The Foreign Exchange (Forex) market is the largest and most liquid financial market globally. Unlike the stock market, which operates during specific hours via centralized exchanges, the Forex market is a decentralized, over-the-counter (OTC) market operating 24 hours a day, five days a week.
Whether you're planning a vacation, sending money abroad, or looking to trade macro trends, understanding the basics of currency exchange is essential.
What is a Currency Pair?
Currencies are always traded in pairs. You cannot simply "buy an Euro"; you must buy Euros *using* another currency, like US Dollars. This creates an exchange rate.
This means that 1 Euro (the base currency) is equal to 1.10 US Dollars (the quote currency).
1. The Base Currency
This is the first currency in the pair (e.g., the EUR in EUR/USD). It is the currency you are buying or selling. The value of the base currency is always exactly 1.
2. The Quote Currency
This is the second currency (e.g., the USD in EUR/USD). It tells you how much of this currency it takes to buy exactly one unit of the base currency.
What Moves Exchange Rates?
In a floating exchange rate system (which most major global currencies use), prices are determined by supply and demand. Several massive economic forces dictate that demand:
- Interest Rates: Central banks (like the US Federal Reserve or the European Central Bank) set interest rates. Generally, higher interest rates offer lenders in an economy a higher return relative to other countries, attracting foreign capital and causing the exchange rate to rise.
- Inflation: Countries with consistently lower inflation rates generally exhibit rising currency values because their purchasing power increases relative to other currencies.
- Economic Performance: GDP growth, low unemployment, and a strong manufacturing sector attract foreign investment.
- Geopolitical Stability: In times of global crisis, investors flock to "safe-haven" currencies like the US Dollar (USD), Swiss Franc (CHF), or Japanese Yen (JPY).
