**Over-the-counter (OTC) trading** is the buying and selling of financial instruments outside an exchange’s centralized order book, usually through bilateral negotiations, broker-dealers, or networks of dealers. It is a way of organizing trades, not an asset class: stocks, bonds, currencies, derivatives, and [cryptocurrencies](https://iq.wiki/wiki/cryptocurrency) can all trade OTC. The term can describe an unlisted security or a trade executed off-exchange, including a trade in a security that is listed on an exchange.[\[1\]](#cite-id-cnsd0uk4ao)​[\[2\]](#cite-id-trr9hpfl0r)​

## Structure and Execution

OTC markets operate through networks rather than a single exchange matching buyers and sellers. A broker may act as an agent, finding a counterparty or seeking quotes from dealers; a dealer may trade directly with a client, using its own inventory or taking on the other side of a transaction. Market makers provide buy and sell quotes, while electronic platforms and communication networks can connect participants. These roles may overlap, and an OTC transaction can involve intermediaries, clearing, custody, and regulatory reporting.[\[3\]](#cite-id-1zmp0d5a02)​[\[4\]](#cite-id-lz9kgter8b)​

Prices can be set through dealer quotations, bilateral negotiation, electronic price streams, or a request-for-quote (RFQ) process. In an RFQ, a buyer or seller specifies an instrument and transaction size, and one or more dealers return prices; the client can compare the quotes before accepting one. The agreed transaction is then confirmed and settled according to its terms. Unlike an exchange order book, an OTC quote is generally specific to a particular counterparty, size, and time rather than a publicly visible price available to all participants.[\[5\]](#cite-id-ucf39vtuh0)​[\[4\]](#cite-id-lz9kgter8b)​

OTC does not necessarily mean that a trade is private, unregulated, or uncleared. Some transactions are privately negotiated and settled bilaterally, while others use electronic platforms, clearing houses, [collateral](https://iq.wiki/wiki/collateral) arrangements, or reporting systems. Similarly, an electronic communication network may facilitate off-exchange trades without being an exchange itself.[\[4\]](#cite-id-lz9kgter8b)​[\[2\]](#cite-id-trr9hpfl0r)​

## Instruments and Markets

### Foreign Exchange

Foreign exchange (FX) is a major OTC market in which banks and other participants trade currencies through networks of dealers rather than a single global exchange. Banks and market makers provide quotes, which brokers and platforms can pass on to other participants. The market operates across global time zones, though liquidity varies by currency pair and time of day.[\[6\]](#cite-id-7udkge7c7d)​[\[5\]](#cite-id-ucf39vtuh0)​[\[4\]](#cite-id-lz9kgter8b)​

### Bonds and Derivatives

Many government, corporate, and municipal bonds trade through dealers. Differences in maturity, coupon, issuer, and credit quality can make bonds less uniform than exchange-traded products, so buyers may request quotes for particular issues or transaction sizes.[\[7\]](#cite-id-8p13xtery2)​[\[5\]](#cite-id-ucf39vtuh0)​

OTC derivatives include forwards, swaps, options, and credit default swaps. Their terms can be tailored to an exposure, such as a specific amount, maturity, reference asset, or settlement method. This flexibility can help businesses and financial institutions hedge risks, but customized contracts can be harder to value or exit than standardized exchange-traded products. Some OTC derivatives are centrally cleared; others remain bilateral and expose each party to the other’s ability to meet its obligations.[\[7\]](#cite-id-8p13xtery2)​[\[8\]](#cite-id-4bpf0kzqk3)​[\[4\]](#cite-id-lz9kgter8b)​

### Equities and OTC Quotations

In U.S. equities, “OTC stock” commonly means a security that is not listed on a national exchange and is quoted through an OTC venue. Such securities can include shares of small or foreign companies, as well as delisted or financially distressed issuers. Some securities listed on an exchange can also be traded off-exchange, so OTC execution and OTC listing are not always the same thing.[\[2\]](#cite-id-trr9hpfl0r)​[\[4\]](#cite-id-lz9kgter8b)​

OTC Markets Group operates quotation and trading platforms for OTC securities; it is not itself a traditional stock exchange. Its named markets have included OTCQX, OTCQB, OTCID Basic Market, and Pink categories, including Pink Open Market and Pink [Limited](https://iq.wiki/wiki/limited). These classifications distinguish issuer eligibility and disclosure expectations, but a tier alone does not establish a security’s liquidity or investment quality.[\[7\]](#cite-id-8p13xtery2)​[\[1\]](#cite-id-cnsd0uk4ao)​[\[4\]](#cite-id-lz9kgter8b)​[\[2\]](#cite-id-trr9hpfl0r)​

OTCQX is the upper tier, with higher financial, governance, and disclosure standards than lower OTC categories. OTCQB is aimed primarily at developing companies and includes reporting and verification requirements. OTCID Basic Market and Pink categories cover securities subject to less extensive reporting or issuer participation; Pink securities vary in the amount of current information available. A lack of disclosure can make it more difficult to assess an issuer, but the Pink category does not mean that every security in it has the same characteristics.[\[7\]](#cite-id-8p13xtery2)​[\[1\]](#cite-id-cnsd0uk4ao)​

OTC Markets Group was previously known as Pink Sheets, a name that contributed to the use of “Pink Sheets” for OTC securities. The Financial Industry Regulatory Authority’s OTC Bulletin Board, another historical quotation service, no longer operates.[\[2\]](#cite-id-trr9hpfl0r)​

