The UAE dirham (AED) is the official currency of the United Arab Emirates, and it is the currency used in Dubai, Abu Dhabi and the other five emirates. It is issued by the Central Bank of the UAE, divides into 100 fils, and has been pegged to the U.S. dollar since 1997 at 1 USD = 3.6725 AED. Locally, prices are often written as “Dhs” or “Dh”; AED is the ISO 4217 code used by banks and trading platforms.

What Is the UAE Dirham (AED)?

The dirham replaced the currencies that circulated in the emirates before federation, chiefly the Qatar and Dubai riyal, when it launched in 1973. Dubai has had no separate currency of its own since then.

Banknotes come in denominations of 5, 10, 20, 50, 100, 200, 500 and 1,000 dirhams. Coins exist in 1, 25 and 50 fils alongside a 1 dirham coin, though coins worth less than 10 fils rarely change hands.

How the UAE Dirham Works

A currency peg means the central bank commits to keeping the exchange rate with an anchor currency at a set level. For the dirham, that anchor is the U.S. dollar and the level is 3.6725. To hold it, the Central Bank of the UAE stands ready to exchange dirhams for dollars at that rate, which requires a large stock of dollar reserves. A strong current account, which the UAE has run as a surplus, keeps those reserves supplied.

Market quotes for USD/AED trade in a very narrow band around the central rate. What a traveler or business actually receives at a bank or exchange house will differ slightly, because the provider adds a spread or fee on top of the official figure.

Interpreting the Dirham’s Exchange Rates

The peg answers a common question: does the dirham move against the dollar differently from other currencies? Yes. Most major currencies float, so EUR/USD or USD/JPY change every second. AED/USD essentially does not. Against everything else, the dirham inherits the dollar’s moves:

AED cross rate = (foreign currency per USD) ÷ 3.6725

If the dollar strengthens 2% against the Korean won, the dirham strengthens roughly 2% against the won too. This also settles the question of whether the AED is “stronger” than the won. One dirham buys many won, but a higher unit value only reflects where each currency started, not economic strength. What matters for a holder is how the rate changes, and for AED that change is the dollar’s change.

Why the UAE Dirham Is Pegged to the Dollar

Oil has long been central to the UAE economy, and oil is priced in dollars. Fixing the dirham to the dollar keeps export revenue predictable in local terms and removes exchange rate risk from a large share of trade and investment. Importers, foreign investors and the many residents who send earnings abroad can plan without worrying that the dirham will swing against the dollar.

The dirham is not alone in this. Other Gulf Cooperation Council members also tie their currencies to the dollar; the Saudi riyal, for example, is pegged at 3.75 per dollar.

Example of Converting Dirhams

Hypothetical example, using the official peg and ignoring provider spreads:

• USD to AED: 100 USD × 3.6725 = 367.25 AED. 15,000 USD × 3.6725 = 55,087.50 AED.
• AED to USD: 1,000 AED ÷ 3.6725 = about 272.29 USD.
• AED to EUR: suppose EUR/USD were 1.10. Then 1 EUR = 1.10 × 3.6725 = 4.03975 AED, so 1,000 AED ≈ 247.54 EUR. If EUR/USD then rose to 1.15 with the peg unchanged, 1 EUR would cost 4.2234 AED and the same 1,000 AED would buy only about 236.78 EUR.

The euro conversion changed only because the dollar moved. The dirham side of the calculation stayed constant. For a company with dollar costs and dirham revenue, that constant leg means one less exposure to hedge; a euro or rupee exposure still needs managing.

Limitations of the Dollar Peg

Imported monetary policy. To keep the peg credible, the UAE generally has to follow U.S. interest rate decisions, even when local conditions might call for something different. Dirham borrowing costs therefore tend to track the Federal Reserve rather than the domestic economy.

Oil price stress. The peg can conflict with government finances. When oil prices fell sharply in 2014 to 2016, revenue dropped, and some Gulf states faced discussion of devaluing their currencies. A weaker local currency would have turned each dollar of oil sales into more local money. The UAE kept the 3.6725 rate, but the episode showed that a peg is a policy choice backed by reserves, not a permanent law of the market.

Little to trade. For forex traders, USD/AED offers almost no price movement to speculate on, and AED crosses are effectively dollar crosses with an extra conversion step.

Distinctions People Confuse

• AED vs. dirham vs. Dhs: the same currency. AED is the code, dirham the name, Dhs or Dh the local price abbreviation.
• UAE dirham vs. Moroccan dirham: different currencies. Morocco’s dirham (MAD) is issued by Morocco’s central bank and is not pegged solely to the dollar.
• Dubai vs. UAE: Dubai is one emirate. Abu Dhabi, Sharjah and the rest use the same dirham.
• Dirham vs. riyal: the Saudi and Qatari riyals are separate currencies with their own pegs.

The Bottom Line

Travelers, residents sending money abroad, and businesses with dollar costs benefit most from the dirham's fixed dollar rate, since that leg of any conversion stays constant. Exposure to the euro, rupee and other currencies still follows the dollar's swings and needs managing. Forex traders will find little movement in USD/AED, and the 2014 to 2016 oil slump showed the peg rests on policy and reserves.
