“An international monetary system dominated by a single sovereign sovereign currency has intensified the concentration of risk and the spread of the crisis.” — People’s Bank of China (2009)
It should go without saying that China and Russia have designs to end the U.S. Dollar hegemony free ride. This is fundamental to understand and will be a game changer. The impacts on the standard of living of these players will be profound and especially negative for the U.S. How and in what manner this plays out is the question. I strongly believe that the answer lies in two parts: letting the U.S. put a noose around its own neck and then at the appropriate time, kicking the chair out from under it.
