The DCC Trap Abroad

What is dynamic currency conversion?

You are in Dubai. The bill is 500 dirhams. The terminal offers you a second figure in rupees and asks you to pick.

Pick dirhams and the amount travels to Visa or Mastercard. The network converts it at its own wholesale rate. Your bank then adds its markup, which is set out in your card terms.

Pick rupees and the shop’s payment provider does the conversion right there. It sets the rate. It keeps a margin, and it shares part of that margin with the merchant. Only then does the amount reach your bank.

What each choice costs you

Markup figures are from our card data, as of 15 August 2026. GST at 18% is applied to the markup.

Why the rupee price on the screen looks safer

It looks safer because it is certain. You see the exact rupee figure before you tap. No surprise on the statement.

That certainty is what you are paying for, and the price is not shown next to it. The terminal does not display the network rate you would have got. It shows one rate, its own, and asks you to accept.

The fix takes ten seconds. Open a rate app before you pay. Our live exchange rates and currency converter both give you the mid-market number. Compare it against the terminal’s rate. If the gap is more than your card’s own markup, decline.

Does your bank still add its markup if you paid in rupees?

Often, yes. That is the part almost nobody checks.

The transaction was still acquired outside India. Several Indian issuers treat any such transaction as a foreign one, whatever currency it was billed in, and apply their markup anyway. Others do not.

There is no way to reason this out. It is written in your card’s Most Important Terms and Conditions. Read that one line before you travel. If both charges apply, DCC has cost you the provider’s margin plus your bank’s markup on the same purchase.

Where DCC shows up

It is not only card machines in shops. Watch for it in four places.

• Shop and restaurant terminals, as a currency choice before you tap.
• Foreign ATMs, usually as a screen offering a “guaranteed rate in INR”. Decline it, then take the cash.
• Airline, hotel and booking websites that detect your card is Indian and quote in rupees.
• Car hire desks and hotel checkouts, where the staff may pick for you without asking.

At an ATM the wording is designed to sound protective. “With conversion” or “guaranteed rate” both mean DCC. Choose “without conversion” or “continue in local currency”.

Is there an Indian rule against DCC?

No, and it is worth being clear about that. We read the RBI’s Master Direction on credit and debit cards. It does not deal with currency conversion at all. On international cards it simply defers to other RBI instructions and to FEMA.

So no Indian regulator caps the margin a foreign payment provider can charge you. Your protection is the choice on the screen, and nothing else.

One right does apply. Under paragraph 10(b) of that direction, if you dispute a bill, your card issuer must give you an explanation, and documents where relevant, within 30 days of your complaint. But a DCC rate you accepted on a terminal is not a billing error. You agreed to it. That is exactly why the choice matters at the moment you make it.
