The Two-Wallet Rule: Caribbean Cash, Cards and Currency for UK Travellers

Caribbean spending has a way of feeling invisible. A rum punch here, a taxi to the beach there, a water taxi to a sandbar you'll never forget. Then you open your banking app and discover that three small purchases have attracted fees, one ATM has charged you twice, and a card machine has helpfully converted your lunch into pounds at a rate that suits the machine rather than you.

At West Indies Escapes, we'd rather you spent your holiday money on a boat trip than on avoidable bank charges. So here's a practical, UK-facing way to think about cash and cards across the islands — without pretending there's one simple answer for every destination.

First, work out which dollar you're dealing with

The Caribbean is not a single currency zone. Some islands quote in US dollars almost as a second language. Others use the East Caribbean dollar, which is pegged to the US dollar at roughly EC$2.70 to US$1. Barbados has its own dollar, pegged at two to one against the US dollar. Jamaica uses Jamaican dollars, Trinidad uses Trinidad and Tobago dollars, and the Bahamas uses a Bahamian dollar that sits at par with the US dollar.

Hotels often quote in US dollars because it feels familiar to international guests. That does not mean the taxi driver, beach bar or local bus will do the same. If a price is quoted in US dollars but your change comes back in East Caribbean dollars, check the rate before you hand over notes. And don't assume that every mention of 'dollars' means the American kind.

Cards are useful, but they are not universal

In hotels, supermarkets, upscale restaurants and larger shops, Visa and Mastercard are generally accepted. Contactless payments have become more common in 2026, but they are still patchy outside tourist centres. American Express is much less welcome than in the UK, and small guesthouses may add a card surcharge or quietly prefer cash.

Carry at least two cards: a debit card for ATM withdrawals and a credit card for purchases, ideally both with low or no foreign transaction fees. UK banks and app-based accounts have made this easier, but check the small print before you fly. A card that looks fee-free at home can still charge for overseas cash withdrawals or add a mark-up on the exchange rate.

Use your debit card for cash and your credit card for spending where possible. Avoid using a credit card at an ATM unless it is a genuine emergency — interest on cash advances usually starts immediately, and fees can stack up quickly.

The ATM rules that save real money

Use ATMs attached to banks, ideally inside a branch, shopping centre or airport. Standalone machines on the street are more likely to be unreliable or expensive. Withdraw larger amounts less often to reduce fixed fees, but don't carry a fortune around with you.

Check both sides of the charge: your UK bank's fee and the local operator's fee. Some ATMs dispense US dollars, others local currency, and a few offer both. Take a moment to read the screen rather than jabbing at the first button.

If the machine offers to convert your withdrawal into pounds sterling, decline. That is dynamic currency conversion, and it usually comes with a poor exchange rate. Choose the local currency and let your bank do the conversion. The same rule applies at card terminals in shops and restaurants: always pay in the local currency, not in GBP.

Cash still matters — especially away from the hotel

Beach bars, taxis, local buses, markets, small shops and tips are where cash earns its keep. Many taxi drivers will not take cards, and a rum shack with a hand-painted sign may have no terminal at all. Budget a daily cash float for the small stuff, and keep it separate from your main card wallet.

On islands that use East Caribbean dollars, carry some EC dollars for small purchases. US dollars are widely accepted, but the exchange rate offered by a beach vendor may not be generous. Small notes are your friend. Breaking a large US dollar bill for a bottle of water can be awkward, and some places will simply say they have no change.

Before you leave the UK, order a small amount of US dollars for arrival day — enough for a taxi, a snack and a tip. Don't overbuy, though. On islands using East Caribbean dollars or local currencies, you'll usually get a better deal by spending in the local money once you're there.

Tipping without guesswork

Tipping norms vary by island and by venue. In many restaurants, a service charge of around 10 to 15 per cent is already added. Check the bill before adding more. If service is not included, 10 to 15 per cent is a reasonable guide for good service. Taxi drivers are often tipped by rounding up or adding around 10 per cent. Housekeeping staff appreciate a small daily amount left in local currency, and porters usually expect a small note per bag.

A handful of US dollar bills is useful for tips, but local currency is often more welcome. Keep small notes accessible so you're not fumbling in a beach bag while the taxi meter — or the driver's patience — runs on.

A simple two-wallet system

Think of your holiday money as two wallets. One holds your cards and stays in the hotel safe when you don't need it. The other holds a sensible daily amount of cash, split between a purse or pocket and a bag. Never carry everything at once, and keep a backup card separate from your main one.

Before you fly, check your bank's overseas fees, make sure your PIN works abroad, and save your bank's emergency number offline. Tell your bank you're travelling if it still asks — many UK banks no longer require it, but it's worth a quick check. And if a card terminal or ATM offers to charge you in pounds, politely choose the local currency instead. Your future self, sipping something cold on a veranda, will thank you.
