MADRID (MarketWatch) -- Moody's Investor Service said Wednesday it has put Spain's Aa1 rating on review for a possible downgrade. Among the main triggers for the downgrade are Spain's vulnerability to funding stress given its high refinancing needs in 2011, which has been "recently amplified by fragile market confidence." Another trigger is a potential further rise in the public debt ratio should the cost of bank recapitalisation prove to be higher than expected so far. Finally, Moody's cited "increased concerns" of the ability of the Spanish government to achieve required sustainable and structural improvement in government finances, given its limited ability to control regional government finances. Moody's has also placed the Aa1 rating of Spain's Fondo de ReestructuraciÃ³n Ordenada Bancaria (FROB) on review for possible downgrade as its debt is fully and unconditionally guaranteed by the government of Spain. Moody's said it continues to view Spain as a "much stronger credit than other stressed euro zone countris," and that its review will most likely conclude that Spain's rating will remain in the Aa range. http://www.marketwatch.com/story/moodys-puts-spain-on-review-for-downgrade-2010-12-15 MoodyÂ´s rating is as worthless as toxic CDO sh1t.
