The Russo-Ukrainian war that began in February 2022 has had a large and complex impact on the global economy. This conflict has not only changed the geopolitical landscape, but also triggered a number of economic challenges involving supply chains, inflation and energy security throughout the world. The energy sector is the most affected by this war. Russia, as one of the world’s largest oil and gas producers, faces significant sanctions from western countries. This resulted in a spike in global energy prices as many countries looked for alternatives to reduce dependence on Russian energy. Rising energy prices are the main cause of inflation in almost all countries, affecting people’s purchasing power and increasing the cost of producing goods. Meanwhile, Ukraine, as one of the main producers of wheat and grains, is experiencing major disruptions in agricultural production. This has had an impact on global food prices, which have risen sharply, especially in countries that rely heavily on imports. Countries in the Middle East and North Africa region, which rely on supplies from Ukraine, are feeling the impact more heavily, creating a potential food crisis. In terms of trade, both Russia and Ukraine experienced disruptions in their international trade flows. Sanctions imposed on Russia are forcing other countries to review trade relations. In many cases, European countries and the United States try to divert trade flows and find new suppliers, which causes uncertainty in the global market. The war also accelerated changes in monetary policy in many countries. Central banks around the world are being forced to respond to rising inflation due to surging energy and food prices. In some cases, these strategies include interest rate adjustments, potentially affecting long-term economic growth. The social impact cannot be ignored either. The economic uncertainty resulting from war causes instability in financial markets. Investors became more cautious, and fluctuations in the stock market increased. In addition, there is a risk of increased unemployment in several export- and import-dependent sectors connected to countries involved in these conflicts. Facing the impact of this war, several countries have begun to strengthen their economic resilience strategies. They are seeking to diversify sources of energy and food supplies to reduce the risks of dependence on one country. This initiative allows these countries to increase resilience amidst global uncertainty. The workforce has also been affected, with many workers losing their jobs due to business closures and production cuts. Countries with stronger social systems, such as the Nordic countries, may be able to better support their citizens through social programs. However, countries with weaker economic structures will face greater difficulties. Finally, the geopolitical impact of this war also had an impact on international organizations. The UN and other organizations are required to play a role in reducing conflict and resolving humanitarian problems resulting from war. Global cooperation is becoming increasingly important in facing emerging economic challenges. The Russo-Ukrainian War has exposed the vulnerabilities of the global economic system, and full recovery may take significant time. Countries around the world are now navigating the new challenges posed by these conflicts, seeking to rebuild their economies more resiliently and sustainably.
