You’re standing at a colorful beach bar in Grenada or maybe a breezy dock in St. Kitts, reaching into your wallet to pay for a cold Carib beer. You see two prices. One is in "local" and one is in "US." If you’ve traveled much, your brain probably starts doing frantic mental math, trying to figure out if you're getting ripped off by a dynamic exchange rate. But here is the weird thing about the US dollar to Eastern Caribbean currency relationship: the math hasn't changed since the 1970s.
Seriously.
While the Euro swings wildly and the British Pound behaves like a rollercoaster, the Eastern Caribbean Dollar (XCD) is basically the US Dollar’s shadow. It’s pegged. It’s locked. It’s glued. If you want to understand how to move your money through the islands without losing a chunk of it to "tourist tax" or bank fees, you need to know how this rigid system actually functions on the ground.
The 2.70 Rule: How the US Dollar to Eastern Caribbean Exchange Works
Most people land in Antigua or St. Lucia and see the exchange rate quoted at 2.70. That is the official peg set by the Eastern Caribbean Central Bank (ECCB). Specifically, $1 USD equals $2.70 XCD. It has been that way since July 1976. Think about that for a second. In 1976, the Apple I computer was just being released, and yet this exchange rate has remained a constant through every global recession, hurricane, and geopolitical shift since.
But here is the catch.
If you go to a grocery store in Basseterre, they might give you a rate of 2.60 or 2.65. Is it a scam? Not exactly. While the official rate is 2.7169 for banks, businesses often shave off a few cents to cover their own costs of converting that US cash back into local currency at the bank later. If you use a credit card, you’ll usually get much closer to that 2.70 mark, minus whatever your bank charges for foreign transactions.
I've seen travelers get genuinely frustrated when a taxi driver asks for $20 USD or $50 XCD. If you do the math ($20 times 2.70), it should be $54 XCD. The driver is actually giving you a slight "discount" for paying in USD because US currency is essentially the "gold standard" of the region. It’s highly liquid. Everyone wants it.

Why the Peg Matters for Your Wallet
The Eastern Caribbean Central Bank manages the currency for eight territories: Anguilla, Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines. Because they all share this single currency pegged to the dollar, it creates a massive bubble of price stability.
You don't have to worry about "hyper-inflation" mid-vacation.
However, because the US dollar to Eastern Caribbean rate is fixed, the cost of living in these islands moves in lockstep with US inflation. If prices go up in Miami, they go up in Castries. Almost everything in the Eastern Caribbean—from the fuel powering the ferries to the boxes of cereal on the shelves—is imported. When you pay in USD, you are participating in a massive import-export loop that keeps these island economies afloat.
Cash vs. Card: The Hidden Costs of Convenience
Don't just rely on the 2.70 number.
Banks in the islands, like Republic Bank or CIBC FirstCaribbean, will often charge a small commission. If you walk into a branch with a stack of Benjamins, you won't walk out with exactly 270 dollars for every 100. You'll likely get closer to 267 or 268 after the fee.
Honestly, the best way to handle money is often the ATM.
When you use an ATM in the islands, you are withdrawing XCD. Your home bank does the conversion. If you have a travel-friendly card—think Charles Schwab or a high-end Chase Sapphire—they often reimburse the ATM fees and give you the mid-market rate. It beats carrying a thick envelope of cash that you might lose on a catamaran trip.
The "Change" Trap
Here is a pro tip that most travel blogs miss.
If you pay in US Dollars at a local shop, you will almost always get your change back in Eastern Caribbean Dollars. This is where the math gets messy. If you buy a $10 USD souvenir with a $20 USD bill, the shopkeeper might give you back $27 XCD.
You’ve basically just performed a currency exchange without meaning to.
If you're leaving the islands the next day, those colorful XCD bills are going to be hard to spend back home. Most US banks won't even look at them, or if they do, they’ll give you a terrible rate. Try to "burn" your local currency on your last day for things like airport snacks or tips, so you aren't stuck with "monopoly money" in your drawer for the next five years.
The Role of the ECCB in Maintaining Stability
You might wonder how a group of small island nations keeps a currency so stable. It's thanks to the Eastern Caribbean Central Bank, based in St. Kitts. They maintain a foreign exchange reserve that covers almost 100% of the currency in circulation.

