Financial sciences are considered one of the most important branches of economic sciences, focusing on money management and decision-making related to investment, financing, and saving. They aim to efficiently use financial resources to maximize benefits and minimize risks, covering areas such as public finance, corporate finance, financial markets, and risk management.

Financial markets help allocate savings into productive investments, while risk management focuses on identifying and reducing financial risks. Modern financial sciences have evolved due to technology and globalization, introducing tools like fintech and digital currencies.
