The Russian ruble in 1992-03 lost most of its value. Pensioners were paid, but they lost most of the value in the conversion to new Rubles - 35,000 to 35 new. They were somewhat better prepared with many people accustomed to growing small gardens for vegetables they couldn’t buy. Even so it was a difficult time and average lifespans went down by several years. Affected men particularly hard.
Here most people don’t grow anything even in the country. Suspect Murcans will not be patiently standing in lines for a bag of food/water like the Japanese after the 2011 tsunami.