### Cryptocurrency

​[Cryptocurrencies](https://iq.wiki/wiki/cryptocurrency) can trade on centralized exchanges, directly between counterparties OTC, or through decentralized exchanges, depending on the venue. OTC desks are used for large transactions, often by institutions and high-net-worth clients, who may seek to negotiate a price without placing the full order in a public exchange book. Private execution can reduce visible market impact, but it does not remove risks related to pricing, counterparties, or settlement.[\[1\]](#cite-id-cnsd0uk4ao)​[\[9\]](#cite-id-mxwkcjg3od)​[\[10\]](#cite-id-pmlrt1pvjl)​[\[11\]](#cite-id-dax1wns1up)​

### Electricity

In electricity markets, OTC trading commonly involves bilateral sales outside a power exchange. Parties negotiate volumes and prices for short-term spot products or longer-term contracts; the contract terms and prices are generally known to the parties, while exchange prices can serve as benchmarks. Longer-term contracts can help buyers and sellers secure prices for specified electricity volumes and periods, including to manage exposure to changing spot prices.[\[12\]](#cite-id-ciwtg638s6)​

Some electricity contracts are based on standardized frameworks even when traded OTC. Exchanges such as the European Energy Exchange offer standardized OTC contracts that can be cleared through European Commodity Clearing; the EFET framework contract is another template that parties can adapt. In the European Union, the Regulation on Wholesale Energy Market Integrity and Transparency (REMIT) establishes reporting obligations intended to improve transparency and address market manipulation and insider trading. In Germany, the Federal Network Agency monitors compliance through its market transparency unit.[\[12\]](#cite-id-ciwtg638s6)​

## Uses and Trade-Offs

OTC markets allow trading in instruments or transaction sizes that may not fit an exchange’s standardized products. They can provide access to unlisted securities, less commonly traded bonds, and customized derivatives. Parties may also negotiate terms such as size, maturity, or settlement method. For large orders, private execution can limit the price impact that might result from placing the entire order in a public order book.[\[6\]](#cite-id-7udkge7c7d)​[\[11\]](#cite-id-dax1wns1up)​[\[3\]](#cite-id-1zmp0d5a02)​

Those features involve trade-offs. OTC prices and transaction details are often less visible than exchange prices, dealer quotes can differ, and bid–ask spreads may be wider. Liquidity depends on the instrument, size, and market conditions; it may be difficult to complete a trade or exit a position at a desired price. Bilateral transactions can also carry counterparty and settlement risk, particularly when no central clearing house guarantees performance. Limited issuer disclosure can add uncertainty in OTC equities, and lower-priced or thinly traded shares may be volatile.[\[7\]](#cite-id-8p13xtery2)​[\[5\]](#cite-id-ucf39vtuh0)​[\[1\]](#cite-id-cnsd0uk4ao)​

OTC derivatives’ scale and complexity have drawn particular attention to risk management. [Collateral](https://iq.wiki/wiki/collateral), margining, netting, legal agreements, and central clearing can reduce some counterparty exposures, but do not eliminate all risk. OTC trading is not inherently a “black market”; its legal requirements and protections depend on the instrument, participant, and jurisdiction.[\[8\]](#cite-id-4bpf0kzqk3)​[\[4\]](#cite-id-lz9kgter8b)​

## Regulation

There is no single global rulebook for OTC trading. Regulation can address dealer authorization, disclosure, trade reporting, clearing, margin, capital, and market conduct, with different requirements for different products and jurisdictions.[\[4\]](#cite-id-lz9kgter8b)​[\[5\]](#cite-id-ucf39vtuh0)​

In the United States, the Securities and Exchange Commission (SEC) applies rules concerning fraud, manipulation, and issuer information. Broker-dealers must have current publicly available information about an issuer before publishing quotations for its securities under the applicable SEC rule. FINRA oversees OTC broker-dealers, monitors trading, and requires reporting of OTC equity transactions. The Commodity Futures Trading Commission (CFTC) regulates OTC derivatives and currency transactions.[\[7\]](#cite-id-8p13xtery2)​[\[13\]](#cite-id-vm7jxmy4t7)​

Regulatory frameworks also differ internationally. The supplied descriptions identify the Australian Securities and Investments Commission (ASIC) as overseeing OTC trading in Australia and the Financial Conduct Authority (FCA) as regulating it in the United Kingdom; approaches vary across Asian jurisdictions. In wholesale energy markets, REMIT provides a separate European Union framework for reporting and market integrity.[\[13\]](#cite-id-vm7jxmy4t7)​[\[12\]](#cite-id-ciwtg638s6)​

## Historical Development

Advances in information and computer technology helped support the growth of OTC derivatives between 1980 and 2000, as financial institutions expanded their use of derivatives and managed increasingly large portfolios. In 2000, an International Monetary Fund team warned that turbulence in the late 1990s had exposed risks to financial stability arising from OTC derivatives and their markets.[\[8\]](#cite-id-4bpf0kzqk3)​

Before the 2008 financial crisis, OTC derivatives operated through networks of bilateral relationships in which counterparties’ credit exposures could change along with conditions in major asset markets. Trading in complex derivatives, including credit default swaps linked to mortgage-backed securities, played a role in the crisis. Afterward, central-counterparty clearing became more common, and regulators pressed for greater clearing and transparency.[\[8\]](#cite-id-4bpf0kzqk3)​[\[7\]](#cite-id-8p13xtery2)​

Off-exchange trading also grew in U.S. equities: it represented approximately 16% of U.S. stock trades in 2008 and about 40% by April 2014. In 2021, the Pink Sheets market faced heightened regulatory scrutiny. In 2022, Vanguard stopped permitting purchases and transfers into most OTC securities, citing their risks, low liquidity, and potential for fraud.[\[8\]](#cite-id-4bpf0kzqk3)​
