PRAGUE, Sept 17 (Reuters) - The debate inside the Czech central bank is about how quickly and to what level interest rates should rise, Vice-Governor Tomas Nidetzky said on Friday, rather than if high inflation is a blip. “So far the (European Central Bank) isn’t planning to react much to high inflation, as it expects it to return to the target itself,” Nidetzky said in comments published on the bank’s website. “The Czech situation is different: we don’t need reasons to start tightening. We are now thinking more about how fast we should raise rates and to which level,” he said in a comment posted along with a presentation he gave at an American Chamber of Commerce roundtable.
