How Exchange Rates Work: Mid-Market Rates, Margins and the AED–INR Rate
What the 'real' exchange rate is, how banks and exchange houses make money on the spread, why the dirham is pegged, and how to get a better rate on remittances.

Search "AED to INR" and you get one number. Send money home and you get a different, worse one. The gap is how the money-transfer business makes its profit.
The mid-market rate
The mid-market rate is the midpoint between the price banks buy and sell a currency at in wholesale markets. It's the fairest reference rate — and it's what the free Currency Converter shows, updated daily for 160+ currencies.
Where the cost hides
| Cost | What it is |
|---|---|
| Exchange-rate margin | The provider gives you a worse rate than mid-market (often 0.5–3%) |
| Transfer fee | A fixed charge per transfer |
| Receiving fees | Charged by the beneficiary's bank, sometimes |
A "zero-fee" transfer with a 2% rate margin costs more than a AED 15 fee at a near-mid-market rate. Always compare the amount received.
The dirham peg
The UAE dirham has been pegged to the US dollar at 3.6725 AED per USD since 1997. So AED–INR moves almost exactly with USD–INR. The same applies to the Saudi riyal (3.75), Omani rial, Qatari riyal and Bahraini dinar, which are also dollar-pegged. The Kuwaiti dinar is pegged to an undisclosed basket.
Getting a better rate on remittances
- Compare total received, not the headline rate.
- Send larger, less frequent amounts if fees are fixed.
- Use app-based providers or exchange-house apps, which often beat walk-in rates.
- Watch the trend — the converter lets you compare several currencies at once.
- Avoid card currency conversion (DCC) when paying abroad — choose the local currency.
For businesses
Foreign-currency invoices create two numbers: the invoice amount and its value in your reporting currency. For UAE VAT, the FTA requires conversion at the Central Bank of the UAE rate for the date of supply — not a converter's reference rate. Pyalm Books handles multi-currency invoicing and converts at the right rate for VAT reporting.
