I mean 1000:1 or lower.
Russia has had a steady budget surplus for many years and its external debt is relatively low. I'll tell you more, now all imports to Russia are blocked by almost 100% and exports are blocked by only 30%. This makes Russia's foreign trade balance very strongly positive, although it was positive before. I hope you have enough economic literacy to understand that a positive foreign trade balance favorably affects the national currency. If you do not buy anything, but continue to sell, although less and at a discount, you will have more money, not less. Is it too difficult to understand?
Rumors of the death of the already twice "torn to shreds" (the first time after the annexation of Crimea in 2014) of the Russian economy are greatly exaggerated. Try to learn how to live with it somehow.
As one of the measures, the cessation of uranium supplies to the United States is now being discussed. This will make electricity much more expensive. I think Russia's economic response to sanctions will focus on simple basic things - electricity, gasoline, food. Due to the quantitative easing programs that have intensified against the background of the pandemic, these simple basic things have already risen in price noticeably (multiple!) even before the invasion of Ukraine. Russia is always ready to lend a helping hand to friendly countries, but not to unfriendly countries. Now there are 48 states in the list of unfriendly countries of Russia. And I think many of them will want to get out of there very soon, when they feel the economic burden from the consequences of their own short-sighted decisions more fully. Because hunger is not an aunt.
It doesn't matter how much money you have if truckers have blocked the roads due to high gas prices and the shops have run out of food. Think about it at your leisure.
