Regulatory Capital Decisions in the context of Consumer Loan Portfolios
BY Kanshukan Rajaratnam
Associate Professor of Finance at University of Cape Town


ABSTRACT: A topic of interest in recent literature is regulatory capital requirements for consumer loan portfolios. Banks are required to hold regulatory capital for unexpected losses, while expected losses are to be covered by either provisions or future income. In this paper, we show the set of efficient operating points in the market-share and profit space for a portfolio manager operating under Basel II capital requirement and under capital constraints are a union of single-cutoff score and double-cutoff score operating points. For a portfolio manager increasing market-share beyond the maximum allowable under a single-cutoff score policy (e.g., with binding capital constraints), is required to grant loans to high risk applicants. We show this results in greater portfolio risk but without an increase in regulatory capital requirement amount. The increase in forecasted losses is assumed to be absorbed by provisions or future margin income. Given portfolio managers take on higher risk under the same regulatory capital amount, our findings call on greater focus on provision amounts and future margin income under the supervisory review pillar of Basel II.

The Provost's Lecture Series on Women in Leadership

Babbio 122

The Provost’s Lecture Series on Women in Leadership is designed to showcase the achievements of prominent and successful women and to motivate the next generation of leaders. It provides an opportunity for women to share their individual experiences and to analyze the unique strengths, challenges and opportunities they face. The women selected for this series are true visionaries from which we can all learn.

The journey to founding start-up Saladax Biomedical was no linear path for Adrienne Choma. After obtaining her J.D. from NYU, Ms. Choma started her career at a traditional pharmaceutical corporation. Ms. Choma thrived in the pharmaceutical industry and held a variety of senior leadership positions at three corporations throughout the course of her career. At each turn along the way, Ms. Choma gained key insights into what it takes to succeed in corporate America while also gaining a depth of knowledge of the inner workings of the pharmaceutical industry. Ms. Choma shares this journey with us, exploring each of the formative drivers in the process of her career as she discovered her own characteristics in becoming an entrepreneur and founder of Saladax Biomedical.

Join Ms. Choma on April 1 as she shares her experience as a guide for what awaits each of us along our own entrepreneurial journeys.

Start your journey at the Provost's Lecture Series, registration required.

Attendance for this event is open to all Stevens faculty, students, staff and invited guests.

Stochastic Models in Financial Engineering

BY Zhenyu Cui
Assistant Professor - Department of Mathematics
Brooklyn College of City University of New York

ABSTRACT: In this talk, I shall give an overview of my previous and current research and publications in stochastic models and their applications in financial engineering. First, I shall introduce the stochastic volatility model based on time-homogeneous diffusions and discuss the deterministic criteria for the martingale property of the underlying, and the pricing of volatility derivatives (variance swap, timer option). Then I shall talk about my current research on flexible premium variable annuities(FPVA), which are popular investment products for retirement planning. A fast and accurate analytical approximation is developed for pricing FPVAs by drawing on its connection to Asian options. The study can help providers of FPVA estimate the magnitude of underpricing when offering these products. 

BIOGRAPHY: Zhenyu Cui is currently an assistant professor at department of mathematics, Brooklyn College of City University of New York since August 2013. He graduated with a Ph.D. In Statistics under the supervision of Carole Bernard and Don McLeish from the University of Waterloo in July 2013. During his graduate study, he was awarded the Bank of Montreal Capital Markets Advanced Research Scholarship. He has published his research in Mathematical Finance, Journal of Economic Theory, Finance and Stochastics, Journal of Computational Finance, etc. His research proposals “Impact of flexible periodic premiums on variable annuity guarantees”(Co-PIs: C. Bernard, S. Vanduffel) and “Modeling and risk management of variable annuities with VIX-linked fee structure”(Co PIs: R. Feng, A. MacKay) have been funded through the 2014-2015 and the 2015-2016 Society of Actuaries Individual Grant Competition.

FE SEMINAR: Agostino Capponi "Price Contagion through Balance Sheet Linkages"

Price Contagion through Balance Sheet Linkages
BY: Agostino Capponi, Assistant Professor, Columbia University              

ABSTRACT:  We study price linkages between assets held by financial institutions that are required to maintain fixed capital requirements over time. We consider a market consisting of a banking and nonbanking sector. Firms in the banking sector actively manage their leverage ratios to conform with pre-specified target levels. Our analysis suggests that regulatory policies aimed at stabilizing the system by imposing capital constraints on banks may have unintended consequences: banks’ deleveraging activities may amplify asse return shocks and lead to large fluctuations in realized returns. The same mechanism can cause spill-over effects, where assets held by leverage targeting banks can experience hikes or drops caused by shocks to otherwise unrelated assets held by the sam banks.  Such fire-sale externalities are produced if leverage targeting banks become too large relative to the nonbanking sector, as measured by elasticity-weighted assets. 

We show that these effects can be mitigated by encouraging banks to implement asset allocation strategies with higher exposure to liquid, rather than illiquid, assets.

BIO:

Currency Investing: A Risk Premium Approach

BY: Aysu Secmen, Assistant Professor, Columbia University

ABSTRACT:  The asset allocation decision is one of the key decisions an investor has to make. In this presentation, we review the traditional asset allocation paradigm, where equity market risk overwhelmingly dominates in terms of contribution to portfolio risk. We then move on to describe an increasingly relevant paradigm for asset allocation, centered around the concept of risk premia. Finally, we focus our attention on the risk premium approach to currency investing and the ability of currencies to bring diversification to traditional portfolios. We present an extended back-test of currency risk premia, supporting the case for FX strategies as an independent source of robust long-term returns.

BIO: Aysu Secmen is a former director and North America head for the Citi Investment Strategies in the Multi-Asset Group. She was previously the global head of Quantitative Investor Solutions team in Citi Foreign Exchange, focusing specifically on the design of rule-based strategies in the FX space.
