A service that fills large orders by negotiating one price directly with the client instead of routing the trade through a public order book.
Desks exist because a large order on the book would move the price against the buyer. Every level a market order consumes is a worse price, so buying $20,000,000 of an asset through a public book can cost several percent more than the quoted top of book. A desk quotes one price for the whole size instead.
Minimums sit well above retail size, and settlement terms are agreed case by case. The clients are funds, treasuries, mining operations converting rewards, and family offices, not individuals.
How it works
The client requests a quote for a size and an asset. The desk responds with a single all-in price, valid for a short window, and the client accepts or declines. There is no order book, no partial fill, and no slippage: the price you agreed is the price you get for the entire amount.
The desk then manages its own risk. It may already hold inventory, source the other side from another client, or work the position into public markets over hours. Its profit is the spread between what it quoted and what it can achieve, which is why a desk quote is wider than the top of book but usually narrower than the average price a large market order would achieve.
Two models exist. A principal desk trades against you from its own book and carries the risk. An agency desk finds a counterparty and charges a commission, without taking the other side itself.
Settlement is negotiated. Large trades often settle same-day against a wire, sometimes through an escrow arrangement or a qualified custodian, and the counterparty due diligence is heavier than opening an exchange account.
Example
Illustrative comparison for a $5,000,000 purchase in an asset whose book holds $800,000 within 1% of the mid.
| Route | Expected cost above mid | Certainty of size |
|---|---|---|
| Single market order on the book | Several percent, walking far past 1% | Complete but expensive |
| Worked over hours in small pieces | Lower, but exposed to the market moving | Uncertain |
| OTC quote for the full size | A single negotiated spread | Complete at a known price |
The desk's spread is a real cost. It is being compared against a market impact cost that is often larger and always uncertain.
Why it matters when you buy
At retail size, a desk is not available and not needed, but the same logic scales down. If your order is large relative to the resting depth on a pair, splitting it or using limit orders is your version of the same solution. Check the measured depth and modeled slippage for your intended size on the liquidity pages before deciding, since on a thin pair even a few thousand dollars can behave like a large order.

Questions
Can an individual use an OTC desk?
Minimums are typically well into six figures and vary by desk. Below that, exchange execution with limit orders is the practical equivalent.
Is an OTC price better than an exchange price?
Better than the average price a large order would achieve on the book, usually. Worse than the top of book quote, always, because the spread is the desk's compensation for taking the risk.
Do OTC trades affect the market price?
Not directly at the moment of the trade, since nothing crosses a public book. The desk's subsequent hedging can, which is one reason large trades are often invisible until later.
