From the Wall Street Journal:
Moody’s said the U.S., Germany, France and the U.K. still have debt metrics, including the debt affordability, compatible with their triple-A ratings at Moody’s. But all four countries must bring the future costs arising from pension and healthcare subsidies under control if they “are to maintain long-term stability in their debt burden credit metrics,” Moody’s said in its regular triple-A Sovereign Monitor report.
Moody’s noted that measures were recommended by the U.S. National Commission on Fiscal Responsibility and Reform, appointed by President Obama, to achieve a balanced primary budget by 2015, but that there was insufficient support to trigger consideration of those recommendations by the full Congress.
