What causes exchange rates to change?

The exchange rates of the euro, the dollar, the pound, and other currencies can fluctuate several times even within a single day. Because of this, it’s possible that for the same amount in forints, we’ll receive more foreign currency one day and less the next.

But what actually determines a currency’s exchange rate?

Supply and Demand in the Foreign Exchange Market

Currency exchange rates are fundamentally determined by supply and demand. If demand for a particular currency increases, its exchange rate typically strengthens.

The foreign exchange market operates continuously around the world, so exchange rates can be influenced by a wide range of economic and financial events.

Central Bank Interest Rates and Economic Data

Central banks’ interest rate decisions can have a significant impact on exchange rates. In addition, investors monitor, among other things:

inflation trends,
economic growth,
unemployment data,
central bank decisions,
and major international events.
Unexpected economic or political news can cause significant exchange rate fluctuations even in a short period of time.

Why is this important when exchanging currency?


If you want to exchange a large amount for euros, dollars, or another currency, the current exchange rate can make a significant difference.

That’s why it’s a good idea to check the latest exchange rates before exchanging money, rather than choosing a currency exchange service solely out of habit.

No one can predict with certainty how exchange rates will change in the future, but by comparing current rates, you can make a more informed decision.
