A publicity-minded Chinese rating agency has added its two renminbi to the cacophonous debate over the Fed's latest tilt at money-printing. The state-backed Dagong Global Credit Rating Co. on Tuesday downgraded its rating on the United States to A-plus from double-A, maintaining its negative outlook.

"The new round of quantitative easing monetary policy adopted by the Federal Reserve has brought about an obvious trend of depreciation of the U.S. dollar, and the continuation and deepening of credit crisis in the U.S.," Dagong writes in its latest report on its U.S. rating. "Such a move entirely encroaches on the interests of the creditors, indicating the decline of the U.S. government's intention of debt repayment."

But Dagong is willing to go where many observers have been unwilling to tread, contending that the collapse of the dollar is near. "Analysis shows that the crisis confronting the U.S. cannot be ultimately resolved through currency depreciation," it writes. "On the contrary, it is likely that an overall crisis might be triggered by the U.S. government's policy to continuously depreciate the U.S. dollar against the will of creditors."
