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...

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...

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 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...

Money markets play a central role in monetary policy implementation. Money market functioning has changed since the financial crisis. This arguably reflects the interaction of two forces: Changes in monetary policy, and changes in regulation. This interaction is not yet well understood. We focus...

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...

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 investigates how changes in the monetary policy framework have affected the overnight money market lending rate for the Dutch segment of the euro area during tranquil and crisis times. We present an EGARCH model on the volatility of the overnight lending rate. The results show that...

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...

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...
