By 0923 GMT, the rouble was 1% stronger against the dollar at 78.44 , its strongest mark since April 3.

It gained 1.1% to trade at 86.74 versus the euro and was 1.1% firmer against the yuan at 11.33 , also its strongest since early April against both currencies.

The rouble strengthened sharply after the central bank held interest rates steady on Friday, but retained the prospect of future hikes. The rouble has also benefited with a lag from high oil prices throughout April, which translates to higher export revenues for Russian exporters.

But after month-end taxes were paid on April 28, the rouble can now count on reduced supply of foreign currency in the market.

Brent crude oil, a global benchmark for Russia's main export, was up 1.2% at $73.19 a barrel.

The drop in oil prices to $73 from $80 per barrel will put pressure on the rouble and may lead to another wave of weakening, said Banki.ru chief analyst Bogdan Zvarich in a note.

"In the current situation, risks remain that the dollar-rouble pair will return to the 80-82.5 range," Zvarich said.

Oil prices were recovering on Thursday but unable to claw back the more-than-9% decline of the previous three days as demand concerns in major consumers overrode signals that the U.S. may pause its interest rate increases.

Russian stock indexes were higher, hovering not far from near-three-week lows.

The dollar-denominated RTS index pared losses to gain 0.9% to 1,017.9 points. The rouble-based MOEX Russian index was up 0.1% to 2,534.8 points.

Russian stocks are unlikely to see any serious buying interest before Russia's long weekend, said Sinara Investment Bank analysts. The country celebrates Victory Day on May 9.

Geopolitics are partly to blame for Russian stocks' recent decline, while investors globally fear recession, hence the sustained drop in Brent, Sinara said.
