Russia's finance ministry said on Tuesday it would buy foreign currency totalling 9.7 billion roubles ($147.90 million) between Feb. 7 and March 6, scaling down daily purchases from 15.6 billion roubles in the previous period.
"This factor won't have a visible impact on the Russian currency market that will continue trading taking into external markets' attitude towards risky assets," Nordea Bank analysts said in a note.
Daily foreign currency purchases that the central bank carries out on the market on behalf of the finance ministry limit the room for the rouble's appreciation.
The finance ministry also announced details of its weekly auctions due on Wednesday where it sells OFZ treasury bonds. Demand for such bonds is seen as a gauge of investors' attitude towards Russian assets.
