State reserves ?

If you take a look on the Russian Ruble we really had a all Time High at 177 points like never before in history. But in one day it changed and has fallen back to 110 points about. Although Russia is the most sanctioned country in on the world right now.

The situation with the Russian currency really remembered in the situation with the Turkish Lira where president Erdoğan took action over the night. So what the Russian central bank did ?

What are your thoughts?
