The bank cut the key two-week repo rate to an all-time low of 0.50 percent on June 28 in response to pressure from the poor euro zone economy and budget tightening but did not commit to more easing given the crown currency's weakness.

Of the 18, fourteen said the easing cycle was already at the bottom and the next move in rates would be a hike. The remaining four said the bank would make one more 25-basis point cut by the end of the year before reversing policy.
