Getting foreign currency at the best rates can save you thousands on international trips. This guide covers where to buy forex, RBI limits, forex cards vs cash, and smart tips for Indian travellers heading abroad.

Ways to Carry Foreign Currency

Method	Exchange Rate	Convenience	Safety	Best For
Forex Card	Best rates	High	Very safe	Primary spending method
Foreign Cash	Moderate	High	Risk of theft	Tips, small vendors, emergencies
International Debit Card	Bank rate + markup	High	Safe	ATM withdrawals abroad
Credit Card	Visa/MC rate + 2-3.5% markup	High	Safe	Hotels, shopping, restaurants
Traveller's Cheques	Moderate	Low (declining acceptance)	Very safe	Not recommended anymore

Recommended mix: Carry 70-80% on a forex card, 15-20% as foreign cash, and keep your credit card as backup. This gives you the best rates, convenience, and emergency fallback.

Money-Saving Tips

Buy forex 2-3 days before travel — Avoid last-minute airport purchases. Rates are 3-5% worse at airports
Compare rates online — Use BookMyForex, ExTravelMoney to compare rates from multiple dealers
Use forex card for most spending — Better rates than credit cards, and the rate is locked when you load
Carry small cash for tips/vendors — Many small vendors, taxis, and tip situations require cash
Decline Dynamic Currency Conversion — When paying by card abroad, always choose to pay in LOCAL currency, not INR. DCC rates are terrible
Use zero-forex credit cards — Cards like Niyo, Fi, IDFC First, or travel-specific cards charge 0% forex markup
Buy leftover currency back — Don't waste remaining foreign cash. Sell it back through the same dealer or online platform
Track exchange rates — Apps like XE Currency show live rates. Buy when the INR is strong

Frequently Asked Questions

How much foreign currency can I carry from India?

Under RBI rules, you can carry up to $3,000 equivalent as foreign cash. Amounts above this must be in non-cash form (forex card, demand draft). The total forex you can take per financial year is $250,000 under the Liberalised Remittance Scheme (LRS). You must declare amounts over $5,000 in cash to customs.

Is a forex card better than carrying cash?

Yes, forex cards are generally better — they offer better exchange rates (0-2% markup vs 3-5% at airport counters), are safer (PIN protected, can be blocked if lost), and allow online reloading. Carry a small amount of cash (equivalent of Rs 5,000-10,000) for tips and small vendors, and use forex card for everything else.

Where do I get the best forex rates?

Online forex comparison platforms (BookMyForex, ExTravelMoney) consistently offer the best rates as they aggregate multiple dealers. Banks offer decent rates but with slightly higher markup. Airport forex counters offer the worst rates — avoid them except for emergencies. Buy forex 2-3 days before travel for the best rates.

Should I buy forex in India or at the destination?

Generally, buy forex in India before departure. Rates are usually better, and you avoid the hassle of finding exchange counters at your destination. Exception: For some currencies like Thai Baht or Indonesian Rupiah, exchanging US Dollars at the destination may give better rates than converting directly from INR in India.

What is Dynamic Currency Conversion and why should I avoid it?

DCC is when a foreign merchant offers to charge your card in INR instead of their local currency. Always decline this and choose local currency. DCC uses inflated exchange rates set by the merchant, typically 3-7% worse than your card network rate. You save money by paying in local currency and letting your card issuer handle the conversion.
