Trading on Moscow Exchange's stock and derivatives sections will remain close on Tuesday, the Russian central bank said on Monday, extending the suspension of trading amid a full-blown financial crisis triggered by Western sanctions.

The central bank said it will inform about future Moscow Exchange operations before 0600 GMT on Wednesday.

The rouble tumbled to a record low in extremely volatile trade on Monday, losing a third of its value so far this year, while Moscow's stock market was closed the entire day.
