While a decline in the market value of sovereign assets (below a benchmark level of liabilities) can trigger sovereign distress/default risk, volatility in sovereign assets can increase the risk premium on domestic debt and credit spread on external debt. These can escalate the probability of...

This paper considers recent derivatives mismarking cases from Bacon 1996 and Truelove and Steel 1997 through to Piper 2009 and Montserret 2009. The behavioural, institutional, risk-reward and regulatory drivers of these cases are reviewed as well as associated derivatives mismarking techniques...

We study the information content of foreign exchange (FX) option volume using a unique dataset on over-the-counter FX options with disclosed counterparty identities and contract characteristics. Our study shows that FX option volume can predict future exchange rate returns, especially when the...

We study the theoretical and empirical properties of a simple measure of market illiquidity, namely the realized Amihud, which is defined as the ratio between the realized volatility and trading volume and which refines the popular price impact measure proposed by Amihud (2002). In our model,...

According to general asset pricing theory, options should reward their holders for the systematic risk they are bearing. In this paper, we study the returns of foreign exchange options. We find that, by sorting options according to the distance of their implied volatility from the historical...

We explain the valuation and correlation hedging of Foreign Exchange Basket Options in a multi-dimensional Black-Scholes model that allows including the smile. The technique presented is a fast analytic approximation to an accurate solution of the valuation problem.

In contrast to previous researches on credit derivatives starting from credit risks, this paper examines default risks affected by the credit derivatives. The linkage of default risks and credit derivatives lies in the implicit options existing in the debt relationships. These options can also...

The importance of collateralization through the change of funding cost is now well recognized among practitioners. In this article, we have extended the previous studies of collateralized derivative pricing to more generic situation, that is asymmetric and imperfect collateralization with the...

If a probability distribution is sufficiently close to a normal distribution, its density can be approximated by a Gram/Charlier Series A expansion. In option pricing, this has been used fit risk-neutral asset price distributions to the implied volatility smile, ensuring an arbitrage-free...
