Ecuador did not adopt the dollar for tourists' convenience. It did so in the middle of an emergency, and the arrangement it chose keeps one piece of monetary independence visible in every pocket of change: the central bank still makes its own coins, even though it can no longer print notes.
Why does Ecuador use the US dollar?
An IMF working paper by Luis Jácome, published in January 2004, describes a crisis that hit 16 of the 40 banks operating in 1997. The government declared a bank holiday in March 1999 and froze deposits; by the fourth quarter of 1999 monthly inflation averaged over 5%, and in January 2000 it passed 14% in a single month. The central bank's 20-year review puts annual inflation in January 2000 at 78.07% and the average nominal wage at USD 71.2.
On 9 January 2000 the government adopted the dollar, ending a sucre that, as the Banco Central del Ecuador (BCE) notes, had circulated for 116 years. The legal switch came with the Ley para la Transformación Económica del Ecuador, published on 13 March 2000. Its first article ordered the BCE to exchange sucres for dollars "at a fixed and unalterable ratio of twenty-five thousand sucres per dollar" and barred it from issuing new notes, with one exception: fractional coins.
That exception survives. The 2014 Código Orgánico Monetario y Financiero (Article 94) makes the BCE the only body allowed to supply national metal coins, "equivalent and convertible" to US dollars, and gives them legal-tender status.
Are Ecuadorian coins real money?
Yes. You will receive Ecuadorian centavos in change alongside US cents, nickels, dimes, quarters and half dollars, and a 25-centavo Ecuadorian coin is worth exactly a US quarter. They look different, with Ecuadorian designs, but the BCE specifies them to match the coins already circulating in the country in shape, diameter, edge and weight.
The BCE's 2023 to 2025 coinage programme lists the specifications. Compared with the US Mint's own figures, the diameters line up exactly.
| Value | Ecuadorian coin diameter | US coin diameter | Ecuadorian metal |
|---|---|---|---|
| 50 cents | 30.61 mm | 30.61 mm | Nickel-clad steel |
| 25 cents | 24.26 mm | 24.26 mm | Nickel-clad steel |
| 10 cents | 17.91 mm | 17.91 mm | Nickel-clad steel |
| 5 cents | 21.21 mm | 21.21 mm | Nickel-clad steel |
The weights match too (5.670 g for both quarters, 2.268 g for both dimes), but the metal does not: the Ecuadorian 5 to 50 cent coins are 94% steel with a nickel coating, while the US coins have a copper core.
Why new Ecuadorian coins appeared after 2023
The programme document explains that the BCE had always imported most of its notes and coins from the US Federal Reserve. On 26 June 2020 the Fed told the BCE that the US Mint had cut coin production by 80% and that orders would be capped at 2019 levels, a restriction the BCE said still applied to 5, 10, 25 and 50 cent coins. The response was a plan to mint 300.2 million Ecuadorian coins worth USD 47.3 million over 2023 to 2025, replacing worn coins from 2000 to 2003.
The new series honours Ecuadorian figures chosen by the BCE, including physician and voting pioneer Matilde Hidalgo de Procel, Indigenous leader Tránsito Amaguaña, painter Oswaldo Guayasamín, novelist Jorge Icaza and footballer Alberto Spencer.
The dollar coin
The BCE's 2015 letter on large notes describes USD 5, 10, 20, 50 and 100 as the denominations "that have no metal substitute". By implication, the one-dollar note does: the US golden dollar coin. The US Mint lists it as 26.49 mm across, gold-coloured manganese brass, with a lettered edge. It is noticeably larger than a quarter, so check before handing one over as 25 cents.
Will shops take a $50 or $100 bill?
Often not. The State Department's Ecuador page, updated 18 February 2026, says plainly that "large denominations of bills are not commonly accepted." The BCE's 2015 letter explained part of the reason: USD 50 and USD 100 notes "have always" been rare in domestic transactions, and it cited the shop practice of refusing bills over USD 20.
Counterfeiting is the other reason, but not in the way many visitors assume. The BCE's counterfeit guidance, last updated in June 2024, says the most counterfeited notes are the USD 20, followed by the USD 5. It asks people to check the watermark and security thread against the light and the colour-shifting ink on 10, 20, 50 and 100 notes, right after an ATM withdrawal or bank visit. A note a bank suspects is fake is retained and sent to the BCE for verification, so you lose it until then.
Cash, cards and change in practice
The State Department says most establishments accept debit and credit cards and phone wallets, but that you should be ready to pay in cash in remote areas and small towns. It also notes that most hospitals and medical professionals want cash or a local bank transfer, and that ATMs taking US cards may charge high fees. Day trips work the same way: a ticket for the Mitad del Mundo equator site north of Quito is a dollar price like any other, and small notes make the queue quicker.
A worked example shows why small notes matter. Pay a USD 4.35 bill with a USD 20 and you are owed USD 15.65: typically a 10, a 5 and 65 cents, which might come as one Ecuadorian and one US quarter, a dime and a nickel. Pay the same bill with a USD 100 and the vendor must find USD 95.65, which a small café or market stall may simply not have.
Coins can run short in daily trade too. The BCE's coin-dispensing machines are mapped on its notes and coins page; in Quito the list includes the BCE head office on Avenida 10 de Agosto, the Museo Numismático at García Moreno and Sucre, the Santa Clara and Iñaquito markets and the Quitumbe bus terminal, and in Guayaquil one stands at José Joaquín de Olmedo airport.
The same logic holds outside Quito: if you are heading to Cuenca to buy a hat, our guide to toquilla straw and Panama hats in Cuenca helps you judge the price before you count out the notes. Before your first day out, check your wallet: if the smallest note in it is a USD 50, your first stop should be a bank counter, not a taxi.
