USD history.

in p>1792, the U.S. dollar formed a currency area in 13 colonies. At that time, the United States was only a country with 4 million people. By the end of 19th century, it had become the most powerful country in the world. By the time the First World War broke out in 1914, the total economic output of the United States was larger than that of the other three largest countries: Britain, Germany, France, and even the sum of them, which made the dollar's position increasingly prominent.

During World War I, gold from European countries flowed into the United States to buy war supplies. The United States Federal Reserve Bank used these gold as legal tender, which led to inflation. From 1914 to 192, 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 a period of deflation. In 192, the price level dropped from 2 to 14, a drop of 3%, 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 security of international trade and credit, facilitating the accounting of production costs and avoiding the risks of international investment.
