MOSCOW: The rouble weakened past 59 against the dollar on Tuesday and slumped against the euro, giving up most of the previous session’s gains, as concerns over possible new sanctions against Moscow continued to buffet the Russian currency.

The rouble has experienced significant swings in recent sessions, hampered by limited liquidity and investors’ concerns that any new sanctions over Russia’s actions in Ukraine could restrict access to foreign currency in Moscow.

By 1509 GMT, the rouble was 0.6% weaker against the dollar at 59.23? and had lost 5.3% to trade at 56.42 versus the euro. It had firmed 0.2% against the yuan to 8.25.
