What Is OTC Crypto Trading? How Institutions Execute Block Trades

How an OTC Trade Works

Over-the-counter (OTC) trading is bilateral. Instead of placing an order on an exchange where it matches against anonymous resting orders, the client trades directly with a liquidity provider that quotes a price for the whole size. The provider takes the other side of the trade onto its own book and manages the resulting position.

The sequence is short. The client specifies the asset, the side, and the quantity, and often the settlement currency. The desk returns a firm price that is executable for a defined window. The client accepts or lets the quote expire. On acceptance, the trade is binding and settlement proceeds on terms agreed in advance. Every step is timestamped, which is what makes the workflow auditable for a compliance team.

The mechanism is the same one institutional desks use in fixed income and foreign exchange. Digital assets add two differences: markets run 24/7, and settlement of the asset leg happens on a blockchain or between custody accounts rather than through a central securities depository.

Why Institutions Trade OTC

A central limit order book shows liquidity only for the quantities displayed at each price level. A block that exceeds displayed depth fills at successively worse prices, and each fill signals intent to other participants who can trade ahead of the remaining quantity. The cost of that process is slippage and market impact, and it grows with order size relative to depth.

OTC execution moves the problem to the liquidity provider. The desk prices the block against its inventory and its ability to hedge across venues over time. The client receives one price and no market impact of its own making. The desk's compensation is the spread on the quote, which reflects the risk of working the position.

Three situations make OTC the default:

• Size relative to depth. Any order that would consume a material share of the visible book.
• Thin assets. Pairs where displayed depth is shallow even for moderate notional.
• Sensitive flow. Trades that must not signal a treasury's, an issuer's, or a fund's activity before completion.

RFQ: The Core Workflow

The request for quote (RFQ) is how most institutional OTC flow executes. The client can request a one-way price, revealing the side, or a two-way price, which hides direction until acceptance. Two-way requests cost slightly more in spread because the desk must be prepared to trade either way, but they reduce information leakage further.

Institutional desks run RFQ over private channels: a trading portal, an API over FIX or REST, or a secure chat with a trader. Automated RFQ lets a client's order management system request, compare, and accept quotes without manual steps, which matters for treasuries that convert on a schedule and for issuers that must execute creations and redemptions at defined times.

Pricing, Spreads, and Settlement

A quote has three components: a reference price drawn from the venues where the desk hedges, a spread that compensates the desk for risk and cost of carry, and the terms that govern settlement. The spread is the visible cost. Whether it is a good price depends on what the alternative would have cost: the expected slippage of executing the same size on an order book, plus the cost of the information leaked along the way.

Settlement is where quotes stop being comparable on price alone. A quote that settles same-day in stablecoin and a quote that settles in two days by wire are different products. So are quotes that require the client to pre-fund the desk and quotes that settle delivery-versus-payment. An institution comparing desks lines up settlement currency, timing, netting, and fees before comparing spreads.

Risks and How Desks Control Them

The principal risks in OTC trading are counterparty risk and settlement risk. Counterparty risk is the possibility that the desk fails to perform. Settlement risk is the narrower possibility that one leg of a trade moves before the other. Desks control both with documented terms, defined settlement cutoffs, sequencing that moves the asset and cash legs close together, and netting of offsetting obligations.

Regulatory status is part of the same picture. In the United States, FinCEN's 2019 guidance treats businesses that exchange convertible virtual currency for funds as money transmitters, which are money services businesses that must register with FinCEN. Canada's FINTRAC regime is comparable. Bermuda licenses digital asset businesses under its Digital Asset Business Act. Registration and licensing do not remove counterparty risk, but they establish the compliance obligations a desk operates under and give an institution something to verify.

What to Ask an OTC Desk

Before trading size with a new desk, an institution can resolve most of the unknowns with a short list of questions:

1. Which registrations and licenses does the desk hold, in which entities, and where can they be verified?
2. Are quotes firm for the full size, and for how long?
3. Which settlement currencies, rails, and cutoffs are supported, and is pre-funding required?
4. How is the digital asset leg custodied and moved, and what controls govern withdrawals?
5. What is the desk's hedging footprint, and how does it avoid signaling client flow?
6. Which connectivity is available for automated RFQ, and how are trades reported?

The answers determine whether a tight quote is also a good one.
