This article is from today, but the data is still 5 days old. Obviously it’s hard to get stats on daily inflation numbers, but it seems clear that food prices have gone up as a result of the fuel shortage.
AFAIK prices on fuel in Russia are regulated, which prevent the oil companies from increasing prices at the pump to make cost and demand meet, resulting in this enormous fuel shortage, with hour long waiting lines. (and zero fuel for average people in Crimea).
I mentioned this a couple of days ago, and now the evidence is trickling in.
