Currency Converter Guide: Exchange Rates, Forex, and Travel Money
Currency conversion affects virtually every international transaction—whether you're a tourist, business importer, investor, or student studying abroad.
How Exchange Rates Work
Rates fluctuate based on interest rates, inflation, economic performance, political stability, and market speculation.
The Hidden Cost: Bid-Ask Spreads
Example (EUR/USD):
Bid: 1.0850 | Ask: 1.0950 | Spread: 0.0100 (~0.92%)
Converting $1,000 → €913, then back → $991
Instant loss: $9 (0.91%)
