# Counterparty: Definition, Types of Counterparties, and Examples

## What Is a Counterparty?

A counterparty is the other participating party in a financial [transaction](https://www.investopedia.com/terms/t/transaction.asp). Every transaction must have a counterparty for the trade to be completed.

Financial transactions also raise the concern of counterparty risk: the possibility that the counterparty may not fulfill their obligations, particularly in over-the-counter (OTC) transactions. And in many financial transactions, the counterparty is unknown. This is where clearing firms and exchanges play a critical part, mitigating that risk as intermediaries to ensure both parties meet their obligations in the transactions.

Counterparties that can be involved in transactions include arbitrageurs, market makers, and liquidity, momentum, retail, and technical traders.

### Key Takeaways

*   Counterparties can vary widely, including individuals, businesses, governments, and other organizations, and they may enter into transactions regardless of equal standing.
*   Counterparty risk is a significant concern in financial transactions, as it involves the possibility that the counterparty may not fulfill their obligations, especially in over-the-counter (OTC) transactions.
*   Clearinghouses play a crucial role in mitigating counterparty risk in financial markets by acting as intermediaries to ensure both parties meet their contractual obligations.
*   The global financial crisis of 2008 highlighted the importance of understanding counterparty risk, with high-profile cases such as AIG's involvement in credit default swaps emphasizing the potential impacts.

## How Counterparties Function in Financial Transactions

The term "counterparty" can refer to any entity on the other side of a financial transaction. It can include deals between people, businesses, governments, or any other organization.

Also, both parties don’t need to be of equal standing. This means a person can be a counterparty to a business, and the reverse is also true. When a contract or exchange agreement happens, one party is the counterparty, or both are counterparties to each other. This also applies to [forward contracts](https://www.investopedia.com/terms/f/forwardcontract.asp) and other contract types.

A counterparty introduces [counterparty risk](https://www.investopedia.com/terms/c/counterpartyrisk.asp) into the equation. This is the risk that the counterparty will be unable to fulfill their end of the transaction.

In many financial transactions, you don’t know the counterparty, and [clearing firms](https://www.investopedia.com/terms/c/clearinghouse.asp) reduce this risk. In fact, with typical exchange trading, we don't ever know who our counterparty is on any trade, and there often will be several counterparties, each making up a piece of the trade.

## Real-World Examples of Counterparties in Transactions

In the case of a purchase of goods from a retail store, the buyer and retailer are counterparties in the transaction. In terms of financial markets, the [bond](https://www.investopedia.com/terms/b/bond.asp) seller and bond buyer are counterparties.

In certain situations, multiple counterparties may exist as a transaction progresses. Each exchange of funds, goods, or services in a transaction involves a series of counterparties. For example, if a buyer purchases a retail product online to be shipped to their home, the buyer and retailer are counterparties, as are the buyer and the delivery service.

In a general sense, anytime one party supplies funds, or items of value, in exchange for something from a second party, counterparties exist. Counterparties reflect the dual-sided nature of transactions.

## Different Types of Counterparties in Financial Markets

Counterparties in a trade can be classified in several ways. Having an idea of your potential counterparty in a given environment can provide insights into how the market is likely to act based on your presence/orders/transactions and other similar style traders. Here are just a few prime examples:

