Is this a joke, or what?

Mongolian central bank is going to raise it's policy rate from 9.5% to 14%!

Please, someone, brighter than me explain to me, WTF is that?

I wish today was April fool's day! Not yet, so what this implies? MNT will appreciate against others, parched market will not see the much needed money to quench the thirst. Chaining entire economy and sentencing businesses to death!
