తరచుగా అడిగే ప్రశ్నలు

▾
Q

Why do exchange rates change?

A

Supply/demand for currencies, interest rates, inflation, economic growth, geopolitical events, central bank policy.

Q

What's the difference between bid and ask rates?

A

Bid = rate banks buy currency (you sell). Ask = rate banks sell (you buy). Spread = profit margin.

Q

Does timing matter when exchanging?

A

Absolutely. Currency moves daily/hourly. Poor timing costs 2-5% on international transfers. Lock rates when possible.
