We provide evidence consistent with a “credit-line drawdown channel” to explain the large and persistent crash of bank stock prices during the COVID-19 pandemic. Stock prices of banks with large ex-ante exposures to undrawn credit lines and large ex-post gross drawdowns declined more,...

We propose a multiplicative factor multi frequency component GARCH model which exploits the empirical fact that the daily standardized forecast errors of one-component GARCH models behave counter-cyclical when averaged at a lower frequency. For the new model, we derive the unconditional variance...

Using a multi-regime forecasting model, we investigate the impact of COVID-19 pandemic on market volatility. We show that daily number of active cases and the Curvature are significant predictors of daily cross-section of both realized volatility and the GJR-GARCH volatility in global equity...
