The report from the People's Bank of China (PBOC) said a "super-sovereign" currency should take its place.

Central bank chief Zhou Xiaochuan has loudly led calls for the dollar to be replaced during the financial crisis.

"An international monetary system dominated by a single sovereign currency has intensified the concentration of risk and the spread of the crisis," the Chinese central bank said.

The dollar fell after the report was released. The US currency dropped 1% against the euro to $1.4088, and declined 0.8% versus the British pound to $1.6848.

"To avoid intrinsic shortcomings in using a sovereign currency as a reserve currency, we need to create an international reserve currency that is divorced from sovereign states and can maintain a stable value over the long term," the PBOC report said.
