 According to a stress test conducted by the central bank Russian financial system would be able to handle a currency decline of 25%–30% without major central bank interference.However, the Russian economy began stagnating in late 2013 and in combination with the War in Donbass is in danger of entering stagflation, slow growth and high inflation.The recent decline in the Russian ruble has increased the costs for Russian companies to make interest payments on debt issued in U.S. dollar or other foreign currencies that have strengthened against the ruble; thus it costs Russian companies more of their ruble-denominated revenue to repay their debt holders in dollars or other foreign currencies.
