What Is It?
Over-the-counter (OTC) markets are decentralized trading venues where participants trade directly with each other rather than through a centralized exchange. Bonds, derivatives, and many international securities trade OTC.
Origin
OTC trading predates exchanges—early securities traded informally between merchants. Formal OTC markets developed for bonds, derivatives, and unlisted stocks. Electronic platforms (TradeWeb, MarketAxess) modernized OTC trading. Post-2008 regulations mandated clearing for many OTC derivatives.
Why It Matters
OTC markets dominate fixed income, derivatives, and foreign exchange. They offer flexibility but less transparency than exchanges. Understanding OTC mechanics is essential for trading these markets. Counterparty risk and liquidity vary significantly.

Market Mechanics
OTC trades are negotiated bilaterally or through dealer networks. Price discovery occurs through quotes, indications of interest, or electronic platforms. Settlement may be bilateral or through clearing houses. Documentation (ISDA master agreements) standardizes terms.
How It Behaves
Liquidity varies by instrument and market conditions. Dealer balance sheets constrain market making. Electronic platforms increase transparency and competition. Clearing mandates reduce counterparty risk but add complexity. Voice trading persists for complex or large trades.
