Ever since the Great Recession, central banks have supplemented their traditional policy tool of setting the short-term interest rate with massive buyouts of assets to extend lines of credit and jolt flagging demand. As with many new policies, there have been a range of reactions from...

We use a series of different approaches to extract information about crash risk from option prices for the Euro-Dollar exchange rate, with each step sharpening the focus on extracting more specific measures of crash risk around dates of ECB measures of Unconventional Monetary Policy. Several...

We extend the work of Bernanke and Kuttner (2005) by examining the impact of monetary shocks and policy tools on aggregate stock and bond returns as well as the stock returns of financial institutions during the recent period of Quantitative Easing (QE) in the U.S. Specially, we test for the...

In response to the COVID-19 pandemic, the US Federal Reserve almost doubled its balance sheet by adding $3 trillion of assets (13% of GDP) in the space of three months, constituting the most aggressive unconventional monetary policy on record. We show that these actions had a substantial effect...

The increasing crypto-stock comovement has spurred concerns over digital assets’ ripple effects and systemic risks. We closely examine this comovement and report two findings. First, the crypto-stock correlation hovered around zero before March 2020 but increased strikingly after. This shift...

We examine the effects of the Asset Purchase Programme (APP) gradually introduced by the European Central Bank from September 2014 onwards. Studying the short-term reaction of financial markets after APP press releases, we analyse the development of bond yields and spreads around these releases....

This paper proposes Spillover Persistence as a measure for financial fragility. The volatility paradox predicts that fragility builds up when volatility is low, which challenges existing measures. Spillover Persistence tackles this challenge by exploring a novel dimension of systemic risk: loss...

This paper studies whether and how the central bank should prick asset price bubbles, if the effect of interest rate policy on bubbles can significantly vary across periods. For this purpose, I first construct a financial accelerator model with an agent-based financial market that can...

Studies of how quantitative easing (QE) impacts asset prices typically look for effects in one- or two-day windows around QE announcements. This methodology underestimates the impact of QE on asset classes whose responses happen outside of this short time frame. We document that QE announcements...
