At 0855 GMT, the rouble was 0.15% stronger against the dollar at 63.93 and gained 0.14% to 71.60 versus the euro.

The rouble firmed 0.6% on Tuesday, touching 63.91 to the dollar, its highest since April 24 after the ministry said it would auction two series of OFZ treasury bonds.

The auction was not held last week because of a public holiday. Demand for treasury bonds, which serve as a gauge of investor interest in Russian assets, has supported the rouble this year.

Brent crude oil, a global benchmark for Russia's main export, was up 0.3% at $62.30 a barrel.

Russian stock indexes were up. The dollar-denominated RTS index rose 0.40% to 1,364 points. The rouble-based MOEX Russian index was 0.31% higher at 2,770 points.
