French Guiana Currency & Money Guide: Exchange, Cards, and Tips

French Guiana uses the Euro (€) as its official currency, and while credit cards are widely accepted in urban centers like Cayenne, cash is indispensable for rural adventures. Travelers should expect prices similar to or higher than mainland France, making diligent budget tracking with the Hello app essential for a stress-free trip.

As an overseas department of France, the official French Guiana currency is the Euro (€). This makes the territory unique in South America, as it operates under European monetary regulations. For travelers arriving from Singapore, the French Guiana exchange rate in early 2026 sits at approximately 0.68 to 0.70 Euros for every 1 Singapore Dollar (SGD). Because French Guiana is part of the Eurozone, you will find that prices for imported goods and services are significantly higher than in neighboring Brazil or Suriname.

Exchanging money locally can be a challenge. Most banks in Cayenne, such as BNP Paribas or La Banque Postale, primarily serve residents and may charge high commissions for currency exchange. It is highly recommended to exchange your SGD or USD for Euros before you depart. If you find yourself needing to track your spending across different currencies, the Hello app features a multi-currency expense tracker that automatically applies live exchange rates, ensuring you know exactly how much you are spending in your home currency. This is particularly useful when navigating the high costs of the Amazonian frontier.

Credit cards and contactless payments are the standard for most transactions in Cayenne, Kourou, and Saint-Laurent-du-Maroni, but cash remains the primary medium in remote jungle villages. Visa and Mastercard are the most reliable options, while American Express is rarely accepted outside of high-end hotels or the Guiana Space Centre. Most merchants have a minimum spend for card transactions, typically around €10 to €15, so always keep small change on hand for bakeries or local markets.

ATMs, known locally as distributeurs, are readily available in major towns. However, if you are heading into the interior—such as the Maroni River settlements or Saül—you must withdraw all the cash you need beforehand, as ATMs are non-existent in the deep jungle. To find the nearest bank or navigate to a local market, staying connected is vital. You can activate a Hello eSIM for French Guiana before you arrive to ensure you have instant data for GPS and banking apps. When using ATMs, always choose to be charged in the local currency (EUR) rather than your home currency to avoid the predatory exchange rates often associated with Dynamic Currency Conversion (DCC).

Tipping in French Guiana follows the French tradition where service is usually included in the price, meaning large tips are not expected but small gestures are appreciated. In restaurants, the bill will typically state service compris, but it is customary to leave the small change or round up to the nearest €5 for exceptional service. For taxi drivers, rounding up to the nearest Euro is standard practice.

When engaging in specialized tourism, such as guided tours of the Amazon or boat trips along the coast, tipping culture is slightly more pronounced. It is polite to tip your guide approximately €5 to €10 per day, depending on the complexity of the excursion. According to the Comité du Tourisme de la Guyane, the territory welcomed over 100,000 visitors in 2023, many of whom participate in these eco-tours. If you are traveling in a group, the Hello app’s expense splitting feature is a lifesaver; it allows you to divide these tips and tour costs among friends instantly, even if everyone is using different currencies.

Traveling through French Guiana is a premium experience, with costs often exceeding those of mainland France due to the high price of importing goods. In 2026, a mid-range traveler should budget between €130 and €190 per day. Data from the IEDOM (Institut d'Émission des Départements d'Outre-Mer) indicates that consumer prices in French Guiana are roughly 12% higher than in hexagonal France, largely driven by food and fuel costs.

To save money, consider eating at local "lolo" stalls or visiting the vibrant markets in Cayenne for fresh produce rather than relying on expensive supermarkets. Drinking tap water is generally safe in urban areas, which can save you several Euros a day compared to buying bottled water.

Using the Hello app to scan your receipts as you go will help you stay within your budget and avoid the "sticker shock" that often comes with a trip to this unique corner of South America.

While French Guiana is relatively safe, travelers should be mindful of common French Guiana money tips regarding safety and overcharging. The most frequent issue involves "tourist pricing" at informal markets or with unlicensed taxi drivers. Always confirm the price of a service—whether it is a pirogue (boat) ride or a taxi trip—before you start your journey. In Cayenne, be cautious of your surroundings when using outdoor ATMs, especially at night; it is always safer to use a machine located inside a bank lobby.

Another practical tip is to keep your cash and cards in a waterproof container. The tropical climate means sudden, heavy downpours are common, and if you are traveling by river, there is always a risk of your belongings getting wet. If you lose a receipt or forget how much you spent on a boat transfer, you can use the Hello app’s voice expense entry to log the cost immediately. This ensures your records are accurate even when you are on the move in the middle of the rainforest.

Navigating a new currency can be confusing, so here are the most common questions answered directly. Can I use US Dollars in French Guiana? No, US Dollars are not accepted; you must use Euros for all transactions. Is French Guiana expensive? Yes, expect to pay prices comparable to Paris or slightly higher due to import taxes.

Do I need to carry a lot of cash? Yes, especially if you plan to leave the main cities. While Cayenne is modern, many jungle lodges and river transporters only accept cash. Are digital wallets popular? Apple Pay and Google Pay are widely accepted in supermarkets and larger stores in Cayenne and Kourou, but they are not used in local markets or smaller villages. To ensure you can always access your digital wallet or banking app, make sure you have a reliable Hello eSIM for constant data coverage. Finally, is there a departure tax? No, there is no specific cash departure tax for tourists leaving via Cayenne-Félix Eboué Airport, as these fees are typically included in your flight ticket.
