Why do currency rates change daily?

Currency rates change daily due to dynamic processes taking place in the financial market. The most important factors influencing their fluctuations are: supply and demand for a given currency, decisions of central banks regarding interest rates, macroeconomic data such as inflation or GDP, as well as geopolitical events and global crises.

Investor speculation on the Forex market can also lead to sudden changes in rates. For example, an increase in demand for the US dollar may increase its value relative to other currencies. Seasonal factors, such as holidays or the end of the year, may also influence exchange rate fluctuations.
