Abstract: The Russian-Ukrainian War saw a major escalation on February 24, 2022, when Russia invaded Ukraine, sparking the biggest battle in Europe since World War II. In addition to negatively affecting international relations, this lengthy conflict has had a significant negative influence on world markets, especially those in the Eurozone. The ongoing conflict has intensified inflationary pressures, necessitating the implementation of strong fiscal and monetary measures by the European Central Bank (ECB). This study analyzes the inflationary effect of the Russia-Ukraine crisis on the economies of the Eurozone and assesses the ECB's policies using macroeconomic models, such as the IS-PC-MR model. It explores the complex economic fallout, which includes unstable energy supply, higher industrial prices, and a decline in consumer confidence. The economy has stabilized largely because of the ECB's initiatives, which have included coordinated fiscal policies, interest rate hikes and asset purchase adjustments. Despite these initiatives, problems still exist, such as controlling the growing public debt and striking a balance between inflation management and economic growth. In order to strengthen economic resilience, the conclusion highlights the need for ongoing adaptation and international cooperation. Investments in integrated fiscal measures, diverse supply chains, and renewable energy are suggested as being crucial for long-term stability. The purpose of this study is to provide insights for future economic crisis management and to contribute to policy-making conversations.
