Topology Can Streamline Modelling
How can software systematize and optimize the routine tasks in building financial risk models? “We use topology to inform feature selection, and then we examine a range of models,” said Mukund Ramachandran, Data Scientist at Ayasdi. He was the third of three panellists at the October 27, 2015, webinar on Effective Risk Models Using Machine Intelligence sponsored by the Global Association of Risk Professionals. In the course of evaluating potential models, several statistical tests are applied. “Machine intelligence considers the entire high dimensional space jointly,” he said. Machine learning is capable of applying hundreds of algorithms and different combinations, “but […]
Swaps, Before & After
“Historically, there were few, if any, regulatory requirements on swaps … it was effectively an unsecured loan,” said James Schwartz, Of Counsel at Morrison & Foerster. He was the fourth and final presenter at the Derivatives Regulatory Update webinar held on March 31, 2015, sponsored by the Global Association of Risk Professionals. Prior to the Dodd-Frank Act, swaps dealers were self-regulated through the trade association International Swaps and Derivatives Association (ISDA). “It was typical for the two parties to accept a certain amount of uncollateralized exposure to each other in the form of a threshold that varied according to their […]
Update on Central Clearing
One of the goals of the Dodd-Frank Act is to mitigate systemic financial risk by establishing a central clearinghouse for derivatives. But how close is the financial community toward achieving that goal? “Many swaps were not collateralized prior to Dodd-Frank,” said Julian E. Hammar, Of Counsel at Morrison & Foerster. Hammar was the third of four presenters at the Derivatives Regulatory Update webinar held on March 31, 2015, sponsored by the Global Association of Risk Professionals. Clearing swaps mitigates risk not just through requiring margin collateral (and thereby reducing) credit risk. It also imposes an “operational discipline” Hammar said, with […]
“Skin in the Game”
What safeguards should be in place, to minimize the risks posed by financial derivatives? CME Group requires that its Clearing Members support the risk of their portfolios by “putting some skin in the game,” said Jason Silverstein, Executive Director and Associate General Counsel of CME Group, a body that includes the Chicago Mercantile Exchange and the New York Mercantile Exchange among its subsidiaries. “It’s a story of balancing incentives, in order to stabilize losses. Our belief is that it should be significant and risk-based.” Silverstein was the second of four presenters at a webinar titled Derivatives Regulatory Update held on […]
Towards Reducing Systemic Risk
Have the risks posed by financial derivatives in the context of the current, still evolving, regulatory landscape been properly addressed? Michael Piracci, Director of PCB Compliance at Barclays, said that nowadays he has “a lot of interactions day-to-day with the clearinghouse” and overall, “it makes me feel a little more comfortable there’s a good system in place.” Piracci was the first of four presenters at a webinar titled Derivatives Regulatory Update held on March 31, 2015, sponsored by the Global Association of Risk Professionals. Piracci began by explaining the role of the Central Counterparty (CCP) and the Futures Commission Merchants […]
When Data Is Sparse. Part 2
It’s difficult to model sovereign credit risk for emerging markets using structural models such as the Merton model because “calibration is always an issue,” said Rob Stamicar, Senior Director of Research in Multi-Asset Class Risk Management at Axioma, continuing a theme during the second half of his webinar on December 2, 2014. During the first half, he showed how the probability of default can be used as a common link among the asset classes of interest (bonds, swaps, and equities). In the second half, he focused more on sovereign credit risk. Calculation of sovereign risk could be done directly, “but […]
When Data Is Sparse. Part 1
When modelling risk in emerging markets, are you hampered by sparse data? “Relationships between different asset classes can help measure the sovereign risk in emerging markets,” said Rob Stamicar, Senior Director of Research in Multi-Asset Class Risk Management at Axioma. He was sole presenter at a webinar on December 2, 2014, sponsored by the Global Association of Risk Professionals. When modelling global multi-asset class portfolios, “aggregation can be challenging,” said Stamicar, because the FX rates must also be taken into consideration—the subject for another day. His talk focussed on three asset classes: equity, fixed income, and credit portfolios. Infrequent data, […]
Swap Data Reporting
One of the primary purposes of swap data reporting, as explained by James Schwartz, Counsel at Morrison & Foerster LLP, is to permit regulators to identify the swap exposures of market participants—which they found themselves unable to do during the financial crisis. Schwartz spoke as part of a four-person panel on challenges to risk data aggregation, reporting and recordkeeping organized by GARP on July 22, 2014. Schwartz gave an overview of the US swap data reporting requirements under the Dodd-Frank Act. “It’s important to note timing,” he said with regard to U.S. Commodity Futures Trading Commission (CFTC) regulations and Basel […]
OTC Market 2. A New Paradigm
“How will errors be handled? That’s the biggest area of discussion with SEFs,” said Bis Chatterjee, Global Head of E-Trading and New Business Development, Credit Markets, at Citigroup Global. SEF refers to a Swap Execution Facility. He was the second of two speakers at a GARP-sponsored webinar, about changes to the over-the-counter (OTC) credit default swaps (CDS) market, held on April 15, 2014. “The market had less time than it would have liked to review various rules of the new guideline,” Chatterjee said, referring to the flurry of market response to the new regulations brought in by the US Commodities Futures […]
OTC Market 1. “It was a busy 15 months…”
Over the past fifteen months, “the biggest paradigm shift that we’ve seen in the last twenty years” has occurred, said Nathan Jenner, Chief Operating Officer at Bloomberg Electronic Trading. He was the first of two speakers at a GARP-sponsored webinar, held on April 15, 2014, about changes to the over-the-counter (OTC) market. Jenner put the changes in context: the new legislation driving the changes arose from the 2009 G20 summit in Pittsburgh that occurred on the heels of the 2008 financial crisis. There were three areas the signatory nations wanted to focus on, he said: “reducing systemic risk, improving transparency, […]
