How do banks operate in a negative policy rate environment? Bank profitability is threatened by policy rate cuts in negative territory because the zero lower bound on retail deposit rates prevents banks from benefiting from cheaper deposit funding costs. Contrary to some earlier research, this...

This paper shows that a rate hike has countervailing effects on banks' risk appetite. It reduces risk when the debt burden of the banking sector is modest. We model a regulator whose trade-off between bank risk and credit supply is derived from a welfare function. We show that the regulator...

This paper studies the impact of the negative interest rate policy (NIRP) on euro area banks’ interest rate margins, using bank-individual data for the 2007-2019 period. An important extension to other studies is our breakdown of banks’ interest rate margin into a funding and lending...

We show that through the safe asset channel the excess liquidity created by QE can lead to higher sovereign bond spreads in the euro area. This unintended effect is most likely in stressed markets when excess liquidity spurs demand for tradeable safe assets, pushing down the interest rate of...

This paper examines the link between interest rates and expenditures, known as the IS-curve. Specifically, we analyse whether the reaction of spending behaviour to monetary policy changes is different in a low compared to a normal interest rate environment. We estimate the nonlinear IS-curve for...

We empirically test whether there is a causal link between the real interest rate and the natural rate of interest, which could be a harbinger of secular stagnation if the real rate declines. Outcomes of VAR models for Japan, Germany and the US show that a fall in the real rate indeed affects...

We present an empirical approach to derive the implicit stance of monetary policy. The indicator can be interpreted as an implied short-term interest rate that is not restricted by the effective lower bound. Factor analysis is used to extract an expectations and term premium component from...

We apply complexity theory to financial markets to show that excess liquidity created by the Eurosystem has led to critical transitions in the configuration of interest rates. Complexity indicators turn out to be useful signals of tipping points and subsequent regime shifts in interest rates. We...

This paper explores the optimal allocation of government bond purchases within a monetary union, using a two-region DSGE model, where regions are asymmetric with respect to economic size and portfolio characteristics: the extent of substitutability between assets of different maturity and...

Using an event study method, we examine how stock markets respond to the policies of the European Central Bank during 1999-2015. We use market prices of futures (government bonds) to identify surprises in (un)conventional monetary policy. Our results suggest that especially unconventional...