*   **Retail traders**: These are ordinary individual investors or other nonprofessional traders. They may be trading through an online broker like E-Trade or a voice broker like Charles Schwab. Often, retail traders are seen as desirable counterparties since they are assumed to be less informed, have less sophisticated trading tools, and are willing to buy at the offer and sell at the [bid](https://www.investopedia.com/terms/b/bidprice.asp).
*   [**Market makers**](https://www.investopedia.com/terms/m/marketmaker.asp): These participants' main function is to provide [liquidity](https://www.investopedia.com/terms/l/liquidity.asp) to the market, yet they also attempt to profit from the market. They have massive market clout, and will often be a substantial portion of the visible bids and offers displayed on the books. Profits are made by providing liquidity and collecting [ECN](https://www.investopedia.com/terms/e/ecn.asp) rebates as well as moving the market for [capital gains](https://www.investopedia.com/terms/c/capitalgain.asp) when circumstances dictate a profit may be capturable.
*   **Liquidity traders**: These are non–market makers who generally have very low fees and capture daily profits by adding liquidity and capturing the ECN credits. As with market makers, they may also make capital gains by being filled on the bid (offer) and then posting orders on the offer (bid) at the inside price or outside the current market price. These traders may still have market clout, but less so than market makers.
*   **Technical traders**: In almost any market, there will be [traders](https://www.investopedia.com/terms/t/trader.asp) who trade based on chart levels, whether from market indicators, [support and resistance](https://www.investopedia.com/trading/support-and-resistance-basics/), trend lines, or chart patterns. These traders watch for certain conditions to arise before stepping into a position; in this way, it is likely they can more accurately define the risks and rewards of a particular trade. At commonly known technical levels, the liquidity traders and [designated market makers](https://www.investopedia.com/terms/d/designated-market-maker-dmm.asp) may become technical traders, although not always in the way expected—designated market makers may falsely trigger technical levels [knowing large groups of traders will be affected, thus churning large amounts of shares](https://www.investopedia.com/articles/active-trading/102914/technical-analysis-strategies-beginners.asp).
*   **Momentum traders**: There are different types of [momentum](https://www.investopedia.com/terms/m/momentum.asp) traders. Some will stay with a momentum stock for multiple days (even though they only trade it intraday), while others will screen for "stocks on the move," constantly attempting to capture quick, sharp movements in stocks during news events, [volume](https://www.investopedia.com/terms/v/volume.asp), or price spikes. These traders typically exit when the movement is showing signs of slowing—this type of strategy demands controlled decision making, [requiring a continual refinement of entry and exit techniques](https://www.investopedia.com/articles/trading/03/092403.asp).
*   [**Arbitrageurs**](https://www.investopedia.com/terms/a/arbitrageur.asp): Using multiple assets, markets, and statistical tools, these traders attempt to exploit inefficiencies in the market or across markets. These traders may be small or large, although certain types of arbitrage trading will require large amounts of buying power to fully capitalize on inefficiencies. Other types of "arbitrage" may be accessible to smaller traders, such as when dealing with highly correlated instruments and short-term deviations from the correlation threshold.  
    

## Understanding Counterparty Risk and Its Implications

In dealings with a counterparty, there is an innate risk that one of the entities involved will not fulfill their obligation. This is especially true for [over-the-counter (OTC)](https://www.investopedia.com/terms/o/otc.asp) transactions. Examples include the risk that a vendor will not provide a good or service after the payment is processed, or that a buyer will not pay an obligation if the goods are provided first. It can also include the risk that one party will back out of the deal before the transaction occurs but after an initial agreement is reached.

In structured markets like stocks or [futures](https://www.investopedia.com/terms/f/futures.asp), clearinghouses and [exchanges](https://www.investopedia.com/terms/e/exchange.asp) reduce counterparty risk. When buying a stock, you don’t need to worry about the other party’s financial status. The clearinghouse or exchange steps up as the counterparty, guaranteeing the stocks you bought or the funds you expect from a sale.

Counterparty risk gained greater visibility in the wake of the 2008 [global financial crisis](https://www.investopedia.com/articles/economics/09/financial-crisis-review.asp). AIG famously leveraged its AAA [credit rating](https://www.investopedia.com/terms/c/creditrating.asp) to sell (write) [credit default swaps (CDS)](https://www.investopedia.com/terms/c/creditdefaultswap.asp) to counterparties who wanted default protection (in many cases, on [collateralized debt obligation (CDO)](https://www.investopedia.com/terms/c/cdo.asp) tranches). When AIG could not post additional collateral and was required to provide funds to counterparties in the face of deteriorating [reference obligations](https://www.investopedia.com/terms/r/reference-obligation.asp), the U.S. government bailed it out.

## What Does Counterparty Mean?

A counterparty is simply the other participant in a transaction—for every buyer, there is a seller. Every transaction requires at least two parties, whether it be buying stocks or purchasing groceries at a local supermarket.

## What Is Counterparty Risk?

Counterparty risk is the risk that the other party in the transaction will not honor the agreement and fulfill its side of the deal. Fortunately, in financial markets, this isn't often an issue, as counterparty risk is transferred to clearinghouses.

## Who Is the Counterparty in a Loan?

If you take out a loan, the main counterparty would be the financial institution lending you money.

## The Bottom Line

A counterparty is the other participant in any financial transaction. It can include deals between individuals, businesses, governments, or any other organization.

Understanding counterparty risk—the risk that the other side of the trade will be unable to fulfill their end of the transaction—is crucial, especially in scenarios like over-the-counter (OTC) transactions.

Clearinghouses play a vital role in managing counterparty risk, helping to mitigate this risk in structured markets such as stocks and futures. Clearinghouses and exchanges function as intermediaries in financial transactions, overseeing transactions and ensuring that both the buyer and the seller honor their contractual obligations.

The AIG case is an example of the impact of counterparty risk during the 2008 global financial crisis.

Individuals should engage with financial institutions or entities that effectively manage counterparty risk, and should remain mindful of who their counterparties are in any financial dealings, as well as the potential risks involved.
