According to analysts of the international rating agency Moody's Investors Service, the U.S. and Britain came close to the loss of their credit ratings to the highest level "AAA" in the coming years, due to a significant increase in the cost of servicing their debts. And for 2012-2013, the U.S. will become the world leader for the cost of servicing the public debt. This year, the U.S. government will spend just under 7% of State Revenue for debt service, and in 2013 - already 11%, if one adheres to a conservative forecast. On worst-case U.S. spends 15% of revenues for debt service, which will lead to a lowering of credit rating to 'AA' (for a higher credit rating of the maximum cost of servicing government debt does not exceed 14% of government spending). In monetary terms, the size of the U.S. national debt in the current year reached 14.456 billion dollars - that is, about 98.1% of GDP. Britain spends on debt service 7% of revenues in 2010 and 9% - in 2013 the most likely scenario. According to the managing director of sovereign risk, Moody's Pierre Kaito, governments of these countries should as soon as possible to reduce the debt burden, while maintaining economic growth.
