When I review an OTC trade, I don’t treat the label itself as a risk score. I write down four answers:
- Who is my counterparty?
- How was the price formed?
- How will the trade clear and settle?
- What happens if I need to exit early?
Those answers tell me more than the word “OTC.”
Over-the-counter trading means that a trade is negotiated or executed outside a centralized exchange order book. It may still involve a broker, a dealer, an electronic platform, a clearing house, a custodian and regulatory reporting.
OTC does not mean “no middleman.” It does not mean “unregulated.” And it does not mean that two people privately agree on a price by phone. Many OTC markets are electronic and heavily intermediated.
What is OTC trading?
An OTC trade is arranged outside the public order book of a formal exchange.
The buyer and seller may deal directly. More often, a dealer stands between them. The dealer quotes a price, executes as the counterparty and may later hedge the resulting position elsewhere.
A broker can also act as an agent. In that case, the broker finds another party or requests prices from several dealers instead of taking the other side of the trade.
This creates three distinct roles:
- Client: the investor, company, fund or other party that wants to trade.
- Dealer: quotes a buying and selling price and may trade from its own inventory.
- Broker or platform: connects participants, requests quotes or routes the trade.
The exact structure depends on the market. A corporate FX forward, a government bond, an interest-rate swap, an OTC stock and a crypto block trade all use different mechanics.
OTC vs exchange trading
An exchange brings orders into a centralized matching system. An OTC market relies on dealer quotes, bilateral negotiation or another off-exchange protocol.
| Question | Exchange trading | OTC trading |
|---|---|---|
| Where is the trade executed? | On an exchange under its rulebook | Outside a centralized exchange order book |
| How is the price found? | Displayed bids and asks compete in the book | A dealer quote, RFQ, price stream or negotiated price |
| Are terms standardized? | Usually yes | They may be standard or customized |
| Is pre-trade liquidity visible? | Some or all of the book may be visible | Often limited to the quotes requested or received |
| Who is the counterparty? | The trade commonly passes through exchange clearing | A dealer, another client or a central counterparty |
| Can the trade be centrally cleared? | Commonly | Yes for some standardized OTC products; other trades remain bilateral |
| Are completed trades reported? | Under the rules of the exchange and jurisdiction | Reporting depends on the instrument and local rules |
| When can it trade? | During the venue’s sessions | Depends on the market, dealer and settlement arrangements |
An order book shows prices available on a specific venue. An OTC quote shows what a particular counterparty is prepared to trade, in a stated size, at that moment.
The same asset can use both routes. An exchange-listed share can trade off-exchange. A standardized derivative can be agreed OTC and then sent to a central counterparty for clearing. “OTC” describes the execution structure, not the full life of the trade.
Off-exchange execution is also broader than dark pool trading. A dark pool hides resting orders before execution. An OTC trade may instead use a dealer quote or bilateral negotiation.
How an OTC trade works
One common method is a request for quote, or RFQ.
The client specifies:
- the instrument;
- whether it wants to buy or sell;
- the amount;
- the maturity or settlement date;
- any conditions attached to the trade.
The request goes to one dealer or several dealers. Each dealer decides whether to quote and at what price. The client compares the executable responses, accepts one and receives a confirmation.
The trade then moves into clearing, collateral management, settlement and reporting as required. These post-trade steps may involve different firms and systems from the ones that arranged the quote.
OTC RFQ: quote to settlement
Buy USD in 90 days
USD 5,821,500 on the value date
An FX forward example
Assume a company will receive EUR 5 million in 90 days. Its costs are in US dollars, so it wants to fix the dollar value now rather than wait for the future EUR/USD spot rate.
It asks three banks for an executable 90-day forward quote to sell EUR 5 million and buy dollars.
| Dealer | EUR/USD forward quote | Dollars fixed for EUR 5 million |
|---|---|---|
| A | 1.1638 | $5,819,000 |
| B | 1.1643 | $5,821,500 |
| C | 1.1636 | $5,818,000 |
Dealer B offers the highest number of dollars for the euros. Its quote produces $2,500 more than Dealer A and $3,500 more than Dealer C.
