If your business needs to move a large amount of crypto, converting treasury, settling a big trade, or on/off-ramping size, a public exchange is often the wrong tool. Place a large order on an order book and you move the market against yourself: the price slips as your order fills, and everyone watching can see it happen. Over-the-counter (OTC) trading takes a different route. You work the trade through a dealing desk, which sources liquidity across venues and settles with you directly.
This guide is for the business or desk doing the trading, treasuries, trading firms, payment companies and funds executing size, not retail traders.
What OTC trading actually is
OTC trading means transacting directly with a counterparty (the desk) rather than submitting your own order to a public exchange book. Instead of filling against whatever liquidity happens to be on the book, you tell the desk the size you want to do and it quotes an indicative amount for the full trade. If you want to proceed, the desk works the order and settles with you bilaterally.
The key difference from an exchange is how size is handled. On an exchange, a large order eats through successive price levels: the deeper your order, the worse the average price. An OTC desk prices the whole block and sources liquidity across multiple venues, so the order is worked off the public book by a desk whose job is handling size, rather than being dropped onto one book by you.
Why businesses use a desk
- Deep liquidity. The desk aggregates liquidity from many venues rather than relying on a single book, so it can take on trades that one exchange could not absorb well.
- Indicative pricing for the full size. You get an indicative amount for the whole trade before you commit, so you can assess the trade as one decision. The amount is confirmed at execution, and the market can move.
- Discretion. Large trades aren't broadcast to the market as they fill.
- Operational efficiency. Settlement is streamlined in crypto or fiat, with one counterparty rather than fragmented fills across exchanges.
- Compliance. Trading within a licensed, regulated framework keeps the activity clean for your auditors and banking relationships.
How an OTC trade works, step by step
- Onboard. The desk approves your account after KYC/AML and corporate documents, done once, up front.
- Set up. Whitelist your wallets and bank accounts so settlement can only go to known destinations.
- Fund. Deposit fiat or crypto to your designated accounts.
- Request an amount. In chat with the desk, or through the platform, tell it the asset, direction and size. The desk comes back with an indicative amount for the full size.
- Execute. Confirm you want the desk to proceed. It sources liquidity across venues and works the order off the public order book, and the amount is confirmed at execution.
- Settle. Funds and assets are exchanged on the agreed timeline, often same day, to your whitelisted wallet or bank account.
A worked example
Suppose a payment company has accumulated a large stablecoin balance from settlement activity and needs to convert it to fiat to fund operations. Sweeping that size across exchange order books itself would slip the rate and signal the move to the market. Instead, the company asks an OTC desk for an amount on the full balance. The desk quotes indicatively, works the order across venues, and confirms the amount at execution. The fiat settles to the company's bank account the same day, in one clean settlement, with the size handled by a desk rather than broadcast to a single book.
What to check before you trade
- How pricing is confirmed. Ask what the quoted amount represents, when it is confirmed, and how the desk communicates if the market moves while your order is being worked.
- Settlement terms. Confirm the timeline and that destinations are whitelisted.
- Regulatory standing. Trade through a desk operating under licensed entities with proper KYC/AML.
- Coverage. Check the desk can source the instruments and corridors you need. A good desk isn't limited to what one exchange offers.
Common pitfalls
- Treating OTC like an exchange and shopping a large order around, which leaks information and worsens your price.
- Ignoring settlement risk; whitelisting and a clear settlement process matter as much as the rate.
- Using an unregulated counterparty to save a few basis points, then creating a compliance headache for your bank.
