The International Monetary Fund noted that economic sanctions against Russia have a very negative impact on the global economy and financial markets. There are already serious negative consequences, expressed in a sharp increase in commodity prices. The latter are now setting new records every day, unprecedented in the history of observation. They are pushed upward by the risk of supply disruptions from Russia, which is a significant exporter on the world stage. A wide range of raw materials, including energy, metals and oil, are getting more expensive. According to the fund, all countries in the world, especially the weakest economies, will feel the price increases. The biggest losers will be those with close trade relations with Russia and Ukraine. An additional disadvantage for the economies of Europe, the U.S. and some other countries will be the loss from the withdrawal of many of their major companies from the Russian market. The world stock exchanges - European, American and Asian ones - finished the last week in the red. The pressure on them was increased by the report about the fire at the nuclear power plant in Ukraine.
