Money in the Caribbean is usually a guessing game of floating rates and daily fluctuations. Not so in George Town. If you’re looking at cayman currency to usd conversions, you’ve probably noticed something weird. The rate doesn’t move. It hasn't moved since 1974.
That’s a long time for a relationship to stay exactly the same.
The Cayman Islands Dollar (KYD) is pegged to the US Dollar. It’s a rigid, unwavering marriage between two currencies that simplifies life for offshore bankers but often confuses the hell out of tourists getting off a cruise ship. Most people assume they’ll get a one-to-one swap. They won't.
Why the Cayman Currency to USD Rate is Always 1.20
Let's get the math out of the way immediately. One Cayman Islands Dollar is worth exactly $1.20 USD.

Always.
This isn't like the Euro or the Pound where you check an app every morning to see if you can afford that extra espresso. The Cayman Islands Monetary Authority (CIMA) keeps this peg locked in. It provides a level of stability that has turned these three tiny islands into the world's sixth-largest financial center. But there’s a catch for the average person.
When you walk into a shop on Seven Mile Beach, you’ll see prices in KYD. If you hand over US cash, the shopkeeper isn't going to give you that $1.20 rate. Most local businesses use a standard "tourist rate" of 1.25. Basically, they charge you a small convenience fee for not using the local legal tender. It's a bit of a hidden tax on the unprepared.
It feels slightly unfair until you realize the logistical headache of handling two currencies in a single cash register.
The psychology of the "Expensive" dollar
It’s a psychological trip. Usually, when Americans travel, their dollar feels "strong." In Mexico or South East Asia, a handful of greenbacks goes a long way. In the Caymans, your money feels smaller. You hand over a twenty-dollar bill and get back a ten and some change in colorful KYD notes.
It’s one of the few places on earth where the US Dollar is the "weak" currency in the room.
The 1971 Breakup and the Birth of the KYD
Before 1972, the Cayman Islands used the Jamaican Dollar. It made sense; they were administratively linked for years. But when Jamaica decided to go its own way, the Caymans had a choice. They could have stayed with Jamaica, but they saw the writing on the wall regarding inflation and economic shifts.
Instead, they minted their own money.

By 1974, they pinned it to the US Dollar. Since then, the exchange rate has been the bedrock of their economy. It attracts hedge funds. It attracts private equity. Why? Because there’s zero "currency risk." If you move a billion dollars into a Cayman bank today, you know exactly what it’s worth in US terms tomorrow.
Actually, the islands don't even have a central bank in the traditional sense. CIMA acts more like a currency board. For every KYD in circulation, they hold a corresponding amount of US assets. It’s a hard-asset backing that many larger nations have long since abandoned.
Don't get burned at the ATM
Here is a mistake I see constantly.
A traveler goes to an ATM in Camana Bay. They see the option for the ATM to do the "conversion" for them. Never do this. This is called Dynamic Currency Conversion (DCC). The bank is essentially offering to do the cayman currency to usd math for you at a terrible rate—often 5% to 7% worse than what your home bank would charge.
Always choose to be charged in the "Local Currency" (KYD). Your bank at home will handle the conversion using the interbank rate, which is almost always closer to that official $1.20 mark.
Real-World Math: A Lunch on the Waterfront
Let’s look at a real scenario. You’re sitting at a restaurant. The bill comes to 40 KYD.
If you pay in US cash at the standard 1.25 retail rate, you owe $50.00 USD.
If you pay with a credit card that has no foreign transaction fees, the bank processes it at the 1.20 rate. You pay $48.00 USD.
Two dollars might not seem like much. But over a week of dinners, jet ski rentals, and Stingray City tours, you’re looking at hundreds of dollars in "lazy tax" just for using the wrong paper. Honestly, it adds up faster than you'd think in a place as pricey as Grand Cayman.

The Legal Tender Loophole
Technically, the US Dollar is not legal tender in the Cayman Islands. However, everyone accepts it. It’s a "de facto" dual-currency economy.
There is one quirk you need to know: You will almost always get your change back in Cayman Islands Dollars.
This is how the islands keep their currency circulating. If you pay for a $5 beer with a $20 US bill, expect a handful of KYD in return. If you're leaving the island the next day, those KYD notes are basically souvenirs. US banks hate small-scale currency exchange. Trying to swap 15 KYD back to USD at your local Chase branch in Ohio is a nightmare, and they’ll likely charge you a fee that wipes out the value of the money anyway.
My advice? Use your KYD for your last meal at the airport or tip the housekeeping staff with it. Don't bring it home expecting to spend it at a Starbucks.
Why the Peg Won't Break
Some economists argue that a fixed peg is dangerous. Look at what happened to Argentina or Switzerland in the past when they tried to hold a rate against market forces.
But the Cayman Islands are different.
Because they are a tax-neutral jurisdiction with a massive financial services sector, they need that 1.20 link. It’s their primary selling point. If the KYD started floating, the uncertainty would drive the banking industry to the British Virgin Islands or Bermuda faster than a Category 5 hurricane.
The government is incentivized to maintain this at all costs. They have enough US reserves to buy back every single KYD in existence if they had to. It’s a fortress of a currency, even if it makes your Caribbean vacation feel 20% more expensive than you planned.
Common Misconceptions
- "Is the Cayman Dollar the same as the Bahamian Dollar?" No. The Bahamas is pegged 1-to-1. Cayman is 1-to-1.20. It's the most valuable currency in the Caribbean.
- "Can I use my credit card everywhere?" Mostly, yes. But some small vendors in East End or North Side might prefer cash.
- "Should I exchange money at the airport?" Absolutely not. The kiosks at MIA or JFK will give you a predatory rate. Wait until you land and just use a card or a local ATM.
Moving Forward: Your Actionable Strategy
If you're planning a trip or doing business in the islands, don't just wing the cayman currency to usd conversion.
First, get a credit card with zero foreign transaction fees. This is the single biggest money-saver in the Caymans. Cards like the Chase Sapphire Preferred or any Capital One Venture card will give you the 1.20 rate without tacking on that 3% "international" fee.
Second, do the "Divide by 4, Add it on" trick. If you’re looking at a menu in KYD and want to know the US price quickly, divide the price by 4 and add that to the total.
- Example: 20 KYD.
- 20 divided by 4 is 5.
- 20 + 5 = 25.
- The meal is roughly $25 USD.
Third, carry a small amount of US cash for tips, but use plastic for everything else. Tipping is standard at 15-20%, and most bills include an automatic "service charge." Check your receipt before you double-tip; it’s a common mistake tourists make when they're already confused by the exchange rate.
Understand the peg, avoid the retail 1.25 rate when possible, and stop worrying about the daily fluctuations. In the Cayman Islands, the rate you see today is the same one you'll see a decade from now.
