Exchange Rate Determination
The exchange rate is determined by the interaction of supply and demand for a currency in the foreign exchange market. This simulation simplifies the complex forex market to show the fundamental relationship between trade flows and currency values.
Exports and Currency Demand
When a country exports goods and services, foreign buyers need to purchase the domestic currency to pay for those exports. This increases demand for the currency, which tends to appreciate its value (higher exchange rate).
Imports and Currency Supply
When a country imports goods and services, domestic buyers need to sell their currency to obtain foreign currency to pay for imports. This increases supply of the domestic currency in forex markets, which tends to depreciate its value (lower exchange rate).
Trade Balance
The trade balance is the difference between exports and imports of goods and services. A trade surplus (exports > imports) typically strengthens a currency, while a trade deficit (imports > exports) typically weakens it. However, in reality, many other factors also affect exchange rates.
Real-World Considerations
While this simulation focuses on trade flows, actual exchange rates are influenced by many factors including interest rates, inflation, political stability, economic performance, and speculative flows. Central banks may also intervene in forex markets to influence their currency's value.
