What is OTC crypto trading, and why do institutions use it?

OTC crypto trading is the purchase or sale of a crypto asset agreed directly between two parties, usually a client and a dealing desk, at one negotiated price for the whole amount, instead of through the public order book of an exchange. Institutions use it because a large order placed on an order book moves the price against itself and shows the market what the institution is doing, while an OTC trade gives one known price for the full size, agreed in private, with settlement terms that fit how a fund or a treasury actually moves money.

"OTC" stands for over the counter, a term inherited from securities, currency and derivatives markets, where much of the world's large trading has always been done between dealers and their clients away from a central exchange. Crypto borrowed the model once holders appeared whose positions were too large for the visible market: funds, corporate treasuries, family offices, miners, token issuers and long-standing private holders.

What does "over the counter" mean in crypto?

In crypto, "over the counter" means a trade negotiated and agreed bilaterally, between two identified parties, with a price and settlement terms that apply to that trade only. Nothing is posted to a public order book before the trade, and the price is not printed on a public tape afterwards.

The contrast is with an exchange. The International Monetary Fund's Finance & Development magazine, in a 2008 explainer on these markets, describes an exchange as a place that centralizes the communication of bid and offer prices to all participants, and an OTC market as a less formal, though often well-organized, network of trading relationships centered on one or more dealers. The same article notes that OTC markets are less transparent and operate with fewer rules than exchanges. Both halves carry over to crypto: the dealer network is where size trades, and the client has to bring its own price reference.

Three points are often misunderstood.

• Off the book is not off the record. A trade with a professional desk is documented, confirmed in writing, booked by both sides and, in most jurisdictions, done with a regulated firm that has identified its client. The asset leg still moves on a public blockchain or across the books of a custodian.
• OTC describes how the price is formed, not what is traded. Most OTC crypto activity is spot: an asset against a currency or a stablecoin, delivered within hours or a day. Forwards, options and financing are also negotiated over the counter, with heavier documentation.
• OTC is not one venue. It is a set of relationships: principal desks, brokers, block services run by exchanges, request-for-quote platforms and direct trades between two holders. A block trade is a single large transaction negotiated this way. A dark pool is different: it is a venue that matches orders without displaying them, so it remains a matching system.

Private does not mean anonymous. The parties know exactly who they are dealing with; what stays private is the order, before it is filled.

Who takes part in an OTC crypto trade?

An OTC crypto trade involves a client with size to move, a desk or broker that prices or arranges the trade, the liquidity providers behind that desk, and the custodians and banks that move the two legs. Each one has a different job and a different exposure.

The distinction that matters most is between a principal and an agent. A principal is your counterparty: it buys your asset onto its own book and its gain is the gap between your price and the price at which it offsets. An agent arranges a trade between you and a third party and charges a stated fee. European rules draw the same line: under the EU's Markets in Crypto-Assets Regulation, exchanging crypto-assets "by using proprietary capital" is one service and executing orders on behalf of clients is another, and the European Securities and Markets Authority treats the first as the firm acting as the client's counterparty and the second as the firm acting as the client's agent.

The capacity should never be a guess. The International Organization of Securities Commissions, in its 18 policy recommendations for crypto and digital asset markets published in November 2023, asks regulators to require a service provider to disclose each role and capacity in which it acts, including whether it handles a client's order as principal or as agent. Ask the question before the first quote, and get the answer in the onboarding documents.

How does OTC trading differ from trading on an exchange order book?

An exchange order book matches many anonymous orders at publicly displayed prices, level by level; an OTC trade is one transaction with one known counterparty at one agreed price. The differences follow from that.

Neither column is better in general. The order book is transparent, continuous and cheap for amounts the displayed depth can absorb. The OTC route gives up transparency to obtain certainty on size. Many institutions use both: the book for routine amounts and rebalancing, a desk for the positions that would disturb the book.

Why do large holders trade off the order book?

Large holders trade off the order book because the visible depth of a market is small compared with the positions they hold, so a large order pays a worse price with every level it consumes and tells other participants which way the holder is trading. An OTC trade transfers that execution problem to a firm whose business is to manage it.

Six reasons come up in practice.

