Should Derivatives Be Privileged in Bankruptcy?

Derivatives enjoy special status in bankruptcy: they are exempt from the automatic stay and effectively senior to virtually all other claims. We propose a corporate finance model to assess the effect of these exemptions on a firm's cost of borrowing and incentives to engage in derivative transactions. While derivatives are value‐enhancing risk management tools, seniority for derivatives can lead to inefficiencies: it transfers credit risk to debtholders, even though this risk is borne more efficiently in the derivative market. Seniority for derivatives is efficient only if it provides sufficient cross‐netting benefits to derivative counterparties that provide hedging services.     

Intermarket efficiency: An application of interbattery APT to mortgage-backed securities

Increasing popularity of investments in mortgage-backed securities has led to closer integration of the mortgage market into traditional capital markets. Using monthly returns during 1982–1988 for common stocks, Treasury bonds and GNMA and FHLMC mortgage-backed securities, the interbattery factor analytic Arbitrage Pricing Theory of (Cho, 1984) is used to test five hypotheses for intramarket and intermarket integration. Results indicate that three to five common factors are found within the same security market, while only one to three factors are found common between different markets.The APT could not be rejected within the same security market, but was rejected in most intermarket comparisons. While risk-free rates are found to differ between markets, the risk premium tests are conclusive indicators of integration. Our results support claims that the stock, bond, and the mortgage-backed securities markets are integrated.     

Valuing futures and options on volatility

This paper presents simple closed-form expressions for volatility futures and option prices and examines their implications for the characteristics of these securities. We show that the properties of these volatility derivatives are fundamentally different from those of conventional option and futures contracts. This analysis also provides insights into the role that volatility derivatives may play in managing and hedging volatility risk in financial markets.     

From subordination to parity: an international comparison of equity securities law claims in insolvency proceedings

Securities law claims in insolvency proceedings raise important questions of allocation of risk and remedies. In the ordinary course of business, equity claims come last in the hierarchy of claims during insolvency. What is less clear is whether this should encompass claims arising from the violation of public statutes designed to protect equity investors. Discerning the optimal allocation of risk is a complex challenge if one is trying to maximize the simultaneous advancement of securities law and insolvency law public policy goals. From a securities law perspective, there must be confidence in meaningful remedies for capital markets violations if investors are to continue to invest. From an insolvency perspective, creditors make their pricing and credit availability choices based on certainty regarding their claims and shifting those priorities may affect the availability of credit. The critical question is the nature of the claim advanced by the securities holder and whether subordination of securities law claims gives rise to inappropriate incentives for corporate officers within the insolvency law regime. A comparative analysis reveals that the U.S. has provided a limited statutory exception to complete subordination through the fair funds provision of the Sarbanes-Oxley Act by allowing SEC claims for penalties and disgorgement to rank equally with unsecured claims even though the funds are distributed to shareholders. The U.K. and Australian schemes permit shareholders to claim directly as unsecured creditors for fraudulent acts and misrepresentation by the issuer. In contrast, Canadian law is underdeveloped in its treatment of such claims. The paper canvasses the policy options available to reconcile securities law and insolvency law claims, including a discussion of the appropriate gatekeeping role for regulatory authorities and the courts, and the need for a framework that offers fair and expeditious resolution of such claims. If the public policy goal of both securities law and insolvency law is to foster efficient and cost-effective capital markets, it seems that the systems need to be better reconciled than currently. The paper also examines the codified response to the time and resources consumed in various common law tracing claims by customers in a securities firm insolvency.

The rise of China's securitization market

We study the development of asset securitization markets in China. We manually collect all asset securitization projects and securities data from 2005 to 2015. Inspection of this sample combined with related policy changes reveals distinct characteristics and some potential problems. At the macro level, asset securitization market in China is policy driven, regulation‐segmented, and highly illiquid. At the micro level, the underlying assets are mainly corporate loans or assets, rather than mortgage or consumption loans as in the US and European markets. State owned commercial banks and enterprises enjoy significantly lower interest rates when issuing securitization bonds. Finally, risk‐isolation and credit enhancing techniques significantly improve the rating of asset‐backed securities.     

