Currency Exchange Rates Explained: How Global Forex Markets Determine Currency Values
An insider look at foreign exchange: how central bank interest rates, inflation differentials, and geopolitics move currency pairs across global interbank trading desks.
The $7.5 Trillion-a-Day Market
The foreign exchange (Forex) market is the largest and most liquid financial market on Earth, trading over $7.5 trillion daily. Unlike stock markets, Forex has no centralized exchange; trading occurs electronically over-the-counter (OTC) between central banks, hedge funds, commercial banks, and multinational corporations 24 hours a day.
3 Core Drivers of Currency Valuation
- Interest Rate Differentials: Higher interest rates set by central banks (such as the US Federal Reserve or Reserve Bank of India) attract foreign capital seeking higher yields, boosting currency value.
- Inflation Rates: Countries with consistently lower inflation experience currency appreciation as purchasing power increases relative to other currencies.
- Current Account Deficits & Trade Balance: When a nation imports more goods and services than it exports, it must sell its currency to purchase foreign exchange, putting downward pressure on its currency.
