Banks & Currency
The official currency in Cambodia, the Cambodian riel, trades at around 4,000 riels to the US dollar. But there’s a 90 percent level of dollarization in the country. What this means is that you don’t need to be concerned about getting riel when you arrive in Cambodia. The visa you get on arrival must be paid for in US dollars.
No worries about changing money — the US dollar is Cambodia’s unofficial second currency.
