They are spending all of their cash on war production, which actually (combined with workforce shortages leading to higher wages) has resulted in unexpectedly high GDP growth.
However that's mostly fuelled by Russia spending all of their reserves (effectively they are literally burning money) to fund the war. There are actual reasons why they had to raise their interest rates to 21% despite inflation supposedly being below < 10%.
When that money runs out? Who knows.. Russia can hardly borrow in international markets. They'll have to either start printing money or the economy will crash. Well hopefully before they actually "win" the war. On the bright side their economy might crash anyway if the war is over (due to extremely high government spending propping it up, a bit like the situations immediately after WW1/2 in Britain or even the US).
