Dealer, bilateral, and electronic trading outside a formal exchange, used across bonds, equities, currencies, swaps, and other instruments.
The over-the-counter market, or OTC market, is a trading structure in which instruments are negotiated or executed outside a formal exchange, often through dealers, broker-dealers, electronic platforms, or direct bilateral relationships. OTC markets are used for many bonds, currencies, swaps, loans, and some equities.
OTC does not mean unregulated, informal, or limited to small-company stocks. The rules, transparency, execution method, clearing, and risks depend on the instrument, participants, jurisdiction, and platform.
Government, municipal, corporate, mortgage-backed, and other bonds frequently trade through dealers. A dealer can buy from a customer into inventory, sell from inventory, or locate another counterparty. Bond quotations can use price, yield, spread, or another convention, so the quote basis and accrued interest treatment must be confirmed.
Some equities that are not listed on a national securities exchange are quoted or traded through broker-dealers and electronic systems. Issuer reporting, quotation eligibility, public information, liquidity, and investor protections vary. An OTC quotation is not an exchange listing and does not guarantee current issuer disclosure.
Exchange-listed stocks can also have off-exchange executions through market makers or alternative trading systems under applicable rules. “OTC stock” and “off-exchange trade in a listed stock” are related but not identical concepts.
Much of the foreign-exchange market operates through banks, dealers, electronic platforms, and bilateral relationships rather than one centralized exchange. Spot, forward, swap, and option transactions can have different settlement, credit, margin, and documentation structures.
Swaps, forwards, and options can be negotiated bilaterally or executed through regulated platforms. Standardized classes can be subject to central clearing and trade-execution requirements, while other contracts remain bilateral. The master agreement, collateral terms, netting rights, valuation process, and applicable clearing mandate are central to risk analysis.
Syndicated loans, private securities, and other claims can transfer through assignments, participations, or negotiated sales. Consent, eligibility, confidentiality, and transfer restrictions can limit market access and liquidity.
A simplified dealer-market transaction can proceed as follows:
The dealer can act as principal, taking the other side of the trade, or as agent, seeking another party. Compensation can appear as a commission, markup, markdown, spread, fee, or trading profit depending on the transaction.
Assume a dealer quotes a corporate bond at:
Bond prices are often quoted as a percentage of face value. In this simplified example, a customer buying at the 98.75 ask pays:
$100,000 x 98.75% = $98,750
That amount is before accrued interest, fees, and any other settlement adjustments. A customer selling at the 98.25 bid would receive $98,250 before adjustments. The $500 difference between the two simplified amounts reflects the quoted spread for that face amount, not necessarily the dealer’s final profit.
The quote may change for a larger order, a different settlement date, or changing market conditions. A small reported trade at 98.50 does not guarantee that $100,000 face amount is available at that price.

OTC is not automatically more or less liquid than exchange trading. Major currency or government-bond markets can be deep, while a small listed stock can be illiquid. The instrument and transaction size matter more than the label alone.
Regulation depends on product and jurisdiction.
“Not exchange-traded” should never be used as shorthand for “not regulated.”
Issuers and counterparties can have financing or hedging needs that do not fit a listed contract. OTC structures can accommodate different notionals, maturities, currencies, covenants, payment dates, or collateral terms.
Dealers can provide immediacy by using inventory or balance sheet when matching buyers and sellers directly would be difficult. That service has a cost and depends on dealer capacity.
Some markets developed around large bilateral trades and dealer relationships rather than retail-sized exchange orders. Electronic trading can automate quotation and matching without converting the venue into a formal exchange.
OTC systems can facilitate trading in securities that are not exchange-listed. Lack of listing can also mean less public information, weaker liquidity, or transfer restrictions, so the instrument must be evaluated rather than relying on venue label.
For a customized derivative, the legal documents and valuation model can matter more than an indicative market quote.
