This paper provides new empirical evidence that bears on the efficacy of unconventional monetary policies when the main policy rate is negative. When a negative interest rate policy (NIRP) is deployed in concert with rate forward guidance (FG) and quantitative easing (QE), the identification of...

Negative monetary policy rates are associated with a particular friction because the remuneration of retail deposits tends to be floored at zero. We investigate whether this friction affects banks’ reactions when the policy rate is lowered to negative levels, compared to a standard rate cut in...

Monetary policy communication is particularly important during unconventional times, because high uncertainty about the economy, the introduction of new policy tools and possible limits to the central bank 's toolkit could hamper the predictability of policy actions. We study how monetary policy...

We study the effects of a temporary Green QE, defined as a policy that temporarily tilts the central bank's balance sheet toward green bonds, i.e. bonds issued by firms in non-polluting sectors. To this purpose, we merge a standard DSGE framework with an environmental model. In our model,...

We estimate the response of euro area sovereign bond yields to purchase operations under the ECB's Public Sector Purchase Programme (PSPP), using granular data on all PSPP-eligible securities at daily frequency. To avoid simultaneity bias in the estimated relationship between yields and purchase...

Do negative policy rates hinder banks' transmission of monetary policy? To answer this question, we examine the behaviour of Italian mortgage lenders using a novel loan-level dataset. When policy rates turn negative, banks with higher ratios of retail overnight deposits to total assets charge...

In this paper, we survey the nascent literature on the transmission of negative policy rates. We discuss the theory of how the transmission depends on bank balance sheets, and how this changes once policy rates become negative. We review the growing evidence that negative policy rates are...

We study the impact of increasingly negative central bank policy rates on banks' propensity to become undercapitalized in a financial crisis ('SRisk'). We find that the risk impact of negative rates is moderate, and depends on banks' business models: Banks with diversified income streams are...

We use a DSGE model to study the effectiveness of green-asset purchases by the central bank (Green QE), along the transition to a carbon-free economy driven by an emission tax, abstracting from price stability considerations. We find that Green QE helps to further reduce emissions, especially in...
