Which product has gotten the most expensive worldwide in the past month?

I don't know what exactly got more expensive the most over this month - that kind of data comes out with a delay and depends on which source you're looking at. But generally speaking, yeah, global price increases do affect prices in Russia, especially when it comes to imported components, equipment, or energy resources. It's better to just keep an eye on prices for stuff you buy regularly - you can usually spot significant price hikes in supermarkets or on marketplaces within a week or two.

I don't have exact data on any specific commodity over the last month in my head, and besides, those kinds of reports usually come out with a lag anyway. But overall, global prices for energy resources, metals, and agricultural products are constantly fluctuating, and yeah, that eventually makes its way to Russian stores.

How much it affects our prices depends on what exactly is getting more expensive. If it's oil or gas - that's going to hurt more, because Russia is a major producer and exporter of those. If it's, say, cocoa or rare metals that we import, then the price increase will take a couple of months to reach us. Food prices go up the fastest, because logistics and processing are sensitive to sudden price spikes.

You can always prepare for price increases, but there's no need to panic - just stock up on what you need the normal way, don't rush to the supermarket in a panic. If you want to track specific goods, just check the prices at your own stores - that'll give you a real picture better than rumors about global trends.
