The average price of butter in the Altai Territory of Russia has surpassed 600 rubles per kilogram, with cheese prices being similarly high. The most expensive oil is in Rubtsovsk at 622 rubles per kilogram, while the most affordable is in Barnaul at 589.5 rubles per kilogram. This price hike, the first since 2016, is due to increased costs, reduced Belarusian butter exports, and fraud. Food manufacturers are planning to further increase prices for their products, affecting consumers in February or March.
