Are countries trying to end US dollar's power?

Russia has suggested the U.S. dollar could lose its status as the global trading currency. The U.S. has put sanctions on Iran, Turkey and Russia, so these countries could start doing business in their own currencies instead. Countries that have had trade tariffs put on them by the U.S. could do the same. China is already doing trade deals in its own currency the yuan. The dollar could lose its role as the international reserve currency.

The U.S. dollar became the international reserve currency in the 1920s. Most global trade takes place using it. If China buys oil from Iran, it pays in dollars. This means billions of dollars flow out of the USA and gives the USA a currency deficit. Russia said: "The grave abuse of the role of the U.S. dollar as a global reserve currency will result…in the…demise of its role." China's currency is emerging as a new trading currency. Nigeria has already started using it.
