"Pro-inflationary risks have increased significantly over the medium-term horizon," the bank said in a statement.
The central bank raised its year-end forecast for inflation - now just below 4% - to 5.0-6.5% from 4.5-6.5%, and said it was holding open the possibility of further hikes at future meetings.
"The much larger-than-expected 100bp interest rate hike ... underscores policymakers’ concerns about inflation risks," said William Jackson, Chief Emerging Markets Economist at Capital Economics.
Alfa Bank Chief Economist Natalia Orlova said the rate hike looked like a reaction to the situation on the currency market, given that the other inflation pressures mentioned had been evident at the previous central bank meeting on June 9.
Central Bank Governor Elvira Nabiullina will shed more light on the bank's forecasts and policy in a media briefing at 1200 GMT.
