1. Although Eurodollar is a kind of US dollar and has the function of US dollar, Eurodollar is not regulated by the Federal Reserve, but by its holders. Eurodollar is actually a general term, which refers to dollars deposited in banks outside the United States and not regulated by the US Federal Reserve system. China is the largest holder of Eurodollars (that is, the origin of folk saying that China is the largest creditor of the United States). So to sum up, Eurodollar belongs to foreign exchange for the United States, both conceptually and practically.

2. The number must belong to: (1) a bank with savings outside the United States. (2) Not subject to the supervision of the US Federal Reserve system. (3) The currency belongs to the US dollar.

3, does not belong. This is a kind of foreign exchange reserves, that is, foreign exchange assets held by central banks and other government agencies to meet the needs of international payment.

Simply put, if China doesn't hold Eurodollars, then everything China buys in the United States should be settled at the exchange rate at that time, so it is difficult to protect its own interests, and it is likely that "more money will buy less things". However, if China holds Eurodollars, it can use its own "own dollars" to settle accounts, and the protection of interests is more secure than the former.

But now it seems that there are too many euros and dollars in China, which is probably dominated by the US government in today's background. (The result may be that China's Eurodollars are hoarded at home, increasing their holdings, and Americans take the opportunity to make a fortune. )
