Diversifying Wildfire Risk
Climate change is altering risk profiles the world over. In the US, it has led to an increase in wildfire season length, wildfire frequency, and the size of burned area. When it comes to such disasters, is the economic risk only borne by those in the risky area, or can the economic risk be shared among investors? A recent webinar looked at a longstanding tool for financial adaptation. For nearly a century, mortgages have been used to create mortgage-backed securities (MBSs) in order to share the risk (and thus the return) of financing real estate. “What are the benefits of […]
Net-Zero Buildings
How do we build our homes and cities for a sustainable future? Climate change is such a huge, complex problem that tackling it can seem overwhelming. Fortunately, many organizations are addressing various parts of this colossal puzzle. One aspect is the “built environment.” Can existing buildings be modified to cope with climate change? Can buildings be redesigned to have net zero effect on the environment? On July 1, 2021, a panel of experts gave their thoughts on matters relating to climate change and buildings, as part of the New York Times Climate Hub series of webinars. This is the “Built […]
Missing the Mark
“In the spring a young man’s fancy lightly turns to thoughts of buying a house,” Morty said, as he put the latest issue of the Financial Analysts Journal on my desk. We don’t often paraphrase Tennyson in the office, so this caught my attention. “You’re not thinking of moving again, are you?” I said. “No, but I always keep my eye on the market,” he said. “You should check out what these economists are saying.” So I did. First I read the FHFA working paper, by the team of Alexander Bogin, William Doerner, and William Larson. “Missing the Mark: Mortgage […]
Stress Testing Mortgages. Part 2
The team of Scott L. Smith, Jesse Weiher, and Debra Fuller at the Federal Housing Finance Agency (FHFA) use specialized financial models to estimate potential losses. They carried out empirical tests of countercyclical shocks using four different models of mortgage credit risk. This posting continues a February 4, 2015, presentation by Scott L. Smith to an audience of financial risk managers at Global Association of Risk Professionals (GARP). Two models were devised at FHFA, and two are commercially available credit models: one, called Black Knight (formerly LPS-AA), and the other called ADCO Loan Dynamics. The estimated losses were converted to a capital […]
Stress Testing Mortgages. Part 1
“One needs to be careful and not over-reliant on any one model,” said Scott L. Smith, Associate Director for Capital Policy at the Federal Housing Finance Agency (FHFA). He was referring to the financial models used by major financial institutions to estimate potential losses. On February 4, 2015, he was presenting a GARP-sponsored webinar on countercyclical stress tests to set capital requirements. Smith explained how credit risk is measured for mortgages, and described a way to embed stress testing that uses countercyclical concepts. He and colleague Jesse Weiher, Senior Economist at FHFA, performed dynamic stress testing that was adjusted to […]
Stressed Interest Rates: Battle of the Models
For generating shocked interest rate curves, such as a sudden economic stress might engender, “a three-factor parameterization solves many problems—but issues remain,” said Alexander Bogin, Senior Economist at the Federal Housing Finance Agency, and the second presenter at a webinar on modelling interest rate shocks held October 28, 2014, and sponsored by the Global Association of Risk Professionals. To develop an improved yield curve approximation, Bogin showed three variants of non-linear Laguerre functions of time to maturity. These were the Nelson-Siegel model (which has 3 factors); the Svensson model (4 factors); and the Björk-Christensen model (5 factors). Over a two-year […]
Basel III Standardized: Avoid the Showstopper
“If you can’t comply, it could be a showstopper,” said Henry Fields, Partner at Morrison & Foerster LLP, who was the first of two panellists at a webinar held on September 16, 2014, organized by the Global Association of Risk Professionals. The purpose of the webinar was to discuss the Basel III Standardized Approach for mid-tier banks (assets of over $500 million), and Fields began by giving an overview. The potential “showstopper” would be non-compliance with the new rules for risk weights for assets that are scheduled to come into effect January 1, 2015. “When the Fed issued the [new] […]
Counterparty Credit Risk 2. The Good, the Bad, the Ugly, and the Unseen
“Data and its accuracy are key to making this work,” said Robert Scanlon, referring to counterparty credit risk. Scanlon is the former Group Chief Credit Officer of Standard Chartered Bank and current Principal, Scanlon Associates. As the second of three speakers at a GARP webinar on counterparty risk held on May 20, 2014, Scanlon spoke from years of experience with risk practices. First, the good part of calculating counterparty credit risk. Scanlon said there is plenty of data already, especially for consumer/retail transactions. “You can start with a steady state assumption and get more data as time goes on. Ask […]
Eye on Credit Markets. Part 2: Spreads Hit Floor
“The central bank stimulus has been significant—what will happen as it’s withdrawn?” asked Seth Rooder, Global Credit Derivatives Product Manager at Bloomberg. He was the second of two speakers to consider the effects of tapering in a GARP webinar presentation on November 21, 2013. A key question is: “when will the Fed taper?” Rooder said not soon, because with unemployment still above 6.5 percent, Vice-Chair of the Fed Janet Yellen will have unwillingness to taper. Currently, the Fed is pumping money into the system by buying $40 billion in mortgage-backed securities and $45 billion in Treasury bills per month. He […]
Americans Among Us. Part 2.
When it comes to US-Canada cross-border tax planning, a suggested rule of thumb is “to plan as if the US spouse is the spender and the Canadian spouse is the one saving assets,” said Christine Perry, lawyer at Keel Cotrelle LLP, during the second half of a seminar at the CFA Society Toronto offices on October 29, 2013. Perry identified eight common issues in cross-border tax planning that she encounters. Her list began with wills that are drafted in contemplation of “only” Canadian law, “which I see two or three times a month,” and moved on to issues involving gifts, […]
