What is a currency peg?
A currency peg is a fixed exchange rate a central bank sets between its currency and another, usually the US dollar. The UAE dirham has been pegged at AED 3.6725 per US dollar since 1997, so the USDT to AED rate barely moves — only the desk's spread changes.

How a currency peg works
The central bank commits to buy and sell its own currency against the anchor currency at one fixed rate, using its foreign-exchange reserves. The Central Bank of the UAE has held the dirham at AED 3.6725 per US dollar since November 1997 and intervenes in the foreign-exchange market at that rate, so USD/AED does not trade freely the way EUR/USD does.
A peg is a policy commitment, not a physical law. The Swiss National Bank dropped its euro floor without warning in January 2015. The AED peg has held since 1997, and as of September 2026 the CBUAE still maintains the 3.6725 rate.
Why it matters when selling USDT in the UAE
Because USDT targets one US dollar and the dirham is fixed to the dollar, the USDT to AED rate sits near 3.67 and the only real variable in a quote is the desk's spread, published on the pricing section of the main page. A desk quoting meaningfully better than 3.6725 is promising better-than-arithmetic, and the missing money usually appears in the settlement leg. A USDT to AED trade also carries a second peg, USDT's own, which rests on Tether's reserves and arbitrage by market makers; any USDT premium or discount to the dollar shows up in the proceeds on top of the spread.
Illustrative example
A ticket of 250,000 USDT sold at the pegged rate: gross 250,000 × 3.6725 = AED 918,125; at a 0.25% spread the cost is AED 2,295, so AED 915,830 reaches the bank account, by UAEFTS the same business day once the account is approved.
FAQ
Is the dirham always exactly 3.6725 per dollar?
The official parity has been AED 3.6725 per US dollar since 1997, and wholesale USD/AED exchanges happen at that rate. Retail counters and card transactions apply a small margin on top, so the rate you see as a consumer is close to 3.6725, not exactly it.
Does the AED peg mean 1 USDT equals AED 3.6725?
Approximately. USDT targets one US dollar and the dirham is fixed to the dollar, so USDT/AED sits near 3.6725. Your final rate differs by the desk's spread plus any small USDT premium or discount to the dollar that day.
Could the UAE ever change or drop the peg?
A peg is a policy choice and can in principle be changed, and any change would be announced by the Central Bank of the UAE. The peg has held since November 1997; as of September 2026 there is no announced change. Re-check before a very large trade.
Is a currency peg the same thing as a stablecoin peg?
No. A currency peg is defended by a central bank buying and selling with foreign-exchange reserves. A stablecoin peg like USDT's relies on the issuer's reserves and arbitrage by market makers. Both are commitments rather than guarantees, and both can break.
