We apply sentiment analysis to Twitter messages in Spanish to build a sentiment risk index for the financial sector in Mexico. We classify a sample of tweets from 2006-2019 to identify messages in response to a positive or negative shock to the Mexican financial sector, relative to merely...

We apply text analysis to Twitter messages in Spanish to build a sentiment- based risk index for the financial sector in Mexico. We classify a sample of tweets for the period 2006-2019 to identify messages in response to positive or negative shocks to the Mexican financial sector. We use a...

The value of assets in the digital ecosystem has grown rapidly amid periods of high volatility. Does the digital financial system create new potential challenges to financial stability? This paper explores this question using the Federal Reserve's framework for analyzing vulnerabilities in the...

In this study we disentangle two dimensions of banks' systemic risk: the level of bank tail risk and the linkage between a bank's tail risk and severe shocks in the financial system. We employ a measure of the systemic risk of financial institutions that can be decomposed into two subcomponents...

In this paper we study systemic risks in the Korean banking sector by using two famous systemic risk measures – the MES (marginal expected shortfall) and CoVaR. To compute both measures we employ Engle's dynamic conditional correlation model. Our empirical analysis shows, first, that although...

Consolidation has been a fact of life in the wholesale financial services sector, resulting in fundamental change in the financial architecture and public exposure to systemic risk. The underlying drivers include advances in transactions and information technologies, regulatory changes,...

In this paper we propose a measure of systemic risk in the financial sector, the Expected Systemic Shortfall (ESS) indicator. The ESS-indicator is the product of the probability of a systemic default event and the expected tail loss in case this systemic event occurs. We compute the...

This paper presents a methodology to examine the multivariate tail dependence of the implied volatility of equity options as an early warning indicator of systemic risk within the financial sector. Using non-parametric methods of estimating changes in the dependence structure in response to...
