"The U.S. dollar is on our minds these days because it is weak and getting weaker. We hear reports that Chinese officials are actively cautioning, scolding and remonstrating the U.S. on its profligate ways because China has an estimated $2 trillion+ in reserves, much of it invested in dollar-denominated securities.China’s financial reserves are big enough that the Chinese government has to have its foreign assets denominated in a very large, liquid currency. And, there are not too many of those around other than the U.S. dollar, the Euro and the Yen. For a variety of historical and cultural reasons, one can doubt if the Chinese would seriously entertain putting most of their foreign currency and foreign assets holdings in the Japanese Yen, so the currency choice is between the dollar and the Euro".
