Understanding Exchange Rates: A Complete Guide
Learn how exchange rates work, what affects them, and how to read currency pair quotes like a pro.
What is an Exchange Rate?
An exchange rate is the price of one currency expressed in terms of another currency. For example, if the AED to INR exchange rate is 22.850, it means 1 UAE Dirham equals 22.850 Indian Rupees.
Exchange rates are constantly changing based on supply and demand in the global foreign exchange market (forex). This market operates 24 hours a day, 5 days a week, and is the largest financial market in the world with over $7 trillion traded daily.
How to Read Currency Pairs
Currency pairs are always quoted in a specific format: BASE/QUOTE. The first currency (base) is what you're converting FROM, and the second currency (quote) is what you're converting TO.
Base Currency: USD (US Dollar)
Quote Currency: INR (Indian Rupee)
Meaning: 1 USD = 83.450 INR

Types of Exchange Rates
1. Mid-Market Rate (Interbank Rate)
The mid-market rate is the midpoint between the buy and sell prices of two currencies in the wholesale currency markets. This is the "real" exchange rate you see on financial news sites and is what banks use when trading with each other. It's also the rate we display on INR Daily.
2. Consumer Rate (Retail Rate)
This is the rate you actually get when exchanging money through banks, money transfer services, or currency exchange offices. It includes a markup (margin) on top of the mid-market rate to cover the provider's costs and profit.
3. Tourist Rate
The rate offered at airport currency exchanges and hotels, typically the least favorable for consumers due to convenience premiums and high overhead costs.
What Affects Exchange Rates?
GDP growth, inflation rates, employment data, and trade balances all influence currency strength. Strong economic data typically strengthens a currency, while weak data weakens it.
Higher interest rates offer better returns on investments denominated in that currency, attracting foreign capital and increasing demand for the currency.
Countries with stable governments and predictable policies attract more foreign investment, strengthening their currency. Political uncertainty can weaken currencies.
Investor psychology and perception can drive short-term currency movements. News events, rumors, and speculation all play a role.
Like any market, if more people want to buy a currency than sell it, the price (exchange rate) goes up. International trade, tourism, and investment all affect supply and demand.
Why Do Rates Change Daily?
Exchange rates fluctuate constantly because the factors affecting them are constantly changing. Economic data is released regularly, central banks adjust interest rates, political events occur, and market sentiment shifts. Even within a single day, rates can move significantly based on news and trading activity.
For currencies like the AED and SAR, which are pegged to the US Dollar, their INR exchange rate primarily follows the USD-INR rate. This is why tracking USD movements is crucial when monitoring AED-INR or SAR-INR rates.
How to Get the Best Exchange Rate
Monitor Rates Over Time
Use our rates directory to check historical trends. Look at 30-day and 90-day charts to identify patterns and favorable timing.
Set Rate Alerts
Don't constantly check rates manually. Set up free rate alerts to notify you when your target rate is reached.
Compare Multiple Providers
Different money transfer services offer different rates and fees. Use our comparison tool to find the best deal for your specific transfer amount.
Avoid Airport Exchanges
Airport currency exchanges typically offer the worst rates due to convenience premiums. Plan ahead and use online transfer services instead.
Consider Timing
Market hours matter. Liquidity is highest during European and US trading hours, which can lead to better rates. Weekend rates are often less favorable.
Common Exchange Rate Mistakes to Avoid
- Only looking at transfer fees: A low fee doesn't mean a good deal if the exchange rate markup is high
- Using credit cards abroad: Credit card companies typically add 2-3% foreign transaction fees plus unfavorable exchange rates
- Accepting dynamic currency conversion: When paying abroad, always choose to pay in the local currency, not your home currency
- Not planning ahead: Last-minute transfers often mean accepting whatever rate is available
- Ignoring the total cost: Always calculate how much INR your recipient will actually receive after all fees and rate markups
Pro Tip
The exchange rate you see advertised is rarely the rate you actually get. Always ask "How much INR will my recipient receive for [amount] [currency]?" This total amount is what matters, not the advertised rate or fee.
Understanding Currency Pegs
Some currencies, like the AED and SAR, are "pegged" to the US Dollar at a fixed rate. The UAE Dirham is pegged at 3.67 AED = 1 USD, and the Saudi Riyal is pegged at 3.75 SAR = 1 USD. This means these currencies maintain a stable relationship with the USD.
When you're tracking AED-INR or SAR-INR rates, you're essentially tracking how the INR moves against the USD. This is why understanding USD-INR dynamics is crucial for anyone sending money from the Gulf region to India.
