Monetary policy plays a crucial role in ensuring a country's economic security by influencing national economic processes. Effective monetary policy helps regulate money circulation, stabilize currency value, and promote economic growth. In Ukraine, monetary security depends on the National Bank's monetary policy. By strengthening coordination between fiscal and monetary policy, maintaining a tight monetary policy during crises, and increasing trust in the banking system, monetary risks and threats can be minimized. A clear and effective monetary policy is essential for maintaining a sufficient level of monetary security.
