You can't change the past, but to protect the future, NASDAQ OMX’s Brian O’Malley argues, the financial services industry needs to partner with the regulators to evaluate what went wrong, which market mechanisms worked and which did not. Best practices risk management controls, O’Malley argues, must be put in place, and followed.

The current financial crisis could be described as a disaster waiting to happen. At too many institutions the basic tenets of good long term risk management were being ignored in favour of short term profits. A lack of transparency meant many investment bank boards and executives did not fully understand the risk their firms were assuming with complex new instruments. As a result, they were not able to properly assess the return they were getting for them.

At the same time, trillions of dollars worth of risky OTC contracts were being traded and cleared bilaterally around the globe without proper risk management controls, and the regulators have been accused of being asleep at the wheel.

Opinions vary, but most observers agree on one thing. If regulated exchanges and clearing houses, with proven risk management practices, had a role in the OTC derivatives markets, the crisis would not have been as severe. Therefore, these organizations must be part of the solution.

Exchanges and clearing houses assume and manage counterparty and clearing risk. The members put up capital, and collateral is collected from the counter-parties in the form of initial margin. The exchange measures and manages intra-day risk. When market volatility increases, a variation margin call is made. The positions of firms that cannot meet the margin call are liquidated. When the circumstances require it, the exchange can tap into the shared capital and the clearing corporation’s capital.

This system worked extremely well, even during the worst days of 2008. So the question is: should OTC contracts be migrated to exchange trading and central counterparty clearing?

There are precedents for central counterparty clearing in the OTC markets. CLS Bank operates the largest multicurrency cash settlement system, eliminating settlement risk for over half the world’s foreign exchange payment instructions. In the US, fixed-income marketplace, Fixed Income Clearing Corporation, processes more than US$3.7 trillion each day in US Government and mortgage-backed securities transactions.

For the last few years, the London Clearing House has operated a clearing facility for interest rate swaps. The International Derivatives Clearing Group (IDCG) recently started clearing and settling US dollar interest rate swap futures, and Liffe’s Bclear, which already clears OTC equity derivatives, started clearing credit default swaps (CDSs).

Role of risk-mitigating technologies
Creative use of technology can also play a big role in mitigating risk. For example, a large NASDAQ OMX technology client is leveraging technology to minimize pre-trade risk. Its customers wanted a system that could automatically validate a counterparty’s collateral and filter out bids and offers from unacceptable trading firms. In practice, this meant, traders could only see bids and offers from firms with whom they had open credit lines. Considering the number of versions of the order book that need to be sent out, the challenge was to create a system that was robust but not overly expensive or complicated.

The NASDAQ OMX solution was to allow the client to send an order book to all its customers in a single encrypted message. Users have a decryption key that determines which view of the order book they are permitted to see. The client has been using this technology in Europe to help handle pre-trade risk in securities lending.

Despite these examples, some Wall Street firms are resistant to the idea of trading OTC instruments on exchanges and clearing them centrally. They argue that OTC contracts are far more flexible than standardized, exchange-traded contracts. Bilateral trading allows them to retain anonymity. OTCs can be traded electronically or by voice, and typically the larger the deal, the more likely it is to be executed over the phone. Moreover, many OTC instruments are off balance sheet products. If they are centrally cleared, they would have to put up collateral, such as treasury bills, to meet margin calls, and these would be would be an on-balance-sheet item.