Price impact. An order book shows a limited quantity at each price. A sale larger than the best bid fills the next bid, then the next. The difference between the price expected and the average price obtained is called slippage, and it grows faster than the order does.

Information. A large order resting on the book, or a series of fills marching down it, is a public signal. Other participants adjust their own prices before the holder has finished. A fund selling a position over several hours can find the market lower because of its own first fills. An OTC request reaches only the desks asked to quote.

Certainty. A treasury that must convert a known amount for a known purpose, such as a payroll, an acquisition, a redemption or a tax payment, needs to know the proceeds before it commits. A firm OTC quote states the price for the entire size. The alternative on a book is to split the order over time, which reduces impact but leaves the holder exposed to wherever the market goes meanwhile.

Access to currency. Many institutions need to end in a bank account, in their own currency, under their own name. A desk settles the currency leg by bank transfer and the asset leg to or from the client's custodian, so the client does not have to pre-fund an exchange account with the whole position.

Assets and pairs the book does not serve. A thinly traded token, a locked allocation or an unusual currency pair may have almost no displayed depth. A desk or broker can find a specific buyer for it, which no order book can.

Governance. One counterparty, one written confirmation and one settlement instruction are easier to approve and audit than several hundred partial fills.

The desk is paid for this through the spread, which is the gap between its price and a reference price. The spread is a real cost, and the worked example below shows when it is worth paying and when it is not.

What does a large order cost on the book and over the counter?

A large order costs more on an order book than the best displayed price suggests, because the average price worsens with every level consumed; over the counter, the cost is the spread on a single price. Below a certain size the order book is the cheaper route, and above it the desk is.

Take a worked example with invented figures. A corporate treasury holds 250 units of a crypto asset. The mid price, halfway between the best bid and the best offer, is $40,000, so the position is worth $10,000,000 at mid. The exchange charges a trading fee of 10 basis points on the amount traded. The bid side of the book looks like this:

Selling all 250 units at once into this book brings $9,952,200 before fees, an average of $39,808.80 a unit. Slippage against the mid price is $47,800, or 47.8 basis points. The exchange fee on $9,952,200 adds $9,952.20. The treasury nets $9,942,247.80, a total cost of $57,752.20.

A desk, asked for a firm price on the full 250 units, quotes $39,900, which is 25 basis points below mid, with no separate commission. The treasury nets $9,975,000, a cost of $25,000. The desk route leaves $32,752.20 more, and the treasury knew the figure before it agreed.

Now reverse the size. A holder selling only 20 units, $800,000 at mid, fills entirely at the first bid: $400 of slippage and $799.60 of fee, $1,199.60 in total, or about 15 basis points. The same 25 basis point quote would cost $2,000. For that order the book is cheaper by $800.40.

Two cautions keep the example honest. First, a real desk does not quote the same spread for every size: its price also widens as the position gets harder to offset, only more slowly than a thin book does, and for a small amount it may decline to quote at all. Second, the treasury had a third route, which is to work the order through the book in slices over several hours. That can beat both figures on a quiet day and lose to both when the market moves, because the unsold part stays exposed. What the example shows is the shape: order book cost climbs with size, and somewhere along the way the two routes cross.

What does the life of an OTC trade look like?

An OTC trade runs in six stages: onboarding, the request, the quote, the agreement, settlement and the record. The first is done once per counterparty; the other five repeat on every trade and can take minutes for a liquid asset between established parties.

Settlement deserves one remark at this level. Because two different assets move on two different systems, one party is usually exposed for a period after delivering its leg and before receiving the other. Established desks manage this through agreed delivery sequences, pre-funding, credit limits or a third party holding one leg, and the method should be settled before the trade, never during it.

Is OTC crypto trading regulated?

OTC crypto trading is legal and regulated in most major financial centres, but the regime differs by country and by the asset traded. The firm on the other side is normally subject to anti-money-laundering rules at minimum, and in a growing number of jurisdictions to a full licensing regime.

The common base is set by the Financial Action Task Force, the global standard-setter for anti-money-laundering rules. Its updated guidance of 2021 defines a virtual asset service provider as a business that carries out certain activities for or on behalf of another person, and the list opens with exchange between virtual assets and fiat currencies and exchange between one or more forms of virtual assets. A desk that deals for clients falls within that description whether or not it runs an order book. The same guidance sets a threshold of USD/EUR 1,000 for occasional transactions, above which providers must conduct customer due diligence. No institutional trade is anywhere near that small, which is why onboarding comes before the first quote.

