Formula
What is the Bank of Mongolia official rate?
The Bank of Mongolia (Mongolbank) publishes official reference rates for the tugrik every business day. The USD rate is set as the weighted average of interbank market trades, while other currencies are derived from international cross rates. On weekends and holidays the last business day's rate remains in effect.
The official rate is widely used as the reference for accounting, tax reporting and contract settlements.
Why do bank rates differ from the official rate?
Commercial banks and exchange offices set their own buy and sell rates. The gap between them (the spread) covers the institution's income and risk, so seeing a 1–2% difference from the official rate at a bank counter is normal. Cash and non-cash transactions are also priced differently.
When exchanging a large amount, compare rates across several banks — a smaller spread saves real money.
When and where do this page's rates come from?
Rates in the Mongolbank tab are based on the Bank of Mongolia's official reference rates; the page refreshes them hourly. Cross rates in the International tab come from the European Central Bank (ECB) reference rates, which update once per working day around 16:00 CET, so no intraday movement will show.
If your connection drops, the most recently saved rates on your device are used — so a slightly outdated rate may be shown.
