Quant Chalkboard: A New Way to Aggregate
The Gumbel copula is the best way to aggregate losses in economic capital, says Yimin Yang, Director of Model Risk and Capital Management Practice at Protiviti, a global consulting firm. “This copula has asymmetrical behaviour and can model fat tails the best” of the numerous copulas he has tried recently. He was speaking at a GARP webinar on August 20, 2013. Yang began by explaining that a copula was a broad class of mathematical function that could be used to describe the joint distribution function between two or more other functions. Such a joint cumulative distribution function (CDF) must determine […]

How New Regulations Are Breaking Down Silos. Part 3: Interconnection Needed
The biggest hurdle to breaking down silos “is organizational in nature,” according to Amit Gupta, Partner in Risk Management Practice at the consulting firm Accenture. “The heads of Risk, Finance, Operations are all different people and this introduces a level of complexity.” However, “organizational interconnection at high levels is starting to happen.” Gupta was the third panellist to weigh in at the GARP webinar on May 21, 2013 on how new financial regulations (Dodd-Frank and Basel III) are breaking down silos in risk management. Regulators are pushing for greater consistency in reporting. As an example, Gupta pointed to new requirements […]
How New Regulations Are Breaking Down Silos. Part 2: Look at Economics
An institution “needs to have a strong cross-risk function which coordinates all parties in order to influence the recovery plan,” said Dr. Andrea Burgtorf, Head of Stress Testing, Risk Analytics and Instruments at Deutsche Bank. She was speaking at the GARP webinar on May 21, 2013 about the effect of new regulations on risk management. As part of the Basel III mandate to develop a Recovery and Resolution Plan, a bank must include analysis of all critical economic functions, and this, said Burgtorf, “forces a bank to examine what are its core and non-core businesses, and to decide which governance […]
Monitoring Risk While Pursuing High Returns: The Importance of Being Quantitative
“A quantitative model provides a very different insight than a rating,” said Rajan Singenellore, Global Business Manager of Risk & Valuations at Bloomberg. Models are based on objective inputs and usually publicly available information, whereas ratings are based on subjective factors and inside information. Singenellore was speaking about quantitative models as the second part of a two-part webinar presentation “Monitoring Risk While Pursuing High Returns” on March 7, 2013 organized by the Global Association of Risk Professionals (GARP). “A quantitative model lets you understand risk drivers and sensitivities,” he said, such as the effects of input changes on default risk […]
Monitoring Risk While Pursuing High Returns: Who Pays the Piper?
“Rating biases affect how we think about methodologies,” said Elliot Noma, Managing Director at Garrett Asset Management. “A rating agency paid by the issuer will likely give the firm the benefit of the doubt,” whereas a rating agency paid by the investor might want to more stringently evaluate the firm. “Both evaluations have the risk of error” due to bias. Noma was speaking about evaluation of credit risk as part of the webinar presentation “Monitoring Risk While Pursuing High Returns” on March 7, 2013 organized by the Global Association of Risk Professionals (GARP). He began by dividing non-structured credit exposure […]
The Fed, Foreign Banks and Basel III: Part 1. A Long Hard Look
Foreign banking operations (FBOs) in the United States are about to face a whole new set of regulations that may dampen their enthusiasm for US-based operations, according to a February 14, 2013 webinar organized by the Global Association of Risk Professionals (GARP). “The Fed observed over time that US branches were increasingly used to fund the home office operations,” said Charles Horn, partner at Morrison Foerster, who was the first speaker at the panel. Other concerns of the Federal Reserve Board are the increased complexity of FBOs, and “the availability of home country financial resources for branch offices.” The goal, […]
The State of the Credit Markets: Part 2. Global Trends
“Political uncertainty creates a bimodal distribution of risk, which is very difficult for the markets to price,” said Seth Rooder, Global Credit Derivatives Product Manager for Bloomberg, and the second of two speakers at the Global Association of Risk Professionals (GARP) webinar on November 15, 2012. (Click here to view Part 1.) Rooder was referring to the first of five main themes in global risk trends, as he sees them.