Mapping the UK interbank system

We present new evidence on the structure of interbank connections across key markets: derivatives, marketable securities, repo, unsecured lending and secured lending. Taken together, these markets comprise two networks: a network of interbank exposures and a network of interbank funding. Network structure varies across and within these two networks, for reasons related to markets’ different economic functions. Credit risk and liquidity risk therefore propagate in the interbank system through different network structures. We discuss the implications for financial stability.     

Extreme observations and risk assessment in the equity markets of MENA region: Tail measures and Value-at-Risk

The standard “delta-normal” Value-at-Risk methodology requires that the underlying returns generating distribution for the security in question is normally distributed, with moments which can be estimated using historical data and are time-invariant. However, the stylized fact that returns are fat-tailed is likely to lead to under-prediction of both the size of extreme market movements and the frequency with which they occur. In this paper, we use the extreme value theory to analyze four emerging markets belonging to the MENA region (Egypt, Jordan, Morocco, and Turkey). We focus on the tails of the unconditional distribution of returns in each market and provide estimates of their tail index behavior. In the process, we find that the returns have significantly fatter tails than the normal distribution and therefore introduce the extreme value theory. We then estimate the maximum daily loss by computing the Value-at-Risk (VaR) in each market. Consistent with the results from other developing countries [see Gencay, R. and Selcuk, F., (2004). Extreme value theory and Value-at-Risk: relative performance in emerging markets. International Journal of Forecasting, 20, 287–303; Mendes, B., (2000). Computing robust risk measures in emerging equity markets using extreme value theory. Emerging Markets Quarterly, 4, 25–41; Silva, A. and Mendes, B., (2003). Value-at-Risk and extreme returns in Asian stock markets. International Journal of Business, 8, 17–40], generally, we find that the VaR estimates based on the tail index are higher than those based on a normal distribution for all markets, and therefore a proper risk assessment should not neglect the tail behavior in these markets, since that may lead to an improper evaluation of market risk. Our results should be useful to investors, bankers, and fund managers, whose success depends on the ability to forecast stock price movements in these markets and therefore build their portfolios based on these forecasts.     

A note on the importance of overnight information in risk management models

This paper examines the economic value of overnight information to users of risk management models. In addition to the information revealed by overseas markets that trade during the (domestic) overnight period, this paper exploits information generated via recent innovations in the structure of financial markets. In particular, certain securities (and associated derivative products) can now be traded at any time over a 24-h period. As such, it is now possible to make use of information generated by trading, in (almost) identical securities, during the overnight period. Of the securities that are available over such time periods, S&P 500 related products are by far the most actively traded and are, therefore, the subject of this paper. Using a variety of conditional volatility models that allow time-dependent information flow within (and across) three different S&P 500 markets, the results show that overnight information flow has a significant impact on the conditional volatility of daytime traded S&P 500 securities. Moreover (time-consistent) forecasts from models that incorporate overnight information are shown to have economic value to risk managers. In particular, Value-at-Risk (VaR) models based on these conditional volatility models are shown to be more accurate than VaR models that ignore overnight information.     

Statement of the Financial Economists Roundtable* Reforming the OTC Derivatives Markets

In investigations of the causes of the crisis, a major focus has been the role of derivative securities, particularly credit-default swaps (CDS). Despite widespread claims to the contrary, however, the 51 economists who signed this statement begin by asserting that CDS and other derivatives contracts were not a primary cause of the financial crisis. At the same time, derivatives markets are said to play an important economic role by shifting risks from businesses and individual investors to parties more willing (and generally better able) to bear them. But, as illustrated during the crisis, derivatives also can be used to transmit risk in ways that have the potential to pervade the entire financial system. With the aim of limiting systemic risk associated with the use of derivatives, the statement recommends the following:

• • measures that encourage migration of more derivatives transactions to central-clearing facilities, including higher capital requirements and stricter criteria (including segregation) for the collateralization of positions that are not cleared;
• • data reporting and repository requirements designed to help regulators and market participants to understand systemic risk exposures in the financial system;
• • post-trade price transparency for all sufficiently standardized OTC products;
• • continued migration of trading in actively traded OTC products to exchanges.

