It is open source and discussed on this very board. Regarding Russian inflation figures, take into account that the yearly inflation is CUMULATIVE as well. I think it is going to be anywhere between 8-12% in Russia, lower than in Europe for sure.
In addition to that the official consumer price index is considered to be half as low as ‘people’s’ inflation but in some cases this gap can be larger - thats according to experts of Opora Rosii - non-governmental organization that represents interests of small and medium-sized enterprises. That claim is indeed to a large extent confirmed by a survey of so called houshold observed inflation (again published by the Central Bank of Russia) which reported inflation of 20,5% in August and 22,2% in July.
And although you think it is going to be between 8-12% and lower than in Europe, Russia's First Deputy Prime Minister Andrei Belousov believes inflation will come in at 12-13% in 2022 (his press conference on August 29th), whereas at the same time ECB forecsts inflation in the Eurozone to average 8,1%. Somehow I believe ECB more than you.
