Suffering from U.S. and EU sanctions, Russia made a surprise moveits central bank fixed the price of 5,000 rubles to a gram of gold. Few Western investors or executives noticed. Then, Russia ... announced that it would require payment for oil, natural gas and other of its significant exports in rubles. "What the Russians did was a genius," explains Jack Bouroudjian, former president of Commerce Bank in Chicago. "It forces people to go to the Russian central bank and pay gold to get rubles to make the transactions." The ruble had been trading in the range of 70 to 80 for a U.S. dollar. After the sanctions, it plummeted to 120. "Now the ruble basically recovered, trading 80 rubles to the dollar. And it's because of the way they pegged the ruble to gold." U.S. companies that have either international suppliers or customers could be jolted by Russia's golden move. Overseas business partners may need to barter gold for rubles to pay for inputs, like energy, minerals or fertilizers, and therefore demand that their U.S. counterparts pay in rubles or bullion. Additionally, American firms may need to acquire a stack of rubles to pay for their own inputs for foreign-based factories, warehouses or raw materials. Russia isn't alone in its desire. "China has been explicit" in its desire to displace the dollar and make the yuan more central. China is taking preliminary measures to defend their state-owned assets against financial sanctions similar to those the U.S. launched against Russia.
