Equity basket correlation is an important risk factor. It characterizes the strength of linear dependence between assets and thus measures the degree of portfolio diversification. It can be estimated both under the physical measure from return series, and under the risk neutral measure from...

Using a novel data set and new proxies for rollover losses and market illiquidity, this paper finds that market illiquidity affects corporate bond spreads beyond a liquidity premium through a “rollover risk channel”. This effect is economically significant during episodes of market...

This paper examines whether rollover risk is priced on corporate bond spreads. Using a novel data set and new proxies for rollover risk and market illiquidity, the empirical analysis developed reveals that market illiquidity affects corporate bond spreads beyond a liquidity premium through a...

The calculation of the capital charge for CVA risk, as required by the Basel Committee on Banking Supervision, is usually rather unstable due to the volatility of CDS spreads. Since credit derivatives on single names are not very liquid, the implied adjustments in capital charges could be...

Geopolitical events are widely reported in the press and may influence the risk premium demanded by investors in addition to demand and supply of energy resources. Using the daily geopolitical risk index of Caldara and Iacoviello (2018), we demonstrate that geopolitical risk plays an important...

This paper documents the fact that in options markets, the (percentage) implied volatility bid-ask spread increases at an increasing rate as the option's maturity date approaches. To explain this stylized fact, this paper provides a market microstructure model for the bid-ask spread in options...

This paper discusses a class of methodological issues that frequently arise in the risk management systems such as PFE and CVA engines. Simplified methodology and shortcuts come at a price, sometimes a steep one. To account for model deficiencies and disconnect between the calibration and the...

For most events, risk-neutral outcome probabilities are identical across numeraire currencies. Some events, however, such as elections or referendums, may have an impact on exchange rates. This implies numeraire dependence in risk-neutral outcome probabilities, which leads to different state...

We review the nature of some well-known phenomena such as volatility smiles, convexity adjustments and parallel derivative markets. We propose that the market is incomplete and postulate the existence of intrinsic risks in every contingent claim as a basis for understanding these phenomena. In a...

The carry trade is a zero net investment strategy that borrows in low yielding currencies and subsequently invests in high yielding currencies. It has been identified as highly profitable FX strategy delivering significantly excess returns with high Sharpe ratios. This paper shows that these...
