OH DAMN Standard & Poor's is examining the credit rating of all 17 euro zone countries for a possible downgrade â not just the top six â as the continent's debt crisis lingers, a person familiar with the matter said. S&P is likely to make an announcement on putting the euro countries on "credit watch" after the closing of markets in the U.S. on Monday, the person said. The person was speaking on condition of anonymity because of the sensitivity of the matter. The threat to downgrade all 17 euro zone countries â including the ones that enjoy the stellar triple-A-rating â comes ahead of a crucial summit of EU leaders later this week. Earlier, the Financial Times had reported that the ratings agency warned Germany, France, the Netherlands, Austria, Finland and Luxembourg that the countries' top-notch ratings could be downgraded to double-A plus. http://www.cnbc.com/id/45557844
