Higher-order Moment Inequality Restrictions for SVARs
We introduce a method that exploits some non-Gaussian features of structural shocks to identify structural vector autoregression (SVAR) models. More specifically, we propose combining inequality restrictions on the higher-order moments of the structural shocks of interest with other set-identifying constraints, typically sign restrictions. We illustrate how, in both large and small sample settings, higher-order moment restrictions considerably narrow the identification of monetary policy shocks compared with what is obtained with minimal sign restrictions typically used in the SVAR ...

Bad Sovereign or Bad Balance Sheets? Euro Interbank Market Fragmentation and Monetary Policy, 2011-2015
We measure the relative role of sovereign-dependence risk and balance sheet (credit) risk in euro area interbank market fragmentation from 2011 to 2015. We combine bank-to-bank loan data with detailed supervisory information on banks? cross-border and cross-sector exposures. We study the impact of the credit risk on banks? balance sheets on their access to, and the price paid for, interbank liquidity, controlling for sovereign-dependence risk and lenders? liquidity shocks. We find that (i) high non-performing loan ratios on the GIIPS portfolio hinder banks? access to the interbank market ...
Why Financial Sanctions Might Not End Russia’s War on Ukraine
A study that examined sovereign risk among oil-exporting countries provides insights into why sanctions may not deter Russia, a major oil-exporter.

The Effect of Possible EU Diversification Requirements on the Risk of Banks’ Sovereign Bond Portfolios
Recent policy discussion includes the introduction of diversification requirements for sovereign bond portfolios of European banks. In this paper, we evaluate the possible effects of these constraints on risk and diversification in the sovereign bond portfolios of the major European banks. First, we capture the dependence structure of European countries? sovereign risks and identify the common factors driving European sovereign CDS spreads by means of an independent component analysis. We then analyze the risk and diversification in the sovereign bond portfolios of the largest European banks ...