Finally, although the economists support regulations against market manipulation, they oppose potential restrictions on speculative trading, including the holding of “naked” CDS, while affirming that both hedging and speculation are important and socially beneficial activities in our financial system.     

The performance of hedge funds and mutual funds in emerging markets

Use of short selling and derivatives is limited in most emerging markets because such instruments are not as readily available as they are in developed capital markets. These limitations raise questions about the value added provided by hedge funds, especially compared to traditional mutual funds active in these markets. We use five existing performance measurement models plus a new asset-style factor model to identify the return sources and the alpha generated by both types of funds. We analyze subperiods, different market environments, and structural breaks. Our results indicate that some hedge funds generate significant positive alpha, whereas most mutual funds do not outperform traditional benchmarks. We find that hedge funds are more active in shifting their asset allocation. The higher degree of freedom that hedge funds enjoy in their investment style might thus be one explanation for the differences in performance.     

Treasury Safety,Liquidity, and Money Premium Dynamics: Evidence from Debt Limit Impasses

Treasury securities enjoy a “money premium” because they are ultra-safe and liquid. However, during debt limit impasses, the safety and liquidity of Treasury securities temporarily deteriorate, eroding the money premium. Using past impasses, we find the money premium eroded by roughly six basis points across all Treasury securities and up to 50 basis points for the shortest maturities at the greatest risk of a delayed principal payment. Safety and liquidity each accounted for about half of the erosion. The deterioration of safety and liquidity also appears to interact, consistent with theories of default-driven liquidity risk and the information sensitivity of debt.     

Aggregate implications of indivisible labor, incomplete markets, and labor market frictions

We study the impact of tax and transfer programs on steady-state allocations in a model with search frictions, an operative labor supply margin, and incomplete markets. In a benchmark model that has indivisible labor and incomplete markets but no trading frictions we show that the aggregate effects of taxes are identical to those in the economy with employment lotteries, though individual employment and asset dynamics can be different. The effect of frictions on the response of aggregate hours to a permanent tax change is highly nonlinear. There is considerable scope for substitution between “voluntary” and “frictional” nonemployment in some situations.     

Risk and Regulation in Derivatives (or Why Derivatives Are a Blessing,Not a Curse)

In this article, first published in 1994, the authors aimed to defuse the widespread hysteria about derivatives fueled by media accounts (like Fortune magazine's cover story in the same year) by offering a systematic analysis of the risks to companies, investors, and the entire financial system associated with the operation of the relatively new derivatives markets. Such analysis ended up providing assurances like the following:

• As long as most companies are using derivatives mainly to limit their financial exposures and not to enlarge them in efforts to pad their operating profits, reported losses on derivatives should not be a matter for concern. “Complaining about losses on a swap used to hedge a firm's exposure,” as the authors note, “is like objecting to the costs of a fire insurance policy if the building doesn't burn down.”
• To the extent that companies are using derivatives to hedge—and what evidence we have suggests that most are—the default risk of derivatives has been greatly exaggerated. An interest rate swap used by a B‐rated company to hedge a large exposure to interest rates will generally have significantly less default risk than a AAA‐rated corporate bond issue.
• Thanks to the corporate use of derivatives, much of the impact of economic shocks such as spikes in interest rates or oil prices is being transferred away from the hedging companies to investors and other companies better able to absorb them. And in this fashion, defaults in the economy as a whole, and hence systemic risk, are effectively being reduced, not increased, through the operation of the derivatives markets.

