Regulation of OTC Derivatives Market

Regulation of OTC Derivatives Market

After completing this reading, you should be able to:

  • Summarize the clearing process in OTC derivative markets.
  • Describe changes to the regulation of OTC derivatives that took place after the 2007-2009 financial crisis and explain the impact of these changes.

Failure to manage and mitigate market liquidity risk in derivatives markets can have disastrous consequences in global financial markets. Following the 2007/2009 financial crisis, a trove of regulatory initiatives commenced, aimed at narrowing the regulatory gap between the OTC (Over-the-counter) market and the exchange-traded market. Notably, leaders from the G20 group of nations agreed to have almost all derivatives traded on exchanges or electronic trading platforms and cleared through a central counterparty. In this chapter, we delve into the clearing process of OTC derivatives and look at regulatory changes that have since been introduced in an attempt to increase transparency and reduce risk.

Over-the-counter Trading vs. Exchange Trading

The over-the-counter market is a decentralized trading platform, without a central physical location, where market participants use a host of communication channels to trade with one another without a formal set of regulations. The communication channels commonly used include telephone, email, and computers. OTC trading is facilitated by a derivatives dealer who usually is a major financial institution specializing in derivatives.

In an OTC market, it’s possible for two participants to exchange products/securities privately without others being aware of the terms, including the price. OTC markets are much less transparent than exchange trading.

Stocks traded in an OTC market could belong to a small company that’s yet to satisfy the conditions for listing on the exchange. The OTC market is also popular for large trades.

Advantages of OTC Markets over Exchanges Include:

  • There are fewer restrictions and regulations on trades.
  • The participants have the freedom to negotiate deals.
  • It’s cost-effective for corporates as service costs are lower.
  • There’s better information flow between a market maker and the customer thanks to one-on-one contact.

Disadvantages of OTC Markets Compared to Exchanges Include:

  • There’s increased credit risk associated with each OTC trade.
  • Less transparency.

The Clearing Process in OTC Derivative Markets

Clearing is the procedure by which derivative trades settle, that is, the correct and timely transfer of funds between the buyer and the seller.

There are two main approaches: bilateral clearing and central clearing.

In a bilateral clearing, trades are agreed upon bilaterally between a buyer and a seller with the contract typically taking the form of an ISDA Master Agreement (ISDA stands for International Swap and Derivatives Association). A section of this agreement, called the credit support annex, outlines all collateral arrangements agreed to between the buyer and seller. This part outlines the acceptable forms of collateral, the collateral that should be posted by each side (if any), and also haircuts that could be applied.

The main body of the ISDA agreement then outlines systematically how to proceed in the event that one of the parties defaults. In this regard, defaulting could be either failing to make payments as they fall due, or failing to post collateral as initially agreed.

Trades settled bilaterally are referred to as non-cleared OTC trades.

Since they are negotiated bilaterally, non-cleared trades often lack market uniformity and rank very low in terms of transparency. What’s more, the absence of complex regulation means counterparties can get into complex trades that do not have strict collateral requirements, which leads to higher counterparty risk.

In a central clearing, the entire process is handled by a central counterparty that provides services similar to those offered by a fully-fledged exchange clearinghouse. When two parties, A and B agree to transact, they are required to present the OTC derivative to the CCP for clearing. If the CCP accepts it, the CCP becomes an interposed intermediary and enters offsetting transactions with the two parties.

Example: CCP Clearing

Suppose two companies, A and B get into an interest rate swap agreement where A pays a fixed rate of 3% to company B on a principal of $100 million for a period of 3 years, while B pays LIBOR to Company A on similar terms (same period, same principal). If a CCP accepts the transaction, two separate trades are immediately created. On one hand, company A will have a transaction with the CCP where it will pay 3% and receive LIBOR on $100 million. On the other, company B will have a transaction with the CCP where it will pay LIBOR and receive 3%, again, on $100 million. This implies that A and B will not have credit exposure to each other.

CCP ClearingCCP clearing means that a CCP becomes the legal counterparty to each trading party, providing a guarantee that it will honor the terms and conditions of the original trade even in the event that one of the parties defaults before the discharge of its obligations under the trade. To be able to do this, the CCP collects enough money from each party which goes toward covering potential losses that may be incurred if a party fails to follow through on the initial agreement.

The following view, although a bit simplistic, helps to further demonstrate the role played by CCPs in trading by contrasting non-cleared trades (left) with cleared trades (right). Each of the six entities denoted B represents a dealer bank.

From this view, we can see two advantages of having CCPs in financial markets:

  • A CCP reduces the interconnectedness within financial markets. This way, even if one of the dealers defaults, the impact on other participants is minimal.
  • There’s increased transparency on the role and positions of each participant.
  • CCPs introduce operational efficiency by reducing the number of transactions to be settled.

