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 develop a theory of bank liquidity (cash reserve) requirements. Because cash is both observable and riskless, greater cash holdings improve bank incentives to manage risk in the remaining, non-cash portfolio of risky assets. In a model with a single bank, cash is held voluntarily to stem...

We show that negative policy rates affect the supply of bank credit in a novel way. Banks are reluctant to pass on negative rates to depositors, which increases the funding cost of high-deposit banks, and reduces their net worth, relative to low-deposit banks. As a consequence, the introduction...

This paper studies how banks' balance sheets and funding costs interact in the transmission of monetary-policy rates to banks' credit supply to firms. To do so, we use credit-registry data from Germany and Portugal together with the European Central Bank's policy-rate cuts in mid-2014. The...

The paper shows that mispriced deposit insurance and capital regulation were of second order importance in determining the capital structure of large U.S. and European banks during 1991 to 2004. Instead, standard cross-sectional determinants of non-financial firms' leverage carry over to banks,...
