The Monetary Authority's Yam revised interbanktrading rules to boost liquidity in the banking system, making it harder to manipulate local-dollar interest rates.
The yuan started trading against the ruble in the Chinese bank market in Shanghai last November, and in December, began trading on the Moscow Interbank Currency Exchange.
The Moscow Exchange was created in 2011 from the merger of the Moscow Interbank Currency Exchange and the Russian Trading System, and only adopted its current name last year.
