| The 
				rouble has firmed about 30% against the dollar this year despite 
				a full-scale economic crisis in Russia, making it the world's .
 The rouble is steered by capital controls imposed in late 
				February to shield Russia's financial sector after Moscow's 
				decision to send tens of thousands of troops into Ukraine 
				prompted unprecedented Western sanctions.
 
 At 1110 GMT, the rouble was 2.5% stronger against the dollar at 
				56.36, hovering around this level for the first time in more 
				than four years.
 
 Against the euro, the rouble gained 3% to 58.24, its strongest 
				in seven years.
 
 "The rouble's sharp gains again owed to tomorrow's looming 
				deadline for 600 billion roubles ($10.43 billion) in mineral 
				extraction tax payments and the conversion of payment for gas 
				exports into roubles," Sberbank CIB said in a note.
 
 "We think the local currency may have trouble prolonging its 
				recent rally, as selling activity among exporters may begin to 
				decline."
 
 The currency's strength has raised concerns about the negative 
				impact on Russia's budget revenue from exports. On Monday, 
				Russia cut the proportion of foreign currency revenue that 
				exporters must convert into roubles to 50% from 80%.
 
 Despite the slight relaxation in capital controls, the rouble 
				could firm to 55 against the dollar in the near term, said 
				Dmitry Polevoy, head of investment at LockoInvest.
 
 "Current levels could be used to open long positions in foreign 
				currencies by mid- and long-term investors," Polevoy said.
 
 The rouble may return to levels of 60-65 against the dollar in 
				June, Sinara Investment Bank said in a note.
 
 The rouble was weaker at banks. Russia's largest lender Sberbank 
				offered to sell cash dollars and euros for 58.20 and 60.38 
				roubles, respectively.
 
 Russian stock indexes were mixed.
 
 The dollar-denominated RTS index reversed earlier losses and 
				gains 1% to 1,267.1 points. The rouble-based MOEX Russian index 
				was 1.6% lower at 2,265.5 points, pressured by the rouble gains.
