Some time ago, the Federal Anti-monopoly service of the Russian Federation stated that a conspiracy of traders speculating with ginger was prevented. This meant that in many regions, the cost was rolled back to the previous values of 400-700 rubles per kg, as compared to 3,000 to 7,000 in March.
However, prices eventually dropped even further; in some places, ginger is traded for 200-300 rubles per kg or less. However, experts warn: as soon as the stocks sell out, prices will rise even stronger than before the crisis.
In late March, the Russian media reported that ginger supposedly had medicinal properties to fight off viruses, and prices immediately jumped. But the hype was short-lived, the myth of the magical properties of ginger have been debunked.
As for other, equally mythical products to combat the Corona-virus: the price of lemons will probably not drop. This product is not produced in Russia in sufficient volumes and the supply of lemons from abroad depends on the ruble/dollar exchange rate. As the ruble will probably continue to devalue, of lemons will get somewhat more expensive.