B’s price looks best, but price is not the whole decision. The company must still check that the quote is firm for the full amount, review credit and collateral terms, confirm settlement instructions and account for any fees outside the rate.
The forward rate is not a dealer’s prediction of where EUR/USD will trade in 90 days. It reflects the spot rate, the interest-rate difference between the two currencies, maturity, market liquidity and the dealer’s pricing.
A currency future can hedge a similar risk, but it comes in standardized contract sizes and dates. The OTC forward can match the company’s exact EUR 5 million exposure and payment date.
How dealers make money on OTC trades
A dealer normally quotes a buying price and a selling price. The difference is the bid-ask spread. It may also charge a commission, financing cost, credit charge or settlement fee.
I never assume that “commission-free” means free.
Suppose an observable reference price is 100.00 and a dealer offers to sell at 100.40. The difference is 0.40%, or $1,000 on a $250,000 trade, before any other costs.
The reference price may not be executable for the required size. But the calculation makes the embedded spread visible. Compare quotes for the same instrument, size and settlement terms at roughly the same time.
Principal and agency execution
The word “broker” can hide an important difference.
| Model | Provider’s role | How it may earn |
|---|---|---|
| Principal | Trades against the client using its own balance sheet | Spread, fees and management of the resulting position |
| Agency | Searches for a counterparty or routes the order | Commission or another disclosed fee |
Principal execution can provide immediate liquidity, but the dealer sets the quote and takes the other side. Agency execution avoids that exact structure, but the result still depends on which counterparties the broker can reach and how it routes the order.
Before trading, I want one sentence from the provider: Are you acting as principal, agent or both?
In securities markets, one firm may perform both roles. The broker-dealer guide explains how the firm’s capacity changes from one transaction to another.
Which markets trade OTC?
OTC is a market structure, not one asset class.
| Market | Typical OTC instruments | What matters most |
|---|---|---|
| Foreign exchange | Spot FX, forwards, FX swaps, currency swaps and options | Dealer pricing, credit, settlement and rollover terms |
| Fixed income | Government, corporate and municipal bonds | Dealer inventory, RFQ coverage, issue liquidity and trade size |
| Derivatives | Forwards, swaps and customized options | Documentation, collateral, valuation, clearing and counterparty risk |
| Equities | Unlisted securities and off-exchange trades in listed shares | Disclosure, liquidity, quotation quality and broker access |
| Crypto | Large spot transactions and negotiated block trades | Counterparty, custody, source of liquidity and settlement |
| Retail OTC products | CFDs and some rolling spot products | Provider role, pricing method, margin, conflicts and local regulation |
OTC foreign exchange
The global FX market is predominantly OTC. It uses direct dealer relationships, single-bank systems, multi-dealer platforms, electronic matching and voice execution.
The BIS measured average global FX turnover at $9.6 trillion per day in April 2025. FX swaps accounted for about $4 trillion and spot transactions for about $3 trillion. This is a professional market figure, not retail trading volume.
FX trades across the global business week. Liquidity still varies by currency pair and hour, and the market is not universally open 24/7.
Bonds
Many bonds trade through dealers rather than one consolidated public order book. A client may request several prices. A dealer holding the bond may quote more aggressively than one that first needs to find inventory. Electronic RFQ makes comparison faster, but the trade remains OTC.
OTC derivatives
OTC derivatives include forwards, swaps and customized options. Futures are different: they are standardized exchange-traded contracts.
Customization is useful when a company or institution needs an exact amount, maturity or payoff. The same flexibility makes valuation and an early exit more complicated.
Some standardized OTC derivatives face central-clearing, margin and reporting requirements. Other contracts remain bilateral and use collateral and netting. Treatment depends on the product and jurisdiction.
At the end of June 2025, the notional value of outstanding OTC derivatives was $846 trillion, according to the BIS. The gross market value was much smaller at $21.8 trillion. Notional value is the reference amount used to calculate contractual payments. It is not the amount invested, the market value of the contracts or the sum at risk.
OTC stocks
“OTC stock” usually refers to a security quoted outside a national securities exchange. This can include smaller companies, foreign issuers, community banks and delisted companies. It is not another name for a promising startup. Disclosure and liquidity vary sharply.