The legal process by which a CCP interposes itself between the buyer and the seller is referred to as contract novation. The CCP becomes a buyer to every seller and a seller to every buyer. In essence, novation replaces one “direct” contract with another indirect contract. This implies that the initial contract between counterparties ceases to exist, and the counterparties no longer have counterparty risk with respect to one another. It’s the CCP that bears the counterparty risk. However, the CCP bears not the net market risk, which remains with the original parties to the trade.

In the years leading up to the 2007/2009 financial crisis, about 75% of OTC transactions involved bilateral arrangements. Only 25% involved central clearing. Post-crisis measures being put in place are aimed at reversing these percentages to have most OTC transactions cleared through a CCP. However, the process might take some time because the complex nature of some transactions prevents them from being cleared. Bilateral transactions have the upper hand because they give room for creativity and freedom to trade in complex derivatives. In addition, it has been argued that CCPs are not immune from financial strain. By handling a large number of transactions, CCPs result in the concentration of risk, and the failure of just a single CCP could have serious consequences that could stretch beyond the derivatives industry.

The few transactions that are exempted from the ongoing reforms include nonstandard transactions, select foreign exchange transactions, and trades involving non-financial entities.

Margining

In order to have effective risk control over the trade, the CCP requires each party to post collateral that can be seized in the event of default. The initial margin must be posted when initiating the contract. Typically, the initial margin is set such that it is 99% certain to cover market moves over a 5-day period. If the equity in the initial margin account falls below the maintenance margin, the relevant party receives a margin call, a requirement to provide additional funds to restore the margin account to the initial level.

Sometimes, the margining securities may be subject to a haircut. This means that the market value of the securities is reduced to determine their value for margin purposes. For example, a T-bond might be subject to a 5% haircut, implying that, if its market value were $100, it would cover only $95 of a margin requirement.

The amount payable to restore the initial margin to the required amount is called the variation margin. The variation margin is settled daily, usually in cash. If a member fails to provide the required variation margin, the CCP closes out its transactions with that member. Margin requirements can be settled either using cash or treasury instruments. The CCP pays interest on cash balances.

Initial margin requirements may frequently change to reflect market conditions. However, it’s imperative to note that the initial margin does not depend significantly on the creditworthiness of the party posting it. A party with a good credit rating may be required to post as much initial margin as another party with a not-so-good credit rating.

Example: Margin Call

A firm has entered a short futures contract to sell 5,000 barrels of crude oil for $50 per barrel. The initial margin is $10,000 and the maintenance margin is $8,000.

a) What price change would lead to a margin call?

There is a margin call whenever more than $2,000 is lost from the margin account. For this to happen, the futures price of crude oil has to rise by more than 2,000/5,000 = $0.4. Therefore, there’s a margin call when the futures price of crude oil rises above $50.40 per barrel.

b) Under what circumstances would $2,500 be withdrawn from the margin account?

Withdrawal from the margin account would only happen if the futures price of crude oil falls by 2,500/5,000 = $0.2. This translates to a fall in price to $49.8 per barrel.

Notable Differences between Exchange Futures Transactions and OTC Transactions

One important difference between a futures (exchange) transaction and a typical OTC transaction is that the former is settled daily, while the latter involves payments only on specified days. What’s more, following an increase in the futures price and subsequent flow of cash margin from the house member with a short position to the exchange clearinghouse, the margin no longer belongs to the clearinghouse member and no longer earns interest. In OTC markets, the transfer of cash variation margin from party A to party B, through the CCP, results in party A earning interest and party B paying interest on the funds transferred.

Closing Out

Just like in exchange transactions, OTC transactions involve members contributing to a default fund. If a party to a transaction is not a member of the CCP, they are allowed to clear transactions through members. Whenever a member fails to post margin when required, they are declared defaulters and their positions are closed out. In the process of closing out, the CCP may incur a loss. The party to bear the loss is determined by way of a waterfall, in the following order:

  1. The initial margin of the defaulting member.
  2. The default fund contribution of the member.
  3. The default fund contributions of other members.
  4. The CCP’s equity.

Netting

Netting refers to the treatment of all transactions between two parties as a single transaction either when calculating collateral requirements or processing early terminations following a default event. Netting reduces credit risk because it rules out a situation where a member defaults on out-of-the-money positions while continuing to honor positions that are in the money. Furthermore, netting can reduce the initial margin required.

Example: Netting

Party A has two transactions with party B: an interest rate swap worth $100 million and an oil futures contract worth -$60 million. For purposes of calculating the initial margin, the two transactions are combined to form a single transaction worth $40 million.

How Defaults are Handled

In the event of a default or bankruptcy, derivatives transactions are treated differently from other transactions. For example, ISDA master agreements contain an early termination provision that takes precedence over bankruptcy rules. This provision states that, if there is an “event of default,” the non-defaulting party has the right to terminate all transactions with the defaulting party after a short period of time has elapsed. Moving quickly is aimed at recouping as much as possible from the defaulting member before the situation turns detrimental. Events that constitute default are failure to make payments, failure to post collateral, or declaration of bankruptcy.

