Riel which has adopted as the sole official name of Cambodia’s currency has experienced two different periods in accordance with two distinct versions throughout the history. Riel was first introduced in 1953 but until 1975, it was no longer in circulation; at that time, Cambodia did not have any monetary system. It was not until 1980 that another currency whose name was also Riel was issued in Cambodia. Despite the fact that Riel is the national currency, it has been less common than U.S. dollar in Cambodia since 1993.
Indonesia’s monetary system consists of two types: banknotes and coins. The coin includes 6 denominations 50, 100, 200, and 500 Riels, almost all of which are taken out of circulation. Banknotes come in 10 denominations of 50, 100, 500, 1,000, 2,000, 5,000, 10,000, 20,000, 50,000, 100,000 Riels.

In terms of riel currency exchange rate, one dollar has equaled to 4121.25 riels (August 2016). Because U.S dollar is the most common currency in Cambodia, it is unnecessary to exchange U.S dollar for Riel prior a Cambodia shore excursion. You can use U.S dollar to pay for both small souvenirs along the street and a restaurant meal. However, if you intend to visit the countryside, remember to exchange your money for Riel as the locals usually sell goods for riel notes. If you cannot exchange the money prior to your excursion, don’t worry as you may exchange it in many money changers in large markets in Phnom Penh such as Phsa Thmey market, Russian market, and Orusey market.
