The CNB board will meet on July 26, and most analysts expect a further tightening of monetary policy by 25 basis points in the face of fresh data showing building inflationary pressures.
The CNB hiked rates by the same amount in May, in a decision hit by a minor controversy after a board member seen on the dovish side was absent. The rate vote was tied at 3-3, with the vote of Governor Zdenek Tuma deciding for an increase.
Two members missed the meeting in June -- where rates held steady -- but one was considered hawkish and the other dovish.
The key two-week repo rate currently stands at 2.75 percent, 125 points below the key euro zone rate.
