The riel is the currency of Cambodia. There have been two distinct riel, the first issued between 1953 and May 1975. Between 1975 and 1980 the country had no monetary system. A second currency, also named "riel", has been issued since 20 March 1980. Since the 1990s citizens have used the riel alongside the U.S. dollar at the well-known rate of 4,000 KHR/USD for retail payments.

Popular belief suggests that the name of the currency comes from the Mekong river fish, the riĕl ("small fish" in Khmer). It is more likely that the name derives from the high silver content Spanish-American dollar whose value is eight reales, a coin widely used for international trade in Asia and the Americas from the 16th to 19th centuries.

The piastre was introduced in French Indochina in 1885 at par with the Spanish-American silver dollar, and was in use until 1952.

In 1953, the Cambodia branch of the Institut d'Émission des États du Cambodge, du Laos et du Vietnam issued notes dual denominated in piastre and riel with the riel being at par with the piastre. At the same time, the two other branches of the Institut had similar arrangements with the đồng in South Vietnam and the kip in Laos. The piastre itself was derived from Spanish pieces of eight (pesos).

The riel was at first subdivided into 100 centimes (abbreviated to cent. on the coins) but this changed in 1959 to 100 sen (សេន). For the first few years, the riel and piastre circulated alongside each other. The first riel banknotes were also denominated in piastres.

The 10, 20 and 50 centimes of 1953 and sen coins were minted in aluminum and were the same size as the corresponding att and xu (su) coins of Laos and South Vietnam (though without the holes in the Lao coins). A 1 riel coin about the size of a U.S. nickel was to be issued in 1970, as part of the United Nations' Food and Agriculture Organization's coin program, but was not released, perhaps due to the overthrow of the government of Norodom Sihanouk by Lon Nol.

Although the Khmer Rouge printed banknotes, these notes were not issued as money was abolished after the Khmer Rouge took control of the country.

After the Vietnamese attack Khmer Rouge in 1978, the riel was re-established as Cambodia's national currency on April 1, 1980, initially at a value of 4 riels = 1 U.S. dollar. It is subdivided into 10 kaks or 100 sens. Because there was no money for it to replace and a severely disrupted economy, the central government gave away the new money to the populace in order to encourage its use.

The first coins were 5 sen pieces, minted in 1979 and made of aluminum. No more coins were minted until 1994, when denominations of 50, 100, 200 and 500 riels were introduced. However, these are rarely found in circulation.

In rural areas the riel is used for virtually all purchases, large and small. However, the United States dollar is also used, particularly in urban Cambodia and tourist areas. In areas near the Thai border, the Thai baht is also accepted.

Dollarization started in the 1980s and continued to the early 90s when the United Nations contributed humanitarian aid, refugees began sending remittances home, and inflation as high as 177% per year eroded confidence in the riel. From 1991-1993, the United Nations Transitional Authority in Cambodia stationed 22,000 personnel throughout Cambodia, whose spending represented a large part of the Cambodian economy.

While the riel remains in common use in the provinces, the major cities and tourist areas heavily use the U.S. dollar. The latter is dispensed in ATMs, accepted in virtually all purchases, and USD quotations are required to price hotel rooms, airline tickets and significant financial transactions. Everyone knows the exchange rate of 4,000 KHR/US$ for retail trade, with riel paid out for change in fractions of a dollar.

In June 2020, the National Bank of Cambodia announced the phaseout from wide circulation of small U.S. dollar banknotes of $1, $2 and $5. This is aimed at reducing the cost of keeping the smaller US notes in circulation, as well as increasing the use of the riel in lieu of these notes. No fees were to be charged to collect these small notes before 31 August, 2020, but after that date banks were expected to incur costs of transporting these notes.
