Long-dated Treasuries rallied with the 30-year bond jumping more than 3 points

The cost to insure against $10 million of debt issued by the U.S. government jumped to 47.5 basis points or $47,500 per year for five years, according to credit data company CMA DataVision. This compared with 43.5 basis points or $43,500 late Monday.

Earlier, before these latest expenditures, CNBC wrote a story that the U.S. might lose it's AAA credit rating.

The United States may be on course to lose its 'AAA' rating due to the large amount of debt it has accumulated, according to Martin Hennecke, senior manager of private clients at Tyche.

"The U.S. might really have to look at a default on the bankruptcy reorganization of the present financial system" and the bankruptcy of the government is not out of the realm of possibility, Hennecke said.

Naked Capitalism has a good overview post from earlier this month (which doesn't include these latest jumps).
