What is slippage?
Slippage is the difference between the price you expect when you place a trade and the price you actually get. On an exchange it comes from thin order books and fast markets; at an OTC desk the quoted price is the executed price, so slippage does not occur.
KEY FACTS
| Definition | Expected price minus the price you actually get |
|---|---|
| Where it appears | Exchange order books, thin or fast-moving markets |
| At an OTC desk | None — one quoted price covers the whole ticket |
| Worked example below | AED 10,100 slippage on a 2,000,000 USDT market sale |
| Meridian spread | 0.08%–0.40% by ticket size, as of September 2026 |

Where does slippage come from?
Slippage on an exchange comes from the order book: a market order fills against whatever limit orders are resting there, level by level. If your order is larger than the top level, it walks down the book and each level fills worse than the last — the standard story we hear from clients who tried selling USDT in Dubai on an exchange first.
Two further forces add to it. The market can move in the seconds between your decision and the fill, and a large order can be executed in parts minutes apart, each at its own price. The exchange shows you the average only after the fact.
A worked example: selling 2,000,000 USDT
Slippage is easiest to see in numbers. Take an illustrative sale of 2,000,000 USDT into AED on an exchange — the dirham has been pegged to the US dollar at 3.6725 since 1997, and why the USDT/AED rate sits at 3.67 explains what that means in practice.
| Book level (USDT) | Fill price (AED) | AED received |
|---|---|---|
| 500,000 | 3.6700 | 1,835,000 |
| 600,000 | 3.6670 | 2,200,200 |
| 500,000 | 3.6630 | 1,831,500 |
| 400,000 | 3.6580 | 1,463,200 |
| Total 2,000,000 | avg 3.66495 | 7,329,900 |
Had the whole ticket filled at the top price of 3.6700, the seller would receive AED 7,340,000; the book pays AED 7,329,900 — AED 10,100 of slippage (about 0.14%), before any fee.
Notice what slippage is not: it is not the fee. A 0.1% taker fee on this trade would be a further AED 7,330, disclosed upfront; the AED 10,100 was invisible until the fills printed. And the average of 3.66495 assumes the book stands still while your order works — in a fast market it does not.
The same sale at an OTC desk looks different. The desk quotes one price for the full 2,000,000 USDT — say 3.6645, a 0.15% spread — held in writing for a defined window. Accept it, and AED 7,329,000 is the fill: every dirham known before a single USDT moves, and more than the exchange route nets after its fee.
Why an OTC quote has no slippage
An OTC quote has no slippage because there is no order book on your side of the trade. You state the amount; the desk checks its own inventory and hedging cost and answers with one number for the whole ticket, firm for a defined window in writing. Accept within the window and that number is the executed price.
The desk absorbs the execution risk an exchange pushes onto you. If the market moves while the desk hedges your ticket, that is the desk's problem, priced into the spread once — which is why the 0.08%–0.40% in our published spread bands is the entire cost, not the starting point of it. Slippage does not disappear from the world; it moves from your side of the trade to the desk's.
How does this work in the UAE?
Selling USDT through a desk in Dubai is a regulated activity: the Virtual Assets Regulatory Authority (VARA) licenses broker-dealers, and a desk's licence number should resolve in the public register — ours is linked from the licence section of the main page. The check matters because slippage is not the only way a bad fill happens; an unlicensed counterparty can simply not pay.
The practical flow matches the mechanics above. You open an account once — passport and proof of address for an individual, the full list in our onboarding requirements — then request a quote, and send USDT only after accepting it in writing. A licensed desk settles to an account in your own name only.
Settlement itself carries no price risk. AED arrives by UAEFTS the same business day you trade; USD goes by SWIFT and takes two to five business days, as of September 2026. Desks in Dubai typically start around 100,000 USDT — below that, an exchange is usually the cheaper route even after slippage.
Why slippage matters when you sell USDT
Slippage matters most when the trade funds something with a deadline — a property payment, a car, a school fee. An expected price is not a plan; a number in writing is. On the 2,000,000 USDT ticket above, the gap between "about 3.67" and a firm quote was AED 10,100, and it scales with size.
The honest comparison is total cost, not headline rate: exchange fee plus slippage plus withdrawal charges plus two or three days of bank timing, against one quoted spread with same-day settlement. For small amounts the exchange usually wins; from six figures up, the desk usually does.
The bottom line on slippage
Slippage is the tax you pay for liquidity you cannot see. On an exchange it is yours; at a desk it is priced, fixed and signed for before you commit.
FAQ
Is slippage the same as a fee?
No. A fee is a published charge you see before you trade; slippage is the unpriced gap between the price you expect and the price you get. Fees are certain, slippage is only known after the fill.
How much slippage is normal for a large USDT sale?
There is no fixed normal: it depends on order-book depth and how fast the market is moving. On a seven-figure USDT ticket, even 0.1% is thousands of dirhams, which is why size moves to desks.
Can a limit order prevent slippage?
A limit order caps the price you accept, but it may fill only in part or not at all. You swap price risk for execution risk, and the unfilled remainder still faces the market.
Does slippage exist at an OTC desk?
No. A desk quotes one all-in price for the full amount and holds it in writing for a defined window. Accept within the window and that price is your fill, whatever the market does meanwhile.
