Currency, Money & Tipping in St. Martin/St. Maarten

Currency by Side

The U.S. Dollar (USD)

USD a St. Martin and St. Maarten accepted currency

The U.S. dollar is accepted on both sides of the island, making it an incredibly convenient option for American tourists. Whether you’re shopping in Philipsburg on the Dutch side or dining in Marigot on the French side, you’ll find that many businesses price their goods and services in dollars, or at least accept dollars as payment.

This widespread acceptance of the U.S. dollar reduces the need for visitors to exchange large amounts of money into guilders or euros, especially for short stays. However, it’s important to be aware of the exchange rates offered by individual businesses, as they may not always match the official rates. In most cases, paying with U.S. dollars is straightforward, but it is advisable to carry smaller denominations to avoid receiving change in a less familiar currency.

The Euro (EUR)

EURO a St. Martin (French side) accepted currency

The French side officially runs on the euro, since France (and by extension its overseas collectivity of Saint-Martin) is part of the European Union. Most restaurants, shops, and hotels post prices in euros, and card terminals will typically charge you in euros as well.

That said, US dollars are widely accepted, especially in tourism-heavy spots like Marigot, Orient Bay, and Grand Case. A few things to keep in mind:

• Card payments will typically process in euros on the French side.

• Cash can be EUROS or USD: mixing the two to pay a bill is generally fine.

• If you're booked with St. Martin Sotheby's Realty, your villa concierge will sort out any currency confusion.

• Exchange rates baked into restaurant or boutique bills aren't always favorable: check what rate they're using before deciding whether to pay in euros or dollars.

Quick tip: to estimate the USD cost of a EURO price, multiply by roughly 1.15. A €50 dinner runs about $57.

The Caribbean Guilder (XCG)

XCG a St. Maarten (Dutch side) accepted currency

The Dutch side's official currency is the Caribbean Guilder (XCG), which replaced the Netherlands Antillean Guilder (ANG) in 2025 as part of a currency modernization across Curaçao and Sint Maarten. The guilder is legally pegged to the US dollar at a fixed rate of $1 = 1.79 XCG, so unlike the euro, this exchange rate never fluctuates (Centrale Bank van Curaçao en Sint Maarten). It is worth noting that real estate in Sint Maarten is rarely if ever transacted in Guilders as most sellers prefer U.S. dollars or euros.

In practice, the US dollar is used so heavily that most businesses price directly in USD and accept it without a second thought. As a tourist, you'll rarely see guilder pricing at all. What this means for you:

• Nearly everything is priced in USD already (no mental math required)

• Both your villa and local vendors accept dollars directly.

• Credit cards work without issues.

Quick tip: If you do spot guilder pricing at a local shop or supermarket, divide by 1.79 to get the USD equivalent.

Credit Cards & ATMs

Which Cards Work Best ?

VISA and Mastercard are accepted almost everywhere on the island, restaurants, villa bookings, rental car agencies, excursions, and boutiques. American Express is less common but still accepted at many establishments.

A practical card strategy for the trip:

• Primary card: Visa or Mastercard for the widest acceptance.

• Secondary card: A backup in case your primary gets declined or flagged.

• Notify your bank: Let them know you're traveling to St. Martin so they don't freeze transactions.

• Skip the foreign transaction fee if you can: Many travel-focused cards waive this fee entirely.

Expect a foreign transaction fee of 1–3% on most US or EU cards, plus a $2–5 fee per ATM withdrawal. Some cards waive both for international travel; worth checking before you fly.

Finding ATMs

ATMs are readily available in the main towns and tourist areas, including:

• Airport: Princess Juliana International Airport (SXM)

• French side: Marigot (town center and marina), Orient Bay

• Dutch side: Philipsburg, Cole Bay, Simpson Bay

Most machines accept Visa and Mastercard, and daily withdrawal limits typically run $300–500 depending on your bank. Plan ahead rather than relying solely on ATMs, especially over weekends and if you're not sure where the nearest one is, your villa's front desk can point you in the right direction.

Exchange Rates & Where to Exchange Money

Current EUR/USD Rate

As of early September 2026, the euro is trading at roughly €1 = $1.16, though it moves daily with the broader forex market.

Best Places to Exchange

Because USD is so widely accepted, you don't need to convert cash into euros at all. If you're arriving with a different home currency and want cash on hand:

• ATMs on the island generally offer mid-market rates but charge withdrawal fees.

• Your home bank before departure often has the best rates with no surprise fees.

Quick tip: pull USD from an ATM at the airport on day one. Exchange counters in tourist zones almost always offer worse rates than your home bank or an island ATM.

Cash vs Card: When to use each

Cards give you no currency confusion, fraud protection, a locked-in exchange rate, and a clean receipt trail. Cash matters for small businesses that prefer it, and for tips (which land better in hand than on a bill).

Quick tip: Bring $200 in mixed denominations, mostly $20s and $10s.

Tipping Norms in St. Martin

Tipping is genuinely important here, service workers depend on it as a significant part of their income. Here's what's appropriate across the situations you're most likely to run into.

Restaurants & Bars

Some upscale restaurants add a 15% gratuity automatically, please check your bill before tipping again on top of it.

Villa Staff & Services

If you're renting through St. Martin Sotheby's Realty, here's the going rate for villa staff who make your stay run smoothly:

If you're staying a week or longer, a single lump-sum tip at the end for housekeeping or the chef is perfectly acceptable — and genuinely appreciated over piecemeal daily tips.

Other services

Tipping in Euros vs. USD

Regardless of the side, go with USD: local staff generally prefer it since they can use it island-wide.
