Sint Maarten (Dutch Part) Currency & Money Guide: Exchange, Cards, and Tips

Sint Maarten (Dutch Part) uses the Netherlands Antillean Guilder (ANG/NAf) as its official currency, but the US Dollar is accepted everywhere at a nearly universal fixed exchange rate. For most travellers, carrying USD cash for small purchases and using a credit card for larger expenses is the most efficient strategy, especially when paired with the Hello app to track multi-currency spending. You can easily stay connected and manage your budget by using a Hello eSIM for Sint Maarten (Dutch Part) to access real-time exchange rates and banking apps on the go.

While the Netherlands Antillean Guilder (NAf or ANG) is the official currency of Sint Maarten (Dutch Part), the island operates on a dual-currency system where the US Dollar is king. The exchange rate is officially pegged at 1.79 NAf to 1 USD, though most local businesses simplify this to 1.80 NAf for easier calculation. If you are visiting from Singapore, as of May 2026, 1 SGD is approximately 1.33 NAf.

You will often see prices listed in both currencies, particularly in supermarkets and gas stations. However, in the tourist-heavy areas of Philipsburg and Simpson Bay, USD is the primary language of commerce. It is rarely necessary to exchange your money into guilders; in fact, most ATMs provide the option to withdraw USD directly. To keep your finances organized, the Hello app is an invaluable companion. It features multi-currency tracking with automatic exchange rate conversion, allowing you to log a lunch in Guilders and a souvenir in Dollars while seeing the total impact on your budget in your home currency. This is particularly helpful because change is often given in guilders even if you pay in dollars, a quirk that can make manual budgeting a headache.

Credit card acceptance is high across the Dutch side of the island, especially at hotels, high-end restaurants, and car rental agencies. Visa and Mastercard are the most widely accepted, while American Express is taken at larger resorts. Contactless payments via Apple Pay and Google Pay are becoming standard in 2026, though smaller beach bars and local 'lolo' eateries still prefer cash.

When using your card, always choose to be charged in the local currency (NAf) or USD rather than your home currency to avoid poor Dynamic Currency Conversion (DCC) rates. ATMs are plentiful in areas like the Princess Juliana International Airport and along the Front Street shopping district. Most ATMs, such as those operated by Windward Islands Bank (WIB), charge a foreign transaction fee ranging from $5 to $10 USD per withdrawal. To avoid multiple fees, it is wise to withdraw larger sums at once. Before heading out, ensure you have a Hello eSIM for Sint Maarten (Dutch Part) active. Having reliable data allows you to instantly freeze your card via your banking app if it’s misplaced or to verify transaction alerts in real-time, providing an essential layer of financial security while exploring the island.

Tipping in Sint Maarten (Dutch Part) is common practice and follows a hybrid of European and North American standards. In many restaurants, a 'service charge' of 15% is automatically added to the bill. It is important to check your receipt carefully; if service is included, an additional tip is not required but 5-10% is appreciated for exceptional service. If service is not included, a standard tip of 15-20% is the norm.

For other services, tipping is straightforward. Taxi drivers typically receive $2-$5 USD depending on the length of the trip and help with luggage. Porters at the airport or hotels usually expect $1-$2 USD per bag. For tour guides, a tip of 10-15% of the tour cost is standard. According to the St. Maarten Tourism Bureau, the island welcomed over 1.5 million cruise passengers in 2024, many of whom rely on cash for quick tips at the pier. Keeping a stash of $1 and $5 USD bills is highly recommended for these small interactions. If you are travelling with a group, the Hello app’s expense splitting feature makes it incredibly easy to divide these tips and shared costs fairly, even if members are paying in different currencies.

Sint Maarten is one of the more expensive Caribbean destinations, but savvy planning can keep your costs manageable. In 2026, a mid-range daily budget typically falls between $150 and $250 USD per person, covering accommodation, meals, and local transport. One of the best ways to save is to take advantage of the island's duty-free status; alcohol, tobacco, and high-end jewelry are significantly cheaper here than in most of the world.

To save on food, visit the local 'lolos' (open-air BBQ stands) where a massive plate of ribs, chicken, and sides costs roughly $15-$22 USD, compared to $40-$60 USD at a sit-down restaurant in Simpson Bay. Another tip is to use the local 'bus' system—minivans with signs in the window—which cost only $1.50 to $3.00 USD per ride, a fraction of the cost of a taxi.

Sint Maarten is generally safe, but tourists should remain vigilant against common financial pitfalls. One frequent issue is the 'Double Tip' scam, where a server might imply that service is not included even when a 15% charge is already on the bill. Always ask 'Is service included?' before adding more. Another concern is card skimming, particularly at isolated ATMs. Stick to ATMs located inside banks or well-lit shopping malls.

In the taxi industry, always agree on the fare before getting into the vehicle. While fares are technically regulated by the government based on zones, some drivers may attempt to overcharge unsuspecting tourists. Using the Hello app to log your expenses immediately via voice entry or AI receipt scanning helps you stay aware of your spending patterns and quickly spot any discrepancies or overcharges. If you do encounter a dispute, having a record of your expenses and a live data connection via a Hello eSIM allows you to look up official fare charts or contact your hotel for assistance instantly.

Can I use Euros on the Dutch side? While Euros are the official currency on the French side (Saint Martin), they are generally not accepted on the Dutch side, or if they are, the exchange rate offered by vendors will be very poor. It is much better to use USD or NAf.

Are there plenty of ATMs? Yes, ATMs are widely available in all major towns and at the airport. Most will dispense both USD and NAf.

Is it better to pay in cash or card? For the best protection and exchange rates, use a travel-friendly credit card for larger purchases. However, keep cash for taxis, small beach bars, and tips.

Do I need to notify my bank before traveling? Yes, always inform your bank of your travel plans to prevent your card from being flagged for suspicious activity. With a Hello eSIM, you can easily access your banking app to manage travel notices or check your balance without hunting for insecure public Wi-Fi.