The US market provides a useful example, but it is not a global template. Its current OTC Markets tiers include OTCQX, OTCQB, OTCID and Pink Limited. Retail orders go through registered broker-dealers. The tier indicates information and eligibility standards, not liquidity or suitability.
An exchange-listed share can also be executed off-exchange. The company remains exchange-listed.
Crypto OTC
A crypto OTC desk can arrange a large trade without placing the full order in a public exchange book. This may reduce visible market impact.
The trade is private, not anonymous. A professional desk normally identifies its client. The client still needs to know where the assets come from, who holds them during settlement and whether the spread is embedded in the quote.
CFDs and other retail OTC products
A CFD is a contract between the customer and the provider based on the price movement of an underlying market. It gives the customer price exposure rather than ownership of the underlying asset.
The provider may act as principal and hedge some exposure elsewhere. Check how prices are derived, how orders execute, which margin rules apply and which legal entity holds the account. Protections differ by jurisdiction.
Benefits of OTC trading
| Benefit | What it changes |
|---|---|
| Exact terms | Amount, maturity, settlement and payoff can match a specific exposure |
| Large-trade capacity | A dealer may absorb a block instead of exposing it in a public book |
| Wider instrument choice | Clients can reach currencies, bonds, maturities and contracts unavailable on one exchange |
| Competing quotes | A multi-dealer RFQ can improve price comparison where no single public book exists |
None of these benefits guarantees a good price. A tailored contract may be harder to value and exit. A large dealer quote may include the cost of taking that risk.
Risks and costs of OTC trading
| Risk | What I check |
|---|---|
| Counterparty | Credit quality, collateral, netting, clearing and default terms |
| Price transparency | Several firm quotes or a usable benchmark for the same size |
| Liquidity and exit | Who will price an early close and how wide that price could be |
| Settlement and custody | Where cash and assets go and whether delivery-versus-payment applies |
| Conflict of interest | Whether the provider is principal, agent or both |
| Documentation | Legal entity, amount, date, currency, collateral and valuation method |
Some OTC markets, including major FX pairs, are highly liquid. Others trade rarely. Liquidity must be judged for the specific instrument and size.
Central clearing, margin, collateral and netting can reduce counterparty exposure while leaving residual risk. In a bilateral trade, the counterparty and legal agreement matter directly.
I also check the confirmation while the trade is fresh. An otherwise sensible trade can fail because the wrong account, date or currency reaches settlement.
Is OTC trading regulated?
Yes, but there is no single global OTC rulebook.
Rules depend on the instrument, participant and jurisdiction. They may cover dealer authorization, client disclosures, trade reporting, clearing, margin, capital, market conduct, custody and settlement.
This is why “OTC is unregulated” is wrong. “OTC regulation varies” is accurate.
The legal entity matters more than the website’s footer or brand. Before opening an account or signing a trading agreement, verify which company will be the counterparty and which regulator, if any, oversees that activity.
When OTC may make sense
OTC can be useful when:
- the amount or maturity must match a specific exposure;
- the required instrument is not available on an exchange;
- the trade is large relative to displayed liquidity;
- a dealer can provide balance sheet, inventory or credit;
- a company needs a tailored hedge;
- a client can compare firm quotes and manage settlement.
An exchange may be the cleaner route when:
- a suitable standardized product already exists;
- public price discovery matters;
- the position must be easy to enter and exit;
- central clearing is important;
- the trade is small enough to execute efficiently in the book;
- the client lacks the systems or documentation to manage a bilateral contract.
The choice is not “safe exchange” against “risky OTC.” It is a comparison of price, liquidity, customization, counterparty, clearing and operational work for one specific trade.
What matters in an OTC trade
OTC trading is not a hidden alternative to the “real” market. It is a core part of global FX, fixed-income and derivatives trading.
Its main strength is flexibility. Its main weakness is that the client must understand more of the trade: who prices it, who carries the obligation, how it settles and what it will cost to leave.
I would not accept an OTC quote because it looks cheaper than an exchange price. I would accept it only after comparing the full route from price to settlement.
