premise: ISTANBUL, March 17 (Reuters) - Turkey’s central bank said on Tuesday it would maintain tight monetary policy until there was a significant improvement in the outlook for inflation. In a statement accompanying its decision to leave key interest rates unchanged, the bank said favourable developments in trade and the moderate course of consumer loans would help Turkey’s current account balance to improve.
hypothesis: Turkey’s central bank knows exactly what inflation will be in the future. 
reason: They may or may not know this. They may know what it will be in the very near future... for instance, the next day. They may not know what it will be beyond that. You can't know if this is right.
