The Russo-Ukrainian war that began in February 2022 has had a significant impact on the global economy. These tensions not only affect the two countries involved, but also have widespread impacts throughout the world, from energy markets to international supply chains. The energy sector is one of the most affected areas. Russia, as one of the largest oil and gas producers, influences global energy prices. Sanctions imposed on Russia by Western countries caused a spike in crude oil prices, which in March 2022 briefly reached more than $100 per barrel. Consumer countries, especially in Europe, which are highly dependent on Russian gas supplies, are experiencing an energy crisis. This encourages efforts to diversify energy sources and accelerate the transition to renewable energy, but also increases energy costs which in turn triggers inflation. Global supply chains have also been affected by this conflict. Ukraine is an important supplier of agricultural products such as wheat and corn. With exports hampered by war, many countries in Africa and the Middle East face the risk of famine, while global food prices soar. For example, wheat prices recorded an increase of more than 60% in 2022. Countries that depend on food imports have to look for alternatives, but often face higher costs. Around 244 million people are estimated to be affected by the food crisis resulting from this conflict, causing social unrest in several countries. In addition, industrial manufacturers around the world have been forced to adapt due to shortages of raw materials and components, especially those from Ukraine and Russia, such as titanium and aluminum. Macroeconomically, central banks in various countries face a dilemma between stemming soaring inflation and supporting depressed economic growth. Developed countries such as the US and the European Union have adopted tighter monetary policies, increasing interest rates. Meanwhile, developing countries, already burdened with debt, are experiencing severe inflationary pressures, leading to a potential debt crisis. Foreign investment is also affected by geopolitical uncertainty. Many companies are reducing their exposure in Russia and Ukraine, impacting the global investment climate. However, there has also been a shift towards more stable countries, such as India and Indonesia, which have the potential to attract more investors. This war also accelerated the trend of “de-globalization.” Companies are starting to actively look for alternatives to reduce dependence on supply chains that are centralized in one country. Multi-nationals are considering “nearshoring” or “friend-shoring” strategies to secure critical supplies from countries deemed politically safer. Overall, the impact of the Russian-Ukrainian war on the global economy was felt across many sectors, from energy and food to investment and monetary policy. Uncertainty still looms, and how the world responds will determine the future direction of the global economy.
