Russia warns could 'reduce to zero' economic dependency on US
Russia could reduce to zero its economic dependency on the United States if Washington agreed sanctions against Moscow over Ukraine, a Kremlin aide said on Tuesday, warning that the American financial system faced a "crash" if this happened.
"We would find a way not just to reduce our dependency on the United States to zero but to emerge from those sanctions with great benefits for ourselves," said Kremlin economic aide Sergei Glazyev.
He told the RIA Novosti news agency Russia could stop using dollars for international transactions and create its own payment system using its "wonderful trade and economic relations with our partners in the East and South."
Russian firms and banks would also not return loans from American financial institutions, he said.
"An attempt to announce sanctions would end in a crash for the financial system of the United States, which would cause the end of the domination of the United States in the global financial system," he added.

So Russia is going to abandon the dollar as a reserve currency? Good luck with that one – Telegraph Blogs
I've written before about the inevitability of decline for the dollar as the world's major reserve currency, but this process is on a very long fuse and basically depends on China eventually displacing the US as the world's largest economy.
That's not going to happen any time soon. In the meantime, the dollar remains overwhelmingly the currency of choice for international transactions, and is the middle currency in virtually all transactions. For instance, if you were looking to buy Singapore dollars with Russian roubles, you would typically first buy US dollars with your roubles and then swap them into Singapore dollars. The US dollar is also the pricing currency for virtually all commodity transactions, including crucially, oil. Repeated attempts to set up alternative pricing arrangements have all come to nothing.
Then finally, more than 60 per cent of the world's central bank foreign currency reserves are held in dollars. The euro, the next biggest reserve currency, comes nowhere close. This is not about to change. In other words, Russian threats are as vacuous as Western ones. Hey ho.
