Currency Converter

Exchange rates are driven by: Interest rate differentials (higher rates attract foreign capital). Inflation (lower inflation → stronger currency). Trade balance (surplus → stronger). Political stability and economic performance. Market speculation. Central bank interventions. The USD is the world reserve currency, so many commodity prices (oil, gold) are denominated in USD.

When exchanging currency, banks quote two rates: bid (what they buy at) and ask (what they sell at). The difference is the spread — their profit. Airport exchange booths have the widest spreads (worst rates). Banks and online platforms offer better rates. For large amounts, negotiating the rate is possible.

Best options (best to worst): Notify your bank and use your debit card at local ATMs abroad. Use a no-foreign-transaction-fee credit card. Exchange at a local bank in the destination country. Worst: airport currency exchange booths (high spreads), hotel desks, pre-purchased travelers checks. Never use dynamic currency conversion (DCC) which forces you to pay in your home currency.

PPP adjusts exchange rates to account for price differences between countries. The Big Mac Index (by The Economist) is a famous example: if a Big Mac costs $5 in the US and €4 in Europe, the PPP exchange rate is $1.25/€. GDP comparisons often use PPP to give a more accurate picture of economic output and living standards.

Strongest (highest value per unit vs USD, 2024): Kuwaiti Dinar (~$3.27/KWD). Bahraini Dinar (~$2.65). Omani Rial (~$2.60). British Pound (~$1.27). Weakest (largest units per USD): Iranian Rial (~42,000 IRR/USD). Vietnamese Dong (~25,000 VND/USD). Indonesian Rupiah (~15,700 IDR/USD). Note: high units do not mean weak economy.