Moreover, the authors warn in closing that the likely effect of then proposed derivatives regulation would be to restrict access to and increase the costs to companies of using derivatives markets. As one example, the excessive capital requirements associated with derivatives facing bank dealers—based on gross rather than net measures of exposure—and which regulators have since proposed extending to nonbank dealers—were expected to have the unintended effect of encouraging dealers to sell precisely the kinds of riskier, leveraged derivatives that Bankers Trust sold Procter & Gamble, and that functioned as Exhibit A in the Fortune article.

Integration of Trans-Atlantic Capital Markets, 1790-1845

During the 1790s, European investors began to purchase substantial quantities of US government and corporate securities. A number of these securities were traded in markets on both sides of the Atlantic. Based on market price quotations we compiled for the same securities in London and New York markets, we ask if these early trans-Atlantic securities markets were integrated, and, if so, when they became integrated. We find little evidence of market integration before 1816, and substantial evidence of it thereafter. Financial globalization - the convergence of financial asset prices in markets on different continents - began earlier than most have suspected.     

Does OTC derivatives reform incentivize central clearing?

Regulatory changes in the over-the-counter (OTC) derivatives market seek to reduce systemic risk. The reforms require that standardized derivatives be cleared through central counterparties (CCPs), and they set higher capital and margin requirements for non-centrally cleared derivatives. We investigate whether these requirements create a cost incentive in favor of central clearing, as intended. We compare the total capital and collateral costs when banks transact fully bilaterally and when they clear all contracts through CCPs. We calibrate our model using data on the OTC market collected by the Federal Reserve. We find that the cost incentive may not favor central clearing. The main factors driving the cost comparison are netting benefits, the margin period of risk, and CCP guarantee fund requirements. Lower guarantee fund requirements lower the cost of clearing but make CCPs less resilient.     

Do ADRs enhance portfolio performance for a domestic portfolio? Evidence from the 1990s

American depository receipts (ADRs) represent an increasingly popular and convenient mechanism for international investing. We analyze ADRs traded throughout the 1990s and find that these securities offer a diversification and portfolio performance benefit when combined with a domestic portfolio (proxied by the S&P 500). While we find that emerging market ADRs are effective instruments for reducing portfolio risk, they do not improve portfolio performance as measured by the Sharpe ratio. Developed market ADRs do improve portfolio performance as measured by the Sharpe ratio. The asset allocation which maximizes the Sharpe ratio is 84 percent domestic stocks, 16 percent developed ADRs, and 0 percent emerging ADRs. Further, due to problems in defining an appropriate market index for ADRs, the Sharpe ratio is viewed to be the preferred performance measure. Other measures such as Jensen’s alpha and the Treynor measure are susceptible to being “gamed” to distort portfolio performance.     

Who makes on-the-run Treasuries special?

The most recently issued, on-the-run, Treasuries are extremely liquid and frequently trade at a premium in both the cash and repo, or financing, markets. Previous research suggests that both the cash and repo premiums reflect demand from buy-and-hold investors who value the superior liquidity of these securities and are reluctant to lend them in the repo market. We find evidence that premiums in the repo market are also closely related to market participants’ demand to hedge interest rate risk associated with their holdings of fixed income securities.     

International Portfolio Investment: Theory, Evidence, and Institutional Framework

At first sight, the idea of investing internationally seems exciting and full of promise because of the many benefits of international portfolio investment. By investing in foreign securities, investors can participate in the growth of other countries, hedge their consumption basket against exchange rate risk, realize diversification effects and take advantage of market segmentation on a global scale. Even though these advantages might appear attractive, the risks of and constraints for international portfolio investment must not be overlooked. In an international context, financial investments are not only subject to currency risk and political risk, but there are many institutional constraints and barriers, significant among them a host of tax issues. These constraints, while being reduced by technology and policy, support the case for internationally segmented securities markets, with concomitant benefits for those who manage to overcome the barriers in an effective manner.
