As of Oct. 24, the ruble's new floating corridor extended from 38.05 to 47.05 against a dollar-euro basket, compared with 37.70 to 46.70 previously.
The Central Bank also said Monday that it had conducted 113.64 billion rubles' ($2.72 billion) worth of forex interventions to defend the ruble on Oct. 23.
