The Russo-Ukrainian war, which began in February 2022, has created a significant impact on the global economy, affecting sectors ranging from energy to food. In this context, it is important to understand the profound changes that occurred. First, the energy sector is facing major disruption. Russia is one of the world’s main producers of oil and natural gas. When international sanctions were imposed, energy supplies to Europe, which is heavily dependent on Russia, were disrupted. Crude oil prices rose sharply, reaching their highest level in years. This causes global inflation which impacts the costs of transportation and goods, reducing consumer purchasing power. Second, the food sector is experiencing a crisis. Ukraine is known as the “world’s grain granary”. The war disrupted the planting and harvesting processes, as well as the distribution of agricultural products. Food prices on international markets have increased significantly. Countries that depend on wheat imports from Ukraine, such as several countries in the Middle East and Africa, face the risk of famine. In addition, the rate of inflation is increasing throughout the world. Many countries, including members of the European Union, recorded their highest inflation in the last decade. Central banks in various countries have been forced to raise interest rates to try to stabilize the economy. However, this can slow economic growth and increase borrowing costs for businesses and individuals. Supply chain disruptions are also a big problem. Many companies around the world, especially those in the technology and manufacturing sectors, have experienced production delays. Demand for goods remains high, but shortages of components and raw materials are hampering production capabilities. As a result, many companies increase prices which can reduce profit margins. From an investment perspective, political and economic uncertainty has caused investors to tend to switch to safer assets, such as gold or government bonds. This can lead to high volatility in the stock market, where many companies experience sharp price fluctuations. The social impact cannot be ignored either. With rising energy and food prices, layers of society are at risk of experiencing dissatisfaction. Demonstrations in several countries against the rising cost of living show how sensitive society is to this ever-evolving situation. Overall, the impact of this war has created waves that spread throughout the world. The affected economic sectors are interconnected, creating a domino effect that can last for a long period of time. Countries need to adjust their economic policies to adapt to this new reality, to prevent a deeper crisis. Global economic sustainability depends on collaborative efforts to address these challenges effectively.
