic policymaking or a negative shock that erodes the role of the U.S. dollar as the pre-eminent global reserve currency and reduces financing flexibility and debt tolerance.
