The Information Content of Basel III Liquidity Risk Measures

Han Hong, Jing-Zhi Huang, Deming Wu

This paper examines the relationship between two liquidity measures and the probability of bank failures. It finds that the Liquidity Coverage Ratio (LCR) is positively related to bank failures and that the Net Stable Funding Ratio (NSFR) is negatively correlated. As expected less stable funding for a bank indicates higher risk of bank failure. However, the positive correlation of the Liquidity Coverage Ratio to bank failures associates bank failures with more liquidity. The authors hypothesize that this is due to hoarding of liquid assets in times of financial stress.

Reducing Retirement Risk with a Rising Equity Glide-Path

Wade Pfau, Michael Kitces

The authors come up with a counterintuitive solution for managing the glide path of an in-retirement portfolio. Rather than the conventional decreasing equity allocation, this study argues that an increasing equity allocation actually lowers the risk of portfolio failure. Using this approach, several scenarios can be considered. If the stock market drops at the beginning of retirement, than the rising allocation puts more capital to work in an asset that has a depressed price and is likely to appreciate. If equities rise considerably at the beginning of the retirement period, then the portfolio is unlikely to run out of money anyway, and more risk can be taken.

CoCos: A Primer

Stefan Avdjiev, Anastasia Kartasheva, Bilyana Bogdanova

This paper introduces the mechanics behind a recent hybrid security, contingent convertible capital instruments, known as CoCos. CoCos are debt instruments issued by banks that absorb losses when capitalization levels fall too low. The market for such securities is still small, with only $70 billion worth of CoCos issued since 2009 compared to over $4 trillion of other debt instruments.

Corporate Hedging and Corporate Governance: The Role of the Board and the Audit Committee

Vivian V. Tai, Yi-Hsun Lai, Tung-Hsiao Yang, Min-The Yu

The authors examine the relationship between quantifiable board structure metrics and leverage and risk metrics. Corporate governance is measured by such metrics as larger boards, more audit committee members, or more independent directors. In general, companies with better corporate governance hedge more risks and have lower risk ratios.

Gold, Oil, and Stocks

Jozef Barunik, Evzen Kocenda, Lukas Vacha

The correlations between gold, oil, and stocks since 1987 appears to remain largely zero until the past decade, when the three assets all started to become positively correlate with each other. This pattern is true for correlations over various time frames including daily and monthly price data.

Tax Risk and Corporate Cash Holdings

Michelle Hanlon, Edward L. Maydew, Daniel Saavedra

Because corporate tax payments can be questioned by governments for several years, companies’ are at risk of being charged more taxes than were paid. For companies that are more aggressive in their tax accounting this leads to a higher risk. The authors of this paper find that companies with more aggressive tax accounting tend to hold more cash to cover this risk.

A Weighted Mean Model for Operational Risk Assessment

Yundong William Huang, Murphy Smith, David Durr

Understanding a firm’s operational risk is both important to managing the organization and difficult to measure. A simple model is proposed to avoid the issues that come with models that are theoretically sound, but impractical to use for many companies.

A Practical Approach to the Vexing Issue of ‘Risk Appetite’

Various methods for quantifying enterprise risk exist. However, to some extent the uncertainty of an organization is determined by the risk appetite of its managers, which is difficult to quantify. This paper discusses risk appetite in relation to organizations and how it can be assessed.

Funding Cost and a New Capital Model

Lincoln Hannah

Typical derivative funding models include two components, a market rate, such as LIBOR, and a bank’s cost of borrowing added on. A new model is proposed which replaces both components with one. This funding cost is based on expected loss rather than the probability of default.

Measuring Credit Risk in a Large Banking System: Econometric Modeling and Empirics

Andre Lucas, Bernd Schwaab, Xin Zhang

The authors create two measures of financial systemic risk based on the likelihood of simultaneous financial institution failure. The model is inspired by the Merton model, the idea that the risk of a firm can be measured by considering the company’s equity as an option on its assets.

Robustness and Informativeness of Systemic Risk Measures

Gunter Loffler & Peter Raupach

Loffler & Raupach examine several proposed risk metrics for financial institutions; Marginal expected shortfall, Conditional Value at Risk (CoVaR), and Tail-Risk Gamma. They find several theoretical cases where these metrics would misrepresent the true risk of an institution.
