US dollar is not only the base currency in foreign exchange, but also the main currency in international payment and foreign exchange transaction. It plays a very important role in the international foreign exchange market. Although the U.S. dollar has received a certain impact since the 2008 financial crisis, its international status is still very strong. The US dollar is still the basic currency in the world. It is also a major currency in international payments and foreign exchange transactions. If it can be directly linked with gold, its international status is still leading no matter how.
At its peak, more than 90% of Global trade was settled in US dollars. Now, although the system of direct exchange of US dollar into gold has been abolished and the status of US dollar has been challenged to a certain extent due to economic globalization, the status of US dollar in the world is still very important. At present, no country has more currency status than the US dollar, and the foreign exchange reserves of many countries are still US dollars.
