The Russian Central Bank will increase the refinancing rate from 8% to 8.25% and the deposit rate from 3% to 3.25% on Tuesday.
Inflation in the year to 25 April stood at 9.6%.
"Everything is directed to battling inflation. That is set as the number one task," said Olga Sterina at Uralsib.
"The central bank decided to take a pre-emptive step. Before there were a lot of concerns about the slowdown in economic growth but... our monetary authorities are not concerned about a slowing economy against the backdrop of high oil prices," she added.
A similar rate rise in February was the first since 2008.
The rouble has risen against the dollar to its highest since December 2008.
