Only Greece (whose rating was already at CC categorized as "highly vulnerable, speculative bonds" with a high near-term probability of default) and Cyprus (whose rating was already on review) escaped this ratings action. S&P explained that these "CreditWatch placements are prompted by our belief thatsystemic stresses in the euro zone have risen in recent weeks to the extent that they now put downward pressure on the credit standing of the euro zone as a whole." France is the country which is facing the most severe warning, with S&P saying Europe's second largest economy could be downgraded two notches unless it improves its budgetary position. France's finance minister Francois Baroin is reported by Reuters to have already ruled out more cuts. He argues that S&P has not taken account of yesterday's agreement between Sarkozy and Chancellor Angela Merkel of Germany to centralise Eurozone budget planning.