It’s a conservative, "currency board" style of management.
Unlike the US Federal Reserve, which can print money to stimulate the economy, the ECCB is much more restricted. This is why you don't see the XCD crashing. It’s backed by actual US dollars held in reserve. For a traveler or an expat, this means the US dollar to Eastern Caribbean rate is one of the most predictable financial metrics in the world.
Is it perfect? No. Some economists argue that the peg makes island exports too expensive when the US dollar is strong. If the USD climbs against the Euro, suddenly a vacation to St. Lucia becomes much more expensive for a French tourist than a trip to a non-pegged neighbor. But for those of us using greenbacks, it's a blessing of simplicity.
Real-World Price Comparisons
Let's look at what your money actually buys.
- A standard meal at a local "roti" shop: $15 - $25 XCD ($5.50 - $9.25 USD).
- A high-end dinner at a resort: $150+ XCD ($55+ USD).
- Local bus fare (the colorful vans): $2.50 - $5 XCD (under $2 USD).
- A gallon of gas: Roughly $13 - $15 XCD ($5 USD).
Prices vary by island. Antigua and St. Barts (which uses the Euro, don't get confused!) are generally pricier than, say, Dominica or St. Vincent. Dominica is rugged and less "resort-heavy," so your US dollar to Eastern Caribbean conversion will feel like it goes significantly further there.
Digital Assets and the Future: DCash
Interestingly, the Eastern Caribbean was one of the first regions to experiment with a central bank digital currency (CBDC) called DCash. It’s basically a digital version of the XCD. While it hasn't completely replaced physical cash, it shows that the region is trying to modernize the way we think about the US dollar to Eastern Caribbean link.
For the average visitor, you don't need to worry about DCash yet.
Just stick to a mix of small US bills (ones, fives, and tens are king) and a solid credit card. Why small bills? Because trying to break a $100 USD bill at a roadside fruit stand is a great way to make an enemy of a vendor who doesn't have $250 XCD in change to give you.

Avoid the Airport Exchange Desks
This applies everywhere, but especially in the Caribbean. The exchange booths at the V.C. Bird International Airport or Hewanorra will give you the worst rates. They know you're tired, hot, and just want to get to your hotel. Wait until you get to an ATM or just pay the taxi driver in USD. Almost every taxi driver in the OECS (Organization of Eastern Caribbean States) accepts US dollars gladly.
Practical Steps for Your Trip
To make the most of your money, follow this simple workflow:
- Notify your bank that you'll be in the Eastern Caribbean. If they see a charge in St. Kitts and then one in Grenada, they might freeze your card thinking it's fraud.
- Bring $200 in small US bills. Use these for tips and small purchases where credit cards aren't accepted.
- Use an ATM on day one to get about $300 XCD. This ensures you have local currency for the "local" price, which is often slightly cheaper than the "tourist" USD price.
- Always choose "Local Currency" if a credit card machine asks if you want to be charged in USD or XCD. This is called Dynamic Currency Conversion, and it's almost always a scam. Let your home bank do the conversion; they’ll give you a better rate than the merchant's machine.
- Check your change. If you pay in USD, make sure the change you get back in XCD is calculated at least at a 2.60 rate. Most locals are honest, but it never hurts to do a quick mental check.
The relationship between the US dollar to Eastern Caribbean currency is a rare example of long-term financial stability. It makes the islands one of the easiest places for Americans or those with US dollar accounts to travel. You get the exotic feel of a foreign currency with the safety net of a fixed exchange rate.
Just remember: 2.70 is the magic number. Keep that in your head, and you'll never feel lost when the bill arrives.
Before you head out, download an offline currency converter app. While the rate doesn't change, having a quick calculator helps when you're trying to figure out if that hand-carved mahogany bowl is worth the $80 XCD price tag while you're standing in the middle of a sun-drenched market. Most of the time, the answer is yes.
