Previous studies report that option implied volatility varies across moneyness, maturity, and time, yet, once the level is controlled for, the shape of the volatility surface relative to the volatility implied for at-the-money (ATM) option is stable even over the period of the 1987 stock market crash. This study examines the dynamics of the implied volatility surface for euro-US dollar options, using a recently developed panel cointegration test that allows multiple structural breaks while accounting for cross-sectional dependence. In the model, the option implied volatility Is specified as a quadratic function of ATM volatility, spot and forward rates. The three factors together account for 98 percent of variations in the option implied volatilities across five moneyness, five maturities and over eight years of daily observations from Jan. 2006 to Dec. 2014. The estimated volatility surface however is not stable over time. Rather, its relationship with the three underlying factors exhibits substantial changes around the periods of the Global Financial Crisis and subsequent Euro-zone crisis. This finding is in a stark contrast to previous studies which report the shape of volatility surface is stable over time.","PeriodicalId":40006,"journal":{"name":"Journal of Derivatives","volume":"22 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2015-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87577868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chow","doi":"10.2139/SSRN.2142458","DOIUrl":"https://doi.org/10.2139/SSRN.2142458","url":null,"abstract":"Dealing with default risk on sovereign debt became an urgent matter with the Financial Crisis of 2008. Depending on both exogenous and endogenous factors, the risk of eventual default may become significant over the lifetime of a loan. Creditors are then faced with a dilemma, since they cannot force the borrowing country into bankruptcy court. Should they ease repayment by reducing the principal of the debt (“forgiveness”), or should they offer an extra award if the borrower repays in full? The latter award could come in the form of lower borrowing costs in the future. In this article, Sun and Chen propose to model the possibility of loan modification for risky sovereign debt as a kind of down-and-in put option: There is a boundary value (the “default threshold”) for the country’s perceived ability to pay, measured as the ratio of debt principal to GDP, at which the terms of the debt are revised, either to reduce the principal or to offer a repayment award. Both approaches have been tried in practice. What the authors show is that forgiveness is better for the creditors than a repayment award. The sensitivity of bond value to default boundary, forgiveness amount, and repayment award within the model are explored through simulation. The authors then conduct an empirical analysis on the bonds of 17 of the G20 countries to estimate the values of these three model parameters, and show that their model performs well in practice.","PeriodicalId":40006,"journal":{"name":"Journal of Derivatives","volume":"24 1","pages":"67-95"},"PeriodicalIF":0.7,"publicationDate":"2013-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82290956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide three ways of modelling such correlation: (1) asset value follows a diffusion process with a one-time jump (such as currency devaluation) at the time of credit default; (2) Default intensity and asset price are driven by correlated Brownian motions in addition to the jump; (3) Default time and future asset price are correlated through a copula. When both asset price and credit default are independent of interest rates, such contract can be valued on a two-dimensional lattice (or finite-difference grid) in the second approach. We show that for a large class of one-factor default rate models, the computation can be reduced to one-dimension, a property often reserved for the affine class of models. We also obtain analytical solutions if default hazard rate, asset price return, and the copula are all Gaussian. Our experience shows that valuation is much more sensitive to the first and third type of correlations. We apply the model to the valuation of extinguishable FX swaps that terminate upon a credit event and quanto credit default swaps where premium and protection legs are paid in different currencies.","PeriodicalId":40006,"journal":{"name":"Journal of Derivatives","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2013-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89950779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Klein, Jun Yang","doi":"10.2139/SSRN.1600911","DOIUrl":"https://doi.org/10.2139/SSRN.1600911","url":null,"abstract":"One of the many counterintuitive things students in a first course on options learn is that premature exercise of an American call option on a nondividend paying stock is a mistake, and that for a dividend-paying stock, early exercise is never rational except just before the stock goes ex-dividend. Efforts to incorporate counterparty credit risk in the calculation have suggested assuming no change in exercise policy and simply discount the projected future cash flows at a higher risky interest rate. Others have argued that counterparty default should never happen with American options because the holder will exercise just before the counterparty defaults and effectively step in front of the other creditors to be paid in full. Klein and Yang show that these ideas are incorrect. Early exercise gives up the option’s time value, so that even when imminent counterparty default is perfectly predictable, there is still a cost to exercise for credit reasons. Moreover, properly taking counterparty risk into account leads to optimal exercise behavior different from that in the nonvulnerable case, so simply discounting the same cash flows at a different rate undervalues the vulnerable option. The difference is particularly important when counterparty risk is wrong-way risk, such that the counterparty’s credit weakens under the same conditions that the option is in the money.","PeriodicalId":40006,"journal":{"name":"Journal of Derivatives","volume":"18 1","pages":"7-21"},"PeriodicalIF":0.7,"publicationDate":"2013-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78769169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But returns processes more realistic than lognormal diffusions with constant parameters easily create difficulties for them. One of the most important extensions of the Black-Scholes paradigm is to allow stochastic volatility, but even nonstochastic timevarying volatility destroys the important property that the tree recombines, which limits the growth in the number of nodes as time advances. Stochastic volatility introduces a second random variable, which then requires adding another dimension to the tree, under the constraint that the return and volatility changes must maintain the same degree of correlation as in the data. The Heston model features correlation in return and volatility shocks, but building it into a lattice is tricky. In this article, Ruckdeschel, Sayer, and Szimayer develop a lattice method that begins with a binomial tree for the volatility and a trinomial tree for stock price, and then connects them in such a way that the empirical degree of correlation between return and volatility is maintained. Efficiency relative to existing methods is increased, and in some cases it is possible to improve performance further by matching higher moments as well.","PeriodicalId":40006,"journal":{"name":"Journal of Derivatives","volume":"27 1","pages":"9-29"},"PeriodicalIF":0.7,"publicationDate":"2013-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81318998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
