How Exchange Rates Work: The Complete Mechanics
Exchange rates are determined by the supply and demand dynamics in the global forex market. When demand for a currency increases, its value rises. When demand falls, its value decreases. But what drives supply and demand?
The Basic Mechanics
USD/INR = 83.50
This means 1 US Dollar (base currency) = 83.50 Indian Rupees (quote currency)
Floating Exchange Rates
Determined entirely by market forces of supply and demand. Most major currencies (USD, EUR, GBP, JPY, CAD, AUD, CHF) use this system. Rates change constantly based on economic factors, news, and market sentiment.
✓ Used by: US, Eurozone, UK, Japan, Canada, Australia, Switzerland
Fixed (Pegged) Exchange Rates
Pegged to another currency (often USD), a basket of currencies, or gold. The central bank actively maintains the peg by buying/selling its own currency.
✓ Used by: Saudi Arabia (USD peg), UAE (USD peg), Hong Kong (USD peg), Denmark (EUR peg)

How to Read Exchange Rates: Bid, Ask, and Spread
Example: EUR/USD Quote
1.0850 / 1.0853
Bank BUYS EUR, SELLS USD
Cost of transaction
Bank SELLS EUR, BUYS USD
💰 Bid Price
The price at which a market maker (bank, broker) is willing to BUY the base currency. This is what you get when SELLING currency.
Example: If EUR/USD bid is 1.0850, you get $1.0850 for each €1 you sell
📈 Ask Price
The price at which a market maker is willing to SELL the base currency. This is what you pay when BUYING currency.
Example: If EUR/USD ask is 1.0853, you pay $1.0853 for each €1 you buy
📏 Spread
The difference between bid and ask prices. This is how banks/brokers make money. Lower spread = better deal for you.
Example: 3 pips spread = 0.0003 difference = $3 cost per $1,000 exchanged
