Why are currency courses changing every day?

Currency courses change every day due to dynamic processes on the financial market. The most important factors affecting 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.

Investors’ speculations on the Forex market can also lead to rapid changes in courses. For example, an increase in demand for an American dollar can increase its value against other currencies. Seasonal factors, such as holidays or the end of the year, can also affect exchange rate fluctuations.
