This Live Wire focuses on safety concerns associated with hydrogen and its main derivatives: ammonia and methanol. After an exhaustive review of the literature and measures on hydrogen safety, the study summarized here found robust, well-established standards developed by reputable institutions....

We demonstrate the asset pricing implications of investors' belief heterogeneity in the frequency of news arrival and its joint impact with heterogeneous beliefs about news content. Investors trade volatility derivatives against each other to speculate on the rate of news arrival: greater...

This report overviews the IMF technical assistance mission to enhance Ukraine's FX derivatives market amidst ongoing economic challenges. In navigating the complex environment, the National Bank of Ukraine (NBU) imposed FX restrictions to manage flows, complicating normalization of financial...

We study the shape of the Bachelier-implied volatility of a spread option on two assets following correlated local volatility models. This includes the limiting case of spread options on two correlated Black-Scholes (BS) assets. We give an analytical result for the at-the-money (ATM) skew of the...

Croatia faces two key labor market challenges: a shortage of labor and the inadequate skills of its existing workforce. These challenges are being shaped by global megatrends, namely, demographic, green, and digital transitions. To address these key challenges, actions are needed on several...

The combination of stochastic derivative pricing models and downside risk measures often leads to the paradox (risk, return) = (−infinity, +infinity) in a portfolio choice problem. The construction of a portfolio of derivatives with high expected returns and very negative downside risk...

We propose a novel framework to assess systemic risk stemming from the inadequate liquidity preparedness of non-bank financial institutions (NBFIs) to derivative margin calls. Unlike banks, NBFIs may struggle to source liquidity and meet margin calls during periods of significant asset price...

This study examines whether changes in the implied volatility of stock options have cross-sectional predictability for future changes in credit default swap (CDS) spreads in the Korean market. The major findings are as follows. First, in the CDS portfolio analysis, when buying a portfolio with...

This study explores an innovative approach to incorporating option strategies into equity portfolios. It presents an alternative direction that institutional investors could take to overcome their current challenges, in a context where traditionally diversified portfolios of only equity and...

We study the implications of deviations from covered interest rate parity for international capital flows using novel data covering euro-area derivatives and securities holdings. Consistent with a dynamic model of currency risk hedging, we document that investors' holdings of USD bonds decrease...

Shocks to a bank's ability to raise liquidity at short notice can trigger depositor panics. Why don't banks take a more active role in managing these risks? We study contingent risk management (hedging) in a standard global-games model of a bank run. Banks fail to hedge precisely when the...

This study investigates whether and how the complexity of derivative use influences the stock price crash risk in China's capital market, a critical question given the growing use of derivatives in emerging economies where governance structures and disclosure standards vary widely. While prior...

The popular Wishart (WI) processes, first introduced by Bru in 1991, exhibit convenient analytical properties for modeling asset prices, particularly a closed-form characteristic function, and the ability to jointly model stochastic volatility and correlation. These features tend to increase...

This paper demonstrates that perfectly calibrating a multi-asset model to observed market prices of all basket call options is insufficient to uniquely determine the price of a best-of call option. Previous research on multi-asset option pricing has primarily focused on complete market settings...

In this paper, we study perpetual American put options with a generalized standard put payoff and establish sufficient conditions for the existence and uniqueness of the solution to the associated pricing problem. As a key tool, we express the Black-Scholes operator in terms of elasticity. This...

A robust model for natural gas prices should simultaneously capture the observed prices of both futures and options. While incorporating a seasonal factor in the convenience yield of the spot price effectively replicates forward curves, it proves insufficient for accurately modelling the options...

This paper enhances the calibration procedure for pricing spread options with liquidity risk. The novelty is the use of Chebyshev interpolation to fit the prices.Numerical experiments reveal that the calibrated parameters are close to the ones obtained by a previous work. However, the fit...

Purpose - In futures markets, margin trading not only relaxes leverage constraints but also entails the risk of margin calls. Therefore, existing studies provide inconsistent evidence on low-risk anomalies, raising challenges in understanding leverage constraints in futures markets. This study...

In this paper, we analyse data from 493 listed banks across 28 countries to investigate the impact and mechanisms through which banks' derivatives holdings influence systemic risk. Our empirical results indicate that banks' derivatives holdings significantly increase systemic risk. Regarding the...

This study unravels the transmission of volatility spillovers between NIFTY 50 spot prices and the options market, addressing a significant gap in existing studies. It captures how market connectedness evolved during the pre-COVID, COVID and post-COVID periods, offering fresh insights into price...
