What is OTC trading?
OTC trading, short for over-the-counter trading, is the direct exchange of financial assets between two parties outside of a public exchange or order book. Instead of matching buyers and sellers through a centralized marketplace, the parties negotiate terms privately, often through a broker or OTC desk that facilitates the transaction.
OTC markets exist across equities, fixed income, derivatives, foreign exchange, and increasingly crypto. In each case the logic is the same: some trades are too large, too specialized, or too sensitive to execute efficiently through a public exchange.
OTC trading in traditional finance
In traditional finance, OTC markets handle a significant share of global trading volume. Most bonds, foreign exchange transactions, and interest rate derivatives trade OTC rather than on centralized exchanges. The FX market, the largest financial market in the world, is almost entirely OTC: banks and institutional counterparties negotiate rates directly rather than trading through a central venue.
Equities can also trade OTC. Companies that do not meet the listing requirements of major exchanges like the NYSE or Nasdaq trade on OTC markets through dealer networks. These are typically smaller companies, though some large foreign companies trade OTC in the US as American Depositary Receipts (ADRs).
OTC trading in crypto
In crypto, OTC trading refers specifically to large block trades executed privately, usually through an OTC desk operated by a major exchange or specialist broker. The minimum trade size varies by provider but typically starts in the range of $50,000 to $100,000 (USD) equivalent.
The main reason large crypto traders use OTC desks rather than public exchanges comes down to market impact. On a public exchange, all orders are visible in the order book. A large buy or sell order moves the price against the trader as it executes, a phenomenon called slippage. A buyer pushing a large order through an order book drives the price up as they buy; a seller drives it down as they sell. The final average execution price ends up worse than the price at the start of the trade.
An OTC trade avoids this. The buyer and seller agree on a fixed price for the entire block before execution. The price does not move during the trade because the trade does not touch the public order book at all.
OTC desks vs. peer-to-peer OTC
There are two main ways OTC crypto trades are structured.
- OTC desks are operated by major exchanges and specialist brokers. Coinbase Prime, Kraken OTC, and similar services connect institutional buyers and sellers through a professional intermediary. The desk quotes prices, matches counterparties, and manages settlement. This is the most common model for institutional OTC activity.
- Peer-to-peer OTC connects buyers and sellers directly through a platform or marketplace without a desk acting as intermediary. P2P OTC platforms are more common in markets where access to centralized exchanges is restricted, and for traders who want to transact in local currencies or payment methods not supported by major exchanges. The counterparty risk in P2P OTC is higher since no professional intermediary is standing between the two sides.
What assets trade OTC in crypto
OTC desks typically support:
- Major cryptocurrencies: Bitcoin, Ethereum, and other large-cap assets
- Stablecoins: USDT and USDC are common OTC instruments, particularly for institutional on and off-ramping
- Altcoins with sufficient liquidity at the OTC level
- In some cases, tokenized assets and structured products not listed on public exchanges
Stablecoins in particular play a significant role in OTC settlement. A buyer converting large amounts of fiat to crypto, or an institution moving between crypto positions and cash, will often use stablecoin OTC as an intermediate step rather than moving through a CEX order book.
How OTC trades settle
Settlement is where payment infrastructure becomes directly relevant to OTC trading. After a price is agreed, the two sides need to exchange assets and funds. Settlement can happen in several ways:
- Fiat wire settlement: The buyer sends fiat currency via wire transfer to the seller or the desk's account, and crypto is released upon confirmation
- Stablecoin settlement: Increasingly common. The buyer sends USDT or USDC and receives crypto in return, or vice versa. Stablecoin settlement is faster than wire and operates around the clock
- Delivery versus payment (DvP): Both legs of the transaction settle simultaneously, reducing counterparty risk. More common in institutional arrangements with custodians involved
Settlement timing and the flow of funds between parties is one of the key operational considerations in OTC trading. Unlike exchange trades that settle through a central counterparty, OTC trades settle bilaterally. If one side delivers and the other does not, there is no central mechanism to automatically reverse the trade.
Compliance in OTC trading
OTC desks are subject to the same compliance requirements as exchanges. Participants are required to complete KYC verification before trading, and desks must maintain AML programs and file suspicious activity reports where required.
P2P OTC platforms vary in their compliance standards. Some operate with full KYC requirements; others, particularly those in less regulated jurisdictions, may have lighter requirements. The compliance gap between regulated OTC desks and informal P2P platforms is one of the reasons regulators have increased scrutiny of P2P OTC activity in several markets.
For institutional participants, OTC counterparty due diligence is part of standard onboarding. Before trading with a new counterparty, both sides typically exchange entity documentation, KYC materials, and in some cases legal agreements governing the trading relationship.
