Abstract: Is the transmission of monetary policy to bank lending heterogeneous across euro area countries? This paper employs annual bank level data to test whether the bank lending channel of monetary policy was heterogeneous in the euro area over the period 2007-2016. To do so it follows a simple procedure that allows direct testing of how monetary policy affected similar banks located in different countries. Results indicate that the transmission of monetary policy to bank lending was heterogeneous across countries that were differently exposed to the sovereign debt crisis. On average, the same 1% cut in the policy rate led to a 1.6% increase in lending by banks located in non-stressed countries as opposed to a 0.4% increase for banks located in countries under severe sovereign stress. Unconventional monetary policy – as captured by the ECB shadow rate – was also unevenly transmitted to bank lending. Exposure to sovereign risk is identified as a key source of heterogeneity. Within stressed countries, banks with larger sovereign exposures reacted to monetary easing by expanding lending by less than banks with smaller exposures. As a result, monetary accommodation was smoothly transmitted to lending only by banks with limited exposure to sovereign risk. In response to the same 1% policy rate cut, the credit expansion of highly exposed stressed countries banks was instead 2.75% weaker than that of banks in non-stressed countries. These findings support existing evidence on sovereign risk having direct adverse consequences for bank lending and highlight the extent to which sovereign risk aggravated heterogeneities in the transmission on monetary policy to the real economy via the banking system during the euro area debt crisis.
