Over-the-counter (finance)

Over-the-counter (finance) is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Over-the-counter (finance) rather than just read about it. In short: Over-the-counter (OTC) or off-exchange trading or pink sheet trading is done directly between two parties, without the supervision of an exchange. It is contrasted with exchange trading, which occurs via exchanges.

Key takeaways

  • Over-the-counter (finance) belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Over-the-counter (finance) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Over-the-counter (finance) from memory before moving on to harder problems.

Reference excerpt

Over-the-counter (OTC) or off-exchange trading or pink sheet trading is done directly between two parties, without the supervision of an exchange. It is contrasted with exchange trading, which occurs via exchanges. A stock exchange has the benefit of facilitating liquidity, providing transparency, and maintaining the current market price. In an OTC trade, the price is not necessarily publicly disclosed. OTC trading, as well as exchange trading, occurs with commodities, financial instruments (including stocks), and derivatives of such products. Products traded on traditional stock exchanges, and other regulated bourse platforms, must be well standardized. This means that exchanged deliverables match a narrow range of quantity, quality, and identity which is defined by the exchange and identical to all transactions of that product. This is necessary for there to be transparency in stock exchange-based equities trading. The OTC market does not have this limitation. Parties may agree on an unusual quantity, for example in OTC, market contracts are bilateral (i.e. the contract is only between two parties), and each party could have credit risk concerns with respect to the other party. The OTC derivative market is significant in some asset classes: interest rate, foreign exchange, stocks, and commodities. In 2008, approximately 16% of all U.S. stock trades were "off-exchange trading"; by April 2014, that number increased to about 40%. Although the notional amount outstanding of OTC derivatives in late 2012 had declined 3.3% over the previous year, the volume of cleared transactions at the end of 2012 totalled US$346.4 trillion. The Bank for International Settlements statistics on OTC derivatives markets showed that "notional amounts outstanding totalled $693 trillion at the end of June 2013... The gross market value of OTC derivatives – that is, the cost of replacing all outstanding contracts at current market prices – declined between end-2012 and end-June 2013, from $25 trillion to $20 trillion."

Stocks

In the United States, over-the-counter trading in stock is carried out by market makers using inter-dealer quotation services such as OTC Link (a service offered by OTC Markets Group). Although exchange-listed stocks can be traded OTC on the third market, it is rarely the case. Usually OTC stocks are not listed nor traded on exchanges, and vice versa. Stocks quoted on the OTCBB must comply with certain limited U.S. Securities and Exchange Commission (SEC) reporting requirements. The SEC imposes more stringent financial and reporting requirements on other OTC stocks, specifically the OTCQX stocks (traded through the OTC Market Group Inc). Other OTC stocks have no reporting requirements, for example Pink Sheets securities and "gray market" stocks. However, in 2021, the pink sheets market came under the spotlight of greater regulatory scrutiny. Some companies, with Wal-Mart as one of the largest, began trading as OTC stocks and eventually upgraded to a listing on fully regulated market. In a 2017 Kiplinger Personal Finance article, Dan Burrows wrote that American OTC markets are rife with penny stock fraud and other risks, and should generally be avoided by investors "with the exception of large, established foreign firms". Reputable companies located outside the U.S., he notes, sometimes sell stock over-the-counter to gain access to American markets while avoiding the expense of keeping two sets of audited paperwork to be listed on multiple stock exchanges (one in their homeland or to international standards, and one for American standards).

Contracts An over-the-counter is a bilateral contract in which two parties (or their brokers or bankers as intermediaries) agree on how a particular trade or agreement is to be settled in the future. It is usually from an investment bank to its clients directly. Forwards and swaps are prime examples of such contracts. It is mostly done online or by telephone. For derivatives, these agreements are usually governed by an International Swaps and Derivatives Association agreement. This segment of the OTC market is occasionally referred to as the "Fourth Market". Critics have labelled the OTC market as the "dark market" because prices are often unpublished and unregulated. Over-the-counter derivatives are especially important for hedging risk in that they can be used to create a "perfect hedge". With exchange traded contracts, standardization does not allow for as much flexibility to hedge risk because the contract is a one-size-fits-all instrument. With OTC derivatives, though, a firm can tailor the contract specifications to best suit its risk exposure.

Counterparty risk and potential fraud OTC derivatives can lead to significant risks. Especially counterparty risk has gained particular emphasis due to the 2008 financial crisis. Counterparty risk is the risk that a counterparty in a derivatives transaction will default prior to expiration of the trade and will not make the current and future payments required by the contract. There are many ways to limit counterparty risk. One of them focuses on controlling credit exposure with diversification, netting, collateralisation and hedging. Central counterparty clearing of OTC trades has become more common in recent years, with regulators placing pressure on the OTC markets to clear and display trades openly. In their market review published in 2010, the International Swaps and Derivatives Association examined OTC Derivative Bilateral Collateralization Practice as one way of mitigating risk. As of 2022, The Vanguard Group no longer permits purchases and transfers in of most over-the-counter securities., noting that they "are prone to high risk, low liquidity, and potential fraud."

Worked examples

Example 1 — a first encounter with Over-the-counter (finance)

Start with the simplest possible case. Write down what Over-the-counter (finance) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Over-the-counter (finance) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Over-the-counter (finance) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Over-the-counter (finance)

In research
Over-the-counter (finance) appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Over-the-counter (finance) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Over-the-counter (finance) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Derivatives (finance), Electronic trading, Financial markets, so understanding it makes those chapters shorter.
In everyday life
Look for Over-the-counter (finance) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
