Basically Russia is demonstrating power with their military operations in Ukraine which is important for your fiat currency. So that is a win for the russian ruble. They are also loosely pegging it to gold which arguably makes a fiat currency ever so slightly stronger. So thats another win for the ruble. Russia also has a significant energy surpluss so its a good place for industry unlike for example most of Europe. Its just going to lead to a stronger ruble overall imo. But that being said i am not a macro economist, im just piecing together what i read in the news and trying to give my best guess. So i believe the Russian ruble has turned around its decade long decline vs the USD and other currencies unless something major changes.
