Frequently Asked Questions — USD to SDG

How is the reference exchange rate calculated?

Our exchange rates are sourced from institutional data vendors and updated hourly. Reference rates reflect mid-market values on standard global exchanges.

Why do commercial banks charge a different rate than shown here?

Retail banks and currency exchanges usually apply a transaction markup or "spread" (typically between 1.5% and 5%) over the reference mid-market rate to cover service overhead. Use our Buy/Sell Spread calculator above to estimate total bank transaction costs.

Are parallel market rates legal or official?

Parallel or secondary market rates are unofficial estimates representing secondary exchange activity in specific liquidity zones. They are provided solely for comparison purposes and are never labeled as official central bank rates.