National rules build on that base. The European Union licenses crypto-asset service providers under the Markets in Crypto-Assets Regulation, with separate services for dealing on proprietary capital, executing client orders and receiving and transmitting them. Other jurisdictions use registration with a financial intelligence unit, a securities or payments licence, or a dedicated digital asset regime.

For the client, the practical consequence is that the regulatory status of a desk is a fact to verify, not a claim to accept. Regulators publish registers of the firms they authorise; the entity named on the desk's agreement should appear there, under the same legal name, for the service it is offering you. All of this is general information. Which rules apply to a given trade depends on where the parties are established and on the asset, and is a question for your own counsel.

What are the risks of trading OTC?

The main risks of an OTC crypto trade are counterparty risk, settlement risk, an uncompetitive price, leakage of the client's intentions, impersonation and operational error. Most of them are the other side of the advantages: a private, bilateral trade has no exchange in the middle to display prices or guarantee delivery.

Price risk is the one most specific to this market. On an exchange, a participant sees the book. Over the counter, the client sees only what it is quoted, so it has to bring its own reference: the mid price on the main venues at the time of the request, a published index, or a second and third quote.

Counterparty risk is the one with the largest consequences. A desk that takes your asset onto its own book owes you the other leg until it arrives, and a desk that holds client balances between trades is a firm whose solvency matters to you. Institutions limit how much may be outstanding with any one counterparty at a time, and they keep balances with a desk no longer than a trade requires.

What does an institution need in place before its first OTC trade?

Before its first OTC trade, an institution needs a completed onboarding with at least one desk, a list of the people authorised to trade, verified settlement details on both sides, a price reference and an internal approval rule. None of this can be assembled on the day a position has to be sold.

• Entity file. Formation documents, registers of directors and owners, proof of address, and the documents showing where the assets or funds come from. A holder whose position goes back many years should expect detailed questions on its origin.
• Authorised traders. A written list, held by the desk, of who may request and accept prices, with a limit per person. A price accepted by an authorised trader binds the institution.
• Custody and wallets. The addresses or custodian accounts that will deliver and receive, communicated and confirmed in advance, and a clear internal procedure for releasing assets from storage in time for the agreed settlement.
• Banking. An account in the institution's name at a bank that has been told to expect proceeds from digital asset sales.
• Benchmark. A decision, taken beforehand, on which price source the institution will measure each quote against.
• Approval rule. Who signs off a trade above a given size, and what is the maximum exposure to one counterparty.
• Relationships. Onboarding with two or three desks takes weeks of elapsed time. Doing it before it is needed is what allows a comparison of quotes when it matters.

Who is OTC crypto trading not for?

OTC crypto trading is not for orders the public order book can absorb at its best prices, for parties that cannot or will not complete onboarding, or for anyone who needs a displayed, continuous market more than a single negotiated price.

Orders the book handles well. The 20-unit sale in the worked example was cheaper on the exchange. Each desk sets its own minimum trade size and publishes it or states it on request; below that size, and for liquid pairs generally, an exchange account is the right tool.

Parties that want anonymity. Regulated desks identify their clients and ask where the assets come from. A holder unwilling to document that will not be onboarded, and the unregulated alternatives that ask no questions carry the highest counterparty and impersonation exposure in the market.

Parties without a price reference. A client that cannot check a quote against the market is relying entirely on the desk's fairness.

Strategies that need the book. A trading strategy that depends on resting orders, immediate small fills or rule-based execution through the day needs an exchange and its interfaces. A desk suits positions; it is not built for a stream of small tickets.

Trades that need a guaranteed middle. If neither party will accept exposure to the other during settlement and no arrangement has been agreed to cover it, the trade is not ready, whatever the price.

For everyone else holding size, the question is rarely whether to use OTC or an exchange. It is which positions go where, and with which counterparties, and the answer is set by the numbers: the depth of the book against the size to move, the quote against the reference, and the exposure the institution is prepared to carry until both legs have arrived.