Another key difference between derivatives transactions and non-derivative transactions is that the non-defaulting party can bypass court orders and take immediate possession of collateral posted by the defaulting party.

Following a default event, the non-defaulting party calculates the mid-market value of outstanding transactions. The party is then allowed to adjust these transactions in its favor by half the bid-offer spreads on the transactions for the purposes of calculating the settlement amount. The adjustment is some sort of compensation in recognition of the fact that the party will have to replace the transactions by trading with other dealers and it will have to be subject to their bid-offer spreads when that happens.

Example: Valuing a Derivative Transaction Following a Default Event

A transaction has a mid-market value of $50 million to the non-defaulting party and the transaction is bid $47 million, offering $53 million. For purposes of settlement, what will be the value of the transaction?

Solution

For purposes of settlement, the transaction will be valued at $53 million — the cost that would be incurred replacing the transaction. If the non-defaulting party had the other side of the transaction so that its mid-market value was -$50 million, it would be valued at -$47 million for settlement purposes, recognizing the fact that a third party would be prepared to pay only $47 million to take the defaulting party’s position.

Post-crisis Regulatory Changes

As noted earlier, the OTC derivatives market took a sizeable share of the blame after the 2007/2009 financial crisis. The crisis has over time led to many regulations to enhance the clearing process and strengthen collateral requirements. Leaders from the G20 group of nations came up with three major changes:

    1. A requirement that all standardized OTC derivatives be cleared through CCPs: Before 2015, most OTC transactions were bilateral and did not involve central clearing. This meant that an initial margin was generally not required. Under the new regulations, a big percentage of OTC transactions have to be cleared through a CCP, and both initial and variation margins have to be provided by both parties. Complex transactions cleared bilaterally between financial institutions will be subject to the same collateral requirements as those cleared through CCPs.
    2. A requirement that standardized OTC derivatives be traded on electronic platforms: The move is aimed at increasing the level of transparency in the market. By matching buyers and sellers through an electronic system available to every participant (and potential participants), there will be price transparency. These platforms have been named swap execution facilities(SEFs) in the United States and organized trading facilities (OTFs) in Europe.
    3. A requirement that all trades in the OTC market be reported to a central trade repository: The goal here is to provide regulators with a regular and reliable stream of information about the goings-on in the market. This will help them to continually monitor the risks being taken by participants.

The other notable regulation that has been introduced has altered the pool of assets that can be posted as collateral. Most of the collateral required will have to be in form of cash or treasury instruments to enhance liquidity. Banks will be required to hold liquid assets that are sufficient to meet any margin calls (which have to be met immediately).

Impact of Post-crisis Changes

The new developments have resulted in some sort of convergence of ORTC and exchange-traded markets:

  • OTC trading platforms have become more like organized exchanges.
  • OTC clearing process now looks more like the clearing process through a clearing house.
  • The percentage of OTC trades marked “standard” is likely to increase, blurring the distinction between OTC instruments and exchange-tradable instruments.
  • OTC transactions still cleared bilaterally will continue more like exchange-tradable transactions because they will have to provide an initial margin, posted to a third party. The initial margin must cover, with 99% certainty, market moves during a 10-day period of stressed market conditions.
  • Increased regulatory oversight over OTC markets has resulted in increased competition between the OTC market and organized exchanges. To beat the competition, some exchanges have resorted to offering less standard products to institutional investors.

Convergence has brought the issue of rehypothecation to focus.  In this case, a dealer using collateral posted with it by one counterpart uses the same collateral to satisfy a collateral demand by another counterpart. In 2007, there was about $4 trillion of collateral but this was created from just $1 trillion of collateral through rehypothecation.

Under new Basel Committee rules, traders will be allowed to rehypothecate the initial margin only once, and even then, certain conditions will have to be met. Variation margin can be rehypothecated.

Practice Question

What is the difference between using an ISDA master agreement and using a CCP for clearing over-the-counter transactions?

A. When an ISDA agreement is used, each party has to provide both the initial margin and the variation margin; when a CCP is used, no margin is required from either party.

B. When an ISDA agreement is used, there are no collateral arrangements between parties; when a CCP is used, parties must agree on the acceptable forms of collateral.

C. When an ISDA agreement is used, the credit support annex outlines the steps to be followed when a party defaults; when the CCP is used, the probability of counterparty default is zero.

D. When an ISDA agreement is used, counterparties have counterparty risk with respect to one another; when the CCP is used, it assumes all of the counterparty risk.

The correct answer is: D.

When an ISDA agreement is used, each party is exposed to counterparty risk. Each side takes the risk that the other side will default. CCP clearing, on the other hand, means that the CCP becomes the legal counterparty to each trading party, providing a guarantee that it will honor the terms and conditions of the original trade even in the event that one of the parties defaults before the discharge of its obligations under the trade.

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
