The dollar world accounts for 59%. Specifically, the share of the US dollar in foreign exchange reserves is 59%, which has declined for three consecutive quarters. In contrast, during the period from 1977 to 199 1, the proportion of US dollar assets in global foreign exchange reserves was as high as 85%, but now it has dropped by about 30%.

The history of the dollar:

1 and 1792, the US dollar formed a currency area in the colony of 13. At that time, the United States was only a country with a population of 4 million. By the end of 19, it has become the most powerful country in the world. By the time World War I broke out in 19 14, the total economic output of the United States was already greater than that of the three largest countries: Britain, Germany, France, and even the sum of them, which made the status of the US dollar increasingly prominent. During World War I, gold from European countries flowed into the United States to buy war materials. The Federal Reserve Bank of the United States used these gold as legal tender, which led to inflation. From 19 14 to 1920, the price level in the United States nearly doubled. Later, the Federal Reserve Bank of the United States decided to control inflation and tried to restore the price to its original level. Then came the period of deflation, when the price level dropped from 200 to 1920 in one year, which was the biggest deflation in American history. Although the 35 years of the gold standard system is the "golden age" for the prosperity of liberal capitalism, the fixed exchange rate system has the advantages of ensuring the safety of international trade and credit, facilitating the accounting of production costs and avoiding international investment risks. To some extent, it has promoted the development of international trade and investment. However, the strict fixed exchange rate system makes it difficult for countries to implement favorable monetary policies according to their own economic development needs, which greatly restricts economic growth. During World War II, the international monetary system became more chaotic. In order to solve this chaotic situation, 1943, US Treasury official White and British Treasury consultant Keynes designed the post-war international monetary and financial system from their own interests, and put forward two different schemes, namely "White Scheme" and "Keynes Scheme".

2. The "White Plan" advocates the abolition of foreign exchange control and restrictions on international capital transfer in various countries, the establishment of an international stability fund, and the issuance of the international currency "UNITA" to keep the currencies of various countries at a fixed price, that is, the fund currency is linked to the US dollar and gold. The currencies of member countries should maintain a fixed parity with UNITA, and the currencies of member countries should not depreciate without the approval of three-quarters of the voting rights of IMF member countries. Based on the shortage of gold reserves in Britain at that time, the "Keynesian Plan" advocated the establishment of a world central bank to transfer the creditor's rights and debts of various countries through its deposit accounts for liquidation.
