As the euro area has a predominantly bank-based financial system, changes in the composition and strength of banks’ balance sheets can have very sizeable implications for the transmission of monetary policy. This paper provides an overview of developments in banks’ balance sheets,...

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...

In March 2015, the Eurosystem launched its QE-programme. The asset purchases induced a rapid and strong increase in excess reserves, implying a structural liquidity surplus in the euro area banking sector. Against this background, the first part of this paper analyses the Eurosystem's liquidity...

This paper explores the impact of low (but) positive and negative market interest rates on euro area banks' net interest margin (NIM) and its components, retail lending and retail deposit rates. Using two proprietary bank-level data sets, I find a positive impact of the level of the short-term...

This paper studies the effects of harmonizing collateral policy in a monetary union. In 2007, the European Central Bank replaced national collateral lists with a single list specifying which assets euro area banks can pledge as collateral. Banks holding newly eligible assets experience a...

We study the interaction of expansionary rate-based monetary policy and quantitative easing, despite their concurrent implementation, by exploiting heterogeneous banks and the introduction of negative monetary-policy rates in a fragmented euro area. Quantitative easing increases credit supply...

Negative interest rate policy (NIRP) is associated with a particular friction. The remuneration of banks' retail deposits tends to be floored at zero, which limits the typical transmission of policy rate cuts to bank funding costs. We investigate whether this friction affects banks' reactions...

In June 2014 the ECB became the first major central bank to lower one of its key policy rates to negative territory. The theoretical and empirical literature is silent on whether banks’ reaction would be different when the policy rate is lowered to negative levels compared to a standard...

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...
