“…This is because such measures provide abundant access to central bank liquidity and lower the cost of debt with positive consequences for bank funding and borrower creditworthiness respectively, thereby supporting bank capital and reducing non-performing loans and loan loss provisioning (Bernanke and Gertler, 1995;Praet, 2016;Bernanke, 2007;Diamond and Rajan, 2006;Freixas and Jorge, 2008;Karadi, 2011, 2013;Kiyotaki and Moore, 2012;Freixas, Martin and Skeie, 2011;Gale, 2009 and2014). At the same time, there may also be some downsides associated with conventional and unconventional monetary policy easing (Rajan, 2005;Taylor, 2008;Allen and Rogoff, 2011;Stein, 2012 and2014;Stiglitz, 2016), including a potential reduction in net interest income (Borio et al, 2017;Alessandri and Nelson, 2015) which could ultimately hamper the transmission of monetary policy (Brunnermeier and Koby, 2017). The net effect of monetary policy on bank profitability therefore remains an empirical question.…”
