What it means
Unlike major stock exchanges where shares trade in a centralised location with public prices, the over-the-counter market operates through a phone and digital network. Dealers act as market makers, quoting prices at which they are willing to buy and sell specific assets.
This setup allows companies that are too small or do not meet strict regulatory requirements to have their shares traded publicly. For non-finance managers, understanding this market is vital because it handles many specialised financial products, such as foreign exchange contracts and interest rate swaps, which businesses use to manage risk.
Because transactions happen directly between parties rather than through a public exchange, terms are flexible and tailored to the exact needs of the businesses involved. However, this flexibility comes with downsides.
The lack of a central marketplace means prices are less transparent, and finding a buyer or seller can take longer. Regulatory oversight is generally lower compared to major exchanges, which increases counterparty risk, meaning you must trust that the other party will fulfil their side of the financial agreement.
Imagine buying a used car. A major stock exchange is like a busy official car auction where prices are called out publicly.
The over-the-counter market is like buying a car through private classified ads or direct negotiation, where you talk directly to the seller to agree on a price.
In practice
Real-world examples
Example 1
A growing tech startup with 40 employees chooses to have its shares traded on an over-the-counter platform, allowing early investors and employees to sell their stock before qualifying for a major public exchange. A dealer quotes bid and ask prices, and trades are agreed directly. The company enjoys more liquidity without the full cost of a listing.
Example 2
A mid-sized manufacturing company uses the over-the-counter market to buy a custom currency forward contract, locking in a specific exchange rate to protect its profit margins on future overseas equipment purchases. The contract is tailored to the exact amount and date of the payment. A standard exchange product would not have matched either.
Example 3
A local property developer buys a bespoke interest rate swap from a commercial bank via an over-the-counter desk, capping their floating loan payments at a 5% rate to protect cash flow against rising rates. The bank takes the other side of the trade. The developer must therefore consider the bank's credit strength.

Formula
Calculation
Spread = Ask Price - Bid Price. Spread % = Spread / Ask Price.
Worked example: a dealer quotes a stock at a buying price (bid) of $4.80 and a selling price (ask) of $5.00, so the spread is 5.00 - 4.80 = $0.20 per share. This spread represents the dealer's profit margin for facilitating the trade.
As a percentage, the spread is 0.20 / 5.00 = 4%. If you bought 10,000 shares at $5.00 and immediately sold them back at the $4.80 bid, you would lose 10,000 x 0.20 = $2,000 before any other costs. Spreads tend to be wider on thinly traded over-the-counter stocks than on large exchange-listed shares.Case study
Seen in the real world
This is a fictional, illustrative scenario. BrightLight Electronics, a mid-sized US manufacturer, wanted to protect its upcoming supply chain costs from currency fluctuations. The firm received an invoice for 75,000,000 yen from a Japanese supplier, payable in six months. Worried that the dollar might fall against the yen, making the parts much more expensive, BrightLight approached a commercial bank's over-the-counter desk.
The bank structured a bespoke currency forward contract allowing BrightLight to lock in an exchange rate of 150 yen per dollar today, regardless of market movements in six months. That fixed the cost at 75,000,000 / 150 = $500,000. When the payment date arrived, the spot rate had dropped to 140 yen per dollar, so buying the yen at market would have cost 75,000,000 / 140 = about $535,700. Because BrightLight used the over-the-counter contract, they saved approximately $35,700, securing their profit margins for the year.
The finance director was careful to explain the other side of the trade to the board. Had the rate moved to 160 yen per dollar, the market cost would have been only 75,000,000 / 160 = $468,750, and the firm would have given up roughly $31,250 of potential gain. The contract was bought for certainty, not for profit, and the director also reviewed the bank's credit standing because the deal carried counterparty risk.
Watch out
Common mistakes
- Assuming over-the-counter stocks are always high-risk scams or penny stocks.

- Expecting the same fast execution speeds and price transparency as major exchanges.
