The earliest monetary system in history is the silver standard system, which is based on silver. China officially adopted the silver standard on 10 10 and abolished it on 1935.
Internationally, the monetary system that emerged after the silver standard system in various countries is the gold standard system, which is a real international monetary system. The gold standard refers to the monetary system based on gold. Simply put, there is a fixed exchange ratio between the currency and gold in each country, that is, how much gold is issued in this country.
Gold standard countries can't issue money at will, so this system has curbed hyperinflation; Secondly, the currencies and exchange rates of countries are fixed, which is beneficial to international trade. For example, in the United States, $30 equals an ounce of gold, while in Britain, $5 equals an ounce of gold. The exchange rate between the dollar and the pound is 1, which is 6 dollars.
